Up-down pipe rod device of vertical catwalk for workover treatment and use method thereof

Abstract

The invention relates to the technical field of petroleum workover auxiliary equipment, and particularly discloses an up-down pipe rod device of a vertical catwalk for workover treatment. The up-down pipe rod device comprises the vertical catwalk and the up-down pipe rod device, the up-down pipe rod device is provided with a support structure, the support structure is divided into a lower support and an upper support, a swing cylinder is fixedly arranged at the top of the upper support, and an overturning arm is mounted outside the swinging cylinder; and the overturning arm is connected with the swing cylinder through a flange plate at the bottom and further provided with an oil cylinder base of a hollow structure, the bottom of the oil cylinder base is fixedly connected with the flange plate, an oil cylinder is arranged in the oil cylinder base, a piston rod is arranged outside the oil cylinder, the piston rod is connected with a movable clamping claw, and a fixed clamping claw matched with the movable clamping claw is fixedly mounted on the outer surface of the opening of the oil cylinder base. An oil pipe and a sucker rod are overturned to the vertical catwalk from a pipe arranging frame, catwalk connection is not needed, the vertical position of the pipe rod can be controlled, and the tumbling condition does not exist.

Description

technical field [0001] The invention relates to the technical field of petroleum workover auxiliary equipment, in particular to an upper and lower pipe rod device and a use method of a vertical catwalk for well workover operations. Background technique [0002] In oil workover operations, the power catwalk is generally used to transport the tubing and sucker rods to the wellhead, and then the pipes and rods are lifted and lowered. Power catwalks are generally divided into fixed catwalks and lifting catwalks. The fixed catwalk is manually transported to the catwalk by pipe poles. The fixed catwalk has a low degree of automation and the labor intensity of the workers is high. Lifting catwalks generally adopt a patent similar to that disclosed in CN201420302488. An upper and lower pipe rod mechanism, also known as a pipe pulling device, raises the pipe rod, and the pipe rod relies on its own gravity to move from a high place to a low place and roll down. To the catwalk, the c...

Then, the lifting arm oil cylinder 13 acts to drive the lifting arm 5 to rotate around the lifting arm hinge shaft 20, and the manipulator on the lifting arm 5 clamps the oil pipe or the sucker rod to directly rotate from the horizontal state to the vertical state; , stop the action by the lifting arm cylinder 13, combined with the function of the limit device 24, to ensure that the lifting arm 5 will not continue to turn over when it is in the vertical state, and realize the delivery of the oil pipe or sucker rod". In actual use, it must be Considering the specifications of oil pipes or sucker rods, the clamping manipulator of this patent has too many specifications, and the replacement is too troublesome. It is inconvenient to operate when using oil pipes or sucker rods of various specifications
