The invention discloses a self-clamping type circular tube spanner capable of displaying a torque and an operation method thereof. The self-clamping type circular tube spanner capable of displaying the torque is mainly characterized in that the upper part of the front end of a spanner body is provided with a lead screw; a clamp plate with a thread opening and a skidding clamp splice are arranged through the lead screw; the clamp plate and the skidding clamp splice form a spanner nip with an adjustable caliber size; the spanner body is provided with a movable pillar and a pressure sensor; the pressure sensor is connected with a pressure indicating instrument; and the skidding clamp splice is enabled to slide leftwards through a four-bar mechanism below the movable pillar to stably clamp a tube. The self-clamping type circular tube spanner disclosed by the invention is a twisting tool which not only is not capable of destroying the surface of the tube but also is capable of displaying the torque, and is more convenient in use.
Description
technical field [0001] The present invention relates to screwing tools. Background technique [0002] Pipe wrench is used to tighten the threaded connection of round pipes in all walks of life, but the use of pipe wrench will often damage the surface of the pipe, and the tightening torque cannot be measured. In actual production, some industries require that when the round pipe is tightened, it is necessary not to damage the surface of the pipe, but also to know exactly how much torque has been tightened. [0003] For example, when tightening the packing of the pumping unit in the oil field, the torque is large, and the packing is too tight, which will increase the friction, and the friction block of the packing drives the motor, which consumes the most power. Oil leakage requires an optimal tightening torque. Therefore, it is necessary to develop a screwing tool that does not damage the surface of the pipe and can display the torque. This requires the development of a new ...
