Jiaozuo brake

The electric hydraulic thruster consists of two main parts. When the thruster is powered on, its push rod quickly rises and the iron wedge is lifted by a lever and transmission mechanism to ensure normal operation of the crane; When the thruster is powered off, the push rod of the thruster is subjected to spring force and the iron wedge is placed on the steel rail through a lever. Wedging the wheels during a sudden storm provides safety protection.

As shown in Figure 2, the piston cylinder body (4) is equipped with a one-way valve (8) and a reset hole (10) at the top, a large circular hole (11) in the center that can be matched with the one-way piston (5), and a sealing ring (9) inside the hole wall. The support component (1) is located at the bottom of the piston cylinder body (4), with an oil passage (13) in the center and a sealing ring (12) on the side of the outer circle. As shown in Figure 3, the unidirectional piston (5) is located in the upper part of the piston cylinder (4), which is cylindrical in shape and is installed in the large circular hole (11) of the piston cylinder (4). There are four cantilever beams (15) in the center of its lower bottom, and a sealing ring (14) on the outer side of the lower bottom. The piston (3) is located in the lower part of the piston cylinder (4), and its upper end is placed in the one-way piston cantilever beam (15), connected to the push rod (7), with a pressure plate (6) installed at the top. 45 push without signs_ copy

Its overall structure consists of a fixed component (18) placed inside the upper shell (19) of the thruster, an upper end connected to a brake lever (21), and a lower end placed above the lower shell (17) by a support component (1). The impeller (2) is installed on the motor (16) shaft through the oil passage (13), located in the gap between the piston (3) and the support member (1). Brake operating conditions

Instructions for use:

1. Installation test: First, check whether the thrust on the nameplate of the electric hydraulic thruster product matches the required force: remove oil stains on the motor and body surface, and check whether the push rod lifting is smooth. Unscrew the oil filling plug 5 (Figure 3) and oil level plug 3, and inject suitable and pure hydraulic oil until the screw hole 3 is reached. Then tighten plug 3 and plug 5. According to different ambient medium temperatures, it is recommended to follow Table 6 for hydraulic oil. The temperature of the surrounding medium is+45 ℃~+21 ℃+20 ℃~+0 ℃+0 ℃~-15 ℃~-15 ℃~-30 ℃ - below 30 ℃. 20 # mechanical oil GB443-64, 10 # transformer oil (freezing point -10 ℃) SYB1351-62, 25 # transformer oil (freezing point -25 ℃) SYB1351-62, instrument oil (freezing point -60 ℃), GB487-65, a mixture of alcohol and glycerol. It is recommended to use oil to connect the lower part of the hydraulic thruster with a pin, and connect the connecting rod of the crossbeam with a lever device with a pin.

There is no gas or dust in the surrounding medium that is sufficient to corrode metals and damage insulation.

The brake is surrounded by Class B insulation, with voltage fluctuations not exceeding+5% and -15% of the rated voltage, and its working mode is continuous working

During installation, ensure the accuracy of the fit between the transmission shaft and the brake.

Before installation, the brake must be cleaned thoroughly, and there must be no oil or dust on the friction surface and inside the brake. A series of specialized devices that can forcibly reduce the driving speed of a car. The braking system mainly consists of four parts: energy supply device, control device, transmission device, and brake. The main function of the braking system is to slow down or even stop a moving car, maintain a stable speed when driving downhill, and keep a stopped car stationary. The braking system is essential for every type of vehicle, and without it, the scene would be unimaginable. In the braking system, brakes are also very important. Generally speaking, the role of front wheel braking is greater, surpassing the contribution of rear wheel braking. The front brakes are generally divided into two types: drum and disc.

In general passenger cars, the braking devices of the front and rear wheels are often different. If all four wheels are disc brakes, the front wheels are mostly ventilated disc brakes, and the rear wheels are mostly ordinary disc brakes. If the disc brake is mixed with the drum brake, the front wheel adopts Disc brake, and the rear wheel adopts drum brake. Multiple thrusters

Use and Maintenance

The working condition of the brake shall be checked regularly, and the following items shall be emphasized during the inspection: 1. Whether the brake components can move normally and whether the adjusting nuts are fastened. 2. Whether the components of the thruster are normal and whether the hydraulic oil is sufficient. Is there any oil leakage or seepage. Check if the insulation of the incoming wires is good. 3. The size H1 should not be less than the small dimensions listed in Table 1. If it exceeds the requirements, it must be adjusted immediately, otherwise the braking effect will be lost. 4. Check whether the brake shoe rests on the brake wheel normally, whether the friction surface is in good condition, and whether there is greasy dirt. When the thickness of the brake pad reaches the values in Table 2, the brake pad should be replaced. 5. The temperature of the brake wheel should not exceed 200 ℃. 6. If cracks are found on the lever and spring, they should be replaced.
