Embodiment 1

[0019] The present embodiment is a sealed door of a mining rescue cabin, comprising a door panel 2, a speed reduction mechanism 4, a lock body mechanism, a sealing ring 16 and a sealing ring pressing member, two sealing rings 16 are installed along a circle of the door panel 2, and the door panel There is a reduction mechanism 4 and a lock body mechanism on the 2, and the lock head in the lock body mechanism is driven by the worm and gear of the reduction mechanism 4 to realize the sealing and locking between the airtight door 2 and the door frame 1. The sealing ring pressing part is fixed on the door panel for a week, and the two sealing rings 16 are located in the mounting grooves of the sealing ring pressing part. On the door panel 2, there is also fixed a circle of embedding plate 13 with a "concave" shape in cross section. Both side walls of the embedding plate 13 are embedded in the sealing ring 16 . The lock body mechanism of the sealed door of the mine rescue cabin in...

Abstract

The invention discloses a sealing door of a mining rescue capsule. The sealing door comprises a door panel, a decelerating mechanism, a locker mechanism, a transmission mechanism, a clamping and pressing plate, a seal ring pressing member and a seal ring, wherein two bearing plates and an oblique pressing plate of the seal ring pressing member are fixed on a door frame in the way that the bearing plates are engaged with the oblique pressing plate; a mounting groove for the seal ring is formed between the bearing plates and the oblique pressing plate; the clamping and pressing plate is fixed along the periphery of the door panel; the middle upper part of the door panel of the mining sealing door is provided with an emergency exit with an emergency door; the locker mechanism is provided with two sets of lead screws, connecting rods, locking seats and locking heads; a worm wheel and worm transmission mechanism is shared by the two sets of lead screws, connecting rods, locking seats and locking heads; the two lead screws are reverse in rotation direction; and the two ends of each connecting rod are connected with the two locking heads respectively. The sealing door realizes full sealing and provides more chance for personnel to escape; the pressing force to the seal ring is increased and the sealing effect of the sealing door is improved by pressing four points of the seal ring; and the sealing door has the characteristics of simple and reliable structure, convenience of use and low cost.

Description

technical field [0001] The invention relates to the field of mine lifesaving, in particular to a sealed door of a mine lifesaving cabin. Background technique [0002] In order to meet the normal use requirements of the mine rescue cabin, people are equipped with metal airtight doors in the transition cabin of the rescue cabin to facilitate the occurrence of mining accidents, so that the trapped people can easily enter. When the existing metal airtight door is closed, it only depends on the very close plane contact between the periphery of the door and a sealing ring embedded in the corresponding position of the door frame, and the door frame and the door are squeezed by force on one side, causing the door frame to correspond to the door. The sealing ring embedded in the position is not uniformly stressed, and gaps are likely to occur, lacking a good seal, resulting in poor airtightness of the rescue cabin as a whole. When a mining accident occurs, there is a certain pressur...
