Multi-degree-of-freedom regulation device and spraying system

Abstract

The invention relates to a multi-degree-of-freedom regulation device and a spraying system. The multi-degree-of-freedom regulation device comprises a mounting mechanism and a rotary frame mounting seat; the mounting mechanism comprises a drive cylinder, a positioning control valve, a drive cylinder fixing seat and a connection component; the end part of a piston rod of the drive cylinder is fixedly connected with a component to be regulated; the drive cylinder fixing seat is arranged on the connection component in a sliding manner and can slip in a stretching or shortening direction of the piston rod relative to the connection component; the rotary frame mounting seat comprises a connection plate and a plurality of fixed blocks; the connection plate is connected with the connection component in the sliding manner and can slip relative to the connection component; and a plurality of fixed blocks are fixedly connected with the connection plate and are fixed on a mounting component. The spraying system comprises a powder spraying chamber, spraying equipment and the multi-degree-of-freedom regulation device. By adopting the spraying system, accurate positioning of a pipe wall distancebetween the powder spraying chamber and a pipeline is realized, and the uniformity of an FBE coating during pipeline anticorrosion and mending construction is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of pipe repairing, in particular to a multi-degree-of-freedom adjusting device and a spraying system. Background technique [0002] At present, in the construction of marine pipelines, after pipeline welding and sand blasting and rust removal, the welded joints of the pipe ends are repaired. Among them, the coating formed by FBE (Fused Bonded Epoxy Resin) has excellent anti-corrosion performance, which is compatible with the current mainstream main pipeline coatings (FBE, 3LPE (three-layer polyethylene coating), 3LPP (three-layer polypropylene coating) Layer)) Compatibility is better. The construction technology of foreign FBE pipeline anticorrosion patch is relatively mature, and its application is also relatively wide. The domestic FBE automatic coating equipment has been successfully developed for the construction of marine pipelines. [0003] The automatic coating equipment in the prior art cannot quickly an...

Problems solved by technology

[0004] This application provides a multi-degree-of-freedom adjustment device and a spraying system, which solves or partially solves the problem that the automatic coating equipment in the prior art cannot quickly and accurately adjust the relative position with the pipeline, and then cannot ensure the FBE coating during pipeline anti-corrosion joint construction. The technical problem of uniformity
