Abstract
The invention relates to an air door used under a coal well, in particular to an air type lockout biparting air door which solves the technical problems that a current mining air door cannot be used normally under the situations that power is off and wind stops being supplied, and cost is high. The air type lockout biparting air door comprises a pair of biparting air door bodies which are sequentially arranged in a tunnel. In each biparting air door body, the outer side face of one air door body is connected with a door frame adjacent to the air door body through a first air cylinder and a support connected with the first air cylinder; in each biparting air door body, the position, close to the upper door frame, of the inner side face of one air door body is vertically provided with a second air cylinder. A blocking rod is arranged in one biparting air door body, the air cylinders play a role of locking, the two biparting air door bodies cannot be opened at the same time, the locking purpose can be achieved in any environments and conditions, the adaptability is strong, installing and using are very simple, and locking is reliable and stable.
Description
Technical field
The present invention relates under colliery use air door, be specially the biparting air door of a kind of air type locking.
Background technology
Colliery normally used pressure wind formula air door locking, the locking of electrodynamic type air door and fluid pressure type throttle locking device must could bring into play normally the locking effect under given conditions and installation cost high, regular maintenance difficulty and workload are large, can't normally use during the power failure blowing-out.Therefore need a kind of locking effect and air door with low cost still can brought into play under power failure blowing-out state.The most frequently used air door structure is that twice are arranged on the biparting air door between tunnel inner wall 10 in turn at present, each biparting air door comprises a doorframe 3, be provided with a pair of air door by rotating shaft in doorframe, the lateral surface of two air doors is provided with handle 11, be used for air door is pulled open laterally, air door can only pull laterally, because stopping of doorframe can not turn to the inside.
Summary of the invention
The present invention, for solving the technical problem that present colliery can't normally be used in power failure blowing-out situation with air door and cost is higher, provides a kind of air type locking air door.
The present invention realizes by the following technical solutions: the biparting air door of a kind of air type locking comprises a pair of biparting air door that is arranged in turn in tunnel; The lateral surface that an air door arranged in the biparting air door of per pass is connected by the contiguous doorframe of first cylinder and the support that is connected with the first cylinder and this air door; The movable end of described the first cylinder is hinged by the lateral surface of the first hinge and air door, and the fixed end of the first cylinder is hinged on an end of support by the second hinge; The other end of support is fixed on doorframe; Have the position of the close top of the medial surface doorframe of an air door vertically to be provided with second cylinder in the biparting air door of per pass, up, the lateral surface of this air door is fixed with a barrier plate to the movable end of described the second cylinder; The part of barrier plate is stretched out this air door and is cantilever construction; The air inlet port of the first cylinder of the biparting air door of described per pass is connected and forms the circulation gas circuit by pipeline with gas outlet and the air inlet port of the second cylinder of another biparting air door in road with gas outlet.
Outwards open biparting air door (the biparting air door of below in figure as shown in Figure 2) together by handle in use, the movable end that is connected to the first cylinder between an air door and doorframe shrinks, the first cylinder is around two hinge through, the biparting air door in this road is opened, gas in the first cylinder is compressed into the second cylinder of another biparting air door in road by the circulation gas circuit, the movable end of the second cylinder protrudes upward over doorframe, the air door that the biparting air door of second is equipped with the second cylinder blocks, and makes this air door can't be opened (the biparting air door on Fig. 2 top).The barrier plate that is cantilever construction that is arranged on the air door lateral surface that the second cylinder is housed is used for another is not arranged the air door pinning of the second cylinder, when the biparting air door in Dang Gai road was lockable, the air door that this air door that the second cylinder is not set is equipped with the second cylinder pinned and can't be pulled by barrier plate.Stretch out when closing the movable end of the first cylinder of the biparting air door in biparting air door Hou，Gai road together, this first cylinder of gas inject in the second cylinder of another biparting air door in road, the movable end of the second cylinder of another biparting air door in road shrinks, lock release.Between first, second cylinder, the known technology that is connected to those skilled in the art of circulation gas circuit, be easy to realize.
The present invention is by playing the effect of locking at the biparting air door installation of per pass countercheck rod, cylinder, can guarantee that the biparting air door of twice can not open simultaneously, all can play the locking effect under any environment and condition (as the power failure blowing-out), applicability is strong, installation and use are very simple, and locking is reliable and stable.

The specific embodiment
The biparting air door of a kind of air type locking, comprise a pair of biparting air door that is arranged in turn in tunnel; The lateral surface that an air door 1 arranged in the biparting air door of per pass is connected by the contiguous doorframe 3 of first cylinder 2 and the support 4 that is connected with the first cylinder 2 and this air door; The movable end of described the first cylinder 2 is hinged with the lateral surface of air door by the first hinge 5, and the fixed end of the first cylinder 2 is hinged on an end of support 4 by the second hinge 6; The other end of support 4 is fixed on doorframe 3; Have the position of the close top of the medial surface doorframe of an air door 1 vertically to be provided with second cylinder 7 in the biparting air door of per pass, up, the lateral surface of this air door 1 is fixed with a barrier plate 8 to the movable end of described the second cylinder 7; The part of barrier plate 8 is stretched out this air door 1 and is cantilever construction; The air inlet port of the first cylinder 2 of the biparting air door of described per pass is connected and forms the circulation gas circuit by pipeline with gas outlet and the air inlet port of the second cylinder 7 of another biparting air door in road with gas outlet.
What the biparting air door of per pass was installed the first cylinder 2 and the second cylinder 7 is same air door.As shown in Figure 2, for being installed, more unified convenience generally the first cylinder 2 and the second cylinder 7 are arranged on same air door.
Described barrier plate 8 is to be fixed on air door by bolt 9; The position corresponding with the second cylinder 7 movable ends, doorframe 3 tops is provided with the Yi Ge center and has the snap close 12 in the hole of with the second cylinder 7 movable ends, matching.The movable end of the second cylinder 7 protrudes upward in the hole that enters snap close 12 as shown in Figure 3, with air door 1 locking.
The movable end of the second cylinder 7 can pass snap close 12, makes locking more reliable.
Situation during the movable end of the second cylinder 7 uses according to reality arranges, to guarantee that air door can be locked.
