Safe escape device used in coal mine or tunnel

Abstract

The invention relates to a safe escape device used in a coal mine or a tunnel, which comprises an escape pipe, support frames and slide support feet, wherein the length of each section of the escape pipe is set into 8 to 12 m, the support frames are correspondingly arranged in the vertical direction of one side of each section of the escape pipe at intervals, escape holes are correspondingly formed on the side parts of the escape pipe between the support frames, one side of the inner wall of the escape pipe positioned at the side of the escape holes is uniformly provided with pedaling holes at intervals, the bottom of the support frames is connected and provided with the sliding support feet through pin shafts to be glidingly matched with the support frames, both ends of the pin shafts are respectively positioned at the lower parts of the support frames in corresponding arrangement through screw nuts and gaskets, and in addition, both ends of the escape pipe are respectively matched and provided with a 60-degree joint pipe, a 90-degree joint pipe, a three-way joint pipe and a four-way joint pipe with the same caliber of pipe openings. In the installation process, a plurality of sections of the escape pipe and the joint pipes of different angles are connected for establishing an escape system. The invention has the advantages of simple structure and reasonable design, persons in distress can pass the collapse parts through crawling in the pipe to realize the self saving, and the effects of safety and reliability are realized.

Description

technical field [0001] The invention relates to a safety escape device, in particular to a safety escape device used in coal mines or 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. Contents of the invention [0003] The purpose of the present invention is to change the status quo and provide a ...
