Description

Technical Field

[0001] The present invention relates to the technical field of cable surface repair, and particularly relates to an overhead insulated cable surface repair device. Background Art

[0002] For the damage of the insulating layer of overhead insulated cables caused by environmental factors (such as ultraviolet rays, weathering, chemical corrosion, etc.) or mechanical damage, the existing repair of insulated cables is mainly carried out manually, usually using insulating tapes or heat shrinkable tubes for wrapping. However, these methods have obvious deficiencies. First of all, these materials are prone to aging and falling off in the outdoor environment and cannot effectively protect the cables for a long time. Secondly, these repair methods often require manual operation, which is not only inefficient but also difficult to ensure the consistency of the repair quality. Finally, for high-altitude operations, the safety of this repair method also has certain potential hazards.

[0003] However, ordinary overhead insulated cable surface repair devices usually have some problems during daily use. With the development of technology, technicians in related fields have also carried out a lot of optimizations on the overhead insulated cable surface repair devices to solve some problems that different consumer groups care about. For more accurate comparison, for example, Chinese Patent No. CN108173176A discloses a repair device and a repair method for the aging of the insulating layer of high-altitude cables; it includes a housing and a rotating body rotatably sleeved in the housing; the rotating body is rotatably sleeved outside the high-altitude cable; the rotating body is driven to rotate by a motor fixedly arranged in the housing; a coating cavity is arranged in the middle of the housing and above the high-altitude cable; a waterproof insulating coating is filled in the coating cavity; a discharge port facing the high-altitude cable is opened at the bottom of the coating cavity; a solenoid valve for opening and closing the discharge port is arranged at the discharge port; a material extrusion device extrudes the waterproof insulating coating in the coating cavity from the discharge port; the surface of the rotating body in contact with the high-altitude cable is arranged sequentially along its length direction.

[0004] When in use, it has a propulsion part that makes the repair device move forward along the high-altitude cable by using the rotation of the rotating body, a rough grinding part, a fine grinding part and a precision grinding part that sequentially grind the insulating layer of the high-altitude cable by using the rotation of the rotating body, and a uniform spreading part that evenly spreads the waterproof insulating coating extruded from the discharge port on the surface of the high-altitude cable by using the rotation of the rotating body.

[0005] However, the above-mentioned prior art for the overhead insulated cable surface repair technology still has some deficiencies in the actual use process: 1. When the high-altitude cable is damaged, there will be dirt and loose materials at the damaged part. Therefore, before repairing the high-altitude cable, it needs to be cleaned. The above-mentioned prior art does not clean the high-altitude cable before repairing it. Therefore, after repairing the high-altitude cable, the dirt wrapped at the wrapped part affects the repair of the high-altitude cable by the waterproof insulating coating, resulting in the peeling off of the waterproof insulating coating, and thus frequent repairs are required.

[0006] 2. Although the above-mentioned prior art can repair the high-altitude cables through waterproof insulating coating, the waterproof insulating coating is only coated on the outer wall of the high-altitude cables, which is prone to cracking and aging after being exposed to high temperatures, thus becoming ineffective, causing the high-altitude cables to be damaged again, and the repair effect is poor.

Detailed implementation mode

[0035] The following is combined with the attached Figures 1-10 The embodiments of the present invention will be described in detail.

[0036] The embodiment of the present application discloses a surface repair device for overhead insulated cables. It should be noted that the surface repair device for overhead insulated cables in the present application is mainly applied in the process of repairing the surface of overhead insulated cables. In terms of technical effects, it can effectively clean the damaged parts of the cables, preventing dirt and loose materials from affecting subsequent repairs; especially during the repair of insulated cables, it can roll the insulating tape to ensure a better bonding effect between the insulating tape and the cable, thereby achieving a stable repair of the damaged parts of the cable; further, the surface repair device for overhead insulated cables can also automatically cut the insulating tape wound around the outer wall of the insulated cable, facilitating subsequent repair of the damaged parts at the lower end of the insulated cable, thereby realizing continuous repair of the insulated cable and improving the repair efficiency of the insulated cable. Embodiment 1:

[0037] Refer to Figure 1As shown in the figure, an overhead insulated cable surface repair device includes a support frame 1. A bidirectional motor 11 is installed in the middle of the support frame 1 through a motor mount. Arc-shaped plates 12 are connected to both sides of the support frame 1 in the length direction. Output shafts of the bidirectional motor 11 are both connected to transmission shafts 13. One ends of the two transmission shafts 13 far from the bidirectional motor 11 pass through the arc-shaped plates 12 and are respectively sleeved with transmission gears 14. Rotating components 2 that cooperate with the transmission gears 14 are installed on the opposite sides of the two arc-shaped plates 12; Two groups of runner supports 15 are installed at the bottom of the support frame 1. Each group of runner supports 15 has two and is symmetrically distributed along the width direction of the support frame 1. A rotating shaft 16 is rotatably connected between the two runner supports 15 in the same group. A moving wheel 17 is sleeved on the outer wall of the rotating shaft 16. The two rotating shafts 16 are connected by belt drive. A driving motor 18 is installed on the outer wall of any one of the runner supports 15 through a motor base. The output shaft of the driving motor 18 is connected to the rotating shaft 16 by belt drive. A cleaning component 3 for cleaning the outer wall of the cable is installed on the rotating component 2 on one side of the advancing direction of the moving wheel 17, and a winding component 4 for repairing the exposed surface of the cable is installed on the rotating component 2 on the side far from the advancing direction of the moving wheel 17.

[0038] In the specific implementation process, first, the device is erected on the surface of the insulated cable, so that the moving wheel 17 is clamped on the upper end of the insulated cable. Then, the driving motor 18 is started. The output shaft of the driving motor 18 drives the rotating shaft 16 and the moving wheel 17 connected to it to rotate. The rotating shaft 16 drives another rotating shaft 16 and the moving wheel 17 on its outer wall to rotate synchronously through belt drive, thereby driving the support frame 1, the rotating component 2, the cleaning component 3, and the winding component 4 to move synchronously; When moving to the damaged part of the insulated cable, the bidirectional motor 11 is started. The two output shafts of the bidirectional motor 11 drive the rotating component 2 to move circumferentially around the outer wall of the cable. At the same time, the rotating component 2 drives the cleaning component 3 to clean the damaged part of the cable, preventing dirt and loose materials in the damaged area from adhering to the outer wall of the cable and affecting the subsequent repair of the cable. After the cleaning is completed, the rotating component 2 drives the winding component 4 to repair the cable. The insulating tape is wound around the damaged area through the winding component 4 to ensure that the damaged area of the cable is completely covered, thereby realizing the rapid repair of the insulated cable.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in order to drive the cleaning assembly 3 and the winding assembly 4 to operate, based on this, a turnover assembly 2 is provided in this embodiment; specifically, the turnover assembly 2 includes a connecting rod 21 installed on the opposite sides of the two arc-shaped plates 12, the connecting rod 21 is connected to a support ring 22 on the side away from the arc-shaped plate 12, and the support ring 22 is provided with a T-shaped groove 23 on the side away from the connecting rod 21, and a T-shaped bar 24 is slidably connected in the T-shaped groove 23, and the T-shaped bar 24 is connected to a linkage gear ring 25 meshing with the transmission gear 14 on the side away from the arc-shaped plate 12. The turnover assembly 2 also includes a linkage shaft 26 rotatably connected to the opposite sides of the two arc-shaped plates 12, the outer wall of the linkage shaft 26 is sleeved with a linkage gear 27 meshing with the linkage gear ring 25, the transmission shaft 13 and the linkage shaft 26 are connected through a belt drive, and the bottom of the arc-shaped plate 12, the support ring 22 and the linkage gear ring 25 are all provided with a clearance groove 28 on the same axis, and the clearance groove 28 is connected with the middle of the arc-shaped plate 12, the support ring 22 and the linkage gear ring 25, and is used to sleeve the arc-shaped plate 12, the support ring 22 and the linkage gear ring 25 on the outside of the insulated cable.

[0040] Furthermore, in the present embodiment, two bending rods 181 corresponding to the moving wheels 17 are connected to both sides of the support frame 1 in the length direction, and a cross bar 182 is rotatably connected to the bottom of the bending rod 181 on either side, and two rotating brackets 183 are installed on the upper end of the cross bar 182, and a transfer shaft 184 is rotatably connected between the two rotating brackets 183, and a driving wheel 185 is sleeved on the outer wall of the transfer shaft 184, and a lock buckle 186 is connected between the bottom of the bending rod 181 on the other side and the cross bar 182, and the outer walls of the rotating shaft 16 and the transfer shaft 184 are sleeved with mutually meshing transfer gears 187.

[0041] In the specific implementation process, first open the lock 186, pull the cross bar 182, so that the cross bar 182 rotates downward along the hinge of the bending rod 181, and drives the rotating bracket 183, the transfer shaft 184, the driving wheel 185 and the lower transfer gear 187 to move synchronously, so as to open the bending rod 181 and the cross bar 182, and then move the device to above the insulated cable, and clamp the insulated cable under the moving wheel 17, pull the cross bar 182 upward to make the cross bar 182 rotate upward along the hinge of the bending rod 181, and make the cross bar 182 in a horizontal state, the two transfer gears 187 engage with each other, and the driving wheel 185 clamps with the bottom of the insulated cable, and then close the lock 186 to lock the cross bar 182 and the bending rod 181, so that the insulated cable is clamped by the moving wheel 17 and the driving wheel 185, which greatly increases the stability of the device.

[0042] In the process of setting up the device on the upper end of the insulated cable, the arc plate 12, the support ring 22 and the linkage gear ring 25 are sleeved on the outside of the insulated cable through the clearance groove 28, so that the moving wheel 17 is clamped on the outer wall of the insulated cable. When the moving wheel 17 drives the device to move to the damaged part of the insulated cable, the bidirectional motor 11 is started, and the two output shafts of the bidirectional motor 11 drive the transmission gear 14 and the transmission shaft 13 to rotate, and then the transmission gear 14 drives the linkage gear ring 25 to rotate. With the cooperation of the T-slot 23 and the T-bar 24, the linkage gear ring 25 rotates along the T-slot 23; at the same time, during the rotation of the transmission shaft 13, the linkage shaft 26 and the linkage gear 27 are driven to rotate synchronously, and the linkage gear 27 synchronously drives the linkage gear ring 25 to rotate, and the two linkage gear rings 25 respectively drive the cleaning component 3 and the winding component 4 to operate to clean and repair the insulated cable.

[0043] It should be noted that when the transmission gear 14 drives the linkage gear ring 25 to rotate to the clearance groove 28, the transmission gear 14 and the linkage gear ring 25 are no longer meshed, the linkage gear ring 25 is meshed with the linkage gear 27, and the linkage gear 27 drives the linkage gear ring 25 to continue to rotate, and then the linkage gear ring 25 resumes meshing with the transmission gear 14 and rotates in coordination. When the clearance groove 28 on the linkage gear ring 25 rotates to approach the linkage gear 27, the linkage gear 27 and the linkage gear ring 25 are no longer coordinated. At this time, the transmission gear 14 drives the linkage gear ring 25 to continue to rotate along the T-slot 23 and makes the linkage gear ring 25 mesh with the linkage gear 27 again, so that the linkage gear ring 25 can continue to rotate and drive the cleaning component 3 and the winding component 4 to operate, thereby greatly improving the repair efficiency of the device.

[0044] Reference Figure 1 and Figure 5 As shown, in order to clean the dirt on the damaged part of the insulated cable, a cleaning component 3 is provided in this embodiment; specifically, the cleaning component 3 includes two swing rods 31 installed on the linkage gear ring 25 away from the winding component 4, the two swing rods 31 are hinged to the linkage gear ring 25 away from the winding component 4, and the two swing rods 31 are symmetrically distributed along the axis of the linkage gear ring 25, a bending plate 32 is hinged on the side of the swing rod 31 away from the linkage gear ring 25, a plurality of cleaning cilia 33 are installed on the bending plate 32 close to the insulating cable, a torsion spring is installed at the hinge between the swing rod 31 and the linkage gear ring 25, a guide plate 34 gradually inclined toward the side away from the insulating cable is installed at the bottom of the bending plate 32, and balance blocks 35 are connected to both ends of the bottom of the arc plate 12.

[0045] It should be noted that the torsion spring always applies a torsion force to the swing rod 31 toward the side close to the insulating cable, so that the cleaning cilia 33 on the bending plate 32 always fit with the insulating cable, thereby enhancing the cleaning effect.

[0046] In a specific implementation process, after the guiding plate 34 contacts the insulating cable, the guiding plate 34 drives the bending plate 32 and the swinging rod 31 to move away from the insulating cable, and the torsion spring twists adaptively. Subsequently, the bending plate 32 is clamped on both sides of the insulating cable under the action of the guiding plate 34. The swinging rod 31 rotates under the action of the torsion spring and drives the bending plate 32 to move towards the insulating cable, so that the cleaning bristles 33 on the bending plate 32 are attached to the insulating cable, thereby realizing the cleaning of insulating cables with different diameters; during the rotation of the linkage gear ring 25, the linkage gear ring 25 drives the two swinging rods 31, the bending plate 32 and the cleaning bristles 33 to synchronously move in a circular motion along the axis of the linkage gear ring 25, so that the cleaning bristles 33 clean the dirt and loose materials in the damaged area of the insulating cable, avoiding the influence of dirt and loose materials on subsequent repair.

[0047] It should be noted that the balance block 35 makes the center of gravity of the device located at the bottom, lowering the center of gravity, and the overall device is in a vertical state, thereby cooperating with the moving wheels 17 and the driving wheels 185 to increase the stability of the device and avoid the device tilting or falling due to the influence of wind at high altitude.

[0048] Refer to Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in

[0049] 、

[0050] It should be noted that an insulating tape is sleeved on the outer wall of the insulating tape shaft 42. The insulating tape passes through the limiting groove 46 and extends to the side of the pressing wheel 48 close to the insulating cable. Thus, when the pressing wheel 48 abuts against the outer wall of the insulating cable, the pressing wheel 48 can press the end of the insulating tape against the outer wall of the insulating cable; the torsion spring always applies a torsion force to the hinge rod 47 towards the side close to the insulating cable, so that the pressing wheel 48 always fits against the outer wall of the insulating cable.

[0051] In addition, when the guide rod 43 drives the limiting block 45 and the pressing wheel 48 to move towards the side close to the insulating cable, the hinge rod 47 is blocked by the limiting rod, so that the hinge rod 47 rotates upwards by a specified angle under the action of the torsion spring, thereby keeping the hinge rod 47 in a downward inclined state when not subjected to other external forces, ensuring that the hinge rod 47 does not drive the pressing wheel 48 to swing upwards. Furthermore, when the connecting plate 44 drives the pressing wheel 48 to move towards the side close to the insulating cable, the pressing wheel 48 is located below the limiting block 45, preventing the pressing wheel 48 from swinging upwards and causing the insulating tape to turn upwards and unable to wind around the insulating cable normally; in addition, the controller 52 in this embodiment is a PLC controller in the prior art, which is mainly used to control the start or stop of the bidirectional motor 11 and the driving motor 18, and will not be elaborated here.

[0052] In the specific implementation process, when moving to the damaged part of the insulating cable, the hydraulic rod 50 is started through the controller 52. The telescopic end of the hydraulic rod 50 contracts, and the telescopic end of the hydraulic rod 50 drives the sliding block 51 to move along the sliding groove 49 towards the side close to the linkage gear ring 25. At the same time, the telescopic end of the hydraulic rod 50 pulls the guide rod 43 to rotate towards the side close to the insulating cable. The guide rod 43 drives the connecting plate 44, the limiting block 45 and the pressing wheel 48 to rotate towards the side close to the insulating cable synchronously, so that the pressing wheel 48 fits against the outer wall of the insulating cable and presses the insulating tape against the outer wall of the insulating cable; then the bidirectional motor 11 is started through the controller 52. The output shaft of the bidirectional motor 11 drives the linkage gear ring 25 to rotate. The linkage gear ring 25 drives the guide rod 43, the connecting plate 44, the limiting block 45, the pressing wheel 48 and the insulating tape shaft 42 to move circumferentially along the outer wall of the insulating cable synchronously, winding the insulating tape around the outer wall of the insulating cable. Since the moving wheel 17 drives the device to continue moving, the insulating tape can be wound around the damaged part of the insulating cable. At the same time, the pressing wheel 48 rolls the insulating tape during the circumferential movement, making the bonding effect between the insulating tape and the insulating cable better, thereby realizing the repair of the damaged part of the insulating cable.

[0053] Further, after the repair of a damaged part of the insulated cable is completed, the controller 52 controls the bidirectional motor 11 to close and the hydraulic rod 50 to contract. The telescopic end of the hydraulic rod 50 drives the sliding block 51 to move along the sliding groove 49 away from the linkage gear ring 25, and drives the guiding rod 43 to move away from the insulated cable. At the same time, the torsion spring rebounds and drives the two hinge rods 47 and the connecting rod 21 to synchronously move circumferentially towards the insulated cable. The connecting rod 21 drives the cutter 54 to move synchronously. When the cutter 54 moves towards the insulated cable, it cuts off the insulating tape, which is convenient for subsequent repair of the next damaged part of the insulated cable. When the moving wheel 17 drives the device to move to the next damaged part of the insulated cable, the bidirectional motor 11 is restarted to clean and repair the damaged part, thereby realizing continuous repair of the insulated cable and greatly improving the repair efficiency. Embodiment 2:

[0054] Referring to Figure 10 As shown, on the basis of Embodiment 1, in order to prevent the insulating tape from falling off the outer wall of the insulated cable due to long-term exposure to a high-temperature environment, based on this, in this embodiment, a liquid storage tank 61 is installed at the bottom of the support frame 1. A connecting pipe 62 is connected to the bottom of the liquid storage tank 61, and a connecting pipe 62 is connected to the bottom of the annular spray head 63. The annular spray head 63 is located between the cleaning assembly 3 and the winding assembly 4. The annular spray head 63 is U-shaped, and spray holes are formed inside the annular spray head 63. The annular spray head 63 is located between the arc-shaped plate 12 and the moving wheel 17 on the side close to the insulating tape shaft 42. The annular spray head 63 is electrically connected to the controller 52.

[0055] It should be noted that the bottom of the annular spray head 63 has a notch for the insulated cable to move to the middle of the annular spray head 63, so as to ensure the normal spraying of the annular spray head 63 on the insulated cable.

[0056] In the specific implementation process, after the cleaning bristles 33 clean the outer wall of the insulated cable, the controller 52 controls the annular spray head 63 to open, so as to spray the insulating paint in the liquid storage tank 61 on the damaged part of the insulated cable. Subsequently, the outer wall of the cable sprayed with the insulating paint is wrapped with the insulating tape, so as to bond the insulating tape through the insulating paint, prevent the insulating tape from losing its viscosity and falling off due to long-term exposure to a high-temperature environment, and after the insulating paint solidifies, even if the insulating tape fails due to environmental factors, the insulating paint can still protect the insulated cable in an insulated state, further improving the repair effect of the insulated cable.

[0057] During operation: Step 1: First, open the latch 186 and pull the crossbar 182, causing the crossbar 182 to rotate downward along the hinge of the bent rod 181, and driving the rotating bracket 183, the transfer shaft 184, the driving wheel 185, and the lower transfer gear 187 to move synchronously. Subsequently, move the device above the insulated cable, and clamp the insulated cable under the moving wheel 17. Pull the crossbar 182 upward so that the crossbar 182 rotates upward along the hinge of the bent rod 181 and makes the crossbar 182 in a horizontal state. The two transfer gears 187 mesh with each other, and the driving wheel 185 is clamped with the bottom of the insulated cable. Then close the latch 186 to lock the crossbar 182 and the bent rod 181. During the process of mounting the device on the upper end of the insulated cable, the arc plate 12, the support ring 22, and the linkage gear ring 25 are sleeved outside the insulated cable through the relief groove 28, so that the moving wheel 17 is clamped on the outer wall of the insulated cable. Then start the driving motor 18, and the output shaft of the driving motor 18 drives the rotating shaft 16 and the moving wheel 17 connected thereto to rotate. The rotating shaft 16 drives another rotating shaft 16 and the moving wheel 17 on its outer wall to rotate synchronously through belt drive.

[0058] Step 2: Start the bidirectional motor 11. The two output shafts of the bidirectional motor 11 drive the transmission gear 14 and the transmission shaft 13 to rotate. Subsequently, the transmission gear 14 drives the linkage gear ring 25 to rotate. The linkage gear ring 25 rotates along the T-shaped groove 23 under the cooperation of the T-shaped groove 23 and the T-shaped strip 24. At the same time, during the rotation of the transmission shaft 13, the linkage shaft 26 and the linkage gear 27 rotate synchronously. The linkage gear 27 drives the linkage gear ring 25 to rotate synchronously. During the rotation of the linkage gear ring 25, the linkage gear ring 25 drives the two swing rods 31, the bending plate 32, and the cleaning cilia 33 to move circumferentially along the axis of the linkage gear ring 25 synchronously, so that the cleaning cilia 33 clean the dirt and loose materials in the damaged area of the insulated cable, avoiding the influence of dirt and loose materials on subsequent repair.

[0059] Step 3: After the cleaning cilia 33 clean the outer wall of the insulated cable, the controller 52 controls the annular nozzle 63 to open, so as to spray the insulating paint in the liquid storage tank 61 on the damaged part of the insulated cable. Subsequently, wrap the outer wall of the cable sprayed with the insulating paint with an insulating tape, so as to bond the insulating tape through the insulating paint, avoiding the adhesive failure and shedding of the insulating tape due to long-term exposure to a high-temperature environment. And after the insulating paint solidifies, even if the insulating tape fails due to environmental factors, the insulating paint can still protect the insulated cable in an insulating state, further improving the repair effect on the insulated cable.

[0060] Fourth step: When moving to the damaged part of the insulated cable, the hydraulic rod 50 is activated through the controller 52. The telescopic end of the hydraulic rod 50 contracts, and the telescopic end of the hydraulic rod 50 drives the sliding block 51 to move along the sliding groove 49 towards the side close to the linkage gear ring 25. At the same time, the telescopic end of the hydraulic rod 50 pulls the guiding rod 43 to rotate towards the side close to the insulated cable. The guiding rod 43 drives the connecting plate 44, the limiting block 45, and the pressing wheel 48 to rotate synchronously towards the side close to the insulated cable, so that the pressing wheel 48 fits on the outer wall of the insulated cable, and the insulating tape is pressed on the outer wall of the insulated cable. Subsequently, the bidirectional motor 11 is activated through the controller 52. The output shaft of the bidirectional motor 11 drives the linkage gear ring 25 to rotate. The linkage gear ring 25 drives the guiding rod 43, the connecting plate 44, the limiting block 45, the pressing wheel 48, and the insulating tape shaft 42 to move circumferentially along the outer wall of the insulated cable, and the insulating tape is wound around the outer wall of the insulated cable. Since the moving wheel 17 drives the device to continuously move, the insulating tape can be wound around the damaged part of the insulated cable. At the same time, the pressing wheel 48 rolls the insulating tape during the circumferential movement, making the bonding effect between the insulating tape and the insulated cable better, thereby realizing the repair of the damaged part of the insulated cable.

[0061] Fifth step: When the repair of a damaged part of the insulated cable is completed, the controller 52 controls the bidirectional motor 11 to turn off and the hydraulic rod 50 to contract. The telescopic end of the hydraulic rod 50 drives the sliding block 51 to move along the sliding groove 49 towards the side away from the linkage gear ring 25, and drives the guiding rod 43 to move away from the insulated cable. At the same time, the torsion spring rebounds and drives the two hinge rods 47 and the connecting rod 21 to move circumferentially towards the side close to the insulated cable synchronously. The connecting rod 21 drives the cutter 54 to move synchronously. The cutter 54 cuts the insulating tape when approaching the insulated cable, which is convenient for the subsequent repair of the next damaged part of the insulated cable. When the moving wheel 17 drives the device to move to the next damaged part of the insulated cable, the bidirectional motor 11 is started again to clean and repair the damaged part, thereby realizing the continuous repair of the insulated cable and greatly improving the repair efficiency.

[0062] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
