The function of brake device in coal mine belt conveyor! Regarding coal mine belt conveyors, first of all, let me raise a few related questions, specifically: What are the specific aspects of different types of coal mine belt conveyors that may differ? Why is there a need for brakes in coal mine belt conveyors? And what is the formula for calculating the motor power of coal mine belt conveyors? Now that we have these questions, there is no time to delay. Let's give them the corresponding answers now, so that we can understand them clearly.1. What are the specific aspects that may vary among different types of coal mine belt conveyors?Coal mine belt conveyors can be said to have a complex variety and are also widely used in applications. However, there are certain differences between different varieties. If summarized, it mainly focuses on four aspects: transportation method, transportation speed, power requirements, and load-bearing method. Moreover, due to the special requirements corresponding to the transportation of objects, different types of coal mine belt conveyors cannot be universally used.Why is there a need for brakes in coal mine belt conveyors?This is because the brake in the coal mine belt conveyor has two functions: to prevent the coal mine belt conveyor from walking and to inspect the parking safety equipment in the machine. Therefore, using the brake can effectively reduce the parking time of the coal mine belt conveyor, which is to achieve emergency braking. Moreover, when encountering an incident, it can also avoid the escalation of the incident and avoid serious consequences.What is the calculation formula for the motor power of a coal mine belt conveyor?The calculation formula for the motor power of a coal mine belt conveyor is as follows: P=F × V ÷ 60 ÷ η Where P is the motor power, F is the traction force, V is the speed, and η, It refers to the transmission Mechanical efficiency, which is generally 0.8.In this formula, F also has a corresponding calculation formula, which is: F= μ G. During this period, μ Is the coefficient of friction, which is related to the state of the wheels and guide rails. And G is generally 40 tons, which is 400KN. Therefore, we need to have a clear understanding of these two formulas and calculate them correctly. YWZ9 Explosion-proof Real ViewThe commonly used liquid is oil, but due to the need to consume all the kinetic energy of the belt conveyor in a short braking time, the oil temperature is bound to rise sharply. Therefore, a circulation system must be used in the oil circuit to facilitate heat dissipation. It has the advantage of large braking torque and adjustable adjustment, but due to the equipment such as a pump station, the equipment has a large volume. Belt conveyors, also known as belt conveyors, are widely used in various industries such as home appliances, electrical appliances, machinery, tobacco, and food, for the assembly, testing, debugging, packaging, and transportation of objects. The conveying line body of the belt conveyor can be selected according to the conveying process requirements of different materials. Perform various control methods such as normal continuous operation, rhythm operation, and variable speed operation. The conveyor line body of the belt conveyor can also be adapted to local conditions by selecting straight lines, curves, and slopes to transport materials. The belt conveyor brake has strong conveying capacity, long conveying distance, simple structure, and easy maintenance, making it very convenient to implement programmed control and automated operation

MoreAdjustment method for service brakesService brake: A device that stops a vehicle from continuing to move or move while it is in motionParking brake: A device used to prevent the wheels from rolling when a vehicle is parked on a surface with a certain slope, in order to prevent the vehicle from moving due to gravity or other reasonsBrake pedal: It belongs to one of the above service brakes and parking brakes, and uses pedal type for service or parking brakes. Press the pedal to stop the wheels from rotatingThe adjustment of the service brake is divided into comprehensive adjustment and local adjustment. Comprehensive adjustment is applicable to situations where the coaxiality between the brake shoe and the working surface of the brake drum is damaged due to the loosening of the shoe shaft after the brake is disassembled and repaired. Local adjustment is made to reduce the gap between the brake shoe and the brake drum after the brake friction plate is worn.The order of comprehensive adjustment is:Loosen the nut that fastens the shoe shaft.Loosen the nuts of the fastening bolts for the cam support seat and bracket.Disconnect the connecting fork on the brake chamber push rod from the brake adjustment arm.Rotate the shoe shaft so that the shaft end markings are located close to each other.Rotate the cam adjusting arm by hand to make the shoe cling to the brake drum. Use a Feeler gauge gauge from the inspection hole of the brake drum to check whether the two ends of each shoe cling to the brake drum. If a gap is found at the end of the shoe shaft, remove it by rotating the shoe shaft. Tighten the nut of the shoe shaft and the nut of the fastening bolt of the cam support seat and bracket at the adjusted position.The brakes of the crane must be well maintained. Now, Xinxiang Zhongrui Lifting Machinery Co., Ltd. will introduce YWZ9 HD brakes to usBefore the operation of the crane, the brake should be checked for the sensitivity of the connecting rods and pins at each movable contact point, whether there is any sign of loosening or falling of the bolts, whether the wear of the brake pads has reached the invalid standard, whether the spacing between the two pads and the outer surface of the brake wheel is equal when the brake pads are open, whether there is any sign of loosening between the brake wheel and the transmission, whether the interference between the shaft and the hole is met, and whether there is any sign of loosening when tightening the bolts, Is there any oil stains on the surface of the brake wheel, and is there any significant scratches or signs of falling on the surface of the brake wheel. Is there any jamming or wear at the hinge, and is the hydraulic system normal.Large cranes are used in the metallurgical industry to transport molten steel for smelting furnaces. There are generally five main mechanisms: main lifting, auxiliary lifting, crane, main trolley, and auxiliary trolley mechanisms. The motor is installed on the high-speed shaft, and the drum is installed on the low-speed shaft. The high-speed shaft and low-speed shaft are connected together through a reducer. The traditional lifting mechanism brake is set on the high-speed shaft brake.

MoreTo what extent is the friction plate of the disc brake wornMany disc brakes are equipped with a wear indicator. When the friction plate is worn to a predetermined thickness, the indicator will contact the brake plate and generate a high-frequency squeal. Therefore, if the above fault is found in the inspection, the friction plate must be replaced in time. (Note: Some countries may have regulations regarding the replacement of friction discs before they reach a small thickness, so the wear indicator should be calibrated according to their own requirements.)If the wear indicator has been deformed, it is easy to replace it because it is difficult to correct its position from behind. If it is found during the inspection that the friction plate has peeled off, separated, cracked or severely damaged, or brake fluid has flowed out, the friction plate should be replacedSBD friction plate imageCompared with the drum brake, the working surface of the disc brake is flat and heat transfer occurs on both sides. When the disc rotates, it is easy to cool down and is not prone to large deformation. The braking efficiency is relatively stable. After a long time of use, the brake disc has enhanced its braking effect due to high temperature expansion; The drum brake has a single side heat transfer and a large temperature difference between the inner and outer sides, which makes the brake drum prone to deformation. At the same time, after prolonged braking, the brake drum expands due to high temperature, and the braking efficiency is weakened. In addition, the disc brake is simple in structure, convenient in maintenance, and easy to realize automatic adjustment of brake clearance.

MoreFault Detection and Solution of Disc BrakeDuring the use of the disc brake, there are problems such as insufficient braking force, noise during braking, etc., which affect the normal use. We need to find the causes of the problems and solutions in a timely manner, and quickly eliminate the impact of the problems on the machine.Reason:(a) Brake oil leakage;(b) There is air in the brake oil circuit;(c) The oil seal of the wheel hub is damaged, and there is oil stains on the clamp plate;(d) Severe brake wear and burning of the friction surface;(e) The air pressure adjustment of the air circuit is too low.Solution:1. By changing the brake pad material, a slightly softer brake pad material can be used to improve the friction coefficient and increase the braking force.2. Remove foreign objects from the debris discharge groove of the brake pad. If the debris discharge groove of the brake pad is covered by foreign objects, it will lose its function of removing dust and moisture during braking, resulting in a decrease in braking force.The disadvantage of the disc brake is that the friction plate acts directly on the disc, without automatic friction amplification, and the braking efficiency is low. Therefore, if the brake actuating pipeline pressure required for the hydraulic braking system is high, additional power auxiliary devices must be installed; When also used for parking brake, the added parking brake transmission device is more complex than the drum brake, so its application on the rear wheels is limited.Friction plate wearMany disc brakes are equipped with a wear indicator. When the friction plate is worn to a predetermined thickness, the indicator will contact the brake plate and generate a high-frequency squeal. Therefore, if the above fault is found in the inspection, the friction plate must be replaced in time. (Note: Some countries may have regulations regarding the replacement of friction discs before they reach a small thickness, so the wear indicator should be calibrated according to their own requirements.)If the wear indicator has been deformed, it is easy to replace it because it is difficult to correct its position from behind. If it is found during the inspection that the friction plate has peeled off, separated, cracked or severely damaged, or brake fluid has flowed out, the friction plate should be replaced.SB brake usage diagramBrake caliper 1 is generally designed to move axially relative to brake disc 4. There is a hydraulic oil cylinder 9 on the inner side of the brake disc, and a fixed brake block 5 on the outer side is attached to the caliper body. When braking, the brake fluid is pressed into the oil cylinder, and under hydraulic pressure, the piston moves to the left, pushing the movable brake pad to move to the left and press against the brake disc. Therefore, the brake disc gives the piston a reaction force to the right, causing the piston and brake caliper body to move to the right along the guide pin 2, until the fixed brake pad 5 on the left side of the brake disc is also pressed onto the brake disc. At this time, the brake pads on both sides are pressed on the brake disc, and the brake pad brake disc generates Friction torque to prevent the wheel from rotating, so as to achieve braking.The brake disc 1 is fixed to the wheel hub, and the brake caliper 5 is fixed to the axle, which cannot rotate or move axially along the brake disc. The brake caliper is equipped with two brake wheel cylinder pistons 2, which press against the brake pads 3 on both sides of the brake disc. When the driver steps down the brake pedal to brake the car, the brake fluid coming from the master cylinder is pressed into the brake wheel cylinder, the hydraulic pressure of the brake wheel cylinder rises, the pistons of the two wheel cylinders move to the brake disc under the hydraulic pressure, press the brake block against the brake disc, and the brake block brake disc generates Friction torque to prevent the wheel from rotating, so as to achieve braking.Damaged brake partsWhen adjusting the brake caliper and friction plate of the disc brake, the installed parts (such as springs, gaskets, keyways, clamps, pins, bushings, etc.) may have been worn, loosened and aged. If they continue to be used, they may produce eccentric noise. In addition, eccentricity can also cause hot spots and glaze quality on the rotor surface, so when repairing the brake, the parts should be inspected and replaced if there are any problems.

MoreElectric hydraulic brake manufacturers introduce the characteristics of six types of brakes: brakes can be divided into mechanical brakes, air brakes, hydraulic brakes, electric brakes, and manual brakes according to the driving components (categories). Common brakes are divided into friction type and non friction type. Friction type brakes are also divided into external block brake, internal expansion shoe brake, belt brake and disc brake, etc. Preventive maintenance of brakes usually includes: quantity inspection, quality inspection and regular replacement of hydraulic oil for hydraulic rod brake release; Regularly inspect and refuel the brake for wear and tear at each point; Timely replacement of brake bands and brake wheels after wear; Check and adjust the working status of the brake (such as the working stroke of the double brake push rod should be consistent, the stroke of the push rod of the two brake release devices should be controlled within lOmm, and the actions of the two brake release devices must be synchronized); Inspection of hydraulic push rod brake release motor and control circuit, etcWith the development of equipment towards large-scale, ultra large-scale, and automation, brakes are rapidly developing towards heavy-duty, multifunctional, intelligent, and maintenance free braking conditions. The overloading of braking conditions is to meet the matching braking requirements of large and ultra large heavy-duty mechanisms; Multi function mainly includes brake release interlocking function, manual release function, liner wear limit limit limit (interlocking) function, wear automatic compensation function, etc; Intelligence refers to the introduction of digital and computer technology into control systems; Maintenance-free refers to turning the manual adjustment function of the brake into an automatic adjustment function, while achieving high reliability of brake action and performance. In addition, achieving real-time maintenance of industrial brakes through remote monitoring is also an important development direction for brakes.The safety brake is a mechanical brake set on the final shaft (drum shaft) of the transmission mechanism, generally only used on important lifting mechanisms (such as crane lifting mechanisms, boom pitch mechanisms, and inclined downward belt conveyors). Since the 1980s, with the rapid development of lifting and loading and unloading machinery towards large-scale and ultra large-scale, specialized and specialized, as well as semi-automatic and automated directions, the application of safety brakes has also rapidly developed. At present, safety brakes have been widely used in large-scale port specialized loading and unloading machinery, and large-scale specialized lifting equipment (such as power station gantry cranes, casting cranes, cable cranes, etc.) and inclined belt conveyors are being promoted and applied.Specific production model:YT1, ED, YTD.BYT1, BED, ED2, MYT1, ZED, DEd series electric hydraulic thrustersJZ, MW, TJ2, ZWZA, ZWZ3 series electromagnetic brakesYWZ, YWZ3, YWZ4, YWZ5, YWZ8, YWZ10, YWZ9, YWZ13, YW, YWL series electric hydraulic brakesBYWZ, BYWZ3, BYWZ4, BYWZ5, BYWZ8, BYWZ10, BYWZ9, BYWZ13, BYW series electric hydraulic brakesQP, CQP, QPC, CQPL, QPL, PDA series pneumatic caliper disc brakeDCPZ250, DCPZ300, DCPZ400 series electromagnetic caliper disc brakeYPZ2, YPZ3, YPZ1, YP series arm disc brakeSPZ symmetrical brake arm disc brakeSBD, SB series safety brakesSH, ST series hydraulic failure protection brakeDADH, ADH, ADP series hydraulic direct acting brakesSE series electromagnetic failure protection brakeSP series pneumatic failure protection brakeYFX, YDGZ, YLBZ, Series Windproof Wedge BrakesYQP hydraulic disc brakeXinhua Wu ED thrusterElectric hydraulic thruster ED-23/5, thrust 220N, stroke 50mmElectric hydraulic thruster ED-30/5, thrust 300N, stroke 50mmElectric hydraulic thruster ED-50/6, thrust 500N, stroke 60mmElectric hydraulic thruster ED-80/6, thrust 800N, stroke 60mmElectric hydraulic thruster ED-121/6, thrust 1250N, stroke 60mmElectric hydraulic thruster ED-201/6, thrust 2000N, stroke 60mmElectric hydraulic thruster ED-301/5, thrust 3000N, stroke 60mmOil for electric hydraulic thrustersThe thruster has been equipped with hydraulic oil according to regulations when leaving the factory. If the thruster has been stored for a long time (more than 6 months), screw out the plug (see Figure 1) before use to check whether the oil level is normal. If the oil level does not reach the specified level, hydraulic oil should be added to the specified level (see Figure 1), otherwise the thruster cannot work properly. The hydraulic oil grade can be found in Table 2 (Mobil, Shell, and other hydraulic oils equivalent to the grade in the table can also be used), and the hydraulic oil filled must not contain impurities or dirt (it should be filtered). When adding hydraulic oil, the push rod should be slowly pulled up and down several times to remove air from the hydraulic cylinder and ensure sufficient oil is added.ambient temperature-25 ℃~+50 ℃ -45 ℃~+50 ℃Hydraulic oil grade DB-25 DTE-21 (Mobil) HL-10 YH-10 DB-45The hydraulic oil used in the hydraulic system is selected based on the working environment when designing the system. The viscosity of the hydraulic oil is an important reference index when selecting it. The weather in your area is relatively cold, which can affect the viscosity of the hydraulic oil. Therefore, a good approach is to ask the design manufacturer. Because the system is designed by them, the designer has the right to speak. I myself also study hydraulic design, But hello, don't use hydraulic oil indiscriminately. Because the hydraulic system is quite particular about using hydraulic oilFault analysis and troubleshooting of the hydraulic push rod brake of the crane crane. It is difficult to lubricate and refuel each movable hinge point of the brake. According to maintenance regulations, the hinge point is lubricated with thin oil, but due to the structure of the brake, it is difficult to inject and store oil at the hinge point. Every time the driver refuels, they slowly inject the oil gun into the gap of the hinge point, and if they are not careful, it will drip onto the brake wheel or brake band. If the on-site maintenance conditions are fully considered in the design, it will bring more convenience to the on-site use.At present, there are many faults in the hydraulic push rod brake used by people, and the main fault phenomena are:(1) The square coupling between the motor shaft and the impeller shaft became loose and fell off, causing the motor shaft to spin while the hydraulic cylinder did not move.(2) The push rod of the hydraulic push rod brake release device is bent and deformed, and the brake release device is not working properly.(3) The hydraulic push rod brake spring is broken and the brake cannot be closed.(4) The movable hinge point of the brake frame is stuck, and the opening and closing actions of the brake are slow or not moving.(5) The movable hinge pin of the brake frame is loose, and the brake does not work properly;(6) Brake bands and wheels are severely worn, resulting in reduced or lost braking torque.(7) The drive motor of the hydraulic push rod brake release device is out of phase, and the motor and brake release device do not operate.
