Abstract

The invention provides a fireproof and explosion-proof door. The fireproof and explosion-proof door comprises olivary door bodies, supporting ribs, reinforcing ribs and an oxygenating device, wherein the olivary door bodies form a cavity; pin shafts and hasps are arranged on the inner wall of the cavity; the oxygenating device is positioned in the cavity; the reinforcing ribs are arranged on a panel of each olivary door body; two reinforcing ribs are arranged on the panel of each olivary door body in a cross way; a ball bearing is arranged at one end of each supporting rib and is connected with the corresponding pin shaft in a matching way; the other end of each supporting rib is clamped on the corresponding hasp. The olivary door bodies form the cavity which provides a temporary shelter for operators who cannot timely escape from a hoistway; the oxygenating mechanism is arranged in the cavity so as to prolong the survival time of the operators and provide time for rescue; the explosion-proof strength of the integral structure is enhanced by the supporting ribs and the reinforcing ribs, so that the thicknesses of plates are reduced, the wear rate of an opening-closing mechanism of the door body is reduced, and the service life of equipment is prolonged; the supporting ribs can be hung on the door body at normal times; when accidents occur, the supporting ribs at two sides are connected to support the door body.

Description

technical field [0001] The invention relates to the technical field of safety products, in particular to a fireproof and explosion-proof door. Background technique [0002] At present, the preparation materials of explosion-proof doors mostly use increasing the thickness of metal plates to improve the explosion-proof strength, which has the disadvantages of being relatively heavy and expensive. At the same time, heavy plates will cause great damage to the opening and closing transmission mechanism after being used for a period of time, which will lead to deviations in the opening and closing coordination of the explosion-proof door, and in severe cases, the explosion-proof door will not be able to close normally. Contents of the invention [0003] The invention aims to solve the problems of the existing explosion-proof doors with single structure, thick plates and short service life, and provides a fire-proof and explosion-proof door with improved explosion-proof strength ...
