Embodiment 1

[0031] Such as figure 1 and figure 2 As shown: this embodiment provides a 10kV cable armor stripper, including a base 2, a ring cutting mechanism 1 is arranged in the middle of the base 2, and a center positioning mechanism 3 is arranged on both sides of the ring cutting mechanism 1, so that The two sides of the central positioning mechanism 3 are provided with a tensioning mechanism 4, and the ring cutting mechanism 1 includes an annular bracket 9, and an annular fixing groove 10 is arranged in the annular bracket 9, and an annular slider 11 is arranged in the fixing groove 10, so that A cutting blade 13 is arranged on the annular slider 11 through a telescopic push rod 12, and a rotary drive mechanism is arranged on the annular slider 11.

[0032]The ring cutting mechanism cuts off the armor of the cable. The center positioning mechanism and the stretching mechanism are arranged on both sides of the ring cutting mechanism in sequence. It is to adjust the height of the cab...

Embodiment 2

[0037] Such as image 3 As shown: the difference from Embodiment 1 is that the central positioning mechanism 3 includes columns 21 arranged on both sides of the circumcision mechanism 1, a bearing 20 is arranged on the top of the column 21, and a fine-tuning screw 17 is arranged on the bearing 20, The upper part of the column 21 is provided with a horizontal fixed rod 16 , and the two sides of the bearing 20 are provided with arc-shaped clips 18 on the fine-tuning screw 17 and the horizontal fixed rod 16 .

[0038] The two functions of fixing the tensioning cable and adjusting the center of the cable are realized by two mechanisms. The tensioning clamp on the tensioning mechanism is pulled on the two parts of the cable, and adjusted by the tensioning screw on the chute, so that the tensioning bracket moves toward the Move the outside, straighten and fix the cable, regardless of the thickness of the cable. When the cable is fixed and stretched, it is clamped by the arc-shaped ...

Embodiment 3

[0041] Such as figure 1 and figure 2 Shown: its difference with embodiment one is:

[0042] The telescopic mandrel 12 adopts a hydraulic mandrel, and the force of the hydraulic mandrel is more sufficient, and it is easy to control the telescopic distance of the mandrel to ensure the accuracy of cutting.

[0043] The telescopic ejector rod 12 is connected with the controller, and the telescopic ejector rod is connected with the controller. By realizing setting the elongation amount, the controller can control the elongation amount of the telescopic ejector rod during operation, so that the cutting blade only cuts the outer layer Armor cutting, higher precision.

[0044] The controller is a programmable logic controller. Programmable logic controller is a kind of programmable memory, which is used to store programs inside, execute logic operations, sequence control, timing, counting and arithmetic operations and other user-oriented instructions, and through digital or analog...

Abstract

The invention discloses a stripping device for an armour unit of a 10-kV cable. The stripping device comprises a pedestal; a circumferential cutting mechanism is arranged in the middle of the pedestal; center positioning mechanisms are arranged at the two sides of the circumferential cutting mechanism; and stretching-drawing mechanisms are arranged at the two sides of the center positioning mechanisms. The circumferential cutting mechanism includes an annular support; an annular fixed groove is formed inside the annular support; an annular sliding block is arranged inside the fixed groove; cutting blades are arranged at the annular sliding block by telescopic rods; and a rotary driving mechanism is arranged on the annular sliding block. According to the invention, the stripping device has a function of integrated working of armour measuring, fixation, and circumferential cutting; problems of uneven fracture, inaccurate circumferential saw notch depth, and loosening armour processing can be solved effectively; the labor intensity of the staff can be reduced; and the working time can be saved. Moreover, the stripping device has characteristics of light weight, high portability, and easy operation; and problems of heavy weight, high demand of an alternating-current power supply, and inconvenient field construction of the existing similar product in the country can be solved.

Description

technical field [0001] The invention relates to the technical field of ground wires, in particular to a 10kV cable armor stripper. Background technique [0002] In the maintenance, transformation or upgrading of the power grid, a lot of work will involve the laying and wiring of cables, especially in the construction of substations or upgrading and transformation projects, especially in the secondary work. The thin core is distinguished, and the laying and wiring work of a large number of cables plays a pivotal role in the entire project. The most critical step in cable laying and wiring work is cable stripping. Whether the cable can be stripped quickly affects the progress and quality of the entire work to a large extent. At present, the cable stripping knife we ​​use is a depth-adjustable cable stripping knife that integrates circular cutting and slitting, or a hook-shaped stripping knife. The disadvantages of these two types of peeling knives are: one is ring cutting or...
