Foldable five-section suspension arm device for containers

The utility model discloses a foldable five-section suspension arm device for containers, and aims at providing the suspension arm device capable of meeting the requirement for loading and unloading the containers on both sides in the unfolding state, and meeting the requirements of railroad transportation laws and regulations of China after the containers are loaded. The outer part of a guide post is sheathed with a vertical part of a T-shaped lifting arm; the T-shaped lifting arm is connected with a lift driving mechanism; foldable horizontal unfolding arm mechanisms are respectively hinged with the both sides of a horizontal part of the T-shaped lifting arm; the foldable horizontal unfolding arm mechanisms comprise rotating arms, unfolding arms, unfolding driving mechanisms, first link mechanisms and second link mechanisms; the rotating arms are hinged with the horizontal part of the T-shaped lifting arm; the unfolding arms are respectively hinged with the rotating arms and the horizontal part of the T-shaped lifting arm through the second link mechanisms; two ends of each first link mechanism are respectively hinged with each rotating arm and the lower part of the vertical part of the T-shaped lifting arm; the unfolding driving mechanisms are connected with the vertical part of the T-shaped lifting arm; and drive rods of the unfolding driving mechanisms are hinged with the first link mechanisms. The foldable five-section suspension arm device for the containers has the advantages of convenient controlling and safe and reliable operation.
