Description

Technical Field

[0001] The utility model relates to the field of pipeline construction, in particular to a PE pipeline splicing auxiliary supporting device. Background Art

[0002] PE pipes are non-toxic, have no scale layer, and are not easy to breed bacteria. As municipal water supply pipes, they will not cause secondary pollution to urban drinking water. This is a huge advantage that traditional steel water pipes cannot match. As water supply mains in cities require a large water supply, PE pipes with a diameter of 1200 mm are generally used for laying.

[0003] In order to facilitate the transportation of PE pipes from the factory to the construction site, PE pipes are generally cut into multiple sections of the same length for loading and transportation; during the installation, a crane is required to lift the PE pipes to be installed and splice them close to the installed PE pipes;

[0004] However, during the process of splicing the pipelines, the operator needs to operate the crane to lift the pipeline to be installed and move it for fine-tuning so that the two sections of the pipeline can be aligned. During the alignment process, the crane needs to be operated to move the pipeline for multiple alignments. Due to the large size of the crane itself, the movement range of its swing arm is large, which places high technical requirements on the operator and reduces the construction efficiency.
