Description
Technical field
The present apparatus is related to a kind of mining door more particularly to a kind of underground protecting against shock relief damper.
Background technique
Air door is the important structures in mine ventilation system, its partition is distinguished and admirable, creates item for mine air distribution according to need
Part, while being provided conveniently for pedestrian and transport again.Nowadays, with the continuous development and progress of technology, it is numerous style has been emerged
More various air doors, air door can normal use be related to the safety in production of mine.In coal mine actual environment, work is dug close to big gun
Make face or the easy influence by shock wave of bump zone damper, causes air door deformation, damage, in some instances it may even be possible to lead to air door
Can not normal use, cause distinguished and admirable disorder.Shock wave can be also generated when coal-dust explosion or gas explosion occur for mine destroys wind
Door etc. ventilation equipments, for prevention air door be hit wave destroy, we have designed and produced protecting against shock relief damper.
Summary of the invention
The object of the present invention is to provide a kind of protecting against shocks for preventing underground air door from being destroyed by shock wave
Relief damper, to achieve the goals above, the technical solution of the present invention is as follows: protecting against shock relief damper, including doorframe, feature
It is hingedly to be provided with door leaf in doorframe, the air door switch device of control door leaf is provided on door leaf, pressure release is installed on door leaf
Window, the pressure release window are mounted on door leaf by pressure release window rotating assembly.The pressure release window rotating assembly includes axis, pressure release
For window by being articulated and connected between rotation cage plate and axis, rotation cage plate side is equipped with fixed cage plate, rotates to be provided on cage plate and let out
Pressing spring, pressure release spring one end are fixedly connected with rotation cage plate, and the pressure release spring other end is fixedly connected with door leaf.The pressure release
The periphery of window is inlaid with rubber pad.The fixation cage plate is arranged with retaining ring, is equipped with pin shaft under retaining ring, in the doorframe
Two fan door leafs are installed, are provided with pressure release window on each door leaf.
The present apparatus be dedicated to solve down-hole non-pressure damper destroyed by shock wave, solve air door because by
Shock wave alleviates manual maintenance dynamics, extends air door service life to influence the stable problem of ventilating system.For
Mine provides stable ventilating system, effectively guarantees safe production, and fundamentally prevents the generation of accident, guarantees mine ventilation
Essential safety improves mine anti-accident ability.

Specific embodiment
The present invention is further detailed with reference to the accompanying drawings of the specification, protecting against shock relief damper is in original no pressure
It is transformed on the basis of air door, is stayed below door leaf observation window and set pressure release window, rubber pad is inlayed on pressure release window periphery.Door leaf passes through
Pressure release window rotating assembly is connect with pressure release window, and spring is installed in shaft, makes pressure release window without impact or external force condition by spring
It is lower to be contacted with fan tightly, it does not leak out.When pressure release window is being opened simultaneously pressure release by shock wave or external force, to protect
Air door is not hit destruction, and spring closes pressure release window after pressure release, separates distinguished and admirable, ensure that the stabilization of ventilating system, is mine
Well safety in production provides safeguard.
Be according to the protecting against shock relief damper device characteristic: system structure is simple, installation easy to process, and technical requirements are low.
System is easy to maintain, highly reliable.
The realization of this covering device is simultaneously with the following functions: passing through pressure release window pressure release after realizing the air door effect of being hit, effectively
The intact and ventilating system that ensure that air door stabilization.
When protecting against shock air door is impacted, shock wave opens air door pressure release window, releases pressure, after pressure release,
The spring acted between pressure release window and air door closes pressure release window, so that air door is not hit, the destruction of wave plays self and protects
Shield, while guaranteeing that ventilating system is reliable and stable.
