Abstract
The utility model discloses a novel explosion -proof well lid, including to be equipped with the wall of a well of wind cave, and installing the well lid in well head department, and evenly arrange three spinal branch framves in well head department, and weld the circular roof at three spinal branchs frame top, the roof links to each other through the welding with the support, and the spring is still installed to the roof lower part and huge impact is convenient for absorb by flexible material, and there is the track groove support the higher authority, and the gyro wheel on the well lid can make the well lid reciprocate along the track groove on the support, explosion -proof well lid adopts the pathway movement structure and the toper structural design of well lid bottom, makes can be fast accurate the reseing of well lid, adopts spring and flexible material can adsorb huge surge pressure and prevents that the well lid from being blown up, the toper structural design of well lid lower part and the sealed effect that the rubber belt around the toper structure can improve the well lid.
Description
Technical field
This utility model relates to a kind of Antiexplosive manhole cover, a kind of anti-new type explosion proof well lid blowing up also energy parking position accuracy.
Background technology
nullThe Antiexplosive manhole cover being currently known is mounted in and is provided with at the exhaust outlet of chief ventilators，When normal ventilation, he is used to isolate that down-hole is distinguished and admirable and surface air，Prevent Air escape branch，Ensure that ventilating system is normal，When down-hole once occurs gas or dust explosion accident，The impact air-flow that Antiexplosive manhole cover is exploded is opened，Thus，Air blast is directly discharged in surface air，Play the effect of pressure release，Prevent chief ventilators from causing damage because of air blast impact，But current Antiexplosive manhole cover there is also certain problem，When there is huge gas or coal-dust explosion in down-hole，Antiexplosive manhole cover can be blown up by powerful shock wave，Being allowed to can not normal reset，There is serious potential safety hazard，And the mode sealing many employing sealing fluid sealings of current Antiexplosive manhole cover，And most of sealing fluid many uses water-stop，The water capacity is easily evaporated，Need constantly to supplement，It is also easy to cause the waste of water resource，Additionally ventilation blower manager affects tours of inspection and the machine operation inspection of ventilation blower due to the situation often observing sealing fluid.
Utility model content
(1) to solve the technical problem that
For solve the problems referred to above, the utility model proposes a kind of can effectively pressure release prevent well lid from being blown up, can parking position accuracy and need not sealing fluid sealing new type explosion proof well lid.
(2) technical scheme
New type explosion proof well lid of the present utility model, including the borehole wall being provided with wind cave, and it is arranged on the well lid at well head, and it is evenly arranged in three supports at well head, and it being welded on the circular top plate of three cradle top, top board and support by being weldingly connected, top board bottom is also equipped with spring and flexible material is easy to absorb huge impact, there is rail groove support top, and the roller on well lid can make well lid move up and down along the rail groove on support.
Further, well lid bottom is pyramidal structure, and surrounding has balata belt to be fixed on well lid by riveting, is the most not only beneficial to well lid quick and precisely resetting after leaving well head and also helps the sealing to well head.
Further, described top board is circular configuration.
(3) beneficial effect
This utility model is compared with prior art, it has the advantages that Antiexplosive manhole cover of the present utility model is placed on support in specific track by roller, make well lid when suffering powerful impact, well lid can be made to move in track, and the top board due to frame upper, the spring of top board bottom and the common effect of flexible material, huge surge can be absorbed, mitigation impact on top board, prevent top board and well lid from being blown up, simultaneously, due to support and the design of well lid lower end pyramidal structure, well lid can be made quick and precisely to reset, the balata belt of well lid lower end taper structure design and surrounding can be effectively improved the sealing of well lid, not only economy but also easily realize.

Detailed description of the invention
A kind of new type explosion proof well lid as shown in Figure 1 to Figure 2, including the borehole wall 2 being provided with wind cave 1, and it is arranged on the well lid 3 at well head, and it is evenly arranged in three supports 7 at well head, and it is welded on the circular top plate 6 at three support 7 tops, top board 6 and support 7 are by being weldingly connected, and top board 6 bottom is also equipped with spring 5 and flexible material 4 is easy to absorb huge impact.There is rail groove 8 support 7 top, three rollers 9 it are evenly equipped with on well lid, roller 9 can make well lid 3 move up and down along the rail groove 8 on support 7, well lid 3 bottom is pyramidal structure, and surrounding has balata belt 2 to be fixed on well lid 3 by riveting, the most not only it is beneficial to well lid 3 quick and precisely resetting after leaving well head and also helps the sealing to well head.When well lid 3 suffers huge impact, the roller 9 on well lid 3 rail groove 8 on support 7 moves up, well lid 3 top acts on flexible material 4 and spring 5, flexible material 4 and spring 5 can absorb huge kinetic energy, it is substantially reduced the impact kinetic energy impact failure to top board 6, prevents well lid 3 from de-orbiting and flying out.
New type explosion proof well lid of the present utility model, has an advantage in that: 1. Antiexplosive manhole cover uses the taper structure design bottom track structure and well lid, enables well lid to reset fast and accurately；2. use spring and flexible material can adsorb enormous impact pressure and prevent well lid from being blown up.3. the conical design of well lid bottom and the balata belt of pyramidal structure surrounding can improve the sealing effectiveness of well lid.
Embodiment described above is only to be described preferred implementation of the present utility model, is not defined spirit and scope of the present utility model.On the premise of relating to without departing from this utility model and conceive; various deformation that the technical solution of the utility model is made by this area ordinary person and improvement; protection domain of the present utility model all should be dropped into; the technology contents that this utility model is claimed, all records in detail in the claims.
