Ship pipeline lifting type conductive roller carrier

Abstract

The invention discloses a ship pipeline lifting type conductive roller carrier. The ship pipeline lifting type conductive roller carrier comprises a metal bottom plate, an outer stand column casing pipe, an inner stand column pipe, a telescopic spring, a spring jacking rod, a roller bracket, a roller shaft and a roller shaft sleeve, wherein the outer stand column casing pipe is perpendicularly welded to the metal bottom plate; the inner stand column pipe is partially arranged in the outer stand column casing pipe and fixed; the spring jacking rod is partially arranged in the inner stand columnpipe; the telescopic spring is arranged between the spring jacking rod and the inner stand column pipe; the roller bracket is fixedly installed at the top of the spring jacking rod; the roller shaftsleeve is fixedly installed on the roller bracket; the roller shaft and the roller shaft sleeve are installed in a matched mode and arranged on the roller bracket; and round nuts are installed at thetwo ends of the roller shaft. According to the ship pipeline lifting type conductive roller carrier, the construction quality problems of pits and the like caused by electricity touch during direct construction on a roller by a traditional pipe are solved, and the product quality and the working efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a ship pipeline lifting type conductive roller frame. Background technique [0002] In the process of ship construction, the workload of ship management accounts for 15%-20% of the workload of the whole ship, so the position of ship pipeline installation and construction is very important in the construction process. Steel butt pipes are an integral part of every boat. According to the investigation of the current situation, there is work to close the pipes in the stages of pre-installation in sections, general assembly of the platform, and loading in the dock. Therefore, in the process of pipeline manufacturing, the quality control of pipelines is particularly important. When the closed pipe is made, flanges need to be welded at both ends of the pipeline. The existing method is to directly weld the flanges directly on the pulley frame, and weld while rotating....

AI Technical Summary

Problems solved by technology

When welding, the surface of the pipe is in contact with the pulley frame for conduction. Because there is floating rust on the surface of the pipe, the grounding of the pipe on the pulley frame is poor, so that after the pipe touches the pulley, the outer surface of the pipe is uneven, which has a great impact on the manufacturing quality. influences
