The laser radar 3 and the optoelectronic pod 4 are installed on the main box 11 of the robot body 1. The front end of the main box 11 is equipped with an auxiliary box 12 for accommodating the electrical testing and grounding mechanism 7. The four-degree-of-freedom robotic arm 8 is fixedly connected to the main box 11. When working, it grabs the electrical testing and grounding mechanism 7 and hangs it on the electrical testing ring of the wire for electrical testing.
[0045] The main box 11 is equipped with a winch 6, which includes a first reel 61 and a first rope 62. The first reel 61 is connected to a winch motor 64 and is installed on a winch frame 63.

The winch 6 is connected to the gripper mechanism 5, and part of the gripper mechanism 5 extends out of the outside of the main box 11, which is used to grasp the cross arm of the electric pole to ensure the stability of the robot body 1 and prevent shaking. During the process of the robot body 1 rising, working and descending, the photoelectric pod 4 is connected to the remote control by a network cable, and the observed image is transmitted to the remote control end through network communication for display. The laser radar 3 returns the distance measurement information to the main control board, and the main control board then feeds back to the remote control through serial communication. The photoelectric pod 4 and the laser radar 3 cooperate to measure the distance of the grounding ring, the overhead cable and the position of the robot body 1 moving up and down.

When the two first motors 53 drive their respective first gears 52 to rotate, the corresponding first racks 54 meshed therewith are controlled to move closer or farther away from each other. Clips 55 are respectively fixed on the two first racks 54. When the two first racks 54 move closer, the two clips 55 can grip the cross arm of the pole; when the two first racks 54 move away from each other, the two clips 55 loosen the cross arm of the pole.
[0048] Embodiment three:
[0049] See also Figure 5 , Figure 6 As shown, this embodiment provides a transverse moving platform 9, which is assembled in the main box 11 of the electrical testing and grounding robot described in Example 1, and is connected to two winches 6.

When the second motor 96 and / or the third motor 97 drive the first screw rod 92 and / or the second screw rod 93 to rotate, the hoist 6 connected to the first slider 94 and / or the second slider 95 and the gripper mechanism 5 connected thereto are driven to translate, and before the gripper mechanism 5 grips the cross arm of the electric pole, the gripper mechanism 5 can adjust the gripping cross arm position to avoid obstacles such as insulators or bolts on the cross arm, thereby improving the stability of the gripper mechanism 5 gripping the cross arm of the electric pole.
[0050] Embodiment 4:
[0051] See also Figure 8 As shown, this embodiment provides a guide rail moving mechanism 31, such as Figure 1As shown, it is assembled on the main box 11 of the electrical grounding robot in the first embodiment. The guide rail moving mechanism 31 includes a guide rail frame 32, a third screw rod 33, a fourth motor 34 and a placer 35. The fourth motor 34 is placed between the bottom plate and the partition of the guide rail frame 32. One end of the third screw rod 33 is connected to the fourth motor 34 through a plum blossom coupling above the partition, and the other end of the third screw rod 33 passes through the placer 35 and is fixedly connected to the top plate of the guide rail frame 32. The laser radar 3 is installed on the placer 35. When the fourth motor 34 drives the third screw rod 33 to rotate, the placer 35 on the third screw rod 33 moves up or down. At this time, the laser radar 3 installed on the placer 35 also moves up or down. The guide rail moving mechanism 31 can adjust the height of the laser radar 3.

The small bevel gear 26 is connected to the sixth motor 28 on the DC motor frame 27 to drive the small bevel gear 26 and the large bevel gear 25 to rotate, thereby driving the second reel 22 to rotate. The sixth motor 28 is a DC motor, and the DC motor frame 27 is fixed on the frame-type base 21.
[0055] The four second reels 22 are arranged in pairs at the front and rear ends of the frame base 21. Each second reel 22 is connected to one end of a corresponding second rope 23, and the other ends of the four second ropes 23 are fixedly connected to the four connections. When the electrical testing and grounding robot is hung on the cross arm of the electric pole through the drone, each sixth motor 28 on the ground traction device 2 controls the corresponding second reel 22 to retract and release the second rope 23 connected to it, so as to stabilize the robot body 1 from shaking left and right. When the winch 6 drives the robot body 1 to rise or fall, the motors of each second reel 22 are adjusted to control the second rope 23 to be in a taut state to prevent the robot body 1 from shaking left and right.
