Abstract
A multi-functional protection air-tight door used for a coal mine is composed of a door frame and a door body, wherein the main body of the door body is formed in a compression molding mode by a high-strength steel structure, cross tie bars are arranged in the door body, locking point shafts are arranged on four edges of the door body, a plurality of connecting rods are arranged in the door body, a sealing groove is formed in the periphery of the interior of the door body, a fire-proof sealing ring is arranged in the sealing groove, the whole surface of the interior of the door body is coated with fire-proof heat insulation coating material, and a plurality of oblique iron blocks corresponding to locking points in position are arranged on the inner side of the door frame on the door body. The multi-functional protection air-tight door used for the coal mine is characterized in that the door body is enabled to have explosion resistant performance and be corrosion resisting, capable of avoiding generation of friction sparks, high in strength and strong in impact energy absorption performance under a warm environment; and the door body is locked and sealed through multiple locking points, the fire-proof function and air tight performance can still be achieved under the situation that a single locking point is invalid, and especially when a fire disaster caused by gas and coal-dust explosion occurs, the fire-proof sealing ring is not burnt in the fire disaster and is stronger in sealing performance as temperature becomes higher, and therefore a protection and airtight function is achieved in a shelter or other special occasions, and safety of miners can be effectively guaranteed.
Description
Affiliated technical field
The utility model belongs to coal mine refuge chamber, be a kind ofly also can be used on the survival capsule, powder magazine, civil air defense constructions and installations, naval vessel hatch door, chemical plant, the extraordinary places such as factory building isolation fire prevention.
Background technology
At present; domestic airtight blast door is multiplex in underground refuge chamber and survival capsule; when gas occurs in the down-hole; the burst accidents such as coal-dust explosion, fire, floods and roof fall; during in danger can't in time withdrawing; the survival personnel will enter the shelter by airtight blast door, and then ensure that outside adverse circumstances can not encroach on the protected personnel.Existing airtight blast door all adopts single steel work, the deficiency that it exists is not have isolation layer, sealing ring all adopts combustible material, weight is large, transportation is installed inconvenient, and cost is higher, although can resist blast impulse, if but gas and dust explosion causes fire, sealing ring does not have fire-proof function.Therefore when fire, miner's safety can not get ensureing.
Summary of the invention
In order to overcome the problem of above-mentioned existence, the utility model purpose is that a kind of colliery multifunctional protection sealed door will be provided.The door body adopts high-quality steel body, welding well word lacing wire in the door body, and the ability that has increased door body opposing blast impulse has alleviated again weight, and door body inside scribbles special coating, can strengthen fire prevention, heat insulation, corrosion resistance.Composite material in the outside covering of coating improves heat-proof quality again, again can be antistatic.
The technical scheme that its technical problem that solves the utility model adopts is to comprise doorframe and door body, the compression molding of door phosphor bodies employing high strength steel structure, be provided with the lacing wire of welding well word in the door body, the place, four limits of door body is provided with welding lock point axle, is provided with master connecting-rod A in the door body, slave connecting rod B, slave connecting rod C, slave connecting rod D, master connecting-rod E, slave connecting rod F, slave connecting rod G, slave connecting rod H, be provided with seal groove around in the door body, be provided with the fire proof seal circle in the seal groove, the whole face in the door body scribbles fire-proof and thermal-insulation coating, fire-proof and thermal-insulation coating is provided with composite coating, doorframe is inboard to be provided with wedge A, wedge B, wedge C with lock point correspondence position, wedge D, wedge E, wedge F, wedge G, wedge H, wedge I, wedge J, wedge K, wedge L, be provided with the steel plate of welding in the doorframe outermost, the steel plate place is provided with the channel-section steel of welding, by channel-section steel with door frame welding in the steel concrete in the places such as refuge chamber.Like this, the effect of protection airtight can be reached, miner's safety can be guaranteed again.Particularly when breaking out of fire, can play the effect of protection airtight.
The beneficial effects of the utility model are, adopt the high strength steel structure, the lacing wire of interior welds well word, the door body scribbles fire-proof and thermal-insulation coating and composite material, greatly alleviated the weight of door body, have under thermal environment, have corrosion-resistant, avoid the performance that friction spark and intensity are high, apparatus with shock absorbing is strong, play the effect of protection airtight under shelter or other special occasions.Because whole airtight blast door has up to 12 lock points, so even there is single lock point to fail to lock, all the other lock points still can play a role, and make airtight blast door reach airtight effect, have improved security performance.
