The heavy caliber pipeline has a staggered opening problem because of the heavy weight of a single piece and the inevitable extrusion deformation of the heavy caliber pipeline in the transportation process. The traditional construction process usually adopts a spot welding fixture at the position of a pipe orifice, and then the opening is aligned through the adjustment of a wedge. Although the method is simple to operate, the welding and cutting operation on the surface of the base metal is easy to influence the chemical composition and the mechanical property of the base metal and damage the anticorrosive coating on the surface of the pipeline, and in addition, the problems of large consumption of auxiliary materials, serious waste, low working efficiency and the like exist during long-distance pipeline construction. The pipeline aligning device is applied, at present, the pipeline aligning device at home and abroad is mainly divided into an inner aligning device and an outer aligning device, the aligning precision of the inner aligning device is high, but the manufacturing cost is high, and the pipeline aligning device is suitable for long-distance pipeline construction; the outer aligning device is divided into a fixed diameter aligning device and a chain type aligning device, the fixed diameter aligning device is only suitable for aligning construction operation of pipelines with the same pipe diameter, and the chain type aligning device can be applied to aligning of pipelines with different pipe diameters, but does not have a better solution to the problem of local dislocation of the pipe orifice.

The existing patent document with publication number CN111037202A provides a large-diameter pipeline aligning device and an operation method, the device can realize quick and accurate aligning, effectively adjust the misalignment problem, is simple to operate, is easy to operate, improves the operation efficiency, has simple composition units, can be manufactured on site according to the construction conditions, is suitable for aligning operation of large-diameter pipelines with different pipe diameters, can be repeatedly used for a plurality of times by one-time manufacturing, and saves the construction cost. Although the device has more beneficial effects, the following problems still exist: the device need adjust preliminary location to the pipeline with the help of outside instrument when using, just can carry out accurate alignment after preliminary adjustment again, effectively adjusts the wrong limit problem. In view of this, we propose a large-caliber pipe aligning device.
