Description

Technical Field

[0001] This invention belongs to the field of climbing guide devices, and more specifically, relates to a climbing guide device suitable for multi-specification insulator strings. Background Technology

[0002] In high-voltage transmission lines, insulator strings are critical components ensuring the safety of power transmission. Because insulators are constantly exposed to the outdoor environment, they face various natural factors such as strong electric fields, strong mechanical stress, temperature variations, wind and rain, and pollution, making them prone to aging and damage, thus affecting the safe and stable operation of the power system. Therefore, regular inspection, maintenance, and cleaning of insulator strings are necessary.

[0003] Patent application CN106869769A discloses a climbing tool for facilitating climbing insulator strings. Paragraph 0018 of the specification describes: after fitting the insulator fastening device onto the insulator and locking the fastening sleeve to a fixed state by adjusting the nut, the upper layer of the ladder is moved downwards along the guide rail and engaged with the lower layer of the ladder. The upper layer of the ladder is then fixed by adjusting the nut. In practical use, insulator strings come in a variety of specifications, including different diameters, lengths, and shapes. This requires climbing equipment to be able to adapt to various specifications of insulator strings in order to improve the equipment's versatility and practicality. However, some current climbing and guiding equipment has certain limitations in terms of specification adaptability. Its applicable scope is often related to specific specifications of insulator strings. When faced with the operational needs of diverse specifications of insulator strings, it is difficult to fully meet the flexible adaptation requirements of on-site working conditions.

[0004] To address these shortcomings, a climbing guide device suitable for insulator strings of various specifications is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a climbing guide device suitable for multi-specification insulator strings, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A climbing guide device suitable for multi-specification insulator strings includes a first placement seat, a second placement seat slidably fitted on one side of the first placement seat, guide seats elastically fitted on both sides of the first and second placement seats, a fixing plate fixed to the bottom of the first and second placement seats, and two claws rotatably fitted on the opposite outer sides of the two fixing plates, with the ends of the two claws engaging near the fixing plates. A contact piece that slides with the guide seat has a slot on it that slides with the fixing plate. A limit plate is fixed on the side of the contact piece away from the claw, and the limit plate is located between the first placement seat and the second placement seat.

[0007] Optionally, both sides of the first and second placement seats are provided with L-shaped grooves, and the guide seat is slidably fitted in the L-shaped groove. Two springs are fixed between the inner wall of the L-shaped groove and one side of the guide seat.

[0008] Optionally, a connecting plate is fixed between the first ends of two adjacent guide seats, and a guide block is fixed at the second end of the guide seat. Two limiting grooves are opened on the side of the contact piece near the first and second placement seats. The end of the guide block away from the guide seat is slidably fitted in the limiting groove. Two electric push rods are fixed at the end of the first placement seat near the second placement seat. The second placement seat is fixed to the output end of the electric push rod. A first through hole is opened on the limiting plate. The output end of the electric push rod passes through the first through hole, and the inner diameter of the first through hole is larger than the outer diameter of the electric push rod.

[0009] Optionally, threaded holes are provided on the inner sides of the limiting plate and the contact piece, and a threaded rod is threaded between two adjacent threaded holes, with the thread directions on both sides of the threaded rod being opposite. A second arc-shaped groove is provided on the outer sides of the two fixing plates, and the end of the claw near the fixing plate rotates and engages in the second arc-shaped groove.

[0010] Optionally, a rotating shaft is fixed to one end of the claw located in the second arc-shaped groove, and a gear is fixed to the first end of the rotating shaft away from the fixed plate. Two adjacent gears mesh, and a first arc-shaped groove is opened on the side of the contact piece away from the limiting plate, and the first arc-shaped groove is connected to the placement groove.

[0011] Optionally, two second through holes are opened on the outer sides of the two fixing plates. The adjacent second through holes are connected to the second arc-shaped groove. The second end of the rotating shaft near the fixing plate is rotated and fitted into the second through hole. Multiple rubber protrusions are fixed on the inner sidewalls of the two adjacent claws.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: As the equipment approaches the insulator string body, the guide seat is squeezed by the insulator string body and slides elastically on both sides of the first and second placement seats, causing the contact pieces to move synchronously. Simultaneously, the claws rotate outside the fixed plate, engaging to grip the insulator string body, providing stable support for the climbing operation. The limiting plate, located between the first and second placement seats, restricts the position of the contact pieces. The sliding fit between the first and second placement seats improves the equipment's adaptability to insulator strings of different diameters. The elastic fit of the guide seats allows the equipment to automatically adjust its position when contacting insulator strings of different shapes or with deviations, ensuring good contact between the contact pieces and the insulator string body and enhancing the stability of the guide. The rotating and engaging structure of the claws tightly grips the insulator string body, providing reliable gripping force and reducing the risk of the claws slipping during climbing, thus improving operator safety. The limiting plate restricts the movement range of the contact pieces, making the entire guiding process more stable and controllable, reducing abnormal situations such as contact piece displacement. If the surface of the insulator string is uneven or its diameter changes, the guide seat will slide within the L-shaped groove. Due to the specific orientation of the L-shaped groove, the guide seat can move vertically or horizontally. Simultaneously, the spring compresses or extends accordingly based on the movement of the guide seat, continuously pushing it to conform to the surface of the insulator string, ensuring stable contact between the contact piece and the insulator string. The L-shaped groove provides a trajectory limit for the sliding of the guide seat, preventing it from swaying or shifting when adapting to changes in the shape of the insulator string. The elastic support of the spring not only allows the guide seat to respond promptly to changes in the insulator string but also absorbs vibrations caused by unevenness in the insulator string surface during climbing, reducing the hard impact of the equipment on the insulator string, thus protecting it from damage and extending its service life.

[0013] During equipment operation, when a guide seat moves under the force of the insulator string body, the connecting plate transmits this action to adjacent guide seats, enabling multiple guide seats to move synchronously. Guide blocks on the guide seats insert into the limiting grooves of the contact pieces. As the guide seats move, the guide blocks slide within the limiting grooves, guiding the contact pieces to move in a specific direction, ensuring that the contact pieces always maintain the same direction of movement as the insulator string body. The connecting plate connects adjacent guide seats into a whole, ensuring a uniform distribution of multi-sided guiding forces. This allows the equipment to operate more harmoniously and stably when adapting to complex structures such as bends and unevenness in the insulator string body. The cooperation between the guide blocks and the limiting grooves reduces the lateral displacement of the contact pieces, minimizing contact piece misalignment during movement. This allows operators to climb along the insulator string body more accurately, reducing safety hazards caused by guiding deviations.

[0014] When the gear drives the rotating shaft to rotate during transmission, the claw also rotates around the shaft. The second through hole connects with the second arc-shaped groove, facilitating the installation and removal of the rotating shaft. The design of the second through hole provides reliable support for the rotating shaft, improving the smoothness of the gear and claw rotation. During equipment operation, stable rotating shaft support reduces vibration and noise, improving the operational stability of the equipment. Furthermore, the connection between the second through hole and the second arc-shaped groove allows operators to quickly disassemble, clean, and lubricate the rotating shaft and gear during equipment maintenance and repair.

[0019] The invention will now be described in further detail with reference to the accompanying drawings.

[0020] Please see Figure 1-7As shown, this embodiment provides a climbing guide device suitable for multi-specification insulator strings, including a first placement seat 2, a second placement seat 3 slidably fitted on one side of the first placement seat 2, guide seats 6 elastically fitted on both sides of the first placement seat 2 and the second placement seat 3, a fixing plate 16 fixed at the bottom of the first placement seat 2 and the second placement seat 3, and two claws 19 rotatably fitted on the opposite outer sides of the two fixing plates 16, with the two claws 19 engaging near the end of the fixing plate 16; The contact piece 12 is slidably engaged with the guide seat 6. The contact piece 12 has a placement groove 13 that is slidably engaged with the fixing plate 16. A limiting plate 10 is fixed on the side of the contact piece 12 away from the claw 19. The limiting plate 10 is located between the first placement seat 2 and the second placement seat 3.

[0021] The first placement seat 2 and the second placement seat 3 are placed on both sides of the insulator string body 1. The distance between the second placement seat 3 and the first placement seat 2 is adjusted by sliding the second placement seat 3 according to the specifications of the insulator string body 1. Next, the placement slot 13 of the contact piece 12 is aligned with the fixing plate 16 and inserted, allowing the contact piece 12 to slide along the fixing plate 16. When the equipment approaches the insulator string body 1, the guide seat 6 is pressed by the insulator string body 1 and slides elastically on both sides of the first placement seat 2 and the second placement seat 3, causing the contact piece 12 to move synchronously. Simultaneously, the claw 19 rotates outside the fixing plate 16, engaging and gripping the insulator string body 1, providing stable support for climbing operations. The limiting plate 10, located between the first placement seat 2 and the second placement seat 3, restricts the position of the contact piece 12. The sliding fit between the first placement seat 2 and the second placement seat 3 improves the adaptability of the equipment to insulator strings of different diameters. The elastic fit of the guide seat 6 enables the equipment to automatically adjust its position when contacting insulator string bodies 1 of different shapes or with deviations, ensuring that the contact piece 12 maintains good contact with the insulator string body 1 at all times, thus enhancing the stability of the guide. The rotating and meshing structure of the claw 19 can tightly hold the insulator string body 1, providing reliable gripping force and reducing the risk of the claw 19 slipping during climbing, thereby improving the safety of the operator. The setting of the limiting plate 10 restricts the movement range of the contact piece 12, making the entire guiding process more stable and controllable, and reducing abnormal situations such as contact piece 12 deviation.

[0022] In this embodiment, both sides of the first placement seat 2 and the second placement seat 3 are provided with L-shaped grooves 5. The guide seat 6 is slidably fitted in the L-shaped groove 5, and two springs 8 are fixed between the inner wall of the L-shaped groove 5 and one side of the guide seat 6. If the surface of the insulator string body 1 is uneven or the diameter changes, the guide seat 6 will slide in the L-shaped groove 5. Since the L-shaped groove 5 has a specific orientation, the guide seat 6 can move in a vertical or horizontal direction. At the same time, the springs 8 will compress or extend accordingly according to the movement of the guide seat 6, continuously pushing the guide seat 6 to fit against the surface of the insulator string body 1, so that the contact piece 12 and the insulator string body 1 have stable contact. The L-shaped groove 5 provides a trajectory limit for the sliding of the guide seat 6, so that the guide seat 6 will not sway or deviate when adapting to changes in the shape of the insulator string body 1. The elastic support of spring 8 not only allows guide seat 6 to respond promptly to changes in insulator string body 1, but also absorbs vibrations caused by uneven surfaces of insulator string body 1 during climbing, reducing the hard impact of equipment on insulator string body 1. This protects insulator string body 1 from damage and extends its service life.

[0023] In this embodiment, a connecting plate 7 is fixed between the first ends of two adjacent guide seats 6, and a guide block 9 is fixed to the second end of the guide seat 6. Two limiting grooves 14 are formed on the side of the contact piece 12 closest to the first placement seat 2 and the second placement seat 3. Both the limiting grooves 14 and the guide block 9 have T-shaped cross-sections. The end of the guide block 9 furthest from the guide seat 6 slides within the limiting groove 14. During equipment operation, when one guide seat 6 moves under the force of the insulator string body 1, the connecting plate 7 transmits this action to the adjacent guide seats 6, enabling multiple guide seats 6 to move synchronously. The guide block 9 on the guide seat 6 inserts into the limiting groove 14 of the contact piece. As the guide seat 6 moves, the guide block 9 slides within the limiting groove 14, thereby guiding the contact piece 12 to move along a specific direction, ensuring that the contact piece 12 always maintains the same direction of movement as the insulator string body 1. The connecting plate 7 connects adjacent guide seats 6 into a whole, ensuring a uniform distribution of multi-sided guiding forces, allowing the equipment to work more harmoniously and stably when adapting to complex structures such as bending and unevenness of the insulator string body 1. The cooperation between the guide block 9 and the limiting groove 14 reduces the lateral displacement of the contact piece 12 and reduces the deviation of the contact piece 12 during movement, enabling operators to climb along the insulator string body 1 more accurately and reducing safety hazards caused by guide deviation.

[0024] In this embodiment, two electric push rods 4 are fixed to one end of the first placement seat 2 near the second placement seat 3. The second placement seat 3 is fixed to the output end of the electric push rod 4. A first through hole 11 is provided on the limiting plate 10, and the output end of the electric push rod 4 passes through the first through hole 11, with the inner diameter of the first through hole 11 being larger than the outer diameter of the electric push rod 4. When it is necessary to adjust the distance between the first placement seat 2 and the second placement seat 3 to accommodate insulator string bodies 1 of different specifications, the operator activates the electric push rod 4. The output end of the electric push rod 4 begins to move, pushing the second placement seat 3 to slide relative to the first placement seat 2. During this process, the output end of the electric push rod 4 passes through the first through hole 11 on the limiting plate 10, which provides sufficient space for movement, allowing the electric push rod 4 to move unimpeded and smoothly complete the distance adjustment operation. The application of the electric push rod 4 enables the adjustment of the distance between the second placement seats 3, allowing control of the distance between the first placement seat 2 and the second placement seat 3 in a short time. The design of the first through hole 11 does not affect the normal operation of the electric push rod 4, but also plays a certain role in limiting and protecting it, reducing the excessive displacement or damage of the electric push rod 4 during operation, while allowing the limiting plate 10 to continue to perform the limiting function of the contact piece 12.

[0025] In this embodiment, threaded holes are provided on the inner sides of both the limiting plate 10 and the contact piece 12. A threaded rod is threadedly engaged between two adjacent threaded holes, and the threads on both sides of the threaded rod are in opposite directions. The operator rotates the threaded rod using a tool, based on the actual thickness of the insulator string body 1. Because the threads on both sides of the threaded rod are in opposite directions, during rotation, the threaded rod, engaged with the threaded holes on the limiting plate 10 and the contact piece 12, will cause the limiting plate 10 and the contact piece 12 to move closer or further apart, thereby adjusting the gap between the limiting plate 10 and the contact piece 12 to ensure a tight fit against the side of the insulator string body 1. After adjustment, the threaded engagement of the threaded rod can lock the limiting plate 10 and the contact piece 12, reducing the risk of loosening due to vibration or other reasons during climbing. The engagement of the threaded rod and the threaded hole provides a reliable method for adjusting the distance between the limiting plate 10 and the contact piece 12. Operators can fine-tune the equipment according to the specific dimensions of different insulator string bodies 1, ensuring a good fit between the equipment and the insulator string body 1, thus enhancing the stability and grip of the equipment during climbing. Furthermore, the threaded connection facilitates disassembly and maintenance of the equipment, allowing for quick separation of the limiting plate 10 and contact piece 12 when parts need to be replaced or the equipment needs repair.

[0026] In this embodiment, both fixing plates 16 have second arc-shaped grooves 18 on their outer sides. The end of the claw 19 closest to the fixing plate 16 rotates and engages within the second arc-shaped groove 18. When the device needs to grip the insulator string body 1, the claw 19 rotates around the rotation axis 20 within the second arc-shaped groove 18. One end of the claw 19 moves along the trajectory of the second arc-shaped groove 18, gradually approaching the surface of the insulator string body 1 until it makes tight contact with and locks into place. When releasing the insulator string body 1, the claw 19 rotates in the opposite direction, returning to its initial position along the second arc-shaped groove 18. The second arc-shaped groove 18 provides a stable trajectory and sufficient rotation space for the claw 19, allowing it to remain stable and accurately conform to the shape of the insulator string body 1 during movement. This design enables the claw 19 to reliably grip the insulator string body 1, reducing the risk of slippage during climbing. Simultaneously, the structure of the second arc-shaped groove 18 limits the rotation range of the claw 19, reducing excessive rotation or abnormal displacement.

[0027] In this embodiment, a rotating shaft 20 is fixed to one end of the claw 19 located within the second arc-shaped groove 18. A gear 21 is fixed to the first end of the rotating shaft 20 away from the fixing plate 16, and two adjacent gears 21 mesh. When one claw 19 rotates due to contact with the insulator string body 1, the rotating shaft 20 drives the gear 21 on it to rotate synchronously. Since the two adjacent gears 21 mesh with each other, the rotation of the gear 21 drives the other gear 21 meshing with it to rotate in the opposite direction, thereby driving the other claw 19 to rotate synchronously in the opposite direction. Through this gear 21 transmission method, the two claws 19 can always maintain synchronous opening and closing, performing uniform and stable clamping or loosening operations on the insulator string body 1, enabling the two claws 19 to move synchronously. When clamping the insulator string body 1, they can apply gripping force evenly, reducing the tilting or slippage of the claw 19 due to uneven force on one side, and improving the stability of the claw 19 gripping the insulator string body 1. Furthermore, the claw 19 can effectively grip the insulator string body 1 with different materials and surface conditions, adapting to various complex working environments.

[0028] In this embodiment, the contact piece 12 has a first arc-shaped groove 15 on the side away from the limiting plate 10, and the first arc-shaped groove 15 is connected to the placement groove 13. When the equipment is installed on the insulator string body 1, part of the structure of the insulator string body 1 is embedded in the first arc-shaped groove 15 of the contact piece 12. The shape of the first arc-shaped groove 15 matches the outer contour of the insulator string body 1, allowing for a tight fit. At the same time, the contact piece 12 is installed by cooperating with the fixing plate 16 through the placement groove 13, so that the contact piece 12 is stably connected to the equipment. During the equipment climbing process, the first arc-shaped groove 15 always maintains good contact with the insulator string body 1, guiding the equipment to move along the direction of the insulator string body 1. The connection design between the first arc-shaped groove 15 and the placement groove 13 provides a dedicated accommodating space for the insulator string body 1, increasing the contact area between the contact piece 12 and the insulator string body 1, making the contact tighter and more stable. This tight contact helps improve the guiding performance of the equipment, enabling the equipment to move more accurately along the trajectory of the insulator string body 1, reducing swaying and deviation. At the same time, the increased contact area can also disperse the pressure on the insulator string body 1 during the climbing process, reducing the risk of damage to the surface of the insulator string body 1.

[0029] In this embodiment, each of the two fixing plates 16 has two second through holes on its outer sides. A servo motor is fixed in one of the second through holes. The adjacent second through hole is connected to the second arc-shaped groove 18. The second end of the rotating shaft 20, near the fixing plate 16, is rotatably fitted into the second through hole. One of the rotating shafts 20 is fixed to the output end of the servo motor. The second end of the rotating shaft 20 is inserted into the second through hole on the fixing plate 16, providing a stable support point for the rotating shaft 20, allowing it to rotate within the second through hole. A gear 21 is fixed to the first end of the rotating shaft 20. When the gear 21 drives the rotating shaft 20 to rotate during transmission, the claw 19 also rotates around the rotating shaft 20. The second through hole is connected to the second arc-shaped groove 18, facilitating the installation and removal of the rotating shaft 20. The design of the second through hole provides reliable support for the rotating shaft 20, improving the smoothness of the rotation of the gear 21 and the claw 19. During equipment operation, the stable support of the rotating shaft 20 can reduce vibration and noise, improving the operational stability of the equipment. In addition, the connection between the second through hole and the second arc-shaped groove 18 facilitates the quick disassembly, cleaning and lubrication of the rotating shaft 20 and gear 21 by the staff during equipment maintenance and repair.

[0030] In this embodiment, multiple rubber protrusions are fixed to the inner sidewalls of two adjacent claws 19. The design of the rubber protrusions increases the friction between the claws 19 and the insulator string body 1, and enhances the gripping force of the claws 19. This enables the device to climb stably on the insulator string body 1 with different materials (such as ceramics, glass fiber, etc.) and surface conditions (smooth, rough, wet, etc.).

[0031] Working principle: The first placement seat 2 is connected to the second placement seat 3: two electric push rods 4 are fixed at one end of the first placement seat 2 near the second placement seat 3, with the output end of the electric push rod 4 facing the second placement seat 3, and the second placement seat 3 is fixed at the output end of the electric push rod 4 so that the second placement seat 3 can slide along the axial direction of the electric push rod 4. Installation of fixing plate 16: Fix a fixing plate 16 at the bottom of the first placement seat 2 and the second placement seat 3. The fixing plate 16 is perpendicular to the bottom surface of the first placement seat 2 and the second placement seat 3, and the fixing plate 16 has reserved installation space for claw 19 on the outer side. Installation of guide seat 6 and spring 8: Guide seat 6 is slidably installed in the L-shaped grooves 5 on both sides of the first placement seat 2 and the second placement seat 3 respectively. Two springs 8 are fixed between the inner side wall of the L-shaped groove 5 and the guide seat 6. The two ends of the springs 8 are connected to the L-shaped groove 5 and the guide seat 6 respectively, so that the guide seat 6 can slide elastically in the L-shaped groove 5. Assembly of connecting plate 7 and guide block 9: Fix connecting plate 7 to the first end of two adjacent guide seats 6, so that the guide seats 6 are linked through connecting plate 7. Fix guide block 9 to the second end of guide seat 6, so that guide block 9 is perpendicular to the surface of guide seat 6. Installation of contact piece 12 and limiting plate 10: Two limiting grooves 14 are opened on the side of contact piece 12 near the placement seat. The end of guide block 9 away from guide seat is inserted into the limiting groove 14 so that contact piece 12 and guide seat 6 slide in cooperation. The limiting plate 10 is fixed on the side of contact piece 12 away from claw 19. The limiting plate 10 is located between the first placement seat 2 and the second placement seat 3. A first through hole 11 is opened on the limiting plate 10 so that the output end of electric push rod 4 passes through the first through hole. The inner diameter of the first through hole is larger than the outer diameter of electric push rod 4 to reserve room for movement. A first arc groove 15 is opened on the side of contact piece 12 away from the limiting plate 10 and the first arc groove 15 is connected to the placement groove 13. The placement groove 13 is used to slide in cooperation with the fixing plate 16. Installation of claws 19 and rotating shaft 20: Claws 19 are respectively installed in the second arc-shaped grooves 18 on the opposite outer sides of the two fixing plates 16. The rotating shaft 20 is fixed at the end of the claw 19 near the fixing plate 16. The second end of the rotating shaft 20 is inserted into the second through hole of the fixing plate 16, so that the rotating shaft 20 can rotate in the second through hole. The gear 21 is fixed at the first end of the rotating shaft 20 away from the fixing plate 16, so that the gears 21 of the two adjacent claws 19 mesh with each other and achieve synchronous rotation. Multiple rubber protrusions are attached to the opposite inner sidewalls of the claws 19 to enhance the gripping friction.

[0032] Threaded holes are made on the inner sides of the limiting plate 10 and the contact piece 12. The two ends of the threaded rod are screwed into the threaded holes on both sides respectively. The distance between the limiting plate 10 and the contact piece 12 is adjusted by rotating the threaded rod.

[0033] During the climbing process, if the diameter of the insulator string body 1 changes or the surface is uneven, the guide seat 6 will automatically slide along the L-shaped groove 5 under the action of the spring 8 to compensate for the change in spacing. At the same time, the guide block 9 will slide in the limiting groove 14 to maintain the guiding trajectory of the contact piece 12. When the equipment climbs to the position of the umbrella skirt of the insulator string body 1, the claw 19 will be pressed as the equipment moves. The gear 21 will drive the two claws 19 to synchronously adjust the opening and closing angle, stagger the edge of the umbrella skirt and re-clamp, so that the gripping force remains stable.

Anyone should understand that structural changes made under the guidance of this invention, and any technical solutions that are the same as or similar to this invention, fall within the protection scope of this invention.
