Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable repair technology, specifically a device for repairing the outer sheath of power lines by wrapping. Background Technology
[0002] Power cables, as a core component of modern urban power grids, bear the crucial responsibility of transmitting electrical energy. During long-term operation, the cable's outer sheath, as the outermost protective layer, plays a vital role. However, in actual operation, the outer sheath is susceptible to damage from external environmental factors and mechanical stress, leading to breakage. When the cable sheath is damaged, current may flow through the ground, creating a circulating current loss on the cable's metallic sheath. This phenomenon causes the cable to overheat, accelerating cable aging and severely impacting its insulation life.
[0003] To address this issue, current methods for repairing cable outer sheaths primarily involve wrapping various repair tapes. However, this method has limitations. During repair, the repair tape must be manually wrapped around the damaged area of the outer sheath. Due to the instability of manual operation, it's impossible to guarantee uniform tension across different repair tapes. This can lead to the tape being too loose, creating gaps, or too tight, causing breaks. Both of these issues affect the repair effect on the cable outer sheath and reduce the cable's safety performance. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a power line outer sheath winding and repair device, which solves the problem of excessively loose or tight winding force during the existing outer sheath winding process.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a power line outer sheath winding repair device, comprising clamps clamped at both ends of the outer sheath to be repaired and a connecting rod that rotates around the clamps. The first end of the connecting rod rotates around the clamps, and the second end is provided with a wing plate. A transverse tie rod is slidably connected through the two wing plates, and a sleeve is rotatably connected to the middle of the transverse tie rod.
[0006] Preferably, the rotation of the connecting rod includes rotation in a first direction or a second direction about the clamp as the central axis, and the rotation of the sleeve includes rotation in a third direction or a fourth direction about the transverse tie rod as the central axis; wherein, when the connecting rod rotates around the clamp in the first direction, the sleeve rotates in the third direction on the transverse tie rod, and the rotation directions of the first direction and the third direction are opposite; when the connecting rod rotates around the clamp in the second direction, the sleeve rotates in the fourth direction on the transverse tie rod, and the rotation directions of the second direction and the fourth direction are opposite.
[0007] Preferably, the clamp includes a first clamping body and a second clamping body that are interlocked and wrapped around the circumference of the outer sheath. The outer sides of the first clamping body and the outer sides of the second clamping body are provided with semi-circular grooves, and the two semi-circular grooves interlock to form a circular groove.
[0008] The first end of the connecting rod is provided with a roller, which rolls in a circular groove to make the connecting rod rotate circumferentially around the clamp.
[0009] Preferably, the connecting rod includes an upper connecting rod and a lower connecting rod arranged opposite to each other. The upper connecting rod is fixed to the wing plate, the roller is rotatably connected to the bottom end of the lower connecting rod, and a rotating cylinder is rotatably connected to the upper connecting rod, and the rotating cylinder is threadedly connected to the threaded section at the top of the lower connecting rod.
[0010] Preferably, the transverse tie rod includes a first tie rod and a second tie rod arranged opposite to each other; the sleeve is installed at the opposite ends of the first tie rod and the second tie rod.

[0012] Preferably, the first and second pull rods are provided with handles at the outer ends of the wing plate.
[0013] Beneficial effects
[0014] This utility model provides a device for repairing the outer sheath of power lines. By pushing a horizontal tie rod, its bottom rotates within a circular groove formed by two interlocking semi-circular grooves. This causes the connecting rod to rotate the horizontal tie rod and the repair tape attached to it, achieving uniform winding around the outer sheath surface. No manual stretching is required, significantly reducing labor intensity. During the repair process, workers only need to operate the device to complete the winding of the repair tape, improving work efficiency. The adjustable length design of the tie rod allows the tensile strength of each repair tape to be adjusted according to actual needs. During the winding process, workers can adjust the tie rod length at any time to ensure relatively uniform tensile strength, thereby ensuring the winding effect. Furthermore, the winding speed and force of the repair tape are effectively controlled, avoiding the phenomena of being too loose or too tight during manual winding, thus improving the repair quality of the cable outer sheath.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.
[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0025] To further illustrate the technical solutions in this invention, refer to Figure 1-6 As shown, the following specific embodiments of the power line outer sheath winding repair device of this implementation plan are provided.
[0026] The repair device includes clamps 1 that are fixed to both ends of the point to be repaired on the outer sheath, and a connecting rod 2 that rotates circumferentially around the clamps 1. In an optional embodiment, the first end of the connecting rod 2 rotates circumferentially around the clamps 1, and the second end is provided with a wing plate 3. A transverse tie rod 4 is slidably connected through the two wing plates 3, and a sleeve 5 is rotatably connected to the middle of the transverse tie rod 4.
[0027] In specific implementation, refer to Figure 6As shown, one or more repair straps are put on the sleeve 5 and one end of the repair strap is glued to the outer sheath. The transverse tie rod 4 and the connecting rod 2 are driven to rotate circumferentially around the clamp 1, so that the repair strap is tightly wrapped around the outer sheath one turn at a time.
[0028] In an optional embodiment, the rotation of the connecting rod 2 includes rotation in a first or second direction about the clamp 1 as the central axis, meaning the connecting rod 2 can rotate in both directions around the outer sheath on the clamp 1; the rotation of the sleeve 5 includes rotation in a third or fourth direction about the transverse tie rod 4 as the central axis, meaning the sleeve 5 can rotate in both directions while rotating on the transverse tie rod 4. The crossbeam tie rod 4 and the connecting rod 2 are rotated in different directions on the clamp 1 according to the orientation of the maintenance tape placement, so as to facilitate wrapping the maintenance tape around the surface of the outer sheath.
[0029] When the connecting rod 2 rotates around the clamp 1 in the first direction, the sleeve 5 rotates on the transverse tie rod 4 in the third direction, and the rotation directions of the first direction and the third direction are opposite; when the connecting rod 2 rotates around the clamp 1 in the second direction, the sleeve 5 rotates on the transverse tie rod 4 in the fourth direction, and the rotation directions of the second direction and the fourth direction are opposite.
[0030] In one alternative embodiment, such as Figure 2 As shown, the clamp 1 includes a first clamping body 11 and a second clamping body 12 that are interlocked and wrapped around the circumference of the outer sheath. Semi-circular grooves 13 are provided on the outer sides of both the first clamping body 11 and the second clamping body 12, and the two semi-circular grooves 13 interlock to form a circular groove. A roller 7 is provided at the first end of the connecting rod 2, and the roller 7 rolls within the circular groove to allow the connecting rod 2 to rotate circumferentially around the clamp 1.
[0031] like Figure 3 As shown, the bottom of the connecting rod 2 is provided with an arc-shaped plate, and the roller 7 is connected to the arc-shaped plate.
[0032] Before use, slide the arc-shaped piece at the bottom of the connecting rod 2 into the semi-arc groove 13 on the outside of the first clamp body 11, then place the second clamp body 12 at the bottom of the outer sheath, and then fix the first clamp body 11 with the connecting rod 2 in it onto the second clamp body 12 with bolts to achieve the connection and fixation of the first clamp body 11 and the second clamp body 12. At this time, it is necessary to ensure that the arc-shaped piece can move in the circular groove through the roller 7 and rotate in both directions in the circular groove.
[0033] In the above steps, it should be noted that after the first clamping body 11 and the second clamping body 12 are connected and fixed, it must be ensured that they cannot move or rotate on the outer sheath. When the bolts are partially loosened, the first clamping body 11 and the second clamping body 12, which are still in the connected state, can move laterally on the outer sheath. When the first clamping body 11 and the second clamping body 12 are in the completely disassembled state, they can be detached from the outer sheath.
[0034] In one alternative embodiment, such as Figure 5 As shown, connecting rod 2 is an adjustable rod with an adjustable length, including an upper connecting rod 21 and a lower connecting rod 24 arranged opposite to each other. The upper connecting rod 21 is fixed to the wing plate 3, and the roller 7 is rotatably connected to the bottom end of the lower connecting rod 24. A rotating drum 22 is rotatably connected to the upper connecting rod 21, and the rotating drum 22 is threadedly connected to the threaded section 23 at the top of the lower connecting rod 24. Manually rotating the rotating drum 22 causes its top to rotate on the upper connecting rod 21. During forward and reverse rotation, the rotating drum 22 moves up and down on the lower connecting rod 24 through the threaded engagement with the threaded section 23, allowing the lower connecting rod 24 to rotate in and out of the rotating drum 22, thus achieving length adjustment of the connecting rod 2.
[0035] In an alternative embodiment, the transverse tie rod 4 includes a first tie rod 41 and a second tie rod 42 disposed opposite to each other; a sleeve 5 is installed at the opposite ends of the first tie rod 41 and the second tie rod 42.
[0036] Furthermore, such as Figure 4 As shown, the sleeve 5 includes a first side plate 51 rotatably connected to the first pull rod 41 and a second side plate 53 rotatably connected to the second pull rod 42. A cylinder 52 is fixed to the inner side of the first side plate 51, and a connecting seat 54 is provided on the inner side of the second side plate 53. The cylinder 52 is threadedly connected to the connecting seat 54. The sleeve 5 adopts a detachable connection design, which makes it easy to put the maintenance strap on the cylinder 52. In use, the first side plate 51 or the second side plate 53 is rotated to separate the cylinder 52 from the connecting seat 54, the maintenance strap is put on the cylinder 52, and then the cylinder 52 is reconnected to the connecting seat 54.
[0037] The aforementioned connecting tapes include, but are not limited to, insulating self-adhesive tape, rubber insulating self-fusing tape, waterproof insulating tape, and armored tape.
[0038] The first pull rod 41 and the second pull rod 42 are provided with handles 6 at the outer ends of the wing plate 3.
[0039] Working principle:
[0040] Step 1: Sequentially place the insulating self-adhesive tape, rubber insulating self-melting tape, waterproof insulating tape and armor tape on the cylinder 52, and rotate the first side plate 51 or the second side plate 53 to connect the cylinder 52 with the connecting seat 54.
[0041] Step 2: Slide the arc-shaped piece at the bottom of the connecting rod 2 into the semi-arc groove 13 on the outside of the first clamping body 11, then place the second clamping body 12 at the bottom of the outer sheath, and then fix the first clamping body 11 with the connecting rod 2 in it onto the second clamping body 12 with bolts to achieve the connection and fixation of the first clamping body 11 and the second clamping body 12.
[0042] Step 3: Clean impurities from the surface of the outer sheath, then wipe the surface of the outer sheath with an alcohol cloth. Attach one end of the insulating self-adhesive tape to the outer sheath. Push the transverse pull rod 4 so that its bottom rotates within a circular groove formed by the interlocking of two semi-circular grooves 13. This causes the connecting rod 2 to rotate the transverse pull rod 4 and the repair tape on it, wrapping it around the surface of the outer sheath. Furthermore, push the transverse pull rod 4 laterally, causing it to move laterally within the wing plate 3, allowing the insulating self-adhesive tape to wrap around and cover the point to be repaired.
[0043] Step 4: Replace the rubber insulating self-fusing tape, waterproof insulating tape, and armor tape in sequence to complete the repair.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
