| description | The invention relates to the technical field of electric power operation and maintenance equipment, and particularly discloses an anti-falling device and a crawling ladder assembly. The anti-falling device comprises a support assembly. The two sides of the support assembly are each movably provided with one sliding mechanism. The sliding mechanisms can slide relative to a longitudinal rod of a crawling ladder. A locking mechanism is further arranged on the support assembly and arranged between the two sliding mechanisms, and the locking mechanism comprises a movable rod. The movable rod comprises a first end close to the longitudinal rod and a second end away from the longitudinal rod, a locking ring is arranged at the second end, a hinge point is arranged between the first end and the second end, and the movable rod is hinged to the support assembly through the hinge point so that the movable rod can rotate relative to the locking mechanism. When the movable rod rotates to a designedregion, the sliding mecha |
