Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection device technology, and in particular to a detection device for brake shoe clearance protection of disc brake devices. Background Technology
[0002] During the operation of disc brake systems, accurate monitoring and protection of brake shoe clearance are crucial for the performance and safety of the braking system. Brake shoe clearance directly affects the braking response time, braking force, and braking stability. If the brake shoe clearance is too large, it will lead to a longer braking stroke and a delayed braking time, which may even cause brake failure in severe cases, endangering equipment and personnel safety. If the brake shoe clearance is too small, it will easily cause excessive friction between the brake shoe and the brake disc, which will not only accelerate the wear of the brake shoe and brake disc and reduce their service life, but may also generate too much heat due to friction, causing thermal failure of the braking system. The brake shoe clearance protection and detection device aims to monitor the brake shoe clearance in real time and issue an alarm or take corresponding adjustment measures in a timely manner when the clearance is abnormal, so as to ensure the reliable operation of the disc brake system.
[0003] Traditional brake shoe gap detection devices typically consist of a simple displacement detection element and a basic signal processing unit. The displacement detection element is installed close to the brake shoe and is linked to the displacement of the brake shoe, thereby driving the brush of the potentiometer to move, changing the resistance value of the potentiometer, and converting the displacement of the brake shoe into an electrical signal.
[0004] However, traditional brake shoe clearance protection and detection devices have serious shortcomings in protecting displacement sensors. Due to the lack of a complete protective structure, displacement sensors are easily affected by external environmental factors. In some industrial production scenarios, there are a lot of dust, oil, moisture, etc. These impurities can easily penetrate into the sensor, affecting its measurement accuracy and service life. In addition, during equipment operation, the sensor is easily damaged by accidental collisions or vibrations. Once the sensor fails, the entire brake shoe clearance detection system will not work properly. Therefore, a brake shoe clearance protection and detection device for disc brake devices is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a brake shoe gap protection and detection device for disc brake devices, which aims to improve the problem that displacement sensors in the prior art are easily affected by external environmental factors and are easily damaged by accidental collisions or vibrations during equipment operation.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0030] 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.
[0031] Reference Figure 1-Figure 3 The present invention provides an embodiment of a brake shoe gap protection and detection device for a disc brake system, comprising a detection disc 1 and a brake head 2. The gap between the detection disc 1 and the brake head 2 is 1-2mm, which is the standard gap range when the disc brake system is working normally. A protective shell 3 is fixedly connected to the outer wall of the brake head 2, which provides protection for the internal displacement sensor 4. The displacement sensor 4 is installed inside the protective shell 3 for accurately measuring the gap between the brake shoe and the brake disc. A connector 5 is fixedly connected inside the displacement sensor 4. A sliding groove 6 is opened inside the protective shell 3, and the connector 5 is slidably connected inside the sliding groove 6. A protective component is provided on one side of the protective shell 3, and a limit component is provided inside the protective shell 3.
[0032] The protective component includes a protective cover 7, which is located on one side of the protective shell 3 and can effectively prevent dust and moisture from entering the interior of the protective shell 3. The protective cover 7 and the protective shell 3 are in close contact. A connecting block 8 is fixedly connected to one side of the protective cover 7, and a sleeve 9 is fixedly connected to one side of the protective shell 3. The connecting block 8 and the sleeve 9 are fitted together. Threaded posts 10 are slidably connected inside both the connecting block 8 and the sleeve 9. Nuts 11 are threadedly connected to the outer wall of the threaded posts 10, and a retaining ring 12 is fixedly connected to one end of the threaded posts 10.
[0033] Specifically, during the installation of this gap protection detection device, the displacement sensor 4 is first placed into the protective shell 3 on the outer wall of the gate head 2. At this time, the connector 5 on one side of the displacement sensor 4 slides into the groove 6 designed inside the protective shell 3. The protective shell 3 is designed to provide a secure housing space for the displacement sensor 4 while preventing any potential damage to the sensor from the external environment. Next, the protective cover 7 is attached to one side of the protective shell 3. The protective cover 7 not only provides protection but also effectively isolates external dust, moisture, and other harmful substances. During installation, the connecting block 8 on one side of the protective cover 7 slides into the sleeve 9 on one side of the protective cover 7, making the installation of the protective cover 7 more secure. The connection between the connecting block 8 and the sleeve 9 is simple and efficient. The sliding fit ensures the stability of the protective cover 7. The installer inserts the threaded post 10 into the connecting block 8 and the sleeve 9 and rotates it to tighten the nut 11 on the outer wall of the threaded post 10. This ensures a tight connection between the protective cover 7 and the protective shell 3, effectively preventing loosening or damage in harsh working environments. The protective cover 7 tightly closes the protective shell 3, providing a sealed and robust protective space for the displacement sensor 4. After installation, the displacement sensor 4 is tightly connected to the gate head 2 through the connector 5, ensuring the stable operation of the displacement sensor 4 and guaranteeing its accurate measurement and normal operation.
[0034] Reference Figure 3 and Figure 4 The limiting component includes a fixed frame 14 and a support shaft 15. The outer wall of the fixed frame 14 is fixedly connected to the inside of the protective shell 3, which serves to support the entire limiting component and ensure the stable positioning of other components. The outer wall of the support shaft 15 is fixedly connected to the inside of the fixed frame 14. A transparent plate 13 is provided inside the protective cover 7. A fixed block 19 is fixedly connected to the top of the fixed frame 14. A limiting block 16 is rotatably connected to the outer wall of the support shaft 15. The limiting block 16 is in contact with the displacement sensor 4. A sliding column 17 is slidably connected inside the fixed frame 14. One end of the sliding column 17 is in contact with one side of the limiting block 16, and the sliding part is in contact with one side of the limiting block 16. The other end is connected through a handle 18. The other end of the sliding column 17 is fixedly connected to the handle 18. A spring 20 is provided on one side of the fixed block 19. One end of the spring 20 is fixedly connected to one side of the fixed block 19, and the other end of the spring 20 is fixedly connected to one side of the limiting block 16. When the equipment is adjusted, the spring 20 can restore the original position of the limiting block 16 to avoid jamming or damage to the parts.
[0035] Specifically, when the displacement sensor 4 needs to be disassembled and maintained, when the displacement sensor 4 slides into the protective shell 3, the displacement sensor 4 will touch the limiting block 16 inside the protective shell 3. When the displacement sensor 4 contacts the limiting block 16, the limiting block 16 will rotate on the outer wall of the support shaft 15 due to the force. During the rotation, the limiting block 16 will simultaneously squeeze the spring 20 located on one side, causing the spring 20 to contract. The function of the spring 20 is to provide a buffer and rebound force to ensure that the displacement sensor 4 can smoothly enter the protective shell 3 and avoid damage to the sensor due to hard contact. After the displacement sensor 4 is completely placed into the protective shell 3, the spring 20 will quickly return to its original shape through the force relief effect and drive the limiting block 16 to reset. The limiting block 16 will lock onto the outer wall of the displacement sensor 4 on one side, firmly fixing it inside the protective shell 3, thus completing the installation. During disassembly, the protective cover 7 needs to be removed from one side of the protective shell 3 first. After disassembly, the sliding column 17 can slide freely inside the fixed frame 14. The design of the sliding column 17 facilitates quick adjustment of the position of the limiting block 16, enabling it to rotate effectively. One side of the limiting block 16 is pushed, causing the limiting block 16 to rotate on the outer wall of the support shaft 15. At this time, the rotation of the limiting block 16 releases the displacement sensor 4, thus completing the disassembly. This ensures timely maintenance and replacement of the displacement sensor 4, improving the reliability and long-term stability of the system.
[0036] Working Principle: When using this gap protection detection device, if the displacement sensor 4 needs to be placed, first place the displacement sensor 4 into the protective shell 3 on the outer wall of the gate head 2. Simultaneously, the connector 5 on one side of the displacement sensor 4 slides into the groove 6 inside the protective shell 3. Then, attach the protective cover 7 to one side of the protective shell 3, and simultaneously, the connecting block 8 on one side of the protective cover 7 slides into the sleeve 9 on one side of the protective cover 7. At this point, insert the threaded post 10 into the connecting block 8 and the sleeve 9, and tighten the nut 11 on the outer wall of the threaded post 10 to fix it, so that the protective cover 7 closes the protective shell 3. Then, the gate head 2 and the displacement sensor 4 are connected through the connector 5, thus achieving effective protection for the displacement sensor 4. When the displacement sensor 4 needs to be disassembled and maintained, when the displacement sensor 4 slides into the protective shell 3... During the process, the displacement sensor 4 will contact the limiting block 16 inside the protective shell 3, causing the limiting block 16 to rotate on the outer wall of the support shaft 15 under force. At the same time, the limiting block 16 will squeeze the spring 20 on one side, causing it to contract. When the displacement sensor 4 is completely inserted into the protective shell 3, the spring 20 will release the force and rebound, thereby driving the limiting block 16 to reset, so that one side of the limiting block 16 is stuck on the outer wall of the displacement sensor 4 and fixes it inside the protective shell 3, completing the installation. When disassembling, first remove the protective cover 7 from one side of the protective shell 3, then push the sliding column 17 to slide inside the fixing frame 14, and push one side of the limiting block 16, causing the limiting block 16 to rotate on the outer wall of the support shaft 15, thereby releasing the displacement sensor 4, thus achieving the effect of facilitating the disassembly and fixation of the displacement sensor 4.
