Abstract

The invention relates to the field of pipeline installation, in particular to a portable large pipeline welding butting device. The device is characterized by comprising an annular retainer, pressingplates and locking bolts, wherein the annular retainer sleeves a butting seam of the two pipelines, a plurality of pressing plates are arranged and are uniformly arranged on the inner side of the annular retainer, the inner side surfaces of the pressing plates abut against outer walls of the two pipelines respectively, the outer sides of the pressing plates are provided with the locking bolts; thelocking bolts pass through the annular retainer and are connected with the annular retainer through threaded through holes; the pressing plates abut against the outer walls of the pipelines by rotating the locking bolts. The butting device is applied to the welding butting construction of a large pipeline, the butting device is fixed on the outer side of the pipeline, and unfitness of butt jointof the pipelined is effectively reduced by adjusting the pressing plates which are arranged around the butt joint of the pipelines. The device is simple in operation and convenient to manufacture, construction resources and pipeline adjustment time are effectively reduced.

Description

technical field [0001] The invention relates to the field of pipeline installation, in particular to a portable large-scale pipeline welding counterpart device and a usage method. Background technique [0002] For the on-site welding during the installation of large-scale pipelines, due to the errors of the pipeline itself, such as manufacturing errors and transportation deformations, the amount of misalignment of the pipelines during welding often exceeds the standard, which seriously affects the quality of pipeline welding. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provide a counterpart device for controlling the pairing of pipelines during welding and a method of use thereof. [0004] In order to achieve the above object, the present invention is achieved in that: [0005] A convenient large-scale pipeline welding counterpart device, including an annular cage, a pressure plate and a locking bo...
