Movable hard rescue capsule emergency door

Abstract

The invention relates to a movable hard rescue capsule emergency door, which comprises a door wall plate, a door plate, a heat insulating material, a crossed latch, a fixed sleeve, a conical sleeve, a door shaft, two hand wheels, an inner lining plate, a door frame, a first limiting pin and a second limiting pin, wherein a cavity between the inner lining plate and the door plate is filled with the heat insulating material; the crossed latch is positioned outside the inner lining plate; a through hole is formed in the centers of the door plate, the inner lining plate and the heat insulating material; the fixed sleeve is welded in the through hole of the door plate; the door shaft penetrates through the conical sleeve, the crossed latch and the fixed sleeve from inside to outside of a capsule in sequence; the conical sleeve corresponds to a conical hole in the top of a nut and the sizes are the same; the two ends of the door shaft are provided with one hand wheel respectively; the door plate is provided with the first limiting pin on the inner side of the capsule; and the door wall plate is provided with the second limiting pin on the inner side of the capsule. The movable hard rescue capsule emergency door has the characteristics of better heat insulating and sealing effects and high reliability and can be widely applied to the field of mining.

Description

technical field [0001] The invention relates to heat insulation and sealing technology, in particular to a movable emergency door of a hard rescue cabin. Background technique [0002] The emergency door is an important part of the removable hardware rescue cabin used in the coal industry. When the main cabin door cannot be opened, it is used as an emergency passage for entering and exiting the rescue cabin. The sealing and heat insulation effect of the emergency door is the performance of the emergency door. An important indicator of good or bad. When a catastrophe occurs in the mine, severe high temperature and harmful gas enter the cabin under the condition of poor heat insulation and sealing effect of the emergency door, which increases the cost of environmental treatment in the cabin; in the prior art, the locking device of the emergency door adopts four The rod mechanism or its deformation mechanism can better realize the multi-point locking of the emergency door, but ...

AI Technical Summary

Problems solved by technology

When a catastrophe occurs in the mine, severe high temperature and harmful gas enter the cabin under the condition of poor heat insulation and sealing effect of the emergency door, which increases the cost of environmental treatment in the cabin; in the prior art, the locking device of the emergency door adopts four The rod mechanism or its deformation mechanism can better realize the multi-point locking of the emergency door, but the locking force is small and the sealing effect is poor; if multiple four-bar linkage mechanisms are used in parallel, high manufacturing and assembly precision is required, but the cabin The body is a weldment, with large deformation, and multiple four-bar linkages are easy to interfere, and the reliability is low

[0003] It can be seen that in the prior art, the emergency door has the problems of heat insulation, poor sealing effect and low working reliability.
