Description
Technical field
The utility model relates to a kind of safety protection equipment, relates in particular to a kind of mine refuge chamber blast-resistant door.
Background technology
The safety of mining in the industry is the matter of utmost importance of mining industry, in order to let the miner can be more safe when having an accident, can be provided with refuge chamber usually in the mine; And what be even more important in the refuge chamber is exactly blast-resistant door, and it not only will possess good airproof performance, good thermal insulation; Processing ease fast also will bear high-intensity blast impulse power; Traditional blast-resistant door normally leans on the door leaf ripple that directly withstands shocks, because door leaf is a plane, explosion wave has sizable impact force action in its geometric center position behind the contact door leaf; To produce big moment for the blast-resistant door locking device like this, cause damage easily.
The utility model content
The purpose of the utility model is to provide a kind of mine refuge chamber blast-resistant door, has to disperse shock wave to improve the effect of blast-resistant door impact resistance.
The purpose of the utility model is to realize through following technical scheme:
A kind of mine refuge chamber blast-resistant door comprises doorframe, door leaf, one side being connected through the hinge on doorframe of said door leaf; Said door leaf central vertical is provided with leading screw; Said leading screw two ends are equipped with handwheel, are provided with adpting flange between said handwheel and the door leaf; Be hinged with connecting rod on the said adpting flange; The said connecting rod other end is fixed on the door leaf through the connecting rod lasso; Said door leaf top is provided with explosion-proof form, and the non-side that adpting flange is installed is provided with the arc flow distribution plate between said handwheel and the door leaf.
Said door leaf is provided with reinforcing rib; Said reinforcing rib and door leaf are filled with the thermal insulation material in the inner gap that forms; Said thermal insulation material outer setting has the thermal insulation cover plate.
The said door leaf position that contacts with doorframe is provided with weather strip; Said leading screw is provided with sealing ring.
The beneficial effect of the utility model is: door leaf is provided with the arc flow distribution plate, to reach the effect of shunting explosion wave, has also improved the impact resistance of mine refuge chamber blast-resistant door self when having reduced external shock power; Door leaf is provided with the thermal insulation layer can play good effect of heat insulation, adopts each connecting rod of handwheel control to move simultaneously, and handwheel in the middle of opening, only need operating when locking door is easy to operate, saves escape time; Door-plate and doorframe contact portion are provided with encapsulant, and sealing ring and tetrafluoro filler are installed on the leading screw, can be good at guaranteeing the tightness requirement of mine refuge chamber blast-resistant door; Door leaf top is provided with the convenient external circumstances of observing of observation port.
