A hoop-type pipeline climbing and overhauling machine

Abstract

A hoop type maintaining machine capable of climbing a pipeline comprises a buckle hoop arm and a jacking pressing hoop arm, a positioning hoop frame is arranged at the bottom end of the buckle hoop arm, an auxiliary hoop frame is arranged at the top end of the buckle hoop arm, the positioning hoop frame and the auxiliary hoop fame have the same structure and each comprises a pipe-holding frame body, an opening and closing buckle plate and a pipe-holding rotating seat, a positioning jacking pressing frame is arranged at the bottom end of the jacking pressing hoop arm, the positioning jacking pressing frame is matched with the positioning hoop frame in a buckled mode, an auxiliary jacking pressing frame is arranged at the top end of the jacking pressing hoop arm, and the auxiliary jacking pressing frame is matched with the auxiliary hoop frame in a buckled mode. According to the hoop type maintaining machine capable of climbing the pipeline, the buckle hoop arm is matched with the jacking pressing hoop arm to tightly hold or loosen the outer wall of the pipeline and climbs the pipeline in a stretching and telescoping mode, a maintaining arm lever is matched with a maintaining tool, a flue gas monitoring probe and the like to conduct maintaining, real-time detection and other work on the pipeline, the maintenance cost is reduced, and the safety accident that a maintenance worker falls from the height can not happen. Therefore, the hoop type maintaining machine capable of climbing the pipeline is reasonable in structure and easy to manipulate.

Description

technical field [0001] The invention belongs to an overhauling machine, in particular to a hoop-type pipeline climbing and overhauling machine capable of climbing and moving on a pipeline. Background technique [0002] In industrial production plants, pipelines are commonly used to transport various chemical liquids and gases. These pipelines are erected on the top of the pipeline frame. The outer wall has been eroded by wind, rain and gas for a long time, and the inner cavity is corroded by chemicals. Therefore, the pipe walls and Various equipment and instruments installed on the pipeline are particularly vulnerable to damage. In the prior art, scaffolding is set up under and around the pipeline, and maintenance workers climb to the top of the pipeline bracket through the scaffolding to perform pipeline maintenance work, and install and replace equipment and instruments, which not only requires more scaffolding materials, but also consumes more For a long time, it is also...
