Conveyor with multi-bar mechanisms

Abstract

The invention discloses a conveyor with multi-bar mechanisms. The conveyor comprises a portal fame system, a multi-bar mechanism conveying arm rest, an arm rest support, a double-cylinder winch, a carrier roller unit and an automatic control system. The portal frame system, the double-cylinder winch and the arm rest support are mounted on a deck of a hull. The conveying arm rest is of a motion-convertible multi-bar structure and is provided with carrier rollers. The rear section of the conveying arm rest is hinged to the arm rest support. The double-cylinder winch is connected with the multi-bar mechanism conveying arm rest through a steel wire rope via a portal frame pulley set. A hydraulic device and a control device are mounted between every two adjacent multi-bar mechanisms. A tensionsensor is mounted at the tail end of the steel wire rope. The whole conveyor is controlled through an automatic control system. Full-course contraction of the conveying arm rest of the conveying arm rest of the conveyor can be achieved through the automatic control system. When the conveying arm rest contracts, the influence of the conveying arm rest on the balance of the hull is small, the self weight of a conveying arm is low, the extension distance of the conveying arm is long, a belt is automatically tensioned, and installation and operation are easy and convenient; and after the conveyingarm rest contacts, the advantages of small occupied space, high safety, wide conveying range and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of transport ship conveyors, in particular to a multi-bar mechanism conveyor. Background technique [0002] In recent years, inland river sand unloading ships have received extensive attention for their flexible and fast unloading of cargo, but their instability problems have become increasingly prominent. Moreover, our country has vast waters and abundant water transportation resources. Inland river self-unloading sand ships are widely used, and its industry is also in a period of vigorous development. However, the conveying boom of the traditional self-unloading sand ship can reach more than 40 meters, but it is often impossible to recover, resulting in poor stability and a great potential safety hazard. For example, due to the high accident rate of traditional outrigger belt racks, domestic insurance companies have jointly refused insurance for belt racks. [0003] Therefore, in order to solve the techn...
