Description
Technical field
The utility model relates to a kind of Air Throttle in Mine Pit security control equipment, specifically is a kind of air door blocking device.
Background technology
Air door be cut off under the mine, outgoing airflow, but again can the current a kind of facility of guarantor's car.The mine lower wind door can not be less than twice, and the twice air door can not open simultaneously, otherwise can cause distinguished and admirable short circuit, causes the accident of " an anti-threeway ".What mine used down at present has with the pneumatic door lock of down-hole blast as power, but requires necessary dynamic source, complex structure, operation inconvenience; With the down-hole power is the electric locking of power, needs electric power endlessly; Wheeled backguy locking, but the fiting effect of practical application middle pulley and backguy is poor, comes off easily, thus make locking work unreliable.The patent No. is 98251704 to disclose a kind of colliery air door blocking device, and it is complicated to exist reset case and interlock cross bar to install on its structure, the problem of maintenance inconvenience.
Summary of the invention
The utility model is in order to solve the air door lock construction complexity that exists in the prior art, and installation is overhauled the problem of inconvenience and a kind of air door blocking device is provided.
The utility model is realized by following technical scheme, a kind of air door blocking device, comprise the wire rope that has rope sling, be connected on the lock body at stay cord two ends respectively, lock body comprises the socket that is fixed on the air door, is fixed on the keeper seat on the air door, one end bending of rope sling is fixed on the keeper seat, pass the keeper of keeper seat, stay cord is connected on the keeper, and an end of keeper is with back-moving spring.
In actual applications, fix a lock body respectively on two adjacent air doors, when wherein first air door is opened, because the rotation of door, wire rope is pulled pulling, and the keeper of the connection lock body of the wire rope other end is drawn simultaneously and inserts socket, thereby second air door is by locking.Similarly, open second air door after, first air door is by locking, the result is that two air doors can not be opened simultaneously.
Compared with prior art, the utility model has used keeper and keeper seat to cooperate, and is simple in structure, easy for installation, only utilized the people at the power of opening generation at closing time, do not need extraneous power, safe and reliable, effectively.
