Embodiment Construction

[0010] Such as figure 1 , 2 As shown, the double-buffer forced reset explosion-proof door for inclined shaft and flat shaft includes: frame 1, installed on the center wedge beam 7 of frame 1, two doors 2 installed on the wedge beam 7 through hinges 9 and torsion springs 10, and wire ropes 8 The counterweight 5 is connected to the two doors 2 through the pulley block 4; the two doors 2 are embedded with a number of gas springs 6, and the two doors 2 are also equipped with a number of foam aluminum buffer devices 11; Page 9 is provided with a gear synchronization mechanism 3 for two doors; a wedge beam 7 is provided on the frame 1; a pin-type locking mechanism 12 is provided between the frame 1 and the two doors 2, and the lock The pin of the mechanism 12 is a nylon rod.

[0011] When the pressure is relieved, the two doors 2 rotate around the hinge 9 and collide with a number of gas springs 6 embedded in the door. The gas is compressed and absorbs energy to achieve a buffer effect...

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 [0001] The invention relates to a coal mine ventilation safety facility, in particular to an explosion-proof door with a gas buffer device and a reset mechanism for inclined shafts and flat shafts. Background technique [0002] The explosion-proof door of the ventilation shaft in the existing coal mine ventilation safety facilities is an ordinary ordinary door type explosion-proof door with steel structure. Once a underground explosion occurs in a coal mine, the explosion-proof door is easily damaged or fly away from the wellhead. Unable to reset, this will cause the underground coal mine to be unable to resume ventilation in a short time, so that harmful gases cannot be discharged, so that rescuers lose time for rescue and rescue. At the same time, it also seriously endangers the life and safety of underground workers, resulting in damage after the accident. The disaster expanded. For this reason, coal mines urgently need to research and develop safer explosion-...
