Bracket-type angle-adjustable escape pipeline

Abstract

The invention relates to a bracket-type angle-adjustable escape pipeline comprising a bracket and an escape pipeline body. The bracket comprises two parallel supporting frames; three through holes are formed in the upper portion of each supporting frame at intervals; pin holes are formed in the positions, corresponding to the through holes in the two sides, of the side wall of each supporting frame; two sliding rods are coaxially and slidably mounted in the through holes in the two sides correspondingly; pin holes are also formed in the sliding rods; and pin shafts coaxially penetrate through the pin holes of the supporting frames and the pin holes of the sliding rods to realize positioning of the sliding rods and the supporting frames. An adjusting rod is coaxially mounted in each through hole in the middle; engaging teeth are arranged on one side of each adjusting rod; an engaging wheel is mounted in the position, on one side of the through hole in the middle, in each supporting frame in a hinged mode; the engaging wheels are engaged with the engaging teeth on the adjusting rods; the engaging wheels are rotated to adjust the heights of the adjusting rods; and a handle is coaxially and fixedly mounted on each engaging wheel. A supporting head of the bracket-type angle-adjustable escape pipeline is provided with two adjusting lugs, by adjusting the two adjusting lugs, the escape pipeline can adapt to supporting of pipelines of different diameters, different requirements are met, and after one bracket is manufactured uniformly, different working conditions can be adapted simultaneously.

Description

technical field [0001] The invention belongs to the field of escape, in particular to a bracket type escape pipeline with adjustable angle. Background technique [0002] During the construction of tunnels and mines, due to the complex geology and other factors, landslides may occur from time to time, among which the door-closing landslide has the most serious consequences, once it occurs, it will seriously affect the life safety of the construction personnel in the cave. Therefore, in view of the collapse phenomenon in roadway and tunnel construction, in order to avoid casualty accidents as much as possible and reduce unnecessary economic losses, it is very important to set up tunnel escape pipelines. [0003] According to the requirements of relevant domestic documents, when the cumulative deformation of the surrounding rock exceeds 100mm in the section of the surrounding rock of level V of the tunnel and the section with a very high risk of collapse after risk assessment a...

AI Technical Summary

Problems solved by technology

[0004] In the process of pipeline construction, tunnels with different depths will have different heights, and the escape pipeline needs to be turned at a certain angle to adapt to the tunnel conditions for escape. The existing escape pipeline is generally turned by a transfer method similar to a water pipe, which is very inconvenient to operate. , which is more unsuitable for the turning of shorter tunnels
