Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power maintenance, and particularly relates to a power distribution line maintenance wire cutting device. BACKGROUND

[0002] Power maintenance is a series of activities such as inspection, maintenance, repair and testing on equipment and lines in a power system to ensure the safe, stable and reliable operation of the power system. In the process of regular maintenance, line upgrade or fault maintenance, a corresponding wire cutting device is often used.

[0003] The utility model with the authorized publication number CN219464623U discloses a power distribution line maintenance wire cutting device. By setting the feeding structure, when the hydraulic cutter is continuously cutting, the transmission wheels on both sides can drive the electric wire to move through their rotation, thereby adjusting the position of the electric wire for subsequent cutting, so that the staff does not need to touch the circuit to avoid the risk of electric shock. By setting the rotatable fixed plate, the extrusion spring between the fixed plate and the through hole makes the fixed plate tightly contact with the electric wire, thereby fixing the electric wire. At the same time, the electric wire is displaced by its own gravity. The two fixed plates in the shape of "8" can prevent the electric wire from displacing during the work process, so that the cut is more smooth.

[0004] Although the above technical solution greatly avoids the risk of electric shock during wire cutting and improves the smoothness of the cut, it can only cut off the wire, lacks auxiliary structures for stripping the wire at the same time, and requires additional tools for stripping the wire after cutting, which makes the application convenience and functionality of the entire wire cutting device general.
