Description

Technical Field

[0001] This utility model relates to the field of mining transportation technology, and in particular to a mine transportation anti-runaway device. Background Technology

[0002] Mining transportation is a crucial link in mining production, responsible for transferring mined ore and waste between underground and the surface. It involves equipment such as dump trucks, railcars, and belt conveyors. Due to the many steep slopes and curves in the working environment, the risk of vehicles slipping is high, which can easily lead to safety accidents. Anti-slipping equipment is the core of ensuring transportation safety. By physically blocking or monitoring the vehicle status in real time, it can prevent slippage in time and build a safety line for mining transportation.

[0003] Among the existing anti-runaway equipment used in mining transportation, the mainstream devices such as car stoppers and car barriers mostly adopt a single-sided snap-fit ​​limiting structure. They are usually set with a liftable wedge-shaped block or rotating baffle on one side of the track, which achieves the limiting by pressing against the side of the mine car wheel. However, this design has obvious defects. When the center of gravity of the mine car loaded with material shifts, the track has a lateral slope, or it is subjected to heavy load impact, the single-sided constraint is difficult to balance the force on both sides of the wheel, which can easily cause the other side of the wheel to break away from the track constraint. Especially in underground sections with many curves and slopes, the inertia of the mine car will exacerbate the risk of failure of the single-sided snap-fit. At best, it will cause the mine car to slip and hit the equipment, and at worst, it will cause the track to derail and cause casualties, which seriously restricts the safety and stability of mining transportation.

[0004] Therefore, it is necessary to invent a mine transport anti-runaway device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mine transport anti-runaway device to solve the problem mentioned in the background art. In the existing mine transport anti-runaway devices, the mainstream devices such as car stoppers and car barriers mostly adopt a single-sided snap-fit ​​limiting structure. They usually set a liftable wedge-shaped block or rotating baffle on one side of the track to achieve limiting by pressing against the side of the mine car wheel. However, this design has obvious defects. When the center of gravity of the mine car loaded with material shifts, the track has a lateral slope, or it is subjected to heavy load impact, the single-sided constraint is difficult to balance the force on both sides of the wheel, which can easily cause the other side of the wheel to break away from the track constraint. Especially in underground sections with many curves and slopes, the inertia of the mine car will exacerbate the risk of failure of the single-sided snap-fit. At best, it will cause the mine car to slip and hit the equipment; at worst, it will cause the track to derail and cause casualties, seriously restricting the safety and stability of mine transport.

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.

[0028] Please see the appendix Figure 1 - Appendix Figure 5 A mine transportation anti-runaway device includes a side fixing plate 1. Two side fixing plates 1 are symmetrically arranged. A first limiting block 2 and a second limiting block 3 are arranged on one side between the two side fixing plates 1. The first limiting block 2 and the second limiting block 3 are symmetrically arranged on both sides of the side fixing plate 1. The first limiting block 2 is fixedly connected between the two side fixing plates 1.

[0029] The bottom two sides of the second limiting block 3 are fixedly connected to sliders 31, and the top of the slider 31 is provided with a positioning block 32. The positioning block 32 is fixedly connected to the side of the second limiting block 3, and the inner side of the positioning block 32 is provided with a second insertion hole 321.

[0030] A sliding groove 12 is provided on the side of the side fixing plate 1 near the second limiting block 3. A protrusion 11 is provided at the top of the sliding groove 12. A plurality of first insertion holes 13 are evenly provided on the inner side of the protrusion 11.

[0031] Specifically, a first limiting block 2 is fixedly installed on one side between the two side fixing plates 1, and a second limiting block 3 is installed on the side corresponding to the first limiting block 2. The second limiting block 3 can slide between the two side fixing plates 1, thereby effectively setting the first limiting block 2 and the second limiting block 3 on both sides of the track wheel, thus effectively preventing the wheel from slipping. The second limiting block 3 can be adjusted according to the position of the wheel. At the same time, pins are provided on both sides of the second limiting block 3, which can be inserted into the inner side of the second insertion hole 321 and the first insertion hole 13 to limit the second limiting block 3, thereby effectively improving the limiting effect on the wheel.

[0032] Please see the appendix Figure 1 , Figure 2 and Figure 4 The slider 31 is correspondingly set to the slide groove 12, and the slider 31 is slidably connected to the inner side of the slide groove 12. The positioning block 32 is slidably set to the top of the protrusion 11, and the second insertion hole 321 is correspondingly set to the first insertion hole 13.

[0033] Specifically, by setting slider 31 and positioning block 32, slider 31 can be limited to slide inside the groove 12, and positioning block 32 can slide on the top of protrusion 11. The second insertion hole 321 is correspondingly set with the first insertion hole 13. A pin can be inserted into the inside of the second insertion hole 321 and the first insertion hole 13, thereby effectively limiting the position of positioning block 32.

[0034] Please see the appendix Figure 1 and Figure 3 The top of the first limiting block 2 and the second limiting block 3 are both provided with limiting plates 23. A first rubber pad 231 is fixedly connected to one side of the limiting plate 23, and a connecting rod 24 is fixedly connected to the bottom of the limiting plate 23.

[0035] Specifically, by setting a limiting plate 23, the limiting plate 23 can move to the top of the first limiting block 2 and the second limiting block 3 respectively, and the limiting plate 23 can move to the side of the wheel, thereby effectively limiting the wheel.

[0036] Please see the appendix Figure 3 A crossbar 21 is fixedly connected to the inner side of both the first limiting block 2 and the second limiting block 3. A groove 211 is opened on the inner side of the crossbar 21. A connecting rod 24 is slidably connected to the inner side of the groove 211. A first adjusting bolt 22 is threadedly connected to the side of the crossbar 21. The first adjusting bolt 22 passes through the crossbar 21 and is rotatably set on the inner side of the groove 211. A groove corresponding to the first adjusting bolt 22 is opened on the inner side of the bottom end of the connecting rod 24. The first adjusting bolt 22 is rotatably set on the inner side of the connecting rod 24.

[0037] Specifically, by setting a first adjusting bolt 22, which is threadedly connected to the inner side of the crossbar 21, and a groove corresponding to the first adjusting bolt 22 is opened on the inner side of the bottom end of the connecting rod 24, the first adjusting bolt 22 is rotatably set on the inner side of the connecting rod 24, so that rotating the first adjusting bolt 22 and the crossbar 21 will cause threaded rotation, thereby driving the connecting rod 24 to move inside the groove 211. The end of the first adjusting bolt 22 is limited to the inner side of the connecting rod 24, so that it cannot be unscrewed from the inner side of the connecting rod 24, thereby driving the connecting rod 24 to move, thereby effectively driving the limiting plate 23 to move, so that the limiting plate 23 is close to the side of the wheel, effectively limiting the wheel.

[0038] Please see the appendix Figure 1 , Figure 2 and Figure 5 Both sides of the side fixing plate 1 are provided with threaded holes 14. The inner side of the threaded hole 14 is threaded with a second adjusting bolt 4. The end of the second adjusting bolt 4 is provided with a pressure plate 41. The side of the pressure plate 41 is fixedly connected with a second rubber pad 42. The inner side of the side fixing plate 1 is provided with a hidden groove 15. The pressure plate 41 is located inside the hidden groove 15.

[0039] Specifically, threaded holes 14 are provided on both sides of the side fixing plate 1. The inner side of the threaded holes 14 is threaded with a second adjusting bolt 4. A pressure plate 41 is provided at the end of the second adjusting bolt 4. A second rubber pad 42 is fixedly connected to the side of the pressure plate 41. A hidden groove 15 is provided on the inner side of the side fixing plate 1. The pressure plate 41 is located inside the hidden groove 15. By providing the hidden groove 15, it is easy to hide the pressure plate 41 and the second rubber pad 42. By providing the second adjusting bolt 4, the second adjusting bolt 4 is rotatably located inside the pressure plate 41 and is limited to the inner side of the pressure plate 41. The second adjusting bolt 4 cannot be unscrewed from the inner side of the pressure plate 41. In actual use, after the side fixing plates 1 on both sides are slidably set on both sides of the track, the pressure plate 41 can be moved by turning the second adjusting bolt 4, thereby effectively pressing the pressure plate 41 against the side of the track, thereby effectively fixing the side fixing plate 1 on both sides of the track. The two sets of pressure plates 41 are symmetrically arranged on the side fixing plates 1 on both sides, which effectively increases the fixing effect.

[0040] The working principle of this utility model is as follows: In specific use, the side fixing plate 1 is slid along both sides of the track, so that the bottom end of the first limiting block 2 is positioned above the track and moves. After the first limiting block 2 moves below the wheel, the second adjusting bolt 4 is turned to drive the pressure plate 41 to move, thereby effectively pressing the pressure plate 41 against the side of the track, thus effectively fixing the side fixing plate 1 to both sides of the track. The two sides of the side fixing plate 1 are symmetrically provided with two sets of pressure plates 41, which effectively increases the fixing effect.

[0041] The second limiting block 3 is slid from the other side of the side fixing plate 1 to between the two side fixing plates 1, so that the slider 31 slides to the inside of the slide groove 12, so that the second limiting block 3 moves closer to the other end of the wheel and is set at the bottom of the other end of the wheel. After the position is set, a pin is inserted into the inside of the second insertion hole 321 and the first insertion hole 13 to limit the position of the second limiting block 3.

[0042] By setting a first adjusting bolt 22, which is threadedly connected to the inner side of the crossbar 21, and a groove corresponding to the first adjusting bolt 22 is opened on the inner side of the bottom end of the connecting rod 24, the first adjusting bolt 22 is rotatably set on the inner side of the connecting rod 24, so that rotating the first adjusting bolt 22 and the crossbar 21 will cause threaded rotation, thereby driving the connecting rod 24 to move inside the groove 211. The end of the first adjusting bolt 22 is limited to the inner side of the connecting rod 24, so that it cannot be unscrewed from the inner side of the connecting rod 24. The movement of the connecting rod 24 will effectively drive the limiting plate 23 to move, so that the limiting plate 23 is close to the side of the wheel, effectively limiting the wheel.
