Description

Technical Field

[0001] The invention relates to the technical field of armored cable wiring auxiliary equipment, in particular to a portable power cable stripping device. Background Art

[0002] When laying 750kV ultra-high voltage cables, armored cables are used in special areas. Armored cables use metal wires, metal sheets, etc. and are woven together with insulating materials as the outer covering layer of the cable, thereby forming an armor layer with a certain strength to protect the internal cable core and prevent environmental factors from damaging the cable core. However, this requires the armor layer on the outside of the cable to be stripped off when the armored cable is installed and connected. The armor layer is difficult to cut due to its high hardness, and traditional knives are inconvenient to use, so portable and applicable tools need to be designed.

[0003] Patent document CN217240155U discloses a new portable cable stripping tool, relating to the field of wire stripping tool technology. This new portable cable stripping tool includes a friction-reducing roller. By adjusting the roller to correspond to cables of different sizes, the cable's outer insulation can be quickly stripped, greatly improving work efficiency. The sharp portion of the blade is located inside the sleeve, which does not harm power workers. By changing the position of the hole on the blade, the cable cutting depth can be adjusted, and adjusting the blade's direction can achieve circular cutting of the cable's outer insulation. By separating handles B and C, a maximum opening angle of 180° can be formed, allowing the outer insulation of the cable to be stripped from all parts of the cable, rather than just starting at the cable head. However, this device suffers from inconvenient operation and unstable operation during the cable stripping process, resulting in low production efficiency. Summary of the Invention

[0028] Advantages of the present invention: (1) The portable power cable stripping device of the present invention is provided with a clamp 3 with a side opening (the left end opening is arc-shaped) in a group of two (a pair). The clamp 3 supports the support base 4 through the support rod 5. By rotating the two clamps 3 in a group to adjust the relative position between each pair of clamps 3, the opening and closing movement of the three support bases 4 of a group of clamps 3 is controlled, so that the circular cutting blade 6 on the support base 4 is inserted into the cable skin to perform circular cutting.

[0029] (2) The portable power cable stripping device of the present invention is provided with a stepping seat 14 on the support frame 1 (between the front support 19 and the rear support 20), and a mounting seat 16 is provided on the stepping seat 14 through a telescopic threaded rod 15, so that a wire cutting blade 17 is provided through the mounting seat 16, thereby realizing longitudinal cutting of the cable surface.

[0030] The working process of the present invention is as follows: When using the portable power cable stripping device of the present invention, first, the two clamps 3 of each group (a pair) are staggered, so that the three support seats 4 corresponding to each group of clamps 3 are opened, and then the portable power cable stripping device of the present invention is set on the cable through the side opening of the clamp 3, so that the three support seats 4 of each group are arranged at equal angles on the side of the cable, and then the gear 9 is rotated by the clamping handle 8, and the gear 9 pushes the two clamps 3 to rotate relative to each other on the guide seat 7 through the rack 10. At this time, the clamp 3 pushes the support seat 4 through the corresponding support rod 5, so that the three support seats 4 of each group are closed and clamped, so that the support seat 4 pushes the circular cutting blade 6 thereon to abut against and insert into the epidermis of the cable. , then hold the connecting rod 2 and push the support frame 1 to rotate, so that the support frame 1 pushes the circular cutting blade 6 to rotate and move, so that the cable is circularly cut and stripped by the circular cutting blade 6. After the circular cutting is completed, the stepping seat 14 is moved to one end (front end) of the guide rod 13, and then the telescopic threaded rod 15 is rotated to push the mounting seat 16, so that the mounting seat 16 pushes the wire cutting blade 17 to insert into the cable skin, and then the stepping threaded rod 18 is rotated by the tool, and the stepping threaded rod 18 pushes the stepping seat 14 to move backward, so that the stepping seat 14 drives the mounting seat 16 to move in a direction perpendicular to the circular cutting seam, thereby performing longitudinal cutting and stripping on the cable through the wire cutting blade 17, thereby realizing the stripping operation of the armored skin on the cable.

[0031] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
