Description

Technical Field

[0001] This utility model belongs to the field of power facility maintenance technology, specifically relating to a cable insulation restoration device. Background Technology

[0002] In power systems, cables often face several problems during use. For example, during power system maintenance or expansion, maintenance tools or clamps may damage the outer insulation layer of the cable, or the insulation layer may be damaged after the temporary clamps are removed. These scenarios result in exposed points on the cable. If any object comes into contact with these exposed points, phase-to-phase short circuits or grounding accidents can easily occur. Furthermore, gaps exist between the inner metal conductors and the outer insulation layer of exposed cables, allowing rainwater and corrosive gases to penetrate, thus accelerating cable aging. Therefore, maintaining the integrity of the cable insulation layer is crucial for ensuring the safe operation of power equipment; once exposed cable conductors are discovered, insulation repair must be carried out promptly.

[0003] However, traditional insulation restoration work largely relies on manual operation, that is, manually wrapping insulating tape around the exposed cable sections. But this method has many uncertainties. For example, the number of wraps often depends on personal experience, and for long exposed sections, the insulating tape may be wrapped unevenly. At the same time, uneven wrapping force can also lead to poor sealing of the insulating tape. Manual operation requires a lot of time and effort, especially when dealing with large high-altitude equipment or complex insulation structures, where efficiency is particularly low.

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] Please see Figure 1 and Figure 8 A cable insulation restoration device includes: a frame 1, a first drive assembly 2, a clamping assembly 3, a second drive assembly 4, and an adhesive application assembly 5.

[0038] The first drive assembly 2 and the second drive assembly 4 are mounted on the frame 1. The clamping assembly 3 is connected to the output end of the first drive assembly 2. The first drive assembly 2 is used to drive the clamping assembly 3 to clamp or release the cable 6. The adhesive application assembly 5 is disposed in the frame 1 and connected to the output end of the second drive assembly 4. The second drive assembly 4 is used to drive the adhesive application assembly 5 to rotate 360° around the axis of the cable 6. Specifically, a first mounting bracket 11 is provided on the bottom outer surface of the frame 1. The first mounting bracket 11 has a mounting groove 111. Using the existing technology of the insulating operating rod 8, the insulating operating rod 8 is installed in the frame 1 by hexagonal bolts. The adhesive application assembly 5 is used to carry the insulating tape 7.

[0039] This utility model discloses a cable insulation restoration device. In use, firstly, the insulating operating rod 8 is installed in the frame 1. The angle between the insulating operating rod 8 and the frame 1 is adjusted, and the hexagonal bolts are tightened, fixing the insulating operating rod 8 to the frame 1. Next, insulating tape 7 is applied flat to the adhesive application component 5. The insulating operating rod 8 is then operated to insert the cable 6 into the device, moving the device until the exposed position of the cable 6 is above the insulating tape 7. Then, the first drive component 2 is activated, driving the clamping component 3 to clamp the cable 6, at which point the cable 6 is stationary relative to the device. Next, the second drive component 4 is activated, driving the adhesive application component 5 to apply the tape 7 and rotate around the cable 6. The adhesive application component 5 completes the application of the insulating tape 7 by rotating 360° around the cable 6. After completion, the first drive component 2 is activated in reverse, driving the clamping component 3 to release the cable 6. The insulating operating rod 8 is then operated, moving the device from the cable 6 to a safe position, and the clamping component 3 is reset. The above operation process automatically attaches and wraps the device to the exposed part of the cable 6 to restore insulation. This not only ensures the safety of the operation process, but also avoids the uncertainty of human operation and improves the repair efficiency.

[0040] Further, please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8The adhesive application assembly 5 includes a tray frame 51, a tray 52, a pressing structure 53, a torsion spring 54, and an initial positioning structure 55. The tray frame 51 is connected to the output end of the second drive assembly 4 and is rotatably mounted in the frame 1. The tray 52 is mounted in the tray frame 51. The pressing structure 53 is located above the tray 52 and applies pressure to the insulating tape 7. One end of the torsion spring 54 abuts against the back of the tray 52, and the other end abuts against the tray frame 51. One end of the initial positioning structure 55 is located in the frame 1, and the other end is connected to the tray frame 51. Specifically, the tray frame 51 includes a left tray frame 511 and a right tray frame 512. The tray frame 51 also includes a rotating shaft 513. A cable support seat 14 is provided between the frame 1 and the tray frame 51. One end of the rotating shaft 513 is connected to the second drive assembly 4, and the other end passes through the tray frame 51 and connects to the cable support seat 14. The rotating shaft 513 is installed on a side offset from the center of the width of the tray frame 51, allowing the tray frame 51 to rotate around the rotating shaft 513. The tray 52 is welded between the left tray frame 511 and the right tray frame 512, and is used to carry the insulating tape 7. Two sets of torsion springs 54 are provided, respectively sleeved on both ends of the rotating shaft 513. The tray frame 51 has a fixing post 514; one end of the torsion spring 54 abuts against the back of the tray 52, and the other end abuts against the fixing post 514. One end of the initial positioning structure 55 is set on the frame 1, and the other end is connected to the right rubber tray frame 511. When the rubber tray 52 is in a horizontal position, without external force, the initial positioning structure 55 applies a force to the rubber tray frame 51 to keep the rubber tray 52 in a horizontal position, while the torsion spring 54 is compressed and stores energy. The adhesive application assembly 5 also includes a limiting post 57. One end of the limiting post 57 is welded and installed on one side of the left rubber tray frame 511, and the other end is suspended. The limiting post 57 limits the rotation direction and rotation angle of the rubber tray frame 51 to prevent equipment damage. Preferably, the limiting post 57 is made of rubber. The insulating tape 7 includes a base layer 71 and an insulating cloth 72. The base layer 71 is double-sided adhesive, and the insulating cloth 72 is adhesive on one side for pasting on the exposed position of the cable 6, and non-adhesive on the other side. When producing the insulating tape 7, the non-adhesive side of the insulating cloth 72 is pasted on the base layer 71. In use, first cut the required length of insulating tape 7 from the insulating tape loop, and apply it flat to the tape tray 52 starting near the pressing structure 53. Tear off one end of the insulating tape 7 to separate the bottom layer 71 and the insulating tape 72 along the length direction. The pressing structure 53 presses down on the bottom layer 71 and further applies pressure to the bottom layer 71 from one end to prevent it from moving during operation, thus improving the stability of the insulating tape 72 on the cable 6. Then, start the second drive assembly 4. The second drive assembly 4 drives the tape tray frame 51 to rotate through the rotating shaft 513, causing the tape tray 52 to rotate synchronously. The cable support base 14 rotates synchronously with the rotating shaft 513.When the tape holder 51 rotates, it overcomes the force exerted on the tape holder 51 by the initial positioning structure 55, and the tape holder 51 disengages from the initial positioning structure 55. Under the elastic force of the torsion spring 54, the tape 52 adaptively adheres to the cable 6. The second drive assembly 4 continues to drive the tape holder 51 to rotate, causing the tape 52 to rotate continuously 360°, completing the action of applying insulating tape 7 around the cable 6.

[0041] Further, please refer to Figure 3 The pressing structure 53 is a magnetic pressure strip 531. The contact area between the rubber tray 52 and the magnetic pressure strip 531 is made of iron material, and the rubber tray 52 and the magnetic pressure strip 531 are magnetically connected. In use, the magnetic pressure strip 531 is removed by overcoming the magnetic force. The insulating tape 7 is laid flat on the surface of the rubber tray 52. ​​The insulating tape 7 is torn open to partially separate the bottom layer 71 and the insulating cloth 72. The magnetic pressure strip 531 is then lowered, and the bottom layer 71 is pressed onto the rubber tray 52 by magnetic force. The insulating cloth 72 can detach from the bottom layer 71 when subjected to the upper force.

[0042] Please see Figure 4 In another embodiment of the pressing structure 53, the pressing structure 53 includes a pressing plate 532 and two adjusting bolts 533. Threaded holes are provided on one side edge of the rubber tray 52 near both ends of the rubber tray frame 51. The adjusting bolts 533 pass through the pressing plate 532 and are threadedly connected to the threaded holes. The distance between the pressing plate 532 and the surface of the rubber tray 52 is adjusted by threading, thereby pressing or loosening the bottom layer 71. In use, first remove the pressing plate 532, lay the insulating tape 7 flat on the surface of the rubber tray 52, tear off the insulating tape 7 to partially separate the bottom layer 71 and the insulating tape 72, press the pressing plate 532 onto the bottom layer 71, and thread the adjusting bolts 533 through the pressing plate 532 and connect them to the threaded holes. Tighten the adjusting bolts 533, at which point the pressing plate 532 presses the bottom layer 71 tightly.

[0043] Further, please refer to Figure 3 The initial positioning structure 55 includes a magnetic reset block 551 and an iron block 552. The magnetic reset block 551 is mounted on the frame 1, and the iron block 552 is mounted on the side of the tray frame 51 near the magnetic reset block 551. The tray frame 51 and the magnetic reset block 551 are magnetically connected. Specifically, when the tray 52 is horizontal, the magnetic reset block 551 and the iron block 552 are magnetically attracted together, and the magnetic force is greater than the elastic force of the torsion spring 54. Therefore, in standby mode, the reset block 551 and the iron block 552 can be manually attracted together, keeping the tray 52 in a horizontal position. After the insulating tape 7 is applied to the tray 52, the second drive assembly 4 drives the tray frame 51 to rotate. After overcoming the magnetic force, the magnetic reset block 551 disengages from the iron block 552, and the tray 52 can then adaptively adhere to the cable 6 under the action of the torsion spring 54.

[0044] Please see Figure 4In another embodiment of the initial positioning structure 55, the initial positioning structure 55 includes an elastic column 553, which is disposed on the frame 1. The rubber tray frame 51 has a guide groove 554 and a positioning groove on the side near the elastic column 553, with the guide groove 554 and the positioning groove transitioning by an arc. The rubber tray 52 is kept horizontal by the friction between the elastic column 553 and the positioning groove. The second drive assembly 4 drives the rubber tray frame 51 to rotate, and after overcoming the friction, the elastic column 553 disengages from the positioning groove along the guide groove 554. Preferably, the elastic column 553 is an elastic rubber column.

[0045] Further, please refer to Figure 2 The adhesive application assembly 5 also includes an adhesive application roller 56, which is rotatably mounted in the adhesive tray frame 51. Specifically, one end of the adhesive tray frame 51 has a support base, and the other end has a rotating hole. One end of the adhesive application roller 56 is rotatably connected to the support base, and the other end is installed in the rotating hole. The adhesive tray 52 has a through groove 521, and the adhesive application roller 56 is set in the through groove 521, so that the height of the adhesive application roller 56 above the adhesive tray 52 is moderate. With this structure, the rotation of the adhesive tray 52 drives the adhesive application roller 56 to rotate through the insulating tape 7. Therefore, during the application of the insulating tape 7, the adhesive application roller 56 applies a force to the insulating tape 7 to move it toward the cable 6, and the force is evenly distributed, so that the insulating tape 7 is well sealed on the cable 6. After the insulating tape 7 is applied, because the adhesive application roller 56 is higher than the adhesive tray 52, the bottom layer 71 can be easily peeled off from the adhesive tray 52, which is convenient for the next application of insulating tape 7.

[0046] Further, please refer to Figure 2 The surface of the tape 52 is marked with size scale 522. The outer diameter of the cable 6 varies depending on the cable specification, and the required length of insulating tape 7 varies. This structure makes it convenient for construction personnel to cut the appropriate length according to the cable 6 specification, instead of relying on experience to estimate the length or measuring with a ruler. This avoids the possibility of the length being too long or too short due to estimation. It not only reduces the time for tool measurement, but also ensures that the insulating tape 7 is evenly wrapped around the cable 6.

[0047] Further, please refer to Figure 1 and Figure 5The first drive assembly 2 includes a first drive source 21 and a lead screw 22. The lead screw 22 has a first threaded section 221 and a second threaded section 222 with opposite directions of rotation. The clamping assembly 3 includes a first clamping block 31 and a second clamping block 32. The first clamping block 31 is threadedly connected to the first threaded section 221, and the second clamping block 32 is threadedly connected to the second threaded section 222. Specifically, a second mounting bracket 12 is provided on the side of the frame 1. The first drive source 21 is installed in the second mounting bracket 12, and the lead screw 22 passes through the second mounting bracket 12 and is installed at the output end of the first drive source 21. The first clamping block 31 and the second clamping block 32 are respectively provided with through threaded holes 311. The first clamping block 31 and the second clamping block 32 are respectively threadedly connected to the lead screw 22. When the first drive assembly 2 is activated, the first clamping block 31 and the second clamping block 32 are driven to move closer or further away from each other, so that the first clamping block 31 and the second clamping block 32 simultaneously clamp or release the cable 6. When clamping the cable 6, it provides centering clamping. Preferably, the first drive assembly 2 and the clamping assembly 3 are provided in two sets, respectively installed on both sides of the frame 1. Preferably, the first drive source 21 is a motor.

[0048] Further, please refer to Figure 5 The first drive assembly 2 also includes a guide rod 23, which is installed parallel to the lead screw 22 in the frame 1. The first clamping block 31 and the second clamping block 32 are both provided with through guide holes 312, and the first clamping block 31 and the second clamping block 32 move along the guide rod 23. Specifically, one end of the guide rod 23 is welded to the surface of the second mounting bracket 12, and the other end is fixedly installed on the upper end of the frame 1. Preferably, two sets of guide rods 23 are provided, symmetrically installed on both sides of the lead screw 22.

[0049] Further, please refer to Figure 5 The first clamping block 31 and the second clamping block 32 are provided with grooves 313 that fit the shape of the cable 6. Specifically, the grooves 313 are C-shaped, V-shaped or U-shaped, and preferably, the inner wall of the grooves 313 is covered with a layer of rubber.

[0050] Further, please refer to Figure 6The second drive assembly 4 includes a second drive source 41, a drive gear 42, a first driven gear 43, a second driven gear 44, and a third driven gear 45. The drive gear 42 is mounted on the output end of the second drive source 41. The first driven gear 43 and the second driven gear 44 are symmetrically arranged about the axis of the drive gear 42, and the drive gear 42 simultaneously meshes with the first driven gear 43 and the second driven gear 44. The third driven gear 45 simultaneously meshes with the first driven gear 43 and the second driven gear 44. The third driven gear 45 is a non-full gear. The adhesive applicator 5 is connected to the third driven gear 45. The third driven gear 45 has an arc cavity 451 for accommodating the cable 6 and an opening 452 for the cable 6 to enter and exit. The opening 452 communicates with the arc cavity 451. Specifically, the adhesive tray frame 51 is connected to the third driven gear 45 through one end of the rotating shaft 513. The width of the adhesive tray frame 51 is less than the vertical distance from the axis of the driving gear 42 to the axis of the first driven gear 43, allowing the adhesive tray 52 to rotate 360°. The shape of the cable support base 14 matches the shape of the third driven gear 45, and it has a through support arc cavity 141 with the same shape as the arc cavity 451. In use, the second drive source 41 is started, driving the driving gear 42 to rotate, which in turn drives the first driven gear 43 and the second driven gear 44 to rotate in opposite directions. Through the meshing of the third driven gear 45 and two symmetrically arranged gears (the first driven gear 43 and the second driven gear 44), the third driven gear 45 rotates around the center of the arc cavity 451. The third driven gear 45 simultaneously drives the adhesive tray frame 51 and the cable support base 14 to rotate through the rotating shaft 513, so that the adhesive tray 52 rotates 360° to complete the action of wrapping the cable 6 with insulating tape 7. The third driven gear 45 is provided with an opening 452 and an arc cavity 451. After the cable 6 is covered with insulating tape 7, it is disconnected from the device through the opening 452. Preferably, the second drive source is a motor.

[0051] Further, please refer to Figure 1 The frame 1 has a side frame 13 that matches the shape of the third driven gear 45. Specifically, there are two sets of side frames 13, including a left frame 131 and a right frame 132, which are respectively arranged on both sides of the frame 1. The frame 1 has a working cavity 133, in which the second drive assembly 4 is arranged. Part of the third driven gear 45 is exposed inside the left frame 131. The cable support 14 is arranged between the inner sides of the rubber tray frame 51 and the right frame 132. When the cable 6 is not clamped, such as when the device has just put the cable 6 in or when the cable 6 is released after the operation of applying insulating tape 7, the contact area between the cable 6 and the device is increased, making it less likely for the cable 6 to detach from the device.

[0052] This utility model discloses a cable insulation restoration device. By setting a first driving component 2 and a clamping component 3, the cable 6 can be centrally clamped, ensuring the stability of subsequent application of insulating tape 7. The second driving component 4 and the adhesive application component 5 enable rapid insulation restoration of the cable 6, avoiding the uncertainty of manual operation and improving efficiency. The insulated operating rod 8 and the device keep the operator away from the cable 6, ensuring their safety during operation. An initial positioning structure 55 and a torsion spring 54 are provided. In standby mode, pressing the initial positioning structure 55 keeps the adhesive tray 52 horizontal, preventing the device from touching the insulating tape 7 when it is applied to the cable 6. When the device rotates, the initial positioning structure 55 disengages, and the adhesive tray 52 adaptively adheres to the cable 6 under the action of the torsion spring 54. An adhesive application roller 56 ensures good sealing of the insulating tape 7 on the cable 6, and the bottom layer 71 is easily peeled off from the adhesive tray 52.

[0053] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific implementation method of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the spirit of this utility model should be included within the protection scope of this utility model.
