[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that, in the description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. The terms "first", "second" and similar words used in the description of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components, and therefore cannot be understood as limiting the present invention.

[0025] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0026] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0027] Figure 1 1 is a schematic structural diagram of the rotary device of the present invention, showing an upper frame 1, a lower frame 2, a slewing bearing 5 and a drive motor 3 of the rotary device.

[0028] like Figure 1-3 As shown, the rotating device includes: an upper frame 1, a lower frame 2, a slewing bearing 5 and a drive motor 3.

[0029] The slewing bearing 5 is located between the upper frame 1 and the lower frame 2. The inner ring of the slewing bearing 5 is connected to the upper frame 1, and the outer ring of the slewing bearing 5 is connected to the lower frame 2. The upper frame 1 and the lower frame 2 are rotatably connected via the slewing bearing 5. The slewing bearing 5 is connected to the upper frame 1 and the lower frame 2 by bolts and nuts.

[0030] The drive motor 3 is installed on the side wall of the upper frame 1. The output end of the drive motor 3 is provided with a drive gear 4, and the outer wall of the outer ring of the slewing bearing 5 is provided with a gear ring. The drive gear 4 at the output end of the drive motor 3 is meshed with the gear ring at the outer wall of the outer ring of the slewing bearing 5.

[0031] As can also be seen from the figure, the rotation device also includes an encoder 6, which is mounted on the side wall of the upper frame 1. The driven gear 7 at the output shaft of the encoder 6 meshes with the ring gear on the outer wall of the outer ring of the slewing bearing 5. Specifically, the drive gear 4 at the output end of the drive motor 3 drives the outer ring of the slewing bearing 5 to rotate, that is, drives the ring gear on the outer wall of the outer ring of the slewing bearing 5 to rotate. The driven gear 7 at the output shaft of the encoder 6 rotates along with the ring gear on the outer wall of the outer ring of the slewing bearing 5. The encoder 6 can determine the rotation angle of the outer ring of the slewing bearing 5, and therefore the rotation angle of the lower frame 2.

[0032] In addition, a protective shell 8 is provided outside the slewing bearing 5 , the drive motor 3 and the encoder 6 , and the protective shell 8 is fixed to the upper frame 1 .

[0033] Furthermore, a limiter 9 is provided at the lower frame 2, and a limit block matching the limiter 9 is provided at the protective shell 8. The maximum rotation angle of the lower frame 2 can be limited by the cooperation between the limiter 9 and the limit block.

[0034] Figure 4 1 is a schematic structural diagram of the plate stacking device of the present invention, wherein the aforementioned rotating device, pulley block and clamp 11 are shown.

[0035] like Figure 4-5 As shown, a pulley block is installed on the top of the upper frame 1, and the pulley block includes a plurality of pulleys 10. In this embodiment, four pulleys 10 are provided. A clamp 11 is provided at the bottom of the lower frame 2. The clamp 11 is used to clamp the steel plate. The clamp 11 is not described in detail here.

[0036] In conjunction with the above embodiments of the present invention, the pulley 10 at the top of the upper frame 1 is connected to the wire rope of the crane, and a clamp 11 is provided at the bottom of the lower frame 2. The crane lifts the plate stack hoist of the present application and moves it to the steel plate. The crane lowers the plate stack hoist, and the clamp 11 clamps the steel plate. The crane drives the plate stack hoist to rise and move it to the position to be adjusted. The drive motor 3 then drives the drive gear 4 to rotate, and the drive gear 4 drives the outer ring of the slewing bearing 5 to rotate, that is, the steel plate clamped by the adjustment clamp 11 rotates, completing the angle adjustment.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
