In order to facilitate the transportation and exploitation of oil, it is usually necessary to construct a large number of chemical pipelines to transport natural gas or oil. When constructing petrochemical pipelines, it is usually necessary to use lifting devices to move the pipeline position to facilitate the installation of the pipeline.

[0004] With the above technical solution, the lifting device is first installed on both ends of the pipe to be dropped, and then the hook of the crane is hung on the lifting ring, so the pipe can be directly lifted without stopping the crane and waiting for the installation of the sling, and the lifting efficiency is high. However, with the above technical solution, the pipe lifting device needs to be used in conjunction with a crane or a hoist when in use. Since the crane and the hoist need to be fixed with a positioning device to maintain balance, they can only perform simple lifting functions and cannot drive the petrochemical construction pipeline to move long distances as needed.

[0005] To this end, we propose a pipeline lifting device for petrochemical construction to solve the above problems. Utility Model Content
