Description

Technical Field

[0001] The utility model relates to the technical field of cable stripping equipment, in particular to a rotating structure of a wire stripping machine. Background Art

[0002] During power maintenance, it is usually necessary to use a stripping machine to cut the skin of the overhead cable, remove the outer insulating skin, and then check the internal structure or make wire connections. When using the stripping machine, hold the handle of the stripping machine and clamp the stripping machine on the cable. After starting the power, the rotating structure on the stripping machine will make the stripping machine rotate around the cable. During the movement, the cutter on the stripping machine cuts the outer skin of the cable.

[0003] For example, a high-voltage cable stripping device disclosed in CN110011227B includes a stripping mold and a rotator, wherein the stripping mold includes an upper clamping block and a lower clamping block, and the upper clamping block and the lower clamping block are symmetrically arranged to form a clamping opening for clamping the cable, and a stripping knife is provided next to the clamping opening formed by the upper clamping block and the lower clamping block; the rotator includes a gear transmission box and a bevel gear transmission box, and the gear transmission box is connected to the bevel gear transmission box through a gear transmission rod; the stripping mold is fixedly connected to the rotator through a connecting plate, and when the rotator rotates, the stripping mold is driven to rotate by the rotator through the connecting plate.

[0004] The above technical solution uses the meshing structure of the gear and the outer gear ring to realize the rotation, such as Figure 5 As shown, since an opening needs to be provided on the outer gear ring for placing the cable inside the outer gear ring, in order to facilitate the subsequent meshing of the gear and the outer gear ring, an arc-shaped gear ring needs to be added at the opening of the outer gear ring to connect the opening so that the outer gear ring forms a full circle to ensure normal meshing. When used with an overhead cable, the arc-shaped gear ring needs to be opened and closed manually to allow the cable to enter or escape from the opening, which is inconvenient to operate and there is a risk of electric shock.

[0053] When stripping the wire, the worker holds the insulating handle 1, and the cable is sleeved inside the U-shaped opening 301. The motor 4 drives the driving gear 5 to rotate, and the driving gear 5 makes the inner gear ring 2 rotate relative to the rotating seat 3 by meshing with the driven gear 6. Since the worker holds the insulating handle 1, the rotating seat 3 rotates around the cable at this time, and the cable is stripped by the stripping tool during the rotation.

[0054] In order to facilitate the smooth rotation of the inner gear ring 2 between the two swivel seats 3, abutment protrusions 302 are provided on the opposite ends of the two swivel seats 3, wherein the abutment protrusions 302 are located on the inner side of the inner gear ring 2; the abutment protrusions 302 on the opposite ends of the two swivel seats 3 abut against each other and are fixedly connected; the inner side openings of the abutment protrusions 302 are used to install hexagon socket bolts, and the abutted abutment protrusions 302 are fixedly connected together by the hexagon socket bolts, and the abutment protrusions 302 can be maintained between the two swivel seats 3 through the abutment protrusions 302, so that the inner gear ring 2 can be maintained between the two swivel seats 3 without being clamped by the two swivel seats 3.

Specifically, an annular groove 202 is provided at the edges of both ends of the inner gear ring 2 along a first preset direction, and an annular protrusion 304 is provided at the edge of one end of the swivel seat 3 close to the inner gear ring 2 along the first preset direction, wherein the annular protrusion 304 is slidably arranged on the inner side of the annular groove 202; the first preset direction is the circumferential direction of the inner gear ring 2, when the motor 4 drives the inner gear ring 2 to rotate, the annular protrusion 304 slides on the inner side of the annular groove 202, and at the same time, during the sliding process, the inner gear ring 2 and the swivel seat 3 remain concentric through the sliding cooperation of the annular protrusion 304 and the annular groove 202.

[0058] The insulating handle 1 can be removed from the side of the inner gear ring 2. Specifically, the rotating structure of the wire stripping machine also includes a first connecting plate 9 and a second connecting plate 10, wherein the first connecting plate 9 is fixedly arranged on the side of the inner gear ring 2; the second connecting plate 10 is fixedly arranged at one end of the insulating handle 1; the first connecting plate 9 and the second connecting plate 10 are connected by bolts; when the insulating handle 1 needs to be installed, the first connecting plate 9 and the second connecting plate 10 are fixedly connected by bolts, and the bolts are clevis bolts, which are convenient for hand-tightening operations. When disassembling the insulating handle 1, the clevis bolts are removed, and then the first connecting plate 9 and the second connecting plate 10 are disassembled.

[0059] Overhead cables are generally set higher. When using a wire stripping machine, the use angle of the insulating handle 1 is adjusted according to the position of the person and the cable. In order to better maintain the adjusted angle of the insulating handle 1, a plurality of tooth grooves 901 arranged in a ring shape are provided on one end of the first connecting plate 9, and a plurality of teeth 1001 arranged in a ring shape are provided on one end of the second connecting plate 10, wherein the tooth grooves 901 and the teeth 1001 are meshed with each other, and the meshing structure is used to maintain the adjusted angle of the insulating handle 1, which is convenient for use.

[0060] The method of using the rotating structure of a wire stripping machine of the utility model is as follows:

[0061] When stripping the wire, adjust the use angle of the insulating handle 1, then hold the insulating handle 1, put the cable on the inside of the U-shaped opening 301, start the motor 4, and the motor 4 drives the active gear 5 to rotate. The active gear 5 engages with the driven gear 6 to rotate the inner gear ring 2 relative to the rotating seat 3. Since the worker holds the insulating handle 1, the inner gear ring 2 does not rotate relative to the cable at this time, and the rotating seat 3 rotates around the cable. The skin is stripped by the stripping tool during the rotation.
