Abstract
The utility model discloses a kind of Novel air door---pressure-resistant air door, it is by rubber body of wall (1), concrete wall (2), rotatable door body (3) and be connected rod iron (4) and form.When mine pressure is had an effect, can cause and crush, roadway deformation, thus the air door be arranged in tunnel is damaged, cause and leak out.This pressure-resistant air door is just not fragile, and during roadway deformation, the rubber body of wall (1) of air door can change thereupon, plays a protective role to concrete wall (2) and rotatable door body (3), thus keeps the seal of air door, prevents from leaking out.
Description
Technical field
The utility model relates to mine ventilation field, is directed to ore deposit pressure and easily causes roadway deformation thus damage air door causing the problem of leaking out to design.
Background technology
Air door as facility indispensable in mine ventilation system, its effect mainly: the air quantity that the distinguished and admirable or restriction tunnel in isolated tunnel is passed through, guarantee air quantity of distributing according to need, do not hinder again simultaneously workman or mine car normal through.But due to the existence of mine pressure, usually can roadway deformation be caused, the air door be arranged in tunnel is just very easy to damaged, thus causes leaking out.This will cause mine ventilation system disorderly, reduces drafting efficiency, constitutes a threat to the personal safety of underground operators and normal production of the safety in colliery.
Summary of the invention
For the existence of this phenomenon, the utility model provides a kind of Novel air door---and pressure-resistant air door, it can well be applied to this phenomenon.
The present invention addresses this problem adopted scheme: in the extension of air door, and namely the position that contacts with roadway surrounding rock of air door, arranges certain thickness, better, the resistant to elevated temperatures rubber body of wall of elasticity; Between pivoting door body and rubber body of wall, have the concrete wall of a segment distance, its lower end is a part of below base plate, to play fixing effect; Connection between concrete wall and rubber body of wall is realized by 6 bar-shaped steel, and a part for steel is fixed in concrete wall, and another part is then fixed in rubber body of wall.Require that each junction is airtight stuffy.
The beneficial effects of the utility model are: after mine pressure causes roadway deformation, and the rubber wall part of pressure-resistant air door is out of shape along with the distortion in tunnel, and other rigid body portion of pressure-resistant air door can not be caused to damage, and causes and leaks out.
Accompanying drawing explanation
Fig. 1 is pressure-resistant air door front view.
In the drawings, 1. rubber body of wall, 2. concrete wall, 3. wooden rotatable door body, 4. connect rod iron, 5, the concrete wall in base plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
When mine pressure causes roadway deformation, there is deformation along with the distortion in tunnel in rubber body of wall (1), thus protect concrete (2) and wooden rotatable door body (3), makes air door still keep seal, prevent from leaking out.
Claims (2)
1. a Novel air door---pressure-resistant air door; ore deposit can be tackled well and press the damage that it is caused; it is characterized in that: the extension of air door is rubber body of wall (1); it contacts with country rock; can play a protective role very well when roadway deformation; concrete wall (2) and rotatable door body (3) are remained intact, does not leak out.
2. pressure-resistant air door according to claim 1, its feature comprises: rubber body of wall (1) is connected by rod iron (4) with concrete wall (2); Concrete wall (2) be fixedly arranged by a part of body of wall to realize in the soleplate.
