Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the explanatory text.

[0025] like figure 1 , 2 As shown, an electromagnetic pipe welding counterpart includes an upper annular cage 1 and a lower annular cage 3 hinged up and down; the end of the upper annular cage 1 away from the hinge is connected to the upper end 19 through a latch 4; The end of the frame 3 away from the hinge is connected to the lower end 20 through the latch 4; the upper annular cage 1, the lower annular cage 3, the upper end 19 and the lower end 20 form a ring frame as a whole; the outer side of the ring frame is provided with three support frames 9; The three supporting frames 9 divide the ring frame into three sections; the ring frame is a hollow structure as a whole.

[0026] The inner top of the support frame 9 is provided with a hydraulic cylinder 12; the bottom ...

Abstract

The invention discloses an electromagnetic type pipeline welding aligning device and a working method. The method comprises the following steps that rough aligning is carried out on pipelines needingto be in butt joint; the aligning device is arranged at a connector of the pipelines, a line laser measuring instrument is aligned with a welding seam at the connector, and two laser displacement sensors are distributed on the two sides of the welding seam; a hydraulic cylinder is adjusted according to the diameter of the pipelines; the hydraulic cylinder drives a base plate, an adjusting column and an aligning device pressing plate to downwards extrude, and the pipelines are fixed; and after the pipelines are fixed, whether the centering effect and the width of the welding seam meet the needed standard or not is checked through the laser displacement sensors and the line laser measuring instrument. According to the electromagnetic type pipeline welding aligning device and the working method, the two laser displacement sensors are arranged on an annular holder in parallel, the coaxiality problem of the pipelines is detected through the distances between the sensors and the surfaces ofthe two pipelines, and if the two measured distances are the same or within the error range, centering is completed, the aligning precision is high, and operation is convenient.

Description

technical field [0001] The invention relates to the field of welding devices, in particular to an electromagnetic pipe welding counterpart and a working method. Background technique [0002] At present, in the country, the transportation method of liquid and gas materials transported by enterprises is mainly pipeline transportation. It is also a transportation method that specifically transports petroleum, coal and chemical products from the production site to the market. It is a special part of the trunk transportation in the unified transportation network. Pipeline Transportation has the advantages of large volume, less permanent land occupation, short construction period, less investment, low energy consumption, low freight, good benefits, less affected by harsh weather conditions, safe and reliable, long-term stable operation, no noise along the way, less pollution, Can better meet the characteristics of green logistics. Therefore, the manufacture and production of high...
