Description

Cable sheath removal device {STRIPPING APPARATUS FOR ELECTRIC CABLE}

The present invention relates to a cable sheath removal device, and more particularly, to a cable sheath removal device applicable to an aerial insulated three-core cable.

In general, various wire cables laid during telecommunication or electrical work must be connected to various devices after removing the coating at the end of the cable at the final stage.

A typical single-core cable has a neutral wire inside the outer shell, so the neutral layer can protect the insulating layer and semiconducting layer from the blade when the outer sheath is removed, but in the case of an aerial insulated triplex-core power aluminum cable (AITC), When removing the outer skin, the copper mylar tape must also be removed, making it difficult to precisely control the force, resulting in frequent work mistakes. In addition, while the neutral wire thickness of a general cable is 12mm (based on 400㎟), the neutral wire thickness of an insulated three-core cable is up to 0.35mm, which makes it vulnerable to sharp blades.

The background technology of the present invention is disclosed in Republic of Korea Patent Publication No. 10-1379028 (registered on March 21, 2014, title of invention: Cable sheathing stripping device).

The purpose of the present invention is to provide a cable sheath removal device capable of automatically cutting the sheath of an insulated three-core cable.

Additionally, the degree to which the running part protrudes into the inside of the main body is adjusted depending on the size of the cross-sectional area of the cable.

In addition, the running part includes an angle adjusting part that rotates around the main body in a direction away from or closer to the outer shell; and a roller unit rotatably connected to the angle adjusting unit, the position of the central axis of which varies depending on the rotation angle of the angle adjusting unit.

In addition, the running part further includes an angle maintaining part that selectively limits rotation of the angle adjusting part so that the contact state between the roller member and the outer shell is maintained.

Additionally, the angle maintaining portion presses the angle adjusting portion in a direction closer to the outer shell by an elastic restoring force.

In addition, the running portion is provided in plural pieces and individually comes into rolling contact with different surfaces of the outer shell.

Additionally, the cut portion is provided so that the cut position can be varied depending on the size of the cross-sectional area of the cable.

In addition, the incision part includes a guide part fixed to the main body and provided with a guide rail; a cutout body slidably connected to the guide rail; and a cutting member rotatably connected to the cutting body and cutting the outer skin by receiving a driving force from the driving unit.

Additionally, the guide rail extends in a direction crossing the inner and outer sides of the main body.

In addition, the guide portion further includes a stopper portion that is disposed to interfere with the movement path of the incision body and limits the range of movement of the incision body.

Additionally, the main body rotates about the central axis and moves along the longitudinal direction of the cable.

The three core wires 11 are arranged in close contact with each other to form a triangular shape. The three core wires 11 are arranged in a spirally twisted form along the longitudinal direction of the cable 10 to prevent damage at curved points. A cylindrical support made of plastic may be inserted into the center of the three core wires 11 to prevent the tilting phenomenon of each core wire. Each core wire 11 is composed of an aluminum-coated steel wire and a stranded wire, and may be formed in a structure in which a conductor layer through which a current flows, an insulating layer, a semiconducting layer, and a shielding layer are coaxially stacked.

The outer shell 12 is arranged to surround the outer peripheral surface of the three core wires 3 and supports the core wires 3. The outer shell 12 is provided to have a cross-sectional shape with three different sides as the three core wires 11 are arranged in a triangular shape. More specifically, the outer shell 12 may be formed to have a cross-sectional shape in which three curved sections and three straight sections are alternately arranged. Accordingly, different sides of the outer skin 12 may mean respective straight sections disposed between different curved sections. Different sides of the outer shell 12 are arranged in a spirally twisted form along the longitudinal direction of the cable 10, like the core wire 11. The outer shell 12 forms three empty spaces between the three core wires 11 in a triangular shape. That is, three empty spaces are arranged between different surfaces of the outer shell 12 and the outer peripheral surface of the core wire 11. The outer shell 12 may be made of flame-retardant polyethylene (PE).

The body portion 100 forms a schematic appearance of the cable sheath removal device 1 according to an embodiment of the present invention, and overall supports the running portion 200 and the cut portion 300, which will be described later. The main body 100 is arranged to face the cable 10, and is moved along the longitudinal direction of the cable 10 by the operation of the traveling part 200. The main body 100 may be made of a material with high rigidity, such as metal, to firmly support the running part 200 and the cut-out part 300 and at the same time prevent damage due to external impacts.

The main body 100 according to an embodiment of the present invention may be formed to have a hollow cylindrical shape with a through hole in the center. The main body 100 is arranged so that its inner peripheral surface is spaced apart from the cable 10, more specifically, the outer peripheral surface of the outer shell 12 by a predetermined distance. Accordingly, the main body 100 can provide a space between the cable 10 and the running part 200, which will be described later, where the running part 200 can be located. The main body 100 is arranged so that its central axis is coaxial with the central axis of the cable 10, that is, the central portion of the three core wires 11. The cross-sectional shape of the main body 100 is not limited to the circular shape shown in FIGS. 1 and 2, and various design changes are possible within the technical idea of a shape in which the inner peripheral surface can be arranged to face the outer shell 12. .

The main body 100 may be provided with a mounting part 110 on which a running part 200, which will be described later, is installed. The mounting unit 110 may be formed to have the shape of a hole that penetrates the inner and outer peripheral surfaces of the main body 100 perpendicularly in the radial direction of the main body 100 . There may be a plurality of mounting units 110, and in this case, the plurality of mounting units 110 are arranged to be spaced apart at a predetermined distance along the circumferential direction of the main body 100. Each mounting portion 110 is disposed to face different sides of the shell 12. The specific shape and size of the mounting unit 110 can be changed in various ways depending on the size of the traveling unit 200, etc.

The traveling unit 200 is rotatably installed on the main body 100. The running part 200 protrudes inside the main body 100 and comes into rolling contact with the outer sheath 12 of the cable 10. The running unit 200 rotates by receiving driving force from the driving unit 400, which will be described later, while in contact with the outer shell 12, and moves the main body 100 along the longitudinal direction of the cable 10.

The degree to which the running part 200 protrudes into the inside of the main body 100 can be adjusted depending on the size of the cross-sectional area of the cable 10. Accordingly, the running unit 200 can always maintain contact with the outer shell 12 even if the specifications of the cable 10 are changed.

The running part 200 is provided in plural numbers and is arranged to be spaced apart at a predetermined distance along the circumferential direction of the main body 100. The plurality of traveling parts 200 are individually in rolling contact with different surfaces of the outer shell 12. Each running part 200 maintains contact with different surfaces of the outer shell 12 and moves along the longitudinal direction of the cable 10. More specifically, the plurality of running parts 200 rotate the main body 100 about the central axis as different surfaces of the outer shell 12 are arranged in a spirally twisted form along the longitudinal direction of the cable 10. At the same time, it is moved along the longitudinal direction of the cable (10).

FIG. 5 is a plan cross-sectional view schematically showing the configuration of a traveling unit according to an embodiment of the present invention, and FIG. 6 is a front cross-sectional view schematically showing the configuration of a traveling unit according to an embodiment of the present invention.

Referring to Figures 5 and 6, the traveling unit 200 according to an embodiment of the present invention includes an angle adjusting unit 210, a roller unit 220, and an angle maintaining unit 230.

The angle adjusting unit 210 is rotatably connected to the main body 100. The angle adjusting unit 210 rotates around the main body 100 in a direction away from or approaching the outer shell 12 and adjusts the installation angle of the roller unit 220, which will be described later. The angle adjusting unit 210 according to an embodiment of the present invention may include a rotating shaft unit 211 and an angle adjusting member 212.

The rotating shaft portion 211 is formed to have a substantially rod shape and is disposed inside the mounting portion 110. The rotating shaft portion 211 has both ends vertically penetrating both inner surfaces of the mounting portion 110 and is supported inside the mounting portion 110 . The rotation axis unit 211 may be connected to the inner surface of the mounting unit 110 so as to be rotatable about the central axis, and may also be integrally fixed to the inner surface of the mounting unit 110. A plurality of rotation shaft units 211 may be provided and individually installed on a plurality of mounting units 110. The plurality of rotation shaft units 211 are arranged such that their central axes face parallel to different surfaces of the shell 12.

The angle adjustment member 212 is formed to have a substantially plate shape, and one side is connected to and supported by the rotation shaft portion 211. The angle adjustment member 212 is rotatably connected to the rotation shaft 211 and can be rotated relative to the rotation shaft 211. In contrast, the angle adjustment member 212 is integrally connected to the rotation shaft 211 and rotates together with the rotation shaft 211. It is also possible to become The angle adjustment members 212 may be provided in pairs and arranged to face each other at a predetermined distance along the longitudinal direction of the rotation shaft portion 211. The other side of the angle adjustment member 212 is rotatably connected to the central axis of the roller unit 220, which will be described later, and supports the roller unit 220. The other side of the angle adjustment member 212 rotates around one side and changes the position of the central axis of the roller unit 220.

The roller unit 220 is rotatably connected to the angle adjusting unit 210 and is in rolling contact with the outer shell 12. The position of the central axis of the roller unit 220 varies depending on the rotation angle of the angle adjusting unit 210. The roller unit 220 according to an embodiment of the present invention may be formed to have a cylindrical wheel shape. The central axis of the roller unit 220 is rotatably connected to the other side of the angle adjustment member 212 by a pin connection or the like. Both ends of the central axis of the roller unit 220 may be rotatably connected to the other side of the pair of angle adjustment members 212, respectively. In this case, the central axis of the roller unit 220 may be arranged in a direction parallel to the longitudinal direction of the rotation shaft unit 211. The outer peripheral surface of the roller unit 220 is in rolling contact with the outer surface of the outer shell 12. The outer peripheral surface of the roller unit 220 may be made of a material with a high coefficient of friction, such as rubber or silicone, to prevent slipping with the surface of the outer shell 12. When the cross-sectional area of the cable 10 changes, the central axis of the roller unit 220 is moved away from the outer shell 12 or closer to the outer shell 12 by the rotation of the angle adjustment member 212, and the outer peripheral surface of the roller portion 220 is moved. Maintains contact between the outer shell (12) and the outer shell (12). The specific shape and diameter of the roller unit 220 are not limited to those shown in FIGS. 5 and 6, and have a shape that is rotatably connected to the angle adjustment unit 210 and can be in rolling contact with the outer shell 12. Various design changes are possible within the range of diameter.

The angle maintaining unit 230 selectively limits the rotation of the angle adjusting unit 210 so that the contact state between the roller unit 220 and the outer shell 12 is maintained. More specifically, when the angle adjusting unit 210 is rotated to a set angle and the roller unit 220 is brought into contact with the outer shell 12, the angle maintaining unit 230 is operated by the user or by its own operation. By constraining the rotation of 210, the angle adjusting unit 210 is maintained at the set angle. Accordingly, the angle maintaining part 230 can prevent the roller part 220 from being arbitrarily released from contact with the outer shell 12 when the main body part 100 is moved along the longitudinal direction of the cable 10. It can lead to stable driving of (100).

The angle maintaining portion 230 according to an embodiment of the present invention may be formed in the form of a torsion spring that applies an elastic restoring force in the circumferential direction. Both ends of the angle maintenance unit 230 may be fixed to the inner surface of the rotation axis unit 211 and the angle adjustment member 212, or the rotation axis unit 211 and the mounting unit 110, respectively, depending on whether the parts rotate relative to each other. The angle maintaining unit 230 presses the angle adjusting unit 210 in a direction closer to the outer shell 12 by the elastic restoring force. The angle maintaining unit 230 selectively limits the rotation of the angle adjusting unit 210 according to the size of its own elastic restoring force and the size of the rotational force applied to the angle adjusting unit 210. That is, the angle maintaining unit 230 allows the angle adjusting unit 210 to rotate in a direction away from the outer shell 12 when the magnitude of the rotational force applied to the angle adjusting portion 210 is greater than the magnitude of its own elastic restoring force. And, when the magnitude of the rotational force applied to the angle adjustment unit 210 is smaller than the size of its own elastic restoring force, rotation of the angle adjustment unit 210 in a direction away from the outer shell 12 is restricted. Accordingly, when the cross-sectional area of the cable 10 changes, the angle maintaining part 230 can bring the roller part 220 into close contact with the outer shell 12 without any special manipulation by the user.

In the above, it has been described as an example that the angle maintaining unit 230 selectively limits the rotation of the angle adjusting unit 210 by its own elastic restoring force. However, the angle maintaining unit 230 is not limited to this and can be used by users such as tightening screws. Various design changes are possible within the technical idea of selectively restricting the rotation of the angle adjusting unit 210 by manipulating .

The cutting part 300 is installed in the main body 100 and is linked to the movement of the main body 100 to cut the outer skin 12. More specifically, the cutting part 300 receives a driving force from the driving part 400, moves together with the main body 100, and cuts the outer skin 12 along the longitudinal direction of the cable 10. The cut portion 300 may be provided so that the cut position can be varied depending on the size of the cross-sectional area of the cable 10. Accordingly, the cutting part 300 can cut the outer sheath 12 at the correct position even if the specifications of the cable 10 are changed.

Figure 7 is an enlarged view schematically showing the configuration of an incision according to an embodiment of the present invention.

Referring to FIG. 7, the incision 300 according to an embodiment of the present invention includes a guide part 310, an incision body 320, and an incision member 330.

The guide portion 310 is fixed to the main body 100 and movably supports the incision body 320, which will be described later. The guide unit 310 according to an embodiment of the present invention includes a guide rail 311 and a stopper unit 312.

The guide rail 311 according to an embodiment of the present invention may be formed to have the shape of a rail that protrudes vertically from the upper surface of the main body 100. The guide rail 311 extends in a longitudinal direction crossing the inner and outer sides of the main body 100. Accordingly, the guide rail 311 can guide the cutout portion 330, which will be described later, to move in the radial direction of the main body portion 100. A plurality of guide rails 311 may be provided and arranged to be spaced apart from each other in a direction perpendicular to the longitudinal direction.

The stopper portion 312 is arranged to interfere with the movement path of the incision body 320, which will be described later, and limits the range of movement of the incision body 320. That is, when the cut-out body 320 moves more than a predetermined distance along the longitudinal direction of the guide rail 311, the stopper part 312 contacts the cut-out body 320 to prevent the cut-out body 320 from moving. limit. Accordingly, the stopper portion 312 can prevent the cut-out body 320 from being separated from the guide rail 311. The stopper portion 312 according to an embodiment of the present invention may be formed to have the shape of a protrusion that protrudes vertically from the end of the guide rail 311. The stopper portion 312 may be provided as a pair and disposed at both ends of the guide rail 311, respectively. The specific shape of the stopper portion 312 is not limited to the shape shown in FIG. 7, and various design changes can be made within the technical idea of a shape that can restrict the movement of the incision body 320 in contact with the incision body 320. This is possible.

The incision body 320 is slidably connected to the guide rail 311 and supports the incision member 330, which will be described later. The cutout body 320 according to an embodiment of the present invention may be formed to have the shape of a box whose lower side is slidably connected to the guide rail 311. The width of the cutout body 320 may be formed to have a value greater than the width of the guide rail 311, and the length may be formed to have a value smaller than the length of the guide rail 311.

The cutting member 330 is rotatably connected to the cutting body 320. The cutting member 330 receives driving force from the driving unit 400 and rotates to cut the outer skin 12. The cutting member 330 according to an embodiment of the present invention may be formed so that one side is rotatably connected to the cutting body 320 and the other side has the shape of a rotating saw blade. The rotating saw blade formed on the other side of the cutting member 330 is arranged perpendicular to one of the different surfaces of the shell 12. The diameter of the cutting member 330 is such that when the cutting body 320 is moved to the front of the guide rail 311 to the maximum and contacts the stopper part 312, the front end is between the outer skin 12 and the core wire 11. It is formed to have a size that can face the empty space formed in or be placed inside the empty space. Accordingly, the cutting member 330 can prevent damage to the cable 10 by interfering with the core wire 11 when cutting the outer sheath 12.

The driving unit 400 receives power and provides driving force to the traveling unit 200 and the cutting unit 300. Accordingly, the driving unit 400 can allow the cable sheath removal device 1 according to an embodiment of the present invention to automatically move along the longitudinal direction of the cable 10 and cut the sheath 12. The driving unit 400 according to an embodiment of the present invention may be exemplified as an electric motor that outputs power supplied from an external power source or an internal battery in the form of rotational force. The driving unit 400 may be installed inside the cutout body 320, and may also be installed in the main body 100. The output shaft of the driving unit 400 is directly or indirectly connected to the roller unit 220 and the cutting member 330 so as to transmit the generated rotational force to the traveling unit 200 and the cutting unit 300. For example, the driving unit 400 may be provided in plural, so that each output shaft may be individually connected to the driving unit 200 and the cutout unit 300, and the rotational force generated from a single output shaft may be transmitted to the driving unit through a gearbox, etc. It is also possible to distribute it into (200) and the incision section (300).

Hereinafter, the operation process of the cable sheath removal device 1 will be described in detail.

Figure 8 is an operation diagram schematically showing the process of bringing the running part into close contact with the shell according to an embodiment of the present invention, and Figure 9 is an operation diagram schematically showing the process of adjusting the cut position of the incision according to an embodiment of the present invention. 10 and 11 are operational diagrams schematically showing the operation of the cable sheath removal device according to an embodiment of the present invention.

Referring to FIGS. 1 to 11 , first, the cable 10 is inserted into the central part of the main body 100.

The outer shell 12 inserted into the central part of the main body 100 presses the roller unit 220 and adds a rotational force in the opposite direction to the rotational force due to the elastic restoring force of the angle maintenance portion 230 to the angle adjustment portion 210. .

The angle adjusting unit 210 is rotated to a point where the magnitude of the rotational force caused by the elastic restoring force of the angle maintaining portion 230 and the magnitude of the rotational force applied from the outer shell 12 are balanced.

The angle at which the angle adjusting unit 210 is rotated has different values depending on the size of the cross-sectional area of the cable 10, that is, the distance (L1, L2) from the central axis of the cable 10 to the different sides of the sheath 12. You can have

The angle adjusting unit 210 is fixed at the set angle by the elastic restoring force of the angle maintaining unit 230, and the roller unit 220 is maintained in close contact with the outer surface of the outer shell 12.

Thereafter, the user slides and moves the incision body 320 with respect to the guide part 310 to adjust the incision position of the incision unit 300.

More specifically, the distance from the central axis of the cutting member 330 to the outer shell 12 is set so that the rotating blade of the cutting member 330 can interfere with the outer shell 12 when the main body 100 is moved. The incision body 320 is slid and moved in a direction that is smaller than the radius of 330).

The user stops the slide movement of the incision body 320 at a position where the front end of the incision member 330 faces the empty space formed between the outer shell 12 and the core wire 11. In this case, the slide movement of the incision body 320 may be limited by the stopper portion 312. Accordingly, the cutting member 330 can be prevented from interfering with the core wire 11 when cutting the outer skin 12.

Afterwards, the driving unit 400 generates a driving force to rotate the roller unit 220 and the cutting member 330.

As the roller part 220 in rolling contact with the outer shell 12 rotates, the main body part 100 rotates about the central axis and moves along the longitudinal direction of the cable 10.

The cutting member 330 is rotated by the driving unit 400 and simultaneously moves along the longitudinal direction of the cable 10 together with the main body 100, and forms the outer shell 12 in a spiral shape along the longitudinal direction of the cable 10. Make an incision.
