[0013] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 1 to 3 A bridge type stacking crane is provided, comprising a factory building 1, with a bridge frame 2 running forward and backward in the factory building 1, an electric trolley 3 running left and right on the bridge frame 2, a drum installed on the electric trolley 3, a wire rope 4 wound on the drum, a box body 5 is provided below the electric trolley 3, a pulley block 6 is installed on the top of the box body 5, the wire rope 4 is wound on the pulley block 6, telescopic arms 7 are installed on the front and rear sides of the electric trolley 3, the output end of the telescopic arm 7 is fixedly connected to the box body 5, a plurality of forks 8 are installed at the bottom of the box body 5, a vertical through hole 9 is provided at the front end of the fork 8, a baffle 10 sliding up and down is provided on the left side of the box body 5, and a cylinder 11 corresponding to the through hole 9 above and below is fixed to the bottom of the baffle 10.

[0015] In order to ensure the stability of the baffle 10 sliding up and down, a hydraulic cylinder 12 is installed on the box body 5, and the telescopic end of the hydraulic cylinder 12 is fixedly connected to the upper end of the baffle 10. Guide rods 13 located on both sides of the hydraulic cylinder 12 are fixed on the baffle 10, and the guide rods 13 slide up and down in the box body 5.

[0016] In order to facilitate the inspection of the goods in the box 5 and reduce the weight of the box 5, a plurality of windows 14 are respectively provided on the top surface and three side surfaces of the box 5.

[0017] In order to ensure the stability of the box body 5 and improve safety, a base 15 is fixed at the front and rear ends of the box body 5 , and the output end of the telescopic arm 7 is fixedly connected to the base 15 .

[0018] When the utility model is in use, a trolley running mechanism is installed on both ends of the bridge 2. When the goods in the factory building 1 need to be stacked, a pallet is placed at the bottom of the goods, the trolley running mechanism is started, and the bridge 2 runs in the front and rear directions in the factory building 1. When the bridge 2 runs above the goods, the trolley running mechanism stops, and the electric trolley 3 is started. The electric trolley 3 moves left and right on the bridge 2, and the box 5 moves back and forth, left and right with the electric trolley 3. The box 5 is controlled to move up and down by the wire rope 4. When the box 5 runs to one side of the goods, the hydraulic cylinder 12 is started, and the hydraulic cylinder 12 drives the baffle 10 to move upward, and the baffle 10 moves upward away from the fork 8. At this time, the box 5 is in an open state, and the electric trolley 3 controls the box 5 to move closer to the goods. Multiple forks 8 are inserted to the bottom of the pallet, and the box 5 continues to approach the goods. When the pallet goods completely enter the box 5, the hydraulic cylinder 12 is started again. The hydraulic cylinder 12 drives the baffle 10 and the guide rod 13 to move downward, and the guide rod 13 moves downward in the box 5 to improve the stability of the baffle 10. The baffle 10 drives the cylinder 11 to move downward. When the cylinder 11 is inserted downward into the through hole 9, the hydraulic cylinder 12 stops. At this time, the baffle 10 blocks the goods inside the box 5 to improve the safety of cargo lifting. The wire rope 4 is started, and the wire rope 4 drives the pulley block 6, the box 5 and the goods to move upward as a whole. The telescopic arm 7 is retracted upward. The telescopic arm 7 effectively ensures the overall stability of the box 5 to prevent the box 5 and the goods from tilting or swinging. The box 5 and the goods are moved to a suitable position through the bridge 2 and the electric trolley 3. When the pallet is placed in the stacking position, the hydraulic cylinder 12 controls the baffle 10 to open upward, the box 5 is away from the goods, the fork 8 is pulled out from the bottom of the pallet, and the stacking process is completed, which is cyclically safe and stable.

[0019] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
