Embodiment 1
[0030] exist figure 1 In the schematic diagram of the anti-shake device of the crane shown, the pull block 8 is a rectangular frame, such as image 3 As shown, three pulleys with the same structure are sequentially arranged in a rectangular frame through shafts, and the moving block pulley 9 and two load pulleys 10 are jointly arranged on the hook to form a pulley block, such as Figure 5 Shown; The drag cable driving device 3 in the drag cable mechanism is located at the bottom of the middle part of the crane boom 15, and one end of the drag cable 6 is fixed on the winch of the drag cable driving device, and its other end is drawn from the drag cable driving device, bypassing The fixed pulley located under the load cable driving device 4 at the top of the crane arm bypasses the pulley in the middle of the pull block, then bypasses the movable pulley of the pull block, and is finally fixed on the rectangular frame of the pull block;

Embodiment 2
[0040] Such as Figure 6 , Figure 7 and Figure 8 As shown, the pull block 8 is a rectangular frame, two pulleys with the same structure are arranged side by side in the rectangular frame through the shaft, two load pulleys 10 with the same structure are arranged on the hook 21, and the cable drive device 3 in the cable mechanism Located below the middle part of the crane arm 15, one end of the cable 6 is fixed on the winch of the cable drive device, and the other end is drawn out from the cable drive device 3, bypassing the fixed pulley located under the front part of the crane arm, Pass through the pulley on the left side of the pull block, then pass through two load pulleys 10, and finally be fixed on the rectangular frame of the pull block; At the front of the crane arm, the lower end of the cylinder of the load cable actuator in the load cable actuator is fixedly connected to the crane arm, the upper end of the cylinder is connected to the lower end of the load cable a...
Embodiment 3
[0045] Such as Figure 9 As shown, a column is provided on the base of the crane, and a pair of hoisting cable drive devices are provided at the top of the column, and one end of the two hoisting cables 16 is respectively drawn from the two hoisting cable drive devices at the top of the column, and the other ends are respectively Be fixed on the top of both sides of the front part of the crane arm, one end of the two wing-shaped support frame load-bearing cables 17 is fixedly connected with the middle part of the hoisting cable respectively, and its other end is connected with the two ends of the wing-shaped support frame 2 respectively. The boom of the crane is lifted by the hoisting cable, and the left and right wing-shaped support frame load-bearing cables are used to balance the tension of the wing-shaped support frame by the drag cables, reduce the deformation of the wing-shaped support frame, and make the force more reasonable.
