Description

Technical Field

[0001] This invention belongs to the field of climbing devices, and more specifically, relates to an adaptive insulator climbing device based on a lightweight insulating material. 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 CN105833476U discloses an overlapping insulator climbing device and method. Paragraph 0024 of the specification discloses a top frame, a bottom frame, and frame connecting rods. The top frame and bottom frame are both split structures. Four frame connecting rods are used. The top and bottom frames are connected by these connecting rods and bolts to form the robot's overall frame. The top frame also has a hook for attaching the insulator rods.

[0004] In actual use, during the adjustment of the frame position, the lower arc-shaped inner groove of the lower gripper needs to be supported by the porcelain insulator. This support method will cause the upper and lower ends of the frame to be unbalanced. Although the lower end of the frame is stably attached to the porcelain insulator by the lower arc-shaped inner groove, the upper end of the frame is always suspended. As a result, when the upper clamping device is driven to move, the upper clamping device is prone to displacement relative to the porcelain insulator, which will ultimately affect the climbing efficiency of the frame.

[0005] To address these shortcomings, an adaptive insulator climbing device based on lightweight insulating materials is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an adaptive insulator climbing device based on insulating lightweight materials, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: An adaptive insulator climbing device based on insulating lightweight material includes two support plates. The support plates are provided with a slidable first clamping component and a sliding plate located on one side of the first clamping component. A second clamping component is slidably fitted inside the sliding plate. Both ends of the support plates are fitted with arc-shaped rods by plugging in, and two arc-shaped plates are installed between two adjacent arc-shaped rods. An airbag is slidably fitted on the inner sidewall of the arc-shaped plate. Two positioning components are provided. Each positioning component has a insert plate, a bolt, and two positioning rods fixed on its opposite outer side. The end of the bolt away from the positioning component is threaded into the contact area of ​​two adjacent arc-shaped rods. The end of the insert plate away from the positioning component is located inside the arc-shaped plate, and the end of the positioning rod away from the positioning component is located inside the arc-shaped rod.

[0008] Optionally, both the first engagement assembly and the second engagement assembly include a U-shaped plate and a first rotating shaft rotatably engaged within the U-shaped plate. A plurality of first teeth are fixed on one side of the U-shaped plate, and a first gear that meshes with the first teeth is fixedly engaged on the first rotating shaft.

[0009] Optionally, both the first clamping assembly and the second clamping assembly further include two fixing blocks, which are respectively fixed to the support plate and the sliding plate. Each of the two fixing blocks has a first through hole on one side, and the ends of the two first rotating shafts near the fixing blocks are respectively rotatably fitted into the two first through holes.

[0010] Optionally, both the support plate and the sliding plate are provided with a first guide groove, and the two U-shaped plates are slidably fitted in the two first guide grooves respectively. The relative inner sides of the two adjacent U-shaped plates are fixed with grippers, and the relative inner sides of the two adjacent U-shaped plates are provided with arc-shaped inner grooves.

[0011] Optionally, a second rotating shaft is rotatably fitted to one end of the sliding plate extending from the support plate, and a second gear is fixed to the end of the second rotating shaft away from the sliding plate. Multiple second teeth that mesh with the second gear are evenly distributed and fixed on one side of the support plate.

[0012] Optionally, a second through hole is provided on each of the opposite outer sides of the positioning element, the bolt is located in the second through hole, and threaded holes and positioning holes are provided at both ends of the arc-shaped rod. The end of the bolt away from the positioning element is threaded into two adjacent threaded holes, and the end of the positioning rod away from the positioning element passes through the positioning hole.

[0013] Optionally, both ends of the arc-shaped rod are provided with placement slots, the arc-shaped plate is located in the placement slots, the inner side wall of the arc-shaped plate is fixed with an electric push rod, and the airbag is fixed on the output end of the electric push rod.

[0014] Optionally, slots are provided on the inner sides of two adjacent curved plates, and the outer sides of two adjacent insert plates are located in the two slots respectively.

[0015] Optionally, two guide rails are fixed on the support plate, and two limiting grooves are provided on the sliding plate to slide with the guide rails.

[0016] Optionally, the arc-shaped rod has a slot, and the outer sides of the support plate are fixed with a block, with the end of the block away from the support plate located in the slot.

[0017] 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: The sliding first and second clamping components can adapt to insulator bodies of different sizes and shapes to achieve initial positioning. The combination of arc rods, arc plates and airbags can clamp and fix the insulator body from multiple directions, improving the fit and stability between the device and the insulator body, so that the device will not easily shake or fall off during climbing. The meshing transmission structure of the first tooth and the first gear can convert the rotation of the first rotating shaft into the linear sliding of the U-shaped plate, which makes it easier to control the sliding distance and force of the U-shaped plate, thereby achieving a more stable and reliable grip on the insulator body, enhancing the gripping force of the grabber on the insulator, improving safety during the climbing process, and this transmission method has a simple structure and is easy to maintain. When installing the first and second clamping components, the ends of the two first rotating shafts closest to the fixed block are respectively inserted into the two first through holes. This allows the first rotating shafts to rotate stably within the fixed block, enabling normal meshing transmission between the first gear and the first teeth, and allowing the U-shaped plate to slide smoothly. The fixed block and the first through holes provide stable support and rotational constraint for the first rotating shafts, improving their stability during rotation and reducing the likelihood of wobbling or offset.

[0022] The invention will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figure 1-7 As shown, this embodiment provides an adaptive insulator climbing device based on insulating lightweight material, including two support plates 1. The support plate 1 is provided with a slidable first clamping component and a sliding plate 2 located on one side of the first clamping component. A second clamping component is slidably fitted inside the sliding plate 2. Both ends of the support plate 1 are fitted with arc-shaped rods 20 by plugging in, and two arc-shaped plates 24 are installed between two adjacent arc-shaped rods 20. An airbag 26 is slidably fitted on the inner side wall of the arc-shaped plate 24. Two positioning components 28 are provided. On the opposite outer sides of each positioning component 28, there is a insert plate 35, a bolt 30, and two positioning rods 31. The end of the bolt 30 away from the positioning component 28 is installed in the contact area of ​​two adjacent arc rods 20 through threaded engagement. The end of the insert plate 35 away from the positioning component 28 is located inside the arc plate 24, and the end of the positioning rod 31 away from the positioning component 28 is located inside the arc rod 20.

[0024] First, place the two support plates 1 on both sides of the insulator body 34. By adjusting the positions of the first and second clamping components on the support plates 1 and the sliding plate 2, the insulator body 34 is initially clamped. Next, insert the arc-shaped rods 20 into both ends of the support plates 1. Using the bolts 30, insert plates 35, and positioning rods 31 on the positioning components 28, the adjacent arc-shaped rods 20 are fixedly connected. At the same time, insert plates 35 are inserted into the arc-shaped plates 24, and positioning rods 31 are inserted into the arc-shaped rods 20, completing the installation and fixing of the arc-shaped rods 20 and the arc-shaped plates 24. Finally, according to the shape of the insulator body 34, by controlling the expansion and contraction of the air bladders 26 on the inner sidewall of the arc-shaped plates 24, the air bladders 26 are made to fit tightly against the surface of the insulator body 34. The sliding first and second clamping components can adapt to insulator bodies 34 of different sizes and shapes to achieve initial positioning. The combination of the arc rod 20, arc plate 24 and airbag 26 can fix the insulator body 34 in a ring from multiple directions, improving the fit and stability between the device and the insulator body 34, so that the device will not easily shake or fall off during climbing.

[0025] In this embodiment, both the first and second clamping components include a U-shaped plate 12 and a first rotating shaft 17 rotatably fitted within the U-shaped plate 12. A plurality of first teeth are fixed on one side of the U-shaped plate 12, and a first gear 18, meshing with the first teeth, is fixedly fitted on the first rotating shaft 17. During the process of the first and second clamping components approaching the insulator body 34, the first teeth on the U-shaped plate 12 mesh with the first gear 18 for transmission. When the U-shaped plate 12 contacts the surface of the insulator body 34 during sliding, rotating the first rotating shaft 17 drives the first gear 18 to rotate. The first gear 18, through meshing with the first teeth, drives the U-shaped plate 12 to slide along the first guide groove 11, allowing the gripper 14 to fit more tightly against the insulator surface. The meshing transmission structure of the first tooth and the first gear 18 can convert the rotation of the first rotating shaft 17 into the linear sliding of the U-shaped plate 12, which makes it easier to control the sliding distance and force of the U-shaped plate 12, thereby achieving a more stable and reliable grip on the insulator body 34, enhancing the gripping force of the gripper 14 on the insulator, improving safety during the climbing process, and this transmission method has a simple structure and is easy to maintain.

[0026] In this embodiment, both the first and second clamping components further include two fixing blocks 15, which are respectively fixed to the support plate 1 and the sliding plate 2. Each fixing block 15 has a first through hole 16 on one side. The ends of two first rotating shafts 17 near the fixing blocks 15 are rotatably engaged within the two first through holes 16. A second servo motor is fixed to one side of each fixing block 15, and one end of each first rotating shaft 17 is fixed to the output end of the second servo motor. When installing the first and second clamping components, the ends of the two first rotating shafts 17 near the fixing blocks 15 are inserted into the two first through holes 16, allowing the first rotating shafts 17 to rotate stably within the fixing blocks 15. This ensures normal meshing and transmission between the first gear 18 and the first teeth, allowing the U-shaped plate to slide smoothly. The fixing blocks 15 and the first through holes 16 provide stable support and rotational constraint for the first rotating shafts 17, improving their stability during rotation and reducing any wobbling or deviation.

[0027] In this embodiment, both the support plate 1 and the sliding plate 2 are provided with first guide grooves 11. Two U-shaped plates 12 are slidably fitted within the two first guide grooves 11. A gripper 14 is fixed to the inner side of each of the two adjacent U-shaped plates 12, and an arc-shaped inner groove 32 is provided on the inner side of each of the two adjacent U-shaped plates 12. A second guide groove 3 is provided on the support plate 1, and the U-shaped plate 12 near the second gear 8 is located within the second guide groove 3. When the first and second engaging components are slid, the U-shaped plates 12 slide along the first guide grooves 11 on the support plate 1 and the sliding plate 2. When the two adjacent U-shaped plates 12 approach the insulator body 34, the grippers 14 on their inner sides contact the surface of the insulator body 34. By further adjusting the position of the U-shaped plates 12, the grippers 14 better fit the insulator body 34, and the arc-shaped inner groove 32 better adapts to the arc-shaped contour of the insulator. The first guide groove 11 provides guidance for the sliding of the U-shaped plate 12, enabling the U-shaped plate 12 to slide along a predetermined direction and reducing the occurrence of deviation or jamming. The gripper 14 increases the contact area and friction with the surface of the insulator body 34. The design of the arc-shaped inner groove 32 can better fit the arc-shaped structure of the insulator body 34, further enhancing the gripping effect on the insulator body 34, and enabling the gripper 14 to better adapt to the shape of the insulator body 34, thereby improving the stability during the climbing process.

[0028] In this embodiment, the sliding plate 2 extends out of the support plate 1 and is rotatably coupled to a second rotating shaft 33. A second gear 8 is fixed to the end of the second rotating shaft 33 away from the sliding plate 2. Multiple second teeth 6, meshing with the second gear 8, are evenly distributed and fixed on one side of the support plate 1. A first servo motor 7 is fixed on the sliding plate 2, and one end of the second rotating shaft 33 is fixed to the output end of the first servo motor 7. When it is necessary to adjust the position of the sliding plate 2 relative to the support plate 1, the second rotating shaft 33 is rotated, causing the second gear 8 to rotate. Since the second gear 8 meshes with the second teeth, the rotation of the second gear 8 is converted into the sliding plate 2 sliding linearly along the support plate 1, thereby achieving the adjustment of the position of the second clamping assembly. Through the meshing transmission of the second gear 8 and the second teeth, the position of the sliding plate 2 can be adjusted, thereby adjusting the relative position between the second clamping assembly and the insulator body 34, improving the adaptability of the second clamping assembly to different working conditions, and enabling the second clamping assembly to better meet the needs of various insulator body 34 climbing operations. Furthermore, this transmission method is simple to operate, provides smooth transmission, and facilitates rapid adjustments during climbing.

[0029] In this embodiment, the positioning element 28 has second through holes 29 on its opposite outer sides. Bolts 30 are located within the second through holes 29. Both ends of the arc-shaped rod 20 have threaded holes 21 and positioning holes 22. The end of the bolt 30 furthest from the positioning element 28 is threaded into two adjacent threaded holes 21, and the end of the positioning rod 31 furthest from the positioning element 28 passes through the positioning hole 22. When installing the arc-shaped rod 20, the bolt 30 is passed through the second through hole 29 on the positioning element 28, and then one end of the bolt 30 is threaded into the threaded holes 21 at the ends of two adjacent arc-shaped rods 20. Simultaneously, the positioning rod 31 is inserted into the positioning hole 22 at the end of the arc-shaped rod 20. Through the tightening of the bolt 30 and the positioning of the positioning rod 31, the connection between the arc-shaped rod 20 and the positioning element 28, as well as the adjacent arc-shaped rods 20, is achieved. The engagement of the bolt 30 and the threaded holes 21 ensures a firm connection between the arc-shaped rods 20. The positioning rod 31 and the positioning holes 22 assist in positioning and reduce the rotation of the arc-shaped rod 20, further enhancing the stability of the connection.

[0030] In this embodiment, both ends of the arc-shaped rod 20 are provided with placement grooves 23. The arc-shaped plate 24 is located in the placement grooves 23, and an electric push rod 25 is fixed to the inner side wall of the arc-shaped plate 24. The airbag 26 is fixed to the output end of the electric push rod 25. When installing the arc-shaped plate 24, the arc-shaped plate 24 is placed in the placement grooves 23 at both ends of the arc-shaped rod 20. Then, the electric push rod 25 is activated. The output end of the electric push rod 25 pushes the airbag 26 towards the surface of the insulator body 34. After the airbag 26 contacts the surface of the insulator body 34, the stroke of the electric push rod 25 is adjusted to make the airbag 26 fit tightly against the surface of the insulator body 34. The placement grooves 23 provide installation positioning and support for the arc-shaped plate 24, improving the accuracy of the installation of the arc-shaped plate 24. The electric push rod 25 can control the degree of contact between the airbag 26 and the surface of the insulator body 34, so that the airbag 26 can better adapt to insulator bodies 34 of different shapes and sizes.

[0031] In this embodiment, slots 27 are provided on the inner sides of the two adjacent arc-shaped plates 24, and the outer sides of the two adjacent insert plates 35 are respectively located in the two slots 27. When installing the positioning member 28 and the arc-shaped plates 24, the insert plates 35 are inserted into the slots 27 on the inner sides of the adjacent arc-shaped plates 24. Through the cooperation between the insert plates 35 and the slots 27, the connection and positioning between the positioning member 28 and the arc-shaped plates 24 are realized, thereby improving the positional stability of the arc-shaped plates 24 during use and reducing the displacement or rotation of the arc-shaped plates 24 during use.

[0032] In this embodiment, two guide rails 4 are fixed on the support plate 1, and two limiting grooves 5 are provided on the sliding plate 2 to slide and engage with the guide rails 4. When installing the sliding plate 2, the limiting grooves 5 on the sliding plate 2 are aligned with the guide rails 4 on the support plate 1, and then the sliding plate 2 is slidably installed on the support plate 1 along the guide rails 4. When the sliding plate 2 slides and adjusts its position relative to the support plate 1, the engagement of the guide rails 4 and the limiting grooves 5 allows the sliding plate 2 to slide smoothly along a straight line. The engagement of the guide rails 4 and the limiting grooves 5 provides guidance and limitation for the sliding of the sliding plate 2, reducing the possibility of offset or wobbling during the sliding process.

[0033] In this embodiment, the arc-shaped rod 20 has a slot 36, and a locking block 19 is fixed on each of the opposite outer sides of the support plate 1. The end of the locking block 19 away from the support plate 1 is located in the slot 36. When installing the arc-shaped rod 20, the locking block 19 on the support plate 1 is aligned with the slot 36 on the arc-shaped rod 20, and then the locking block 19 is inserted into the slot 36. Through the cooperation between the locking block 19 and the slot 36, the support plate 1 and the arc-shaped rod 20 are initially fixed, and then further fixed by bolts 30.

[0034] Working principle: Install guide rail 4 and sliding plate 2: Fix two parallel guide rails 4 on the upper surface of support plate 1, align the limiting groove 5 on sliding plate 2 with guide rail 4, and slide sliding plate 2 along guide rail 4 to form a structure in which sliding plate 2 and support plate 1 can slide relative to each other. Install the first clamping assembly: Slide the U-shaped plate 12 into the first guide groove 11 of the support plate 1, with the first tooth on one side of the U-shaped plate 12 facing the insulator body 34. Fix the fixing block 15 on the support plate 1. The first rotating shaft 17 passes through the first through hole 16 of the fixing block 15. One end is fixedly connected to the first gear 18 in the U-shaped plate 12, and the other end is connected to the second servo motor, so that the first gear 18 meshes with the first tooth of the U-shaped plate 12. When the first rotating shaft 17 is rotated, the U-shaped plate 12 can be driven to slide in the first guide groove 11. Install the second engagement assembly: Install the U-shaped plate 12, the fixing block 15, the first rotating shaft 17 and the first gear 18 in the first guide groove 11 of the sliding plate 2 in the same manner to form the second engagement assembly. The second rotating shaft 33 is installed at one end of the sliding plate 2 that extends out of the support plate 1. The second gear 8 is fixed at the shaft end and meshes with the second tooth 6 on the side of the support plate. The other end of the second rotating shaft 33 is connected to the first servo motor. Connecting the arc-shaped rod 20 to the support plate 1: Fix the locking blocks 19 on the outer sides of both ends of the support plate 1, align the locking slots 36 at both ends of the arc-shaped rod 20 with the locking blocks 19, insert the locking blocks 19 to achieve initial fixation, the threaded holes 21 and positioning holes 22 at both ends of the arc-shaped rod 20 correspond to the connection positions of the support plate 1 respectively, in preparation for subsequent bolt 30 fixation; Install the arc plate 24 and the air bag 26: Place the arc plate 24 into the placement slots 23 at both ends of the arc rod 20, so that the inner side of the arc plate 24 faces the insulator body 34. Fix the electric push rod 25 on the inner wall of the arc plate 24. The output end of the electric push rod 25 is connected to the air bag 26. Adjust the position of the output end of the electric push rod 25 so that the air bag 26 can slide along the inner side of the arc plate 24. Slots 27 are opened on the opposite inner sides of adjacent arc plates 24 for connecting the insertion plate 35 of the positioning member 28. Fixing adjacent arc-shaped rods 20: Insert the insert plate 35 on the outside of the positioning member 28 into the slot 27 of the adjacent arc-shaped plate 24, so that the insert plate 35 and the slot 27 cooperate to fix the position of the arc-shaped plate 24, check the stability of all connection parts, and make the arc-shaped rod 20, the arc-shaped plate 24 and the positioning member 28 form a closed ring structure. Testing the sliding of the first and second clamping components: Start the second servo motor to drive the first rotating shaft 17 to rotate, check whether the U-shaped plate 12 slides smoothly in the first guide groove 11, and whether the gripper 14 and the arc-shaped inner groove 32 can fit against the surface of the insulator body 34. Start the first servo motor, and through the meshing of the second gear 8 and the second tooth 6, test the sliding adjustment function of the sliding plate 2 relative to the support plate 1. Adjusting the fit of the airbag 26: Start the electric push rod 25 to push the airbag 26 towards the insulator body and observe whether the airbag can adapt to the shape of the insulator. Adjust the stroke of the electric push rod 25 to the optimal fit state. Check whether the connection of all lightweight insulating material components is firm, so that the overall weight of the device is light and the insulation performance is good.

[0035] The U-shaped plate 12 of the first and second clamping components slides through the meshing transmission of the first gear 18 and the first tooth: when the second servo motor drives the first rotating shaft 17 to rotate, the first gear drives the U-shaped plate to move along the first guide groove 11 of the support plate 1 or the sliding plate 2, so that the arc-shaped inner groove 32 of the gripper 14 clamps or loosens the insulator body 34. The displacement of the sliding plate 2 is achieved through the meshing of the second gear 8 and the second tooth 6. The first servo motor drives the second rotating shaft 33 to rotate, the second gear rolls along the second tooth, and drives the sliding plate to slide linearly along the guide rail 4, adjusting the distance between the second clamping component and the first clamping component, providing a displacement basis for the climbing action.

[0036] The first and second clamping components are fixed and moved alternately. When the first clamping component clamps the insulator body 34, the second clamping component moves upward. After the first clamping component is fixed, the second clamping component unlocks and follows. Climbing is achieved through a cycle of fixing-moving-fixing.
