Description
Technical field
The utility model especially relates to a kind of underground emergency avoiding system airtight blast door.
Background technology
Under coal mine, airtight blast door adopts water dam and civil air defense constructions and installations gate more at present, only has a small amount of enterprise to develop and is specifically designed to the special protection sealed door of mine urgent danger prevention system, but have following defect.
(1) sealing effectiveness is bad.Because door leaf neighboring only arranges 1 circle weather strip, and weather strip do not adopt fire-retardant sealing ring fire-retardant, antistatic, high temperature resistant, oil resisting material, and in use sealing ring is easy
Because high temperature or for a long time need not and damage, cause the sealing effectiveness of whole airtight blast door bad, can not provide a relative closure and safe environment for the facility inside of taking refuge.
(2) under high temperature, effect of heat insulation is bad.What in door leaf, fill is heat insulation foam, this kind of multipotency of material bears the temperature of 700 DEG C, if there is gas explosion below mine, temperature now just can not be below 700 DEG C, once exceed this temperature, heat insulation foam will damage, and therefore high heat will import in refuge chamber like this, the ecological deterioration that causes taking refuge in facility.
(3) overall explosion-proof impact capacity is not strong.Owing to only the wedge being driven by linkage being set in door leaf both sides, door leaf is locked, in the time that whole door leaf is subject to blast impulse, because upper and lower both sides do not arrange the wedge being driven by linkage, the both sides up and down of door leaf are easily out of shape, door leaf after distortion there will be poorly sealed problem, the situation such as leak air, leak, causes the relatively airtight and safe environment in chamber inside destroyed.
(4) complex operation, unlatching and locking used time are longer, expend muscle power, can't reach the object of locking.
Utility model content

detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
embodiment 1
A kind of underground emergency avoiding system airtight blast door, comprises door-plate 1, doorframe 2, retaining mechanism 3, square steel reinforcing rib 4, angle steel 5, hinge 6, short connecting rod 7, long connecting rod 8, wedge shape position-limit mechanism 9, bearing 10, gear wheel 11, pinion 12, runner 13, observation port 14 and hanger 15, door-plate 1 connects doorframe 2, retaining mechanism 3 connects runner 13, square steel reinforcing rib 4 connecting angles 5, hinge 6 connects short connecting rod 7, and short connecting rod 7 connects long connecting rod 8, and wedge shape position-limit mechanism 9 connects long connecting rod 8, bearing 10 connects wedge shape position-limit mechanism 9, gear wheel 11 connects pinion 12, and pinion 12 connects runner 13, and observation port 14 connects door-plate 1, hanger 15 connects doorframe 2, described door-plate adopts sunken inside deep trouth technology, and contact surface adopts double sealing, and adopts tensioning technique, described wedge shape position-limit mechanism is interrelated by bearing and door-plate, spring supporting is arranged at bearing bottom, plays damping effect, between described square steel reinforcing rib, is filled with heat-barrier material, isolated outside high temperature, heat-barrier material is aerogel heat-insulating felt.
Door body adopts the outside opening ways of single fan, defeats tight fire-retardant sealed ring deformation by the locking-adjustable of retaining mechanism, makes to have accomplished to coordinate to greatest extent between door-plate and doorframe, ensures the seal of door-plate; Fire-retardant sealing ring is housed in deep trouth; this fire-retardant sealing ring is made up of fluorine glue material fire-retardant, antistatic, high temperature resistant, oil resistant; to provide doorframe bossing to go deep in door-plate; compress door-plate; and stop entering of gas and liquid; ensure to occur in any case in colliery, can both reach good sealing effectiveness; , encapsulant is in the situation of closing the door, and protection, in seal groove, has been played the sealing effect of the facility of taking refuge.Door-plate inner side is welded with reinforcing rib, the ability that can strengthen door-plate and bear larger blast impulse; Between reinforcing rib, be filled with heat-barrier material, isolated outside high temperature, material is aerogel heat-insulating felt, and aeroge typically refers to nanometer scale ultramicro powder mutually to be assembled and form nanoporous network structure, and in network hole, is full of the lightweight nano solid material of gaseous state decentralized medium.This new material seems fragile can't bear, in fact very sturdy and durable, and high energy bears the high temperature of 1400 DEG C, and material is lighter, is called as the lightest solid, can not add the total quality of gate body.Door-plate is provided with observation port, is made up of high-strength armoured-glass, can keep out the shock wave of some strength, has ensured to link up with the external world; Doorframe is formed by i iron and the square steel assembly welding of 10 mm, and surrounding is respectively equipped with outward extending square steel fixed mount, is deep into and takes refuge in facility blast wall, plays fixation.Doorframe upside is welded with hanger, is convenient to carrying and lifting.On doorframe panel, be welded with bearing, door one side upper, middle and lower is equipped with hinge, and door leaf is connected with doorframe.
Door when locking, applies clockwise moment to handwheel, and hand wheel rotating drives pinion rotation, is mediated moment is passed to and on gear wheel, drives its rotation, gear wheel to drive fixed thereon 2 again by gear
Individual short connecting rod plane motion, short connecting rod drives long connecting rod and wedge shape position-limit mechanism to rotate on fixed axis separately, forms 8 link gears of connecting rod more than, realizes and opens and closes function.When door is opened, principle is identical, and moment is contrary.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
