Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Shown in Figure 1, the embodiment of the present invention provides a kind of weight crane barge anti-oscillation device, including: at least three angle pulley 5, and each described angle pulley 5 to be uniformly distributed in weight 4 peripheral, each angle pulley 5 is respectively connected to one and only puts hawser 3, described only pendulum hawser 3 one end by described angle pulley 5 lateral extend and connected on weight 4, described only pendulum hawser 3 other end connects an assembly pulley 1, and the free end of described assembly pulley 1 is connected to mass 2.Assembly pulley 1 includes at least one fixed pulley 11, at least one movable pulley 12 and at least one transmission rope 13, and transmission rope 13 passes fixed pulley 11 and movable pulley 12.The direction of power is changed according to fixed pulley 11, movable pulley 12 changes the principle of the size of power, the present invention changes the direction of power by angle pulley, direction and the size of power is changed by assembly pulley, the gravity of mass 2 vertical direction is converted into lateral pulling force and puts on the weight 4 treating that crane barge lifts, the pulling force size that only pendulum hawser 3 applies is regulated by the weight or assembly pulley 1 regulating mass 2, make in crane barge lifting weight 4 process, the horizontal force balance of all directions that weight 4 is subject to, thus reaching only to put effect.
Preferably, assembly pulley 1 includes 11, movable pulley 12 of two fixed pulleys and a transmission rope 13.Shown in Figure 2, assembly pulley 1 includes fixed pulley A111, fixed pulley B112, movable pulley A121 and a transmission rope 13；Transmission rope 13 one end connects weight 4, and the other end sequentially passes through the combination of fixed pulley B112, fixed pulley A111 and movable pulley A121；Only pendulum hawser 3 one end connects weight 4, and the other end connects the center of movable pulley A121 through angle pulley 5.This angle pulley 5 adds the combination of assembly pulley 1 and the gravity of mass 2 vertical direction can be converted into lateral pulling force and put on the weight 4 treating that crane barge lifts, effect due to wherein movable pulley 12, every is stopped the pulling force put on hawser 3 and is N times of mass 2 weight, and N is the quantity walking around rope on movable pulley 12.The present invention regulates, by regulating mass 2 weight or assembly pulley 1, the pulling force size that only pendulum hawser 3 applies.
