[0002] Pipeline arc surface operation refers to the work that needs to be carried out on the pipeline arc surface during pipeline construction, maintenance or inspection. Since the pipeline arc surface is usually in a high or narrow position and there is a risk of falling, it is necessary to use a personnel anti-falling device. At the same time, when carrying out pipeline arc surface operation, relevant safety specifications and operating procedures must be strictly observed to ensure that the operating personnel are equipped with and correctly use the personnel anti-falling device, and the device needs to be regularly inspected and maintained to ensure its normal operation and reliability, so as to effectively reduce the accidental risks in pipeline operation and protect the safety of operating personnel.

[0003] However, during the use of traditional personnel anti-falling devices for pipeline arc surface operation, it is usually necessary to weld columns at the pipeline base material to hang the safety belt on them. After the operation is completed, processes such as cutting the welded part, repairing welding, grinding, and anti-corrosion are required, which makes the installation of the safety belt hanging point and the subsequent processes rather cumbersome. At the same time, when the traditional personnel anti-falling device for pipeline arc surface operation is installed and used, it is usually not easy to adjust the angle of the support rod, so it may not be easy to install or use on pipelines with different diameters, which may bring inconvenience to the long-term work of workers.
