Description

Pallet cargo transferring and falling machine with unlimited transferred cargo height in pit

Technical Field

The invention relates to a tray cargo transferring and falling machine, in particular to a tray cargo transferring and falling machine which is arranged in a pit and is not limited in the height of transferred cargo.

Background

In automated logistics warehousing, the transfer of goods largely uses automated logistics transport equipment; on the same horizontal plane of commodity circulation conveying, when carrying out the transportation of goods between transfer chain and the manual car of using of standard, often meet the condition that highly being higher than the manual car working face of using of standard of the conveying working face of automatic transfer chain, in order to realize the transportation of goods on the working face of co-altitude not, on-the-spot solution generally has two kinds: the first method is realized by a forklift, namely, the goods on a standard manual carrying vehicle are transferred to the forklift, and then the forklift transfers the goods to an automatic conveying line by lifting a fork body, so that the forklift needs to be configured, and special operators need to be configured on site; the second is to arrange a lifter, namely, the lifter is arranged between a standard manual carrying vehicle and an automatic conveying line, and the lifter is commonly called as a tray cargo transferring and falling machine to realize the transfer of the cargo; the tray cargo transferring floor machine is generally composed of a left portal frame and a right portal frame, a Y-shaped fork-type lifting roller bed is arranged between the two portal frames, a standard manual transport vehicle transports cargos to the fork-type lifting roller bed between the two portal frames, then the cargos are transferred to the fork-type lifting roller bed, the fork-type lifting roller bed is lifted, the cargos are lifted to the working surface of an automatic conveying line, rollers on the roller bed are started, and then the cargos are conveyed to the automatic conveying line; the lifting and landing of fork type lifting roller bed are jointly born by two lifting chain mechanisms on a left portal frame and two lifting chain mechanisms on a right portal frame, the four lifting chains are generally driven by a driving motor, the driving motor is generally arranged at the left portal frame, the power of the lifting chain mechanisms on the right portal frame needs a synchronous transmission mechanism of left power to transmit the driving force from the left side to the right side, so that the synchronous lifting of the lifting chains at the left and right sides of the lifting roller bed is realized, a transversely-connected synchronous sprocket shaft is generally arranged between the tops of the two portal frames to realize the synchronous transmission of the left lifting power to the right portal frame, the transversely-connected sprocket synchronous lifting transmission shaft of the tray cargo transferring and landing machine is arranged, and when the transferred cargo moves longitudinally, the height of the transferred cargo cannot exceed the height of the left lifting chain mechanisms on the left portal frame, The chain wheels which are arranged at the top ends of the right two portal frames and transversely connected with each other synchronously lift the transmission shaft, so that the defect that the height of the transported goods is limited is brought; in addition, in an on-site warehouse, the high-altitude structure of some warehouses is limited, so that the chain wheels which are transversely connected and arranged between the tops of the two gantry frames can not be synchronously lifted and transferred, and the chain wheels can not be arranged; in addition, the synchronous lifting transmission devices on the left portal frame and the right portal frame are arranged at the high positions of the top ends of the portal frames, and the defect of difficult maintenance is also existed.

Among the existing warehouse, on the same horizontal transfer face of commodity circulation, when adopting the tray goods to transport the machine that falls, between automatic conveying line and the manual car of removing of standard, when realizing the mutual transportation of goods, some places are the requirement: the ground on which the standard manual carrying vehicle runs is to be on the same horizontal plane with the installation ground of the automatic conveying line, and no obstacle can be generated in the longitudinal direction of cargo conveying, and the requirement of the site condition causes that the tray cargo transferring floor machine adopting a lifting driving motor has difficulty in the cross-longitudinal arrangement of a synchronous transmission shaft, how to realize on the same horizontal logistics conveying surface, the bottom surface is free of obstacle during longitudinal conveying, and the height of the conveyed cargo is not limited, so that the ground is a problem to be solved on site.
