The working principle is as follows:
before the robot is used, the robot needs to be installed on a telegraph pole, firstly, a frame of a climbing mechanism 1 and a load-carrying platform 2 are opened, two climbing wheels 20 on a first square frame 11 and a second square frame 12 are respectively positioned on different side pressures of the telegraph pole and are pressed on the outer wall of the telegraph pole, and then the frame of the climbing mechanism 1 is connected with the load-carrying platform 2, so that the robot can be ready to climb upwards on the telegraph pole. The weight of the load-bearing platform 2 presses on the upper ends of the left front upright 13, the right front upright 14, the left rear upright 15 and the right rear upright 16 to drive the left side of the first square frame 11, the right side of the second square frame 12, the right side of the first square frame 11 and the left side of the second square frame 12 to be folded together, so that the two pairs of climbing wheels 20 on the first square frame 11 and the second square frame 12 are matched to hold the telegraph pole tightly all the time.
When climbing, climbing gear motor 21 drives two initiative climbing wheels 20 subtend downwardly rotating above square frame 11 and square frame two 12, and two driven climbing wheels 20 of below also can subtend downwardly rotating, produce frictional force on the surface of wire pole, make climbing mechanism 1 drive load platform 2 and upwards climb, the left platform 24 and the right platform 25 of load platform 2 also can subtend draws in gradually. Meanwhile, under the control action of the control device, the first electric pull rod 22 and the second electric pull rod 23 can be gradually tightened along with the rotation of the climbing wheels 20, so that the two pairs of climbing wheels 20 have enough pressure and clamping force on the outer wall of the telegraph pole, and the climbing mechanism 1 is ensured to drive the load-bearing platform 2 to safely climb upwards on the telegraph pole. When whole device climbed upwards, the safety device between the left platform 24 of load platform 2 and the right platform 25 also can play the locking effect in step, prevents that the left platform 24 and the right platform 25 of load platform 2 from outwards separately, when the adaptation wire pole is more thin more up, also can prevent to climb unexpected tenesmus of mechanism 1 and load platform 2, plays the safety guarantee effect.
After the robot rises to a proper height, personnel and equipment carried on the load platform 2 can maintain and overhaul the power system.
When descending, firstly, the control handle is utilized to open the safety device, the climbing speed reduction motor 21 can be controlled to rotate reversely, and meanwhile, the first electric pull rod 22 and the second electric pull rod 23 are controlled to gradually relax, so that the climbing mechanism 1 drives the load platform 2 to climb downwards along the telegraph pole until the ground is descended.
