Abstract

The invention provides a pipe column screwing-on and screwing-off device, a sucker rod wrench square clamping mechanism and a coupling clamping mechanism. The pipe column screwing-on and screwing-off device comprises a main clamp body, a back clamp body and at least one supporting assembly; the main clamp body is provided with at least one main clamp installation lug base; the back clamp body is provided with at least one back clamp installation lug base; and each supporting assembly comprises an installation base, a supporting rod, a sleeving piece and an adjusting hoop, wherein the bottom of the supporting rod is connected with the installation base, the main clamp installation lug base, the adjusting hoop, the sleeving piece and the back clamp installation lug base are sequentially arranged on the supporting rod in an abutting and sleeving manner, and the supporting assembly is suitable for adjusting the distance between the main clamp body and a back clamp by replacing the adjusting hoops of different thicknesses. According to the pipe column screwing-on and screwing-off device, the distance between a main clamp and the back clamp can be actively adjusted by replacing the adjusting hoops of different thicknesses, the universality of the pipe column screwing-on and screwing-off device is improved, and the pipe column screwing-on and screwing-off device can be suitable for pipe columns of different types and different specifications such as sucker rods and oil pipes.

Description

technical field [0001] The invention relates to the field of oil field workover operation equipment, in particular to a pipe string up and breakout device, a sucker rod wrench square clamping mechanism and a collar clamping mechanism. Background technique [0002] In oilfield workover operations, threaded pipe string components such as unloading pipes and sucker rods are generally installed through hydraulic tongs. Commonly used hydraulic tongs are mainly composed of main tongs and back-up tongs. During work, the back-up tongs are responsible for clamping the pipe string, and the main tongs are responsible for clamping the pipe string and rotating it clockwise or counterclockwise, thereby realizing the make-up and break-out of the pipe string. [0003] Since the oil pipe and the sucker rod are quite different in structural form and external dimension, the clamping positions of the main tong and the backup tong are different during make-up and break-out operations. When maki...
