DEVICE TO LOAD LOOSE CARGOES INTO FREIGHT SHIP HOLDS Russian patent published in 2008 - IPC B65G67/02 B65G67/60 B65G63/00 

FIELD: loading-unloading means.

SUBSTANCE: device to load loose cargoes into the ship holds incorporates a trestle with columns (7), loading chute (8) to receive loose cargo from the pneumowheel transport dump vehicle arranged to move all along the loading site width and hinged to rectangular flat frame (13) coupled with the said chute by power cylinders. The loading chute motion mechanism is formed by an infinite flexible element enclosing, by means of a drive and tension units, the trestle columns with a clearance and clamped on the said rectangular flat frame by grips (25). The aforesaid rectangular flat frame is furnished, in its top, with vertical rollers (18) and, at its bottom, horizontal rollers (20) interacting with guides (19) and (21) fixed at the trestle columns, respectively. The said frame incorporates a light device to locate the loading chute position within the limits of the loading site. The position of the flexible elements grips is selected from the expression W₁l₁=W₂l₂, where W₁ W₂ is the resistance to motion on the guides of the upper and lower rollers, respectively, caused by weight loads from the frame and the chute, l₁, l₂ are distances from the grips to the upper and lower rollers, respectively.

EFFECT: simpler design and control.
