[0034] Currently, in the box - type two - way opening cargo lifting device at the cruise terminal, a large amount of manpower is required for the stacking and transfer of goods, and the mechanized conveying part is less. The connection capacity of cruise ships and vessels is relatively limited.

[0035] Based on this, the embodiments of the present disclosure provide a box - type cargo transfer device, including a main beam body, a first displacement mechanism, a second displacement mechanism and a lifting device. The first displacement mechanism is connected to the main beam body, and the first displacement mechanism drives the main beam body to move along the first direction of the car. The lifting device includes a boom and a hoisting mechanism. The boom is connected to the main beam body through the second displacement mechanism, and the second displacement mechanism is used to drive the boom to move along the second direction of the car. The first direction and the second direction of the car intersect; the hoisting mechanism includes a third displacement mechanism and a lifting piece, and the lifting piece is connected to the boom through the third displacement mechanism, and the third displacement mechanism is used to drive the lifting piece to move along the extending direction of the boom. Thereby, it can save manpower, improve the cargo transfer efficiency, realize the mechanized conveying of goods from the terminal to the cruise ship deck, and increase the connection capacity of the terminal for cruise ships.

[0036] The following will detail the box - type cargo transfer device through specific embodiments:

[0037] Refer to Figures 1 to 6As shown in the figure, in the first aspect of the present disclosure, a box-type cargo transfer device is provided, which includes a main beam body 1, a first displacement mechanism 2, a second displacement mechanism 3, and a lifting device 4. The first displacement mechanism 2 is connected to the main beam body 1, and the first displacement mechanism 2 drives the main beam body 1 to move along the first direction of the car 100. Among them, the lifting device 4 includes a boom 41 and a hoisting mechanism 42. The boom 41 is connected to the main beam body 1 through the second displacement mechanism 3, and the second displacement mechanism 3 is used to drive the boom 41 to move along the second direction of the car 100. The first direction and the second direction of the car 100 intersect; the hoisting mechanism 42 includes a third displacement mechanism 421 and a lifting member 422. The lifting member 422 is connected to the boom 41 through the third displacement mechanism 421, and the third displacement mechanism 421 is used to drive the lifting member 422 to move along the extension direction of the boom 41.

[0038] For the first displacement mechanism 2, the second displacement mechanism 3, and the third displacement mechanism 421 of the present disclosure, telescopic structures such as telescopic cylinders and telescopic oil cylinders can be selected for driving, or a lead screw stepping motor can be selected for displacement driving.

[0039] Specifically, the car 100 of the cargo lifting device stops at the dock surface, the car door on the dock surface side is opened, and the forklift carries goods into the car for stacking and unloading. When the goods need to be placed in a position that the forklift cannot reach, the staff operates the first displacement mechanism 2 and the lifting device 4 of the present disclosure in the car with the console, so that the lifting device 4 reaches above the goods. The goods are firmly connected to the lifting member 422 of the lifting device 4 with a sling. The lifting member 422 hoists the goods to an unobstructed height. The first displacement mechanism 2 moves in the first direction inside the car, and the third displacement mechanism 421 drives the lifting member 422 to move in the extension direction of the boom 41, moves the goods to the designated position, and the lifting member 422 descends to unload the goods. It should be noted that the first direction and the second direction of the present disclosure form intersecting X and Y axes, and the included angle formed by the intersection of the first direction and the second direction can be vertical or non-vertical. The movement routes of the first direction and the second direction are adaptively selected according to the type of the car and the needs of the use scenario. Specifically, the first direction of the present disclosure is set to be horizontal inside the car, the second direction is the longitudinal direction inside the car, and the second direction is the direction towards the car door. It can be understood that, as Figure 5 shown, the stroke of the second displacement mechanism 3 is in the extension direction of the main beam body 1. According to the length of the main beam body 1, the boom 41 can be driven by the second displacement mechanism 3 to extend outside the car for cargo transfer. Or the length of the boom 41 can meet the requirements for extending out of the cargo box for hoisting.

[0040] After the goods are loaded on the dock surface, that is, in the car, the main beam 1 of the present disclosure is returned through the first displacement mechanism 2, and the lifting device 4 is returned through the second displacement mechanism 3 to Figure 6The starting position shown. The car 100 of the goods lifting device performs a vertical operation procedure in the hoistway. The car 100 is lowered to the operating height of the cruise ship deck. The car door on the river side is opened. The staff operates the first displacement mechanism 2 and the second displacement mechanism 3 through the operation console. The goods are firmly connected to the hook of the lifting member 422 with rigging. The lifting member 422 hoists the goods to an unobstructed height, and then drives the goods to move through the first displacement mechanism 2 and the second displacement mechanism 3, and moves the goods to the shipping position. Among them, the second displacement mechanism 3 drives the boom 41, the lifting mechanism 42 and the goods to extend out of the car 100 to transfer the goods to the cruise ship deck, and the lifting member 422 lowers the goods for unloading. After the goods loading and unloading are completed, the lifting device 4 is retracted into the starting position in the car 100 through the second displacement mechanism 3, and the car door is closed. Specifically, the boom 41 can be set with an overhanging length according to the distance between the dock and the cruise ship berth.
