Abstract

A twelve-rope container anti-swing mechanism comprises a motor, a speed reducer, a drum, steel wire ropes, fixed pulley blocks, movable pulley blocks and a rope end adjusting and fixing device. The motor, the speed reducer, the drum, the steel wire ropes and the fixed pulley blocks are located on a gantry crane trolley, the movable pulley blocks and the rope end adjusting fixing device are located on a hanger, transverse pitches among the movable pulley blocks on the hanger are enlarged so that the steel wire ropes are transversely obliquely tensioned at small angles, the traveling direction of the trolley has horizontal component force, the arranged direction of the fixed pulley blocks on the gantry crane trolley is perpendicular to the movable pulley blocks on the hanger so that the steel wire ropes are also longitudinally obliquely tensioned at small angles, and the traveling direction of a large vehicle also has horizontal component force. The steel wire ropes are guided out from the drum, are wound through the four movable pulley blocks on the hanger and then are upwards wound through the four fixed pulley blocks located on the gantry crane trolley, rope ends are fixed on the hanger, and the steel wire ropes are triangularly obliquely tensioned after being wound through pulleys. The twelve-rope container anti-swing mechanism overcomes the shortage that a common four-rope winding system is required to be provided with an additional anti-swing device and is high in fault rate, and overcomes shortages that eight-rope winding and sixteen-rope winding anti-swing hoisting mechanisms have large quantities of fixed pulley blocks and are complex in winding forms and high in speed reducer cost.
