Including the return air well, the well lid, be equipped with annular slot in the return air well, the well lid lower extreme is connected with the three reset spring who evenly arranges at least, every reset spring other end is connected with a fixture block that suits with annular slot, the well lid center is run through has the torsion bar that stretches into in the return air well, the torsion bar is located the external screw thread that is equipped with screw thread opposite direction on upper portion and the lower part position of return air well respectively, it impels the ring to be equipped with one on the external screw thread of upper portion and lower part respectively, impel and encircle the fixture block swing joint who passes through the pushing ram and correspond respectively. The utility model discloses the installation is convenient fast, can operate and accomplish the installation at well head external rotation tightening flange, can effectively guarantee personnel's security, in addition, can also realize after the explosion that quick, accurate carries out automatic re -setting, can also realize effective shutoff of return air well head simultaneously fast, built -in type structure, and the structure is simple and easy, and occupation space is little, flexibility easy and simple to handle.
Description
Technical field
This utility model relates to mining ventilation well lid, specifically a kind of mine ventilation explosion-proof well cover device.
Background technology
Existing Antiexplosive manhole cover exists and can not reset fast and accurately, it is impossible to quickly realizing effective closure of return air well head, and apparatus structure is complicated, great majority construct for externally positioned type, and floor space is big, complex operation step.
Utility model content
This utility model aims to solve the problem that the problems referred to above, thus provide a kind of can quick and precisely reset, simple structure, internally-arranged type structure, take up room little, the mine ventilation explosion-proof well cover device of convenient and flexible operation.
This utility model solves described problem, the technical scheme is that
A kind of mine ventilation explosion-proof well cover device, including returnairshaft, well lid, ring-shaped groove it is provided with in returnairshaft, well lid lower end connects the back-moving spring having at least three to be evenly arranged, each back-moving spring other end connects a fixture block adapted with ring-shaped groove, well lid center is run through the torque arm stretching in returnairshaft, torque arm is positioned on the position, upper and lower of returnairshaft and is respectively equipped with the external screw thread that hand of spiral is contrary, being respectively equipped with a pushing ring on the external screw thread of upper and lower, pushing ring is flexibly connected with corresponding fixture block by pushing ram respectively.
Using this utility model of technique scheme, compared with prior art, its prominent feature is:
1. can automatically reset fast and accurately, can also quickly realize effective closure of return air well head simultaneously.
2. internally-arranged type structure, simple structure, take up room little, convenient and flexible operation.
As preferably, this utility model further technical scheme is:
Torque arm top is provided with clamp flange, and torque arm is positioned on the position outside returnairshaft and is set with buffer spring.
Back-moving spring arranges three.
Pushing ram two ends are hinged with corresponding fixture block and pushing ring by movable axis respectively.
The uphole end of returnairshaft is provided with ring packing liquid bath.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram；
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.
Detailed description of the invention:
Below in conjunction with embodiment, the utility model is described in further detail, and purpose is only that and is more fully understood that this utility model content, and therefore, the cited case is not limiting as protection domain of the present utility model.
nullSee Fig. 1、Fig. 2，The uphole end 4 of returnairshaft is provided with ring packing liquid bath 3，Sealing fluid is filled in ring packing liquid bath 3，It is provided with ring-shaped groove 6 in the pit shaft 5 of returnairshaft，In case using when installing fixture block 12，Well lid 10 lower end connects three back-moving springs being evenly arranged 11，Each back-moving spring 11 other end connects a fixture block 12，Three fixture blocks 12 are uniformly distributed and are correspondingly arranged with ring-shaped groove 6 respectively，The torque arm 2 having in the pit shaft 5 stretching into returnairshaft is run through at well lid 10 center，Torque arm 2 top is provided with clamp flange 1，Torque arm 2 is positioned on the position outside pit shaft 5 and is set with buffer spring 9，Torque arm is positioned on the position, upper and lower of pit shaft 5 and is respectively equipped with the contrary external screw thread of hand of spiral 13，A pushing ring 8 it is respectively equipped with on the external screw thread 13 of upper and lower，The pushing ring 8 of upper and lower is flexibly connected with corresponding fixture block 12 by pushing ram 7 respectively，Each pushing ram 7 two ends are hinged with corresponding fixture block 12 and pushing ring 8 by movable axis 14 respectively.
During installation, first this device is put in the pit shaft 5 of returnairshaft, then rotational fastener flange 1, the pushing ring 8 of the pit shaft 5 middle and upper part external screw thread 13 along top walks downward, the pushing ring 8 of the bottom external screw thread 13 along bottom is up walked, and then pushing ram 7 merges and is extruded in ring-shaped groove 6 by fixture block 12 and fixes.When, after well shooting, be hit wave action, well lid 10 is upspring, realize resetting fast and accurately after pressure release under the effect jointly of back-moving spring 11 and buffer spring 9, quickly realize effective closure of returnairshaft uphole end 4 simultaneously, thus ensure that ventilation is normal.
This device can automatically reset fast and accurately, can also quickly realize effective closure of returnairshaft uphole end 4 simultaneously, use internally-arranged type structure, simple structure, take up room little, convenient and flexible operation.
The foregoing is only the embodiment that this utility model is the most feasible, not thereby limit to interest field of the present utility model, the equivalence change that all utilization this utility model description and accompanying drawing content thereof are made, within being both contained in interest field of the present utility model.
