The gas grade of the temple mine is coal and gas outburst mine, and along with the development of the mine, an outburst prevention air door needs to be built on each tunneling working face and needs to be used in a large amount. As shown in fig. 1, when the original anti-sudden air door is built; the outburst prevention air door cannot meet the requirement for normal carrying of the unit, inconvenience is brought to a tunneling team group, certain influence is caused to auxiliary transportation of a mine, and the labor intensity of workers is increased. The outburst prevention air door adjusting window is adjusted by the inserting plate, and the plate needs to be nailed or taken out every time of adjustment, so that the operation is inconvenient. If a large-size outburst prevention air door is built in a roadway, the size of an adjusting window on an air door frame is required to be reduced, the ventilation requirement of a tunneling working face cannot be met, the ventilation system of the tunneling working face is influenced to be stable and reliable, and after a large-size door leaf is used practically, the air door is difficult to open by personnel and vehicles due to the influence of mine negative pressure.

The sizes of various units and vehicles are comprehensively considered, and outburst prevention air doors used in mines are combined, so that the requirements of the units of a tunneling team and the vehicles for entering and exiting are met, the air distribution requirement of a tunneling working face is met, and the passing of the units and the vehicles can be met; but the adjustment of the window area does not meet the ventilation requirements. If the existing outburst-prevention air door is used, the position of the air door is brushed at the bottom, and the requirement of installing and adjusting the air window can be met, so that the engineering quantity of the air door is increased.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the protruding air door is prevented to adjustable amount of wind has overcome the not enough of prior art existence, provides an adjustable amount of wind that the air door is opened in a flexible way, the door leaf size is big and prevents protruding air door.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides an abrupt air door is prevented to adjustable amount of wind, includes the door leaf, is equipped with the air regulation window on the door leaf, is equipped with the door closer above the door leaf, is equipped with a telescopic cylinder in the door closer, is equipped with the control valve in the pneumatic control case, and the valve body and the cylinder of control valve are linked together, and the control end of control valve links to each other with the button that sets up on the pneumatic control case.

Furthermore, the air volume adjusting window comprises two window sashes capable of being pushed and pulled along a slide way, the window sashes are provided with handles, the slide way is provided with adjusting holes which penetrate through the window sashes, and the adjusting holes are used for fastening the window sashes by using bolts.

The door opening and closing device further comprises a first pull switch and a second pull switch, wherein the first pull switch is respectively connected with the control end of the control valve and the door opening pull rope, and the second pull switch is respectively connected with the control end of the control valve and the door closing pull rope.

And the water discharging device is connected with the control valve through an air pipe.

Compared with the prior art, the utility model following beneficial effect has.

The utility model discloses in because single air door weight increase, personnel open and cause certain difficulty, increased a big shortcoming for the air door after reforming transform, to this shortcoming install pneumatic means on preventing suddenly the air door, realize pneumatically opening, solved this difficulty, reform transform back personnel and vehicle through safer and more reliable, have practical use and worth, air volume regulation window regulation air volume easy operation, it is fixed firm, safe simple, labour saving and time saving.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 2 and 3, the utility model relates to an outburst-proof air door with adjustable air volume, which is designed in a split manner, and comprises two door leaves 3, wherein the width of each door leaf 3 is 2.1 meters, and the height of each door leaf is 2.85 meters. The air volume adjusting window 5 is arranged on the door leaf 3, the door closer 8 is arranged on the door leaf 3, the telescopic cylinder is arranged in the door closer 8, the control valve is arranged in the air control box 11, the valve body of the control valve is communicated with the cylinder, and the control end of the control valve is connected with the button arranged on the air control box 11. The number of the buttons is two, one is used for opening the door, and the other is used for closing the door.

As shown in fig. 4 and 5, the air volume adjusting window 5 includes two window sashes 51 that can be pushed and pulled along a slide 54, the window sashes 51 are provided with handles (52), the slide 54 is provided with adjusting holes 53 that penetrate through, and the adjusting holes 53 are used for fastening the window sashes 51 by using bolts. Therefore, the opening of the window sash 51 can be conveniently adjusted, and the ventilation air quantity can be controlled.

As an embodiment, the utility model discloses still include water drain 12, first cord switch 9 and second cord switch 10, first cord switch 9 links to each other with the control end of control valve and the stay cord 13 that opens the door respectively, and second cord switch 10 links to each other with the control end of control valve and the stay cord 14 that closes the door respectively.
