Rescue capsule partition sealing door

Abstract

The invention relates to a rescue capsule partition sealing door, belongs to the technical field of mine rescue capsule sealing doors and aims at providing the rescue capsule partition sealing door which is simple and light-weight in structure, simple and labor-saving to operate and reliable in sealing. The adopted technical scheme is as follows: a door is mounted on a door frame through a hinge,a rubber sealing strip is arranged at the combination part of the door and the door frame, a hand wheel shaft mounting seat is welded on the door, a hand wheel shaft is mounted in the hand wheel shaft mounting seat, a driving disc is arranged at one end, close to the inner side of the door, of the hand wheel shaft, four connecting rods are hinged on the driving disc, each connecting rod is hingedwith a locking rod, and operation and control hand wheels are arranged at the two ends of the hand wheel shaft; and a guide block is welded on the door, the locking rods penetrate holes on the guide block, four compressing wedge blocks are welded in the positions corresponding to the locking rods of the door frame, and the compressing wedge blocks are matched with the locking rods. The rescue capsule partition sealing door is mainly used for partitions of rescue capsules.

Description

technical field [0001] The rescue cabin partition sealing door of the invention belongs to the technical field of mining rescue cabin sealing doors. Background technique [0002] The design of the rescue cabin generally focuses on the design of the cabin section and the performance of the front hatch, while ignoring the design of the partition airtight door. First of all, the existing partition airtight door and the door frame adopt a single hinge connection method, and only one or two points are locked, and the locking is unreliable; at the same time, when the partition airtight door is closed, the door frame and the door are squeezed on one side , resulting in uneven stress on the sealing strip between the door frame and the corresponding position of the door, which is prone to gaps and lacks good sealing. Secondly, the existing partition hermetic door ignores the sealing of the rotating shaft at the inside and outside opening handles. [0003] When a mining accident occ...

AI Technical Summary

Problems solved by technology

When the escape personnel open the front hatch and enter the transition cabin, a large amount of toxic and harmful gases and dust may rush into the transition cabin, and the escape personnel may also carry toxic and harmful gases and dust on their bodies. Poor sealing will cause toxic and harmful gases and dust to enter the survival cabin, endangering the health and even life of the escape personnel
