Description

Technical Field

[0001] The utility model relates to the technical field of mine cars, in particular to an automatic unhooking device for inclined shaft mine cars. Background Art

[0002] Mine cars are railway vehicles that transport materials such as coal and waste rock. They are special vehicles for mine rail transportation. In order to adapt to the narrow conditions of underground tunnels, they have compact dimensions and include trucks, manpower cars and material cars. Mine cars are narrow-gauge railway transport vehicles that transport bulk materials such as coal, ore and waste rock in mines. They are generally towed by locomotives or winches. Mine cars are generally connected with pins and chains to facilitate the transportation of materials such as coal and waste rock.

[0003] At present, in the process of connecting the existing mine cars with pins, manual unhooking is required, which not only increases the labor intensity of the staff, but also causes a collision accident between people and vehicles if the unhooking is not timely and the mine car travels too fast, threatening personal safety. Utility Model Content

[0004] The utility model aims to solve the problems that the existing manual hook removal requires increased labor intensity of the staff and untimely hook removal causes collision accidents between people and vehicles, and proposes an automatic unhooking device for inclined shaft mine vehicles.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cam is connected with the second end of the second connecting piece, and the second end of the second connecting piece is connected with the second connecting piece by the spring, and the second end of the second connecting piece is connected with the spring, and the other end of the second connecting piece is connected with the second connecting piece by the spring.

[0007] Furthermore, the top of the top cap is an arc-shaped structure.

[0008] Furthermore, the circumferential outer wall of the slip ring is provided with an inclined surface.

[0009] Furthermore, the slip ring is located between the clamping ring and the top cap.

[0010] Furthermore, a control panel is fixedly connected to an outer wall of one side of the mining car body.

[0011] The beneficial effects of the utility model are:

[0012] 1. The installation box and the block are moved downward by the extension of the electric telescopic rod, so that the block is moved to the bottom of the slip ring. Then, the block is moved along the surface of the slip ring to the top of the top cap by the contraction of the electric telescopic rod, so as to realize automatic hook removal and improve safety.

[0013] 2. The installation box is moved downward under the driving force of the electric telescopic rod, so that the top cap and the sliding hole are slidably plugged. The electric telescopic rod continues to stretch to drive the card block to move downward along the arc surface of the top cap until the card block moves to the bottom of the top cap. Under the action of the first spring, the card block pops outward, and then, the installation box and the card block are driven upward by the contraction of the electric telescopic rod, so that the card block is stuck under the top cap, thereby quickly connecting the two mine car bodies.
