Description

Technical Field

[0001] The present invention relates to the technical field of cable surface repair, and more particularly to a cable damage repair device. Background Art

[0002] Cables are key carriers for transmitting energy and signals, and their external insulation and protective layers are crucial to ensuring long-term stable operation. When a cable is damaged, special equipment is usually required to repair it. For example, the patent with announcement number CN120073563B proposes a surface repair device for overhead insulated cables. The device usually includes a support frame, a drive mechanism (such as a bidirectional motor), a cleaning component and a winding component. Its working principle is to use a cleaning component to remove dirt and loose materials from the damaged part of the cable, and then use a winding component to tightly wrap the insulating tape and roll it on the repair part to restore its insulation protection function. The above-mentioned existing technology is a significant improvement over earlier methods (such as simply applying waterproof insulating glue). It solves the problems of low efficiency and unstable quality of manual repair through mechanical automation operation.

[0003] However, the repair device still has a design flaw: its cleaning end (cleaning component) and repair end (winding component) are arranged at both ends of the device's moving wheels; this layout leads to two interrelated problems: first, it unnecessarily extends the cleaning operation path, and the equipment needs to move a longer distance to complete the entire process from cleaning to repair, reducing work efficiency; second, and more critically, when the equipment moves forward after cleaning, its moving wheels will crush the cable section that has just been cleaned. Dust, oil and other pollutants on the cable surface may adhere to the moving wheels, causing secondary contamination to the cleaned and repaired cable surface, affecting the integrity of the cleaning and the bonding quality of the final repair layer, posing a hidden danger to the long-term safe operation of the cable. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cable damage repair device to solve the problem in the above-mentioned background technology of how to avoid secondary contamination caused by the moving wheels of the existing repair device rolling over the cleaned cable segment, so as to optimize the collaborative coordination of cable cleaning and repair processing.

[0006] Furthermore, the power mechanism includes a transmission gear, and there are at least two transmission gears. The side wall of each transmission gear is provided with a pulley. The centers of the transmission gear and the pulley are rigidly connected through a rotating shaft. The rotating shaft is rotatably installed in a shaft seat on the peripheral side of the main shell.

The conduit is equipped with a nozzle regulator located outside the transformer box, and a negative pressure supply valve is installed on the peripheral side of the liquid cavity.

[0008] Furthermore, the distal end of the conduit extending out of the transformer box is configured as an extendable section.

[0009] Furthermore, an axially extending opening for introducing a cable is provided on the peripheral side of the cleaning wheel of the frame, and the cable can fall into the cleaning track of the cleaning wheel through the opening.

[0011] Furthermore, the periphery of the main shell is provided with a guide column that can movably pass through its circumference and extend into its interior. The proximal end of the guide column is rigidly connected to the force-applying head, and the force-applying head can abut the outer side of the cleaning brush head under the push of the guide column; the middle part of the hub bracket is split into two opposing halves, and each half is rotatably clamped in the main shell to allow the guide column to extend into and push the cleaning brush head to move radially.

[0012] Furthermore, the push-pull member includes a crossbeam, a sliding block is slidably engaged in a sliding groove provided on the surface of the crossbeam, and the distal end of the guide column movably passes through the sliding block.

[0013] Furthermore, the cleaning brush head includes a liquid storage cavity, which is filled with an adsorbent cotton layer. A capillary oil guide core is provided on the inner side of the liquid storage cavity. The end of the capillary oil guide core extends into the liquid storage cavity to contact the adsorbent cotton layer. A microporous distribution plate is provided on the outer wall surface of the liquid storage cavity.

[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The cable damage repair device involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 6 as well as Figure 10 - Figure 11 The present invention provides a cable damage repair device, comprising a frame 1, a rotating cleaning module 2 is provided at the center of the frame 1; the rotating cleaning module 2 is symmetrically distributed front to back with the center line of the frame 1 as the axis, the rotating cleaning module 2 comprises a main shell 21, a cleaning wheel 22 is rotatably mounted inside the main shell 21, and a power mechanism 23 for driving the cleaning wheel 22 to rotate is assembled on the circumferential side of the main shell 21; a circumferentially distributed swing arm 3 and a push-pull member 4 are provided on the periphery of each main shell 21, the two ends of each swing arm 3 are respectively hinged to the ear plates on the circumferential side of the main shell 21 and the inner side of the push-pull member 4, and each push-pull member 4 is arranged inside the frame 1 and can move radially; An injection system 5 is provided on the peripheral side of the frame 1, and the injection system 5 includes a transformer box 51, in which a piston push rod 52 is nested. The piston push rod 52 is rigidly connected to the push-pull member 4 through a connecting member, and a nozzle regulator 53 is installed on the section of the piston push rod 52 located outside the transformer box 51; when the circumferentially distributed push-pull members 4 converge centripetally, the angle between the swing arm 3 and the push-pull member 4 decreases to push the rotating cleaning module 2 to separate in the back direction along the cable surface, providing linear cleaning kinetic energy, and at the same time, the push-pull members 4 converge to pull the piston push rod 52 gradually close to the cable, and compress the repair agent in the liquid cavity of the transformer box 51, thereby increasing the pressure kinetic energy.

[0034] In this embodiment, it should be noted that an axially extending opening is provided on the circumference of the cleaning wheel 22 of the frame 1 for introducing the cable. The openings in the side walls of the main housing 21 and the cleaning wheel 22 can be radially sleeved around the outer periphery of the cable, so that the cable, the main housing 21, and the cleaning wheel 22 form a coaxial relationship, ensuring that the cable falls within the cleaning track of the cleaning wheel 22. The power mechanism 23 includes a transmission gear 231, which is provided with at least two transmission gears 231. The side wall of each transmission gear 231 is provided with a pulley 232. The centers of the transmission gear 231 and the pulleys 232 are rigidly connected by a rotating shaft. The rotating shaft is rotatably mounted in a shaft seat on the peripheral side of the main housing 21. The pulleys 232 are connected by a synchronous belt 233, and any rotating shaft is rigidly connected to the motor output shaft through a coupling. The side wall of the main housing 21 is provided with a notch for the end face of the transmission gear 231 to be embedded. The two transmission gears 231 maintain synchronous and unidirectional rotation, thereby ensuring that at least one transmission gear 231 can transmit power to the cleaning wheel 22, driving the entire cleaning wheel 22 to complete a circumferential cleaning action along the surface of the cable. The piston push rod 52 includes a conduit 521. One end of the conduit 521, which is inserted into the inner cavity of the transformer box 51, is fixedly connected to a valve plate 522 in communication therewith. A guide hole 523 is formed on the side of the valve plate 522 near the conduit 521. The reciprocating movement of the valve plate 522 can cause the liquid chamber of the transformer box 51 to adaptively expand or compress. The conduit 521 is equipped with a nozzle regulator 53 located outside the transformer box 51, and a negative pressure supply valve 54 is installed on the periphery of the liquid chamber. When the equipment is reset to the initial working position, the liquid chamber of the transformer box 51 automatically forms a negative pressure reserve state during the mechanical reset process. This negative pressure environment provides negative pressure adsorption power conditions for the autonomous supply system of the repair agent when the negative pressure supply valve 54 is subsequently activated. The distal end of the conduit 521 extending from the transformer box 51 is configured as an extendable section. The operator can dynamically fine-tune the spray angle by manipulating the extendable section of the conduit 521, effectively eliminating the spray blind area. The negative pressure supply valve 54 is connected to a sealed liquid storage tank, in which a repair agent is stored; for example, a polyurethane resin repair agent; The outside of the frame 1 is equipped with a first cylinder 8 for driving the push-pull member 4 to move radially. The push-pull member 4 is rigidly connected to the telescopic shaft of the first cylinder 8 through a connecting member. In this article, all the front-back / left-right position relationships we discuss are based on Figure 1 - Figure 2 These directions are defined by the perspective presented. They have no actual geographical or physical meaning. They are merely a reference framework to help readers understand the content of the article more intuitively. In this way, we can more clearly show the relative position relationship between the various parts, making the entire discussion process easier to understand and follow. Please note that this custom direction identification is only for internal use in this article and does not represent any absolute direction or position in the real world.

[0035] Reference Figure 2 - Figure 3 、 Figure 5 - Figure 9 as well as Figure 12 - Figure 14 In order to adjust the pressing force of the cleaning wheel 22 on the cable and its contact area, the structure of the cleaning wheel 22 is further optimized to provide radial adjustment capability. Specifically, the cleaning wheel 22 includes a hub bracket 221, which is rotatably engaged with the inner wall of the main housing 21; the outer side of the hub bracket 221 is engaged with the transmission gear 231, and the inner side of the hub bracket 221 is equipped with circumferentially arranged cleaning brush heads 222. The cleaning brush heads 222 are elastically connected to the hub bracket 221 via a buffer spring group 223. In order to adjust the displacement of the cleaning wheel 22 in radial direction without interfering with the motion trajectory of the hub bracket 221, the structure of the hub bracket 221 is further optimized, and a lifting adjustment rod 6 is added. Specifically, a guide column 61 is provided on the periphery of the main shell 21, which can movably penetrate the circumference thereof and extend into the interior thereof. The proximal end of the guide column 61 is rigidly connected to a force-applying head 62, which can abut against the outer side of the cleaning brush head 222 under the push of the guide column 61; the hub bracket 221 is partially split into two opposing halves, each half of which is rotatably engaged in the main shell 21, so that the guide column 61 can extend into and push the cleaning brush head 222 to move radially without affecting the circumferential rotation trajectory of the entire cleaning wheel 22; In this embodiment, it should be noted that the push-pull member 4 includes a crossbeam 41, and a slider 42 is slidably engaged in a slide groove provided on the surface of the crossbeam 41. The distal end of the guide post 61 movably passes through the slider 42, which improves the stability of the guide post 61 in the lifting and lowering movement while ensuring that it does not interfere with the movement trajectory of the guide post 61 with the rotating cleaning module 2. Two guide posts 61 symmetrically arranged on the coaxial line are connected by a telescopic connecting rod 7. The telescopic connecting rod 7 is rigidly connected to the telescopic shaft of the second cylinder 9 mounted on the side of the frame 1. This can not only reduce the number of electric drive devices, but also implement synchronous drive of the coaxial jacking adjustment rod 6, while ensuring that the arrangement of the telescopic connecting rod 7 does not hinder the linear displacement of the jacking adjustment rod 6. The first spring 2233 is sleeved on the surface of the movable core shaft 2232, and the first spring 2233 serves as a buffer element. The two ends of the first spring 2233 respectively abut the end surface of the limit plug handle and the inner edge of the port of the fixed sleeve 2231, forming an elastic pre-compression structure in the axial direction to maintain the dynamic matching relationship between the components, so that the movable core shaft 2232 can elastically expand and contract along the inner cavity of the fixed sleeve 2231; the end of the movable core shaft 2232 is fixedly connected to the cleaning brush head 222; In order to further improve the cleaning effect of the cleaning brush head 222 on the cable surface, the structure of the cleaning brush head 222 is further optimized. Specifically, the cleaning brush head 222 includes a liquid storage cavity 2221 fixedly connected to the movable core shaft 2232, the liquid storage cavity 2221 is filled with an adsorption cotton layer 2223, and a capillary oil guide core 2222 is provided on the inner side of the liquid storage cavity 2221. The end of the capillary oil guide core 2222 extends into the liquid storage cavity 2221 to contact the adsorption cotton layer 2223, and a microporous distribution plate 2224 is provided on the outer wall surface of the liquid storage cavity 2221. The capillary oil guide core 2222 can absorb the detergent penetrating into the adsorption cotton layer 2223 and evenly apply it to the cable surface, effectively removing dirt; In order to realize the automatic replenishment of the oil contained in the adsorption cotton layer 2223 during the cleaning process, the structure of the force-applying head 62 is further optimized. Specifically, the force-applying head 62 includes a liquid storage tank 621 connected to the bottom end of the guide column 61, and a trigger valve core 622 is provided in the liquid storage tank 621. The trigger valve core 622 includes a valve plate 6221, and a cone head 6222 is integrally formed at one end of the valve plate 6221. The other end of the valve plate 6221 is elastically connected to the liquid storage tank 621 through a second spring 6223. When the liquid storage tank 621 is attached to the cleaning brush head 222, the cone head 6222 in the trigger valve core 622 will be subjected to the reaction force of the microporous distribution plate 2224 to compress the second spring 6223, that is, to press the cone head 6222 back to the liquid storage tank 621. 223 ; The end of the cone head 6222 is configured as an inclined conical surface. When the outer side of the liquid storage cavity 2221 contacts the conical surface, the cone head 6222 is forced to retract by the squeezing force. Acetone is an alternative cleaning agent. Advantages: One of the strongest and most effective options. Acetone is an extremely strong organic solvent that can quickly dissolve and remove oil, grease, silicone, flux residue, and most organic contaminants from the cable surface. It evaporates very quickly and leaves no residue.

[0036] Working principle of the present invention: The openings on the side walls of the main shell 21 and the cleaning wheel 22 are radially sleeved on the periphery of the cable, so that the cable, the main shell 21 and the cleaning wheel 22 form a coaxial relationship, ensuring that the cable falls accurately into the cleaning trajectory of the cleaning wheel 22; then the first cylinder 8 is started, and its telescopic shaft drives the push-pull member 4 to retract toward the center of the frame 1 through the connecting member, causing the circumferentially distributed push-pull members 4 to synchronously converge centripetally, so that the angle between the swing arm 3 and the push-pull member 4 continues to decrease, and the swing arm 3 is gradually overlapped with the bottom wall of the push-pull member 4; in this process, the swing arm 3 pushes the hinged rotary cleaning module 2 outward, causing the rotary cleaning module 2 to linearly displace along the cable surface, and the two symmetrically arranged groups of rotary cleaning modules 2 are separated to both sides by the thrust, thereby achieving efficient cleaning of the cable surface; at the same time, the push-pull member 4 can synchronously pull the piston push rod 52 toward the cable during the convergence process toward the center of the frame 1, driving the nozzle of the guide tube 521 to gradually approach the side edge of the cable, at this time, the valve plate 522 liquids the transformer box 51 The repair agent in the cavity is compressed. When the conduit 521 reaches the preset spraying position, the cleaning wheel 22 has completed the cleaning operation of the current section to form a process advance. At this time, the nozzle regulator 53 is activated to allow the repair agent in the liquid cavity to be sprayed to the cable surface to be repaired through the guide hole 523, the valve plate 522 and the unobstructed conduit 521. The operator can dynamically adjust the spray angle by manipulating the extendable section of the conduit 521, effectively eliminating the spray blind area. This design not only achieves the pre-cleaning of the cable, but also provides pressure kinetic energy for the delivery of the repair agent, realizing efficient coordination of cable cleaning and repair treatment. After the operation is completed, the equipment is detached from the cable along a motion trajectory opposite to the assembly and reset to the initial position. At this time, the liquid cavity of the transformer box 51 automatically forms a negative pressure reserve state during the mechanical reset process. This negative pressure environment provides negative pressure adsorption power conditions for the autonomous supply system of the repair agent when the subsequent negative pressure supply valve 54 starts the operation, ensuring the closed-loop working cycle of sustainable operation of the equipment. During the above operation, the driving force for the circumferential rotation of the cleaning wheel 22 is provided by the power mechanism 23, specifically: the output shaft of the motor drives the transmission gear 231 rigidly connected thereto to rotate, and the pulley 232 is linked by the synchronous belt 233, so that the two transmission gears 231 keep rotating synchronously in the same direction, thereby ensuring that at least one transmission gear 231 can transmit power to the hub bracket 221 in the cleaning wheel 22, driving the entire cleaning wheel 22 to complete the circumferential cleaning action along the cable surface; During the above operation, in the process of adjusting the pressure of the cleaning wheel 22 on the cable, the telescopic shaft of the second cylinder 9 drives the lifting adjustment rod 6 to move toward the center of the main shell 21, and the force head 62 immediately applies pressure to the outside of the cleaning brush head 222. This force pulls the movable core shaft 2232 and compresses the first spring 2233 to make the cleaning brush head 222 gradually move away from the fixed sleeve 2231, thereby enhancing the fit between the cleaning brush head 222 and the cable surface and expanding the contact area of ​​the capillary oil guide core 2222 to improve the cleaning efficiency; at the same time, when the liquid storage tank 621 fits the cleaning brush head When the valve body is in the liquid storage tank 621, the cleaning agent stored in the liquid storage tank 621 can be received by the microporous distribution plate 2224 and penetrate into the adsorption cotton layer 2223, and finally be adsorbed by the capillary oil guide core 2222 and evenly coated on the cable surface, thereby realizing the dual synergy of precise release of cleaning agent and mechanical decontamination, and significantly enhancing the cable cleaning effect.
