Description

TECHNICAL FIELD

[0001] The utility model relates to a car stopper technical field, concretely is a blocking device for mine car loading and unloading. BACKGROUND

[0002] The car stopper, also known as a parking device, is one of the important facilities of a coal mine transportation system, and belongs to a car running prevention device. It is generally installed at the top of a slope. On one hand, it limits the mine car to stay at a specified position for loading and unloading minerals. On the other hand, it is used to prevent car running accidents. It is often used in cooperation with a car pushing machine, a car tipping machine, a car climbing device, a cage, and a dispatch winch, etc. Currently, the car stopper for stopping the mine car cannot adjust the distance between the blocking blocks, which is not convenient for being applied to mine car tracks with different distances, and cannot meet the needs of use.

[0003] For example, the Chinese utility model patent CN219237044U proposes a blocking device for mine car loading and unloading, which comprises a base fixed horizontally on the ground and perpendicular to the mine car track. The base has a cavity inside and an upper surface with two limiting openings communicating with the cavity. The two openings are arranged along the width direction of the base. Two oppositely arranged car stopping assemblies are arranged above the limiting openings. A distance adjusting assembly is arranged in the cavity and drives the two car stopping assemblies to move towards or away from each other to adjust the distance between them.

[0004] However, in actual use, it is troublesome to adjust the width of the car stopping assembly. It needs to be adjusted slowly to the specified position for fixation by rotating the worm on both sides. Currently, the commonly used width of the mine track is only three kinds. This adjustment method is time-consuming and tedious. Therefore, we propose a blocking device for mine car loading and unloading, which can quickly adjust the width of the car stopping assembly.
