Description

Technical Field

[0001] The utility model relates to a mine car roof with multiple protections, belonging to the technical field of mine car roofs. Background Art

[0002] For example, a high-strength mine car cab roof disclosed in the application number: CN217022435U solves the problem that the mine car cab roofs on the current market are all composed of simple steel plate structures and cannot protect the driver when a falling rock hits the roof. It includes two vehicle frames and a base. Second limiting tubes are fixedly installed at the four corners of the base, and first limiting tubes are welded on the tops of the four second limiting tubes. A top plate is fixedly installed between the tops of the two vehicle frames, and a storage groove is opened on the top of the top plate. A shock-absorbing plate is arranged inside the storage groove. When a falling rock hits the roof, it will contact the shock-absorbing plate on the top plate, and then several springs at the bottom of the shock-absorbing plate can play a buffering role on the shock-absorbing plate, thereby reducing the impact force brought by the falling rock to the top plate, and further achieving the purpose of protecting the driver.

[0003] Based on retrieval and analysis, it is found that the existing technology still has deficiencies:

[0004] The front side of the car roof in the existing technology is a detachable structure, and there is a spring structure between the roof and the car shed. During use, the spring is squeezed for a long time, which easily causes it to deform, and the roof frame is relatively heavy and the cost is relatively high. Therefore, a mine car roof with multiple protections is needed to improve the above deficiencies. Content of the Utility Model
