Description

Technical Field

[0001] This utility model relates to the field of mine transport vehicle guide rail technology, specifically a mine transport vehicle guide rail structure that can be snapped together and installed. Background Technology

[0002] In mining operations, mine transport vehicle guide rails are a key infrastructure of the transportation system. The ease of installation, stability, and maintenance efficiency of these rails directly affect the mine's production efficiency and operating costs. Traditional mine transport vehicle guide rails are usually installed using welding methods, which have many drawbacks. Welding installation requires specialized welding equipment and technicians, and is not only cumbersome and time-consuming, but the high temperatures generated during welding can also cause guide rail deformation, affecting its straightness and accuracy, thereby reducing the operational stability and safety of the mine transport vehicle. Furthermore, it is not convenient to install and disassemble the guide rails during subsequent maintenance or replacement. With the continuous expansion of mining scale and the gradual increase in mining depth, mines have placed higher demands on the speed, flexibility, and adaptability of guide rail installation. Existing guide rail structures are difficult to adjust and replace quickly when facing complex terrain and changing geological conditions, and cannot meet the needs of efficient mining and safe production. Therefore, it is necessary to design a mine transport vehicle guide rail structure that can be installed by snap-fit ​​to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a mine transport vehicle guide rail structure that can be snapped into place, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mine transport vehicle guide rail structure that can be snapped on and installed, including a fixing plate, a first mounting mechanism being provided on the rear side of the fixing plate, and a second mounting mechanism being provided on the rear side of the first mounting mechanism;

[0005] The first installation mechanism includes a fixed platform, which is fixedly connected to the rear side of a fixed plate. A plug is inserted inside the fixed platform, and a guide rail body is fixedly connected to the top of the plug. The guide rail body is located on the top of the fixed platform, and a connecting block is fixedly connected to the bottom of the guide rail body. The connecting block is inserted inside the fixed platform, and a limiting shaft is engaged inside the plug. A limiting plate is fixedly connected to the right side of the limiting shaft, and a sliding rod is slidably connected inside the limiting plate. The sliding rod is fixedly connected inside the fixed platform, and a spring is sleeved around the sliding rod. A concave frame is inserted inside the connecting block, and a fixing pin is threaded inside the concave frame.

[0006] Preferably, the bottom of the guide rail body is in contact with the top of the fixed platform, and the limiting shaft is slidably connected inside the fixed platform, so that the insert can be engaged through the limiting shaft to play a limiting role.

[0007] Preferably, the left side of the spring is fixedly connected to the right side of the limiting plate, and the right side of the spring is fixedly connected to the fixed platform, so as to ensure the stability of the limiting plate and the limiting shaft under the action of the spring.

[0008] Preferably, the concave frame extends through the interior of the fixed platform, and the front side of the fixing pin is threaded into the interior of the fixed platform, which facilitates the limiting of the connection between the connecting block and the fixed platform under the action of the concave frame, further ensuring the stability of the guide rail body installation.

[0009] Preferably, the insert block, limiting shaft, slide rod, limiting plate and spring are provided in two sets. The two sets of insert blocks, limiting shafts, slide rods, limiting plates and springs are symmetrically distributed on the left and right sides of the bottom of the guide rail body, and the two sets of springs are made of titanium alloy material. By setting two sets, the stability of the guide rail body can be guaranteed.

[0010] Preferably, the second mounting mechanism includes a mounting base, which is fixedly connected to the rear side of the fixed platform. A rotating block is rotatably connected to the inner side of the mounting base. A rectangular frame is fixedly connected to the rear side of the rotating block. A connecting arm is slidably connected inside the rectangular frame. A limit pin is threadedly connected inside the connecting arm. A rotating shaft is rotatably connected inside the connecting arm. A fixed frame is rotatably connected to the outer periphery of the rotating shaft. A mounting plate is fixedly connected to the rear side of the fixed frame.

[0011] Preferably, the limiting pin passes through the inside of the rectangular frame, and the rectangular frame and the connecting arm are respectively provided with fixing grooves, and the two fixing grooves correspond to each other. The limiting pin is threaded into the fixing groove, which facilitates the stability between the rectangular frame and the connecting arm under the action of the limiting pin, and facilitates the movement of the connecting arm within the rectangular frame.

[0012] Compared with the prior art, this utility model provides a mine transport vehicle guide rail structure that can be snapped together, which has the following advantages:

[0013] 1. This snap-fit ​​mine transport vehicle guide rail structure, through its first installation mechanism, allows for installation of the guide rails used in the mine transport vehicle. First, the insert block and connecting block are inserted into the fixed platform. As the insert block moves downwards, it presses against the limiting shaft, causing the limiting shaft to slide the limiting plate around the slide rod and compress the spring. When the compression reaches a certain position, it releases the pressure on the limiting shaft, the spring returns to its original position, and the limiting plate and limiting shaft are re-engaged within the insert block, limiting the movement of the limiting shaft and ensuring the stability of the guide rail body. Simultaneously, the concave bracket is inserted into the connecting block. Furthermore, it runs through the interior of the fixed platform and is fixed to the concave frame by a limiting pin. The concave frame further ensures the stability between the guide rail body and the fixed platform, achieving a snap-fit ​​operation. No complicated tools or cumbersome operation steps are required, which greatly shortens the installation time. Two sets of symmetrically distributed plugs, limiting shafts and other components at the bottom of the guide rail body, as well as springs made of titanium alloy, give the guide rail structure excellent stability and durability. The titanium alloy spring has high strength and corrosion resistance, and can work stably for a long time in the harsh working conditions of mines, which are humid, dusty and vibrating, and is not prone to fatigue fracture.

[0014] 2. The snap-fit ​​mine transport vehicle guide rail structure, through the set second installation mechanism, allows the rotating block to rotate within a rectangular frame. Based on the positional distance between the mounting plate and the mine wall, the connecting arm moves within the rectangular frame, and the rotating shaft rotates within the rectangular frame. When the rear side of the mounting plate contacts the wall, the rectangular frame and connecting arm are fixed by the limit pin, ensuring stability between them and the mounting plate. The mounting plate is then fixed by external fixing equipment, further securing the fixing platform. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-6 This utility model provides a technical solution: a mine transport vehicle guide rail structure that can be snapped on and installed, including a fixing plate 1, a first mounting mechanism 2 provided on the rear side of the fixing plate 1, and a second mounting mechanism 3 provided on the rear side of the first mounting mechanism 2;

[0028] The first installation mechanism 2 includes a fixed platform 21, which is fixedly connected to the rear side of the fixed plate 1. A plug block 22 is inserted inside the fixed platform 21. A guide rail body 23 is fixedly connected to the top of the plug block 22. The guide rail body 23 is located on the top of the fixed platform 21. A connecting block 24 is fixedly connected to the bottom of the guide rail body 23. The connecting block 24 is inserted inside the fixed platform 21. A limiting shaft 25 is snapped inside the plug block 22. A limiting plate 27 is fixedly connected to the right side of the limiting shaft 25. A sliding rod 26 is slidably connected inside the limiting plate 27. The sliding rod 26 is fixedly connected inside the fixed platform 21. A spring 28 is sleeved around the sliding rod 26. A concave frame 29 is inserted inside the connecting block 24. A fixing pin 291 is threadedly connected inside the concave frame 29.

[0029] The bottom of the guide rail body 23 is in contact with the top of the fixed platform 21. The limiting shaft 25 is slidably connected inside the fixed platform 21, so that the insert block 22 can be engaged through the limiting shaft 25 to play a limiting role. The left side of the spring 28 is fixedly connected to the right side of the limiting plate 27, and the right side of the spring 28 is fixedly connected inside the fixed platform 21, so as to ensure the stability of the limiting plate 27 and the limiting shaft 25 under the action of the spring 28.

[0030] The concave frame 29 runs through the interior of the fixed platform 21, and the front thread of the fixing pin 291 is connected to the interior of the fixed platform 21. This facilitates the limiting of the connection between the connecting block 24 and the fixed platform 21 under the action of the concave frame 29, further ensuring the stability of the guide rail body 23 installation. Two sets of insert blocks 22, limiting shafts 25, slide rods 26, limiting plates 27, and springs 28 are provided. The two sets of insert blocks 22, limiting shafts 25, slide rods 26, limiting plates 27, and springs 28 are symmetrically distributed on the left and right sides of the bottom of the guide rail body 23. Both sets of springs 28 are made of titanium alloy, which makes it easy to ensure the stability of the guide rail body 23 by setting two sets.

[0031] Example 2

[0032] Please see Figure 1-6 Furthermore, based on Embodiment 1, the second mounting mechanism 3 includes a mounting base 31, which is fixedly connected to the rear side of the fixed platform 21. A rotating block 32 is rotatably connected to the inner side of the mounting base 31. A rectangular frame 33 is fixedly connected to the rear side of the rotating block 32. A connecting arm 34 is slidably connected inside the rectangular frame 33. A limit pin 35 is threadedly connected inside the connecting arm 34. A rotating shaft 36 is rotatably connected inside the connecting arm 34. A fixed frame 37 is rotatably connected to the outer periphery of the rotating shaft 36. A mounting plate 38 is fixedly connected to the rear side of the fixed frame 37. The limit pin 35 passes through the interior of the rectangular frame 33. Fixed grooves are respectively opened inside the rectangular frame 33 and the connecting arm 34, and the two fixed grooves correspond to each other. The limit pin 35 is threadedly connected to the fixed groove, which facilitates the stability between the rectangular frame 33 and the connecting arm 34 under the action of the limit pin 35, and facilitates the movement of the connecting arm 34 within the rectangular frame 33.

[0033] In actual operation, when this device is used and the guide rail used by the mining transport vehicle needs to be installed, firstly, insert block 22 and connecting block 24 are respectively inserted into the fixed platform 21. When insert block 22 moves downward, it will squeeze the limiting shaft 25 and cause the limiting shaft 25 to drive the limiting plate 27 to slide around the slide rod 26 and squeeze the spring 28. When squeezed to a certain position, the compression of the limiting shaft 25 will be released and the spring 28 will return to its original position, so that the limiting plate 27 and the limiting shaft 25 can be re-clamped into the insert block 22 to limit the limiting shaft 25 and ensure the stability of the guide rail body 23. At the same time, the concave frame 29 is inserted into the connecting block 24 and passes through the fixed platform 21. The concave frame 29 is fixed by the limiting pin 35, which further ensures the stability between the guide rail body 23 and the fixed platform 21 under the action of the concave frame 29, realizing the clamping work. No complicated tools and cumbersome operation steps are required, which greatly shortens the installation time.

[0034] Two sets of symmetrically distributed components such as the insert block 22 and the limiting shaft 25 at the bottom of the guide rail body 23, as well as the spring 28 made of titanium alloy, give the guide rail structure excellent stability and durability. The titanium alloy spring 28 has high strength and corrosion resistance, and can work stably for a long time in the harsh working conditions of mines that are humid, dusty and vibrating, and is not prone to fatigue fracture.

[0035] When the guide rail body 23 is fixed to the top of the fixed platform 21 under the action of the limiting shaft 25 and the concave frame 29, the transport vehicle needs to use two sets of guide rail bodies 23. According to the distance between the two sets of guide rail bodies 23, the fixed plate 1 is fixed by external anchor bolts or other fixing equipment, and the distance between the two guide rail bodies 23 meets the standard. The rotating block 32 can rotate within the rectangular frame 33. According to the position distance between the mounting plate 38 and the inner wall of the mine, the connecting arm 34 moves within the rectangular frame 33, and the rotating shaft 36 rotates within the rectangular frame 33. When the rear side of the mounting plate 38 contacts the wall, the rectangular frame 33 and the connecting arm 34 can be fixed by the limiting pin 35 to ensure the stability between the two and the stability of the mounting plate 38. The mounting plate 38 is fixed by external fixing equipment, which can further fix the fixed platform 21. By fixing the fixed platform 21 in multiple dimensions, the stability of the guide rail body 23 is ensured.

[0036] When the guide rail body 23 needs to be disassembled and maintained, simply remove the fixing pin 291 and the concave bracket 29, and pull the limiting plate 27 from the front of the fixing platform 21 to move the limiting shaft 25 away from the inside of the insert block 22.
