Rope climbing robot

The invention discloses a rope-climbing robot, comprising a rack, wherein an arm rotary shaft and a power shaft which are arranged side by side and extend in the lateral direction are rotatablely arranged on the rack. Two arms extending in the radial direction and alternately swaying in a reciprocating manner are arranged on the arm rotary shaft and respectively at the left and right sides of the rack, and one ends of the two arms are respectively provided with hooks which are bent oppositely and hung on a horizontal rope. The two ends of the power shaft are located at the inner sides of the two arms and respectively fixed with first cranks which extend along the radial direction, and first collection rods which extend in the lateral direction are respectively connected between the first cranks and the corresponding arms. The first cranks and the corresponding arms are matched for forming a double-crank rocker mechanism or a crank-sliding block mechanism. The rack is further provided with a power device which is used for driving the power shaft to rotate. The structure of the complete robot is simple, and the horizontal climbing can be realized through alternately reciprocated swaying of the arms. The actions of the robot are flexible and fast.
