[0002] A crane is a multi-action lifting machine used for vertically lifting and horizontally moving heavy objects; it is commonly referred to as a hoist or overhead crane. It mainly includes various types such as tire cranes, bridge cranes, and crawler cranes, and is widely used in ports, workshops, construction sites, and other locations. The working characteristic of a crane is intermittent motion; that is, in a work cycle, the corresponding mechanisms for actions such as picking up, moving, and unloading materials work alternately.

[0003] When a crane is in operation, the heavy objects to be moved are mainly tied with steel cables, which are then suspended from the crane's hook. To facilitate the lifting and lowering of the hook, ropes are generally used to install the hook on the crane. However, because ropes are lightweight and highly flexible, the crane is prone to swaying during the handling of heavy objects, which poses certain safety hazards. Utility Model Content

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown, in this embodiment, a crane anti-sway control device includes a mounting box 1, with an anti-sway component 2 fixedly connected to the left side of the mounting box 1. The anti-sway component 2 includes a protective shell 201, with a first motor 202 fixedly connected to the side of the protective shell 201 away from the mounting box 1. The output end of the first motor 202 is fixedly connected to a drive rod 203, and a drive wheel 204 is fixedly sleeved on the surface of the drive rod 203. A belt 205 is provided on the surface of the drive wheel 204, and a transmission wheel 206 is provided on the side of the belt 205 away from the drive wheel 204. A transmission rod 207 is fixedly connected to the inner wall of the transmission wheel 206, and a first take-up roller 208 is fixedly sleeved on the surfaces of both the transmission rod 207 and the drive rod 203. A first rope 209 is provided on the surface of the first take-up roller 208, and a connecting box 210 is fixedly connected to the front and rear sides of the mounting box 1.

[0023] By starting the first motor 202, the drive rod 203 drives the drive wheel 204 to rotate. The belt 205 transmits power to the transmission wheel 206, causing the transmission rod 207 to rotate. This, in turn, drives the first take-up roller 208 to rotate, thereby winding and unwinding the first rope 209. During the process of the hook 9 moving heavy objects, the four corners of the connecting plate 7 are fixed by the four first ropes 209, which increases the stability during movement. At the same time, the first ropes 209 can distribute the weight of the heavy objects evenly, thereby reducing the load on the second rope 6 and improving its service life.

[0024] The drive rod 203 and transmission rod 207 are rotatably connected to the connecting box 210. The drive wheel 204 and transmission wheel 206 are located inside the protective housing 201. There are two first winding rollers 208. The first rope 209 passes through the connecting box 210 and extends to its outside.

[0025] A second motor 3 is fixedly connected to the side of the mounting box 1 away from the protective shell 201. A rotating rod 4 is fixedly connected to the output end of the second motor 3. A second take-up roller 5 is fixedly sleeved on the surface of the rotating rod 4. A second rope 6 is provided on the surface of the second take-up roller 5. A connecting plate 7 is fixedly connected to the bottom end of the second rope 6. A lifting lug 8 is fixedly connected to the top end of the connecting plate 7. A hook 9 is fixedly connected to the bottom end of the connecting plate 7.

[0026] By starting the second motor 3, the rotating rod 4 drives the second winding roller 5 to rotate, thereby winding and unwinding the second rope 6, and lowering the hook 9 to a suitable height, which facilitates the installation and movement of heavy objects. In addition, the second rope 6 has a certain deformation capacity, which makes it easy to store.

[0027] There are four lifting lugs 8, which are located at the four corners of the connecting plate 7 and are in contact with the first rope 209.

[0028] The top of the mounting box 1 is fixedly connected to a movable frame 10, and the top of the movable frame 10 is slidably connected to a crossbeam 11. Mounting grooves 12 are provided on the front and rear sides of the crossbeam 11, and guide rail grooves 13 are provided on the front and rear sides of the crossbeam 11.

[0029] A third motor 14 is fixedly connected to the top of the mobile frame 10. A rotating gear 15 is fixedly sleeved on the output shaft of the third motor 14. A rack plate 16 meshes with the surface of the rotating gear 15. Rotary shafts 17 are rotatably connected to the front and rear sides of the mobile frame 10. Rollers 18 are fixedly connected to the surface of the rotating shafts 17.

[0030] By starting the third motor 14, the rotating gear 15 is rotated. Since the rotating gear 15 meshes with the rack plate 16, the rotating gear 15 rotates and drives the moving frame 10 to move on the crossbeam 11. At the same time, the roller 18 rotates through the rotating shaft 17 and moves in the guide rail groove 13, thereby ensuring the smoothness and stability of the movement.

[0031] There are two rotating gears 15, the rack plate 16 is located inside the mounting groove 12, and the roller 18 is adapted to the guide rail groove 13.

[0032] This utility model provides a crane anti-sway control device, the specific working principle of which is as follows:

[0033] In use, the heavy object is mounted on the hook 9 via a steel cable. The second motor 3 is started, causing the rotating rod 4 to drive the second take-up roller 5 to rotate, and the second rope 6 is taken in, thereby moving the heavy object upward. At the same time, the first motor 202 is started, causing the drive rod 203 to drive the drive wheel 204 to rotate. The belt 205 transmits power to the transmission wheel 206, and the transmission rod 207 rotates, thereby causing the transmission rod 207 and the drive rod 203 to drive the first take-up roller 208 to rotate and take in the first rope 209 to adapt to the height of the heavy object. The third motor 14 is started, causing the rotating gear 15 to rotate. Since the rotating gear 15 meshes with the rack plate 16, the rotation of the rotating gear 15 drives the moving frame 10 to move on the crossbeam 11. At the same time, the roller 18 rotates through the rotating shaft 17 and moves within the guide rail groove 13, thereby realizing the transportation of the heavy object.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
