Description
Technical field
The present invention relates to the coalmine ventilation safety device, the buffering explosion proof door that particularly a kind of coal mine shaft, door leaf can rise with buffing pad.
Background technology
The explosion proof door of ventilating shaft is the explosion proof door of general common door form steel work in the existing coalmine ventilation safety device; In a single day run into the situation that well shooting takes place in the colliery; Explosion proof door very easily is destroyed or flies away from well head, and explosion proof door can't reset at short notice, will cause like this and can't recover within a short period of time under the coal mine to ventilate; Thereby can't exhale pernicious gases; Let the personnel of speedily carrying out rescue work lose and speedily carry out rescue work the relief time, also seriously jeopardized staff's life security under the coal mine simultaneously, cause the disaster after accident takes place to enlarge.For this reason, the colliery presses for the explosion proof door that has more safety that can in time reset that research and development are used for the coalmine ventilation well.
Summary of the invention
The objective of the invention is to overcome the prior art shortcoming; Provide vertical shaft to rise buffering from the horizontal reset explosion proof door, when in a single day the existing coal mine air-shaft of solution blasted, explosion proof door very easily was destroyed and can not in time resets; Ventilate thereby can not reply the down-hole as early as possible, have the problem of potential safety hazard.
The present invention realizes through following technical scheme:
Vertical shaft rises buffering from the horizontal reset explosion proof door, and comprising: be fixed on the doorframe on the well head, by the door leaf that two door-plates are formed, two said door-plates are walked around assembly pulley through wire rope respectively and are connected with counterweight, and two said counterweights are positioned at the top of position-limit mechanism; It is characterized in that: vertically fixing respectively two leads in the both sides of said doorframe; Two said leads are made up of vertical rod, nut and spring respectively; Two said vertical rods are set with said spring outward; The top that said nut is installed in said vertical rod contacts with said spring; The column suit that stretch out with the buffing pad two ends respectively the lower end of two said vertical rods, and with nut said doorframe and said buffing pad are linked together, said door leaf is positioned at the top of said doorframe and is installed on the said buffing pad; Said buffing pad top is fixed with buffer board, and the both sides of said buffer board are respectively arranged with a plurality of buffer stoppers.
Said two said door-plates are hinged on the described buffing pad through hinge respectively.
The bottom of said buffing pad is provided with crossbeam, and said crossbeam is a tapered beam, the cross section of said tapered beam or be del, or for trapezoidal, or be streamlined, or be arbitrary shape wide at the top and narrow at the bottom.
Described buffer stopper or make with elastomeric material, or make with plastic material.
Described position-limit mechanism is a fixed support.
The following beneficial effect that the present invention compared with prior art has.
1, the present invention buffering vertical shaft explosion proof door both sides of rising are equipped with lead, and impact generated by explosion ripple or high pressure draught make buffing pad and are attached thereto the door leaf that connects and rise along lead, realize pressure release; Through spring buffer with overcome gravity work production and realize buffering.
2, the present invention rises and buffer stopper is installed on the buffer board in the buffering vertical shaft explosion proof door, and when two door leafs bumped against with buffer board, the buffer stopper on the buffer board absorbed energy, and the counteracting impact force plays the effect of buffering.
3, the rise buffing pad bottom of buffering vertical shaft explosion proof door of the present invention is equipped with tapered beam, has disperseed the active force of shock wave or high pressure draught, has reduced beam action power.
4, the present invention's buffering vertical shaft explosion proof door that rises adopts counterweight, and when main air blower was not worked, counterweight is opened door leaf made the mine can natural ventilation, and when door leaf was opened about 45 °, position-limit mechanism limited counterweight, and counterweight is not descended continuing; When main air blower was resumed work, door leaf was by the automatic adhesive of negative pressure.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Below in conjunction with accompanying drawing the present invention's buffering vertical shaft explosion proof door that rises is further described.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; Vertical shaft rises buffering from the horizontal reset explosion proof door; Comprise: be fixed on the doorframe 1 on the well head; 2, two said door-plates 8 of door leaf of being made up of two door-plates 8 are walked around assembly pulley through wire rope respectively and are connected with counterweight 12, and two said counterweights 12 are positioned at the top of position-limit mechanism 13; Vertically fixing respectively two leads 4 in the both sides of said doorframe 1; Two said leads 4 are made up of vertical rod 5, nut 6 and spring 7 respectively; Be set with said spring 7 outside two said vertical rods 5; The top that said nut 6 is installed in said vertical rod 5 contacts with said spring 7; The column suit that stretch out with buffing pad 3 two ends respectively the lower end of two said vertical rods 5, and with nut said doorframe 1 is linked together with said buffing pad 3, said door leaf 2 is positioned at the top of said doorframe 1 and is installed on the said buffing pad 3; Said buffing pad 3 tops are fixed with buffer board 9, and the both sides of said buffer board 9 are respectively arranged with a plurality of buffer stoppers 10.
Said two said door-plates 8 are hinged on the described buffing pad 3 through hinge respectively.
The bottom of said buffing pad 3 is provided with crossbeam 11, and said crossbeam 11 is a tapered beam, the cross section of said tapered beam or be del, or for trapezoidal, or be streamlined, or be arbitrary shape wide at the top and narrow at the bottom.
Described buffer stopper 10 or make with elastomeric material, or make with plastic material.
Described position-limit mechanism 13 is a fixed support, and the limited mechanism of counterweight 12 13 is spacing.
Rise two door-plates 8 of buffering vertical shaft explosion proof door of the present invention are opened revolution by impact generated by explosion ripple or high pressure draught and are impinged upon on the buffer board 9 on the buffing pad 3; Rely on the buffer stopper 10 on the buffer board 9 to absorb energy; Offset impact force; Simultaneously, two door-plates 8 all impinge upon on the buffer board 9, make buffing pad 3 and buffer board 9 stress equalizations.Buffing pad 3 usefulness leads 4 are connected on the doorframe 1; Doorframe 1 is fixed, and impact generated by explosion ripple or high pressure draught make buffing pad 3 and are attached thereto the door leaf 2, the buffer board 9 that connect and rise along lead 4, realize pressure release; Through the cushioning effect and the gravity work production own of spring 7, realize buffering; Wedge shape crossbeam 11 on the buffing pad 3 can disperse the active force of shock wave or high pressure draught in addition, reduces the active force to crossbeam 11.The conical surface is adopted on the corrugated of meeting of door leaf 2; Reliable in structure, in light weight, can slacken shock wave or high pressure draught destruction to door leaf 2; Door leaf 2 leans on negative pressure to reset fully after resetting to certain angle under the deadweight effect after the pressure release; Again well head is formed sealing, ventilate, protection underground work personnel's life security thereby recover the down-hole.
