Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a precise power cable stripping device. Background Art

[0002] Cable is a device for transmitting electric energy or signals. It is usually composed of several or several groups of wires and has the characteristics of internal current conduction and external insulation. Cables can be used to transmit electric (magnetic) energy and information and realize electromagnetic energy conversion. They are widely used in urban underground power grids, power station lead lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas.

[0003] During the use of existing power cable stripping devices, it is necessary to strip the outer skin of the power cable joint, and most of them are stripped by pliers, which makes it impossible to strip according to the thickness of the power cable outer skin, which can easily cause damage to the power cable core, further directly affecting the practical effect and service life.

[0007] In some embodiments, a positioning frame is fixedly provided on the upper end surface of the handle, and two groups of hydraulic telescopic rods are provided in the positioning frame, which are symmetrical up and down and can telescopically move. A clamping frame is fixedly provided on the end surface of one side of the hydraulic telescopic rod close to the symmetry center, so that the clamping frame plays a role of clamping and fixing.

[0008] Compared with the prior art, the advantages of the utility model are:

[0009] 1. The utility model is to pass the cable to be stripped through the guide cavity, and then the two sets of hydraulic telescopic rods symmetrically arranged above and below start to start, thereby driving the clamping frame to start moving toward each other, ensuring that the center of gravity of the power cable coincides with the center of the guide cavity, thereby achieving clamping and fixing of power cables of different diameters, thereby facilitating the subsequent stripping work.

[0010] 2. The utility model is to make the cutting blade contact with the outer skin of the power cable, and then clearly record the values ​​through the pointer and the scale. At this time, according to the known cable outer skin thickness, the threaded screw is rotated, and the cutting blade is inserted into the power outer skin. At this time, with the movement of the threaded slider and the pointer, the thickness of the power cable outer skin is reached, and the threaded screw is stopped.
