The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
As shown in Figure 1, horizontal well and inclined shaft comprise doorframe 1, door leaf 2 from the horizontal reset explosion proof door, hinge 3 and be contained in door leaf and doorframe on door lock 4; The structure of described doorframe 1 is made up of three door pillars in left, center, right and upper and lower door beam for falling " day " shape; The voluntarily resetting-mechanism of described hinge 3 for being provided with, doorframe is provided with two door leafs 2; Its two fan door 2 is installed on the middle door pillar of doorframe 1 through resetting-mechanism voluntarily respectively, also two fan doors 2 can be installed on the left and right door pillar of doorframe 1 through resetting-mechanism voluntarily respectively.On two fan doors 2, respectively connect a counter weight device 5.
Resetting-mechanism has following several embodiment voluntarily:
As shown in Figure 2, horizontal well and inclined shaft are the inclined-plane detachable hinges from the resetting-mechanism voluntarily of horizontal reset explosion proof door.It comprises Fixed hinge 3-1, movable hinge 3-2 and be contained in Fixed hinge and movable hinge in movable axis 3-3; On the hinge contact end face of movable hinge and Fixed hinge, be provided with spiral inclination fitting face 3-4; On the middle door pillar of described Fixed hinge 3-1 fixed installation doorframe 1, described movable hinge 3-2 is fixedly mounted on the door leaf 2.On each door leaf 2 at least two hinges are housed, wherein: one is the inclined-plane detachable hinge in the present embodiment, and another is a ready-made hinge.
As shown in Figure 3, horizontal well and inclined shaft are the inclined-plane detachable hinges of band ball from the resetting-mechanism voluntarily of horizontal reset explosion proof door.It comprises Fixed hinge 3-1, movable hinge 3-2 and be contained in Fixed hinge and movable hinge in movable axis 3-3; On the hinge contact end face of movable hinge and Fixed hinge, be provided with spiral inclination fitting face 3-4; Several balls 3-5 also is housed between spiral inclination fitting face 3-4, and ball has wherein reduced between the spiral inclination fitting face and has rubbed, and makes door leaf more flexible and reliable from horizontal reset.On the middle door pillar of described Fixed hinge 3-1 fixed installation doorframe 1, described movable hinge 3-2 is fixedly mounted on the door leaf 2.On each door leaf 2 at least two hinges are housed, wherein: one is the inclined-plane detachable hinge in the present embodiment, and another is a ready-made hinge.
More than the explosion proof door course of work of two kinds of embodiment be:
Under coal mine, explosion time takes place, two door leafs 2 of explosion proof door are washed open by impact generated by explosion ripple or high pressure draught, and door leaf will be opened two door leafs 2 simultaneously along this spiral inclination fitting face 3-4 rising of resetting-mechanism voluntarily.When impact generated by explosion ripple or high pressure draught in the past after, door leaf 2 under the self gravitation effect, this voluntarily the spiral inclination fitting face 3-4 of resetting-mechanism descend, close voluntarily simultaneously.So just accomplished door leaf 2 from horizontal reset, and again the well head door is closed and is sealed.At this moment main air blower is extracted the pernicious gas of down-hole out, guarantees underground work personnel's safety.
Embodiment 3
As shown in Figure 4, horizontal well and inclined shaft are from the resetting-mechanism voluntarily of horizontal reset explosion proof door, and this is a kind of torsionspring hinge that has.It comprises Fixed hinge 3-1, movable hinge 3-2 and be contained in Fixed hinge and movable hinge in movable axis 3-3; Suit torsionspring 3-6 on movable axis 3-3, two stressed terminations of torsionspring act on respectively on Fixed hinge 3-1 (doorframe) and the movable hinge 3-2 (door leaf).On the middle door pillar of described Fixed hinge 3-1 fixed installation doorframe 1, described movable hinge 3-2 is fixedly mounted on the door leaf 2.On each door leaf 2 at least two hinges are housed.
This torsionspring hinge that has also can adopt the existing ready-made hinge that has torsionspring.When selecting for use, should consider the size of torsionspring restoring force.
The explosion proof door course of work of this kind embodiment is:
Explosion time takes place under coal mine; Two door leafs 2 of explosion proof door are opened by impact generated by explosion ripple or high pressure draught; Make the torsionspring 3-6 distortion and the accumulation of energy of hinge simultaneously; When impact generated by explosion ripple or high pressure draught in the past after, door leaf 2 cuts out under the effect of torsionspring 3-6 restoring force voluntarily.So just accomplished door leaf 2 from horizontal reset, and again the well head door is closed and is sealed.At this moment just can open main air blower work again, the pernicious gas of down-hole is extracted out, guarantee underground work personnel's safety.
