Detailed Description
Examples
As shown in fig. 1 and 2, the pneumatic power-assisted pipe wrench comprises a handle 2 with a wrench seat 8 at one end; the clamp seat 8 is connected with the clamp tongue 1 by a movable pair; an adjusting nut 3 is arranged between the clamp tongue 1 and the clamp seat 8; the adjusting nut 3 and the clamp seat 8 are provided with a rotary pair, the rotary pair is matched with the clamp tongue 1 through a screw hole and a screw thread, and the axis of the screw hole is parallel or collinear with the moving direction of the movable pair.
Wherein, the clamp seat 8 and the clamp tongue 1 are used for adjusting and clamping a pipeline needing to be twisted through the adjusting nut 3;
the other end of the handle 2 is hinged with the cylinder 5;
the cylinder 5 is fixed on a wall or a partition board in a detachable connection mode, and controls the expansion and contraction of the piston rod 4 through a two-position three-way manual reversing valve 6;
the extension and retraction direction of the piston rod 4 is matched with the torsion direction of the pipeline to be twisted.
According to the utility model, the two-position three-way manual reversing valve 6 is adopted to control the expansion and contraction of the piston rod 4 of the air cylinder 5, and the piston rod 4 stretches out and pushes the handle 2 to rotate when being subjected to air pressure, so that the manual force applied to the handle 2 is replaced, the force load of operators is reduced, and the risk of harm to the operators is reduced.
The air cylinder 5 is connected with the handle 2 by using hinge connection, so that the bending motion of the wrist of a person can be achieved, and the pipe rotating operation can be more attached.
In some embodiments, the handle 2 is connected to an end of the piston rod 4 located outside the cylinder 5.
