Insertion-rod-type vehicle stop device for mine

Abstract

The invention relates to an insertion-rod-type vehicle stop device for a mine. The horizontal cross section outline of a stop lever insertion chamber is oval, the horizontal projection of a guide limit hole is located in the horizontal projection range of the stop lever insertion chamber, and a stop lever is movably inserted in the stop lever insertion chamber in the up-down mode and penetrates through the guide limit hole. The lower end of the stop lever is located in the stop lever insertion chamber, the upper end of the stop lever is located above a mounting fixing plate, and the stop leveris hollow and through up and down and simultaneously provided with upward and downward openings. A connection pipe is hinged to the lower end of the stop lever and is through up and down, the upper end of the connection pipe is hinged into the lower end of the stop lever, and a guide limit block is fixedly connected to the lower end of the connection pipe and movably arranged in a stop lever placement cylinder in an up-down mode. The connection pipe penetrates through the guide limit block in an up-down mode, the lower end of the stop lever is provided with a spiral containing groove, the stop lever is upwards lifted relative to the stop lever placement cylinder, the guide limit block abuts against the lower face of the mounting fixing plate, the stop lever is horizontal and is flat placed, and the connection pipe is located in the spiral containing groove.

Description

technical field [0001] The invention relates to a mine device, in particular to a plug-in type mine car stop device. Background technique [0002] In coal mining enterprises, in order to ensure safe production, it is necessary to achieve three gears on one slope, and the third gear includes a car stopper. The stop rod placement tube), the base is installed and fixed on the place where the mine car passes between the two rails, when the car needs to be blocked, the stop rod is inserted into the base, so that the stop rod is in a standing state, and it is used to block the mine car sports car. When driving, the stop bar is pulled out from the base, the track is in an open state, and the mine car can move normally. [0003] In actual operation, after the staff pulls out the baffle rod from the base, they will discard the baffle rod at will. If it bounces up, it is likely to accidentally injure the staff. On the other hand, the irregular random placement of the stopper bar is ...

Problems solved by technology

[0003] In actual operation, after the staff pulls out the baffle rod from the base, they will discard the baffle rod at will. If it bounces up, it is likely to accidentally injure the staff. On the other hand, the irregular random placement of the stopper bar is very likely to stumble other workers passing by here. Third, when the car needs to be blocked again, the stopper bar should be reinserted into the base At this time, the baffle lever that is discarded may not be found in time, thus wasting too much time to find the baffle lever

[0004] In addition, during driving, since the baffle rod is pulled out from the base, the baffle rod placement cylinder in the base is in an upwardly open state. objects, causing the stop rod to not be inserted into the base normally, thus affecting the normal use of the car stop device, so it is necessary to clean up the sundries in the stop rod placement cylinder in time

Because the baffle rod placement cylinder has a certain depth, it is inconvenient for the staff to directly operate, so it is necessary to process tools with long handles, which undoubtedly increases the workload and improves the production cost, and because the baffle rod placement cylinder is deep, even if With a tool with a long handle, it is still inconvenient to operate, time-consuming and labor-intensive, and the cleaning effect is not very good
