The pneumatic structure of the utility model can achieve open-close and linkage of the air doors, and the two door leaves are configured in an angle shape when the air doors are closed. The double-leaf pneumatic linkage air door has the advantages of simple structure configuration, safe and reliable operation, good sealing performance, flexible opening/closing, and convenient operation control.
Description
Technical field
The utility model relates to mine ventilation system, is specifically related to a kind of biparting opposite opened pneumatic interlocking air door.
Background technology
Pedestrian in the mine laneway, driving air door are one of main units of ventilation system, and it is one group of twice air door, and with one section tunnel sealing, the twice air door links each other, prevents that two are opened simultaneously, causes the inlet air system short-circuit, causes the mine ventilation accident.Be mainly used in the air door of driving at present, employing places conplane biparting rotation clamshell doors structure, the interlocked control of air door adopts wire rope, pulley to be equipped with the combining structure of heavy iron or spring, its structure configuration is complicated, easily break down and influence the operate as normal of air door, exist the Interlock Reliability energy of air door, the closed performance of door leaf and the relatively poor relatively problem of the flexible performance of unlatching of door simultaneously.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of structure configuration simple, safe and reliable property height, convenient operation and control, closed performance and the good biparting opposite opened pneumatic interlocking air door of the flexible performance of use.
The technical scheme that realizes above-mentioned purpose is: a kind of biparting opposite opened pneumatic interlocking air door, it includes biparting rotation opposite opened first air door and the second air door and the interlocking mechanism of phase configuration, two fan door-plates became outer lobe-shape configuration when its described biparting rotation clamshell doors was closed, match with two door-plates that dihedral configuration is closed and to be provided with the loam cake of triangularity in the doorframe upper end, on loam cake, be provided with horizontal air door and open and close two-way cylinder, be provided with downward spacing vertical pivot matches with the longitudinally guiding groove that places triangle loam cake position of center line in the center of two-way cylinder, the two-piston bar outboard end of its two-way cylinder is hinged with corresponding door-plate separately respectively, at the perpendicular unidirectional cylinder of air door locking that is equipped with the assembling back-moving spring in the anterior angle place of triangle loam cake, the piston-rod lower end of its unidirectional cylinder is equipped with the dihedral jam plate that matches with two door-plate upper corners of closed condition; Its described interlocking mechanism by configuration outdoors, the air pipe line of jettron connects air door and opens and closes the unidirectional cylinder of air door locking on two-way cylinder and the corresponding with it air door and constitute in the door.
The utility model adopts pneumatic structure to finish opening and closing of air door, and realizes interlocking, has the structure configuration simply, and is safe and reliable, the characteristics of convenient operation and control.
The biparting door-plate of the utility model becomes the dihedral configuration in off position, has air door bulk strength height, and closed performance is good, opens and closes flexible characteristic.
Description of drawings
Fig. 1 is this pneumatic interlocking air door scheme of installation in the tunnel;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is this air door structure front view;

The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, this pneumatic interlocking air door have the biparting rotation opposite opened first air door 1 of phase configuration and second air door 2, two air doors in turn the back span certain distance be relatively arranged in the tunnel, constitute the partition distinguished and admirable to the tunnel.Two fan door-plates became outer lobe-shape configuration when the clamshell doors of its air door was closed, match with two door-plates of dihedral configuration and to be provided with the loam cake 5 of triangularity in the doorframe upper end, on loam cake, be provided with horizontal air door and open and close two-way cylinder 6, the center of two-way cylinder is provided with downward spacing vertical pivot and matches with the longitudinally guiding groove 8 that places triangle loam cake position of center line, the two-piston bar front end of two-way cylinder is hinged on the corresponding door-plate respectively with separately, at the perpendicular unidirectional cylinder 7 of air door locking that is equipped with the assembling back-moving spring in the anterior angle place of triangle loam cake, the piston-rod lower end of its unidirectional cylinder is equipped with the dihedral jam plate that matches with two door-plate upper corners of closed condition.The interlocking mechanism of its two air door by configuration outdoors, in the door airduct of jettron 3,4 connect air door open and close two-way cylinder 6 and with it corresponding air door the unidirectional cylinder 7 of air door locking and constitute.During concrete enforcement, its outdoors, in the door jettron 3,4 be installed in respectively the per pass air door outdoors with door in the appropriate location being convenient to operate on the wall of tunnel, both sides.
Accompanying drawing 5 has provided this pneumatic interlocking air door pneumatic locking mechanism pneumatic diagram.The air feed import 9 of its first, second two air doors 1,2 gas circuits is connected to the tunnel wind regime, and by the air feed pipe through threeway connect respectively outdoors, the door in jettron 3,4, its jettron 3,4 is selected the 3-position 4-way air valve, connect the cylinder central authorities and the both sides of two-way cylinder 6 respectively through airduct, have two gears of working that open the door and close the door.The airduct of two-way cylinder middle position is connected to and the unidirectional cylinder 7 of the air door locking of its corresponding air door.
After said structure installation configuration is finished, when entering, press first air door jettron outdoors by first air door side, the first door opening, locking second air door simultaneously, enter the first air door after, press jettron in the first air door door, close the first air door, open second air door locking mechanism simultaneously.By behind the first air door, press jettron in the second air door door, open the second air door, locking first air door by behind the second air door, is pressed second air door switch outdoors simultaneously, closes the second air door, opens the locking mechanism of first air door simultaneously.The operation of operation when in like manner, being entered by second air door side control when being entered by first air door side controlled identical.Thereby be implemented in pedestrian, driving when the tunnel, avoid two air doors to open simultaneously, cause the inlet air system short-circuit and have an accident, guarantee the production safety of mine.
