Abstract

The invention discloses an underground rescue capsule quick-opening door and belongs to the field of machinery. The underground rescue capsule quick-opening door comprises a door body, a hinge shaft and a capsule wall, wherein the door body comprises an outer door body, an inner door body, a torsional spring, a clamping ball, a spring and a switch. The inner door body has the trend of overturningtowards a capsule. The inner door body is provided with the outer door body connected with inner door body to form a whole, and the outer door body is relatively stuck under the effect of the clampingball supported by the spring. When the clamping ball can be compressed into the capsule wall when the outer door body is opened, a switch arranged in the capsule wall is triggered, and a lamp in thecapsule is controlled to be turned on. Due to the structure, persons can quickly enter the rescue capsule when a mine disaster occurs, good airtightness is kept, and the safety of the persons is protected.

Description

technical field [0001] The invention belongs to the field of mining machinery, and in particular relates to an underground rescue cabin door. Background technique [0002] As a big energy consumer in China, coal occupies an absolute proportion of nearly 70% in the overall pattern of energy production in my country. Although my country's coal production only accounts for 1 / 3 of the world's coal production, the death toll in coal mine accidents accounts for 4 / 5 of the world's coal mine accident deaths. Out of every 20 coal mine disasters that resulted in the highest number of deaths in the world, 8 occurred in China. Frequent mine disasters not only caused the breakdown of many families, but also seriously affected China's international image. [0003] The mine rescue cabin is a new type of life-saving device that combines active self-rescue and external rescue during emergency avoidance. Mine rescue cabins are generally placed near the coal mine mining face, main transport ...
