Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, specifically to an overhead cable maintenance device for power maintenance. Background Technology

[0002] Overhead cables are mainly used to transmit electrical energy or signals in the air. They are an important infrastructure in the fields of power and communication. Compared with underground cables, overhead cables do not require trenching, have a shorter construction period, and are easier to maintain. As the main channel for power transmission, the stability of overhead cables is directly related to the reliability of power supply. Overhead cables are exposed to the outdoor environment for a long time and are susceptible to corrosion from wind, rain, sun, salt spray, and other factors, which can damage the cables and affect their normal power transmission. Therefore, regular inspection and maintenance of the cables are necessary.

[0003] Currently, most overhead cables are laid on both sides of the road, and there are often more than one cable, with a certain distance between them. During the maintenance process, traditional maintenance platforms can usually only be set up on flat surfaces, and can only reach one or a part of the cable. It is difficult to reach the cables far from the roadside. If these cables need to be maintained, it is often necessary to rebuild the maintenance platform or move the existing platform. However, due to the presence of green belts, buildings or other obstacles around the road, the presence of these objects makes it difficult to build the maintenance platform smoothly. In addition, rebuilding the platform requires a lot of time and manpower, which not only increases the maintenance cost but also prolongs the maintenance time.

[0004] Furthermore, existing cable inspection methods mostly involve manual handheld inspection instruments that are used to inspect the cable step by step. This is not only slow but also has a limited inspection range, making it difficult to conduct a comprehensive inspection of the cable and prone to missed inspections. In addition, during the inspection and maintenance of cables, there is a lack of effective fixation for the cables. The cables are in an overhead state and are prone to shaking under the action of external forces (such as wind), which affects the inspection and maintenance work and increases the difficulty of inspection and maintenance.

[0005] Therefore, those skilled in the art have provided an overhead cable maintenance device for power line repair to solve the problems mentioned in the background art. Summary of the Invention

[0006] The purpose of this invention is to provide an overhead cable maintenance device for power line repair, so as to solve the problems mentioned in the background art.

[0022] A push plate is also fixedly connected to the multiple sets of connecting rods located inside the storage cavity, and the push plate slides inside the storage cavity.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. When in use, the drive cylinder moves the sliding adjustment frame upward, and the connecting plate pushes multiple sets of first and second support plates to flip, which can realize flexible adjustment of the height of the maintenance platform. Maintenance personnel can accurately control the maintenance platform to rise to a suitable position according to the actual height of the cable, which is convenient for maintenance work. In addition, the two sets of auxiliary adjustment rods provide auxiliary support, which further enhances the overall stability of the equipment, keeps the maintenance platform stable during the rising process, and ensures the safety of maintenance personnel.

[0025] Meanwhile, the two sets of auxiliary adjustment rods, together with the base and support plate, form a stable triangular structure, which enhances the overall stability of the device. During maintenance, even if external interference or complex environment is encountered, the maintenance platform can be kept stable and does not shake, providing a safe and reliable working space for maintenance personnel, effectively avoiding safety accidents caused by platform shaking, and ensuring the personal safety of maintenance personnel.

[0026] 2. The auxiliary maintenance component in this invention further expands the scope of cable maintenance. Initially, the auxiliary maintenance platform is stored under the maintenance platform. When the sliding adjustment frame pushes the support plate to flip, it is driven by the drive rod to flip until it connects with the maintenance platform. Maintenance personnel can enter the auxiliary maintenance platform through the maintenance door to maintain the cables on the other side. Multiple cables can be maintained in one operation without frequent device movement or rebuilding of the maintenance platform, which greatly improves the efficiency of maintenance work.

[0027] 3. In this invention, after the maintenance personnel place the cable to be inspected on the placement frame, the cable is synchronously clamped by two sets of clamping plates, which can ensure the cable is stable and facilitate the maintenance personnel to carry out comprehensive and detailed maintenance work. It avoids the cable shaking from affecting the maintenance accuracy and provides convenient conditions for the maintenance personnel to carry out comprehensive and detailed maintenance.

[0028] Driven by the drive assembly, the detection ring moves along the cable. Multiple detectors within it can perform a comprehensive inspection of the cable. Before testing, a scraper can clean the cable surface to remove dust and dirt, making the test results more accurate. When the detector detects an abnormality in the cable, it can quickly control the guide wheel assembly to close, stopping the connecting ring from moving. The detection ring continues to move, triggering the push plate to squeeze the pigment into the delivery pipe and spray it out through the nozzle, accurately marking the abnormal area. This integrated design of detection and marking greatly improves maintenance efficiency, facilitates subsequent maintenance of abnormal areas, and reduces the possibility of missed detections and misjudgments.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0045] Example 1, please refer to Figure 1-13A cable overhead maintenance device for power maintenance includes a support 1. The four sides of the bottom of the support 1 are equipped with casters 11 for easy movement. The support 1 is equipped with a support component 2. The end of the support component 2 away from the support 1 is equipped with a maintenance platform 3 for easy maintenance of overhead cables. The maintenance platform 3 is also equipped with a cable maintenance component. The support component 2 is also hinged with an auxiliary maintenance component 4 for assisting the maintenance platform 3 in maintaining cables on the other side. The maintenance platform 3 is hinged with a maintenance door 31 on the side close to the auxiliary maintenance component 4. The cable maintenance component includes a cable limiting component 5 fixedly connected to the maintenance platform 3 and two sets of placement components 6 set on both sides of the cable limiting component 5. The two sets of placement components 6 are each snapped with a detection component 7. The detection component 7 is also equipped with a pre-cleaning component 8 for cleaning the surface of the cable.

[0046] When in use, first move the entire device to the underside of the cable to be repaired by using the moving wheels 11 on the bracket 1 and fix it. After fixing it, start the support component 2, so that the support component 2 drives the repair platform 3 to rise until the repair platform 3 rises to the height of the cable.

[0047] Once the maintenance platform 3 reaches the height of the cable, the support component 2 is closed to fix it in place. Maintenance personnel can then access the maintenance platform 3 through the support component 2 to carry out maintenance work.

[0048] As the support component 2 moves the maintenance platform 3 upward, it can simultaneously push the auxiliary maintenance component 4 to flip, so that the auxiliary maintenance component 4 is connected to the maintenance platform 3, making it convenient for maintenance personnel to enter the auxiliary maintenance component 4 through the maintenance door 31 to carry out maintenance work on other cables.

[0049] Example 2, please refer to Figure 1-4 The support assembly 2 includes two sets of first support plates 21 and two sets of second support plates 22. The sides of both sets of first support plates 21 and second support plates 22 closest to the bracket 1 are hinged to the bracket 1. The other ends of both sets of first support plates 21 and second support plates 22 are hinged to the maintenance platform 3. Multiple sets of footboards 23 are hinged between the two sets of first support plates 21 and the two sets of second support plates 22. Multiple sets of support frames 2 are also fixedly connected to the sides of the two sets of second support plates 22 away from the first support plates 21 for fixing the two sets of second support plates 22. 9. The support assembly 2 also includes a drive cylinder 24 fixedly connected to the bracket 1, and the drive cylinder 24 is located below the multiple sets of first support plates 21 and second support plates 22. The output end of the drive cylinder 24 is hinged to a first connecting shaft 25, and a sliding adjustment frame 26 is fixedly connected to the first connecting shaft 25. The bottom of the two sets of second support plates 22 is also fixedly connected to a slide rail 27 for sliding the sliding adjustment frame 26. The bracket 1 is also hinged to two sets of auxiliary adjustment rods 28, and the other end of the two sets of auxiliary adjustment rods 28 is hinged to the second support plate 22.

[0050] Specifically, after the device is fixed in place, the drive cylinder 24 is activated. The output end of the drive cylinder 24 moves upward through the first connecting shaft 25 and the sliding adjustment frame 26, causing the sliding adjustment frame 26 to slide upward along the slide rail 27. When the sliding adjustment frame 26 moves upward, it pushes multiple sets of first support plates 21 and second support plates 22 to flip, increasing the angle between the first support plates 21 and second support plates 22 and the bracket 1, thereby increasing the height of the first support plates 21 and second support plates 22, driving the maintenance platform 3 to rise until the maintenance platform 3 rises to the height of the cable.

[0051] Once the maintenance platform 3 reaches the height of the cable, the drive cylinder 24 is deactivated, fixing the support assembly 2. With the auxiliary support of two sets of auxiliary adjustment rods 28, the overall device becomes more stable. Maintenance personnel can then access the maintenance platform 3 via multiple sets of pedals 23 to carry out maintenance work.

[0052] Example 3, please refer to Figure 1-4 The auxiliary maintenance assembly 4 includes an auxiliary maintenance platform 41 hinged between two sets of auxiliary adjustment rods 28. Both sides of the auxiliary maintenance platform 41 are fixedly connected to third connecting shafts 44. The other ends of the two sets of third connecting shafts 44 are respectively hinged to the two sets of auxiliary adjustment rods 28. Both sides of the auxiliary maintenance platform 41 are provided with drive rods 42. Both ends of the two sets of drive rods 42 are fixedly connected to second connecting shafts 43. The two sets of second connecting shafts 43 near the auxiliary maintenance platform 41 are hinged to the outer wall of the auxiliary maintenance platform 41. The two sets of second connecting shafts 43 near the sliding adjustment frame 26 are respectively hinged to both sides of the sliding adjustment frame 26.

[0053] Specifically, initially, the auxiliary inspection platform 41 is stored under the inspection platform 3. When the sliding adjustment frame 26 slides and pushes the first support plate 21 and the second support plate 22 to flip, the two sets of second connecting shafts 43 on both sides of the sliding adjustment frame 26 simultaneously push the drive rod 42, causing the drive rod 42 to drive the auxiliary inspection platform 41 to flip and connect with the inspection platform 3. During maintenance, maintenance personnel can enter the auxiliary inspection platform 41 through the maintenance door 31 on the inspection platform 3 to facilitate the maintenance of the cables on the other side.

[0054] After the maintenance work is completed, the drive cylinder 24 drives the sliding adjustment frame 26 to slide down along the slide rail 27, so that the first support plate 21 and the second support plate 22 are retracted. At the same time, the sliding adjustment frame 26 pulls the auxiliary maintenance platform 41 to flip through the two sets of second connecting shafts 43 and drive rods 42, so that the auxiliary maintenance platform 41 can be flipped again to be retracted under the maintenance platform 3.

[0055] Example 4, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 10The cable limiting component 5 includes a placement frame 51 fixedly connected to the maintenance platform 3. Two sets of fixing frames 52 are fixedly connected inside the placement frame 51. Two sets of synchronous gears 53 are rotatably connected in each set of fixing frames 52. The two sets of synchronous gears 53 located in the same set of fixing frames 52 mesh with each other. A drive motor is fixedly connected in one set of fixing frames 52. The output end of the drive motor is fixed to one set of synchronous gears 53. A first transmission link 54 is fixedly connected to each set of synchronous gears 53. Multiple sets of second transmission links 55 are hinged to the two sets of fixing frames 52. A clamping plate 56 is hinged to the other end of each set of first transmission links 54 and the adjacent second transmission link 55. A transmission rod 57 is fixedly connected to the synchronous gear 53 near the drive motor. The other end of the transmission rod 57 extends into another set of fixing frames 52. The extended end of the transmission rod 57 is fixed to one set of synchronous gears 53 in the fixing frame 52.

[0056] When inspecting cables, once the maintenance personnel arrive at the maintenance platform 3, they first place the cable to be inspected on the placement frame 51, positioning it between multiple sets of clamping plates 56. They then start the drive motor inside the fixing frame 52, causing one set of synchronous gears 53 to rotate. Since the two sets of synchronous gears 53 are hinged together, the other set of synchronous gears 53 also rotates synchronously. The rotation of the two sets of synchronous gears 53 drives the first transmission link 54 and the second transmission link 55 to move, causing the clamping plates 56 on the same fixing frame 52 to move closer to each other, clamping and fixing the cable. Simultaneously, the synchronous gears 53 in the other fixing frame 52 rotate synchronously under the drive of the transmission rod 57, causing the two sets of clamping plates 56 on the other fixing frame 52 to clamp the cable synchronously, fixing the cable located on the placement frame 51, facilitating comprehensive inspection by the maintenance personnel.

[0057] Example 5, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11The placement component 6 includes a fixed box 61 fixedly connected to the maintenance platform 3. A fixed frame 62 is fixedly connected to the side of the fixed box 61 away from the maintenance platform 3. The detection component 7 is snapped onto the fixed frame 62. A winding drum 63 is also rotatably connected inside the fixed box 61. A wire 64 is wound on the winding drum 63. Both ends of the wire 64 pass through to the outside of the fixed box 61. A receiver is fixedly connected to one end of the wire 64 and is set on the maintenance platform 3. The other end of the wire 64 is connected to the detection component 7 on the placement component 6. Synchronous pulleys 65 are also fixedly connected to the winding drums 63 in both fixed boxes 61. A synchronous belt 66 is sleeved between the two sets of synchronous pulleys 65. The two sets of synchronous pulleys 65 are connected by transmission through the synchronous belt 66. A servo motor is also fixedly connected inside the maintenance platform 3, and the output end of the servo motor is fixed to one of the sets of synchronous pulleys 65.

[0058] During testing, the testing component 7 is first removed from the fixed frame 62 and fixed to the cable. As the testing component 7 moves along the cable, the servo motor in the maintenance platform 3 is started simultaneously. The servo motor drives one of the synchronous pulleys 65 to rotate and drives the other synchronous pulley 65 to rotate through the synchronous belt 66. The two sets of synchronous pulleys 65 rotate at the same time, causing the two sets of winding drums 63 to rotate at the same time, so that the wire 64 can extend along with the movement of the testing component 7, maintaining the smooth flow of the signal.

[0059] Example 6, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13The detection component 7 includes a detection ring 71, which is snapped onto the fixed frame 62. A pre-cleaning component 8 is slidably connected to the detection ring 71 on the side away from the maintenance platform 3. Multiple sets of drive components are fixedly connected to the inner wall of the detection ring 71. Each drive component includes a fixed cylinder 72 fixedly connected to the inner wall of the detection ring 71. A sliding cylinder 73 is slidably connected to each fixed cylinder 72. An adjusting spring 74 is fixedly connected to the bottom of each sliding cylinder 73. The other ends of the multiple adjusting springs 74 are fixedly connected to adjacent fixed cylinders 72. A drive wheel 75 is fixedly connected to the top of each sliding cylinder 73. Multiple sets of detectors 76 are fixedly connected to the inner wall of the ring 71, and the signal output terminals of the multiple sets of detectors 76 are all connected to the wires 64. A marking assembly for marking the cable is also fixedly connected to the side of the detection ring 71 near the maintenance platform 3. The marking assembly includes a delivery pipe 78 fixedly connected to the detection ring 71. A storage cavity 77 for storing pigment is opened in the inner wall of the detection ring 71, and the storage cavity 77 is connected to the inside of the delivery pipe 78. Multiple sets of spray holes 79 for spraying pigment are opened on the delivery pipe 78. A sealing plate is fixedly connected to each set of spray holes 79, and a nozzle is opened on the sealing plate.

[0060] In use, first open the detection ring 71, put the detection ring 71 on the cable, adjust the position of the detection ring 71 so that the delivery tube 78 and the pre-cleaning component 8 are above the cable, and fix the opening of the detection ring 71 with bolts. After fixing, start the multiple sets of drive components and the pre-cleaning component 8 inside the detection ring 71. The drive components rotate and drive the detection ring 71 to move along the cable. The cable is inspected by the multiple sets of detectors 76 inside the detection ring 71. At the same time, before the detectors 76 check, the pre-cleaning component 8 cleans the surface of the cable to make the inspection results more accurate.

[0061] When an abnormality is detected, the receiver controls the pre-cleaning component 8 to stop immediately. At this time, the detection ring 71 continues to move under the drive of the drive component, so that the detection ring 71 inserts into the pre-cleaning component 8. The pre-cleaning component 8 squeezes out the pigment in the storage cavity 77 and sprays it out through the opening on the sealing plate. After spraying out, the pre-cleaning component 8 starts to move synchronously with the detection ring 71 and continues to inspect the cable.

[0062] The movement of the detection ring 71 by the drive component can be achieved by setting a drive motor on the drive wheel 75 to drive the drive wheel 75 to move, so that the drive wheel 75 rotates along the cable. This can be easily achieved by those skilled in the art with existing technology, and will not be described in detail here.

[0063] Example 7, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 11 , Figure 12 and Figure 13 The pre-cleaning component 8 includes multiple sets of connecting rods 81 slidably connected to the detection ring 71. The other ends of the multiple sets of connecting rods 81 are fixedly connected to two sets of connecting rings 82. Multiple sets of guide wheel sets 87 with the same structure as the transmission component on the detection ring 71 are fixedly connected to the inner walls of the two sets of connecting rings 82. A scraper 85 is also provided on the upper connecting ring 82, and the scraper 85 is in contact with the outer wall of the cable. Multiple sets of mounting slots 84 are also opened on the outer wall of the upper connecting ring 82. Multiple sets of mounting blocks 86 are fixedly connected to the side of the scraper 85 near the connecting ring 82. The multiple sets of mounting blocks 86 are respectively snapped into the adjacent mounting slots 84. A pusher plate 83 is also fixedly connected to the multiple sets of connecting rods 81 located in the storage cavity 77, and the pusher plate 83 slides in the storage cavity 77.

[0064] Before use, first select a suitable scraper 85 according to the diameter of the cable. Connect the scraper 85 to the connecting ring 82 through the mounting block 86 on the scraper 85. After connecting the detection ring 71 to the cable, the scraper 85 will contact the outer wall of the cable at the same time. As the detection ring 71 moves along the cable, the scraper 85 will first remove foreign objects on the cable to avoid foreign objects affecting the detection data.

[0065] During the cable inspection process of the moving detection ring 71, when the detector 76 detects abnormalities such as damage, aging, or deformation on the cable, the detector 76 transmits a signal to the receiver through the wire 64, causing the receiver to send a signal to close the multiple sets of guide wheels 87 on the connecting ring 82, thus stopping the movement of the connecting ring 82. When the connecting ring 82 stops, the detection ring 71 continues to move, causing the connecting rod 81 to extend into the storage cavity 77. The pushing plate 83 on the other end of the connecting rod 81 slides in the storage cavity 77, squeezing the pigment in the storage cavity 77 into the delivery pipe 78 and spraying it out through the spray hole 79 for marking, which facilitates subsequent maintenance.

[0066] The working principle of this invention is:

[0067] In use, first move the entire device under the cable to be repaired and fix it. After fixing it, start the drive cylinder 24. The output end of the drive cylinder 24 drives the sliding adjustment frame 26 to move upward. When the sliding adjustment frame 26 moves upward, it pushes multiple sets of first support plates 21 and second support plates 22 to flip, so that the angle between the first support plates 21 and second support plates 22 and the bracket 1 increases, thereby increasing the height of the first support plates 21 and second support plates 22, driving the repair platform 3 to rise until the repair platform 3 is raised to the height of the cable. Then, turn off the drive cylinder 24 to fix the support assembly 2. With the auxiliary support of two sets of auxiliary adjustment rods 28, the entire device becomes more stable. Repair personnel can reach the repair platform 3 through multiple sets of pedals 23 to carry out repair work.

[0068] When maintenance personnel arrive at maintenance platform 3, they first place the cable to be inspected on placement frame 51 and start the drive motor in the fixing frame 52. The drive motor drives one set of synchronous gears 53 to rotate. Through the hinge of the two sets of synchronous gears 53, the other set of synchronous gears 53 also rotates synchronously, causing the clamping plates 56 on the same fixing frame 52 to move towards each other and clamp and fix the cable. The synchronous gears 53 in the other set of fixing frames 52 rotate synchronously under the drive of transmission rod 57, causing the two sets of clamping plates 56 on the other set of fixing frames 52 to clamp the cable synchronously and fix the cable located on placement frame 51, making it convenient for maintenance personnel to carry out comprehensive inspection.

[0069] After the cable is fixed by multiple sets of clamping plates 56, the detection ring 71 is removed from the fixing frame 62. A suitable scraper 85 is selected according to the diameter of the cable. The scraper 85 is connected to the connecting ring 82 by the mounting block 86 on the scraper 85. The detection ring 71 is then placed on the cable. The position of the detection ring 71 is adjusted so that the conveying pipe 78 and the scraper 85 are above the cable. The opening of the detection ring 71 is then fixed with bolts. After it is fixed, the multiple sets of drive components and guide wheel group 87 inside the detection ring 71 are activated. The drive components rotate and drive the detection ring 71 to move along the cable. The cable is inspected by multiple sets of detectors 76 inside the detection ring 71. At the same time, before the detectors 76 inspect the cable, the scraper 85 cleans the surface of the cable to make the inspection results more accurate.

[0070] During the cable inspection process of the moving detection ring 71, when the detector 76 detects an abnormality in the cable, the detector 76 transmits a signal to the receiver through the wire 64. The receiver controls the multiple sets of guide wheels 87 on the connecting ring 82 to close, causing the connecting ring 82 to stop moving. When the connecting ring 82 stops, the detection ring 71 continues to move, causing the connecting rod 81 to extend into the storage cavity 77. The push plate 83 on the other end of the connecting rod 81 slides in the storage cavity 77, squeezing the pigment in the storage cavity 77 into the delivery pipe 78 and spraying it out through the spray hole 79 for marking, which facilitates subsequent maintenance. After the pigment is sprayed out for marking, the guide wheel set 87 starts to move synchronously with the detection ring 71 to continue inspecting the cable.

[0071] While the inspection ring 71 moves to inspect the cable, the maintenance personnel simultaneously use instruments such as multimeters and thermal imagers on the maintenance platform 3 to inspect the comprehensive performance of the cable. For example, they measure the resistance value of the cable conductor, evaluate the conductivity of the cable, ensure the power transmission efficiency, and use infrared thermometers and other equipment to detect the temperature of the cable connection points to determine whether there are problems such as overload or local overheating, and deal with them in time to prevent the fault from expanding.

[0072] Initially, the auxiliary inspection platform 41 is stored under the inspection platform 3. When the sliding adjustment frame 26 slides and pushes the first support plate 21 and the second support plate 22 to flip, the two sets of second connecting shafts 43 on both sides of the sliding adjustment frame 26 simultaneously push the drive rod 42, so that the drive rod 42 drives the auxiliary inspection platform 41 to flip and connect with the inspection platform 3. During subsequent maintenance, maintenance personnel can enter the auxiliary inspection platform 41 through the maintenance door 31 on the inspection platform 3 to facilitate the maintenance of the cables on the other side.

The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
