Abstract
A kind of mining automatic closedown anti-explosion safety door, field of explosion, its structure is: door closer body (1) is fixed on anti-explosion safety door board (3), and the pull bar other end of door closer body (1) to be fixed on doorframe on (2).The beneficial effects of the utility model are: the utility model effectively stops the diffusion of the particles such as dust; in the situation such as to blast; can effectively stop shock wave to the impact of personnel in the pit or equipment; good protective effect is had to personnel's property safety; and the utility model structure is simple; security performance is good, and cost is low, firm.
Description
one, technical field
The present invention relates to field of explosion, particularly the mining automatic closedown anti-explosion safety door of one.
two, background technology
In mine when happening suddenly blast or gas explosion, the shock wave that blast produces may damage underground equipment, especially ventilation equipment, and the dust that shock wave produces likely can only be used for flame proof effect to general explosion proof door, the dust that explosion wave produces cannot be isolated, explosives magazine belongs to key protection region, need carry out effective locking.
three, summary of the invention
The invention provides a kind of mining automatic closedown anti-explosion safety door for the problems referred to above, its structure is: door closer body (1) is fixed on anti-explosion safety door board (3), and the pull bar other end of door closer body (1) to be fixed on doorframe on (2).
Using method of the present utility model is such: open after people enters or goes out when anti-explosion safety door board (3) and forget at closing time, door-plate is retracted initial position by the Hui Li of spring by the pull bar being fixed on the door closer body (1) on doorframe on (2), shut the door, like this roadway travel fatigue particle would not from door while be diffused into the another side of door, be arranged on explosives magazine door or the position be arranged on a certain distance from work plane, in the situation such as to blast, can effectively stop shock wave to the impact of personnel in the pit or equipment, good protective effect is had to personnel's property safety.
Beneficial effect of the present invention is: the utility model effectively stops the diffusion of the particles such as dust; in the situation such as to blast; can effectively stop shock wave to the impact of personnel in the pit or equipment; good protective effect is had to personnel's property safety; and the utility model structure is simple; security performance is good, and cost is low, firm.
Four, accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, door closer body, 2, doorframe, 3, door-plate.
Four,
detailed description of the invention
Embodiment 1, a kind of mining automatic closedown anti-explosion safety door, its structure is: door closer body (1) is fixed on anti-explosion safety door board (3), and the pull bar other end of door closer body (1) to be fixed on doorframe on (2).Opening after people enters or goes out when anti-explosion safety door board (3) forgets at closing time; door-plate is retracted initial position by the Hui Li of spring by the pull bar being fixed on the door closer body (1) on doorframe on (2); shut the door; like this roadway travel fatigue particle would not from door while be diffused into the another side of door; be arranged on explosives magazine door or the position be arranged on a certain distance from work plane; in the situation such as to blast; shock wave effectively can be stoped the impact of personnel in the pit or equipment, have good protective effect to personnel's property safety.
