[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1-5 This embodiment provides the following technical solution: an electro-hydraulic horizontal disc brake, including a base 1, a frame 2 fixedly connected above the base 1, an upper brake plate 3 and a lower brake plate 4 hinged to the upper part of the frame 2, an upper brake arm 9 and a lower brake arm 10 hinged to the frame 2, one end of the upper brake arm 9 is hinged to the upper brake plate 3, one end of the lower brake arm 10 is hinged to the lower brake plate 4, and the other ends of the upper brake arm 9 and the lower brake arm 10 are hinged together by an adjusting rod 11, which is used to change the linkage distance between the upper brake arm 9 and the lower brake arm 10. In some embodiments, the adjusting rod 11 includes an adjusting screw and adjusting nuts respectively disposed at both ends of the adjusting screw. The adjusting nuts are correspondingly hinged to the upper brake arm 9 and the lower brake arm 10. By rotating the adjusting screw, the adjusting nuts can be moved along the axis of the adjusting screw, thereby changing the distance between the upper brake arm 9 and the lower brake arm 10, achieving the purpose of adjusting the braking gap. The operation is simple and convenient, ensuring stable braking performance.

[0018] A brake spring assembly 12 is fixedly connected to the base 1. A lever 13 is hinged to the top of the spring rod on the brake spring assembly 12. One end of the lever 13 is hinged to the upper brake arm 9. When the brake is in the braking state, the spring of the brake spring assembly 12 is in the compressed state. The spring rod applies a pulling force to the lever 13, and the lever 13 rotates around the fulcrum, causing the upper brake arm 9 to swing. The upper brake arm 9 drives the lower brake arm 10 to swing synchronously through the adjusting rod 11, so that the friction plates 7 on the upper brake plate 3 and the lower brake plate 4 are in close contact with the brake disc, thereby achieving braking.

[0019] A pusher 14 is fixedly connected to the base 1. A drive rod 15 is hinged to the piston end of the pusher 14. The other end of the drive rod 15 is hinged to the other end of the lever 13. When the pusher 14 is working, its piston end extends and pushes the drive rod 15. The drive rod 15 applies a thrust to the lever 13, overcoming the spring force of the brake spring assembly 12, causing the lever 13 to rotate in the opposite direction around the fulcrum, which drives the upper brake arm 9 and the lower brake arm 10 to swing. The friction plates 7 on the upper brake plate 3 and the lower brake plate 4 separate from the brake disc, thus releasing the brake.

[0020] Both the upper gate plate 3 and the lower gate plate 4 are connected to friction plates 7 via quick-release mechanisms. The quick-release mechanisms on the upper gate plate 3 and the lower gate plate 4 are the same. The quick-release mechanism on the upper gate plate 3 includes locking bolts 5, and there are at least two locking bolts 5. One end of the locking bolt 5 passes through the upper gate plate 3 and is threaded to the bolt hole 6 on the friction plate 7. With the quick-release mechanism, the operator only needs to unscrew the locking bolts 5 to remove the worn friction plate 7, replace it with a new friction plate 7, and then tighten the locking bolts 5. The entire replacement process does not require disassembling other complex parts, which greatly shortens the replacement time and improves the operating efficiency of the equipment.

[0021] Example 2 like Figure 3-5 As shown, the friction plate 7 is also equipped with a wear warning mechanism for real-time monitoring of the wear status of the friction plate 7 and issuing warnings. The wear warning mechanism includes a conductive metal wire 8 and a signal processor. The conductive metal wire 8 is provided in at least two layers and is disposed inside the friction plate 7. The signal processor is fixedly connected to the frame 2. The input end of the signal processor is connected to the output end of the conductive metal wire 8. The output end of the signal processor is connected to a warning light and a buzzer. In some embodiments, the warning light is a three-color warning light. The wear warning mechanism enables graded warning of the wear status of the friction plate 7. Operators can accurately determine the remaining service life of the friction plate 7 based on different warning signals, avoiding safety accidents caused by excessive wear of the friction plate 7. At the same time, it reduces the number of unnecessary shutdowns for inspection and improves equipment operating efficiency.

[0022] In some embodiments, the conductive metal wire 8 is embedded in the friction plate 7 in a "U" shape. This structure can increase the contact area between the conductive metal wire 8 and the friction plate 7, ensuring that the conductive metal wire 8 can accurately reflect the degree of wear during the wear process of the friction plate 7.

[0023] The conductive metal wires 8 are arranged in three layers, with the spacing between each layer of conductive metal wires 8 distributed along the thickness direction of the friction plate 7: the first layer of wires is 1.2-1.8mm away from the working surface of the friction plate 7; the second layer of wires is 0.6-1.0mm away from the working surface of the friction plate 7; and the third layer of wires is 0.2-0.4mm away from the working surface of the friction plate 7. When the friction plate 7 wears down to different layers of conductive metal wires 8, the conductive metal wires 8 will break due to wear. After the signal processor detects the circuit disconnection signal, it will trigger different warning modes so that the operator can accurately judge the remaining service life of the friction plate 7.

[0024] The signal processor also includes a wireless communication module, which is a Bluetooth or LoRa module. It can upload the wear level signal of the friction plate 7 to the equipment management system and also supports receiving remote self-test commands. Staff can view the operating status of the brake in real time through the equipment management system without on-site inspection, which greatly improves management efficiency. The remote self-test function can detect faults in the signal processor and conductive metal wire 8 in a timely manner, ensuring the reliability of the wear warning mechanism.

[0025] The working principle of this utility model is as follows: When the equipment needs to brake, the pusher 14 stops working, and its piston end retracts under the action of the return spring. The spring of the brake spring assembly 12 releases elastic potential energy, and pulls one end of the lever 13 through the spring rod. The lever 13 rotates around the central fulcrum, and its other end pushes the drive to contract. Lever 13 drives the upper brake arm 9 to swing around the hinge point with the frame 2. The upper brake arm 9 drives the lower brake arm 10 to swing synchronously through the adjusting rod 11, so that the friction pads 7 on the upper brake plate 3 and the lower brake plate 4 move towards the brake disc and fit tightly together. Braking is achieved by the friction between the friction pads 7 and the brake disc. During the use of friction plate 7, as the degree of wear increases, the thickness of friction plate 7 gradually decreases; When the friction plate 7 wears down to the position of the first layer of conductive metal wire 8, the first layer of conductive metal wire 8 is broken. The signal processor detects the circuit disconnection signal and controls the warning light to emit a yellow warning light, indicating to the staff that the friction plate 7 has been worn to a certain extent and needs to be replaced. When the friction plate 7 continues to wear down to the position of the second layer of conductive metal wire 8, the second layer of conductive metal wire 8 is broken. The signal processor controls the warning light to emit an orange warning light, and at the same time the buzzer emits an intermittent warning sound to remind the staff that the wear of the friction plate 7 has increased and should be replaced as soon as possible. When the friction plate 7 wears down to the position of the third layer of conductive metal wire 8, the third layer of conductive metal wire 8 is broken. The signal processor controls the warning light to emit a red warning light, the buzzer to emit a continuous alarm sound, and the emergency wear signal is uploaded to the equipment management system through the wireless communication module, prompting the staff that the friction plate 7 is severely worn and must be stopped and replaced immediately to avoid brake failure.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
