Embodiment 1

[0049] refer to Figure 2-Figure 5 , the high-voltage cross-linked polyethylene insulated power cable outer sheath and the insulation layer stripping tool provided in this embodiment include a cutting mechanism 2, the cutting mechanism 2 is a cube structure, and the upper parts of the left and right sides are provided with holes that penetrate the cutting mechanism 2 in the left and right directions. Left and right arc-shaped grooves 21, the upper part of the rear side is provided with a rear arc-shaped groove 22 that runs through the cutting mechanism 2 in the front and rear direction; the specifications of the left and right arc-shaped grooves 21 and the rear arc-shaped groove 22 are consistent, and the central axes are located Above the mechanism 2 and at the same height, the central axes are perpendicular to each other and parallel to the bottom surface of the cutting mechanism 2; diameter) match.

[0050] The top of cutting mechanism 2 front sides is provided with front ...

Embodiment 2

[0056] refer to Figure 6-Figure 8 Compared with Embodiment 1, the high-voltage XLPE insulated power cable outer sheath and insulation layer stripping tool provided in this embodiment have been improved as follows: the left and right arc grooves 21 are not provided, and the cutting direction can be adjusted by the blade 24. .

[0057] Such as Figure 7 As shown, the root of the blade of the blade 24 is provided with a cylindrical turntable 241, the central axis of the turntable 241 is collinear with the blade of the blade 24, and the bottom of the turntable 241 is provided with a coaxial threaded rod, and the threaded rod is provided with a The matching knurled nut 242 is used to fix the blade 24 on the cutting mechanism 2 .

[0058] Corresponding, such as Figure 8 As shown, the upper and lower axes of the cutting mechanism 2 are hollowed out with a mounting hole 232 that is in clearance with the threaded rod at the bottom of the turntable 241, and the upper and lower axes...

Embodiment 3

[0062] refer to Figure 9 , the high-voltage cross-linked polyethylene insulated power cable outer sheath and the insulation layer stripping tool provided by this embodiment have been improved as follows compared with embodiment 2: no positioning column 25 and positioning hole 26 are provided, and the cutting mechanism 2 top Fastening holes 27 are hollowed out near the two corners of the front arc groove 23;

[0063] When the insulation layer 13 needs to be cut, the two cutting mechanisms 2 can be arranged oppositely, and the fastening rod 3 can pass through the two relative fastening holes 27. The fastening rod 3 is a threaded rod, so the nut can be used to The two front arc-shaped grooves 23 are pressed against the insulating layer 13 to prevent the cutting mechanism 2 from slipping when rotating.

[0064] In this embodiment, one end of the fastening rod 3 connected to the cutting mechanism 2 is provided with a multi-angle limiter 32. In order to prevent the fastening rod 3...

Abstract

The invention provides a tool for stripping an outer sheath and an insulating layer of a high-voltage cross-linked polyethylene insulated power cable, and belongs to the technical field of power construction. The tool comprises a cutting mechanism of a cubic structure; a rear arc-shaped groove penetrating through the cutting mechanism is formed in the upper portion of the rear side of the cutting mechanism, and the inner diameter of the rear arc-shaped groove is matched with the outer diameter of the high-voltage power cable; a front arc-shaped groove is formed in the upper portion of the front side of the cutting mechanism, the bottom of the front arc-shaped groove is lower than the bottom of the rear arc-shaped groove, and the inner diameter of the front arc-shaped groove is matched with the outer diameter of an insulating layer of the high-voltage power cable; threads are arranged on the inner side of the front arc-shaped groove, and a blade used for cutting is arranged at the bottom of the front arc-shaped groove; and the top end of the blade is pointed, the side, making contact with the top end of the blade, of the blade is a cutting edge, and the cutting edge and the upper and lower axis of the cutting mechanism are collinear. The tool has the functions of ring cutting, transverse cutting and rotary cutting at the same time, and can achieve cutting of an outer sheath and cutting of an insulating layer of a high-voltage power cable.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, and in particular relates to an outer sheath of a high-voltage cross-linked polyethylene insulated power cable and a tool for stripping an insulating layer. Background technique [0002] When it is necessary to connect high-voltage XLPE insulated power cables or make high-voltage cable terminals, it is necessary to strip the outer sheath and insulation layer of the high-voltage power cables to expose the conductor in the center of the cable. At present, an electrician's knife or a paper cutter is often used when stripping the outer sheath of a high-voltage power cable. The outer sheath is hard and smooth. It is necessary to grasp the strength and angle during the stripping process. It is not easy for the operator to operate. Not only is the efficiency low when stripping the outer sheath, but also it is easy to cause injury to the staff when used improperly. [0003] In view o...
