Description

Technical Field

[0001] The utility model relates to the technical field of casting manufacturing, in particular to a lifting device for casting manufacturing. Background Art

[0002] The lifting device for casting manufacturing is a special equipment used to lift and transport castings. The use of the lifting device for casting manufacturing is to ensure that the castings are stable and reliable during transportation, avoid surface scratches and damage during transportation, protect the surface quality of the castings, and reduce the labor intensity of operators. At the same time, it reduces the risk of work-related accidents. However, castings have different shapes. Among them, tubular castings have special shapes. The use of existing lifting devices may cause damage or deformation of the castings.

[0003] At present, during the use of the existing lifting devices for casting manufacturing, due to the smooth surface of the tube-mounted casting, the lifting device may cause unstable clamping when using the clamping structure for lifting the decoration, or the center of gravity may be unstable during the clamping process, causing the tube-mounted casting to tilt or escape from the clamping during the lifting or transportation process, resulting in wear or damage and deformation of the surface of the tube-mounted casting.

The surface of the hook block is provided with anti-slip convex patterns, and the anti-slip convex patterns are made of ceramic composite materials with good high temperature resistance and high friction performance.

[0024] Reference Figure 1-5 As described, the first steel cable 2 and the second steel cable 3 are both located on the inner side of the limiting block 8. The inner side of the bottom of the limiting block 8 presents an edge rounding, which is beneficial to reducing the shaking of the first steel cable 2 and the second steel cable 3 at the bottom of the limiting block 8 when in use. The bottom of the limiting block 8 adopts such a design to reduce the friction effect on the first steel cable 2 and the second steel cable 3, which is beneficial to improving the service life of the first steel cable 2 and the second steel cable 3, and the inner bottom of the limiting block 8 near the first steel cable 2 and the second steel cable 3 presents a smooth curved surface, and a clamping groove 20 is provided on the inner side of the clamping groove 20, and a clamping rod 17 is movably sleeved on the inner side of the clamping groove 20. The outer surface of the clamping rod 17 is movably sleeved on one end of the clamping block 11, and the fixing block 15 is provided with a clamping rod 17, which can be reinforced to avoid the clamping rod 17 from falling off due to an unexpected situation during use, which is beneficial to improving the stability of casting handling when the equipment is used. The middle part of the fixing block 15 is threadedly connected with a connecting bolt 16.

[0025] Reference Figure 4-5 The spherical clamping block 18 is movably sleeved on one side of the clamping block 11 away from the fixed block 15, and the front and back of the spherical clamping block 18 are fixedly connected with a bearing ring 19. The bearing ring 19 is movably connected to the clamping block 11 at one end of the spherical clamping block 18, and the end of the spherical clamping block 18 away from the clamping block 11 is fixedly connected with a hook block 12. The surface of the hook block 12 is provided with an anti-slip convex pattern 14. High-temperature resistant high-friction material is used. Some castings may not be cooled down during transportation. The use of this material can reduce the impact of high temperature on the castings while ensuring stability. A limiting groove 21 is provided near the middle of the outer surface of the spherical clamping block 18. The limiting groove 21 is provided so that it can be conveniently clamped and fixed by the clamping rod 17. The hook block 12 is limited in a simple way, with a simple structure, low overall cost, stability and reliability. The limiting grooves 21 are evenly distributed in an array near the middle of the outer surface of the spherical clamping block 18, and the inner side of the limiting groove 21 is adapted to the clamping rod 17.

[0026] In the utility model, before use, the user needs to adjust the inclination of the hook block 12 according to the length of the casting to be lifted. The user can remove the connecting bolt 16, separate the fixing block 15, and then take out the clamping rod 17 to adjust the inclination angle of the hook block 12. The longer the tubular casting is, the more the hook block 12 tilts upward. After adjustment, the clamping rod 17 is inserted into the clamping groove 20, and the clamping groove 20 is inserted into the limiting groove 21. After the three clamping rods 17 are fixed, the fixing block 15 is fixed to the clamping rod 17, and then the fixing block 15 is fixed by the connecting bolt 16. When the height of the adjusting plate 7 is adjusted, the threaded rod 6 is driven to rotate by the servo motor 13, and then the position of the adjusting plate 7 is adjusted by the limiting effect of the limiting rod 4. The longer the tubular casting is, the higher the height of the limiting block 8 is. After adjusting to a suitable position;

[0027] When in use, the hook block 12 can be placed in the pipe openings on both sides of the tubular casting. The anti-slip convex pattern 14 can be used to increase the friction between the hook block 12 and the tubular casting, thereby improving the stability during lifting. The equipment and the casting can then be lifted and transported by lifting equipment such as a crane.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
