[0002] A lifting frame is a device used for lifting and moving heavy objects, usually composed of one or more pillars and beams. The history of the lifting frame can be traced back to ancient times when people used ropes and wooden structures to carry out moving work. With the development of industrialization and modernization, the lifting frame has gradually evolved into various forms and is widely used in various places. It can help people complete lifting and moving work efficiently. Its development and application have promoted the development and progress of industrial production.

[0003] However, when a general lifting frame lifts a heavy object through a sling, it is inevitable that it will shake, which will affect the stability of the lifting frame and the safety of the lifting process, and may also cause damage to the lifted object. On the other hand, the lifting frame usually requires a large amount of space for installation and operation, which will limit the use of the lifting frame in a small or crowded workplace and make it difficult to adjust its position.

The top wall of the anti-sway platform 13 is fixedly connected with U-shaped bars 11 on both sides, and the bottom outer wall of the U-shaped bar 11 passes through the bottom wall of the slide plate 6 and is fixedly connected with the hook 5. A lifting motor 10 is installed in the middle of the top wall of the lifting platform 20, and the output end of the lifting motor 10 is fixedly connected with the sling 9, and the other end of the sling 9 passes through the top wall of the lifting platform 20 and is fixedly connected with a stabilizing block 16. The side wall of the stabilizing block 16 is fixedly connected to the middle of the anti-sway platform 13, and the bottom wall of the stabilizing block 16 is fixedly connected with the hook 5. A moving component is provided at the bottom of the hanger body 2.

[0033] Specifically, the lead screw 7, the transmission bevel gear 14, and the rotating bevel gear 15 are all rotatably connected to the inside of the lifting platform 20, and the anti-sway platform 13 is fixedly connected to the side wall of the stabilizing block 16 used to connect the sling 9 and the hook 5. The anti-sway platform 13 is slidably connected to the slide plate 6 through the U-shaped bar 11. The slide plate 6 can move up and down synchronously with the rise and fall of the sling 9 on the side wall of the hanger body 2 through the protrusion 12 on its side wall, thereby effectively avoiding the shaking of the hook 5 during the lifting process. At the same time, multiple hooks 5 are auxiliaryly arranged on the bottom wall of the U-shaped bar 11 to enhance the stability of the lifted object.

[0034] The mobile component includes a base 1. The two sides of the top outer wall of the base 1 are fixed to the bottom outer wall of the hanger body 2. The bottom of the side wall of the hanger body 2 is fixedly connected with a fixing plate 4. The middle of the bottom wall of the fixing plate 4 is installed with a cylinder 3. The output end of the cylinder 3 passes through the top wall of the base 1 and is fixedly connected with a connecting plate 17. Both sides of the bottom wall of the connecting plate 17 are fixedly connected with universal wheels 18. A sliding groove 19 is opened on the bottom outer wall of the base 1. The connecting plate 17 and the universal wheel 18 are both slidably connected in the sliding groove 19.

[0035] Specifically, the lead screw 7 at the top of the hanger body 2 can complete the extension and retraction of the hanger bodies 2 on both sides under the action of the retraction motor 8, thereby increasing the flexibility of the lifting frame. At the same time, a concealable universal wheel 18 is arranged on the base 1 through the cylinder 3 and the slide groove 19, which facilitates the movement of the lifting frame.

[0037] Working principle: First, according to the area restrictions of the workplace, the cylinder 3 works to push out the universal wheel 18 in the base 1, and then the contraction motor 8 drives the hanger body 2 and the slide plate 6 to extend and contract, so as to achieve fine-tuning of the position of the lifting frame. After the position is fixed, the hook 5 and the sling 9 descend under the action of the stabilizing block 16 and their own weight. After the lifting object is fixed, the lifting motor 10 is started, and the hook 5 and the sling 9 rise synchronously to complete the lifting. At the same time, during the lifting process, the slide plate 6 and the anti-sway platform 13 move up and down synchronously to ensure that the hook 5 will not produce unnecessary shaking.
