For achieving the above object, the technical solution adopted in the utility model is: a kind of counterweight air door interlocking control device, comprise two supports, each support internal fixtion is connected with sleeve pipe, it is characterized in that: each sleeve pipe is built with counterweight, counterweight upper end is fixedly connected with stay cord, and each stay cord top is fixedly connected with limit buckle, is provided with balance component between sleeve pipe.
In this structure, described balance component comprises parallel fulcrum lever, parallel fulcrum lever upper end is fixedly connected with limiting plate, parallel fulcrum lever lower end is fixedly connected with parallel-plate, parallel-plate is connected with support plate by bolt, parallel fulcrum lever and limiting plate junction are positioned at the centre position of limiting plate, and the junction of parallel fulcrum lever and parallel-plate is positioned at the centre position of parallel-plate.
In this structure, described limiting plate has spacing breach to both sides, and spacing breach is corresponding with described limit buckle.
In this structure, described two supports are parallel to each other, and each support is the angle-iron frame to internal recessing.
In this structure, described sleeve pipe front surface and rear surface are fixedly connected with front support muscle and rear support muscle, and described balance component is between front support muscle and rear support muscle.
In this structure, described parallel-plate is positioned at the fluting of angle-iron frame.
In this structure, described two counterweights are positioned at above parallel-plate, and two counterweights lay respectively at the both sides of bolt.
In this structure, the weight of described two counterweights is identical.
The utility model has the advantages of and be: due to this structure of the present utility model, so use the utility model can realize the reliability locking of air door, can guarantee that mine ventilation system is stablized, avoid Air escape branch, effectively avoid the generation of the great logical accident prevention in colliery, guarantee that mine ventilation system is reliable and stable.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in Figure 1,2,3, 4, a kind of counterweight air door interlocking control device, comprise two supports 2, each support 2 internal fixtion is connected with sleeve pipe 5, it is characterized in that: each sleeve pipe 5 is built with counterweight 7, counterweight 7 upper end is fixedly connected with stay cord 6, and each stay cord 6 top is fixedly connected with limit buckle 12, is provided with balance component 8 between sleeve pipe 5.In the present embodiment, described balance component 8 comprises parallel fulcrum lever 4, parallel fulcrum lever 4 upper end is fixedly connected with limiting plate 1, parallel fulcrum lever 4 lower end is fixedly connected with parallel-plate 9, parallel-plate 9 is connected with support plate 11 by bolt 10, parallel fulcrum lever 4 and limiting plate 1 junction are positioned at the centre position of limiting plate 1, and parallel fulcrum lever 4 is positioned at the centre position of parallel-plate with the junction of parallel-plate 9.In the present embodiment, described limiting plate 1 has spacing breach 13 to both sides, and spacing breach 13 is corresponding with described limit buckle 12.In the present embodiment, described two supports 2 are parallel to each other, and each support 2 is the angle-iron frame to internal recessing.In the present embodiment, described sleeve pipe 5 front surface and rear surface are fixedly connected with front support muscle 3 and rear support muscle, and described balance component 8 is between front support muscle 3 and rear support muscle.In the present embodiment, described parallel-plate 9 is positioned at the fluting of angle-iron frame.In the present embodiment, described two counterweights 7 are positioned at above parallel-plate, and two counterweights 7 lay respectively at the both sides of bolt.In the present embodiment, the weight of described two counterweights 7 is identical.
When using the utility model, two counterweights are up and down in sleeve pipe, drive stay cord moves, when one air door is opened, a counterweight is driven to rise, balance component disequilibrium, askew to opposite side, the counterweight of the opposite side air door made can not rise, and the air door of such opposite side just can not be opened, thus realizes locking.Only when this road air door is closed, open air door lateral balance hammer declines, and drives balance component to get back to middle equilbrium position, just can open another road air door.This device can realize the reliability locking of air door, avoids artificially starting twice air door simultaneously and causes Air escape branch, guarantee that mine ventilation system is reliable and stable.
This device material therefor is leftover bits and pieces in machining, draws materials convenient and saves material, is conducive to two and carries one and fall carrying out of work.This device is reliable and stable in actual applications, does not limit by conditions down-hole, and can be generalized to all air doors in down-hole, application prospect is extensive.
Through in exploiting field, down-hole hedging chamber in-site installation experimental applications, both prevented air door from leaking out, and facilitated again pedestrian and vehicle to pass through, and can play preferably and control air door leakage wind action, improve ventilation efficiency, obtain good actual effect.If do not used this device, 232 exploiting field hedging chambers need build a set of non-pressure damper airflow regulation again by laying bricks or stones, not only do not meet hedging chamber and build requirement by laying bricks or stones, and waste money of taking a lot of work, only this place is just saved and is dropped into air door fund more than 2.8 ten thousand yuan, saves man-hour more than 30.
