Description
Technical field
The utility model relates to safety of coal mines equipment, specifically is a kind of tight anti-explosion door, is a kind of observable tight anti-explosion door, mainly is applicable to urgent danger prevention chamber and survival capsule under the mine.
Background technology
For further containing the situation that the particularly serious accident pilosity of China's coal-mine takes place frequently; Strengthen the enterprise security production work, improve the enterprise security level of production, on February 19th, 2011; State Council has issued " State Council is about the notice of further reinforcement enterprise security production work " (No. (2010) 23, promulgated by the State Council) file; Explicitly call for that " force to carry out urgent danger prevention system, monitoring and controlling system, personnel in the pit's navigation system, compressed air self-help system, the technical equipments such as system and channel of communication of suing and labouring that supply water, the structure of urgent danger prevention system under the coal mine needs to improve mine safety protection and emergency management and rescue level; protection miner's life security is a final goal; through analyzing the inherently safe working condition, to refuge chamber setting and technical requirements, builds the underground emergency avoiding system of the full mine of covering in conjunction with national Coal Mine Safety Supervision Bureau.
The underground emergency avoiding system is a core with the down-hole refuge chamber, makes up through effective butt joint the with systems such as the original pressure wind of mine, power supply and information processings, and adapts with the mine production environment.The fire-proof and explosion-proof system of refuge chamber comprises fire prevention tight anti-explosion door and fire-proof and explosion-proof fire dam, is separately positioned on the both sides of refuge chamber, and the airtight buffer system in the refuge chamber comprises outer tight anti-explosion door, wall; Two road sealed doors in the cushion space; Airtight cushion coat around the refuge chamber.This system can prevent the infiltration of toxic gas, alleviates the ore deposit and presses and the destruction of adopting on every side chamber overall structure and supporting, forms an airtight living space.
Refuge chamber is that object of construction production is built in national up-to-date ore deposit, and its corollary equipment all must satisfy national temporary provisions requirement, and explosion proof door also belongs to one of them.There is following shortcoming in general explosion proof door: under special environment condition, can not effectively intercept the intrusion of toxic and harmful and water body especially, satisfy not the existence requirement of urgent danger prevention system; In addition, when blast in the down-hole, shock wave is excessive, and the resistivity of general explosion proof door does not reach, and exists greatly dangerous.The existence of the problems referred to above can not be satisfied the national regulation requirement of refuge chamber, and security presence very big hidden danger.
Summary of the invention
In order to overcome the shortcoming that general explosion proof door does not satisfy the national regulation requirement, the utility model provides a kind of sealing explosion proof door, satisfies the basic function of explosion proof door fully, and meets in the interim provision of down-hole refuge chamber country the requirement to explosion proof door.
The utility model is realized with following technical scheme: a kind of tight anti-explosion door; Comprise doorframe and be installed in the door-plate on the doorframe; Front at door-plate is provided with handle, is provided with on the corresponding doorframe of the interlock that is connected with handle and interlock at the back side of door-plate and is provided with lockhole; The back side of door-plate is provided with reinforcing rib, and door-plate is provided with observation port; Inward flange along doorframe is provided with groove, is provided with weather strip in the groove.
The beneficial effect of the utility model is: flexible, quick, manual, rational in infrastructure, dependable performance have rotproofness.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is a door-plate structure sketch map;
Fig. 3 is the sash structure sketch map;
Fig. 4 is the right view of Fig. 1.
Among the figure: 1, doorframe, 11, groove, 2, door-plate, 3, observation port, 4, handle, 5, weather strip, 6, lockhole, 7, interlock, 8, reinforcing rib.
The specific embodiment
Shown in Fig. 1～4, tight anti-explosion Men Youyi doorframe 1 be installed in the door-plate 2 on the doorframe 1, be provided with handle 4 in the front of door-plate 2, be provided with on the corresponding doorframe 1 of the interlock 7 that is connected with handle 4 and interlock 7 at the back side of door-plate 2 and be provided with lockhole 6; The inside of door-plate 2 is provided with reinforcing rib 8, and door-plate 2 is provided with observation port 3; Inward flange along doorframe 1 is provided with groove 11, is provided with weather strip 5 in the groove 11.
With fixedly reinforcing bar is fastening, door-plate 2 links to each other with doorframe through hinge through the angle melon for doorframe 1, and door-plate 2 can a left side leaves or open on the right side, with integral body of blast wall formation.It is material that door-plate 2 adopts the Q235 shaped steel, along door-plate 2 intersection is provided with two crossed reinforced muscle 8, make door-plate 2 that enough renitency deformation ability arranged.Described interlock 7 adopts has the inside and outside connecting rod locking device that opens and closes function, can realize inside and outside switching.
In order effectively to intercept the intrusion of toxic and harmful and water, play good seal; Described weather strip 5 adopts high temperature resistant, anti abrasive high-strength rubber weather strip.Adopt the high-strength rubber weather strip to seal, the sealing face width, decrement is big, can effectively seal not leak out.The high-strength rubber weather strip forms joint ring, when door-plate cuts out, plays certain cushioning effect, and can reach complete air-tight state, and under suction function, can guarantee that still sealing rubber strip is close to door-plate, makes the sealing of explosion proof door unaffected.When weather strip 5 wearing and tearing, when other damages perhaps occurring, can change at any time, thus the sealing of recovery tight anti-explosion door.
When refuge chamber normally moved, the tight anti-explosion door was in the state of often opening, and when under coal mine, having an accident, the personnel that take refuge get into chamber rapidly; According to switch hand designations on the tight anti-explosion door, move handle 4, start interlock; Close explosion proof door, the dead bolt of interlock is embedded in the lockhole 6 on the doorframe fully, guarantee air-tight state; Thereby the infiltration of blocking-up toxic and harmful and water makes refuge chamber be in confined space, to the personnel of taking refuge a living environment that is isolated from the outside is provided.If blast in the down-hole, it can resist the shock wave of 0.3MPa and 1000 ℃ moment high temperature at least, under 260 ℃ continuous high temperature, can support 12 hours, satisfies national temporary provisions requirement fully.This door is that interlocked control is formed, and when latch shaft arrived certain position, the magnet on the connecting rod was adsorbable; Get into self-closing state; The personnel that take refuge still can accomplish to come in and go out at any time inside and outside the chamber in chamber external opening explosion proof door gets into chamber, have avoided temporal delay.The observation port 3 of explosion proof door is to chamber internal and external environment condition situation and dispose, and through encapsulation process, accomplishes the sealing effectiveness good state, and its effect reduced the hedging time that gets into chamber, for miner's life security has increased a guarantee again.
