Abstract

The invention relates to a large-pipe-diameter shell section pair group extension device which comprises a shell section three-dimensional adjustment device and at least two groups of conveying roll wheel frames, wherein the conveying roll wheel frames and the shell section three-dimensional adjustment device are arranged on the same straight line side by side. The shell section three-dimensional adjustment device comprises a conveying roll frame, a first roll wheel frame and a second roll wheel frame which are arranged on a bottom layer guide rail, the conveying roll frame is arranged between the first roll wheel frame and the second roll wheel frame, and shell sections arranged between bottom layer rails axially move an oil cylinder to drive the second roll wheel frame to be adjusted. The large-pipe-diameter shell section pair group extension device is simple in structure, high in reliability, low in processing difficulty compared with like products, little in material use quantity, low in cost and the like.

Description

technical field [0001] The invention relates to a pipeline prefabrication processing equipment, specifically a butt joint length device for a large-diameter cylinder section group, and belongs to the technical field of marine engineering equipment manufacturing. Background technique [0002] In the prefabrication production process of large-diameter pipelines, when multi-tube joints are assembled, the butt joint length device not only needs a three-dimensional adjustment function, but also requires a longer-distance conveying system, which has low production efficiency, complex construction technology, and long production cycle. specialty. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a large-diameter cylinder section group butt joint length device, which can conveniently carry out three-dimensional adjustment and pairing of two cylinder sections, and at the same ...
