Description

Technical Field

[0001] The invention relates to the technical field of cable lifting devices for galvanizing processing, and in particular to a lifting device and method for galvanizing processing of steel components based on high efficiency, strong adhesion and uniformity. Background Art

[0002] Steel components are important materials that are indispensable for national construction and the realization of the four modernizations. They are widely used and come in a wide variety. In order to improve their corrosion resistance and extend their service life, especially in outdoor and harsh environmental conditions, such as the seaside, industrial areas and high-humidity areas, steel components are usually galvanized. During the galvanizing process, it is necessary to use lifting equipment to lift the steel components into the zinc pot and then fish them out. Subsequently, in order to improve the uniformity of the zinc layer, an air nozzle is used to blow away the excess zinc liquid on the surface of the steel components. At present, when blowing away the zinc liquid, the steel components are generally suspended in mid-air for operation. During the process, because the steel components are in a horizontal state, the zinc liquid will fan out under the blowing of the airflow, and the convergence effect is general, resulting in a long time required for the blowing process, which reduces the overall efficiency of the galvanizing process;

[0003] For example, the large-span steel structure frame construction auxiliary lifting equipment for venue construction disclosed by announcement number CN118405591A can effectively absorb steel components, but in the process of zinc removal, the zinc liquid will spread in a fan shape under the blowing of airflow, and the convergence effect is general. A lifting equipment for steel structure disclosed by announcement number CN217867827U can automatically clamp steel components, but in the process of air blowing zinc removal, the steel components can only remain horizontal, and there is still the problem that the zinc liquid will spread in a fan shape under the blowing of airflow, and the convergence effect generally leads to a decrease in the overall efficiency of the galvanizing process. Therefore, a lifting device and method for high-efficiency, strong adhesion and uniform galvanizing of steel components are proposed. Summary of the invention

[0024] The present invention provides a lifting device and method for high-efficiency, strong-adhesion and uniform galvanizing of steel components. Compared with the prior art, it has the following beneficial effects:

[0025] (1) The lifting device and method for high-efficiency, strong adhesion and uniform galvanizing of steel components are provided by arranging a crane group, a lifting hook, a hydraulic cylinder, a support plate, a limit rod, a steel wire, a main board, a support plate, a hook, a power motor, a rotating shaft, a power gear, a driven gear, a movable shaft, a limit block, a limit plate, a transmission gear, a sliding shaft, a flip gear, a guide rod, a guide plate, an inner magnet, a limit sleeve, a support rod, an outer magnet and a connecting rod. The steel component to be galvanized is hung on the hook, and then the crane group is controlled to drive the steel component to move into the zinc pot through the lifting hook for galvanizing. Then, the crane group is controlled to operate to transfer the galvanized steel component to the de-galvanizing process. The surface of the steel component is blown by an air nozzle to help remove excess zinc liquid on the surface of the steel component, which also helps to make the zinc layer flat and uniform. During the de-galvanizing process, one of the hydraulic cylinders on both sides of the lifting hook is controlled to start. The hydraulic cylinder drives the support plate on that side to move, so that the main board and the support plate are tilted after the steel wire moves downward, so that during the blowing process of the air nozzle, the excess zinc liquid on the surface of the steel component can be accelerated to flow to the lower end, shortening the operation time required for the zinc removal process and improving the production efficiency of the galvanizing of the steel component; after the main board and the support plate are tilted, the power motor is controlled to start, so that the support plate drives the steel component to rotate through the hook, and at the same time, after the steel component rotates to a set angle, the power motor can be automatically controlled to rotate in the opposite direction, so that the steel component on the hook can be tilted and then rotated back and forth with the limit sleeve as the axis, so as to facilitate blowing from different angles, improve the effect of zinc liquid removal, and the degree of tilt is adapted to the progress of the air nozzle blowing, gradually increasing the tilt angle, further accelerating the separation of excess zinc liquid on the surface of the steel component, and making the traces produced by the flow of zinc liquid during the separation process lighter, so that the galvanized layer of the steel component is more uniform.

[0026] (2) The lifting device and method for high-efficiency, strong-adhesion and uniform galvanizing of steel components are provided with a hydraulic oil tank, a piston, a fixed plate, an electric telescopic rod, an elastic bag, a sliding plate and a sliding shaft. The limit sleeve is no longer directly installed on the main board, but is installed on the sliding plate. The sliding plate is slidably inserted into the main board. By controlling the start of the electric telescopic rod, the sliding plate is extended from the main board, thereby driving the support plates on both sides of the main board to extend synchronously, and can be retracted into the main board again with the operation of the electric telescopic rod, so that the spacing between the hooks can be changed, so that steel components of different sizes can be lifted for galvanizing processing, thereby increasing the scope of application of the equipment, eliminating the need for frequent replacement of lifting tools, improving the flexibility of operation, and reducing the number and cost of equipment.

[0027] (3) The lifting device and method for high-efficiency, strong-adhesion and uniform galvanizing of steel components are provided with a hook ring, a guide plate, a slider, a baffle, a spring and a guide block. A hook with a lock is not used. The main board provides support for the hook ring and the guide plate. When the support plate is turned over by the limit sleeve as the axis under the drive of the power motor and turns over to the side of the hook opening, the opening of the hook is blocked by the automatically extended baffle to prevent the steel component from falling from the opening of the hook during the turning process. After the degalvanizing operation is completed, the hook ring is hooked with the help of a rod to turn over the main board to detach the processed steel component from the hook. There is no need to directly touch the locked hook to perform the unlocking operation to avoid burns. At the same time, the steel component will not fall from the hook during the turning and blowing degalvanizing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] One end of the connecting rod 313 is fixedly mounted on the support plate 25 to provide support force to the support plate 25 .

[0046] When in use, the steel member to be galvanized is hung on the hook 26, and then the crane group 1 is controlled to drive the main board 24 to move through the lifting hook 11, and the main board 24 drives the support plate 25 to move, so that the support plate 25 can drive the steel member to move to the zinc pot through the hook 26 for galvanizing. Then, the crane group 1 is controlled to operate, and the galvanized steel member is transferred to the dezincification process, and the surface of the steel member is blown through the air nozzle to help remove excess zinc liquid on the surface of the steel member, and it also helps to make the zinc layer flat and uniform. During the process, one of the hydraulic cylinders 2 on both sides of the lifting hook 11 is controlled to start, so that the hydraulic cylinder 2 drives the support plate 21 on the side to move, and the support plate 21 on the side drives the limit rod 22 on the side to move, and the limit rod 22 drives the steel wire 23 to move, so that the main board 24 and the support plate 25 are tilted after the steel wire 23 on one side moves down, so that during the blowing process of the air nozzle, the excess zinc liquid on the surface of the steel component can be accelerated to flow to the lower end, shortening the operation time required for the zinc removal process, and improving the production efficiency of the galvanizing process of the steel component;

[0047] After the main board 24 and the support board 25 are tilted, the power motor 3 is controlled to start, the power motor 3 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the power gear 32 to rotate, the power gear 32 drives the driven gear 33 to rotate, the driven gear 33 drives the movable shaft 34 to rotate, and the movable shaft 34 drives the transmission gear 35 and the limit block 341 to rotate synchronously;

[0048] The transmission gear 35 drives the flip gear 36 to rotate, and the flip gear 36 drives the inner magnet 39 to rotate, and the inner magnet 39 drives the guide rod 37 to rotate. The guide rod 37 and the guide plate 38 are slidably matched, so that the guide plate 38 guides and limits the guide rod 37, and the main board 24 provides a supporting force for the guide plate 38, and the guide plate 38 provides a supporting force for the limiting sleeve 310, and the limiting sleeve 310 provides a supporting force for the support rod 311. The support rod 311 and the transmission gear 35 are movably connected through a bearing, and the limiting sleeve 310 provides a supporting force for the outer magnet 312, and the outer magnet 312 provides a supporting force for the connecting rod 313. The connecting rod 313 is connected to the support plate 25, and the outer magnet 312 and the inner magnet 39 are magnetically attracted to each other, so that the inner magnet 39 drives the outer magnet 312 to rotate synchronously, so that the outer magnet 312 drives the support plate 25 to rotate through the connecting rod 313, and the support plate 25 drives the steel component to rotate through the hook 26;

[0049] When the movable shaft 34 rotates, it drives the limit block 341 to rotate synchronously. When the limit block 341 and the limit plate 342 abut against each other, the pressure strain gauge installed on the side close to each other senses a value, and a control signal is transmitted to make the power motor 3 rotate in the opposite direction until the limit block 341 and the limit plate 342 on the other side abut against each other again, and the power motor 3 rotates in the opposite direction again, so that the steel component on the hook 26 can be tilted and then rotated back and forth with the limit sleeve 310 as the axis, and the tilting degree is adapted to the progress of the air nozzle blowing, and the tilting angle is gradually increased, so as to further accelerate the separation of excess zinc liquid on the surface of the steel component, and make the traces of the flow of zinc liquid lighter during the separation process, so that the zinc coating of the steel component is more uniform;

[0050] After the excess zinc liquid on the surface of the steel component is removed, the hydraulic cylinder 2 is controlled to reset to Figure 2 At the same time, the power motor 3 also drives the rotating shaft 31 to reset to Figure 2 After the state shown, the crane group 1 is controlled to transfer the steel component after removing the excess zinc liquid to the next process.

[0051] Embodiment 2, the technical solution of this embodiment is different from that of embodiment 1, including: an adjustment component for adjusting the lifting size is provided on the lifting hook 11, and the adjustment component includes: a hydraulic oil tank 4, a piston 41, a fixing plate 42, an electric telescopic rod 43, an elastic bag 44, a sliding plate 45, a sliding shaft 351, and a support rod 311;

[0052] The bottom of the hydraulic oil tank 4 is fixedly mounted on the top of the main board 24, a piston 41 is slidably mounted in the hydraulic oil tank 4, the top of the piston 41 is fixedly mounted on the bottom of the fixed plate 42 through a mounting rod, an electric telescopic rod 43 is fixedly mounted on the bottom of the fixed plate 42, and the bottom of the electric telescopic rod 43 is fixedly mounted on the top of the main board 24;

[0053] The hydraulic oil tank 4 is connected to two elastic bags 44 through two oil pipes. One end of the two elastic bags 44 is fixedly mounted on both sides of the main board 24. The other ends of the two elastic bags 44 are magnetically connected to a sliding plate 45 through magnets. One end of the two sliding plates 45 is slidably inserted into the main board 24. The other ends of the two sliding plates 45 are fixedly mounted with a guide plate 38.

[0054] The transmission gear 35 is no longer directly installed on the movable shaft 34. A support rod 311 is fixedly installed on the top of the limit sleeve 310. One end of the support rod 311 is movably installed on the side wall of the transmission gear 35 through a bearing. A sliding shaft 351 is fixedly installed on the side wall of the transmission gear 35. One end of the sliding shaft 351 is slidably inserted into the movable shaft 34.

[0055] When in use, the guide plate 38 is no longer directly mounted on the main board 24, but is mounted on the sliding plate 45. The sliding plate 45 is slidably inserted into the main board 24, and the sliding shaft 351 is slidably inserted into the movable shaft 34. By controlling the electric telescopic rod 43 to start, the electric telescopic rod 43 drives the fixed plate 42 to move, the fixed plate 42 drives the piston 41 to move, and the piston 41 drives the hydraulic oil in the hydraulic oil tank 4 to flow into the elastic bag 44 through the oil pipe, so that the elastic bag 44 expands, and the expanded elastic bag 44 squeezes the sliding plate 45 to move , so that the sliding plate 45 extends from the main board 24, thereby driving the support plates 25 on both sides of the main board 24 to extend synchronously. At the same time, as the support plates 25 extend, the limiting sleeve 310 will be synchronously driven to move to the side away from the main board 24. The limiting sleeve 310 drives the transmission gear 35 to move synchronously through the support rod 311, so that the transmission gear 35 and the flip gear 36 are always in a meshing state. The elastic bag 44 and the sliding plate 45 on the same side are connected by two magnets, so that the electric telescopic rod 43 drives the fixed plate 42 and the piston 41 to move. Fig.10 After the position shown is reset, when the hydraulic oil in the elastic bag 44 is sucked back into the hydraulic oil tank 4, the sliding plate 45 is retracted into the main board 24 by the magnetic attraction force, so that the distance between the hooks 26 can be changed, so that steel components of different sizes can be lifted for galvanizing processing, thereby increasing the application range of the equipment.

[0056] Embodiment 3, the technical scheme that distinguishes this embodiment from Embodiment 2 includes: a safety component for improving operation safety is arranged on the lifting hook 11, and the safety component includes: a hook ring 5, a guide plate 51, a slider 52, a baffle 53, a spring 54, and a guide block 55. A hook ring 5 is fixedly installed on the side wall of the main board 24, two symmetrically arranged guide plates 51 are fixedly installed on the side wall of the main board 24, two symmetrically arranged baffles 53 are slidably passed through the support plate 25, a slider 52 is fixedly installed on the top of the two baffles 53, and the top of the slider 52 is provided with an inclined surface, a spring 54 is fixedly installed on the side wall of the two baffles 53, and the bottom of the spring 54 is fixedly installed on the top of the main board 24, a guide block 55 is slidably passed through the two baffles 53, and one end of the two guide blocks 55 is fixedly installed on the top of the main board 24.

[0057] When in use, the hook 26 with lock is not used, and the main board 24 provides supporting force for the hook ring 5 and the guide plate 51. When the support plate 25 is turned over with the limit sleeve 310 as the axis under the drive of the power motor 3, when it turns over to the side of the opening of the hook 26, the guide plate 51 will slide and abut against the slider 52, so that the slider 52 drives the baffle plate 53 to move downward under the squeezing of the guide plate 51, and the baffle plate 53 and the guide block 55 are slidably matched, so that the guide block 55 only moves in a straight line during the movement, and the opening of the hook 26 is blocked by the extended baffle plate 53 to prevent the steel component from falling from the opening of the hook 26 during the turning process. When turning over to the opposite direction of the opening of the hook 26, the slider 52 will not abut against the guide plate 51, and the baffle plate 53 is kept in the position under the action of the spring 54. Figure 1 The hook 26 flipped in this direction will not be affected by the guide plate 51. After the zinc removal operation is completed, the processed steel component can be detached from the hook 26 by hooking the hook ring 5 with a rod and flipping the main board 24.

[0058] In another embodiment different from the aforementioned embodiment, the guide plate 51 is replaced with a telescopic type, and the outer guide plate 51 is fixedly connected to the limit sleeve 310 through a fixed column, so that the guide plate 51 after adjusting the spacing of the hooks 26 can still slide and abut against the slider 52, so that the baffle 53 extends downward to block the opening of the hook 26.

[0059] The embodiment of the present invention also provides a dezincification method suitable for a hoisting device for high-efficiency, strong-adhesion and uniform galvanizing of steel components, comprising the following steps:

[0060] S1, using the adjustment component to adjust the spacing of the hooks 26 to the desired distance;
