[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0026] A high-altitude hanging and retraction grounding wire device, combined with Figure 1 As shown, it includes a grounding hook 1 and an upper pull rope 10. The grounding hook 1 is provided with a grounding wire 13 and a herringbone end 2. One end of the upper pull rope 10 is herringbone and is hung on the herringbone end 2. The other end of the upper pull rope 10 passes around the lower crossbeam of the grounding pull ring and hangs down to the ground. The upper pull rope 10 is used to pull the grounding hook 1 up and down.
[0027] The grounding hook 1 is an inverted L-shape. The grounding wire 13 is set at the bottom of the vertical body of the grounding hook 1, and the herringbone end 2 is set at the outer end of the top horizontal body of the grounding hook 1 and is set along its length. Thus, the attitude of the grounding hook 1 in the high air can be easily controlled by the pull rope 10.
[0028] like Figures 4 to 5As shown, a groove is provided on the lower surface of the horizontal body of the grounding hook 1. The end of the herringbone-shaped end 2 is hemispherical to prevent jamming when it is hung on the lower crossbeam of the grounding pull ring; a rotating shaft 4 is provided in the middle of the herringbone-shaped end 2, and a rotating tongue 3 is pivotally connected to the rotating shaft 4. The free end of the rotating tongue 3 is an arc-shaped groove. When the arc-shaped groove is rotated to the lower part of the horizontal body of the grounding hook 1, it is used to lock the lower crossbeam of the grounding pull ring from the upper surface. At the same time, when the opening of the arc-shaped groove is facing down, the arc-shaped groove is accommodated in the groove on the grounding hook 1; the pivot end of the rotating tongue 3 is connected to a lower wire removal hook pull rope 11 that hangs down to the ground. A fixing ring 5 is provided on the grounding hook 1. The lower wire removal hook pull rope 11 passes through the fixing ring 5 and hangs down to the ground. Pulling the lower wire removal hook pull rope 11 can drive the rotating tongue 3 to rotate around the rotating shaft 4, thereby lifting the head of the grounding hook 1. Then, with the cooperation of the lower wire removal hook pull rope 11 and the upper wire pull rope 10, the grounding wire 13 can be retrieved.
[0029] A clamping mechanism is provided on the longitudinal part of the grounding hook 1. This clamping mechanism engages with the rotating tongue 3 from the lower surface of the grounding pull ring's lower crossbeam to clamp and release the grounding pull ring's lower crossbeam, thereby effectively preventing power production safety accidents caused by loose grounding wire connections. Figures 2 to 3 As shown, the clamping mechanism includes a spring 6, an upper slider 7, a lower slider 8, and a worm gear 9 arranged sequentially from top to bottom and tightly assembled. The upper slider 7 and the lower slider 8 are both wedge-shaped, and their inclined surfaces are arranged opposite each other.
[0030] The upper slider 7 is fitted onto the vertical body of the grounding hook 1 through a through hole at one end near the lower slider 8. The lower slider 8 is horizontally slidable on the side of the vertical body of the grounding hook 1, with the inclined surface of the lower slider 8 fitting against the inclined surface of the upper slider 7. The spring 6 is fitted onto the vertical body of the grounding hook 1, with its top end connected to the grounding hook 1 and its bottom end connected to the upper slider 7, thus ensuring that the inclined surface of the lower slider 8 fits tightly against the inclined surface of the upper slider 7. A threaded opening is provided at the bottom of the lower slider 8. The worm gear 9 is horizontally positioned and meshes with the bottom thread of the lower slider 8. A shaft pin 14 passes through the inside of the worm gear 9. The shaft pin 14 is rotatably positioned on the side of the vertical body of the grounding hook 1 via a bearing seat located on the side of the vertical body of the grounding hook 1. A synchronous wheel 15 is provided at one end of the shaft pin 14. An auxiliary pull wire 12 is provided on the synchronous wheel 15. Both ends of the auxiliary pull wire 12 hang down to the ground. The auxiliary pull wire 12 is used to drive the synchronous wheel 15 to rotate, thereby driving the shaft pin 14 and the worm gear 9 to rotate, thereby driving the lower slider 8 to move horizontally and controlling the upper slider 7 to move up and down. This allows the upper slider 7 to cooperate with the rotating tongue 3 to clamp and release the lower crossbeam of the grounding pull ring.
[0031] To ensure that the lower slider 8 does not detach from the grounding hook 1 during horizontal movement, a first locking block is provided on the rear wall where the lower slider 8 and the grounding hook 1 are slidably connected. The first locking block is horizontally positioned. A first locking groove is provided on the vertical side of the grounding hook 1 at a position opposite to the first locking block. The first locking groove cooperates with the first locking block to ensure that the lower slider 8 does not detach from the grounding hook 1 during horizontal movement.
[0032] To ensure that the upper slider 7 does not twist during its up-and-down movement along the grounding hook 1, a second locking block is provided on the inner wall of the through hole through which the upper slider 7 passes through the grounding hook 1. The second locking block is arranged longitudinally. A second locking groove is provided on the side wall of the grounding hook 1 at the position opposite to the second locking block. The second locking groove cooperates with the second locking block to ensure that the upper slider 7 does not twist during its up-and-down movement along the grounding hook 1.
[0033] In use, the present invention first uses a drone to pass the upper pull rope 10 through the grounding pull ring, and pulls the upper pull rope 10 downward, causing the grounding hook 1 to rise with the grounding wire 13. When the grounding hook 1 approaches the lower crossbeam of the grounding pull ring, the posture of the V-shaped end 2 of the grounding hook 1 is adjusted to be in a hookable state. The upper pull rope 10 is pulled forcefully, and the grounding hook 1 springs onto the lower crossbeam of the grounding pull ring. The rotating tongue 3 is on the upper surface of the lower crossbeam of the grounding pull ring. At this time, the lower crossbeam of the grounding pull ring is engaged in the arc-shaped groove of the rotating tongue 3. Pulling the auxiliary pull line 12 drives the lower slider 8 to move to the right, squeezing the upper slider 7 upward to clamp the lower crossbeam of the grounding pull ring, thus achieving self-locking.
[0034] After maintenance, first control the auxiliary pull line 12 to return the upper slider 7 and lower slider 8 to their original positions, then pull down the lower line hook removal rope 11 to drive the rotating tongue 3 to rotate around the rotating shaft 4, thereby lifting the head of the grounding hook 1; finally, the lower line hook removal rope 11 cooperates with the upper line pull rope 10 to realize the recovery of the grounding wire 13.
[0035] This invention allows workers to work at heights without having to climb to a height during the process of attaching and retrieving grounding wires, thus reducing the amount of work that workers need to do at heights, thereby reducing work risks and improving work efficiency.
