The front driving wheel 23 stops moving, the rear driving wheel 23 is driven by the locking wheel driving motor 20 through the safety mechanism 5, the locking lever is pulled down, the locking wheel is in contact with the electric wire, and therefore the locking lever and the driving wheel 23 act together, the clamp inspection robot is prevented from slipping. Meanwhile, due to the special structure of the locking wheel, the robot can be kept to topple in the front-back direction.
And (2) a process: the safety mechanism 5 of the front driving wheel 23 is released
After the rear driving wheel 23 is locked, the safety gear 5 of the front driving wheel 23 is rotated 90 degrees counterclockwise, so that the front safety gear 5 is released.
And 3, process: the front driving wheel 23 is lifted while rotating by 90 °
The front driving wheel 23 is locked by the joint motor 7 after rising to a certain angle through the front four-bar linkage 3, and then the four-bar linkage base joint motor 7 rotates 90 degrees outwards.
And 4, process: the safety gear 5 of the rear driving wheel 23 is released, while the rear driving front wheel advances
And (5) a process: rear drive wheel 23 is locked
After the rear driving wheel 23 has advanced close to the obstacle, the safety gear 5 of the rear driving wheel 23 locks.
And 6, a process: the front driving wheel 23 returns to the locking position

The locking mechanism of the front driving wheel 23 is released and the front driving wheel 23 is advanced to the proper position.
And a process 9: the rear driving wheel 23 returns to the electric line and the obstacle crossing is finished
After the front driving wheel 23 runs to a proper position, the safety mechanism 5 of the front driving wheel 23 is locked to prevent the inspection robot from sliding integrally, the rear driving wheel 23 rotates 90 degrees along the pointer, then the four-bar mechanism 3 lowers the proper position to enable the driving wheels 23 on the two sides to fall on the power transmission line, and then the safety mechanism 5 of the rear driving wheel 23 rotates 90 degrees clockwise, so that obstacle crossing is completed. The forward movement can be continued after the safety gear 5 of the front driving wheel 23 is released.
Obstacle crossing size parameters are given for different obstacles. The types of obstacles mainly include: a vibration damper, a connecting ring, a spacer, a suspension clamp, an insulator, a telegraph pole and the like.
The obstacles are the largest in size of the utility pole, and therefore, the obstacle crossing manner of the vibration damper, the connection ring, the spacer, the suspension clamp and the insulator can be referred to the obstacle crossing manner of the utility pole.
