Abstract
The invention relates to a deformation preventing air door under the shaft, and discloses equipment of an air door commonly used under the shaft, which prevents the air door from deformation caused by the pressure on the ventilation door from a top plate. The deformation preventing air door is characterized in that a door frame of the air door is embedded into the upper frame of the door frame, and positions a spring through spring seats fixed in the upper frame and on the door frame to realize the vertical displacement in the door frame of the upper frame, and air current is prevented through an upper wind shield mounted on the upper frame and a lower wind shield mounted on the door frame, so that the normal use of the air door is ensured.
Description
Technical field: the air door of down-hole distortion preventing belongs to the ventilation of the various mining industry such as colliery, iron ore.
Background technology: by comprehensive retrieval underground ventilating air door both domestic and external, be widely used in the various mining industry productions that are positioned at down-hole.Consumption is very large, and because the situation of damaging air door after roof weighting by pressure often occurs, can only in time change or remove maintenance, not only a large amount of manpower and materials had been wasted but also efficiency is not high, safety in production to mine forms very large hidden danger, we are by unremitting effort with developed the air door of down-hole distortion preventing for this reason, look into newly through retrieval, also do not occur invention and creation and the product of same type in the industry.
Summary of the invention: content of the present invention is the problem for above-mentioned existence, in conjunction with present safety in production actual needs, we are by continuous effort and developed the air door of down-hole distortion preventing, look into new through retrieval, innovation and creation and the product of also not finding same type of the same trade, thus that the present invention has realized is convenient and safe, the equipment that prevents efficiently the air door distortion.
Its feature of the air door of down-hole distortion preventing is contained in Compress Spring in the air door upper ledge by the air door top and realizes the upper and lower displacement of air door housing.The air door of down-hole distortion preventing is in the underground ventilating of colliery, after roof weighting, utilizes the Compress Spring that is arranged on the air door top to prevent to damage the ventilation air door by pressure after roof weighting; Use overhead gage by the Compress Spring outside that air door top three is assembled in air door, the inside lower baffle plate, and the spring that is fixed on spring base cuts off distinguished and admirable; After roof weighting, overhead gage is along with the sedimentation of top board relies on the Compress Spring displacement, and lower baffle plate is fixed on the air door wall motionless.Alleviate or eliminate sedimentation after roof weighting with this, making normally carrying out of the indeformable assurance underground ventilating of air door.
The air door of down-hole distortion preventing compared with prior art has the following advantages:
Press if there is back, can not damage air door by pressure during distortion, air door can normally be opened ventilation, guarantees mine safety production.
Description of drawings:
Accompanying drawing is the air door schematic diagram of down-hole distortion preventing.
1, upper ledge 2, spring 3, spring base 4, outer verge board
5, interior verge board 6, doorframe 7, air door
The specific embodiment: now illustrate to the drawings as examples:
The air door of down-hole distortion preventing discloses air door distortion equipment after the prevention roof weighting of a kind of down-hole air door commonly used, upper (1) that the doorframe (6) that it is characterized in that being contained in air door (7) inserts doorframe (6) by be fixed in upper ledge and doorframe on spring base (3) come retainer spring (2) to realize the upper and lower displacement of upper ledge on doorframe, realize blocking distinguished and admirable by the lower verge board (5) that is contained in the upper gear (4) on upper ledge and be contained on doorframe.Guarantee the normal use of air door.
Claims (3)
1. the air door of down-hole distortion preventing is in the underground ventilating of colliery, after roof weighting, utilizes the Compress Spring that is arranged on the air door top to prevent to damage the ventilation air door by pressure after roof weighting.
2. the air door of down-hole according to claim 1 distortion preventing, is characterized in that use overhead gage by the Compress Spring outside that air door top three is assembled in air door, the inside lower baffle plate, and the spring partition that is fixed on spring base is distinguished and admirable.
3. the air door of down-hole according to claim 2 distortion preventing, it is characterized in that after roof weighting, overhead gage is along with the sedimentation of top board relies on the Compress Spring displacement, lower baffle plate is fixed on the air door wall motionless, alleviate or eliminate sedimentation after roof weighting with this, making normally carrying out of the indeformable assurance underground ventilating of air door.
