Description

Technical Field

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

[0002] During the coal mining process, the mined coal needs to be transported from the mining site to a designated location, which requires coal mining transportation equipment.

[0003] Currently, existing coal mine transport equipment often has some problems during material unloading operations. For example, the hoppers of some transport devices are prone to slipping during the tipping process, leading to unstable unloading and affecting operations.

[0004] Therefore, those skilled in the art have provided a coal mine transportation device to solve the problems mentioned above. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a coal mine transportation device.

[0008] Frame;

[0009] Two arc-shaped grooves are symmetrically arranged at both ends of the top of the vehicle frame;

[0010] Two limiting grooves are symmetrically arranged on the arc-shaped groove. The vertical cross-section of the limiting groove is set as an isosceles trapezoid with a larger upper section and a smaller lower section. The vertical cross-section of the limiting groove increases uniformly from the center of the arc-shaped groove to both sides.

[0011] A U-shaped bucket is installed inside the vehicle frame;

[0012] Two arc-shaped plates are provided and symmetrically fixedly installed on both sides of the U-shaped bucket. When the U-shaped bucket is in a vertical state, the bottom of the arc-shaped plate contacts the center of the bottom of the arc-shaped groove.

[0013] Two inclined blocks are provided, located on the lower surface of the arc-shaped plate. Both ends of the inclined blocks are set as isosceles trapezoids, and the cross-section of the inclined blocks increases uniformly from bottom to top.

[0014] When the U-shaped bucket is pulled to one side, the inclined block moves upward along the limiting groove and goes deeper into the limiting groove.

[0015] Preferably, two limiting blocks are symmetrically fixedly installed at both ends of the top of the frame, and the limiting blocks are set in an "L" shape.

[0016] Preferably, the frame is arranged in a "U" shape, and the width of the U-shaped bucket is equal to the width between the two vertical parts of the frame.

[0026] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, those of ordinary skill in the art can propose various structural ways and implementation ways that can be mutually replaced. Therefore, the following detailed embodiments and the accompanying drawings are only illustrative descriptions of the technical solution of the utility model and should not be regarded as the whole of the utility model or as a limitation or restriction on the technical solution of the utility model.

[0027] A coal mine transportation device, referring to FIGS. 1-3, includes:

[0028] The frame 1 can run along the track, providing a basis for the movement of the entire device.

[0029] The U-shaped bucket 2 is installed inside the frame 1 and is used to load materials such as coal. The frame 1 is set in the shape of a "U" and the width of the U-shaped bucket 2 is equal to the width between the two vertical parts of the frame 1. This ensures the stability of the U-shaped bucket 2 and allows it to be firmly fixed inside the frame 1, effectively preventing lateral swaying caused by bumps during transportation.

[0030] There are two arc-shaped grooves 11, symmetrically arranged at both ends of the top of the frame 1.

[0031] Two limiting grooves 12 are symmetrically arranged on the arc-shaped groove 11. The vertical cross-section of the limiting groove 12 is set as an isosceles trapezoid with a larger top and a smaller bottom. The vertical cross-section of the limiting groove 12 increases uniformly from the center of the arc-shaped groove 11 to both sides. This structural design plays a limiting and guiding role in the U-shaped bucket 2 during the flipping process. The gradually changing cross-section design can perfectly adapt to the position changes of different angles when the U-shaped bucket 2 flips, making the flipping action more regular, preventing jamming or deviation, and laying a solid foundation for smooth material pouring.

[0032] Two arc-shaped plates 21 are provided and symmetrically fixed on both sides of the U-shaped bucket 2. When the U-shaped bucket 2 is in a vertical state, the bottom of the arc-shaped plate 21 contacts the center of the bottom of the arc-shaped groove 11. It can automatically return to the upright position after the U-shaped bucket 2 tilts without additional reset operation, which simplifies the operation process, saves manpower and time, and can effectively improve work efficiency in continuous operation scenarios.

[0033] Two inclined blocks 22 are provided and located on the lower surface of the arc plate 21. Both ends of the inclined blocks 22 are set as isosceles trapezoids, and the cross section of the inclined blocks 22 increases uniformly from bottom to top. They can be used to support the U-shaped bucket 2 so that the U-shaped bucket 2 can quickly maintain stability.

[0034] Furthermore, the four inclined blocks 22 are respectively inserted into the bottom of the four limiting grooves 12, and the bottom of the inclined blocks 22 contacts the two sides of the limiting grooves 12, which enables the inclined blocks 22 to be positioned and allows the inclined blocks 22 to move smoothly within the limiting grooves 12, reducing frictional resistance and ensuring the smoothness of the U-shaped bucket 2's overturning process.

[0035] When the U-shaped bucket 2 is pulled to one side, the inclined block 22 moves up along the limiting groove 12 and goes deep into the limiting groove 12. During the pulling process, due to the design of the inclined block 22 and the limiting groove 12 being larger at the top and smaller at the bottom, the U-shaped bucket 2 will not easily slide down when it is pulled to one side and tilted, which improves the stability of tilting and pouring. The angle requirement for pulling is low, and the operator does not need to precisely control the direction, which greatly simplifies the operation process.

[0036] When the inclined block 22 abuts against the inner wall of the top of the limiting groove 12, the U-shaped bucket 2 rotates around the contact surface between the inclined block 22 and the limiting groove 12, which provides a support point for continued rotation and can empty the coal completely. This rotation method allows the tilt angle of the U-shaped bucket 2 to reach its maximum, ensuring that the material slides completely under the action of gravity, avoiding residue, improving the thoroughness of material unloading, and reducing subsequent cleaning work.

[0037] Two limiting blocks are symmetrically fixed at both ends of the top of the frame 1, and the limiting blocks are set in an "L" shape. When the U-shaped bucket 2 is flipped to the maximum angle or an unexpected shaking occurs, the limiting blocks can effectively block it from the side, which can prevent the U-shaped bucket 2 from falling off the frame 1 in case of an accident, thus improving the safety of the device.

[0038] The top of both sides of the U-shaped bucket 2 is provided with strip grooves 23, and the two strip grooves 23 are symmetrically arranged, which makes it convenient to pull through the area where the strip grooves 23 are located. When it is necessary to flip the U-shaped bucket 2 to one side, the other strip groove 23 of the U-shaped bucket 2 can be pulled by the traction rope on the same side, which is convenient and further reduces the difficulty of operation.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
