Abstract
Description
Technical Field
[0001] This utility model relates to the field of power system maintenance technology, specifically a novel drone-mounted tower-climbing anti-fall device. Background Technology
[0002] The construction and maintenance of power transmission towers are essential high-altitude operations. Due to the height of the towers, workers face a great risk of falling while climbing and working on them. Therefore, the use of fall arresters is crucial. Fall arresters can quickly brake when workers accidentally fall, effectively protecting their lives.
[0003] Traditional fall arrestor installation methods mainly rely on manual operation. Workers need to climb to the top of the transmission tower and manually install the fall arrestor in the designated beam position. This installation method has many drawbacks. Manually climbing the transmission tower is inherently dangerous. During the climb, workers are in a state of no protection or insufficient protection. Once an accident occurs, it can easily cause serious injuries or fatalities. Secondly, the process of manually installing fall arrestors is cumbersome and requires a lot of time and physical strength. This not only reduces work efficiency but also increases the time that workers are exposed at height. Utility Model Content
[0004] The purpose of this invention is to provide a novel drone-mounted tower fall arrestor to solve the problems mentioned in the background art, such as the time-consuming and labor-intensive nature of manually installing fall arrestors and their poor safety.

[0020] 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.
[0021] Please see Figure 1-5 One embodiment provided by this utility model:
[0022] A novel drone-mounted tower climbing anti-fall device includes a drone, with a mounting mechanism and an anti-fall mechanism mounted on its bottom. The mounting mechanism includes a protective cover 11 suspended from the bottom of the drone. A gripper bracket 1 is fixedly connected to the bottom of the protective cover 11, and a gripper body 16 is rotatably connected to the bottom of the gripper bracket 1. A gripper drive mechanism is provided on the surface of the gripper bracket 1. The anti-fall mechanism includes a top plate 2, which is clamped and fixed to the bottom of the gripper body 16. A pull rod 21 is fixedly connected to the bottom of the top plate 2, and a mounting plate is fixedly connected to the bottom of the pull rod 21. 22. The bottom of the mounting plate 22 is fixedly connected to the hanging shaft 23. A guide rod 24 is fixedly connected to the surface of the mounting plate 22. A self-locking mechanism is provided on the surface of the mounting plate 22. The drone-mounted tower fall arrestor uses the drone to carry the mounting mechanism to clamp and place the fall arrestor, thereby facilitating the transfer of the fall arrestor to the crossbeam of the transmission tower. The self-locking mechanism on the fall arrestor automatically locks on the crossbeam, making it convenient for workers to hang safety ropes on the fall arrestor for operation. The installation of this fall arrestor does not require manual tower climbing, saving time and effort, and improving safety.
[0023] Furthermore, the self-locking mechanism includes a rack 3, which is slidably connected to the surface of the mounting plate 22. A push rod 31 is fixedly connected to the top of the rack 3, and a rotating shaft 32 is rotatably connected to the surface of the rack 3. A gear 33 is fixedly connected to one side of the rotating shaft 32, and a baffle 34 is fixedly connected to the other side of the rotating shaft 32. A torsion spring 35 is fixedly connected to the surface of the gear 33, and the end of the torsion spring 35 away from the gear 33 is fixedly connected to the surface of the mounting plate 22. A compression spring 36 is fixedly connected to the surface of the mounting plate 22, and a guide post 37 is fixedly connected to the bottom of the compression spring 36. The guide post 37 is slidably connected to the surface of the mounting plate 22, and a linkage rod 38 is fixedly connected to the bottom of the guide post 37. A positioning pin 39 is fixedly connected to one end of the linkage rod 38, and the positioning pin 39 is slidably connected to the surface of the mounting plate 22. The self-locking mechanism utilizes the gravity of the mounting plate 22 to press the push rod 31 to slide, thereby achieving self-locking of the fall arrestor on the crossbeam of the transmission tower without manual operation.
[0024] Furthermore, the gripper drive mechanism includes a servo motor 12, which is fixedly connected to the surface of the gripper bracket 1. A first connecting rod 19 is fixedly connected to the output shaft of the servo motor 12. A turntable 13 is rotatably connected to the surface of the first connecting rod 19. A lifting rod 14 is slidably connected to the surface of the gripper bracket 1. The end of the turntable 13 away from the first connecting rod 19 is rotatably connected to the surface of the lifting rod 14. A second connecting rod 15 is rotatably connected to the bottom of the lifting rod 14. The end of the second connecting rod 15 away from the lifting rod 14 is rotatably connected to the gripper body 16. A power battery 17 is fixedly connected to the surface of the gripper bracket 1. A remote control receiver 18 is fixedly connected to the surface of the gripper bracket 1. The gripper drive mechanism receives signals from the power battery 17 and is driven to cause the gripper body 16 to automatically grip the top plate 2, thereby lifting the entire fall arrestor.
[0025] Furthermore, the rack 3 and the gear 33 mesh with each other. During the sliding and lifting process, the rack 3 drives the rotating shaft 32 to rotate on the mounting plate 22 through the gear 33. The rotating shaft 32 drives the baffle 34 to rotate synchronously. The mounting plate 22 has a built-in storage groove for the baffle 34, which can store the baffle 34 inside the mounting plate 22. At the same time, the baffle 34 can only rotate 90 degrees on the mounting plate 22. When the baffle 34 is rotated to a horizontal state, it can cooperate with the mounting plate 22 to achieve a limit on the crossbeam of the transmission tower, preventing the fall arrestor from falling off the crossbeam.
[0026] Furthermore, a limiting hole is provided at the top of the rotating shaft 32, and the limiting hole and the baffle 34 are perpendicular to each other. The elastic force of the compression spring 36 acts on the linkage rod 38 through the guide post 37. The linkage rod 38 drives the positioning pin 39 to slide into the limiting hole of the rotating shaft 32. The positioning pin 39 restricts the rotating shaft 32 from continuing to rotate, thereby rotating the relative position between the baffle 34 and the mounting plate 22, thus completing the locking of the fall arrestor.
[0027] Furthermore, the servo motor 12 drives the first link 19 to rotate via the output shaft. The turntable 13 is located at the eccentric position of the first link 19. During the rotation of the first link 19, the lifting rod 14 is driven to move horizontally up and down on the gripper bracket 1 via the turntable 13. During the rotation of the first link 19, one end of the turntable 13 is moved and rotated. The turntable 13 drives the lifting rod 14 to move up and down reciprocally on the gripper bracket 1 via rotation.
[0028] Furthermore, multiple sets of second connecting rods 15 and gripper bodies 16 are provided. When the gripper bracket 1 is raised or lowered, the lifting rod 14 drives multiple sets of gripper bodies 16 to rotate at the bottom of the gripper bracket 1 through multiple sets of second connecting rods 15. The multiple sets of gripper bodies 16 clamp the top plate 2 by rotating, thereby lifting the entire fall arrestor. When the fall arrestor is locked on the crossbeam, the gripper bodies 16 are released, thus completing the installation of the fall arrestor on the crossbeam.
[0029] Working principle: The mounting mechanism drives the first link 19 to rotate through the output shaft of the servo motor 12. Since the turntable 13 is located at the eccentric position of the first link 19, when the first link 19 rotates, it drives the lifting rod 14 to move horizontally up and down on the gripper bracket 1 through the turntable 13. The lifting rod 14 moves up and down, and through multiple sets of second links 15, it drives multiple sets of gripper bodies 16 to rotate at the bottom of the gripper bracket 1, thereby achieving the gripping of the top plate 2. The UAV drives the fall arrestor to move to the top crossbeam of the power transmission tower through the mounting mechanism, releases the multiple sets of gripper bodies 16, and under the guidance of the guide rod 24, the fall arrestor falls on the crossbeam. The crossbeam directly contacts the compression push rod 31. The gravity of the mounting plate 22 compresses the push rod 31, causing the rack 3 to slide up and down. Because the rack 3 and the gear 33 mesh with each other, the rack 3 drives the gear 33, the rotating shaft 32 and the baffle 34 to rotate synchronously. When the baffle 34 rotates to the horizontal state, it cooperates with the mounting plate 22 to achieve the limit on the crossbeam. Meanwhile, the elastic force of the compression spring 36 acts on the linkage rod 38 through the guide post 37. The linkage rod 38 drives the positioning pin 39 to slide into the limiting hole at the top of the rotating shaft 32, restricting the rotating shaft 32 from continuing to rotate and completing the self-locking of the fall arrestor on the crossbeam. At this time, the staff can hang a safety rope on the hanging shaft 23 of the fall arrestor mechanism to carry out the operation. When it is necessary to disassemble the fall arrestor, the drone observes through the camera and remotely controls the servo motor 12 to make the gripper body 16 clamp the top plate 2 again. Then, the positioning pin 39 is released from the limiting position of the rotating shaft 32, the torsion spring 35 drives the baffle 34 to return to the initial state, the fall arrestor is released, and the gripper drive mechanism lifts the fall arrestor to complete the disassembly.
