[0037] Working principle: Connect the hydraulic oil circuit with the brake pressure oil port, pass the rated oil pressure, push the movement in the hydraulic cylinder assembly 7, the piston 17 and the lever 5 are locked with the joint, nut and lever 5, thereby driving the lever 5 to put the brake in the open state, and at the same time the piston 17 will compress the disc spring assembly 16 in the hydraulic cylinder assembly 7. When the hydraulic oil is released, the disc spring will push the piston 17 and drive the lever 5 and the brake shoe assembly at the same time, so that it is in the braking state. Before the normal operation of the brake, connect the gate opening alarm device to the corresponding power supply. When the brake is in the open state, rotate the open alarm. The switch on the gate alarm device, adjust the switch position until the indicator light comes on, and then lock the switch. After the first adjustment, the brake will have an alarm state every time the gate is opened, so as to achieve the effect of prompting the brake state. The analog switch 11 of the simulation block is connected to the corresponding displacement display through the power cord, and the rated hydraulic oil is introduced to put the brake in the open state. Adjust the position of the analog switch 11 of the rotating belt simulation block, and the distance between the striker and the switch sensing surface is greater than or equal to three millimeters. Lock the switch. Whenever the friction material is worn, the corresponding value will be displayed on the displacement display.
[0038] We press the button 22 to slide on the inner wall of the lever 5, thereby driving the fixing column 23 to slide on the inner wall of the trapezoidal plate 25. The shape formed by the strip opening 26 opened inside the trapezoidal plate 25 enables the fixing column 23 to push the trapezoidal plate 25 to slide. At the same time, the trapezoidal plate 25 will also squeeze the spring 24, so that the spring 24 can store elastic potential energy, and then give the trapezoidal plate 25 a force in the opposite direction to reset it, so that the column 20 and the entire structure on the top side can be taken out.
