Positioning pin device of folding arm type lifting equipment

Abstract

The invention provides a positioning pin device of folding arm type lifting equipment. The positioning pin device comprises a hanging bracket, wherein two or more positioning pin sets are arranged onthe hanging bracket. The vertical center line of the positioning pin sets relative to the bottom surfaces of the positioning pin sets coincides with the vertical center line of the hanging bracket relative to the top surface of the hanging bracket. The positioning pin sets have the same structure and size. Each set of the positioning pin sets includes four positioning pins arranged in a rectangular shape, every two positioning pins on one side are disposed on a first pin seat, and every two positioning pins on the other side are arranged on a second pin seat. When lifting more than two boxes of cargo arranged side by side, the folding arm type lifting equipment does not need to move after lifting arms lift one box of cargo, and the lifting arms are capable of directly lifting another box of cargo, so that the efficiency of lifting is greatly improved; and the positioning pins are arranged in a rectangular shape, and a swing frame matched with the positioning pins is further rectangular, so that the structural shape of the swing frame corresponds to the structural shape of a container, and the swing frame is evenly stressed when the lifting arms lift the hanging bracket and the cargo through the swing frame.

Description

technical field [0001] The invention relates to box transport and hoisting equipment, in particular to a positioning pin device for folding arm hoisting equipment. Background technique [0002] When transporting batches of goods, in order to ensure the safety of the transportation process and the convenience of transshipment, the goods are generally packed into boxes for transportation. For example, ocean shipping generally uses general-purpose containers to transport goods. When transporting specific goods Specific cabinets can be made according to the needs. The lifting of the cabinet on land generally uses a reach crane or an ordinary telescopic boom crane. The crane grabs the cabinet through the cabinet arm and lifts the cabinet through the movement of the cabinet. Transport to the transport vehicle or stack the boxes; in large ports, gantry cranes or mobile cranes are generally used to lift the boxes between the wharf and the box freighter; When lifting the box with a ...
