Impact-resistant flat bottom type ultra-high molecular weight polyethylene escape pipeline

Abstract

The invention discloses an impact-resistant flat bottom type ultra-high molecular weight polyethylene escape pipeline. The impact-resistant flat bottom type ultra-high molecular weight polyethylene escape pipeline comprises a tunnel and an escape pipeline body; the escape pipeline body is fixed to one side of the ground plane inside the tunnel; a flat bottom plate is arranged at the bottom of theescape pipeline body, and an escape sliding plate is arranged at the upper end of the flat bottom plate; supports are fixedly connected to the periphery of the lower end of the escape sliding plate, and sliding wheels are arranged at the bottoms of the supports; an escape rope is arranged in the escape pipeline body, and the two ends of the escape rope are fixed to the two ends of the escape pipeline body through fixing pieces; a fixing frame is connected to the outer wall of the escape rope in a sleeving mode, and the bottom of the fixing frame is fixedly connected with a handle; a limiting block is arranged on the inner wall of the upper end of the fixing frame through a limiting groove, and a ball is arranged at the lower end of the limiting block; a first L-shaped protection plate anda second L-shaped protection plate are arranged outside the escape pipeline in sequence from inside to outside. The impact-resistant flat bottom type ultra-high molecular weight polyethylene escape pipeline is simple in structure, easy to operate, small in weight, convenient to mount and meanwhile capable of increasing the escape probability of escape personnel.

Description

technical field [0001] The invention relates to the technical field of escape pipes, in particular to an impact-resistant flat-bottomed ultra-high molecular weight polyethylene escape pipe. Background technique [0002] Most of the escape pipes on the market are large-diameter steel pipes. This kind of steel pipe is expensive and heavy. The construction process of placing it in the tunnel is very difficult and inconvenient. It requires a lot of labor to operate synchronously. , It is also necessary to install additional fixing equipment to fix the position of the pipeline to prevent the pipeline from rolling and deviating from the original position. The operation process is complicated, the work efficiency is low, and the construction progress is slow. In view of the above reasons, the structure of the existing escape pipeline needs to be improved. Contents of the invention [0003] In order to solve the problems mentioned above in the background technology, the present i...
