Abstract

The invention discloses a correcting device for correcting the shape of the opening of a conveying pipe and belongs to the technical field of abutting joint of pipelines. The correcting device comprises a sleeve and at least one group of jackscrews, wherein a plurality of mounting holes are formed in the surface of the sleeve; each group of jackscrews comprise at least three jackscrews; each jackscrew in each group of jackscrews corresponds to one mounting hole; each jackscrew is in threaded connection with the corresponding mounting hole and is arranged in the radial direction of the sleeve; one end of each jackscrew is used for making contact with the opening of the conveying pipe. By rotating each jackscrew, the positions of the jackscrew and the sleeve can be adjusted, so that the length of each jackscrew positioned between the sleeve and the conveying pipe can be changed, the opening of the conveying pipe is applied with pressure by the jackscrew, and the shape of the opening of the conveying pipe is corrected; therefore, the correcting device is capable of correcting the opening of the conveying pipe by just rotating the jackscrews, short in correction time, convenient and rapid to use and high in work efficiency.

Description

technical field [0001] The invention relates to the technical field of pipeline butt jointing, in particular to a correction device for correcting the shape of the mouth of a delivery pipe. Background technique [0002] Long-distance pipeline is a tool for long-distance transportation of oil, natural gas and other liquid gases; long-distance pipeline is formed by welding multi-section pipelines. When welding two-section pipelines, it is necessary to align the nozzles of the two-section pipelines. After the nozzles are aligned, weld the nozzles of the two delivery pipes together. The nozzle of the conveying pipe is easily deformed, and the deformed nozzle cannot be aligned with the nozzles of other conveying pipes, and the deformed nozzle needs to be corrected. [0003] At present, multiple jacks are usually used to correct the deformed nozzle, specifically: multiple jacks are fixedly arranged around the deformed nozzle of the conveying pipe, and then the deformed nozzle is ...
