Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figure 1-3 As shown, a replacement method for a high-altitude vertical corrugated compensator includes the following steps:

[0019] A. Arrange cranes 2 on the open space on both sides of the high-altitude vertical corrugated compensator 1. The crane 2 is a truck crane. One crane 2 hangs the connecting pipe 3 connected to the lower end of the high-altitude vertical corrugated compensator 1. Another crane 2 Lift the cage 4 carrying the operator and make the cage 4 close to the connecting pipe 3 below. The operator uses gas welding to cut a pipe nipple 5 with a length of 450-550mm from the connecting pipe 3 below, and connects the pipe nipple 5 is drawn out, so that there is space when the high-altitude vertical corrugated compensator 1 is dismantled, hoisted and dropped.

[0020] B. Use one crane 2 to hang the lifting lugs on t...

Abstract

The invention discloses a replacement method of a high-altitude vertical ripple compensator. The method comprises the steps of firstly, cutting a short section of a connecting pipeline below the high-altitude vertical ripple compensator, then cutting, so that the high-altitude vertical ripple compensator is separated from the upper connecting pipeline, removing the waste high-altitude vertical ripple compensator, manufacturing a circular installation platform outside a new high-altitude vertical ripple compensator at the same time, then lifting the new high-altitude vertical ripple compensatoron the line, welding the new high-altitude vertical ripple compensator with the upper connecting pipeline, and finally, backfilling and welding the short section of the connecting pipeline, so that the replacement purpose of the ripple compensator can be realized. According to the replacement method, the problem of replacing the high-altitude vertical ripple compensator without an overhaul platform at high altitude is solved, the overhaul period is shortened, the overhaul efficiency is improved, the labor intensity of maintenance workers is greatly reduced, the safety of the maintenance workers is effectively guaranteed in an overhaul process, and the replacement method has the advantages of rapidity and convenience in replacement, high safety, easiness in implementation and high practicability.

Description

technical field [0001] The invention belongs to the technical field of maintenance of environmental protection dust removal equipment in metallurgical plant areas, and in particular relates to a method for replacing a high-altitude vertical corrugated compensator. Background technique [0002] The corrugated compensator is an important equipment and facility for environmental protection and dust removal in the metallurgical plant area. At present, the maintenance and replacement of the corrugated compensator has the following problems: First, it is at a high altitude and it is difficult to hoist. Due to the high installation position of the vertical corrugated compensator and the pipeline, it is difficult to replace it at high altitude, and it is impossible to directly use lifting tools to directly lift and replace it in place, and there are great difficulties in the process of hoisting, dismantling and installation. Second, there is no maintenance platform. During the repl...
