Description
Technical field
The utility model relates to a kind of mining device, relates in particular to a kind of mine car resistance and stops device.
Background technology
Transportation mode in transportation system under coal mine well is motor traction mine car or hutching normally, no matter take which kind of transportation mode, if control the bad speed of a motor vehicle or brake failure, mine car meeting immediate roof open air door, very easily air door is broken, cause Air escape branch, form directly to miner's life security and threaten, cause heavy economic losses to coal mining enterprise.
In order to protect air door not to be damaged, the countrmeasure adopting mostly at present is before and after air door and installs vehicle barrier rod, but operating sequence is loaded down with trivial details, and operator is easily flurried, is unfavorable for the carrying out of trouble free service.
Utility model content
The utility model, for deficiency, provides a kind of mine car safe and convenient to use resistance to stop device.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of mine car resistance stops device, comprises slide rail, and slide rail is fixedly mounted between two tracks, slide rail is positioned at below track, slide rail and track are orthogonal, it is characterized in that, on slide rail, left and right slidably connects left slider and right slide block, above left slider, be fixedly connected with left block, left block is " L " shape, and the free end of left block stretches to the track in left side, is fixedly connected with right block above right slide block, right block is also " L " shape, and the free end of right block stretches to the track on right side; The right front ends of left slider is hinged with left connecting rod, the left front end of right slide block is hinged with right connecting rod, left connecting rod and right connecting rod are symmetrical set, the other end of left connecting rod and the other end of right connecting rod are hinged and connected, between the hinge-point of left connecting rod and right connecting rod and the mid point of slide rail, be fixedly connected with extension spring, the hinge-point place of left connecting rod and right connecting rod is also connected with chain rope, and chain rope is connected with air door transmission.
The utility model is installed in per pass air door two ends on the track of 3 meters of air doors, be connected as a single entity by chain rope and air door, when air door is not opened in normally off.Electrical machinery plant's traction mine car or hutching are to air door, and this resistance stops device and can stop vehicle to advance, if will continue operation, must stop, and first open air door, and only, after air door is opened completely, resistance stops device just can open completely, and vehicle just can pass through.After vehicle passes through, air door is closed, and resistance stops device and recovers normally off, and air door is effectively protected, and prevents from being damaged, and has stopped Air escape branch, can ensure the stable of ventilation system, and therefore the utility model is safe and convenient to use.
