Compound car stop for mine construction

Abstract

The invention discloses a compound car stop for mine construction, and belongs to the technical field of car stops. The compound car stop comprises side connecting plates, wherein two symmetrically arranged connecting frames are fixedly mounted between the side connecting plates; symmetrically distributed fixing mechanisms are arranged on the two sides of the top end of each connecting frame; track bodies are detachably arranged between the adjacent fixing mechanisms; symmetrically arranged fixing frames are fixedly installed on the two sides of the upper end of each connecting frame; fixing barrels are integrally formed on the fixing frames; and first rotating rods are rotationally connected between the adjacent fixing barrels in an inserted mode. The tail end of each track body sequentially penetrates through the corresponding Z-shaped plates, then the side connecting plates can be fixed to the ground, the multiple nuts are sequentially screwed till the nuts are tightly attached to the Z-shaped plates, and therefore the track body is fixed to the connecting frame, and in cooperation with the guide rods, the connecting stability between the track body and the connecting frame can be effectively improved, and the phenomenon of nut looseness caused by repeated collision of a follow-up mine car with the special-shaped car stopping block is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle arresters, in particular to a compound vehicle arrester for mine construction. Background technique [0002] The car arrester, also known as the parking device, is one of the important facilities of the coal mine transportation system and belongs to the anti-car device. On the one hand, the vehicle stop device restricts the mine car to stay at the specified position, on the other hand, it is used to prevent sports car accidents, and is often used in conjunction with equipment such as carts. [0003] There are still certain deficiencies in the compound car arrester used in the current mine construction. For example, most of the existing compound car arresters only use a group of shock-absorbing springs to buffer and absorb the special-shaped car stop block, resulting in the impact of the special-shaped car stop block on the mine. The reaction force produced by the car is relatively large, and the ...

[0003] There are still certain deficiencies in the compound car arrester used in the current mine construction. For example, most of the existing compound car arresters only use a group of shock-absorbing springs to buffer and absorb the special-shaped car stop block, resulting in the impact of the special-shaped car stop block on the mine. The reaction force produced by the car is relatively large, and the mine car cannot be intercepted smoothly, and it will cause great damage to the compound car arrester, thereby reducing the service life of the compound car arrester, and most of the existing compound car arresters only pass through The threaded rod and the nut are used to fix the track, which will cause the nut to loosen after the mine car hits the special-shaped block for many times during subsequent use. In addition, there is no buffer on the special-shaped block of the existing compound car stop mechanism, so that the impact force of the mine car on the special-shaped block is greater, and it is easy to cause damage to the special-shaped block
