Description

Technical Field

[0001] The utility model relates to a coal mine transportation technology, in particular to a coal mine transportation device which is easy to adjust. Background Art

[0002] During the ore transportation process, mine cars are usually used for loading and transportation. When transporting, the mine cars travel along a fixed track route to transport the ore to the designated location.

[0003] Most of the existing mine cars have wheels with fixed wheel gauges. During transportation, since the transportation routes have to pass through different sites, the tracks for the mine cars to travel must be designed and installed according to the actual site conditions and design requirements. Therefore, during the mine car transportation process, it is necessary to travel on tracks with different track gauges. For example, the track gauge in the inclined shaft is required to be 1400mm, while the track gauge in the middle level tunnel is 600mm. When the track gauge changes during the mine car transportation process, the mine car type needs to be replaced and the ore needs to be transferred from the original transport mine car to another transport mine car before it can continue to be transported. There are problems such as long-term occupation of the transportation channel and high labor consumption. A small number of mine cars with variable wheel gauges need to set up multiple sets of wheels according to the adjusted wheel gauge. The wheel frame needs to be replaced when adjustment is needed, and the adjustment operation is not convenient. Therefore, we propose a coal mine transportation device that is easy to adjust to solve the above problems. Utility Model Content

One side of the moving plate 7 is fixedly connected to It is connected to a guide plate 9, on which meshing teeth 10 are evenly spaced. The guide plate 9 is arranged on the inner side of the adjacent through groove 5. A rotating shaft 11 is rotatably connected between the two horizontal plates 4. A gear 12 is fixedly connected to the outer side of the rotating shaft 11. The gear 12 meshes with the adjacent meshing teeth 10. The front and rear sides of the outer side of the rotating shaft 11 are respectively fixedly connected with bumps 13. A ring sleeve 14 is fixedly connected to the top of the upper horizontal plate 4 of the two horizontal plates 4. A rotating frame 15 is slidably connected in the ring sleeve 14. The rotating frame 15 is arranged on the outer side of the rotating shaft 11, and a spring 16 is provided between the rotating frame 15 and the rotating shaft 11.

[0020] The gear 12 is engaged with the gear 12 and the movable plate 7 is driven by the gear 12 to move. The rotating shaft 11 is used to control the rotation of the gear 12. The protrusion 13 is used to guide the rotating frame 15 so that it can only slide on the rotating shaft 11 and cannot rotate relative to it. The sleeve 14 is used to limit the rotation of the rotating frame 15 so that it cannot rotate when it contacts the sleeve 14. The spring 16 is used to pull the rotating frame 15 to maintain contact with the sleeve 14 when not subject to external force. Through the set distance adjustment component, the wheelbase of the transport device can be adjusted according to the required length. The adjustment range is relatively wide and the adjustment operation is simpler. It can be achieved by simply rotating the rotating frame 15. After the adjustment is completed, the locking operation of the rotating frame 15 is also relatively simple, which simplifies the adjustment steps and facilitates the adjustment operation.

[0021] The top of the rotating shaft 11 is fixedly connected to a top plate 17, and a spring 16 is located below the top plate 17. One end of the spring 16 abuts against the bottom of the top plate 17. The top plate 17 is used to limit the rotating shaft 11 in the rotating frame 15 to prevent it from escaping from the rotating frame 15. The spring 16 can push the rotating frame 15 downward under the action of the top plate 17 to maintain contact with the ring sleeve 14, thereby conveniently ensuring that the rotating frame 15 is always locked by the ring sleeve 14 when not in operation, thereby improving the stability of the device.

[0022] The outer side of the rotating frame 15 and the inner wall of the ring sleeve 14 are all provided with teeth and grooves. The rotating frame 15 is inserted into the inner side of the ring sleeve 14. The provided teeth and grooves can facilitate the rotating frame 15 to be inserted into the inner side of the ring sleeve 14. It is restricted by the ring sleeve 14 and is convenient to lock the rotating frame 15.

[0023] A stepped groove is provided at the bottom of the rotating frame 15. The upper cross-section of the stepped groove is adapted to the size of the top plate 17, and the lower cross-section of the stepped groove is adapted to the outer contour size of the rotating shaft 11. The stepped groove allows the top plate 17 to move within it but cannot be separated. Before installation, the rotating frame 15 is composed of two halves, which are placed on the outside of the rotating shaft 11 and the spring 16, and then the two halves are merged into a whole rotating frame 15 for easy installation.

[0024] The present invention is specifically implemented as follows: when it is necessary to adjust the wheelbase, the mine car is first lifted up as a whole to make the moving wheel 8 leave the ground, and then the rotating frame 15 is pulled upward to separate it from the ring sleeve 14, and at the same time the spring 16 is deformed to store elastic force, and then the rotating frame 15 is rotated so that it drives the rotating shaft 11 and the gear 12 to rotate through contact with the protrusion 13, and the gear 12 engages with the meshing teeth 10 on both sides to drive the guide plate 9 to move, and the moving wheels 8 on both sides are pulled by the moving plate 7 to move relative to each other until the appropriate spacing is adjusted, and then the rotating frame 15 is released to reset under the elastic force of the spring 16 and reinserted into the ring sleeve 14.
