Description

Technical Field

[0001] The invention belongs to the technical field of cable repair, in particular to a cable repair device and a repair method. Background Art

[0002] Cables have many uses, mainly for controlling installation, connecting equipment, transmitting electricity and other multiple functions. Depending on the different application fields, some cables will be assembled by burying them in the soil. At present, when the cables buried in the soil are impacted by external forces, once the external force is too large, it will cause partial damage to the cables. As the insulation layer of the cable is damaged, its internal core wire will be affected by the accumulation of water in the soil and fail. Therefore, it is necessary to use excavation equipment to dig up the soil, and then use repair equipment to repair the cables.

[0003] A patent application with publication number CN117438975B discloses an automatic cable repair device, which clamps and lifts the cable through two sets of bottom clamp rings and top clamp rings, and then fixes an external frame in the middle of the rod body inside the base, and movably installs pads that can be erected on both sides of the gully on the outside of the external frame, and movably installs a driveable external frame to move vertically up and down inside the pad. At this time, the cable calibration mechanism fixed by the external frame and suspended at the center of the gully can provide a calibration platform for the damaged part of the cable. At this time, the part of the cable to be repaired buried under the soil can be isolated from the moist medium in the gully, and then the protective shell is driven to rotate along the cable, and the insulating rubber roller can automatically insulate and wrap the part of the cable that is suspended and lifted, thereby effectively avoiding the problem of soil falling hindering the cable repair, and realizing the cable repair work.

[0004] In the actual application of the above-mentioned prior art, since the insulating rubber roller is composed of multiple spliced ​​parts, when the damaged part of the cable is wound to repair it, the insulating tapes released by the insulating rubber roller are not overlapped and wound around the outside of the cable, which leads to gaps between the multiple insulating tapes. In the later stage, there is still a situation where malfunctions occur due to water accumulation. Moreover, when winding the insulating tape, if the dirt or dust on the surface of the cable is not cleaned, the insulation performance of the cable will be reduced, increasing the risk of leakage or short circuit, and affecting the adhesion between the cable and the insulating tape, causing the tape to detach or shift.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figure 1-8 , the present invention provides a technical solution:

[0044] A cable repair device comprises a support frame 1, two mounting blocks 3 are fixedly connected to both ends of the support frame 1, and a cable repair hoisting assembly 4 is arranged on one side of the two mounting blocks 3;

[0045] The cable repair lifting assembly 4 includes a fixed column 403 fixed to one side of the mounting block 3, and the fixed column 403 is rotatably connected to the outside with a first clamping jaw 401 and a second clamping jaw 402, and the first clamping jaw 401 and the second clamping jaw 402 are symmetrically arranged in a circle, and are used to clamp and lift underground cables;

[0046] Two fixing blocks 24 are fixedly connected between the two mounting blocks 3, and two semicircular fixing frames 5 are fixedly connected between the two fixing blocks 24. A T-shaped limiting groove 19 is provided between the two semicircular fixing frames 5. A semicircular rotating frame 6 is rotatably connected to the inner cavity of the T-shaped limiting groove 19. A cleaning cylinder 7 is fixedly connected between the semicircular rotating frames 6. An auxiliary repair component 9 is provided in the inner cavity of the cleaning cylinder 7.

[0047] The auxiliary repair assembly 9 includes a slider 901 slidably connected to the inner cavity of the cleaning cylinder 7, one end surface of the slider 901 is fixedly connected to a support plate 902, and the inner cavity of the support plate 902 is slidably connected to two clamping blocks 903, and the two clamping blocks 903 are used to clamp and install the insulating rubber roller 16;

[0048] A telescopic rod 2 is installed at the upper end of the support frame 1, and a fixed rod 11 is slidably connected to the outside of the telescopic rod 2.

[0049] Specifically, in the prior art, multiple sets of insulating rubber rollers are driven to rotate around the cable, and then the damaged parts of the cable are wound and repaired. However, the insulating tapes released by the insulating rubber rollers are not overlapped and wound around the outside of the cable, which results in gaps between the insulating tapes. In the later stage, there is still a situation where the cable is affected by the accumulation of water and fails. Moreover, when the insulating tape is wound, if the dirt or dust on the surface of the cable is not cleaned, the insulation performance of the cable will be reduced, the risk of leakage or short circuit will be increased, and the adhesion between the cable and the insulating tape will be affected, causing the tape to be detached or displaced.

[0050] When repairing a cable, the present invention drives the telescopic rod 2 to adjust its length through the fixing rod 11, so that the telescopic rod 2 drives the support frame 1 to slide into the ravine, and at the same time, the support frame 1 drives the mounting block 3 to move downward. During the downward movement of the mounting block 3, the fixing column 403 is driven to move downward, and at the same time, the fixing column 403 pushes the first clamping jaw 401 and the second clamping jaw 402 to contact the upper surface of the cable. As the fixing rod 11 pushes the telescopic rod 2 to continue to move downward, the first clamping jaw 401 and the second clamping jaw 402 are affected by the thrust of the support frame 1 after contacting the upper surface of the cable, and the first clamping jaw 401 and the second clamping jaw 402 rotate around the fixing column 403, and at the same time, the torsion spring 405 in the inner cavity of the rotating groove 406 is twisted to rotate and open, thereby sheathing the cable. After the first clamping jaw 401 and the second clamping jaw 402 have covered the cable, the torsion spring 405 in the inner cavity of the rotating groove 406 is reset, and the first clamping jaw 401 and the second clamping jaw 402 are twisted to reset again, and then the piston rod is driven to insert into the limiting plug hole between the mounting block 3 and the first clamping jaw 401 by starting the two-way push rod 407, so as to limit the first clamping jaw 401 and the second clamping jaw 402, and prevent the first clamping jaw 401 and the second clamping jaw 402 from being unhooked when the cable is lifted, and avoid the existing cable repair device in the process of repairing the cable, requiring the operator to install and fix the clamp outside the cable, and then use the clamp to lift the cable for repair work, and in the process of fixing the clamp outside the cable, if the repaired cable When the cable leaks electricity, the operator is prone to safety hazards such as electric shock. After the first clamp 401 and the second clamp 402 clamp the cable, they drive the telescopic rod 2 to move upward, thereby driving the support frame 1 and the mounting block 3 to move upward, and at the same time driving the fixed column 403 to move upward. During the upward movement of the fixed column 403, the first clamp 401 and the second clamp 402 will be driven to lift the cable and move synchronously, thereby lifting the cable away from the ground or puddle, and then the cleaning cylinder 7 is driven to rotate around the cable, and the cleaning cylinder 7 cleans the dirt on the surface of the cable. In the process of rotating around the cable, the cleaning cylinder 7 drives the slider 901 to move back and forth in the inner cavity of the cleaning cylinder 7, so that the slider 901 drives the support plate 901. The operator installs the insulating rubber roller 16 that meets the model of the cable to be repaired between the two clamping blocks 903 in advance, and then the clamping block 903 is spirally wound around the surface of the cable as the slider 901 moves synchronously, so that a part of the insulating tape wound on the surface of the cable can be overlapped, to prevent water seepage after the cable is repaired and buried underground. This solves the problem that when a cable repair device is used to lift the cable for repair, a plurality of combined insulating rubber rollers are used to simultaneously wrap around the repaired part of the cable, resulting in the insulating tapes released by the insulating rubber rollers not being overlapped and wound around the outside of the cable, causing gaps between the insulating tapes, and the possibility of failure due to water accumulation in the later stage.

[0051] like Figure 1 , Figure 2 and Figure 6 As shown, a support slide 905 is fixedly connected to the inner cavity of the support plate 902, and two clamping blocks 903 are slidably connected to the support slide 905. A tension spring 904 is fixedly connected to one side of the inner cavity of the support plate 902, and the tension spring 904 is fixedly connected to the clamping block 903 at one end away from the inner cavity of the support plate 902. A transmission shaft 906 is rotatably connected between the two clamping blocks 903, and the transmission shaft 906 is used to clamp the insulating rubber roller 16.

[0052] Specifically, when installing the insulating rubber roller 16, the two clamping blocks 903 are pushed to pull the tension spring 904 to move away from each other, and then the insulating rubber roller 16 is placed between the two clamping blocks 903. At the same time, the tension spring 904 is used to pull the two clamping blocks 903 to reset, and then the two clamping blocks 903 drive the transmission shaft 906 to move closer to each other, so that the transmission shaft 906 is inserted into the inner cavity of the insulating rubber roller 16 and supports the insulating rubber roller 16. At the same time, the two clamping blocks 903 limit the two ends of the insulating rubber roller 16, thereby ensuring the stability of the insulating rubber roller 16 when discharging the insulating tape, thereby improving the cable repair effect.

[0053] like Figure 1 , Figure 2 and Figure 7 As shown, a rotating groove 406 is provided inside the first clamping jaw 401 and the second clamping jaw 402, a fixed column 403 is located outside the inner cavity of the rotating groove 406 and is fixedly connected to two fixed disks 404, and a torsion spring 405 is fixedly connected to one end face of each fixed disk 404, and the torsion spring 405 is fixedly connected to the rotating groove 406 at one end away from the fixed disk 404, a two-way push rod 407 is provided inside the upper end of the second clamping jaw 402, and a limited position socket is provided between the mounting block 3 and the first clamping jaw 401.

[0054] Specifically, when the first clamping jaw 401 and the second clamping jaw 402 are used to clamp the cable, the torsion spring 405 in the inner cavity of the rotating groove 406 is reset, and the first clamping jaw 401 and the second clamping jaw 402 are twisted to reset again, and then the piston rod is driven to insert into the limiting plug hole between the mounting block 3 and the first clamping jaw 401 by starting the two-way push rod 407, thereby limiting the first clamping jaw 401 and the second clamping jaw 402 to prevent the first clamping jaw 401 and the second clamping jaw 402 from being unhooked when the cable is lifted, and at the same time, it can avoid the trouble of the operator manually operating the fixing jaws, thereby solving the problem that in the process of lifting and repairing the cable with the existing cable repair device, the operator needs to install and fix the clamps on the outside of the cable, and then use the clamps to lift the cable for repair work. In the process of fixing the clamps on the outside of the cable, if the repaired cable leaks electricity, the operator is prone to safety hazards such as electric shock.

[0055] like Figure 1 , Figures 3 to 5 As shown, a servo motor 25 is provided in the inner cavity of the fixed block 24, and the output shaft of the servo motor 25 passes through the semicircular fixed frame 5, and a main gear 20 is fixedly connected to one end of the inner cavity of the T-shaped limit groove 19, and a groove 18 is provided on one end surface of the semicircular rotating frame 6, and a semicircular gear ring is provided on one side wall of the groove 18, and the main gear 20 is meshed with the semicircular gear ring.

[0056] Specifically, when the cable is lifted and repaired, the servo motor 25 is started to drive the main gear 20 to rotate, and at the same time, the main gear 20 engages the transmission semicircular ring gear to drive the semicircular rotating frame 6 to rotate, and then the semicircular rotating frame 6 rotates in a circular shape in the inner cavity of the T-shaped limit groove 19. During the circular rotation of the semicircular rotating frame 6, the cleaning cylinder 7 is driven to move synchronously, and then the cleaning cylinder 7 rotates in a circular shape around the cable, and then the insulating rubber roller 16 is driven to clean and repair the cable, thereby improving the cable repair efficiency.

[0057] like Figures 3 to 5 As shown, the output shaft of the servo motor 25 is located at one end of the inner cavity of the T-shaped limit groove 19 and is externally connected to two belts 23 for transmission, and one end of the two belts 23 is rotatably connected to the inner cavity with a driven gear 22, and the driven gear 22 is rotatably connected to the bottom of the inner cavity of the T-shaped limit groove 19.

[0058] Specifically, during the process of lifting and repairing the cable, the main gear 20 is driven to rotate by the servo motor 25, and at the same time, the main gear 20 engages with the semicircular gear ring to drive the semicircular rotating frame 6 to rotate, and then the output shaft of the servo motor 25 drives the two belts 23 to rotate at the same time, and the two belts 23 drive the two driven gears 22 to rotate, and then the semicircular rotating frame 6 can always be driven in the inner cavity of the T-shaped limit groove 19, thereby improving the efficiency and stability of the cable repair work.

[0059] like Figure 4 As shown, four limiting wheels 21 are symmetrically arranged in the inner cavity of the T-shaped limiting groove 19, and every two limiting wheels 21 form a group, which are used to limit the transmission of the belt 23.

[0060] Specifically, during the rotation of the driven gear 22 driven by the belt 23, the belt 23 is supported and limited by four limiting wheels 21 to prevent the belt 23 from loosening, thereby improving the transmission efficiency and the rotation stability of the semicircular rotating frame 6, thereby repairing the cable.

[0061] Embodiment 2

[0062] like Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0063] like Figure 1 and Figure 8As shown, the upper end of the fixed rod 11 is rotatably connected to an H-shaped rotating block 14, and the inner cavity of the H-shaped rotating block 14 is rotatably connected to a rotating frame 12. Buckles 13 are symmetrically arranged on both sides of the fixed rod 11, and the buckles 13 are used to snap on and accommodate the rotating frame 12. The inner cavity of the fixed rod 11 is rotatably connected to a threaded rod 26, and the threaded rod 26 is threadedly connected to the telescopic rod 2. One end of the threaded rod 26 passes through the fixed rod 11 and the H-shaped rotating block 14 and is fixedly connected to a crank 15.

[0064] Specifically, after the cable is clamped and fixed, the rotating frame 12 is taken out from the inner cavity of the buckle 13, and the rotating frame 12 is turned 90 degrees in the inner cavity of the H-shaped rotating block 14. At this time, the H-shaped rotating block 14 will resist the rotating frame 12, so that the rotating frame 12 cannot be turned over. Then the operator rotates the H-shaped rotating block 14 to adjust the angle according to the position of the gully, so that the rotating frame 12 overlaps the two ends of the gully, and at the same time rotates the crank 15, and the crank 15 drives the threaded rod 26 to rotate. During the rotation process, the threaded rod 26 will threadably drive the telescopic rod 2 to move upward, and then the telescopic rod 2 slides into the fixed rod 11, while the telescopic rod 2 drives the support frame 1 to move upward, and the support frame 1 drives the mounting block 3 and the fixed column 403 to move upward synchronously, and then the fixed column 403 drives the first clamping claw 401 and the second clamping claw 402 to lift the cable and move it upward, so as to prevent the water or mud inside the gully from affecting the repair work of the cable, thereby solving the problem that when the existing cable repair device lifts and repairs the cable, if the angle position of the gully excavation is different, and the support lifting mechanism cannot be adjusted according to the gully spacing or position, it will cause the support lifting mechanism to be unable to contact and support the ground, thereby affecting the lifting effect of the cable.

[0065] like Figure 2 and Figure 6 As shown, a driving motor 10 is arranged on one side of the inner cavity of the cleaning cylinder 7, the driving motor 10 is fixedly connected to the screw 17 through the output shaft, the slider 901 is threadedly connected to the screw 17, brushes are evenly arranged on the outside of the cleaning cylinder 7, a scraper 8 is fixedly connected to the outside of the cleaning cylinder 7, and the scraper 8 is made of hard rubber.

[0066] Specifically, when the semicircular rotating frame 6 drives the cleaning cylinder 7 to rotate in a circle around the cable, the dust and dirt on the surface of the cable are cleaned by the brush outside the cleaning cylinder 7, and some dirt that is difficult to clean is scraped off by the scraper 8. Since the scraper 8 is arranged in the middle of the brush, after the scraper 8 scrapes off the dirt on the surface of the cable, the brush can be used to clean the surface of the cable again, thereby improving the cleanliness of the cable surface, improving the adhesion effect of the insulating tape, and increasing the repair efficiency. Moreover, when the insulating tape is spirally wound on the surface of the cable, as the cleaning cylinder 7 rotates, the scraper 8 will scrape the adhered and wound insulating tape, so that the insulating tape can fit more closely to the surface of the cable, reduce the gap between the tape and the cable, thereby improving the insulation performance and reducing the risk of current leakage.

[0067] A cable repair method, applied to a cable repair device, comprises the following steps:

[0068] S1. Confirm the location where the underground cables are damaged, and use excavation equipment to dig a trench in the ground to expose the cables;

[0069] S2, clamping the cable with the clamping hanger, and driving the clamping hanger to lift the damaged part of the cable away from the ground;

[0070] S3. The repair personnel then clean the dirt and dust on the outer surface of the cable, and then use an insulating rubber roller to wrap the insulating tape around the cable. The number of layers of the insulating tape must not be less than 3 layers. The dust-proof cable is buried underground and water vapor penetrates. After the winding is completed, the voltage detection equipment is used to detect the damaged part of the cable to see if there is any leakage, thereby completing the cable repair work.

[0071] Preferably, the clamping mechanism used in the clamping hanger is made of insulating material to prevent leakage of the cable due to damage when the cable is clamped and lifted, causing the cable to conduct electricity through the clamping mechanism and posing a safety hazard to the operator. The insulating rubber roller selects insulating tape with corresponding dielectric strength according to the model of the cable to be repaired to prevent the voltage of the repaired cable from penetrating the insulating tape.

[0072] Working principle: when repairing the cable, the telescopic rod 2 is driven by the fixed rod 11 to adjust the length, so that the telescopic rod 2 drives the support frame 1 to slide into the ravine, and at the same time, the support frame 1 drives the mounting block 3 to move downward, and during the downward movement of the mounting block 3, the fixed column 403 is driven to move downward, and at the same time, the fixed column 403 pushes the first clamping jaw 401 and the second clamping jaw 402 to contact the upper surface of the cable, and as the fixed rod 11 pushes the telescopic rod 2 to move downward continuously, the first clamping jaw 401 and the second clamping jaw 402 are affected by the thrust of the support frame 1 after contacting the upper surface of the cable, and the first clamping jaw 401 and the second clamping jaw 402 surround the cable. The fixed column 403 rotates, and at the same time, the torsion spring 405 in the inner cavity of the rotating groove 406 is twisted to rotate and open, so as to cover the cable. After the first clamping jaw 401 and the second clamping jaw 402 cover the cable, the torsion spring 405 in the inner cavity of the rotating groove 406 is reset, and at the same time, the first clamping jaw 401 and the second clamping jaw 402 are twisted to reset again, and then the two-way push rod 407 is started to drive the piston rod to insert into the limiting plug hole between the mounting block 3 and the first clamping jaw 401, so as to limit the first clamping jaw 401 and the second clamping jaw 402, and prevent the first clamping jaw 401 and the second clamping jaw 402 from being unhooked when the cable is hoisted;

[0073] After the first clamp 401 and the second clamp 402 clamp the cable, the rotating frame 12 is taken out from the inner cavity of the buckle 13, and the rotating frame 12 is turned ninety degrees in the inner cavity of the H-shaped rotating block 14. At this time, the H-shaped rotating block 14 will resist the rotating frame 12, so that the rotating frame 12 cannot be turned over. Then the operator rotates the H-shaped rotating block 14 to adjust the angle according to the position of the gully, so that the rotating frame 12 overlaps the two ends of the gully, and at the same time rotates the crank 15, and the crank 15 drives the threaded rod 26 to rotate. During the rotation process, the threaded rod 26 will threadably drive the telescopic rod 2 to move upward, and then the telescopic rod 2 slides into the inner cavity of the fixed rod 11 for storage. At the same time, the telescopic rod 2 drives the support frame 1 to move upward, and the support frame 1 drives the mounting block 3 and the fixed column 403 to move upward synchronously, and then the fixed column 403 drives the first clamp 401 and the second clamp 402 to lift the cable and move it upward;

[0074] The servo motor 25 is started to drive the main gear 20 to rotate, and the main gear 20 meshes with the transmission semicircular gear ring to drive the semicircular rotating frame 6 to rotate, and then the semicircular rotating frame 6 is made to rotate in a circular manner in the inner cavity of the T-shaped limit groove 19. During the circular rotation of the semicircular rotating frame 6, the cleaning cylinder 7 is driven to move synchronously, and then the cleaning cylinder 7 is made to rotate in a circular manner around the cable, and then the insulating rubber roller 16 is driven to clean and repair the cable. In the process of the cleaning cylinder 7 rotating around the cable, the slider 901 is driven to move back and forth in the inner cavity of the cleaning cylinder 7, so that the slider 901 drives the support plate 901 to move, and at the same time drives the two clamping blocks 903 to move synchronously, and the operator pre-installs the insulating rubber roller 16 that meets the model of the repaired cable between the two clamping blocks 903, and then the clamping block 903 is synchronously moved with the slider 901 to spirally wind the cable surface, so that a part of the insulating tape wound on the cable surface can be overlapped, so as to prevent water seepage after the cable is repaired and buried underground in the later stage;

[0075] When the semicircular rotating frame 6 drives the cleaning cylinder 7 to rotate in a circle around the cable, the dust and dirt on the surface of the cable are cleaned by the brush outside the cleaning cylinder 7, and some dirt that is difficult to clean is scraped off by the scraper 8. Since the scraper 8 is arranged in the middle of the brush, after the scraper 8 scrapes off the dirt on the surface of the cable, the brush can be used to clean the surface of the cable again, thereby improving the cleanliness of the cable surface, improving the adhesion effect of the insulating tape, and increasing the repair efficiency. Moreover, when the insulating tape is spirally wound on the surface of the cable, as the cleaning cylinder 7 rotates, the scraper 8 will scrape the adhered and wound insulating tape, so that the insulating tape can fit more closely to the surface of the cable, reduce the gap between the tape and the cable, thereby improving the insulation performance and reducing the risk of current leakage.
