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

Abstract

The invention discloses an impact-resistant flat-bottomed ultra-high molecular weight polyethylene escape pipe, which includes a tunnel and an escape pipe. The escape pipe is fixed on one side of the ground plane inside the tunnel, and the bottom of the escape pipe is provided with a flat bottom plate. And the upper end of the flat bottom plate is provided with an escape slide, the lower end of the escape slide is fixedly connected with a bracket around it, and the bottom of the bracket is provided with a pulley, and an escape rope is arranged in the escape pipe, and the two ends of the escape rope pass through the fixing parts It is fixed at both ends of the escape pipe, the outer wall of the escape rope is sleeved with a fixed frame, and the bottom of the fixed frame is fixedly connected with a handle, and the inner wall of the upper end of the fixed frame is provided with a limit block through a limit groove, and the limit block A ball is provided at the lower end of the escape pipe, and a first L-shaped protective plate and a second L-shaped protective plate are sequentially provided on the outside of the escape pipe from the inside to the outside. The invention has the advantages of simple structure, easy operation, light weight and convenient installation, and can greatly improve 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...
