Abstract
The utility model discloses an explosion-proof well cover device. The explosion-proof well cover device comprises a well hole supported by concrete, wherein a well cover is covered on the well hole; reinforced concrete blocks are arranged on the periphery of the well cover; the well cover consists of four isosceles triangular plate bodies; a fixing piece is arranged on each plate body; a threaded pole is arranged on the fixing piece; the threaded pole penetrates through the reinforced concrete block to expose from the reinforced concrete block; and a crank is arranged on the threaded pole which is exposed from the reinforced concrete block. According to the explosion-proof well cover device, a concrete and well cover integrated structure is adopted, so that the firm degree of the well cover is increased; moreover, the well cover consists of four isosceles triangular plate bodies, so when violent explosion happens, the airflow in a well can thrust the well cover aside, and can be released; the well cover forms buffering, so that the destructiveness of impact airflow is reduced; and moreover, the well cover can be reused and the use cost is reduced.
Description
Technical field
The utility model relates to a kind of explosion-proof manhole lid device.
Background technology
At present, the following well in mining area uses common walling crib to cooperate with the simple of well lid always, and its sealing is relatively poor; Perhaps use article such as asbestos cloth, sandy soil to carry out capping; Its intensity difference, and down-hole situation such as blast is easily well lid to be blown up; Need change well lid again, increase use cost.This shows that prior art needs further improvement and develops.
The utility model content
The utility model provides a kind of explosion-proof manhole lid device for solving above-mentioned defective of the prior art, to improve the intensity of well lid, reduces it and damages probability.
For solving the problems of the technologies described above, the utility model scheme comprises:
A kind of explosion-proof manhole lid device, it comprises the pit shaft that is supported by concrete, is coated with well lid on this pit shaft; Wherein, be provided with the reinforced concrete piece around this well lid, well lid is made up of the plate body of four isosceles triangles; Be provided with a fixture on each plate body; Fixture is provided with a screw thread stock, and the screw thread stock passes reinforced concrete piece dew and puts in the reinforced concrete piece outside, reveals the screw thread stock of putting the reinforced concrete piece outside and is provided with crank.
Described explosion-proof manhole lid device, wherein, the top of above-mentioned well lid is provided with a well lid bracing frame, is provided with damping device between well lid and the reinforced concrete piece.
A kind of explosion-proof manhole lid device that the utility model provides adopts concrete and well lid integral structure, has increased the firm degree of well lid; And well lid is made up of the plate body of four isosceles triangles, and the air-flow when heavy explosion takes place in the well can be washed well lid open, discharges; Well lid forms buffering; Reduced the destructiveness of impact air-flow, and well lid can reuse, reduce use cost.
Description of drawings
Fig. 1 is the structural representation sketch of explosion-proof manhole lid device in the utility model.
The specific embodiment
The utility model provides a kind of explosion-proof manhole lid device; As shown in Figure 1, it comprises the pit shaft 1 that is supported by concrete, is coated with well lid 2 on this pit shaft 1; Be provided with reinforced concrete piece 3 around this well lid 2; Well lid 2 is made up of the plate body of four isosceles triangles, is provided with a fixture 4 on each plate body, and fixture 4 is provided with a screw thread stock 5; Screw thread stock 5 passes reinforced concrete piece 3 dew and puts in reinforced concrete piece 3 outsides, reveals the screw thread stock 5 of putting reinforced concrete piece 3 outsides and is provided with crank 6.And the top of well lid 2 is provided with a well lid bracing frame 7, is provided with damping device 8 between well lid 2 and the reinforced concrete piece 3, has strengthened its firmness.
