Problems solved by technology

[0004] In the actual situation, when the traveling device walks on the photovoltaic string, it is affected by factors such as the difference in the driving force of the upper and lower traveling wheels or the difference in the track surface, which leads to the fact that the upper and lower traveling wheels cannot walk according to the predetermined displacement during the walking process of the traveling mechanism, which is prone to "up and down". When this situation occurs during climbing, the positions of the four wheels corresponding to the tracks are not on the same plane, resulting in differences in the support and friction of the four wheels. Unable to normally drive the equipment to skew or even derail, and the frame is forced to twist and deform, which seriously affects the service life
