AI Technical Summary

Technical Problem

Existing pipe vibration damping structures typically use corrugated pipes, which makes the pipes prone to damage such as cracking or breaking, especially under the influence of vibrations during subway operation.

Method used

By setting connecting frames and pivots on both sides of the pipeline for limiting connection, the pipelines on both sides of the first shock absorber can only swing around the pivot axis. Combined with the scissor rod and pin to form a scissor frame, the pipeline's undirected vibration is limited. At the same time, pressure sensors and moving mechanisms are used to monitor the pipeline status and replace ruptured shock absorbers in a timely manner.

Benefits of technology

It effectively limits the swing and vibration amplitude of the pipeline, preventing rupture or breakage caused by long-term vibration or excessive vibration intensity, and ensuring the stability and safety of the pipeline.

Abstract

This application relates to a pipe vibration damping installation structure, specifically within the technical field of pipe connection structures. It includes a pipe and a first damping tube, with both ends of the first damping tube connected to the pipe. Connecting frames are fixed to the pipes on both sides of the first damping tube, and these connecting frames are hinged together via pivots. When the subway travels through the transfer level, the vibrations generated are transmitted to the pipe, causing it to vibrate. This design ensures that the pipes on both sides of the first damping tube can only swing relative to each other around the axis of the pivot, preventing uncontrolled vibrations. Thus, while ensuring the first damping tube effectively dampens vibrations, the design limits the amplitude of pipe swing to a certain extent, preventing damage such as pipe rupture or breakage caused by prolonged vibration or excessive vibration intensity.
