Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a curved track that is easy to assemble and disassemble. Background Art

[0002] A mine curved track typically refers to a track structure used in a mining transportation system to achieve automatic unloading of mine cars. This structure allows mine cars to tip over and unload themselves by their own weight and the guiding effect of the curved track when passing over a specially designed curved track.

[0003] Curved rails are usually made of steel frames. Once manufactured, the height and length of the curved rails are fixed. During installation, the specifications of the curved rails cannot be adjusted according to the actual conditions of the mining scene. The installation site needs to be excavated and adjusted to adapt to the position and height of the mine car moving track, resulting in low flexibility and practicality when using curved rails. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the height and length of the curved rail after manufacturing are fixed, and the specifications of the curved rail cannot be adjusted according to the actual situation of the mining scene during installation. It is necessary to excavate and adjust the installation site to adapt to the position and height of the mine car moving track, resulting in low flexibility and practicality of the curved rail during use. Therefore, this invention proposes a curved rail that is easy to assemble and disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a curved rail that is easy to assemble and disassemble, comprising a base plate, the outer surface of which is provided with a plurality of mounting holes, a groove rod fixedly connected to the top of the base plate, a slide rod slidably connected to the inner wall of the groove rod, a curved rail rod fixedly connected to the top of the slide rod, an adjustment device provided on the outer surface of the slide rod, the adjustment device comprising a connecting plate, one side of the connecting plate being fixedly connected to one side of each slide rod, a sliding groove being provided on one side of the groove rod, the connection between the outer surface of the connecting plate and the outer surface of the slide rod sliding on the inner wall of the sliding groove, a first screw being rotatably connected to one side of the base plate, the outer surface of the first screw being threadedly connected to the inner wall of the connecting plate, a sliding plate slidably connected to one end of the curved rail rod, a support plate fixedly connected to the top of the sliding plate, a rectangular groove being provided on one side of the curved rail rod, a second screw being fixedly connected to one side of the sliding plate, the outer surface of the second screw sliding on the inner wall of the rectangular groove, and a threaded ring being threadedly connected to the outer surface of the second screw.

[0006] The effect achieved by the above components is as follows: By setting the first screw, when the height position of the curved rail needs to be adjusted during installation, the first screw can be rotated on one side of the base plate to control the connecting plate to move up and down on the outer surface of the first screw, thereby driving the sliding rod to slide up and down on the inner wall of the groove rod to adjust and fix the height position of the curved rail rod. Then, the sliding plate is pushed at one end of the curved rail rod to slide on the inner wall of the curved rail rod to adjust the position of the support plate on the outer surface of the curved rail rod, so that one end of the support plate touches the ground. At the same time, the second screw will slide on the inner wall of the rectangular groove. Rotating the threaded ring on the outer surface of the second screw causes the threaded ring to move towards the curved rail rod on the outer surface of the second screw, pressing one side of the threaded ring against the outer surface of the curved rail rod to fix the position of the sliding plate inside the curved rail rod and the position of the support plate on the outer surface of the curved rail rod, thus completing the height adjustment of the curved rail.

[0007] Preferably, a gasket is fixedly connected to one side of the threaded ring, and the gasket is made of rubber.

[0008] The effect achieved by the above components is that when the threaded ring is rotated and the side of the threaded ring with the rubber gasket is pressed against the outer surface of the curved rail rod, it is more stable and less prone to slippage when fixing the position of the sliding plate and the curved rail rod.

[0009] Preferably, a stop block is fixedly connected to the end of the second screw away from the sliding plate, and the length of the stop block is greater than the diameter of the second screw.

[0010] The effect achieved by the above components is that by setting the stop block, the movement range of the threaded ring on the outer surface of the second screw can be limited, preventing the threaded ring from detaching from the surface of the second screw when it moves outward.

[0011] Preferably, a disc is fixedly connected to the top end of the first screw, and a handle is rotatably connected to the top end of the disc.

[0012] The effect achieved by the above components is that holding the outer surface of the grip lever makes it easier to push the disc to control the rotation of the first screw and adjust the height position of the curved rail rod.

[0013] Preferably, two cylinders are fixedly connected to the top of the base plate, and two round rods are fixedly connected to the bottom of the connecting plate, with the outer surface of the round rods sliding on the inner wall of the cylinders.

[0014] The effect achieved by the above components is that when the first screw is rotated to control the up and down movement of the connecting plate, the two round rods will slide on the inner walls of the two cylinders, further restricting the angle between the connecting plate and the bottom plate, and between the groove rod and the slide rod, so as to avoid shaking when the slide rod moves as much as possible.

[0015] Preferably, the bottom end of the connecting plate is fixedly connected to two inclined rods, and the ends of the two inclined rods that are close to each other are fixedly connected to a ring, the inner wall of the ring sliding on the outer surface of the first screw.

[0016] The effect achieved by the above components is that when the first screw is rotated to control the up and down movement of the connecting plate, the ring will slide up and down on the outer surface of the first screw. The two diagonal rods can support the lower ends of the connecting plate, thus minimizing the risk of the connecting plate tilting.

[0017] Preferably, the outer surface of the slide bar is provided with a reinforcing device, the reinforcing device includes a plug rod, one end of which is rotatably connected to a rotating rod, and the outer surface of the slide bar is provided with a plurality of slots, which are linearly distributed on the outer surface of the slide bar.

[0018] The effect achieved by the above components is as follows: After the height of the curved rail rod is adjusted by the adjustment device during installation, one end of the rotating rod can be inserted into the slot on one side of the slide rod and the rotating rod can be moved into the slide rod at the other end. Then, the insertion rod is pushed to rotate so that the insertion rod is parallel to the rotating rod and the insertion rod is inserted into the slide rod at the end away from the rotating rod. The rotating rod and the slide rod support the interior of the slide rod, so as to avoid the curved rail rod from shifting due to gravity and affecting the stability of the curved rail during use.

[0019] Preferably, the insertion rod and the rotating rod are made of stainless steel that can be attracted by a magnet, and a positioning block is fixedly connected to one side of the rotating rod. The positioning block is a magnetic block with a certain magnetism.

[0020] The effect achieved by the above components is that, without the reinforcement device, the rotating rod can be pushed to rotate in the direction of the insertion rod so that the magnetic positioning block on one side of the rotating rod contacts the outer surface of the insertion rod and is magnetically attracted to the outer surface of the insertion rod, so that the rotating rod and the insertion rod are folded, making them easy to carry or store.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting an adjustment device, when the height position of the curved rail needs to be adjusted according to requirements, the first screw is rotated to control the connecting plate to drive the sliding rod and the curved rail rod to move up and down and fix them. By pushing the sliding plate to adjust the position of the support plate so that one end of the support plate contacts the ground, the height position of the curved rail rod can be adjusted and fixed, thus improving the convenience and flexibility of using the curved rail.

[0030] Example 1, such as Figure 1-5As shown, a conveniently assembled and disassembled curved rail includes a base plate 1. The outer surface of the base plate 1 has several mounting holes 4. A grooved rod 5 is fixedly connected to the top of the base plate 1. A sliding rod 6 is slidably connected to the inner wall of the grooved rod 5. A curved rail rod 7 is fixedly connected to the top of the sliding rod 6. An adjustment device 2 is provided on the outer surface of the sliding rod 6. The adjustment device 2 includes a connecting plate 22. One side of the connecting plate 22 is fixedly connected to one side of each sliding rod 6. A sliding groove 21 is provided on one side of the grooved rod 5. The connection between the outer surface of the connecting plate 22 and the outer surface of the sliding rod 6 slides on the inner wall of the sliding groove 21. A first... The first screw 23 has its outer surface threadedly connected to the inner wall of the connecting plate 22. A sliding plate 24 is slidably connected to one end of the curved rail rod 7, and a support plate 25 is fixedly connected to the top of the sliding plate 24. A rectangular groove 26 is formed on one side of the curved rail rod 7, and a second screw 27 is fixedly connected to one side of the sliding plate 24. The outer surface of the second screw 27 slides on the inner wall of the rectangular groove 26, and a threaded ring 28 is threadedly connected to its outer surface. By setting the first screw 23, when adjusting the height of the curved rail rod 7 during installation, the first screw 23 can be rotated on one side of the base plate 1. The control plate 22 moves up and down on the outer surface of the first screw 23, causing the slide bar 6 to slide up and down on the inner wall of the groove bar 5 to adjust and fix the height position of the curved rail bar 7. Then, the sliding plate 24 is pushed at one end of the curved rail bar 7 to slide on the inner wall of the curved rail bar 7 to adjust the position of the support plate 25 on the outer surface of the curved rail bar 7, so that one end of the support plate 25 touches the ground. At the same time, the second screw 27 slides on the inner wall of the rectangular groove 26. The threaded ring 28 on the outer surface of the second screw 27 is rotated to move the threaded ring 28 towards the curved rail bar 7 on the outer surface of the second screw 27, pressing one side of the threaded ring 28 against the curved rail bar 7. The outer surface of the rail rod 7 is fixed to the position of the sliding plate 24 inside the curved rail rod 7 and the position of the support plate 25 on the outer surface of the curved rail rod 7, thus completing the height adjustment of the curved rail. By setting the adjustment device 2, when the height position of the curved rail needs to be adjusted according to the requirements, the first screw 23 is rotated to control the connecting plate 22 to drive the sliding rod 6 and the curved rail rod 7 to move up and down and fix them. By pushing the sliding plate 24 to adjust the position of the support plate 25 so that one end of the support plate 25 contacts the ground, the height position of the curved rail rod 7 can be adjusted and fixed, improving the convenience and flexibility when using the curved rail.

[0031] Reference Figure 2-5As shown in this embodiment: a gasket 29 is fixedly connected to one side of the threaded ring 28. The gasket 29 is made of rubber. Rotating the threaded ring 28 presses the side of the threaded ring 28 with the rubber gasket 29 against the outer surface of the curved rail rod 7 to fix the position of the sliding plate 24 and the curved rail rod 7, making it more stable and less prone to slippage. A stop block 210 is fixedly connected to the end of the second screw 27 away from the sliding plate 24. The length of the stop block 210 is greater than the diameter of the second screw 27. By setting the stop block 210, the movement range of the threaded ring 28 on the outer surface of the second screw 27 can be limited, preventing the threaded ring 28 from detaching from the surface of the second screw 27 when it moves outward.

[0032] Reference Figure 2-5 As shown in this embodiment: a disc 211 is fixedly connected to the top of the first screw 23, and a handle 212 is rotatably connected to the top of the disc 211. Holding the handle 212 on its outer surface makes it easier to push the disc 211 to control the rotation of the first screw 23 and adjust the height of the curved rail rod 7. Two cylinders 213 are fixedly connected to the top of the base plate 1, and two round rods 214 are fixedly connected to the bottom of the connecting plate 22. The outer surface of the round rods 214 slides on the inner wall of the cylinders 213. When the first screw 23 is rotated to control the connecting plate 22 to move up and down, the two round rods 214 will slide on the inner wall of the two cylinders 213. The angle between the connecting plate 22 and the base plate 1, and between the groove rod 5 and the slide rod 6, is further restricted to minimize the wobbling of the slide rod 6 during movement. Two inclined rods 215 are fixedly connected to the bottom end of the connecting plate 22. A ring 216 is fixedly connected to one end of the two inclined rods 215 that is close to each other. The inner wall of the ring 216 slides on the outer surface of the first screw 23. When the first screw 23 is rotated to control the connecting plate 22 to move up and down, the ring 216 will slide up and down on the outer surface of the first screw 23. The two inclined rods 215 can support the lower ends of the connecting plate 22 to minimize the skew of the angle of the connecting plate 22.

[0033] Reference Figure 1 , Figure 2 and Figure 6As shown in this embodiment: a reinforcing device 3 is provided on the outer surface of the slide rod 6. The reinforcing device 3 includes an insert rod 32, one end of which is rotatably connected to a rotating rod 33. Several slots 31 are provided on the outer surface of the slide rod 6. The slots 31 are linearly distributed on the outer surface of the slide rod 6. When installing the curved rail, after adjusting the height of the curved rail rod 7 by adjusting the adjusting device 2, one end of the rotating rod 33 can be inserted into the slot 31 on one side of the slide rod 6 and the rotating rod 33 can be moved into the slide rod 6 at the other end. Then, the insert rod 32 is pushed to rotate so that the insert rod 32 is parallel to the rotating rod 33 and the insert rod 32 is inserted into the slide rod 6 at the end away from the rotating rod 33. The section uses a rotating rod 33 and a sliding rod 6 to support the interior of the sliding rod 6, minimizing the risk of displacement of the curved rail rod 7 due to gravity, which would affect the stability of the curved rail during use. The insertion rod 32 and the rotating rod 33 are made of stainless steel that can be attracted by magnets. A positioning block 34 is fixedly connected to one side of the rotating rod 33. The positioning block 34 is a magnetic block with a certain degree of magnetism. When the reinforcement device 3 is not used, the rotating rod 33 can be pushed to rotate towards the insertion rod 32, so that the magnetic positioning block 34 on one side of the rotating rod 33 contacts the outer surface of the insertion rod 32 and is magnetically attracted to the outer surface of the insertion rod 32, making the rotating rod 33 and the insertion rod 32 foldable for easy carrying or storage.

[0034] Working principle: When installing the curved rail, place the base plate 1 on one side of the mine car track. Use anchor bolts or other tools to connect the base plate 1 to the ground through the mounting holes 4 on the outer surface of the base plate 1. When it is necessary to adjust the height of the curved rail rod 7, the first screw 23 can be rotated on one side of the base plate 1 to control the connecting plate 22 to move up and down on the outer surface of the first screw 23, causing the sliding rod 6 to slide up and down on the inner wall of the groove rod 5 to adjust and fix the height of the curved rail rod 7. Then, push the sliding plate 24 at one end of the curved rail rod 7 to slide on the inner wall of the curved rail rod 7 to adjust the position of the support plate 25 on the outer surface of the curved rail rod 7, so that one end of the support plate 25 touches the ground. At the same time, the second screw 27 will slide on the inner wall of the rectangular groove 26. Rotate the threaded ring 28 on the outer surface of the second screw 27 to move the threaded ring 28 in the direction of the curved rail rod 7 on the outer surface of the second screw 27. One side of the ring 28 is pressed against the outer surface of the curved rail rod 7 to fix the position of the sliding plate 24 inside the curved rail rod 7 and the position of the support plate 25 on the outer surface of the curved rail rod 7. This completes the height adjustment of the curved rail. After the adjustment is completed, one end of the rotating rod 33 can be inserted into the slot 31 on one side of the slide rod 6 and the rotating rod 33 can be moved in the slot 31 to the slide rod 6 at the other end. Then push the insertion rod 32 to rotate so that the insertion rod 32 is parallel to the rotating rod 33 and the insertion rod 32 is inserted into the slide rod 6 at the end away from the rotating rod 33. The rotating rod 33 and the slide rod 6 support the interior of the slide rod 6. When removing the curved rail, remove the anchor nails at the mounting holes (4) on the outer surface of the base plate (1). Then adjust the distance between the curved rail rod (7) and the base plate (1) through the adjustment device (2) to reduce the overall size of the curved rail, which is convenient for disassembly and transportation.
