Description

Technical Field

[0001] This utility model relates to the technical field of spacer devices for heavy-duty unmanned aerial vehicles (UAVs), and more particularly to an automatic spacer disassembly and assembly device based on heavy-duty UAVs. Background Technology

[0002] With the rapid development of the power industry, the scale of 110 kV transmission lines is constantly expanding, and their safe and stable operation plays a crucial role in power supply. Spacer bars, as key components in transmission lines, effectively prevent conductors from colliding and wearing down due to wind vibration, galloping, and other factors, ensuring line safety. However, traditional spacer bar installation and removal mainly rely on manual labor, requiring maintenance personnel to climb towers tens of meters high, making the operation complex and highly dangerous. Therefore, the development of an automated spacer bar installation and removal device based on heavy-duty drones has become an urgent need in the industry. This device aims to utilize the mobility and automation technology of drones to achieve efficient and safe installation and removal of spacer bars, significantly improving the efficiency and quality of transmission line operation and maintenance.

[0003] Existing spacer installation and removal technologies mostly rely on manual operation using simple tools. During work, maintenance personnel must carry wrenches, ropes, and other tools to climb the towers and manually tighten or loosen the spacer's fixing bolts at high altitudes, or use scaffolding or other auxiliary facilities to complete the task. If replacing spacers of different specifications is involved, corresponding tools and equipment must be prepared in advance. This traditional mechanical structure and operation method mainly depends on manual drive and simple mechanical principles, lacking automation and intelligent control, and thus failing to meet the efficiency and precision requirements of modern transmission line operation and maintenance.

[0004] However, traditional manual high-altitude disassembly and assembly of spacers has significant drawbacks. Due to the complex environment at heights, risks such as strong winds, falls, and electric shock constantly threaten the lives of maintenance personnel. Furthermore, manual operation is constrained by physical limitations and environmental factors, resulting in low efficiency. Simultaneously, manual tightening of bolts is difficult to precisely control torque, easily leading to overtightening causing bolt deformation or undertightening causing spacers to detach, severely impacting installation quality and line stability. These problems not only increase maintenance costs but can also trigger line faults and even large-scale power outages. Therefore, more advanced technologies and devices are urgently needed to solve these problems. This paper proposes an automated spacer disassembly and assembly device based on heavy-duty unmanned aerial vehicles (UAVs) to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic disassembly and assembly device for spacers based on heavy-duty drones, which aims to improve the problems of low efficiency, high safety risks, and inaccurate torque control in the prior art of manual high-altitude disassembly and assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic disassembly and assembly spacer device based on a heavy-duty drone includes a heavy-duty drone, a connecting line fixedly connected to the bottom of the heavy-duty drone, a fixing component at the bottom of the connecting line, and an adjustment component inside the connecting line.

[0008] The fixing assembly includes a clamp with its top positioned at the bottom of the heavy-duty UAV. A connecting plate is fixedly connected to the bottom end of the connecting line. Two connecting blocks are fixedly connected to the bottom of the connecting plate. A rotating rod is rotatably connected inside each connecting block. The other side of the rotating rod is rotatably connected inside the clamp. A hydraulic rod is fixedly connected inside the connecting plate. A lifting block is fixedly connected to the output end of the hydraulic rod. A sliding groove is formed inside the lifting block. An L-shaped rod is rotatably connected inside the connecting block. One side of the L-shaped rod is rotatably connected inside the clamp. A limiting post is fixedly connected to the other side of the L-shaped rod. The outer wall of the limiting post is slidably connected inside the sliding groove.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a sliding rod, the outer wall of which is disposed inside the connecting line.

[0011] As a further description of the above technical solution:

[0012] A fixing ring is fixedly connected to one end of the sliding rod, and a connecting groove is provided inside the sliding rod.

[0013] As a further description of the above technical solution:

[0014] The fixing ring has a limiting groove inside, and the outer wall of the connecting wire is disposed inside the limiting groove.

[0015] As a further description of the above technical solution:

[0016] A separation rod is provided on one side of the connecting line, and the outer wall of the sliding rod is slidably connected to the inside of the separation rod.

[0017] As a further description of the above technical solution:

[0018] A fixing block is fixedly connected to the top of the separating rod, and a cam is rotatably connected inside the fixing block.

[0019] As a further description of the above technical solution:

[0020] One end of the cam is fixedly connected to a lever, and the outer wall of the lever is slidably connected inside the fixed block.

[0021] As a further description of the above technical solution:

[0022] The fixed block has a sliding column inside, and a friction convex plate is fixedly connected to the bottom of the sliding column. The outer wall of the friction convex plate is slidably connected inside the connecting groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the clamp achieves its rotation function by activating the hydraulic rod. When the hydraulic rod is activated, it drives the lifting block and the slide groove, and in conjunction with the L-shaped rod and the rotating rod, it enables the clamp to rotate at the bottom of the connecting block, thereby facilitating the gripping and placement of the spacer bar, making it convenient for installation and movement. This solves the problems of low efficiency, high safety risks, and inaccurate torque control in manual high-altitude disassembly and assembly, and improves the efficiency, safety, and reliability of the installation quality.

[0025] 2. In this utility model, the cam achieves its rotation function by rotating the lever. When the lever is rotated, it drives the sliding column and friction convex plate and cooperates with the connecting groove to make the sliding rod slide inside the separating rod, thereby facilitating the adjustment of the two fixing rings and making it convenient to clamp separating rods of different lengths. This solves the problems of the traditional need to carry multiple specifications of separating rods, terrain limitations, and low precision of manual adjustment, and improves the adaptability of the device to different scenarios, work efficiency, and installation accuracy.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an automatic spacer disassembly and assembly device based on a heavy-duty drone, comprising a heavy-duty drone 1. The heavy-duty drone 1 adopts a hexacopter or octacopter frame structure, is made of high-strength carbon fiber material, has excellent wind resistance and lightweight characteristics, can fly stably in winds up to level 6, and has a maximum load of up to 15kg. It can easily carry the entire spacer disassembly and assembly equipment to perform tasks. A connecting line 2 is fixedly connected to the bottom of the heavy-duty drone 1. The connecting line 2 is made of nylon material and has both high flexibility and tensile strength, with a tensile strength of up to 800MPa. It can effectively buffer the vibration during drone flight and ensure the stability of the connection. A fixing component is provided at the bottom of the connecting line 2, and an adjustment component is provided inside the connecting line 2.

[0035] The fixing assembly includes a clamp 3, which is integrally formed from high-strength aluminum alloy with an anodized surface, providing excellent wear resistance and corrosion resistance. The top of the clamp 3 is positioned at the bottom of the heavy-duty drone 1. A connecting plate 5 is fixedly connected to the bottom of the connecting cable 2. The connecting plate 5 is made of steel plate with multiple reinforcing ribs welded to its surface to enhance the overall structural strength. Two connecting blocks 12 are fixedly connected to the bottom of the connecting plate 5. A rotating rod 7 is rotatably connected inside the connecting block 12. The surface of the rotating rod 7 is hardened to a hardness of HRC45, and its other side is rotatably connected to the inside of the clamp 3 via a bearing. To provide stable support for the rotation of clamp 3, the other side of the rotating rod 7 is rotatably connected inside clamp 3. A hydraulic rod 6 is fixedly connected inside the connecting plate 5. A lifting block 9 is fixedly connected to the output end of the hydraulic rod 6. The lifting block 9 adopts a T-shaped structure design, is made of engineering plastic, and has self-lubricating properties, which can reduce frictional resistance during movement. A sliding groove 11 is opened inside the lifting block 9. An L-shaped rod 8 is rotatably connected inside the connecting block 12. One side of the L-shaped rod 8 is rotatably connected inside clamp 3, and a limiting post 10 is fixedly connected to the other side of the L-shaped rod 8. The outer wall of the limiting post 10 is slidably connected inside the sliding groove 11.

[0036] Specifically, in the actual operation of the automatic spacer assembly / disassembly device based on heavy-duty UAVs, the operating mechanism of clamp 3 demonstrates strong practicality and stability. When the spacer needs to be moved, the operator can activate the hydraulic rod 6 via the remote control system. As the core driving component, the hydraulic rod 6 generates a powerful and stable thrust using the hydraulic transmission principle, precisely driving the lifting block 9 to move vertically along the preset track. The movement of the lifting block 9 synchronously drives the displacement of the internal sliding groove 11, allowing the limiting column 10, which is fitted into the sliding groove 11, to slide smoothly under the guidance. The sliding of the limiting column 10 further pulls the L-shaped rod 8, allowing it to rotate flexibly with the connecting block 12 as the fulcrum. At the same time, the rotating rod 7, with its unique limiting design, effectively constrains the rotation amplitude of the L-shaped rod 8, ensuring the accuracy of the movement trajectory. With the combined effect of the two, clamp 3 can achieve multi-angle, high-precision rotation, quickly and firmly clamping and fixing the spacer, ensuring the spacer remains stable during movement. Subsequently, the heavy-duty drone 1, with its powerful power system and precise navigation and positioning, quickly flew to the target location carrying the spacer. The operator then activated the hydraulic rod 6 again, and through reverse operation, released the clamp 3 and precisely fixed the spacer in the designated position on the power transmission line, efficiently completing the installation work.

[0037] Reference Figure 1 , Figure 4 and Figure 5The adjustment assembly includes a sliding rod 21, which is made of hollow high-strength alloy steel with a hard chrome-plated outer wall, providing excellent wear resistance and corrosion resistance. This allows for long-term stable operation in complex high-altitude environments. The outer wall of the sliding rod 21 is located inside the connecting line 2. A fixing ring 15 is fixedly connected to one end of the sliding rod 21. A connecting groove 17 is formed inside the sliding rod 21, and a limiting groove 16 is formed inside the fixing ring 15. The fixing ring 15 is injection molded from engineering plastic, and the limiting groove 16 is stepped, used to tightly engage the connecting line 2, preventing displacement or detachment during adjustment and ensuring structural stability. The outer wall of the connecting line 2 is located inside the limiting groove 16. A separating rod 4 is provided on one side of the connecting line 2. The separating rod 4 is a rectangular tubular structure made of aluminum alloy, combining lightweight and high strength characteristics. Its internal dimensions are the same as those of the sliding rod 21. The outer diameter is precisely matched to form a clearance fit, allowing the sliding rod 21 to slide smoothly inside the separating rod 4 to achieve spacing adjustment. The outer wall of the sliding rod 21 is slidably connected to the inside of the separating rod 4. A fixed block 13 is fixedly connected to the top of the separating rod 4. A cam 19 is rotatably connected inside the fixed block 13. The cam 19 is made of powder metallurgy and has high strength and good wear resistance. A lever 14 fixedly connected to one end is an L-shaped structure made of stainless steel. Its outer wall is slidably connected to the arc groove opened in the fixed block 13. The operator can drive the cam 19 to rotate by turning the lever 14. A lever 14 is fixedly connected to one end of the cam 19. The outer wall of the lever 14 is slidably connected to the inside of the fixed block 13. A sliding column 18 is slidably connected inside the fixed block 13. A friction convex plate 20 is fixedly connected to the bottom of the sliding column 18. The outer wall of the friction convex plate 20 is slidably connected to the inside of the connecting groove 17.

[0038] Specifically, in the operation and maintenance of 110 kV transmission lines, spacer specifications vary. When spacers of different lengths need to be fixed, operators issue commands via a control terminal to manually or remotely drive the lever 14 to rotate. The lever 14, acting as the transmission initiation component, drives the cam 19, fixed inside the fixing block 13, to rotate synchronously. The unique contour structure of the cam 19 changes the compression state of the friction cam 20, thereby releasing the limiting constraint on the friction cam 20. The unrestricted friction cam 20 no longer obstructs the sliding rod 21, allowing the sliding rod 21 to slide freely inside the separating rod 4. At this point, the distance between the two connecting lines 2 can be flexibly adjusted, quickly adapting to spacers of different lengths. After the sliding rod 21 moves to the appropriate position, the operator turns the lever 14 back to the initial position, and the cam 19 re-engages into the connecting groove 17. By squeezing the friction convex plate 20, a strong frictional force is generated to firmly fix the sliding rod 21, ensuring that the entire structure remains stable during the transportation and installation of the heavy UAV 1, avoiding the installation deviation of the spacer due to shaking, and significantly improving the adaptability of the device to diverse operational needs.

[0039] Working principle: When placing and moving the spacer, the hydraulic rod 6 can be activated, which drives the lifting block 9 to rise and fall. Then, the lifting block 9 drives the internal sliding groove 11 to move, which drives the internal limiting column 10 to slide, causing the L-shaped rod 8 to rotate inside the connecting block 12. At the same time, with the restraint of the rotating rod 7, the clamp 3 is driven to rotate, clamping and fixing the spacer to maintain stability. Then, the heavy-duty drone 1 moves it to a suitable position, and the hydraulic rod 6 is activated again to fix the spacer in the appropriate position.

[0040] In addition, when fixing spacers of different lengths, the lever 14 can be rotated, which drives the cam 19 to rotate inside the fixing block 13, releasing the restriction on the friction convex plate 20, thereby releasing the restriction on the sliding rod 21, allowing it to slide inside the separating rod 4, adjusting the distance between the two connecting lines 2 to adapt to different spacers, and when it reaches the appropriate position, the lever 14 is rotated back, and the cam 19 fixes the friction convex plate 20 inside the connecting groove 17, fixing the position of the sliding rod 21 and keeping it stable.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
