Description

Technical Field

[0001] The utility model relates to the field of pipeline installation, in particular to a pipeline hoisting device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is a precious resource indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging, and regulate and distribute water to meet the needs of residents for water resources in life and production. The laying of pipelines is one of the water conservancy construction projects.

[0003] When laying pipelines, they need to be fixed and transported. The traditional way to fix pipelines is to tie and fix the outside of the pipelines with ropes. However, rope fixing not only easily scratches the surface of the pipeline, but also easily causes the pipeline to slip and fall off. Therefore, a pipeline lifting device for water conservancy projects is proposed to solve the above problems. Utility Model Content
