Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle loading equipment, and in particular relates to a vertical large-stroke adjustment mechanism and a vehicle loading machine. Background Art

[0002] Existing loading equipment needs to carry out loading operations in the carriage, and its output end needs to have the ability to adjust the height vertically in order to realize the function of placing goods layer by layer.

[0003] For example, the loading equipment disclosed in Chinese patents CN 214059249 U and CN 115783789 A has a vertical height adjustment method in which the input end of the intermediate conveyor rotates around a fixed fulcrum to adjust the height of the output end. However, the existing loading equipment drives the intermediate conveyor to rise and fall by arranging a retractable electric cylinder or electric push rod under the intermediate conveyor.

[0004] Since the cylinder of the electric cylinder needs to rotate around the support point, the swing amplitude of the intermediate conveyor is limited, which in turn limits the vertical travel of the output end, making it difficult for the lower limit position of the output end to be lower than the position of the cylinder support point. Therefore, the output end cannot be close to the bottom of the carriage, and there is a risk of damage when placing goods. Usually, the conveyor at the end needs to adjust its own height for compensation, which makes the structure of the equipment complicated.

[0005] Furthermore, in the loading machine disclosed in Chinese patent CN 220165258 U, the conveyor at the end is located lower than the middle conveyor. When placing goods close to the top of the carriage, the output end of the middle conveyor reaches the top of the carriage first, while the conveyor at the end is still some distance away from the top of the carriage, making it difficult to place the goods close to the top of the carriage, resulting in idle space waste.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
