Abstract
Disclosed is a pressure-resistant pressure-equalizing air door for mines. A door top frame, a door bottom frame and two lateral door frames form a door frame. An arch reinforced beam is disposed on the periphery of the door frame. Two side-hung door leaves are mounted on the door frame through door shafts. A linkage pressure equalizer is connected between the two door leaves. Each door shaft comprises door shaft body and a door shaft seat, the door shaft body is fixed with an upper adjusting fixing hole or a lower adjusting fixing hole of each door leaf through a bolt, the door shaft seat is fixed with an adjusting fixing hole on the door top frame or the door bottom frame through a bolt, and a rotary shaft of the door shaft body is inserted into a door shaft seat fixing hole. By the pressure-resistant pressure-equalizing air door, the single door leaf is capable of equalizing pressure, door leaf opening is more laborsaving, and the overall air door achieves the pressure equalizing effect and pressure-free effect. In addition, the air door is high in tunnel top slope pressure resistance, and smooth opening and closing of door leaves are guaranteed.
Description
Technical field
The utility model relates to a kind of mine resistance to compression and all presses air door, is all pressures air door for mine.
Background technology
All pressures air door that mine is used, the hinge point of door leaf is fixedly installed on the outer end of door leaf, because there is leeway on the door leaf two sides, and is more painstaking when pushing or pulling, for this reason, the interlock voltage balancer is set between two door leafs, during a door leaf opens outward, another door leaf is corresponding inwardly to be opened, and realizes the stress equalization of two door leafs by the interlock voltage balancer, but each door leaf itself and interlock voltage balancer are stressed very large, affect their application life; The pressure of mine laneway top side makes the doorframe distortion easily, affects the switching of door leaf, and does not have at present corresponding solution.
Summary of the invention
The purpose of this utility model provides a kind of mine resistance to compression and all presses air door, further solves self door leaf voltage-sharing, solves the problem that side pressure in top, tunnel is suppressed doorframe the deformation effect air door switch.
The purpose of this utility model realizes as follows: consist of doorframe by head jamb, door underframe and both sides doorjamb, on doorframe, put down the door leaf of opening by door axis device two fans, connect the interlock voltage balancer between two door leafs, door-hinge is made of door-hinge body and door-hinge seat, the door-hinge body is fixed by the adjusting fixing hole of bolt and door leaf top or bottom, the door-hinge seat is fixed by the adjusting fixing hole on bolt and head jamb or the door underframe, and the rotating shaft of door-hinge body is inserted in the door-hinge seat fixing hole.The door-hinge body adjusting fixing hole different from door leaf top or bottom fixed, can the adjustment doors axis body and the distance of door leaf side, adjusting fixing holes different on same door-hinge seat and head jamb or the underframe are fixed, can the adjustment doors axle bed and the distance of doorjamb, the corresponding permanent position of adjusting synchronously door-hinge body and door-hinge seat, can adjust the position, the left and right sides of the pin joint of door leaf, make the blast of the door leaf left and right sides approach balanced when making things convenient for the pedestrian to drive a vehicle as far as possible, avoid each door leaf to bear too large bias voltage, greatly reduced the balance pulling force of interlock voltage balancer.
Be provided with the stiffening girder of arch in the periphery of doorframe, stiffening girder can be combined by 3 sections arc beams, carrying tunnel top side pressure, protection doorframe.
The utility model can make the single door fan have certain equal pressure energy power, and opened door leaf is more laborsaving, makes air door integral body reach the effect of all pressing with no pressure; The ability of the anti-tunnel of air door top side pressure is strong, and it is smooth and easy to guarantee that door leaf opens and closes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model door-hinge.
The specific embodiment
With reference to Fig. 1, Fig. 2, consist of doorframe by head jamb 2, door underframe 4 and both sides doorjamb 3, be provided with the stiffening girder 1 of arch in the periphery of doorframe, on doorframe, put down the door leaf 6 of opening by door-hinge 5 devices two fans, connect interlock voltage balancer 7 between two door leafs 6, door-hinge 5 is made of door-hinge body 8 and door-hinge seat 9, door-hinge body 8 is fixed by the adjusting fixing hole of bolt and door leaf 6 tops or bottom, door-hinge seat 9 is fixed by the adjusting fixing hole on bolt and head jamb 2 or the door underframe 4, and the rotating shaft of door-hinge body 8 is inserted in door-hinge seat 9 fixing holes.
Claims (2)
1. air door is all pressed in a mine resistance to compression, consist of doorframe by head jamb, door underframe and both sides doorjamb, on doorframe, put down the door leaf of opening by door axis device two fans, connect the interlock voltage balancer between two door leafs, it is characterized in that: door-hinge (5) is made of door-hinge body (8) and door-hinge seat (9), door-hinge body (8) is fixed by the adjusting fixing hole of bolt and door leaf (6) top or bottom, door-hinge seat (9) is fixed by the adjusting fixing hole on bolt and head jamb (2) or the door underframe (4), and the rotating shaft of door-hinge body (8) is inserted in door-hinge seat (9) fixing hole.
2. air door is all pressed in mine resistance to compression according to claim 1, it is characterized in that: the stiffening girder (1) that is provided with arch in the periphery of doorframe.
