Technical field
The utility model relates to air door lock-out techniques field, specially a kind of coalmine ventilation air door New locking device.
Background technique
Air door be for underground pedestrian, driving and be arranged, while guaranteeing that pedestrian, driving underground are current, avoid the occurrence of wind
Flow short-circuit, to guarantee the reliability service of entire ventilating system.The air door of mine be usually by two sects cooperate to using
, when a sect is opened, another sect is in close state, and cannot be opened simultaneously at two sect of moment, to prevent from producing
Raw Air escape branch phenomenon.Currently, twice are realized generally by the wirerope being connected between two doors in two sects in air door
The mutual lock-in control of door can tense wirerope when a sect fully opens, so that another sect can be made in Wire pulling
It is firmly tightened up and is tightly in close state down, so that two air doors will not be in the open state simultaneously.
But when the work of existing air door, since the pulling realization that two sects of air door only pass through steel cable is mutually closed
Lock, when a sect is in semi-open state, then another sect may also will appear semi-open phenomenon, just will appear twice at this time
Door is in semi-open state simultaneously, can not so as to cause forming Air escape branch between two sects or portable blower circulated air phenomenon occur
Effectively guarantee the mutual locking at two sects, the reliability of air door being mutually latched is poor, brings peace for the normal operation of mine
Full hidden danger；Since the total length of locking wirerope has to be larger than length when two sects are closed, the opening of air door just can guarantee, because
This, after existing two sect is opened and closed, the locking wirerope for always having one of air door cannot automatically restore to tension, more
The wirerope of remaining length can stretch the inboard for being attached to a wherein sect, and when opening the sect, extra locking wirerope is given
Pedestrian makes troubles and security risk, is easy to scrape other positions on the head of people and body, leads to casualty accident.
