Problems solved by technology

[0004] The purpose of the present invention is to provide a connection and centering device for pipeline engineering in view of the many deficiencies of the prior art. The present invention solves the problem that the existing pipeline centering welding needs different backings in pipelines with different diameters. , each time welding, the backing needs to be found again and adjusted several times to achieve the problem of alignment

Abstract

The invention discloses a connecting centering device for pipeline engineering. The connecting centering device comprises a supporting frame, the supporting frame is provided with a working platform,the working platform is provided with first fixing mechanisms, a second fixing mechanism and a sliding groove, the first fixing mechanisms are uniformly arranged, the bottom of the first fixing mechanism is connected with the sliding groove, the sliding groove is connected with the working platform, each first fixing mechanism comprises sliding blocks and positioning rings, the sliding blocks areconnected with the positioning rings, first connecting blocks are uniformly arranged in the positioning rings, limiting mechanisms are uniformly arranged on the first connecting blocks, lifting columns are arranged on the working platform, lifting grooves are formed in the lifting columns, and the lifting grooves are connected with the second fixing mechanism. According to the connecting centeringdevice for pipeline engineering, the problem that different supporting pads need to be welded in pipelines with different diameters in existing pipeline pairs, each time of welding, the supporting pads need to be re-found and adjusted for many times to achieve centering are solved.

Description

technical field [0001] In particular, the invention relates to a connection centering device for pipeline engineering. Background technique [0002] With the long-term operation of urban pipelines, structural problems such as damage to pipelines, misalignment and disconnection of pipeline connections have become more and more prominent. If it is not repaired in time, it will inevitably cause serious negative impacts on the environment, economy and society. Excavation restoration is a relatively common restoration method, but this method has disadvantages such as low efficiency, high cost, and large environmental pollution, and excavation restoration will bring greater pressure to urban traffic. Therefore, trenchless repair is increasingly favored for its high efficiency, economy, and low environmental impact, and has become a new means of pipeline repair. [0003] When the pipeline is in use, when the designed pipeline length is too long, multiple pipelines need to be weld...
