Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0016] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1-Figure 2 As shown, a crane with high load-bearing capacity includes a frame 1. A hanger 2 is arranged on the frame 1. A hanger 3 that can rotate around the top of the hanger 2 is arranged on the hanger 2. A pay-off drum 4 is arranged on one side of the hanger 3. The pay-off drum 4 can be used to release and reel in a cable 5. The pay-off drum 4 is connected to a hook 6 through the cable 5. A sliding frame 7 is connected to one side of the hook 6. The sliding frame 7 is slidingly connected to the hanger 3. An output shaft 8 is connected to one side of the sliding frame 7. The output shaft 8 is connected to a cylinder 9. When the cylinder 9 is working, the output shaft 8 can be driven to move, thereby driving the sliding frame 7 on the hanger 3 to move back and forth.

[0019] A hydraulic cylinder 10 for rotating the hanger 3 is provided on one side of the hanger 3. The hydraulic cylinder 10 can be used to lift the hanger 3, thereby adjusting the position of the hanger 3.

[0020] The core technical solution of this application is as follows:

[0021] The output shaft 8 is fixedly connected with a driving rod 11. A connecting rod 12 is connected to the bottom of the driving rod 11. A gear rod 13 is connected to the bottom of the connecting rod 12. The gear rod 13 is meshed with a gear 14. The bottom of the gear 14 is meshed with a gear rod 2 15. The gear rod 2 15 is connected to a bearing plate 16.

[0022] The bottom of the bearing plate 16 is slidably connected with a bracket 17. The bracket 17 is fixedly connected to the frame 1. The gear 14 is bearing-connected with a column 18. The column 18 is fixedly connected to the frame 1.

[0023] As mentioned above, when the output shaft 8 drives the hook 6 to move outward to the position of the designated cargo, the driving rod 11 and the connecting rod 12 drive the gear rod 13 to move outward. At this time, the gear 14 rotates, so that the movement direction of the gear rod 2 15 is opposite to that of the gear rod 1 13, and the gear rod 2 15 moves inward, thereby driving the supporting plate 16 to move inward.

[0024] Overall working process:

[0025] 1. Move the crane to the side of the designated cargo, the output shaft 8 drives the hook 6 to move above the cargo, and the wire drum 4 releases the wire, so that the hook 6 suspends the cargo;

[0026] 2. The wire reel 4 reels in the wire and suspends the cargo on the hook 6. At this time, the output shaft 8 is retracted, so that the hook 6 moves toward the inside of the frame 1, and the gear rod 15 moves outward, thereby driving the load-bearing plate 16 to move outward until it abuts against the bottom of the cargo, so that part of the weight of the cargo is borne by the load-bearing plate 16, reducing the pressure on the hook 6;

[0027] 3. Move the crane so that after the crane moves the cargo to the designated location, the output shaft 8 moves outward, thereby causing the gear rod 2 15 to move inward, and the cargo is separated from the load-bearing plate 16, and then the cargo is released, thereby improving the cargo-bearing capacity, preventing the hook 6 from being damaged or the cable 5 from being broken, and extending the service life.

[0028] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
