Description

Cargo lift with horizontal transfer device

Technical Field

The invention belongs to the technical field of cargo transportation equipment, and particularly relates to a cargo lift with a horizontal transfer device.

The invention belongs to intelligent port loading and unloading equipment of 2.1.5 intelligent logistics equipment in the key direction of 2.1 intelligent manufacturing equipment industry in the 2 high-end equipment manufacturing industry of strategic novel industry catalogue.

Background

When goods need be transported at the level difference such as between the landing, usually need the goods lift machinery to accomplish, traditional goods lift usually needs the car to arrive fixed target landing after, will wait to transport the goods and load the car through manual handling or manual manipulation fork truck, or lift the goods in the car, when the shipment volume is great, need consume a large amount of man-hours, and manual manipulation fork truck sends the goods into the car in-process, the lateral wall of car is scratched by goods or fork truck easily, this kind of traditional goods lift does not have horizontal transfer device, the function is single, inefficiency, the clearance between its car and the landing ground is less relatively, only be applicable to the landing and the good condition of car butt joint and use. For some special environments, such as wharfs, conventional cargo lifts have significant limitations. Limitations of conventional cargo lifts and material transfer factors affecting specific environments such as wharfs are as follows:

1. and (5) stopping the fixed landing: conventional cargo lifts are typically designed for fixed landing stops, i.e. the car can only stop between predetermined floors. This design is suitable for the conventional environment such as building, but in special environment such as wharf, the unloading and loading points of goods may be at different heights and positions, and cannot be adapted simply by fixing the landing stop.

2. Height and distance float: the difference between the water level of the quay, the tonnage of the berthing vessel and the different vessels results in a large floating range of heights and distances between the unloading and loading points. Conventional cargo lifts are difficult to accommodate such height and distance variations, require constant adjustment and retrofitting, and add to the complexity and cost of operation.

3. Rely on boarding ladders and manual forklifts: in special environments such as wharfs, boarding ladders and manual forklifts are commonly used to accommodate the small range of material transfer requirements. This approach, while flexible, is inefficient in a wide range of floating conditions and presents a certain safety risk.

4. The mechanized automation operation is limited: limitations of conventional cargo lifts limit the development of mechanized and automated operations. In the case of large-range distance floats, highly automated material transport is difficult to achieve, which generally requires more manual intervention and operation.

5. Influence the material transfer efficiency: the problems are combined, and the limitation of the traditional goods lifter seriously affects the efficiency and the safety of material transfer in special environments such as wharfs. This can result in significant impact on the vertical and horizontal transfer of materials between the vessel and the dock, increasing time and resource waste.
