Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and embodiments.
Shown in Figure 1, the embodiment of the present invention provides a kind of weight crane barge anti-oscillation device, including：At least three turn to cunning
Wheel 5, and each angle pulley 5 is uniformly distributed in 4 periphery of weight, each angle pulley 5 is respectively connected with one and only puts hawser 3,
3 one end of the only pendulum hawser passes through the angle pulley 5 and is connected on weight 4, and 3 other end of only pendulum hawser connection one is slided
Wheel group 1, and the free end of the pulley blocks 1 is connected with mass 2.Pulley blocks 1 include at least one fixed pulley 11, at least one
Movable pulley 12 and at least a transmission rope 13, transmission rope 13 pass through fixed pulley 11 and movable pulley 12.Power is changed according to fixed pulley 11
Direction, movable pulley 12 change power size principle, the present invention by angle pulley change power direction, changed by pulley blocks
The gravity of 2 vertical direction of mass is converted into lateral pulling force and is applied to and treats crane barge lifting by the direction of variable force and size
Weight 4 adjusts the pulling force size that only pendulum hawser 3 applies by adjusting weight or the pulley blocks 1 of mass 2, lifts crane barge
During weight 4, the horizontal dynamic balance for all directions that weight 4 is subject to only puts effect so as to reach.
Preferably, pulley blocks 1 include two fixed pulleys, 11, movable pulleys 12 and a transmission rope 13.Referring to Fig. 2 institutes
Show, pulley blocks 1 include fixed pulley A111, fixed pulley B112, movable pulley A121 and a transmission rope 13；13 one end of transmission rope connects
Mass 2, the other end sequentially pass through the combination of fixed pulley B112, fixed pulley A111 and movable pulley A121；Only 3 one end of pendulum hawser connects
Weight 4 is connect, the other end passes through the center of the connection movable pulley of angle pulley 5 A121.The combination of this angle pulley 5 plus pulley blocks 1
The gravity of 2 vertical direction of mass can be converted into lateral pulling force and be applied to the weight 4 for treating crane barge lifting, due to wherein dynamic
The effect of pulley 12, the every pulling force only put on hawser 3 are N times of 2 weight of mass, and N is bypasses rope on movable pulley 12
Quantity.The present invention adjusts the pulling force size that only pendulum hawser 3 applies by adjusting 2 weight of mass or pulley blocks 1.
It is shown in Figure 3, it is preferred that weight crane barge anti-oscillation device includes four angle pulleies 5, four only 3 and of pendulum hawser
Four groups of pulley blocks 1.Four are only put the quadrangle that hawser 3 connects weight 4 respectively.At this point for the flat of crane barge lifting rectangle weight 4
Weigh best results.
Weight crane barge anti-oscillation device work step of the present invention is as follows：
