Abstract
Double-buffering forced reset explosion doors of an inclined well and a horizontal well relate to ventilating safety facilities of coal mines and resolve the problem that existing explosion doors are easy to damage and cannot be reset. The double-buffering forced reset explosion doors of the inclined well and the horizontal well are characterized in that a plurality of gas springs are embedded in the two doors, and a plurality of foamed aluminum buffer devices are further arranged on the two doors. A pin shaft locking mechanism is arranged between a frame and the two doors, and a pin shaft of the pin shaft locking mechanism has the effect of a safety pin. Gear synchronous mechanisms of the two doors are arranged on a rotating shaft. A tapered beam is arranged on the frame. The double-buffering forced reset explosion doors are used for the inclined well and the horizontal well of the coal mines and have a double-buffering forced reset function.
Description
Technical field
The present invention relates to the coalmine ventilation safety device, particularly inclined shaft and horizontal well have the explosion proof door of gas buffer and resetting-mechanism.
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 shortcoming of prior art, a kind of inclined shaft and horizontal well double buffering forced resetting explosion proof door are provided, solve existing explosion proof door and destroy easily and the problem that can not in time reset.
The present invention realizes through following technical scheme:
Inclined shaft and horizontal well double buffering forced resetting explosion proof door; Comprise: framework; Be installed in the tapered beam of frame center, fan door through two of hinge and torsion spring installation on the tapered beam, and pass through an assembly pulley and two a fans counterweight that is connected respectively with wire rope; It is characterized in that: be embedded with some gas springs in the said two fan doors, on the said two fan doors some foamed aluminium buffers be housed also; Said hinge is provided with the gear synchronization mechanism of two fan doors; Be provided with the pin type blocking mechanism between said framework and the said two fan doors, the bearing pin of said blocking mechanism is a nylon rod.
The present invention is owing to inlay gas spring in the door, and extruding absorbs energy when door is opened, and does not need other dress to hold and hits bearing; Because door is gone up the foamed aluminium buffer is installed, after gas spring is compressed to certain stroke, is absorbed dump energy, reach the effect of secondary buffer; Because torsion spring and counterweight combine, after blower fan stopped, door leaf was opened certain angle automatically and is carried out natural ventilation under the counterweight effect, and when blower fan was opened, door was thoroughly closed under action of negative pressure; After well shooting took place, under the effect of impact generated by explosion ripple or high pressure draught, door was opened release, after the effect Xiamen of torsion spring resets to certain angle, leaned on the complete adhesive of negative pressure after the release; Because framework is provided with tapered beam, play shunting action, reduce impact to beam; Owing to the gear synchronization mechanism that is provided with two fan doors, the assurance door is opened simultaneously and is closed simultaneously, when avoiding the stressed back generation of door speed than big inequality, is biased on one side, and the active area when increasing secondary pulse causes damages such as door-hinge, influences normally to reset; Because the pin type blocking mechanism is set, utilize bearing pin when inverted ventilation, lock door, simple and reliable, if contingency is blasted during inverted ventilation, safety pin is cut off, but still release.The present invention is used for colliery inclined shaft and horizontal well, has double buffering forced resetting function.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The present invention is further described through embodiment below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 1, shown in 2; Inclined shaft and horizontal well double buffering forced resetting explosion proof door comprise: framework 1 is installed in framework 1 center tapered beam 7; Pass through the two fan doors 2 that hinge 9 and torsion spring 10 are installed on the tapered beam 7, and pass through assembly pulley 4 and two with wire rope 8 and fan the counterweight 5 that door 2 is connected respectively; Said two fan doors are embedded with some gas springs 6 for 2 li, on the said two fan doors 2 some foamed aluminium buffers 11 are housed also; Said hinge 9 is provided with the gear synchronization mechanism 3 of two fan doors; Said framework 1 is provided with tapered beam 7; Be provided with pin type blocking mechanism 12 between said framework 1 and the said two fan doors 2, the bearing pin of said blocking mechanism 12 is a nylon rod.
When release, two fan doors 2 wrap page or leaf 9 revolutions, and through the some gas springs 6 dislocation collisions in being embedded in, gas is compressed the absorption energy, reaches the effect of buffering, and do not need in addition dress to hold to hit bearing; Be contained in the some foamed aluminium buffers 11 mutual impact absorption dump energy after gas spring 6 is compressed to certain one stroke on the door, reach the effect of double buffering; Counterweight 5 usefulness wire rope 8 are connected with two fan doors 2 through assembly pulley 4, guarantee two fan doors 2 after blower fan stops, and lean on counterweight 5 that two fan doors 2 are opened certain angle automatically and carry out natural ventilation, and when blower fan was opened, door was thoroughly closed under action of negative pressure; After blasting, under the effect of impact generated by explosion ripple or high pressure draught, two fan doors 2 are opened venting of dust explosion, after the high pressure draught that produces of waiting to explode, after two fan doors 2 reset to certain angle under the effect of torsion spring 10, lean on the blower fan negative pressure to reset fully; 7 shunting actions of tapered beam on the framework reduce the impact to beam; Gear synchronization mechanism 3, the assurance door is opened simultaneously and is closed simultaneously, when avoiding the stressed generation of door uneven greatly, is biased on one side, and the active area when increasing secondary pulse causes damages such as door-hinge, and influence normally resets; Pin type blocking mechanism 12 utilizes bearing pin when inverted ventilation, to lock door, just in case blast, cut off when bearing pin surpasses certain pressure during like inverted ventilation, but safe unloading pressure after blast, is changed bearing pin, and is simple and reliable.
