Description

Technical Field

[0001] The present invention relates to the technical field of cable installation protection, and in particular to a tower climbing anti-fall device for an unmanned aerial vehicle. Background Art

[0002] In the transmission professional tower climbing operation, workers need to climb the power tower to inspect and repair the line cables. Due to the high risk of high-altitude operations, they generally need to wear tower climbing anti-fall devices to ensure the safety of workers. The drone-mounted anti-fall device is a new type of safety equipment used in power line tower climbing inspection, operation and maintenance, etc. It flies to the top of the tower with a tower climbing safety lock and security rope by drone, and uses real-time video transmission technology to achieve the rapid installation and removal of the safety lock on the top of the tower.

[0003] The size of the safety lock of the existing anti-fall equipment for power transmission is relatively fixed. It is difficult to automatically adjust and fix it to the tower cross bars of different widths when in use. When the width of the cross bar is narrow, a larger lock will easily result in loose fixation and large shaking during use. When the width of the cross bar is wide, the lock is small and cannot be inserted into the cross bar for fixation, affecting its use. At the same time, in order to avoid the safety lock from falling off and improve the efficiency of installation, the existing safety lock structure can generally be fixed more conveniently during installation. However, during the disassembly process, it is often difficult to quickly remove the safety lock only through simple operation of the drone. The operation is relatively cumbersome, which affects the construction efficiency to a certain extent. Summary of the invention

[0034] The stabilizing mechanism 11 includes two groups of clamping blocks 27 installed on the lifting column 16. Two groups of device grooves 28 are opened on the lifting column 16. The two groups of device grooves 28 are symmetrically distributed on both sides of the fixed frame 10. The clamping block 27 is fixedly connected with a first rotating shaft 29 and a second rotating shaft 30 rotatably connected to the device groove 28. The first rotating shaft 29 and the second rotating shaft 30 are symmetrically distributed on both sides of the clamping block 27. The second rotating shaft 30 is fixedly connected with a second clockwork spring 31 fixedly connected to the device groove 28. A rotating member 32 is provided in the lifting column 16 for controlling the rotation state of the first rotating shaft 29 when the lifting column 16 is raised or lowered.

[0035] The rotating member 32 includes a winding disk 33 rotatably connected to the device groove 28, the inner wall of the winding disk 33 is fixedly connected to a first clockwork spring 34 fixedly connected to the outer wall of the first rotating shaft 29, the outer wall of the winding disk 33 is fixedly connected to a connecting rope 35, and a pulling member 36 for controlling the pulling state of one end of the connecting rope 35 is provided in the storage cavity 17. The pulling member 36 includes two groups of pulling rods 37 fixedly installed at the bottom of the storage cavity 17, and two groups of lifting grooves 38 connected to the device groove 28 are opened in the lifting column 16. The two groups of pulling rods 37 are respectively slidably fitted with the inner walls of the two groups of lifting grooves 38, and the connecting ropes 35 on both sides are respectively fixedly connected to the top ends of the two groups of pulling rods 37.

[0036] In this embodiment, the drone body 1 is controlled to drive the mechanical arm 8 so that the hook 9 is inserted into the fixed frame 10. The drone body 1 takes off, which can drive the fixed frame 10 to pull up the lifting column 16. Since the overall weight of the device box 5 and the connecting frame 4 is relatively large, the lifting column 16 can only drive the device box 5 to move up when it moves to the top of the storage chamber 17. During this process, the first tension spring 18 is stretched, the space in the storage chamber 17 is increased, and the hydraulic strength is reduced, thereby reducing the pressure in the drive tube 15, pulling the drive rod 14 to slide in the drive tube 15, and the drive rod 14 drives the guide rod 12 to slide in the guide groove 13, so that the clamping rod 6 is away from the connecting frame 4, and a larger width can be opened between the bottom end of the clamping rod 6 and the connecting frame 4, which is convenient for docking when fixed with cross bars of different widths.

[0037] The mechanical arm 8 adopts a folding design, and during the transportation and lifting process of the device box 5, the device box 5 is kept directly below the UAV body 1 to improve the stability during the lifting process. When flying to the required height, the mechanical arm 8 is controlled to extend, and the cross bar is inserted from the gap between the clamping rod 6 and the connecting frame 4 to the area between the device box 5 and the connecting frame 4 for suspension, and the device box 5 is gradually lowered so that the device box 5 is placed on top of the cross bar. After that, the device box 5 no longer moves down, and the control hook 9 continues to move down, so that the fixed frame 10 pushes the lifting column 16 to move down, and the first tension spring 18 pulls back, so that the hydraulic strength in the storage chamber 17 increases, thereby pushing the driving rod 14 in the driving tube 15 to slide, and the driving rod 14 drives the guide rod 12 and the clamping rod 6 to slide and clamp to one side of the connecting frame 4, thereby reducing the gap between the two sides of the cross bar and improving the stability of the fixation.

[0038] It is worth noting that the hydraulic pressure change in the drive tube 15 will control the hydraulic pressure in the sliding groove 21 through the connecting tube 25. When the pressure in the drive tube 15 decreases, the pressure in the sliding groove 21 decreases, and the second tension spring 26 pulls the sliding rod 20 away from the side wall of the guide rod 12, thereby releasing the clamping limit of the bevel gear block 23 on the bevel gear groove 22. At this time, the guide rod 12 can slide to the side away from the connecting frame 4. Conversely, when the pressure in the drive tube 15 increases, the pressure in the sliding groove 21 increases, pushing the sliding rod 20 close to the side wall of the guide rod 12, so that the bevel gear block 23 is clamped into the bevel gear groove 22. At this time, when the guide rod 12 slides toward the side of the connecting frame 4, the bevel gear groove 22 The inclined surface and the inclined surface of the bevel gear block 23 slide relative to each other, pushing the sliding rod 20 to slide back and forth in the sliding groove 21 until the guide rod 12 drives the clamping rod 6 to clamp to the set position, the guide rod 12 stops sliding, and the bevel gear block 23 is clamped into the bevel gear groove 22 for limiting. At this time, the guide rod 12 is always subjected to the hydraulic thrust in the driving tube 15, maintaining the clamping state of the clamping rod 6 on the side wall of the cross bar. When there is a tendency of shaking, the bevel gear block 23 at this time is subjected to the hydraulic thrust in the sliding groove 21 to limit the right-angle side of the bevel gear groove 22, thereby preventing the guide rod 12 from being away from the connecting frame 4 and causing looseness, thereby realizing the function of the safety lock automatically adapting to the width of the cross bar and clamping and limiting.

[0039] When the hook 9 pulls up the fixed frame 10, the lifting column 16 moves up relative to the device box 5, so that the pulling rod 37 moves down relative to the lifting column 16, and the connecting rope 35 is pulled, so that the winding disc 33 on both sides is rotated and wound, and the first spring 34 is compressed, and the first rotating shaft 29 is driven to make the clamping block 27 rotate and clamp, and the second spring 31 is also compressed, and the clamping blocks 27 on both sides are in contact with the two sides of the hook 9 to avoid the device box 5 from swinging greatly during the lifting, transportation and disassembly process, thereby improving the stability of the operation. When the hook 9 needs to release the fixed frame 10, the lifting column 16 moves down relative to the pulling rod 37, and the connecting rope 35 releases the tension, and the first spring 34 rebounds, reducing the rotational force on the first rotating shaft 29. At the same time, the second spring 31 rebounds, driving the second rotating shaft 30 to make the clamping block 27 rotate and reset in the opposite direction, and the clamping block 27 opens to both sides, away from the hook 9, and the clamping limit state is released.

[0040] The device is easy to operate and has strong adaptability. It can be used for adaptive clamping and fixing of cross bars of various widths, and can realize automatic limiting after fixing to reduce shaking. At the same time, it is convenient for disassembly and assembly. The fixing frame 10 can be automatically released by controlling the hook 9 through the drone body 1 to hang up the fixing frame 10, so that the limiting state can be automatically released, so that the clamping rod 6 is away from the connecting frame 4, which is convenient for taking the cross bar out from between the connecting frame 4 and the clamping rod 6. After putting down the fixing frame 10, it can automatically clamp and limit. In addition, the clamping blocks 27 on both sides can prevent the device box 5 from swinging significantly during the lifting and transportation process, thereby improving the stability of the operation.
