Description
Technical field
The present invention relates to the self-reset explosion-proof door for coal mine shaft well head, be specifically related to a kind of vertical shaft self-reset explosion-proof door.
Background technology
The explosion proof door of current China's coal-mine vertical shaft ventilating shaft generally adopts the explosion proof door of normal steel structure, down-hole is once blast, and explosion proof door will be easily damaged, explode from well head, cannot repair use within very short time, cannot recover to ventilate in down-hole, bring potential safety hazard safely to underground ventilating.Thus compromise the life security of personnel in the pit, add the accident rate in colliery.For this reason, colliery more needs the explosion proof door of the safer property of self-resetting type in the safety device of ventilating shaft.
Summary of the invention
The object of this invention is to provide and a kind ofly safer after mine is blasted, automatically can recover ventilation safety in time, ensure the vertical shaft self-reset explosion-proof door of personnel in the pit's safety.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of vertical shaft self-reset explosion-proof door, its feature is: doorframe entirety is divided into four pieces and is assembledly fixed on mine well head, the both sides of doorframe vertically fix two leads respectively, the lower end mounting guiding board of lead, bracing frame is installed in the base plate both sides of doorframe, two leads are respectively by vertical rod, nut and spring composition, spring is set with outside two vertical rods, nut is arranged on top and the spring contact of vertical rod, the column that the lower end of two vertical rods is stretched out with buffing pad two ends is respectively set with, and with nut, doorframe and buffing pad are linked together, buffing pad top is fixed with buffer board, the both sides of buffer board are respectively arranged with multiple buffer stopper, door leaf is positioned at the top of doorframe and is arranged on buffing pad, door leaf adopts two fan door-plates to combine, cushion rubber bumper installed by door leaf, doorframe is installed hinge with in the middle of door leaf and is connected the directive wheel that lead is installed by wire rope, then the assembly pulley by wire rope and bracing frame are installed, counter weight device is connected with hoist.
According to above-mentioned a kind of vertical shaft self-reset explosion-proof door, its feature is: the door leaf told is supported or opposed unlatching simultaneously, automatically can fall reset after unlatching.
The utility model advantage: when gas or coal-dust explosion occur in down-hole, adopt the opposing symmetry of two fan door leafs to open, vertical ventilating shaft explosion-proof door door leaf is subject to blast and is impacted, and opens pressure release, protection blower fan; It is not damaged that buffing pad has pooling feature available protecting door leaf, and the energy-absorbing function of spring makes lead significantly reduce basic role power, thus protection basis is not damaged; After blast, door leaf automatically resets and seals under negative pressure and explosion proof door gravity; When fan trouble blowing-out, door leaf is automatically opened by explosion proof door under the effect of counter weight device, natural ventilation; When blower fan recovers air feed, explosion proof door cuts out sealing again when ventilating shaft negative pressure; When having reversing device for inverted ventilation, the end of door leaf utilizes wire rope to connect hoist, opens and closes freely when enabling mine keep in repair protection simultaneously.

Detailed description of the invention:
A kind of vertical shaft self-reset explosion-proof door, doorframe 1 entirety is divided into four pieces and is assembledly fixed on mine well head, the both sides of doorframe 1 vertically fix two leads 2 respectively, the lower end mounting guiding board 8 of lead 2, bracing frame 10 is installed in the base plate both sides of doorframe 1, two leads 2 are respectively by vertical rod, nut and spring composition, spring is set with outside two vertical rods, nut is arranged on top and the spring contact of vertical rod, the column that the lower end of two vertical rods is stretched out with buffing pad 3 two ends is respectively set with, and with nut, doorframe and buffing pad 3 are linked together, buffing pad 3 top is fixed with buffer board, the both sides of buffer board are respectively arranged with multiple buffer stopper, door leaf 4 is positioned at the top of doorframe 1 and is arranged on buffing pad 3, door leaf 4 adopts two fan door-plates to combine, cushion rubber bumper installed by door leaf 4, doorframe 1 is installed hinge with in the middle of door leaf 4 and is connected the directive wheel 9 that lead 2 is installed by wire rope, then the assembly pulley 5 by wire rope and bracing frame 10 are installed, counter weight device 6 is connected with hoist 7.
In above-described embodiment: the door leaf 4 told is supported or opposed unlatching simultaneously, automatically can fall reset after unlatching.
The utility model beneficial effect: when gas or coal-dust explosion occur in down-hole, the door leaf 4 of vertical ventilating shaft explosion-proof door is subject to blast and is impacted, and opens pressure release, protection blower fan; It is not damaged that buffing pad 3 has pooling feature available protecting door leaf 4, and the energy-absorbing function of spring makes lead 2 pairs of basic role power significantly reduce, thus protection basis is not damaged; After blast, door leaf 4 automatically resets and seals under negative pressure and explosion proof door gravity; When fan trouble blowing-out, door leaf is automatically opened by explosion proof door under the effect of counter weight device 6, natural ventilation; When blower fan recovers air feed, explosion proof door cuts out sealing again when ventilating shaft negative pressure; When having reversing device for inverted ventilation, the end of door leaf 4 utilizes wire rope to connect hoist 7, opens and closes freely when enabling mine keep in repair protection simultaneously.
Embodiment recited above is only be described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; under the prerequisite not departing from design concept of the present invention; the various modification that in this area, common engineers and technicians make technical scheme of the present invention and improvement, all should fall into protection scope of the present invention.
