Using machinery instead of manpower for oil pipe handling is an effective way to improve the working environment of workers and ensure safe production.

At present, in the workover operation process, more hydraulic transmission machinery is used to carry the oil pipe at the wellhead. For example, the Chinese patent "oil pipe hydraulic lifting device and method of use" with the publication number CN104278956A discloses a oil pipe hydraulic lifting device to Solve the oil pipe handling work in the workover construction process. The device is mainly composed of the body, hydraulic system, and control system. It is characterized in that the lifting of the oil pipe is completed through the cooperation of a group of lifting cylinders. The shortcomings of small lateral movement range, slow lifting process and easy damage to the lifting cylinder; non-patent literature "A New Oil Pipe Lifting Delivery Device" (Li Guohua, "Xinjiang Petroleum Science and Technology", Vol. 23, No. 1, 2013, No. Page 40) discloses a new type of oil pipe lifting and delivery device, which is mainly composed of a support base and a movable oil pipe bearing plate. However, there is a big limitation on the lifting height of the bearing plate, and it also has the disadvantage of small lateral movement.
