[0002] A crane is a mechanical device used to lift and transport goods. Its working principle is based on mechanical, hydraulic or electrodynamic principles. A crane is usually composed of a hook, a lifting arm, a support structure, a power system and a control system. Different types of cranes can be selected according to different work scenarios and needs. Its main function is to move goods from one location to another and ensure safe and efficient operations.

[0003] Existing small cranes usually grab and lift the goods, move them to a designated position through bottom rollers and release them to achieve the purpose of transporting the goods.

[0004] However, due to the heavy weight of the cargo, the inertia of the cargo may cause shaking between the hook and the cable, thereby increasing the pressure on the cable. When grasping heavy cargo, the cable may be severely damaged, and the connection between the cargo and the hook may also become loose or broken. Utility Model Content

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.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, a stable conveying crane comprises a frame 1. The frame 1 is connected to a hanger 2. A pay-off wheel 3 is arranged on one side of the hanger 2. A cable 4 is wound inside the pay-off wheel 3. A driving motor 5 is connected to one side of the pay-off wheel 3 for paying out or taking up the line. A driving cylinder 6 for driving the hanger 2 to rotate is also arranged on one side of the frame 1. A slide bar 7 is slidably connected to one side of the hanger 2. A lifting ring 8 is arranged at the end of the slide bar 7. A lifting hook 9 is connected to the lifting ring 8. Among them, the lifting ring 8 is connected to the cable 4, and the cable 4 is connected to the pay-off wheel 3. A corresponding roller can also be arranged in the middle to facilitate the movement of the cable 4. This is a prior art, so it is not repeated.

[0023] The core technical solution of this application is as follows:

[0024] A fixing seat 10 is provided on one side of the hanger 2. A slide groove 11 is provided on one side of the fixing seat 10. A fixing frame is slidably connected in the slide groove 11. The fixing frame is divided into two semicircular frames 12. A notch 13 is provided inside the semicircular frame 12, and the shape of the notch 13 matches the shape of the lifting ring 8 and the extended cable 4 or is larger than the diameter of the lifting ring 8 and the cable 4. When the semicircular frames 12 move toward each other to correspond to the lifting ring 8 and the cable 4, the hook 9 is stable, and it is not easy to cause the cable 4 to swing due to the shaking of the goods during the movement of the frame 1, so as to achieve the purpose of stable transportation.

[0025] As mentioned above, a fixing block 14 is connected to one side of the semicircular frame 12. A rotating shaft 15 is hinged on the fixing block 14. A waist-shaped rod 16 is hinged on the rotating shaft 15. The ends of the two waist-shaped rods 16 close to each other are commonly connected to a sliding seat 17. The sliding seat 17 is connected to an output shaft 18. The output shaft 18 is connected to an output cylinder 19. Among them, one end of the output shaft 18 is connected to the sliding rod 7. As mentioned above, when the cylinder is working, it can drive the sliding rod 7 to move back and forth on the hanger 2, thereby driving the hook 9 to move back and forth, and then adjusting the position of the hook 9.

[0026] Overall working process:

[0027] 1. In the initial state, the slide rod 7 is driven by the cylinder to move outward. During this process, the output shaft 18 extends outward, driving the sliding seat 17 to move;

[0028] 2. When the sliding seat 17 moves outward, it drives the waist-shaped rod 16 to swing, so that the semicircular frame 12 moves in the opposite direction and moves away from each other to reach the position as shown in FIG. Figure 1 The position shown is the maximum distance;

[0029] 3. After the cargo is suspended by the pay-off wheel 3, the cylinder works to drive the slide bar 7 to reset. During this process, the waist-shaped rod 16 swings, driving the two semicircular frames 12 to move toward each other, so that the two semicircular frames 12 gradually approach the middle. When the output shaft 18 drives the sliding seat 17 to reset to the cylinder position, the two semicircular frames 12 abut and overlap. At this time, the hook 9 also reaches the position of the semicircular frame 12, so that the eyelet 8 and the cable 4 are covered by the two semicircular frames 12, achieving a fixing effect;

[0030] 4. Move the frame 1 to output the goods to the designated location. During the movement, since the swing or shaking of the cable 4 is limited by the two semicircular frames 12, no violent swing will occur, thus achieving the purpose of stable transportation.

[0031] 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, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
