A kind of insulating scissors for high-voltage wires that is close to anti-skid and uses torsion springs to store energy and save labor

Abstract

The invention discloses a close-attaching, anti-slip, torsional spring accumulating force using, and labor-saving insulation cutter for a high-voltage line. A structure of the cutter includes a firstplier handle, a second plier handle, a plier head labor-saving device, and an anti-clamp block. The second plier handle is mounted on the left side of the first plier handle; one end of the first plier handle is connected to the plier head labor-saving device; the plier head labor-saving device is connected to the second plier handle by an adhesion manner; and the anti-clamp block is mounted on the outer surface of the plier head labor-saving device and is fixedly connected by a welding manner. Through fit sliding of a gap between a sliding groove track and a limit sliding block, an upper plier piece and a lower plier piece are allowed to fit together, the insulating cutter is prevented from aging to produce the gap to slip, the force of a cam block to a torsional spring is utilized, so that a heat dissipation friction pad is in contact with and separated from a sleeve, force accumulating and force releasing are separately performed, the shear reactive force and the operating strengthof an operator are reduced, shearing is fast performed, smoothness of a shearing surface is ensured, and the usage effect of high-voltage lines is not affected.

Description

technical field [0001] The invention relates to the field of insulating shears for high-voltage wires, more precisely, it relates to an insulating shears for high-voltage wires that is close to anti-skid and uses torsion springs to store force and save labor. Background technique [0002] High-voltage wires are used to transmit high voltage over long distances. The internal conductors require a certain strength and cost considerations. The current high-voltage wires are mostly aluminum wires, with a steel wire inserted in the middle. Under the modern development trend, remote areas are gradually Power on, and in the process of power on, most of the high-voltage lines are manually cut. The existing traditional technology is not comprehensive, and has the following disadvantages: [0003] Because the high-voltage wire has a structure of copper core and aluminum sheath, the force used to cut the high-voltage wire is getting bigger and bigger. However, due to the long use time o...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a kind of high-voltage line insulating shears that are close to the anti-skid and use torsion springs to store energy and save energy, so as to solve the problem in the prior art that the high-voltage lines are copper-cored and aluminum-sheathed, so that when cutting the high-voltage lines , the force used is getting bigger and bigger, and because the insulating cutter is used for too long, it is easy to make the two movable pliers not fit tightly enough, and there is a certain gap, which will cause the pliers to slip and cause the pliers to cause damage to the conductor. Scratches and excessive force not only increase the labor intensity of the operator, but also easily cause the high-voltage line to have a large inertial force, which will hurt the operator when the line is broken
