The main working procedure of the minor repair operation of the oil field is to lift and put the sucker rod and various oil pipes. When the traditional minor repair operation is used for lowering an oil pipe into a well, the front end of the oil pipe needs to be lifted to an oil pipe stool manually and lifted by a lifting clamp. When the oil pipe is lifted from the well, the oil pipe needs to be manually pushed away from the well mouth and placed on an oil pipe stool. However, the operation site is often muddy and slippery, and particularly in winter, the operators often have accidents of slipping, colliding, clamping, hitting and the like, and a great safety risk exists. In order to reduce the labor intensity of workers and improve the operation safety, at present, a pipe rod conveyor is used in each large oil field to replace manual operation.
However, the applicant has found that the pipe conveyor used in each large oil field at present has at least the following defects: (1) most of pipe rod conveyors do not have the conveying function of the sucker rods, and the manual operation is still used, so that the labor and the labor are wasted when the sucker rods are dragged to the pipe racks; (2) the pipe rod conveyor mostly uses a V-shaped chute, and when a pipe column is lifted or lowered, the pipe column slides with the chute, so that the thread of the pipe column is easy to wear; (3) in the lifting process of the pipe column, the angle between the pipe column and a conveyor chute is constantly changed between 0 and 90 degrees along with the lifting of a traveling block hook, but the pipe column cannot be clamped by a common pipe rod conveyor at present and is changed along with the angle; (4) the pipe rod conveyor is mostly lifted by adopting a four-bar linkage mechanism or a scissor fork mechanism, and the lifting action and the advancing action cannot be synchronous, so that the operation time is long and the efficiency is low; (5) the pipe rod conveyor has large external dimension, large occupied space and high transportation cost, and is not beneficial to placing well site pipe columns and transferring and carrying equipment.
