Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation technology, specifically a coal mine transport vehicle. Background Technology

[0002] Coal mine transport vehicles are specially designed for transporting coal and other materials inside and outside mines. The design of these vehicles takes into account safety, efficiency, and the ability to adapt to complex working conditions, which is crucial for ensuring the safety and efficiency of mining operations. Among coal mine transport vehicles, tipper cars are widely used. The cross-section of the car body is V-shaped or U-shaped and supported on the tipping rails of the frame. The car body is unloaded by tipping on the tipping rails, and the mine car moves along the rails. The common rail is 30kg / m and the track gauge is 600. This type of rail is a light rail and is suitable for low-volume and low-speed scenarios. The track gauge of 600 has the advantage of narrow rails, high flexibility, and is suitable for underground or space-constrained coal mine environments.

[0003] In the actual transportation of coal mines, the front end of the current coal mine transport vehicle often experiences collisions. Due to the lack of effective buffer protection, the end of the coal mine vehicle is prone to deformation after being hit by a collision. At the same time, the coal transported inside is also prone to spillage due to excessive collision force, which affects the actual transportation effect. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a coal mine transport vehicle, which has the following beneficial effects:

[0017] 1. A buffer protection assembly is constructed using a damping cylinder, a return spring, a compression column, a driving wedge, a buffer spring, a squeezing wedge, and a collision arc block. When the collision arc block is impacted, it drives the squeezing wedge to move, and the buffer spring provides initial buffering. When the impact stress is high, the squeezing wedge compresses the squeezing wedges on both sides, causing them to move in opposite directions. This allows the compression column to move into the damping cylinder, where it compresses the return spring, achieving the second step of buffer protection. Simultaneously, the damping cylinder contains damping fluid, which is compressed during the movement of the compression column, achieving the third step of buffer energy absorption. Through multiple sets of buffer protection measures, the transport vehicle is buffered and protected, preventing collision damage and ensuring smooth transportation of coal to the mine.

[0018] 2. Side magnetic strips, end magnetic strips, and top magnetic strips are fixed and limited by magnetic adsorption on the sides of the columns and crossbeams, making the installation and removal of the side magnetic strips simple and convenient. The multiple magnetic strips facilitate the installation of shielding cloth at different positions on the sides of the columns and crossbeams, and the shielding cloth protects the outside of the tilting track and track wheels, preventing coal from accumulating on the tilting track, preventing coal from clogging the slots, affecting the fit between the protruding column and the slot, preventing the track wheels from failing to tilt, and avoiding any impact on the actual deflection and unloading of the car.

[0019] 3. The system utilizes an installation groove, sliding block, magnetic adsorption block, guide groove, snap-fit ​​groove, limit block, and pull rod. The sliding block's movement allows the limit block at the side of the carriage to snap into its internal snap-fit ​​groove, maintaining the carriage's stable position for loading and transportation, preventing loosening. The pull rod drives the sliding block along the installation groove, and the sliding block drives the magnetic adsorption block along the guide groove, causing the magnetic adsorption block to adhere to the top of the guide groove. This facilitates separation of the limit block from the sliding block, enabling the carriage to deflect and unload materials, maintaining stability during loading and transportation, and improving operational convenience.

[0031] A mounting box 10 is installed at the bottom of the forward end of the frame 1, and a buffer box 11 is connected to one side of the mounting box 10. Two damping cylinders 12 are symmetrically installed on both sides inside the mounting box 10. A return spring 13 is embedded in the inner side of the damping cylinder 12.

A collision arc block 18 is fixedly connected to the end of the compression wedge 17. A rubber baffle 19 is provided at the edge of the buffer box 11. The damping cylinder 12 is filled with a viscous damping fluid. The compression column 14 slides along the inner wall of the damping cylinder 12. The rubber baffle 19 is made of flexible rubber and can compress the damping fluid during the movement of the compression column 14 to achieve buffering and energy absorption, and also allows the rubber baffle 19 to deform under force.

[0032] The top edges of both sides of the column 4 are magnetically connected to side magnetic strips 20, and the top edges of the front and rear sides of the column 4 are magnetically connected to end magnetic strips 21. The top side of the crossbeam 5 is magnetically connected to a top magnetic strip 22. The edges of the side magnetic strips 20, end magnetic strips 21 and top magnetic strips 22 are all connected to shielding cloth 23. The shielding cloth 23 on the edges of the side magnetic strips 20, end magnetic strips 21 and top magnetic strips 22 shields the outside of the flipping track 6 and the track wheel 7. The shielding cloth 23 facilitates the shielding and protection of the outside of the flipping track 6 and the track wheel 7, preventing coal from accumulating on the flipping track 6 and preventing coal from clogging the groove 9, affecting the fit between the protruding column 8 and the groove 9, and further preventing the track wheel 7 from failing to flip.

[0033] A mounting groove 24 is provided in the middle of the crossbeam 5. A sliding block 25 is embedded and slidably connected in the mounting groove 24. Adsorption magnetic blocks 26 are fixedly connected to both sides of the sliding block 25. A guide groove 27 is provided on the side of the mounting groove 24 corresponding to the adsorption magnetic blocks 26. A snap-fit ​​groove 28 is provided inside one side of the sliding block 25. A limit block 29 is connected to the side of the carriage 3 corresponding to the snap-fit ​​groove 28. The sliding block 25 slides along the inside of the mounting groove 24, and the adsorption magnetic blocks 26 slide along the inside of the guide groove 27. The limit block 29 and the snap-fit ​​groove 28 are engaged and connected. By sliding the sliding block 25, the limit block 29 on the side of the carriage 3 can be snapped into the snap-fit ​​groove 28 inside it, so that the carriage 3 keeps its position stable. A pull rod 30 is connected to the top of the sliding block 25.

[0034] The working principle and usage process of this utility model are as follows: First, the frame 1 moves along the rail with a gauge of 600 mm and a steel rail of 30 kg / m via the wheels 2. The carriage 3 is placed inside the frame 1. When the carriage 3 is loaded, the sliding block 25 is used to make the limiting block 29 on the side of the carriage 3 engage with the locking groove 28 inside it, so that the carriage 3 is kept in a stable position, which facilitates loading and transportation and prevents the carriage 3 from becoming loose.

[0035] When the carriage 3 needs to be tilted for unloading, the pull rod 30 drives the sliding block 25 to slide along the mounting groove 24, and the sliding block 25 drives the magnetic adsorption block 26 to slide along the guide groove 27, so that the magnetic adsorption block 26 is adsorbed to the top of the guide groove 27, thereby facilitating the separation of the limiting block 29 from the sliding block 25, thus facilitating the tilting and unloading of the carriage 3. This ensures that the carriage 3 can not only guarantee the stability during the loading and transportation process, but also facilitate the tilting and unloading.

[0036] During the loading and unloading process of the carriage 3, the side magnetic strips 20, end magnetic strips 21 and top magnetic strips 22 are fixed by magnetic adsorption at the edges of the columns 4 and crossbeams 5. Combined with the shielding cloth 23 connected to the side magnetic strips 20, end magnetic strips 21 and top magnetic strips 22, it is convenient to set the shielding cloth 23 at different positions on the sides of the columns 4 and crossbeams 5. The shielding cloth 23 can conveniently shield and protect the outside of the tilting track 6 and the track wheel 7, prevent coal from accumulating on the tilting track 6, prevent coal from blocking the groove 9, affecting the fit between the protruding column 8 and the groove 9, prevent the track wheel 7 from failing to tilt, and avoid affecting the actual deflection and unloading of the carriage 3.

[0037] During the process of the frame 1 driving the carriage 3 to move along the track, when the collision arc block 18 at the forward end of the frame 1 is hit, the collision arc block 18 drives the squeezing inclined block 17 to move into the buffer box 11. At this time, the buffer spring 16 achieves the initial buffering of the impact pressure on the collision arc block 18.

[0038] When the impact stress is large, the compression wedge 17 is used to compress the two compression wedges 17 on both sides, causing the two compression wedges 17 to move in opposite directions. This allows the compression column 14 to move into the damping cylinder 12, and the compression column 14 compresses the return spring 13 to achieve the second step of buffer protection. At the same time, the damping cylinder 12 contains damping fluid, which is compressed synchronously during the movement of the compression column 14, thus achieving the third step of buffer energy absorption. In this way, multiple sets of buffer protection methods are used to buffer and protect the transport vehicle, avoid collision damage, and enable the coal mine car to transport coal smoothly.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
