Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roadway transportation, in particular to a mine car protection device in an inclined roadway. BACKGROUND

[0002] The mine car is the core equipment for mining and transportation in mines, and is mainly applied to complex scenes such as underground mines, open-pit mines and ore transfer yards. Its working environment is highly challenging: it needs to run on narrow space and undulating track or unpaved road, withstand the impact of concave-convex road, flying of loose materials and accumulation of water and dust; at the same time, it needs to bear high-density and large-tonnage transportation tasks, frequently experience dynamic loads such as starting, braking and sharp turning, and is exposed to high humidity, strong dust, temperature fluctuations and electromagnetic interference for a long time. The above environment puts high requirements on the structural strength, running stability and axle distance system accuracy of the mine car, and needs to maintain stable geometric parameters under complex stress to ensure safety.

[0003] Although the mine car improves the axle distance stability through frame reinforcement and bogie optimization, the axle distance deviation still frequently occurs in actual operation. The main reasons include: dynamic load impact, long-term stress accumulation and maintenance lag. Its harm is significant: it destroys the running stability, causes a sharp increase in lateral force, causes derailment risk; aggravates the wear of wheel flange and track; increases energy consumption and material leakage; and even causes derivative accidents such as cargo collapse, threatening personnel safety and production continuity.

[0004] In the prior art, after the axle distance deviates, it is mostly checked and repaired after one trip of the mine car, and the axle inclination is more likely to occur in the axle distance deviation in some special terrain. Under the combined influence of the axle inclination and the axle distance deviation, the mine car is more likely to roll over, threatening the health of the workers and affecting the production of the coal mine. SUMMARY

[0005] Therefore, the technical problem to be solved by the present application is to provide a mine car protection device in an inclined roadway to solve the problems in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a mine car protection device in an inclined roadway, comprising a mine car body, a guide rail used in cooperation with the mine car body, and an axle provided on the mine car body for connecting the wheels, further comprising:

[0014] As preferred, a sliding block is fixedly installed on the shell, and the sliding block is slidingly installed in the limiting groove on the fixing block.

[0015] As preferred, an installation hole is formed in the side wall of the second installation cavity, and the installation hole is consistent with the axle in shape and size.

[0016] As preferred, an arc segment is arranged on the special-shaped piece, and a brake block is arranged on the arc segment.

[0017] As preferred, when the axle is in a horizontal state, the jacking rod still keeps an inclined state and abuts against the bottom plate of the mine car body when the control assembly moves.

[0019] Compared with the prior art, the present application provides a mine car protection device in an inclined tunnel, which has the following beneficial effects:

[0020] 1. The present application sets up a control assembly and a locking part, when the axle offset occurs, the auxiliary wheel can provide additional support force to the mine car from the side, so that the operation of the mine car is more stable, and when the axle offset is too large, the axle may be separated from the track and cause derailment, the auxiliary wheel and the locking part cooperate to set a maximum distance, when the control assembly moves to the maximum distance, it is locked to prevent the distance of the axle offset from continuing to expand.

[0044] In one embodiment: the brake 36 comprises a top rod 361, one end of the top rod 361 is fixedly installed with a special-shaped piece 362, one end of the special-shaped piece 362 away from the top rod 361 is fixedly installed with a mounting block 363, the mounting block 363 is fixedly installed with a rotating shaft 364, the rotating shaft 364 is rotatably connected with the inner wall of the second installation cavity 34, the rotating shaft 364 is sleeved with a torsion spring 38, one end of the torsion spring 38 is fixedly connected with the inner wall of the second installation cavity 34, and the other end is fixedly connected with the mounting block 363.

[0045] The working principle and beneficial effects of the above technical solution are that the initial state of the top rod 361 abuts against the mine car body 1, when the axle 7 is inclined, the top rod 361 will be extruded by the mine car body 1 when the brake 36 moves on the axle 7, and will rotate to brake the axle 7.
