The content of the invention
Present invention seek to address that above mentioned problem, can quick and precisely reset, simple structure, internally-arranged type structure so as to provide one kind
Make, occupy little space, the mine ventilation explosion-proof well cover device of convenient and flexible operation.
The present invention solves described problem, and the technical scheme of use is：
A kind of mine ventilation explosion-proof well cover device, including returnairshaft, well lid, returnairshaft is interior to be provided with ring-shaped groove, well lid
Lower end is connected with least three back-moving springs being evenly arranged, and each back-moving spring other end is connected with one and ring-shaped groove phase
The fixture block of adaptation, well lid center, which runs through, the torque arm stretched into returnairshaft, and torque arm is located at the upper and lower part in returnairshaft
The opposite external screw thread of hand of spiral is respectively equipped with position, a pushing ring is respectively equipped with the external screw thread of upper and lower part, is pushed away
Enter ring to be flexibly connected with corresponding fixture block by pushing ram respectively.
Using the present invention of above-mentioned technical proposal, compared with prior art, the characteristics of it is protruded, is：
1. can fast and accurately be automatically reset, while it can also quickly realize effective closure of return air well head.
2. internally-arranged type constructs, simple structure, occupy little space, convenient and flexible operation.
Preferably, the further technical scheme of the present invention is：
Torque arm top is provided with clamp flange, and buffer spring is set with the position that torque arm is located at outside returnairshaft.
Back-moving spring sets three.
Pushing ram both ends are hinged by movable axis with corresponding fixture block and pushing ring respectively.
The uphole end of returnairshaft is provided with ring packing liquid bath.
Brief description of the drawings
Fig. 1 is structural representation of the embodiment of the present invention；
Fig. 2 is the partial enlarged drawing of A in Fig. 1；
In figure：Clamp flange 1；Torque arm 2；Ring packing liquid bath 3；Uphole end 4；Pit shaft 5；Ring-shaped groove 6；Pushing ram 7；
Pushing ring 8；Buffer spring 9；Well lid 10；Back-moving spring 11；Fixture block 12；External screw thread 13；Movable axis 14.
Embodiment：
With reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands present invention, because
This, the cited case is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, the uphole end 4 of returnairshaft is provided with ring packing liquid bath 3, and sealing is filled in ring packing liquid bath 3
Liquid, the pit shaft 5 of returnairshaft is interior to be provided with ring-shaped groove 6, in case being used during installation fixture block 12, the lower end of well lid 10 is connected with three uniformly
The back-moving spring 11 of arrangement, each other end of back-moving spring 11 are connected with a fixture block 12, and three fixture blocks 12 are uniformly distributed and divided
It is not correspondingly arranged with ring-shaped groove 6, the torque arm 2 having in the pit shaft 5 for stretching into returnairshaft is run through at the center of well lid 10, and torque arm 2 pushes up
End is provided with clamp flange 1, buffer spring 9 is set with the position that torque arm 2 is located at outside pit shaft 5, torque arm is located in pit shaft 5
The opposite external screw thread 13 of hand of spiral is respectively equipped with the position of upper and lower part, is respectively equipped with the external screw thread 13 of upper and lower part
One pushing ring 8, the pushing ring 8 of upper and lower part are flexibly connected by pushing ram 7 with corresponding fixture block 12 respectively, each to promote
The both ends of bar 7 are be hinged by movable axis 14 and corresponding fixture block 12 and pushing ring 8 respectively.
During installation, the present apparatus is put into the pit shaft 5 of returnairshaft first, then rotational fastener flange 1, the middle and upper part of pit shaft 5
External screw thread 13 of the pushing ring 8 along top walk downward, the external screw thread 13 of the pushing ring 8 of bottom along bottom is up walked, then
Pushing ram 7, which merges, to be extruded into fixture block 12 in ring-shaped groove 6 and fixes.After well shooting, be hit wave action, by the bullet of well lid 10
Rise, realize under the collective effect of back-moving spring 11 and buffer spring 9 after pressure release and fast and accurately reset, while quick realization
Effective closure of returnairshaft uphole end 4, so as to ensure that ventilation is normal.
The present apparatus can fast and accurately be automatically reset, while can also quickly realize having for returnairshaft uphole end 4
Effect closure, is constructed using internally-arranged type, simple structure, occupied little space, convenient and flexible operation.
Preferably feasible embodiment of the invention is the foregoing is only, not thereby limits to the interest field of the present invention,
All equivalence changes made with description of the invention and its accompanying drawing content, it is both contained within the interest field of the present invention.
