[0024] The hydraulic rod 7 in this example is symmetrically distributed about the center of the first movable plate 8, and the first movable plate 8 is slidably connected to the limiting groove 6. The above structural design enables the hydraulic rod 7 to stably drive the first movable plate 8 to move linearly along the limiting groove 6.

[0025] The top view width of the first damping block 9 is greater than 3 / 4 of the top view width of the first movable plate 8, and the top view width of the first movable plate 8 is greater than 3 / 4 of the top view width of the positioning sleeve 5. The above structural design ensures sufficient connection stability between the first movable plate 8 and the positioning sleeve 5, and ensures sufficient end face area of ​​the first damping block 9.

[0026] The horizontal gear 11 is symmetrically distributed about the center of the first movable plate 8. The center of the first movable plate 8 and the center of the horizontal gear 11 are on the same horizontal plane.

The first damping block 9 is separated from one side of the hanging beam body 3, and the hydraulic rod 7 is controlled to stop working. While the first movable plate 8 is displaced, the second movable plate 12 is driven by the horizontal gear 11 and moves linearly along the stabilizing card plate 14 in the direction of the guide support frame 1. The second damping block 16 is separated from the other side of the hanging beam body 3. After the hydraulic rod 7 stops working, the first movable plate 8 locks the second movable plate 12 through the horizontal gear 11 to ensure that the first damping block 9 and the second damping block 16 do not contact the hanging beam body 3. This is the working principle of the accumulation chain hanging beam damping device.
