Power transmission line iron tower climbing adsorption device

The utility model relates to the technical field of power transmission line iron tower climbing robots, in particular to a power transmission line iron tower climbing adsorption device which comprises an adsorption mechanism fixing frame assembly and a magnetic adsorption mechanism assembly installed at the bottom of the adsorption mechanism fixing frame assembly. The adsorption mechanism fixing frame assembly is composed of an electric push rod assembly and a sliding block assembly. The magnetic adsorption mechanism assembly is composed of a sliding fixing frame, a first sliding fixing side plate, a guide rail, a sliding block, a sliding bottom plate, a second sliding fixing side plate, a movable rod connecting shaft and a magnet adsorption assembly. Wherein the magnet adsorption assembly is composed of two spherical hinge structures, so that a magnet at the front end is highly flexible, and it is guaranteed that multiple sets of magnets and tower materials are well adsorbed and attached together.
