Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a medium voltage power cable steel armor layer removing tool mainly includes a cutting portion 10 and a rotating portion 20.

The shearing portion 10:

the shear part 10 mainly includes an L-shaped lower caliper body 12, and a long hole 1211 extending in a hole-shaped longitudinal direction along the longitudinal direction of the long arm 121 is opened in the long arm 121 of the lower caliper body 12, and a hole depth direction of the long hole 1211 is parallel to the longitudinal direction of the short arm 122. An upper caliper body 11 is hinged to the middle of the elongated hole 1211, and both side surfaces of the upper caliper body 11 are attached to the corresponding side surfaces of the elongated hole 1211. The front half part of the upper forceps body 11 and the short arm 122 of the lower forceps body 12 form a jaw, and the rear half part of the upper forceps body 11 is provided with a driving assembly 13 for driving the jaw to open and close. For the jaw, the part of the upper clamp body 11 forming the jaw is an inverted v-shaped knife edge 111 structure; the portion of the lower clamp body 12 corresponding to the jaw is a plane or a cambered surface with a shape fitting the shape of the cable 30.

The driving assembly 13 includes a driving motor 131 fixed to one side of the long arm 121, and an axial direction of the driving motor 131 is perpendicular to a shearing plane of the jaws. A rotary disc 132 is coaxially fixed to an output shaft of the driving motor 131, a connecting rod 133 is hinged to a position of the rotary disc 132 near an edge, and the other end of the connecting rod 133 is hinged to a tail portion of the upper caliper body 11. When the driving motor 131 rotates, the upper clamp body 11 can be pushed to swing around the fixed shaft under the transmission action of the connecting rod 133, so that the opening and closing of the jaw are realized, and the steel armor layer is cut by opening and closing. Depending on the actual situation, the minimum degree of opening of the jaws just shears the steel armor on the cable 30, and thus does not damage the structure below the steel armor.

The rotating section 20:

the rotating part 20 comprises a positioning sleeve 21 which can be coaxially sleeved outside the cable 30, the inner diameter of the positioning sleeve 21 is the same as the outer diameter of the cable 30, and the positioning is made of metal materials; when the cable 30 is sleeved, if the cable is difficult to be sleeved on, the positioning sleeve 21 can be heated first, so that the inner diameter of the positioning sleeve is slightly increased, and the positioning sleeve can be sleeved on the cable 30 firmly. Two annular bulges which are close to each other are arranged on the outer side of the positioning sleeve 21, an annular groove is formed between the annular bulges, an annular rotary sleeve 22 is connected in the groove in a sliding manner, and the rotary sleeve 22 is connected with the lower clamp body 12 so as to drive the whole shearing part 10 to rotate around the axis of the cable 30; and the shear plane of the jaws intersects the axis of the rotating sleeve 22 perpendicularly, which enables the jaws to rotate about the axis during opening and closing, thereby effecting annular cutting of the steel armor on the cable 30.

In practical use, firstly, the positioning sleeve 21 is sleeved on the cable 30, and the jaw is adjusted to a position to be cut; at this time, the driving motor 131 is started, and the jaw starts to work; and then the steel armor layer is annularly cut by manually rotating the rotary sleeve 22.
