Abstract
The utility model discloses a gas-outburst anti-backwind device which comprises an impact wave sensor, a rotary disk, a pull rod, a connecting rod, a small live shaft, a suspension sucking cup, a movable hook, an anti-outburst door, a rotary shaft and a door frame; wherein the movable hook is connected with the suspension sucking cup by the small live shaft, the door frame is mounted on the wall of the drift, the impact wave sensor and the pull rod are mounted on the rotary disk, the pull rod is connected with the movable hook by the connecting rod, the movable hook hooks the left side of the anti-outburst door and the right side of the anti-outburst door is connected with the upper part of the door frame by the rotary shaft. Thereby the structure can limit the gas and the coal from other areas, can prevent the backwind in the ventilation system and the expanding of the accident, and has the advantages of being simple in structure, safe, practical and obvious in the effect, etc.
Description
Technical field:
The utility model relates to the Protrudent set of guarding against contrary wind for gas that uses under a kind of coal mine.
Background technology:
Gas is outstanding to be one of the major casualty factor in colliery, and it is under the unexpected release action of the inner mash gas dynamic in coal seam, coal and gas is gushed out fast caused the accident.Outstanding the mostly occurring of large-scale gas has the driving face of outburst danger, very easily causes whole exploiting field to cause gas explosion against the wind after the generation, and the coal of gushing out stops up and destroys tunnel, the safety that is greatly threatening down-hole miner.According to outstanding crash analysis, inducing when occurring in the coal road driving more than 95% and blowing out is outstanding.When the workman implements the bursting work of coal road driving at present, all be to hide behind the safety area the staff, implement to blow out operating process again, the workman can not initiatively prevent the harm of coal and gas burst accident effectively, in case generation gas burst accident, very easily cause ventilation system contrary wind even gas explosion, enlarge damaging range and involve other area.
The utility model content:
The purpose of this utility model provides a kind of after driving face generation gas is outstanding, can stop outstanding energy unofficial biography, and the gas of avoiding gushing out causes against the wind to other area impact, effectively reduces the Protrudent set of guarding against contrary wind for gas of outstanding accident impact scope.
To achieve these goals, the utility model comprises: shock wave tablet, rolling disc, pull bar, connecting rod, little rotating shaft, hang sucker, Removable hook, protrusion-dispelling door-plate, turning cylinder, doorframe, Removable hook is connected to by little rotating shaft and hangs on the sucker, doorframe is fixed on the wall of tunnel, it is that shock wave tablet and pull bar are fixed on the rolling disc, pull bar is connected with Removable hook by connecting rod, Removable hook tangles the left end of protrusion-dispelling door-plate, and the right-hand member of protrusion-dispelling door-plate is connected to the top of doorframe by turning cylinder.
Like this, when coal road driving face generation gas burst accident, form very big shock wave, cause the deflection of shock wave tablet, drive rolling disc, pull bar, the connecting rod action, connecting rod hauls Removable hook and is moved to the left, and the left end of protrusion-dispelling door-plate loses the support of hook, hurtles down by deadweight, cover on doorframe, the tunnel is closed, stoped outstanding energy unofficial biography, avoid outstanding gas and coal to feed through to other area, outstanding influence basin narrows down between this device and the driving face, prevent the expansion of contrary wind and accident, reduced economic loss, ensured miner's life security.Have characteristics such as simple in structure, safe and practical, that effect is obvious.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model comprises: shock wave tablet 1, rolling disc 2, pull bar 3, connecting rod 4, little rotating shaft 7, hang sucker 6, Removable hook 8, protrusion-dispelling door-plate 12, turning cylinder 15, doorframe 14, rolling disc 2 is fixed on the wall of tunnel for the garden plate-like, hanging sucker 6 is fixed on the back 13, Removable hook 8 is connected to by little rotating shaft 7 and hangs on the sucker 6, doorframe 14 is fixed on the wall of tunnel, and Removable hook 8 can rotate.Shock wave tablet 1 and pull bar 3 are fixed on the rolling disc 2, shock wave tablet 1 leaves certain distance with the bottom, tunnel, so that ventilate, the angle between shock wave tablet 1 and the pull bar 3 is arranged to 135 degree and is advisable, at ordinary times shock wave tablet 1 is sling, be convenient to walking and vehicle pass-through.Pull bar 3 is connected with Removable hook 8 by connecting rod 4, and Removable hook 8 tangles the left end of protrusion-dispelling door-plate 12, and the right-hand member of protrusion-dispelling door-plate 12 is connected to the top of doorframe 14 by turning cylinder 15.Protrusion-dispelling door-plate 12 adopts wood materials to be processed into, and produces spark in the time of can avoiding protrusion-dispelling door-plate 12 with the doorframe collision.Connecting rod 4 adopts round steel to make, and for the lead that guarantees that shock wave tablet 1 action response time and protrusion-dispelling door-plate 12 fall, the length of connecting rod is that the centre is provided with pulley and hangs about 10 meters, avoids connecting rod long sagging.On back, be fixed with fixed pulley 10, be fixed with movable pulley 9 on protrusion-dispelling door-plate 12, an end of pull rope 11 is fixed on the back 13, and the other end is fixed on the hand winch 16 by fixed pulley and movable pulley, so that after protrusion-dispelling door-plate 12 cuts out, utilize hand winch to open easily.In order to guarantee that Removable hook 8 tangles the solid and reliable property of protrusion-dispelling door-plate 12, make that again connecting rod drives the Removable hook quick acting, and the protrusion-dispelling door-plate is fallen smoothly when generation gas is outstanding, Removable hook 8 is provided with counterweight 5, regulates counterweight 5 and makes it be in proper states.Removable hook and hand winch are provided with night bolt, utilize night bolt with Removable hook 8 and hand winch 16 lock jails at ordinary times, prevent that unexpected the moving of Removable hook from making the protrusion-dispelling door-plate fall to influencing safety, blow out and by the whipper-in miner shock wave tablet is put down when withdrawing, again night bolt is pulled out, can make this device in running order.
