Abstract
Description
Technical Field
[0001] This utility model relates to the field of gap detection technology for disc brake devices, and in particular to a gap detection device for disc brake devices. Background Technology
[0002] Accurate detection of brake clearance is fundamental to ensuring the normal operation of disc brakes. Precise clearance detection can promptly identify potential problems in the braking system, preventing serious safety accidents such as brake failure caused by improper brake clearance. At the same time, with the continuous expansion of mining scale and the increase in mining depth, the performance requirements for mining machinery are also becoming higher and higher. This necessitates more advanced and reliable clearance detection devices to meet the needs of actual production.
[0003] In existing technologies, gap detection for disc brake devices in mining machinery mainly employs some traditional mechanical structures and technical principles. A common approach is to use simple mechanical measuring tools to manually measure the brake gap periodically. This method relies on the operator's experience and skills, the measurement process is cumbersome, and the measurement accuracy is difficult to guarantee. Some electrical detection methods use simple sensors installed on the brake device to obtain relevant signals, but these sensors are often simple in structure and have limited functions. In terms of mechanical structure, some existing technologies use fixed frame structures to install sensors, which lack flexibility and adjustability.
[0004] However, existing technologies have a prominent problem: due to the harsh mining environment with a large amount of dust and other impurities, the gap detection device is prone to dust accumulation on the sensors during long-term operation. This dust adheres to the sensitive parts of the sensors, affecting the accurate acquisition and transmission of braking gap signals. As the dust accumulates, the sensor's performance gradually deteriorates, leading to problems such as increased measurement errors and signal instability, which can cause sensor failure. Once the sensor fails, it is impossible to accurately detect the braking gap, thus failing to detect potential safety hazards in the braking system in a timely manner, which can lead to accidents such as brake failure, posing safety risks and economic losses to mining production. Therefore, a gap detection device for disc brake systems is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a gap detection device for disc brake devices, aiming to improve the problem of sensor performance degradation or even failure caused by dust accumulation in the prior art.

[0023] This utility model has the following beneficial effects:
[0024] In this invention, pulling the placement block causes the outer shell to move, which in turn causes the spring to rebound, thereby displacing the limiting post and causing the outer wall of the ball to detach from the inside of the shell. This achieves the effect of quick disassembly of the sensor for easy maintenance, solves the problem of sensor performance degradation or even failure caused by dust accumulation, and improves the convenience of disassembly of mining machinery.
[0025] In this invention, the electric push rod is activated, causing the connecting plate to move and the sliding block to slide on the outer wall of the fixed block. At the same time, the rack moves. Since the rack meshes with the gear, the sliding of one side of the rack causes the other side to rotate, thereby causing the two clamps to move synchronously towards the middle, achieving the effect of clamping the brake. This avoids the uncertainty of manual operation, reduces the impact of human factors on the braking system, and improves work efficiency and safety. Attached Figure Description

[0033] 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.
[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a gap detection device for a disc brake device, comprising a detection bracket 1 made of high-strength alloy steel, which has excellent compressive and deformation resistance, and can stably bear the weight of other components and resist various external impacts in the complex and harsh working environment of a mine. A brake 2 is provided on the side wall of the detection bracket 1, which can respond quickly when braking demand occurs and achieve braking function through friction with the brake disc, providing reliable braking guarantee for the safe operation of mining machinery. A housing 3 is provided on the side wall of the detection bracket 1, and a sensor 5 is provided inside the housing 3, which can detect the gap change of the disc brake device in real time and accurately, and convert these data into electrical signal output. A disassembly and assembly component is provided inside the housing 3, and a stabilization component is provided on the outer wall of the detection bracket 1.
[0035] The assembly and disassembly components include ball bearings 9, which facilitate the maintenance and replacement of sensor 5. The outer wall of ball bearing 9 is slidably connected to the inside of housing 3, enabling smooth sliding during assembly and disassembly. A placement block 10 is fixedly connected to the outer wall of the detection bracket 1, and the outer wall of housing 3 is slidably connected to the inside of placement block 10. It is made of aluminum alloy, which is lightweight and high-strength. Its interior provides a sliding track for housing 3. A housing 6 is fixedly connected to the inside of placement block 10. The housing 6 is made of stainless steel, which has good corrosion resistance and wear resistance. A limit post 8 is slidably connected inside the housing 6. A spring 7 is installed inside the housing 6. One end of the spring 7 is fixedly connected to the side wall of the limit post 8, and the other end of the spring 7 is fixedly connected to the inside of the housing 6. The side wall of the limit post 8 is rotatably connected to the outer wall of ball bearing 9, which improves the maintenance efficiency of sensor 5 and reduces equipment downtime caused by maintenance.
[0036] Specifically, when the gap detection device is working, sensor 5 monitors the gap data of brake 2 in real time. However, due to long-term operation in the harsh mining environment, the gap detection device will accumulate a lot of dust. Once this dust enters, it will affect the normal use of sensor 5, resulting in inaccurate detection data, which in turn threatens the safe operation of the braking device. When it is necessary to clean sensor 5, pull the placement block 10. The placement block 10 will drive the housing 6 to move. At the same time, the spring 7 will rebound, driving the limit post 8 to move, so that the outer wall of the ball 9 will be separated from the inside of the housing 3. The sensor 5 can be easily disassembled. After disassembly, the sensor 5 can be cleaned to remove accumulated impurities. When it is time to reassemble after cleaning, press the housing 3 to compress the spring 7, and then drive the limit post 8 to move horizontally, so that the ball 9 is stuck on the outer wall of the housing 3. This will quickly realize the reassembly of sensor 5, ensuring that it can continue to accurately detect the brake gap and ensure the stable operation of the mining machinery.
[0037] Reference Figure 1 , Figure 4 and Figure 5The stabilizing component includes a clamp 13, which is forged from a high-strength alloy. Its outer wall is precision-machined to form a dovetail groove structure, precisely fitting into the sliding groove 4 on the side wall of the detection bracket 1. The outer wall of the clamp 13 is slidably connected to the side wall of the detection bracket 1. An electric push rod 11 is fixedly connected inside the detection bracket 1. A connecting plate 12 is fixedly connected to the output end of the electric push rod 11. The connecting plate 12 is made of stainless steel, possessing good corrosion resistance and high strength. When the electric push rod 11 is activated, it can accurately transmit power through the connecting plate 12. The ground is transmitted to the clamp 13, driving it to make smooth displacement and providing reliable power support for subsequent clamping actions. The side wall of the connecting plate 12 is fixedly connected to one side of the clamp 13. A support frame 17 is fixedly connected inside the detection bracket 1. The support frame 17 is made of cast steel and has a complex and reasonable internal reinforcing rib structure, which can effectively distribute the force and enhance the overall load-bearing capacity. Two racks 14 and gears 15 are fixedly connected inside the support frame 17. The two racks 14 mesh with the gears 15. When one rack 14 moves under the drive of the electric push rod 11, the other rack 14 moves synchronously in the opposite direction through the transmission action of the gear 15, thereby realizing the synchronous action of the clamps 13 on both sides, ensuring more uniform and stable clamping of the brake 2, and further improving the accuracy of gap detection. The support frame 17 has a fixed block 16 fixedly connected to its side wall. The fixed block 16 is made of aluminum alloy, which is lightweight and has good heat dissipation performance. The outer wall of the fixed block 16 has undergone special surface treatment to form a smooth guide surface. The outer wall of the fixed block 16 has a fixed sliding block 18 fixedly connected to its side wall. The side wall of the sliding block 18 is fixedly connected to the other side of the clamp 13, providing additional guidance and support for the movement of the clamp 13, ensuring the straightness and stability of the movement of the clamp 13. The detection bracket 1 has a sliding groove 4 inside, and the outer wall of the clamp 13 is slidably connected to the inside of the sliding groove 4, so that the stabilizing component can work more reliably. This ensures that the gap detection device can accurately detect the brake gap in the complex working environment of mining machinery, providing a strong guarantee for the safe operation of the braking system.
[0038] Specifically, during the operation of the mining machinery, when it is necessary to clamp the brake 2, the operator activates the electric push rod 11. The electric push rod 11 is powerful and runs stably. After activation, it quickly drives the connecting plate 12 to move. The movement of the connecting plate 12 then drives the sliding block 18 to slide smoothly on the outer wall of the fixed block 16. The fixed block 16 provides a stable sliding track for the sliding block 18. At the same time, the sliding block 18 drives the rack 14 to slide. Since the rack 14 meshes with the gear 15, the sliding of one side of the rack 14 can drive the rotation of the other side of the rack 14. Consequently, the clamps 13 on both sides move towards the middle in sync. The clamps 13 move towards the middle to achieve stable clamping of the brake 2. This can effectively prevent the brake 2 from gap fluctuations caused by vibration or displacement during the operation of the mining machinery. In a stable environment, the sensor 5 can more accurately collect the brake gap data. The collected data can more realistically reflect the actual gap value, providing a reliable basis for the precise control and safe operation of the braking system.
[0039] Working principle: Dust accumulates in the gap detection device during long-term operation, causing sensor 5 to malfunction. Pulling the placement block 10 moves the housing 6, which in turn causes the spring 7 to rebound, displacing the limiting post 8 and detaching the outer wall of the ball bearing 9 from the housing 3, thus completing the disassembly of sensor 5. When reassembling sensor 5 after cleaning, pressing the housing 3 compresses the spring 7, which in turn moves the limiting post 8, causing the ball bearing 9 to lock onto the outer wall of the housing 3, thereby assembling sensor 5. After disassembling sensor 5, it can be thoroughly cleaned to remove impurities and ensure its normal operation.
[0040] When it is necessary to clamp the brake 2, the electric push rod 11 is activated, which drives the connecting plate 12 to move, and then drives the sliding block 18 to slide on the outer wall of the fixed block 16. At the same time, it drives the rack 14 to slide. Since the rack 14 meshes with the gear 15, it drives the other rack 14 to rotate, which in turn drives the clamps 13 on both sides to move towards the middle in sync. This can achieve clamping of the brake 2, which can avoid gap fluctuations caused by vibration or displacement of the brake 2, and make the data collected by the sensor 5 more accurately reflect the actual gap value.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
