Detailed Implementation
[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example
[0018] like Figures 1 to 4 As shown, this utility model provides a protective device for preventing derailment of mine car tracks in coal mines. First, there is a support frame 11, which acts as the skeleton of the device, providing a support structure for the entire device. The support frame 11 provides a reliable foundation for the installation of subsequent components, allowing the device to be stably erected between the mine car and the track, thus improving the overall stability of the device and ensuring that it does not easily shake or shift in the complex underground working environment.
[0019] At the top of the support frame 11, a connector is installed for connecting to the mine car and reducing vibration damage. This connector consists of a mounting plate 12 and an adjusting column 13. The adjusting column 13 and the adjusting sleeve 14 are connected by a thread. The device can adjust the connection gap by rotating the adjusting rod 15 to drive the adjusting column 13 to rotate inside the adjusting sleeve 14. This allows the device to adapt to the structural characteristics of the bottom of different models of mine cars, improving the versatility of the device. The top of the mounting plate 12 is connected to the bottom of the mine car, and the bottom is rotatably connected to the adjusting column 13. A certain sliding space is provided at the rotation point, which gives the device good buffering ability and alleviates the damage caused by the vibration generated during the operation of the mine car to the device and the mine car itself.
[0020] like Figure 2 As shown, two sets of upper clamping components for installation on the I-beam rail are symmetrically arranged on the support frame 11. The upper clamping components include a rotating rod 16, a rotating sleeve 17, and a rotating cylinder 18. The rotating cylinder 18 is fitted onto the rotating rod 16 and fixed to one end. The device is rotatably connected to the four sets of second mounting slots symmetrically opened on the support frame 11 at both ends of the upper clamping components, realizing convenient installation and fixation on the I-beam rail. In this way, the device can fit the rail, improve the installation stability on the rail, and enhance the ability of the device to be fixed on the rail.
[0021] The support frame 11 has two sets of symmetrical first mounting slots, and each first mounting slot is equipped with an L-shaped plate 19. The presence of the L-shaped plate 19 provides an ideal carrier for the installation of other components. Through its reasonable layout, the device can integrate various functional components in an orderly manner, improve the scientific and rational nature of the device's structural layout, and make the entire device's architecture more compact and orderly.
[0022] like Figure 3 As shown, one end of the L-shaped plate 19 is equipped with a fixing component for assisting quick installation. The fixing component consists of a fixing member and a first self-locking member. The fixing member includes a fixing cylinder 21 and a sliding baffle 22. A matching fixing groove is provided in the first mounting groove. The fixing cylinder 21 passes through the L-shaped plate 19 and is inserted into the fixing groove. The sliding baffle 22 is slidably connected to the fixing cylinder 21. Two sets of third mounting grooves symmetrically opened on the fixing cylinder 21 are equipped with magnetic suction plates 23. The magnetic suction plates 23 utilize their own magnetism to attract the metal parts of the support frame 11 during installation, assisting the fixing cylinder 21 in quick positioning, simplifying the installation process, and improving installation efficiency. The magnetic suction plates 23 can be neodymium iron boron permanent magnet magnetic suction plates.
[0023] The first self-locking component includes two sets of conical first locking plates 24 and two sets of first springs 25. The sliding baffle 22 has two sets of fourth mounting slots. The first locking plates 24 slide in the fourth mounting slots. The two ends of the first springs 25 are connected to the two sets of first locking plates 24 respectively. The fourth mounting slot is also provided with a first limiting slot for assisting in fixing the first locking plates 24. When the fixing cylinder 21 is inserted into the fixing slot, under the elastic force of the first springs 25, the conical first locking plates 24 expand outward. Their conical structure can better wedge into the first limiting slot to form a locking effect. Even if the device is subjected to severe vibration or external impact, the first locking plates 24 can be tightly locked to prevent the L-shaped plate 19 from loosening and falling off, thus improving the device's ability to maintain structural stability.
[0024] like Figures 1 to 4 As shown, a side clamping component is installed at the other end of the L-shaped plate 19. The side clamping component consists of a fixed block 26, five sets of second rotating wheels 27, and a second self-locking component. The fifth mounting slot on the L-shaped plate 19 is used to install the fixed block 26, and the five sets of second rotating wheels 27 are installed on the fixed block 26. During the operation of the mine car, the second rotating wheels 27 contact the side of the track and dynamically clamp and guide the side of the mine car track through rolling friction. This not only reduces the friction loss between the mine car and the track, but also better constrains the running trajectory of the mine car, so that the mine car always travels safely along the track, thus improving the protection effect of the device against derailment of the mine car.
[0025] The second self-locking component includes a fixed shell 28 and a limiting shell 29. Two sets of slots are symmetrically arranged on the top of the fixed shell 28, and two sets of posts are symmetrically arranged on the bottom of the limiting shell 29. The two sets of slots pass through the L-shaped plate 19 and the fixed block 26 and are connected to the two sets of posts. The posts are also equipped with a second self-locking component consisting of a second spring 31 and two sets of conical second plates 32. Two sets of sliding grooves are opened on the posts, and the second plates 32 are slidably connected to the sliding grooves. The two ends of the second spring 31 are respectively connected to the two sets of second plates 32. The slots are provided with second limiting grooves for assisting in fixing the second plates 32. When the fixed shell 28 and the limiting shell 29 are connected, the second spring 31 pushes the conical second plates 32 into the second limiting grooves. Even in long-term, high-intensity working environments, the side clamping component can maintain reliable clamping performance, which improves the durability of the device under complex working conditions and provides a long-term and stable guarantee for the safe operation of the mine car.
[0026] Multiple sets of first support frames 33 are also installed on the L-shaped plate 19. Each first support frame 33 is equipped with a first roller 34 for fixing the bottom of the auxiliary device. The first support frame 33 provides stable support for the first roller 34. During the installation of the device, the first roller 34 can roll along the track, which makes it convenient for the operator to adjust the position of the device and makes the installation more convenient. During the use of the device, the first roller 34 shares the weight, reduces the friction between the device and the track, and improves the convenience of the device in the installation and use process.
[0027] The specific usage and function of this embodiment are as follows: Connect the mounting plate 12 of the top connector of the support frame 11 to the bottom of the mine car. By rotating the adjusting rod 15, the adjusting column 13 is driven to rotate in the adjusting sleeve 14. According to the specific structure and installation requirements of the bottom of the mine car, the connection distance and angle between the mounting plate 12 and the bottom of the mine car are adjusted. This operation enables the device to be adapted to different models of mine cars.
[0028] The two ends of the rotating rod 16 of the upper clamping member are respectively rotatably connected to the four sets of second mounting slots symmetrically opened on the support frame 11, so that the rotating cylinder 18 is fitted onto one end of the rotating rod 16. In this way, the device can be easily installed on the I-beam rail, improving the stability of the device on the rail, just like building a connecting bridge between the device and the rail.
[0029] After installing the side clamping component, the fixing shell 28 and the limiting shell 29 of the side clamping component are connected to the clamping post through the slot. The second spring 31 on the clamping post pushes the conical second clamping plate 32 into the second limiting groove in the slot, further reinforcing the connection of each component of the side clamping component. This ensures that the side clamping component always maintains reliable clamping performance under harsh and complex working conditions, providing a lasting guarantee for the safe operation of the mine car.
[0030] During the installation of the device, the first roller 34 of the first support frame 33 on the L-shaped plate 19 can roll along the track, which makes it convenient for operators to adjust the position of the device and reduce the difficulty of installation. When the device is in use, the first roller 34 shares part of the weight of the device and reduces the friction between the device and the track.
[0031] When installing the L-shaped plate 19, the fixing cylinder 21 is inserted through the L-shaped plate 19 and into the fixing groove in the first mounting groove. The magnetic attraction plate 23 on the fixing cylinder 21 is used to attract the metal part of the support frame 11 to assist in quick positioning. Then, the sliding baffle 22 slides in the fixing cylinder 21. Under the action of the elastic force of the first spring 25, the conical first locking plate 24 expands outward and weds into the first limiting groove in the fourth mounting groove to lock the L-shaped plate 19 and prevent it from loosening.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
