Abstract
The utility model relates to an exhaust ventilation anti-explosion door of a coal mine vertical shaft, which comprises a shaft inner wall, a hinge, a foundation base, an anti-explosion door, anti-explosion door opening and closing synchronizing mechanisms and sealing strips, wherein the anti-explosion door comprises four isosceles triangles which are mutually overlapped to form a right rectangular pyramid body, the sealing strips are embedded on mutually lapped places of the anti-explosion door, the anti-explosion door is arranged on the foundation base through a hinge, the foundation base is connected with the shaft inner wall, and the anti-explosion door opening and closing synchronizing mechanisms are arranged on four corners of the foundation base. The exhaust ventilation anti-explosion door has a simple structure, can effectively bear negative pressure generated by a ventilating machine under the normal ventilation condition because of being formed by mutually overlapping the four isosceles triangles, plays a role in sealing a well opening without causing short circuit of a ventilation system, can be immediately opened for releasing or reducing the impact force of the impact waves under the action of impact waves when explosion is caused in a coal mine, and can immediately recover to be the original perfect state after explosion happens.
Description
Technical field:The utility model relates to a kind of coal mine shaft lining exhaust ventilation explosion proof door.
Background technology:At present, traditional explosion proof door structure that use in the colliery is integral type, covers on the well head; When mine was blasted disaster, explosion proof door was dashed by shock wave and flies and gross distortion, is difficult to restore to the original state; The ventilation system cisco unity malfunction has seriously influenced carrying out of disaster rescue work.
Summary of the invention:The purpose of the utility model is to overcome above-mentioned shortcoming; A kind of coal mine shaft lining exhaust ventilation explosion proof door is provided; It has mainly solved traditional explosion proof door structure is integral type, covers on the well head, when mine is blasted disaster; Explosion proof door is dashed by shock wave and flies distortion, is difficult to problems such as reinstatement.The purpose of the utility model is achieved in that coal mine shaft lining exhaust ventilation explosion proof door is by: shaft in wall, hinge, basis seat, explosion proof door, explosion proof door open and close lazy-tongs, weather strip formation.Explosion proof door is four isosceles triangles; Be overlapped to form square cone between them each other, the mutual lap-joint of explosion proof door studs with weather strip, and explosion proof door is installed on the seat of basis through hinge; The basis seat is connected with shaft in wall, on four angles of basis seat explosion proof door open and close lazy-tongs is housed.This product structure is simple, and is reasonable in design, because explosion proof door adopts four isosceles triangles to overlap each other; Under normal ventilation situation, it can effectively bear the negative pressure that ventilation fan produces, and the effect of playing the sealing well head does not cause the ventilation system short circuit; When in mine, blasting, it can in time be opened under the effect of shock wave, releases or reduce the impact force of shock wave; The protection ventilation fan is not destroyed with other ventilation equipment, and after explosion disaster took place, it can return to original serviceable condition in time; The assurance mine ventilation system is normally moved, and helps carrying out of disaster rescue work.
