Abstract

A joist barrow type dumping system stabilizing device for freighters belongs to heeling preventing devices for large-sized freighter dumping systems, and is designed in combination of hydraulic principle and force balancing principle. Combination rails are welded to two sides of a deck, a joist barrow is mounted on the rails, the length of each joist barrow wheel axle is prolonged to force a corresponding joist barrow wheel to be able to move only along the extension direction of the combination rails, and when the joist barrow sways left and right along a freighter, heeling force is decomposed by clamping rails for pulling upward and pressing downward so that the joist barrow is integrated with a freighter body without tilting. Weight of cargo lifted by the joist barrow is effectively decomposed by inner splayed props and outer splayed props, and structural strength of a frame of the joist barrow when the freighter body sways left and right is enhanced. The difficulty that a common joist barrow used for unloading cargos from a large-sized freighter is easy to tilt as the freighter sways left and right in wind and waves is overcome, cargos are directly transferred to small boats offshore at anchorage, and transport time is saved and cost is reduced. The joist barrow type dumping system stabilizing device is simple in structure, low in cost, convenient in mounting and safe in operation.
