[0002] The global oil and gas industry is marching towards the ocean. The vast ocean oil and gas resources have become the focus of competition in the global oil industry today and in the future. Marine oil pipes are increasingly valued by the industry because of their key role in all aspects of oil extraction. According to material classification, marine pipelines are mainly divided into two categories: steel pipes and flexible pipes, among which flexible pipes are made of metal and polymer composites. Compared with steel pipes, flexible pipes are easy to bend, easy to lay, recyclable, more economical, and more suitable for marine environments. The existing laying of flexible pipes is to clamp the flexible pipe straight through a clamping device, and then clamp the flexible pipe downward and continue to send it out. However, the diameter of the wellbore drilled for oil extraction is small, and the clamping device of the flexible pipe is heavy, which is not convenient to move. At present, the operation of aligning the flexible pipe working head with the wellbore is also inconvenient. Therefore, a device that can easily adjust the position of the flexible pipe working head is needed. Summary of the invention
