Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Reference Figures 1 to 2The utility model provides an embodiment of an automatic lifting device for hot-dip galvanizing and pickling, comprising a plurality of support legs 1, a basic supporting structure of the support leg 1 device, the design of the support leg 1 taking into account stability and balance to support the weight of the entire lifting device and the load of the lifted object, a plurality of support legs 1 are provided with a T-shaped slide 2 on the adjacent side, these slides are located on the adjacent side of the support leg 1, and are used to slide and connect other components to ensure that the device moves up and down smoothly during the lifting process, a plurality of T-shaped slides 2 are slidably connected to the inside of each of the T-shaped slides 10, and the T-shaped slide 10 can prevent it from deviating from the track when moving up and down, a plurality of T-shaped slides 10 are fixedly connected to the adjacent side of the two limit plates 11, and a T-shaped slide 2 12 is provided inside the two limit plates 11, and the limit plates 11 can provide horizontal limitation for the lifted object to reduce horizontal shaking, a plurality of support legs 1 are fixedly connected to the adjacent side of the two electric slide rails 3, and the electric slide rails 3 can transport the lifted workpiece to the pickling area. The top of the two electric slides 3 are slidably connected to the slide 4, and the top of the slide 4 provides a driving component to provide a power source for lifting and lowering the workpiece. The top of the slide 4 is fixedly connected to a double-headed motor 5, which can provide a synchronous power source in two directions. The bottom of the slide 4 is fixedly connected to two fixed frames 6, which are used to support the subsequent structure and make it operate. The internal rotation of the fixed frame 6 is connected to a winch 7, which is used to store and release subsequent components. The outside of the winch 7 is wrapped with a lifting rope 8, which can lift and lower the workpiece by winding and releasing. The bottom of the lifting rope 8 is fixedly connected to a fixing part 14, and a disassembly component is set inside the fixing part 14 for disassembling the components of the subsequent structure. The outside of the two lifting ropes 8 is fixedly connected to a connecting plate 9, which connects the two lifting ropes 8 together to reduce the possibility of shaking. The left and right sides of the bottom of the connecting plate 9 are fixedly connected to T-shaped sliders 13, which limit the horizontal movement of the workpiece to reduce shaking.
[0032] Reference Figure 1 The two driving ends of the double-headed motor 5 rotate respectively inside the two fixing frames 6, and the two driving ends of the double-headed motor 5 are respectively installed inside the two fixing frames 6. This arrangement enables the double-headed motor 5 to be firmly fixed on the main structure of the lifting device, thereby effectively rotating and controlling the movement of each component. The two driving ends of the double-headed motor 5 are externally fixedly connected to the inside of the two winches 7, and the winches 7 are driven by the double-headed motor 5 to rotate, thereby realizing the control of the lifting rope 8. The external sliding connection of multiple T-shaped sliders 10 is inside the T-shaped slide 12, and the external sliding connection of two T-shaped sliders 2 13 is inside the T-shaped slide 2 12. Through the sliding limit of T-shaped slider 10 and T-shaped slider 2 13, the shaking of the hook 16 and the workpiece is reduced, the safety hazard is reduced, and the safety is improved.
[0033] Reference Figures 3 and 4 The disassembly component includes two sleeves 15, the outer sides of the two sleeves 15 are slidably connected to the inside of the two fixing parts 14, and the two sleeves 15 are slidably connected to the inside of the fixing parts 14 and the hook 16. The fixing parts 14 and the hook 16 are connected together by snapping. The internal thread of the sleeve 15 is connected with a screw 17. The screw 17 can provide a unidirectional rotation force to drive the subsequent components to rotate unidirectionally. The far side of the two screws 17 is fixedly connected with a handle 18. These handles 18 are used to manually rotate the screws 17, thereby controlling the movement and position adjustment of the sleeve 15, which is convenient for disassembly and replacement and maintenance of components. The close side of the two sleeves 15 is fixedly connected with a connecting shell 19. The sliding component is accommodated inside the connecting shell 19 to facilitate sliding out of the limit. The internal rotation connection of the connecting shell 19 There is a rotating plate 21, and a plurality of arc grooves 22 are opened inside the rotating plate 21. Through the rotation of the rotating plate 21 and the arc groove 22, the subsequent structure is driven to extend and engage, and the interiors of the two connecting shells 19 are respectively provided with a plurality of sliding grooves 20. The interiors of the plurality of sliding grooves 20 are slidably connected with baffles 23, and the extension and engagement are achieved through the sliding of the baffles 23. The far sides of the plurality of baffles 23 are fixedly connected with protrusions 24. The protrusions 24 are structures connecting the arc grooves 22 and the baffles 23. The direction of the force is changed by the arc grooves 22. The near sides of the two screws 17 are respectively fixedly connected to the far sides of the two connecting shells 19. Such a design can drive the rotating plate 21 to rotate by the rotation of the screws 17, and the outsides of the plurality of protrusions 24 are in contact with the insides of the plurality of arc grooves 22.
[0034] Working principle: First, by turning on the switch of the double-headed motor 5, the driving ends at both ends drive the two winches 7 to rotate, loosen the lifting rope 8 on the winch 7, and lower the two hooks 16 to hook the sorted workpiece. Through the reverse switch of the double-headed motor 5, the lifting rope 8 is driven to rise, and the rise of the lifting rope 8 drives the limit plate 11 and the T-shaped slider 10 at both ends to slide inside the support leg 1, and then the sliding of the slide plate 4 drives the entire lifting device to slide on the top of the electric slide rail 3. At the same time, the connecting plate 9 and the bottom T-shaped slider 13 are driven to slide inside the limit plate 11, providing sliding limit for the workpiece hooked by the hook 16 to prevent shaking, and finally they are placed in the pickling tank for pickling, reducing instability and the possibility of accidents during the lifting process. The device can stabilize the position of the object and prevent it from swinging or shaking in the air, thereby reducing the risk of accidents and protecting the safety of workers and equipment.
[0035] Secondly, since the hook 16 at the bottom hooks the workpiece, it is usually corroded by acid. When a new hook 16 needs to be replaced, the screw 17 is driven inside the sleeve 15 by rotating the handle 18, driving the internal rotating plate 21 to rotate, thereby driving the protrusion 24 to move relative to each other along the arc groove 22, and then driving the baffle 23 to shrink inside the connecting shell 19, and then pulling the entire sleeve 15 to slide inside the fixing part 14 and the hook 16, and then sliding the hook 16 to complete the separation of the hook 16 from the fixing part 14. At this time, slide the new hook 16 to the inside of the fixing part 14, and then slide the sleeve 15 to the middle of them, and drive the screw 17 and the rotating plate 21 to rotate by rotating the handle 18, driving the baffle 23 to extend out of the connecting shell 19 to complete the engagement and fix the new hook 16. Through the fixing frame 6 that is easy to disassemble and replace, the disassembly and replacement of the hook 16 makes the maintenance of the lifting equipment more convenient and increases the service life of the lifting equipment.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
