Jiaozuo brake

Electric hydraulic tile brake, abbreviated as tile brake, has a simple structure, convenient manufacturing and installation, dual tile without axial force, convenient maintenance, and low price. There is a certain amount of impact and vibration. Widely used in various lifting and transportation machinery, petroleum machinery, mining machinery, excavation machinery, metallurgical machinery and equipment, construction machinery, ship machinery, etc. Brakes can be divided into two types according to their purpose: stop type and speed control type. The former only has the function of braking and supporting moving objects; the latter can also adjust the speed of object movement in addition to the above functions.

According to the control method, it can be divided into manual, automatic, and hybrid.

It can be divided into normally open and normally closed according to its working state. The normally open type is often in a released state and requires external force to achieve braking. The normally closed type is often in a closed or braking state, and only by applying external force can the braking state be released. The lifting mechanism in lifting machinery often uses a normally closed brake system, while the main brakes of various vehicles use a normally open brake system.

Common brakes often use friction brakes, which can be divided into block type, belt type, and disc type according to their structural characteristics. They all utilize the frictional resistance moment generated between friction components to consume the kinetic energy of mechanical moving parts, in order to achieve the purpose of braking. It mainly consists of three parts: brake frame, friction components, and driving device. The brake frame is the foundation for the installation and support of other parts of the brake. The friction elements are in contact with the brake wheel to generate the brake Friction torque. The driving device amplifies and transmits the driving force acting on the brake to the friction element to achieve braking (tight braking) or to release the friction element from contact with the brake wheel.

The working conditions of using electrically powered hydraulic brakes are as follows:

1. The common electric hydraulic brake mainly operates by pushing the actuator to open when the point is reached;

2. The braking force during braking is provided by the spring, and the electric hydraulic brake does not work at this time;

3. If you want to power on for a long time, even if the brake is in an open state for a long time, theoretically there is no problem. However, in actual use in the factory, the motor of the thruster is prone to malfunction. Generally, electric hydraulic thrusters have a wrench for manual position maintenance, which means that after opening, the claw can be manually clamped onto the support rod, and after power outage, it is still in the open state;

4. For electric hydraulic brakes in the normally open state, the normally open state can be used, which relies on hydraulic braking and spring opening.

When the excitation coil of the block brake is energized, it will attract the armature. Through the action of the push rod, the two brake arms overcome the pulling force of the spring and rotate outward. This way, the pads connected to the two brakes release the brake wheels, allowing the machinery to operate freely. To brake, simply cut off the electric probe, release the armature from the excitation coil, and clamp the two brake arms inward under the tension of the spring. At this point, the tile will hold the brake wheel tightly. For safety reasons, this type of brake adopts a normally closed structure with power off braking.

What is the adjustment method for electric hydraulic brakes?

1. Loosen the spring of the braking torque.

2. Manually lift the thruster triangle and adjust the upper adjustment screw to make the opening gap of the brake shoe 1.5mm (brake shoe and brake wheel). Adjust the lower limit screw of the brake bracket to evenly distribute the opening gap on both sides of the brake shoe.

3. Adjust the torque spring to meet the required scale.

4. Tighten all locking nuts. (After the gate adjustment is completed)

5. When the brake shoe is worn to the required level, replace it and adjust it according to the above steps. During the wear process of the brake shoe, due to the wear of the brake shoe, the triangle plate of the thruster is lowered. When the smooth rod of the thruster drops close to the compensation limit mark, the brake gap should be adjusted in a timely manner.
