Description
[technical field]
The utility model relates to a kind of coal mine ventilation door pressure relief, especially relates to a kind of air door pressure relief device.
[background technology]
Known, mine ventilation refers to be inputted air under mine, to increase the concentration of oxygen in mine and to reduce gas harmful in mine; The basic task of mine ventilation is: supply with the enough fresh airs in down-hole, meet the needs of personnel to oxygen; Water down down-hole toxic and harmful and dust, ensure safety in production; Regulate down-hole weather, create good working environment.In order to make down-hole distinguished and admirable along fixed route flow distribution, the structure that just must build guiding airflow regulation in some tunnel are ventilation equipment, and air door is namely installed, and by air door, by being divided in mine, guiding is distinguished and admirable and partition is distinguished and admirable.Ore deposit, He Nanguo village belongs to highly gassy mine, mine air-required volume is large, mine ventilation negative pressure is large, the large air door of the indivedual pressure reduction in a down-hole often people is difficult to open, sometimes also can generation personnel be trapped in the middle situation of air door, increase great difficulty by air door to pedestrian, the mistake car of mine, affected greatly safety and the production efficiency of mine.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of air door pressure relief device, slowly open release pressure by ring-type rocking handle by the screw control verge board in screw rod, cross plate, effectively overcome the drawback of door opening difficulty.
For achieving the above object, the utility model adopts following technical scheme:
A kind of air door pressure relief device, comprise air door, venting ring, verge board, screw rod and ring-type rocking handle, on air door, be provided with large opening, venting ring is fastened on described large opening, middle part at venting ring is provided with cross plate, four plate body outer ends of described cross plate connect the inwall of venting ring, between four plate bodys by cross plate, form air port; Middle part in cross plate is provided with screw, and screw rod is flexibly connected described screw, is provided with ring-type rocking handle on the screw rod of air door outside, and the screw rod of described air door inside is provided with verge board.
Described air door pressure relief device, the outer rim of described venting ring is circular configuration.
Described air door pressure relief device, the inner face middle part of described verge board is provided with protruding platform, and cottor pin is fixed on air door one end of screw rod on the protruding platform of verge board.
Described air door pressure relief device, the middle part of described cross plate is towards ring-type rocking handle one side projection.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
Air door pressure relief device described in the utility model, by changing existing air door, on existing air door, open a round mouth, use has the venting ring of certain degree of hardness and thickness by being welded to connect on air door round mouth, screw rod is through on the screw of venting ring middle part cross plate, the inside and outside two ends of screw rod arrange respectively verge board, ring-type rocking handle, and while closing air door, verge board is buckled on the air port of venting ring, need to open air door time, slowly open release pressure by ring-type rocking handle by screw rod control verge board and just can; The utility model is simple in structure, can effectively overcome the drawback of door opening difficulty.
