Crawling method of bridge cable detection robot

The invention relates to the technical field of bridge cable detection, in particular to a bridge cable detection robot crawling method, and a bridge cable detection robot comprises a first crawling mechanism, a second crawling mechanism and a crawling driving mechanism. When one of the first crawling mechanism and the second crawling mechanism clamps the bridge inhaul cable, the other one moves along the bridge inhaul cable under the driving of the crawling driving mechanism, so that the bridge inhaul cable is alternately clamped and moves along the bridge inhaul cable, the bridge inhaul cable detection robot can climb along the bridge inhaul cable, and the robot is convenient to control and high in practicability. In addition, the bridge cable detection robot is simple in structure, use of parts is reduced, the size is reduced, and the weight is reduced. Besides, the first crawling mechanism and the second crawling mechanism adopt a walking and stopping climbing mode, so that the vibration of the crawling d
