Abstract
The utility model relates to an explosion-proof door with buffer blocks at the back, which provides an active safety facility for a coal mine ventilation system and solves the current serious problems that a coal mine vertical shaft explosion-proof door flies or is broken by strike after underground explosion and cannot be reset in a short period, and the ventilation system is difficult to restore. The explosion-proof door comprises a door frame, a door leaf, a hinge, the buffer blocks and an intermediate door post, wherein the door frame is divided into two parts through the intermediate door post; the plurality of buffer blocks are arranged on the door leaf; and the section of the intermediate door post is wedge-shaped or conversely triangular or conversely trapezoidal. The explosion-proof door disclosed by the utility model has the advantages of being simple in structure, being safe and reliable and is capable of rapidly resetting, rapidly restoring the ventilation system, making the time for emergency and salvation in advance, reducing personal casualty and reducing loss caused by accidents, so that the explosion-proof property and the safety action of the explosion-proof door are greatly increased.
Description
Technical field
The utility model belongs to the explosion proof door technical field,, particularly relate to a kind of explosion proof door that has buffer stopper as the back in the coalmine ventilation safety device ventilating shaft.
Background technology
The explosion proof door of existing coalmine ventilation safety device ventilating shaft, in case run into the situation that well shooting takes place, under shock wave and high pressure draught effect; Explosion proof door is very easily by impact failure or fly away from well head; This moment can't recover in the short time to ventilate in the down-hole, thereby can't discharge methane gas, lets the personnel of speedily carrying out rescue work lose and speedily carries out rescue work relief in the time of the time; Also seriously jeopardize underground work personnel's life security, enlarged the disaster consequence easily.
Summary of the invention
The purpose of the utility model is exactly to overcome the deficiency that prior art exists and the prior art problem of solution, available buffer is provided, effectively improves the explosion proof door that has buffer stopper of safety and reliability.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of back has the explosion proof door of buffer stopper, comprises doorframe 1, door leaf 2 and hinge 3, and door leaf is installed on the doorframe through hinge, it is characterized in that: also comprise buffer stopper 4, and with described doorframe middle door pillar 5 divided into two parts; Some block buffering pieces are set on described door leaf.
The cross section of door pillar 5 is a wedge shape in the middle of described, or is del, or for trapezoidal.
The utility model is compared the beneficial effect that is had with prior art:
1, the buffer stopper through on door leaf, being provided with cushions when explosion proof door bumps, and the destruction to explosion proof door of preventing to explode can be improved safety and reliability, has effectively guaranteed the available ventilation of ventilating shaft.
2, middle door pillar adopts wedge structure can disperse shock wave or high pressure draught, reduces the destructive power of shock wave to middle door pillar.
The utility model can be used for the horizontal well in colliery, also can be used for the vertical shaft in colliery.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional view of the utility model central sill.
Among the figure: doorframe 1, door leaf 2, hinge 3, buffer stopper 4 and middle door pillar 5.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, a kind of explosion proof door that has buffer stopper.It comprises doorframe 1, door leaf 2, hinge 3, buffer stopper 4 and middle door pillar 5, and door leaf is installed on the doorframe through hinge; Middle door pillar 5 is with described doorframe separated into two parts; Some block buffering pieces 4 are set on described door leaf 2.The cross section of door pillar 5 is a wedge shape in the middle of described, or is del, or for trapezoidal.Described buffer stopper 4 usefulness plastic materials are processed.
The course of work of the utility model is:
Under coal mine, explosion time takes place, two door leafs 2 are opened by impact generated by explosion ripple or high pressure draught, and the buffer stopper 4 on two door leafs 2 bumps against, and two door leafs 2 can not be destroyed under the cushioning effect of buffer stopper 4.When shock wave and the high pressure draught of blast in the past after, two door leafs 2 are resetted, just can realize the sealing of well head again, at this moment main air blower is extracted the pernicious gas of down-hole out, assurance underground work personnel's safety.
