[0002] Machine tool castings refer to various parts (such as bed, column, slide, etc.) produced by casting process during machine tool manufacturing. Casting is a process in which molten metal is poured into a mold and cooled and solidified to form the required shape and size. These castings are usually made of materials such as cast iron, cast steel or non-ferrous metals. Machine tool castings usually serve as the main load-bearing structure of the machine tool, providing the necessary strength and rigidity to ensure the stability of the machine tool during operation.

[0003] In the existing technology, when the castings of machine tools are produced and need to be assembled, hoisting devices are generally used to assist in the assembly of the castings. However, when transporting castings by hoisting, workers need to hold the chain on the hoisting device to assist and change the direction or angle of the castings so that they can be accurately placed in the corresponding position. This increases the labor intensity of the workers and is prone to operational errors that could lead to worker injuries, resulting in low safety. Utility Model Content

[0025] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figures 1-5 As shown, this utility model provides a safe and reliable hoisting device for machine tool castings, including a hoist body 1 and a fixing plate 2. A drive motor 3 is fixedly installed on the top of the fixing plate 2, and a drive rod 4 is fixedly installed on the bottom of the drive motor 3. A drive gear 5 is fixedly installed on the outer wall of the drive rod 4, and a driven gear 6 is meshed with the outer wall of the drive gear 5. A circular groove 7 is opened at the bottom of the fixing plate 2, and two arc-shaped connecting blocks 8 are movably embedded in the inner wall of the circular groove 7. The bottom of the two arc-shaped connecting blocks 8 is fixedly connected to the top of the driven gear 6. A fixing column 9 is fixedly installed at the bottom of the fixing plate 2, and the top of the driven gear 6 is rotatably connected to the outer wall of the fixing column 9. A connecting column 10 is fixedly installed at the bottom of the driven gear 6.

[0028] The overall effect of Embodiment 1 is that when the corresponding casting is hung on the hook and needs to be transported and its orientation adjusted for assembly, the controller 25 starts the drive motor 3 installed on the fixed plate 2, which drives the drive rod 4 and the drive gear 5 to rotate. Since the drive gear 5 and the driven gear 6 are meshed, a fixed post 9 is fixedly installed at the bottom of the fixed plate 2, and the top of the driven gear 6 is rotatably connected to the fixed post 9. Furthermore, because a circular groove 7 is opened at the bottom of the fixed plate 2, and the two arc-shaped connecting blocks 8 installed on the top of the driven gear 6 are movably embedded... Within the circular groove 7, the rotation of the drive gear 5 stably drives the driven gear 6 to rotate on the fixed column 9, which in turn drives the connecting column 10, connecting plate 19, rectangular plate 20, hook body 21, and corresponding castings to rotate. The direction and position of the castings can be adjusted according to the assembly requirements between the castings, and the adjustment speed is slow, so that they can be accurately placed in the corresponding position. There is no need for the workers to hold the chain 11 on the hoisting device to assist in changing the direction or angle of the castings, which reduces the labor intensity of the workers and improves the safety of operation.

[0029] Example 2: As Figures 2-5As shown, two chains 11 are provided on one side of the outer wall of the hanger body 1, and the bottom of both chains 11 is fixedly connected to the top of the fixing plate 2. A forward and reverse motor 12 is fixedly installed on the top of the hanger body 1. A threaded rod 13 is fixedly installed on one side of the outer wall of the forward and reverse motor 12, and the outer wall of the threaded rod 13 is movably inserted into the interior of the hanger body 1. A movable column 14 is threadedly connected to the outer wall of the threaded rod 13, and the outer walls of both chains 11 are fixedly connected to the opposite side of the outer wall of the movable column 14. A strip groove 15 is opened on the top of the hanger body 1, and a strip slider 16 is movably embedded in the inner wall of the strip groove 15. The top of the strip slider 16 is fixedly connected to the bottom of the movable column 14. A protective cover 17 is fixedly installed on the top of the hanger body 1. Multiple heat dissipation holes 18 are provided on one side of the outer wall of the cover 17. A connecting plate 19 is fixedly installed at the bottom of the connecting column 10. A rectangular plate 20 is in contact with the bottom of the connecting plate 19. A hook body 21 is fixedly installed at the bottom of the rectangular plate 20. Four positioning blocks 22 are fixedly installed at the top of the rectangular plate 20. Four positioning holes 23 are provided at the top of the connecting plate 19. The outer walls of the four positioning blocks 22 are movably inserted into the four positioning holes 23. Bolts 24 are threadedly connected to one side of the outer wall of the four positioning blocks 22. The outer walls of the four bolts 24 are movably inserted into the connecting plate 19. A controller 25 is fixedly installed on one side of the outer wall of the hanger body 1. The outer wall of the controller 25 is electrically connected to the outer walls of the drive motor 3 and the forward and reverse motor 12.

[0030] The overall effect of Embodiment 2 is that when the hoisting device is transporting and transferring castings, the forward and reverse motors 12 are activated by the controller 25. Since the strip-shaped slider 16 installed at the bottom of the moving column 14 is movably embedded in the strip-shaped groove 15 opened at the top of the hanger body 1, the moving column 14 can move stably on the threaded rod 13. Because two chains 11 are installed on the hanger body 1, and the two ends of the two chains 11 are respectively fixedly connected to the top of the fixed plate 2 and one side of the outer wall of the moving column 14, the two chains 11, the fixed plate 2, and the corresponding castings can be moved up and down, thereby satisfying the lifting and lowering of the castings. This improves the flexibility of transportation operations. Secondly, four positioning blocks 22 are fixedly installed on the top of the rectangular plate 20, and the four positioning blocks 22 are precisely inserted into the four positioning holes 23 opened on the top of the connecting plate 19, which has a positioning effect. Then, through the action of four bolts 24, they pass through the connecting plate 19 and are threaded into the four positioning blocks 22, thereby installing the rectangular plate 20 and the hook body 21 under the connecting plate 19. The disassembly and assembly process is simple, so that the corresponding hooks, lifting rings or internal support lifting devices can be installed according to the needs of hoisting and handling machine tool castings, which improves the flexibility and reliability of transporting machine tool castings on site.

[0031] Working principle: First, select a suitable hook body 21 according to the type of machine tool castings to be transported and assembled. Then, the rectangular plate 20 and four positioning blocks 22 installed on its top are inserted into the positioning holes 23 opened on the top of the connecting plate 19, which has a positioning effect. Next, the rectangular plate 20 and the hook body 21 are installed under the connecting plate 19 by four bolts 24. Then, the castings are transferred and the corresponding assembly is completed by the lifting device and the hook body 21. The forward and reverse motors 12 are started by the controller 25, which drive the threaded rod 13 to rotate inside the lifting frame body 1. Since the strip slider 16 installed at the bottom of the moving column 14 is movably embedded in the strip groove 15, the moving column 14 moves stably on the threaded rod 13, and drives the two chains 11, the fixed plate 2 and the corresponding castings to move up and down, thereby meeting the needs of the site. Regarding the flexibility of transporting castings, when it is necessary to adjust the assembly direction or angle of the castings, the controller 25 starts the drive motor 3, which drives the drive rod 4 and the drive gear 5 to rotate. Since the two arc-shaped connecting blocks 8 installed on the top of the driven gear 6 are movably embedded in the circular groove 7, and the driven gear 6 is meshed with the drive gear 5, the rotation of the drive gear 5 can drive the driven gear 6 to rotate stably on the fixed column 9, and drive the connecting column 10, connecting plate 19, rectangular plate 20, hook body 21 and the corresponding castings to rotate. It can also be adjusted to a suitable angle and direction as needed, so that it can be accurately placed in the corresponding position, reducing the fatigue of the workers and eliminating the need for the workers to hold the parts with their hands to complete the operation, thus improving the operational safety and improving the effectiveness of the machine tool casting lifting device.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
