Before using the unloading platform 1 for unloading, the screw cap 39 on the connecting pipe 38 can be screwed onto the outer surface of one end of the guide pipe 36, and then lubricating oil can be added to the inside of the lubricating oil tank 37, so that the lubricating oil can enter the guide cavity 31 and the guide hole 32 through the connecting pipe 38 and the guide pipe 36 under the action of gravity. At this time, the round rod 35 will block the outlet of the guide hole 32. When the mine car enters the unloading platform 1 for unloading, the edge of the mine car will be engaged with the supporting wheel on the unloading platform 1 and continue to move, and the unloading wheels on both sides of the bottom of the mine car will be stuck in the inside of the curved track body 2. When the unloading wheel moves to a certain position inside the curved track body 2, the surface of the unloading wheel will abut against the round rod 35, pushing it upward, driving the spring 34 The guide hole 32 is opened to allow the lubricating oil inside to flow out and be smeared on the outer surface of the unloading wheel for lubrication.

[0033] Reference Figure 6 As shown, this embodiment discloses a stopper device 4 comprising two bolts 44. A screw block 41 is symmetrically fixedly connected to one side of the lubricating oil tank 37. A groove block 42 is symmetrically fixedly connected to both sides of the inner wall of the unloading platform 1. The screw block 41 is inserted into the inner wall of the groove block 42. A threaded hole 43 is formed on one side of the inner wall of the groove block 42. One end of the bolt 44 is screwed into the threaded hole 43 and the inner wall of the screw block 41. When the lubricating oil tank 37 is installed on one side of the curved rail body 2 for lubrication, the two screw blocks 41 on one side of the lubricating oil tank 37 can be inserted into the inner wall of the groove block 42 respectively. Then, the bolt 44 is screwed into the threaded hole 43 and the inner wall of the screw block 41. When the screw block 41 is retained in the inner wall of the groove block 42, the lubricating oil tank 37 can be fixed in place in the inner wall of the unloading platform 1, so that it can be secondary fixed during the lubrication operation of the curved rail body 2, preventing it from shaking.

[0035] Working principle: before using the unloading platform 1 to unload, the screw cap 39 on the connecting pipe 38 can be screwed onto the outer surface of one end of the guide pipe 36, and then lubricating oil can be added to the inside of the lubricating oil tank 37, so that the lubricating oil can enter the guide cavity 31 and the guide hole 32 through the connecting pipe 38 and the guide pipe 36 under the action of gravity. At this time, the round rod 35 will block the outlet of the guide hole 32. When the mine car enters the unloading platform 1 for unloading, the edge of the mine car will be engaged with the supporting wheel on the unloading platform 1 and continue to move, and the unloading wheels on both sides of the bottom of the mine car will be stuck in the curved track body 2. When the unloading wheel moves to a certain position inside the curved track body 2, the surface of the unloading wheel will abut the round rod 35, pushing it upward, driving the spring The spring 34 contracts and then opens the guide hole 32, allowing the lubricating oil inside to flow out and be smeared on the outer surface of the unloading wheel for lubrication. When the unloading wheel leaves the round rod 35, under the reset action of the spring 34, the round rod 35 will block the guide hole 32 again to prevent the lubricating oil from flowing out all the time. The lubrication of the lubricating oil can reduce the contact friction between the curved rail body 2 and the unloading wheel, making it easier to guide it and reduce noise. At the same time, it can avoid the occurrence of jamming during guidance that affects the operation of the mine car, thereby improving the unloading efficiency and unloading effect. Finally, under the guidance of the curved rail body 2, the mine car can open the bottom of the mine car according to the prescribed trajectory for unloading operations, and close the bottom of the mine car according to the trajectory after unloading is completed.

When the screw hole blocks 41 are limited in the inner wall of the groove block 42, the lubricating oil tank 37 can be fixed in the inner wall of the unloading platform 1, so that it can be secondary limited and fixed when the curved rail body 2 is lubricated, so that it is not easy to shake.
