Problems solved by technology

When operating the hydraulic tongs, the operator needs to stand at the tail or the left and right sides of the hydraulic tongs. Due to the different degrees of tightness of the threaded threads of the pipe string, the reverse torque of the hydraulic tongs will cause the hydraulic tongs to go up and unfasten in the opposite direction. Anti-torque, the tail rope of the clamp will be broken when it cannot bear the huge pulling force, which will inevitably cause injury to the operator
The second is that the operator of the hydraulic tongs has to stand for a long time and repeat the same action frequently, which is labor-intensive.

Abstract

The invention provides a remote control type hydraulic clamp device and a control method, and belongs to the technical field of down-hole operation machinery of oil fields. A telescopic pushing hydraulic cylinder is integrally mounted in a cross beam of a height adjusting bracket; a reaction torque device is connected with the height adjusting bracket through a dovetail-groove-shaped connecting bolt and connected with a hydraulic clamp through a bolt; a hydraulic clamp high-low speed gear-shifting control device, a hydraulic clamp positive-reverse rotation control device and a hydraulic main clamp positive-reverse rotation control device are integrally mounted the body of the hydraulic clamp; an automatic gear engaging valve switching system is connected with a hydraulic pipeline solenoid-controlled valve of a control system through oil inlet / outlet pipelines; a safety gate control device, a hydraulic line control combined valve, a motion switch solenoid-controlled valve, and a main hydraulic line solenoid-controlled valve are mounted on the body of the hydraulic clamp; an infrared detection device is mounted on the reaction torque device; and a control line and a hydraulic line are integrated in the height adjusting bracket. The remote control type hydraulic clamp device is simple in structure, easy to manufacture, convenient to use, low in processing cost and extremely easy to popularize and use.

Description

technical field [0001] The invention relates to a remote-controlled hydraulic tong device and a control method, belonging to the technical field of downhole operation machinery in oil fields. Background technique [0002] Downhole operations are mainly engaged in oil field overhaul, oil testing, maintenance, and measure operations. In order to reduce the labor intensity of workers, hydraulic tongs are equipped, which changes the working method of making up and breaking out with pipe tongs, and greatly reduces the labor intensity of wellhead operators. . Generally adopt the steel wire rope to hang it at the wellhead at present, the tong tail rope is fixed on the derrick thigh, and the mode of manual control operation. When operating the hydraulic tongs, the operator needs to stand at the tail or the left and right sides of the hydraulic tongs. Due to the different degrees of tightness of the threaded threads of the pipe string, the reverse torque of the hydraulic tongs will ...
