Abstract
Description
Technical Field
[0001] The utility model relates to a clamp, in particular to a multifunctional pipeline welding clamp. Background Art
[0002] With the development of science and technology and society, PE pipes are widely used as gas pipes and water pipes. During the pipeline laying process, PE pipes often need to be electrofusion welded. During electrofusion welding, the two sections of PE pipe need to remain relatively fixed to ensure welding quality. Currently, pipe clamps are commonly used in this field to clamp and fix two sections of PE pipe. However, existing pipe clamps only have two pipe clamps, which clamp the two sections of PE pipe respectively. The single pipe clamp structure cannot well fix the part of the PE pipe to be welded (the positions on both sides of the electrofusion sleeve). The quality of the electrofusion welding is easily affected by external stress inside the electrofusion sleeve. In addition, existing pipe clamps use a fixed angle setting method for welding and fixing elbows with a certain angle, and cannot be flexibly adjusted according to different angles, resulting in poor applicability.
