Safe and reliable escape device for subway construction

Abstract

A safe and reliable escape device for subway construction comprises a transverse pipe, wherein an inlet and outlet is formed in the transverse pipe, a sealing cover is installed at the inlet and outlet in a matched mode, first transverse sliding grooves distributed in the left-right direction are fixedly formed in the upper portion of the transverse pipe, second transverse sliding grooves distributed in the left-right direction are fixedly formed in the lower portion of the transverse pipe, the first transverse sliding grooves are connected with the corresponding second transverse sliding grooves on the lower side through a plurality of first vertical sliding grooves, the second vertical sliding grooves are fixedly formed in the corresponding first transverse sliding grooves, the lower ends of the second vertical sliding grooves are hinged to mounting baffles through torsional springs, first rolling wheels are mounted in the second vertical sliding grooves, second rolling wheels are mounted in the first vertical sliding grooves in a matched mode, and the second rollers are rotatably mounted on the corresponding supporting plates. Supporting plates assisting personnel in moving in the transverse pipe are arranged, wounded personnel and constructors can conveniently and rapidly move in the transverse pipe, the plurality of supporting plates are arranged, the use requirements of the constructors at different entrances and exits are met, the supporting plates can be supplemented in time, and the use requirements of a large number of constructors are met.

Description

technical field [0001] The invention belongs to the field of escape pipelines, in particular to a safe and reliable escape device for subway construction. Background technique [0002] With the rapid development of railways and expressways, the scale and difficulty of tunnel construction are also increasing, and tunnel collapse accidents continue to occur. These accidents have caused varying degrees of property and casualty losses to tunnel construction, seriously affecting the construction period. For this reason, escape passages must be set up during tunnel construction, but the existing escape pipes are just a few hard pipes connected together. After a danger occurs, the trapped people need to climb out of the pipes by themselves, which improves the escape efficiency. Low, and it is more difficult for injured personnel to crawl in the pipeline, personnel cannot escape in time, there are serious hidden dangers, and it cannot meet actual needs, so we invented a safe and rel...
