Safe escape device used in tunnel

Abstract

The invention provides a safety escape device used in a tunnel, and relates to the field of tunnel escape equipment. The safety escape device comprises a base, two first protection plates are fixedly connected to two sides of the top of the base, four roller wheels are fixedly connected to the bottom of the base, the four roller wheels are fixedly connected to four corners of the bottom of the base, a check block is arranged above the base, the check block is in a semi-cylinder shape, two second protection plates are fixedly connected to the two sides of the bottom of the check block, and the inner sides of the first protection plates are attached to the outer sides of the second protection plates. According to the safe escape device used in the tunnel, when the safe escape device is not used at ordinary times, a first sliding block and a second sliding block are arranged on the two sides of a double-end motor, so that a supporting column at the top of the first sliding block is very close to a supporting column at the top of the second sliding block, and at the moment, under the action of a limiting column at the top of the supporting column and an inverted-V-shaped limiting groove in a limiting plate, and the limiting plate is in contact with a bottom plate at the lowest position.

Description

technical field [0001] The invention relates to the technical field of tunnel escape equipment, in particular to a safety escape device used in tunnels. Background technique [0002] For a long time, once a landslide occurs in a coal mining area or a mine that has not yet been firmly supported, several miners are often blocked in the tunnel by the collapsed rubble and cannot rely on self-help to survive. Moreover, although external rescuers tried their best to dig through the landslide and rescue the trapped people as soon as possible, due to objective reasons and limited conditions, it was difficult to achieve the rescue goal in a short time. With the passage of time, most of the miners who are blocked in the mine can hardly survive without the necessary conditions for survival, which will cause irreparable losses to the miners' families, enterprises and even society. [0003] According to an escape device used in tunnel construction provided by Chinese Patent No. CN201078...

AI Technical Summary

Problems solved by technology

[0004] However, the escape device proposed in this reference document is used in tunnel construction. The escape channel is made of several metal pipes, which are moved by pulleys and rails. The metal pipes must be thicker to be able to bear landslides. , the weight of the escape channel is very heavy, and the escape channel moves through the rails. During installation, the rails need to be erected first, which increases the amount of work, and the installation speed is slow
