Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cable repair, and more particularly relates to a cable surface damage treatment device. BACKGROUND

[0002] As a new type of power transmission material, the core structure of the carbon fiber conductor is composed of a high-strength carbon fiber composite core, an outer aluminum cladding layer, and an insulating rubber. During long-term service, the cable rubber is prone to damage due to external mechanical friction, aging, or foreign object impact. After the rubber is damaged, the internal aluminum layer is directly exposed to the external environment, which not only may cause partial discharge and insulation performance degradation, but also accelerates the oxidation corrosion of the carbon fiber core and the electrochemical corrosion of the aluminum layer, threatening the safe and stable operation of the power grid.

[0003] Currently, in order to timely detect cable surface damage, various cable inspection devices have been developed in the prior art. Such devices usually adopt a wheel type or clamping type structure, can autonomously walk along the cable surface, and scan the cable surface through a high-definition camera or an ultrasonic detection module. When detecting defects such as rubber damage or cracks, the device can record the damage location and transmit the data to the background system in real time. Maintenance personnel need to reach the damage point by using an aerial work platform or tower climbing equipment according to the positioning information to perform manual repair.

[0004] The inventors found that the existing inspection device can only identify and mark the damage location, and cannot complete the repair work simultaneously during the inspection process, resulting in a significant disconnection in the maintenance process. Moreover, manual aerial maintenance requires a lot of time to set up the work platform, and the entire process not only has high labor intensity and low work efficiency, but also may affect the power demand of the relevant area due to long-term power outage maintenance.

[0033] Compared with the prior art, the cable surface damage processing device provided by the embodiment of the present application can realize efficient sealing and repair of the surface damage of the cable a1 through the combined process of "isolation band a2 covering + repair band a4 winding + pressing and attaching": the covering structure a3 formed by the plurality of isolation bands a2 can cover the damaged area and block the erosion of the external environment (such as moisture and dust) to the cable a1; the winding of the repair band a4 further enhances the structural strength, and cooperates with the effects of the adhesive layer and the pressing mechanism to ensure the close combination of the repair layer and the surface of the cable a1, and improves the durability after repair; the overall device can move along the cable a1 for operation, is suitable for damage processing of different lengths and positions, has high automation degree, can effectively reduce the manual operation strength, and improves the repair efficiency and consistency.

[0035] The two rotating rollers 21 are arranged on the main body 1 and are arranged side by side on the outer side of the cable a1, and each has the freedom of rotating around the central axis thereof. The axial directions of the two rotating rollers 21 are parallel to the erection direction of the cable a1.

[0036] The two ends of the release paper tape 22 are connected with the two rotating rollers 21 respectively, and the release paper tape 22 is wound around the outer periphery of the two rotating rollers 21; the isolation band a2 is attached to the outer side of the release paper tape 22, and the isolation band a2 includes a plurality of band sections arranged at intervals along the length direction of the release paper tape 22. The width of the isolation band a2 along the axial direction of the rotating roller 21 is less than the width of the release paper tape 22, and the width of the isolation band a2 along the up-down direction is less than the distance between the two rotating rollers 21; the isolation band a2 is attached to the side of the release paper tape 22 facing the cable a1.

[0037] The pushing mechanism 23 is arranged on the main body 1, located on the side of the release paper tape 22 away from the cable a1, used to push the release paper tape 22 to the outer wall of the cable a1, so that one strip section adheres to the outer wall of the cable a1 to form part of the coating structure a3. The edges of the isolation tape a2 adhered by the plurality of feeders 2 towards the cable a1 overlap with each other to form a complete coating structure a3 surrounding the outer periphery of the cable a1.

[0038] The covering mechanism further comprises a synchronous driving structure 3 connected with each rotating roller 21 to synchronously drive the plurality of rotating rollers 21 to rotate, and the rotating directions of the corresponding two rotating rollers 21 are the same.

[0039] The synchronous driving structure 3 synchronously drives the rotating rollers 21 in the plurality of feeders 2 to rotate, and the synchronous movement of the release paper tape 22 with the rotating rollers 21 can transport the surface strip section of the isolation tape a2 to the outside of the cable a1; the pushing mechanism 23 pushes the release paper tape 22 towards the cable a1 to press one strip section on the release paper tape 22 against the surface of the cable a1 to form part of the coating structure a3, and then the rotating roller 21 continues to rotate to transport the next strip section.

[0040] The plurality of feeders 2 are distributed around the cable a1, the rotating rollers 21 keep the same rotating speed through the synchronous driving structure 3 to ensure that the strip sections of the isolation tape a2 are uniformly distributed around the cable a1; the release paper tape 22 plays a role of carrying and releasing the isolation tape a2, and the pushing mechanism 23 realizes precise adhesion of the strip sections through linear driving.

[0043] The two transmission wheels 31 are respectively arranged on the two feeders 2, and each transmission wheel 31 is coaxially connected with one corresponding rotating roller 21; one transmission wheel 31 is drivingly connected with a first driving motor 33.

[0044] The transmission belt is sleeved on the outer periphery of the two transmission wheels 31 to synchronously rotate the two transmission wheels 31.

[0045] The first driving motor 33 drives one of the transmission wheels 31 to rotate, and the other transmission wheel 31 is driven to rotate synchronously through the transmission belt, so that the corresponding rotating rollers 21 in the two feeders 2 rotate in the same direction, ensuring that the isolation bands a2 on the two release paper belts 22 are synchronously conveyed to the surface of the cable a1.

[0046] The power transmission is achieved by the meshing transmission of the transmission wheels 31 and the transmission belt, the coaxial connection of the two transmission wheels 31 ensures that the rotating rollers 21 have the same rotating speed and the same rotating direction, and the movement direction of the release paper belts 22 is synchronized, avoiding the misalignment of the bonding position of the isolation bands a2.

[0053] The clamping plate 231 is connected with the main body 1 through a sliding structure, the electric push rod 232 provides linear driving force, and the first concave arc surface design makes the pressure of the clamping plate 231 uniformly distributed along the circumferential direction of the cable a1, ensuring that the isolation band a2 is completely bonded with the surface of the cable a1.

[0054] The elastic buffer layer (such as a silica gel pad) can be added on the surface of the clamping plate 231 to avoid damaging the insulation layer of the cable a1, or the pressure sensor can be integrated to realize the closed-loop control of the adhesion pressure and prevent the overpressure from causing the damage of the isolation band a2.

[0069] The switching drive component 5 can drive the swing arm 431 to swing until it contacts the covering structure a3, and the end of the repair tape a4 is attached to the covering structure a3; during the rotation of the rotating disk 41, the swing arm 431 maintains its position so that the repair tape a4 continues to wrap; after the wrapping is completed, the swing arm 431 swings to separate, and the cutting head 432 moves toward the central axis to cut the repair tape a4.

[0070] The swing arm 431 swings through a hinge structure, and its swing end guides the bonding path of the repair tape a4; the cutting head 432 moves linearly through a sliding structure, and the switching drive component 5 uses mechanical transmission to make the swing arm 431 and the cutting head 432 move in tandem, ensuring that the bonding and cutting processes are connected in an orderly manner.

[0071] A guide wheel can be added to the end of the swing arm 431 to reduce the frictional loss of the repair tape a4, or a laser cutting head 432 can be used to replace mechanical cutting to achieve non-contact tape breaking and reduce damage to the repair tape a4.

[0072] By adopting the above technical means, the swing angle of the swing arm 431 can be adjusted to adapt to the coating structure a3 of different diameters, the cutting head 432 is linked with the swing arm 431 to reduce action redundancy and improve winding efficiency; the adhesion pressure of the repair tape a4 can be adjusted by the driving force of the swing arm 431 to ensure the tightness of winding.

[0073] In some embodiments, the above-mentioned switching driving member 5 can adopt the structure as shown in Figure 8 and Figure 9 , which will be described below. Figure 8 and Figure 9 The switching driving member 5 includes a driving gear 51 and two racks 52.

[0074] The driving gear 51 is rotationally connected to the rotating disc 41, and the axial direction of the driving gear 51 is parallel to the axial direction of the rotating disc 41; the driving gear 51 is drivingly connected with a second driving motor 53.

[0075] The two racks 52 are arranged side by side on the rotating disc 41 and are both slidingly connected with the rotating disc 41.

[0076] Among them, the two racks 52 are respectively located on the two sides of the driving gear 51 and are both meshed with the driving gear 51; one of the racks 52 is hingedly connected with the swing arm 431, so that when it moves, the swing arm 431 swings synchronously; the other rack 52 is connected with the cutting head 432, so that when it moves, the cutting head 432 moves synchronously.

[0077] Among them, when the second driving motor 53 drives the driving gear 51 to rotate, the two driving gears 51 are adapted to move reversely, so that the swing arm 431 swings to be in contact with the coating structure a3, and the cutting head 432 moves away from the central axis of the rotating disc 41, or the swing arm 431 swings to be separated from the coating structure a3, and the cutting head 432 moves towards the central axis of the rotating disc 41 to cut the repair tape a4.

[0078] The second driving motor 53 drives the driving gear 51 to rotate, and the driving gear 51 meshes with the two racks 52 to move reversely; one of the racks 52 drives the swing arm 431 to swing to be in contact with the coating structure a3, and the other rack 52 drives the cutting head 432 to move away from the central axis; after winding is completed, the driving gear 51 is reversed, the swing arm 431 is separated, and the cutting head 432 moves towards the central axis to cut the repair tape a4.

[0079] The meshing transmission of the driving gear 51 and the two racks 52 converts the rotary motion into linear motion, the reverse movement of the two racks 52 on the two sides realizes the action switching of the swing arm 431 and the cutting head 432, and the forward and reverse rotation of the driving gear 51 corresponds to different process states, so that the structure is compact and the transmission precision is high.

[0080] The servo motor and the ball screw can be used to replace the gear rack 52 structure to improve the positioning accuracy of the action; or the stroke limiting switch of the rack 52 is added to prevent damage caused by overtravel of the mechanism.

[0081] By using the above technical means, single motor driving realizes double action linkage, reduces energy consumption and control complexity; gear rack 52 transmission has no risk of slipping, ensures the synchronization of the action of the swing arm 431 and the cutting head 432, and improves the reliability of the equipment.

[0082] In some embodiments, the rotating drive member 6 described above can adopt the structure as shown in Figures 1 to 8 , as shown in Figures 1 to 8 , the rotating drive member 6 includes an outer gear ring 61 and a plurality of planetary gears 62.

The outer gear ring 61 is fixedly connected with the rotating disc 41, the planetary gears 62 are connected with the main body 1 through the support, forming a planetary transmission mechanism; the plurality of planetary gears 62 are distributed around to ensure that the rotating disc 41 is uniformly stressed, and the avoiding port is designed to avoid interference with the cable a1.

[0087] By using the above technical means, the planetary transmission structure has large transmission ratio and strong carrying capacity, and is suitable for large torque winding requirements; the engagement of the plurality of planetary gears 62 improves the transmission stability, and the rotating speed of the rotating disc 41 can be adjusted to adapt to different winding densities of the repair belt a4.

[0093] When the adjusting member drives the two compression wheels 7 to move towards each other, the second concave arc surface contacts and exerts pressure on the repair tape a4 on the outer periphery of the cable a1; the heating member 72 heats the compression wheel 7, and heat is transferred from the compression wheel 7 to the repair tape a4 and the coating structure a3, thereby promoting the curing of the adhesive layer.

[0094] The compression wheel 7 is connected to the main body 1 through an elastic adjusting structure, which ensures uniform distribution of pressure; the compression wheel 7 made of a heat-conducting material realizes heat conduction, and the heating member 72 (such as an electric heating wire) provides a controllable heat source, and the temperature is adjusted to adapt to the curing needs of different adhesive layers.

[0095] A temperature sensor can be integrated inside the compression wheel 7 to realize closed-loop temperature control and prevent overheating damage to the cable a1.

[0096] By using the above technical means, the heating and pressing synergistically improve the bonding strength and the fitting speed; the second concave arc surface design is suitable for cables a1 of different diameters, and the double-wheel structure ensures uniform circumferential pressure and reduces bubbles or edge lifting of the repair tape a4.

[0100] The transmission chain 83 is sleeved on the outer periphery of the two driven sprockets and the drive sprocket 82, so that when the drive sprocket 82 rotates, the two driven sprockets rotate synchronously.

[0101] The fourth driving motor 84 drives the drive sprocket 82 to rotate, and drives the two driven sprockets to rotate synchronously through the transmission chain 83, so as to drive the two running wheels 81 to roll along the outer periphery of the cable a1, and drive the main body 1 to move as a whole; the third concave arc surface ensures that the running wheels 81 are in close contact with the cable a1, and prevents slipping.

[0102] The sprocket chain transmission realizes power transmission, the two running wheels 81 are symmetrically distributed to provide stable support, the driven sprocket is coaxially connected with the running wheel 81 to ensure consistent rotation speed, and forward and reverse rotation of the driving motor controls the forward and backward movement of the main body 1.

[0103] Rubber patterns can be additionally provided on the surface of the running wheel 81 to further improve the friction; the integrated encoder monitors the moving distance of the main body 1 in real time, and realizes accurate positioning of the repair position.

[0104] By adopting the above technical means, the chain transmission has strong bearing capacity and is suitable for long-distance cable a1 repair operation; the third concave arc surface of the running wheel 81 improves the friction between the running wheel 81 and the cable a1, and the double-wheel drive ensures that the main body 1 moves stably, and the speed can be adjusted to match the repair process rhythm.

[0108] By rotating the screw rod, the two sliding blocks can move towards or away from each other.
