Description

Special stripping pliers for cable grounding rings

technical field

The utility model relates to a special stripping pliers for grounding and hanging rings of cables.

Background technique

At present, in the construction process of overhead line, it is necessary to strip the insulation of the insulated cable and install the grounding ring, but there is no special stripping tool. At present, the peeling of the insulating skin is generally performed manually by using an electric knife, a wallpaper knife or a utility knife. The thicker blade of the electric knife is not easy to penetrate the main insulation layer, while the thin wallpaper knife or utility knife has a thin blade, although it is easy to penetrate the main insulation. It is also easy to cut the core wire, and even easy to hurt the construction personnel, and it is easy to cause the blade to bend or break when the force is applied. The existing tools need to perform two circumferential cuts and one longitudinal cut during operation, so the construction efficiency is low, and the cutting depth is difficult to control, and the peeling quality of the cable insulation cannot be guaranteed.

SUMMARY OF THE INVENTION

The technical problem to be solved by the utility model is to provide a special stripping pliers for cable grounding and hanging rings, which can complete the ring cutting and longitudinal cutting at one time, with accurate cutting depth and high work efficiency.

In order to solve the above-mentioned technical problems, the utility model includes a pliers handle hinged together by a hinge shaft, and its structural feature is that the inner side of the jaw end at the front end of the pliers handle is respectively provided with a peeling knife, and the peeling knife has a semi-cylindrical shape. The casing is provided with semi-annular blades at both ends in the axial direction of the casing, and a slitting blade is arranged between the two semi-annular blades, and the slitting blade is located on the center line of the inner wall of the casing in the radial direction. The inner diameter is adapted to the outer diameter of the cable to be stripped, and the radially inward extending distance of the semi-annular blade and the slitting blade relative to the inner wall of the casing is adapted to the thickness of the cable to be stripped.

The distance between the two half-ring blades is adapted to the specification of the cable to be stripped and the specification of the grounding ring to be installed.

The two half annular blades are welded or mounted on both ends of the casing in the axial direction by screws; the slitting blades are welded or inserted on the inner wall of the casing.

The housing is welded or screwed to the inside of the jaw end at the front end of the clamp handle.

The inner surface of the jaw end of the front end of the clamp handle is provided with a concave surface adapted to the outer wall of the casing.

An insulating sleeve is sleeved on the pliers handle.

After the above structure is adopted, since the peeling knife has a semi-cylindrical shell, the two ends of the shell in the axial direction are provided with semi-annular blades, and a slitting blade is arranged between the two semi-annular blades. The lever principle of the pincer structure is used. , more labor-saving; the use of the semi-ring blade and the longitudinal cutter is used to complete the peeling of the insulating skin at one time, avoiding the traditional horizontal cutting twice and the longitudinal cutting twice, which improves the efficiency; the semi-ring blade and the longitudinal cutting blade are relative to the inner wall of the shell The radially inwardly extending distance is compatible with the thickness of the cable to be stripped, so as to protect the core wire from damage; the length of the stripped insulation is accurate, which is compatible with the specifications of the grounding ring to be installed, to avoid the insulation stripped during manual cutting. There are long and short, and the construction technology standard is higher.

Fig. 2 is the structural representation of peeling knife;

FIG. 3 is a schematic view of the cross-sectional structure of FIG. 2 .

Detailed ways

Referring to the accompanying drawings, the special stripping pliers for the cable grounding ring includes a plier handle 1 hinged together by a hinge shaft 3, and the inner side of the end of the jaw 4 at the front end of the plier handle 1 is respectively provided with a peeling knife 5, and the peeling knife 5 has a semi-cylindrical The inner surface of the end of the jaw 4 at the front end of the clamp handle 1 is provided with a concave surface that is adapted to the arc surface of the outer wall of the casing. Half-ring inserts 6 are provided at both ends of the housing in the axial direction, and the half-ring inserts 6 are welded or screwed to the two ends of the housing in the axial direction. A slitting blade 7 is provided between the two semi-annular blades 6, and the slitting blade 7 is located on the center line in the radial direction of the inner wall of the casing, that is, the slitting blade 7 is located in the middle position in the radial direction of the inner wall of the casing. 7 Welded or inserted on the inner wall of the shell. The inner diameter of the casing is adapted to the outer diameter of the cable to be stripped, and the radially inwardly extending distance of the semi-annular blade 6 and the slitting blade 7 relative to the inner wall of the casing is adapted to the thickness of the cable to be stripped. When the jaws 4 are in a closed state , the trajectory of the cutting edge of the semi-annular blade 6 at both ends of the casing in the axial direction forms a complete circular trajectory. The distance between the two half-ring blades 6 is adapted to the specifications of the cables to be stripped and the specifications of the grounding rings to be installed. An insulating sleeve 2 is also sheathed on the pliers handle 1 .

Because the cable has various specifications, the thickness of the cable sheath is different for different specifications, such as: JKLGYJ-10kV 120/20 conductor cable, sheath thickness 3.5mm; JKLGYJ-10kV 240/20 conductor cable, sheath thickness 6mm. When installing the grounding ring, the cutting length of the outer sheath of these two types of conductors and cables is 4.5cm. Therefore, in actual production, according to the different specifications of the cable, a special stripper for the cable grounding ring suitable for cables of different specifications can be produced. Half-ring blade 6 And the radially inwardly extending distance of the slitting blade 7 relative to the inner wall of the housing can be 3.5mm, or 6mm, or other dimensions suitable for the thickness of the cable sheath. The distance between the two half-ring blades 6 may be 4.5 cm, or a size suitable for the specification of the grounding hanging ring to be installed. The semi-cylindrical shell is installed along the width direction of the jaw 4, that is, the axis of the semi-cylindrical shell is parallel to the axis of the hinge shaft 3. In order to prevent the blade from accidentally hurting the user, the axial length of the semi-cylindrical shell can be smaller than the jaw. 4, a protective cover can also be provided on the outside of the jaw 4.
