The invention discloses a hooped mine elevator patrol robot mechanism based on electromagnetic chucks. The hooped mine elevator patrol robot mechanism is integrally divided into an upper mechanical hand part and a lower mechanical hand part which are the same in structure. The two mechanical hand parts are connected through a slider-crank mechanism and a sliding rod-slider mechanism. The two mechanical hand parts are used for alternately hooping an elevator stand column, meanwhile, the slider-crank mechanism and the sliding rod-slider mechanism are combined for achieving alternate ascending of the two mechanical hand parts, and therefore the overall movement of a robot is achieved. All joints are connected in series by the mechanical hand parts through a steel wire rope, and all the joints are connected by the mechanical hand parts through springs. The electromagnetic chucks are arranged on the joints. The steel wire rope is driven through a winch motor to be tensioned and loosened. Under the effect of the restoring force of the springs and with the combination of electricity obtaining and losing of the electromagnetic chucks, mechanical claws are controlled to be opened and closed. The hooped mine elevator patrol robot mechanism is simple and light in structure, flexible in action and high in hooping force, the requirement for power of a motor can be effectively lowered, and the phenomenon that that spray paint or a protection layer on the surface of a cable or a steel material of the elevator is damaged is effectively avoided.
