Problems solved by technology

The traditional factory matching method generally adopts the manual matching method, using chain hoists, hammers, self-made backers, and wedge-shaped tools for matching. This method is less effective and consumes more manpower; High, when the rolled pipe has a "heart mouth", it will greatly increase the difficulty of assembly and reduce work efficiency; the third is that the quality of the alignment cannot be guaranteed

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0023] Such as Figure 1-7 As shown, the present embodiment relates to a large-diameter pipe matching device. Specifically, the matching device includes a square frame 1 and a pipe coupler arranged in the square frame 1. The pipe coupler includes two oppositely arranged clamps. block 2; a jack 3 is arranged between each clamping block 2 and the square frame 1 (that is, a jack 3 is fixed on the square frame 1 on the side of the pipeline coupler 2, and the two jacks 3 can drive two clamping blocks 2 Slide towards each other or slide against each other so that the two clamping blocks 2 are clamped or separated from each other, and the opposite sides of the two clamping blocks 2 have an arc surface, and the above-mentioned jack 3 drives the two clamping blocks 2 to slide towards each other and mutua...

Abstract

The invention relates to the technical field of pipeline construction, in particular to a counterpart device for a large-diameter pipeline; two relatively arranged clamping blocks are arranged in a square frame; a jack is arranged between each clamping block and the square frame, and the relative sides of the two clamping blocks are provided with arc-shaped surfaces, the jack pushes the two clamping blocks to clamp tightly, so that the arc-shaped surfaces of the two clamping blocks are closed and formed with a clamping cavity for clamping the pipeline; and each clamping block is sequentially provided with a plurality of rollers whose curved surfaces are aligned with the curved surfaces of the arc-shaped surfaces along the curved surface of each arc-shaped surface; during the use, the pipeopenings of the two pipelines to be in counterpart are arranged between the two clamping blocks; and then the jack is used for pushing the two clamping blocks to fold so as to complete the pipeline counterpart, and since the rollers are arranged on the arc-shaped surfaces, the rollers can rotate in a clamping cavity; the pipeline is convenient to weld; and a roller transportation chain is arrangedbehind the counterpart device, so the pipeline counterpart speed can be quickened greatly; and the counterpart quality can be improved.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a large-diameter pipeline matching device. Background technique [0002] The production and installation of large-diameter pipes (above 1000mm in diameter) generally go through several processes of coiling - assembly - welding - production - installation. According to the size of the coiling machine, the length of the coiled pipe is 3 meters, and the pipe group Alignment (alignment) is a link between the preceding and the following. It not only needs to repair the out-of-round nozzle caused by the coiled pipe, but also creates conditions for the next welding process. The quality of the assembly directly affects the quality of the next welding and the shape of the pipe after forming Exterior. The traditional factory matching method generally adopts the manual matching method, using chain hoists, hammers, self-made backers, and wedge-shaped tools for matching. This m...
