Background
The biggest and most heavy workload of operators in the well repairing process is the screwing of an oil pipe lifting tool, an oil discharging tool and a drilling tool, and in the past, pipe tongs or chain tongs have been used, so that the labor intensity is high and the danger is caused. The hydraulic power tongs are mechanical screwing-off tools operated by the workover rig power, so that the labor intensity of workover workers can be greatly reduced, and the occurrence of injury accidents can be avoided or reduced. Meanwhile, the hydraulic power tongs strengthen the torsion of threads of the pipe tool and the drilling tool, and reduce the occurrence of tripping accidents of the pipe tool and the drilling tool. The working principle of the hydraulic power tongs is that the power of the workover rig is transmitted to a hydraulic motor of the hydraulic power tongs through a travel speed reducer, and then the hydraulic motor is subjected to two-stage or one-stage speed reduction, so that a split gear of a tong head rotates to generate high and low rotating speeds, and a pipe tool (drilling tool) is driven to rotate. When the opening gear rotates, the plate frame does not rotate under the braking action of the braking hammer, so that the opening gear and the jaw plate frame have relative movement. Thus, the two rollers of the jaw plate climb on the ramp plate and force the jaws of the crotch plate to move toward the center of the pipe tool until they bite into the pipe tool, and then rotate the pipe tool with the opening gear.
