Anti-flaming and anti-explosion sliding door device for down-hole refuge chamber

Abstract

The invention discloses an anti-flaming and anti-explosion sliding door device for a down-hole refuge chamber. The device comprises an anti-flaming and anti-explosion sliding door and a guide groove door frame which are arranged on the inner side and the outer side of a refuge chamber anti-explosion door wall. The anti-flaming and anti-explosion sliding door is embedded into the guide groove door frame, pulleys are embedded into the upper side and the lower side of the anti-flaming and anti-explosion sliding door, an upper guide groove and a lower guide groove of the guide groove door frame are attached to the pulleys, and absorption control valves are arranged on the left side and the right side of the guide groove door frame. The anti-flaming and anti-explosion sliding door is more easily opened and closed through rolling friction force. The problems that an anti-flaming and anti-explosion door deforms under explosive shock and is not easily opened and closed, and a handle of a common anti-explosion door is easily damaged are solved, when a down-hole accident happens, the anti-flaming and anti-explosion sliding door is easily opened and closed under the condition that no power supply or any external power source is needed, the two-layer sliding door can effectively separate explosive shock waves and toxic and hazardous gas generated by explosions, and people in the accident can rapidly enter the refuge chamber.

Description

Technical field [0001] The invention relates to the technical field of mine safety rescue safety guarantee facilities and equipment, in particular to a flame-retardant explosion-proof sliding door device used for underground refuge chambers. Background technique [0002] Existing underground mining mines generally require refuge facilities (refuge chambers, rescue cabins, refuge shelters). The general refuge chambers are located near the pit bottom, sometimes at a depth of 600 to 900 meters, and underground workers cannot escape the site. You can take refuge inside and wait for rescue. These refuge facilities are generally enclosed spaces, connected to the outside world through explosion-proof doors. Existing explosion-proof doors are generally opened or closed manually by means of mechanical transmission. This method makes it easy for underground workers to waste a lot of time on opening and closing doors in the event of an emergency, which may cause traditional explosion-proof...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a flame-retardant explosion-proof sliding door device for underground refuge chambers, which solves the problems that the flame-retardant explosion-proof door is deformed under the impact of the explosion and is not easy to open and close, and the handle of ordinary explosion-proof doors is easily damaged. When an underground accident occurs, the flame-retardant and explosion-proof sliding door can be easily opened and closed without power supply or any external power source. The personnel quickly entered the refuge chamber
