At present, the characteristics of the mainstream sucker rod operation process: manual operation, manual make-up and unloading, manual handling and hooking, the entire operation process is mainly manual, the operation intensity is high, and the operation environment is harsh
In addition, during the workover operation, the tubing or sucker rod needs to be lifted and unloaded. At present, the tubing or sucker rod with different diameters are equipped with special-purpose manipulators for grabbing operations. The replacement is cumbersome, which is not conducive to the continuous operation.

Abstract
The invention relates to a pipe-grabbing manipulator for well workover operation and a use method thereof. The technical solution is: the oil cylinder is installed on the fixed frame, and the fixed frame is connected to the mounting plate and the connecting plate; The components are in contact with the horizontal frame and the fixed frame respectively; the middle clamping cylinder is connected to the support frame through the first rotating shaft, and the support frame is installed on the mounting plate and the connecting plate through bolts, and is jointly clamped by the two clamping cylinders and the middle clamping cylinder tight target. The beneficial effect is: not only has the function of loosening and clamping the target body, but also can surround the oil pipe or the sucker rod, so that the oil pipe or the sucker rod can move along the axial direction, and can also rotate along the axial direction, so that the oil pipe or the sucker rod can The sucker rod plays a guiding role; it is suitable for oil pipes or sucker rods, and is suitable for oil pipes or sucker rods of different specifications. It only needs to simply replace one part, and the replacement is simple and uncomplicated.
Description
technical field [0001] The invention relates to a petroleumworkovermanipulator and a method, in particular to a manipulator for workover operation and a use method thereof. Background technique [0002] Workover operations are the most common form of work in oilfields, and can be divided into minor repair operations and major repair operations. Minor repair operations are mainly completed by lifting and lowering operations, and there are major operations such as pump inspection, process change, and sand washing. At present, the characteristics of the mainstream sucker rod operation process are: manual operation, manual making and unloading, manual handling and hooking, the entire operation process is mainly manual, the operation intensity is high, and the operation environment is harsh. In addition, during workover operations, tubing or sucker rods need to be lifted and unloaded. At present, tubing or sucker rods with different diameters are equipped with special-purpose m...
