Abstract

The invention provides a pipeline roundness adjusting device. According to the device, one end of a first supporting rod is hinged to one end of a second supporting rod, the other end of the first supporting rod is hinged to one end of a first center hinge seat, the other end of the first center hinge seat is hinged to one end of the other first supporting rod, the other end of the other first supporting rod is hinged to one end of the other second supporting rod, the other end of the second supporting rod is hinged to one end of a second center hinge seat, the other end of the second center hinge seat is hinged to the other end of the other second supporting rod, two ends of a tightening structure penetrate through the center of the first center hinge seat and the center of the second center hinge seat, and the first center hinge seat and the second center hinge seat are separately and movably connected to the tightening structure in a sleeved mode in the direction close to each other. The device is simple in structure and convenient to use.

Description

technical field [0001] The present application relates to the field of pipeline construction, in particular to a pipeline roundness adjustment device. Background technique [0002] In industrial production, large-diameter pipes will be severely deformed due to their own weight and the steel plate rolling process after they are manufactured. Usually, the manufacturing process is to add temporary supports inside and weld them to the inner wall of the pipe. The welding process also requires constant adjustment of the pipe. If the diameter reaches the requirement, then add the next support. The operation is cumbersome and the material waste is serious. Contents of the invention [0003] One of the purposes of the present application is to provide a pipe roundness adjustment device, aiming to improve the existing problem of easy deformation of large-diameter pipes. [0004] The technical scheme of the application is: [0005] A pipe roundness adjustment device, comprising two...
