Embodiment Construction

[0011] As shown in the drawings, the present invention includes a head meeting device and a hook shaft device. The head meeting frame 2 of the head meeting device is fixed on the bottom plate of the mine rail 9 through a pressure plate, and the head meeting frame 2 is hinged to the head 4 through a torsion spring and a shaft. When there is no external force, the top of the mine car 4 is higher than the bottom of the mine car 6, and is aimed at the height of the inclined lane, and the meeting of the mine car stops the mine car from passing through. On the hook shaft frame 8 of the hook shaft device, the hook head 7 is hinged by a powerful torsion spring 10 and a shaft, and the arm of the hook head 7 is locked by the hook shaft frame 8 through the pin shaft 11, so that the top of the hook head 7 is locked by the hook shaft frame 8 when there is no external force. Below the axle shaft of described mine car 6, mine car 6 can be passed through. The pin shaft 11 is hinged to one end...

Abstract

The invention relates to an anti-car-running device for a mine car in a transportation inclined alley of the underground excavation surface of a coal mine. The device comprises a meet device and a hook shaft device, wherein a meet frame of the meet device is fixed on the bottom surface of a track of the mine car through a pressure plate, and hinged with a meet head through a torsion spring and a shaft; without external force, the top end of the meet head is higher than the bottom of the mine car, and is aligned with the top of the inclined alley; a hook shaft frame of the hook shaft device is hinged with a hook head through a powerful torsion spring and a shaft; an arm of the hook head is locked by the hook shaft frame through a hinge pin so that the top end of the hook head is lower than the axle of the mine car in the absence of external force and the mine car can pass through; the hinge pin is hinged with one end of a steel wire rope, and the other end of the steel wire rope is hinged with the meet head; and when the meet head is met, the hook head bounces to hook the axle, and the two devices prevent cars running together, thereby greatly improving the safety performance. The anti-car-running device has a simple structure and is convenient and flexible to use, safe and reliable.

Description

technical field [0001] The invention relates to an anti-running device for a mine car in a transport inclined roadway in an underground mining working face of a coal mine. Background technique [0002] In the inclined transport lanes of the underground mining face of coal mines, there are sports car accidents such as broken ropes and unhooked car returns, which seriously endanger the safety of production. The inclined roadway transportation of the mining face is a temporary transportation, the roadway section is small, the conditions are poor, and the changes are large, so the regular large-scale anti-car device cannot be used. Invention content: [0003] In order to overcome the defects (points) of the prior art, the invention provides a mine car anti-running device, which is simple in structure, safe and reliable. [0004] The technical solution adopted by the present invention to solve the technical problem is: it includes a meeting device and a hook shaft device, the ...
