Description

Technical Field

[0001] This utility model relates to the field of coal pillar recovery traction technology, and in particular to a rolling sliding traction device applied to coal pillar recovery operations in main roadways. Background Technology

[0002] In the field of coal mining, the main roadway pillar is a key structure that ensures the stability of underground roadways. After the main coal seam is mined, it needs to be recycled to achieve secondary utilization of resources. At the same time, it creates conditions for subsequent roadway maintenance and connection with the mining area. The main roadway pillar recycling operation is characterized by narrow space, complex geological conditions, and large operating loads. It places extremely high demands on the flexibility, load-bearing capacity, and safety of the traction equipment. The traction device needs to control the material transfer direction after the coal pillar is broken, while adapting to the uneven ground and limited working space in the roadway, so as to avoid safety accidents caused by equipment jamming or overturning.

[0003] The traction devices currently used in coal pillar recovery operations in main roadways cannot dynamically adjust the height of the wheels according to the terrain. Due to the unevenness of the roadway surface caused by mining, the wheels with a fixed height are prone to jamming during travel. At present, the main solution is to manually lay auxiliary materials, such as steel plates and gravel, on the raised or sunken parts of the roadway surface to create passage conditions for the traction device by leveling the local road surface. In some scenarios, small leveling equipment is used to pre-process the work path in advance. However, there are still shortcomings. Manually laying auxiliary materials requires a lot of manpower and time, especially in long-distance work paths, where the laying efficiency is extremely low, which seriously slows down the overall progress of coal pillar recovery. Moreover, steel plates, gravel and other materials are difficult to transport in the roadway, and the unevenness of the laying may even aggravate the wheel bumps. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rolling sliding traction device for coal pillar recovery operations in main roadways, aiming to solve the problem that the traction devices used in existing coal pillar recovery operations in main roadways cannot dynamically adjust the height of the wheels according to the terrain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rolling sliding traction device for coal pillar recovery operations in main roadways, comprising a vehicle body, motor slots fixedly connected to the top left and right sides of the vehicle body, a motor I fixedly connected to the inner wall of the motor slot on the left side, a rotating shaft I fixedly connected to the output end of the motor I, a bevel gear I fixedly connected to the outer wall of the rotating shaft I, a bevel gear II meshing with the outer wall of the bevel gear I, a rotating shaft II fixedly connected to the bottom of the bevel gear II, a fixed shell rotatably connected to the outer wall of the rotating shaft II, a threaded rod II fixedly connected to the bottom of the rotating shaft II, a connecting rod threadedly connected to the outer wall of the threaded rod II, and a traction mechanism provided on the left side of the vehicle body, the traction mechanism being used for traction fixation.

A rotating shaft 2 is rotatably connected to the middle of the connecting block 2. A short rod is rotatably connected to the middle of the rotating shaft 2.

[0007] As a further description of the above technical solution: The top of the short rod is fixedly connected to a threaded rod, and a nut is threaded onto the outer wall of the threaded rod.

[0008] As a further description of the above technical solution: The front side of the connecting rod is rotatably connected to a rotating shaft three, and a wheel is rotatably connected to the outer wall of the rotating shaft three.

[0009] As a further description of the above technical solution: A limiting block is fixedly connected to the front side of the rotating shaft three, and a connecting plate one is fixedly connected to the right side of the fixed shell.

[0010] As a further description of the above technical solution: A second connecting plate is fixedly connected to the right side of the first connecting plate, and the rear side of the second connecting plate is fixedly connected to the front side of the vehicle body.

[0011] As a further description of the above technical solution: The outer wall of the connecting block is fixedly connected to an L-plate, and the outer wall of the L-plate is threaded with multiple bolts.

[0012] As a further description of the above technical solution: The bottom of the nut is engaged with the outer wall of the connecting block three, and a hook is fixedly connected to the bottom of the C-shaped plate one.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the bevel gear set and the threaded rod to drive the connecting rod and the wheel to move up and down, so that the tractor can flexibly adjust the wheel height according to different terrains and environments, effectively avoiding the problem of wheel suspension or jamming caused by terrain undulations, obstacles, etc., ensuring stable driving in complex underground environments or diverse terrains, and improving the adaptability of the operation scenarios.

This can effectively prevent the mechanism from loosening or falling off due to vibration or external force during traction, ensuring the safety and stability of traction operation and reducing the risk of failure.

[0022] Working principle: When facing different terrains and environments, starting motor 4 causes the output end of motor 4 to drive rotating shaft 5 to rotate. The rotation of rotating shaft 5 causes bevel gear 6 to rotate. The rotation of bevel gear 6 then drives bevel gear 7 to rotate. The rotation of bevel gear 7 drives rotating shaft 8 to rotate, which in turn drives threaded rod 9 to rotate. This allows connecting rod 11 to move up and down with the rotation of threaded rod 9, which in turn drives wheel 13 to move up and down. Ultimately, this allows the tractor to adjust the height of wheel 13 according to different underground environments. After C-shaped plate 203 and C-shaped plate 205 are secured to connecting rod 202, short rod 208 is rotated so that it can rotate around pivot 207. When short rod 208 and threaded rod 209 are engaged with connecting block 210, nut 211 on threaded rod 209 is tightened to fix C-shaped plate 205 and C-shaped plate 203, thus fixing the traction mechanism 2.
