Description

Technical Field

[0001] This invention relates to the field of hot-dip galvanizing lifting equipment, and more specifically, to a lifting equipment for hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing is a common metal surface anti-corrosion treatment process. It involves immersing metal workpieces such as steel pipes and profiles in molten zinc, forming a zinc layer on the workpiece surface to improve its corrosion resistance. During the hot-dip galvanizing process, lifting equipment is typically used to clamp, transport, and immerse the pipes in and out of the galvanizing bath to ensure they enter the galvanizing bath stably and complete the galvanizing process.

[0003] Existing lifting devices for hot-dip galvanizing pipe fittings typically employ hooks, grippers, or support rods for hoisting and transporting the fittings. While these structures meet basic lifting requirements, several problems remain in practical applications: First, the clamping and securing of fittings often requires manual assistance, reducing the continuity and efficiency of the hot-dip galvanizing operation. Second, adjusting the fitting's position when immersed in the galvanizing bath usually requires the coordinated use of two lifting devices, making the operation cumbersome and difficult to control. Furthermore, after prolonged use, oxide slag and other impurities tend to float on the zinc bath surface, adhering to the fitting surface upon removal and affecting galvanizing quality. Current methods rely heavily on manual scraping to remove the slag, which is not only labor-intensive but also generates exhaust fumes that adversely affect worker health.

[0004] In view of this, a lifting tool for hot-dip galvanizing is proposed. Summary of the Invention

The guide frames are slidably connected to the connecting pipes, and the connecting pipes are fixed to the support frames. The support frames are fixed to a plurality of support columns distributed at equal intervals. There are two fixed frames, which are respectively fixed to the two guide members. Each fixed frame is fixed to a guide rail, and the guide rail is slidably connected to a slider. The slider is fixed to a fixed rod, which is located inside the connecting tube and the two are slidably connected. A sprocket is rotatably connected to the connecting frame. A motor is fixedly connected to the connecting frame. The output shaft of the motor is fixedly connected to the sprocket. A fixed frame is rotatably connected to the sprocket. A chain is connected between the sprocket and the sprocket. The chain is fixedly connected to the slider.

[0007] Furthermore, the guide rail is rotatably connected to a threaded rod, which passes through the slider and the two are threadedly connected. The guide rail is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the threaded rod.

[0008] Furthermore, it also includes a cleaning mechanism disposed between the two guide members, the cleaning mechanism comprising: There are two guide rails, which are respectively fixed to two guide members. Two sliders are slidably connected to the guide rails. An elastic member is fixed between the sliders and the guide rails. A support shaft is rotatably connected between the two sliders on both sides. There are two cleaning plates, which are respectively fixed to the two support shafts.

[0009] Furthermore, the two cleaning plates are arranged in a figure-eight pattern.

[0010] Furthermore, the support shaft is fixedly connected to a gear and a ratchet, and a torsion spring is fixedly connected between the slider and the ratchet.

[0011] Furthermore, two fixed seats are fixedly connected to the upper side of the second guide rail. A sliding frame is slidably connected to the fixed seat. A rack is fixedly connected to the sliding frame. The rack meshes with the adjacent gear. A spring is fixedly connected between the sliding frame and the fixed seat.

[0012] Furthermore, the slider three is fixedly connected to a guide shell, the guide shell is slidably connected to a connecting block, and the lower side of the guide rail two is fixedly connected to two fixing plates, the fixing plates are provided with guide grooves, and the connecting block is located in the guide grooves.

[0013] Furthermore, the guide groove includes a central horizontal section and downwardly inclined sections connected to both ends of the central horizontal section.

[0014] Furthermore, the connecting block is fixedly connected to a fixed sleeve, the fixed sleeve is slidably connected to a pawl, the pawl limits the ratchet, and an elastic element is fixedly connected between the pawl and the fixed sleeve.

[0015] Furthermore, the second guide rail is fixedly connected to two guide wheels, and electric winding wheels are fixedly connected to both sides of the guide member. A steel wire rope is fixedly connected between the electric winding wheel and the third slider, and the steel wire rope is wound around the outside of the guide wheel.

[0016] Compared with the prior art, the present invention provides a lifting device for hot-dip galvanizing, which has the following beneficial effects: 1. This invention, through the cooperation of motor one, threaded rod, slider two, fixed rod, connecting pipe and support column, enables the support columns on both sides to automatically insert into both ends of the pipe fitting, supporting and fixing the pipe fitting without the need for manual clamping, reducing the degree of manual intervention and improving the continuity and processing efficiency of hot-dip galvanizing of the pipe fitting.

[0017] 2. This invention, through the cooperation of motor two, sprocket one, sprocket two, chain, slider one, and guide component, enables a height difference to be formed between the two supporting columns, thereby causing the pipe fitting to tilt and achieving posture adjustment during the hot-dip galvanizing process. Compared to existing methods that require multiple hoisting devices to coordinate the adjustment of the pipe fitting's posture, this invention only needs to control motor two to complete the posture adjustment, making operation more convenient and control easier.

[0018] 3. This invention, by setting up a cleaning mechanism, uses an electric winding wheel, wire rope, slider, and cleaning plate to move impurities on the surface of the galvanizing solution forward and backward before the pipe fittings leave the pool. Through the cooperation of gears, racks, ratchet wheels, pawls, and guide grooves, the cleaning plate swings to push the galvanizing solution to flow, further pushing the scum away from the area above the pipe fittings. This reduces the amount of scum adhering to the surface of the pipe fittings, improves the galvanizing quality, and at the same time reduces the labor intensity of manual scum removal and the impact of exhaust gas on workers.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0024] This invention provides a lifting device for hot-dip galvanizing, such as... Figures 1-5 As shown, it includes: a fixed column 1, a connecting frame 2, a crossbeam 3, a guide component 4, a slider 1 5, a guide frame 6, a connecting pipe 7, a support frame 8, a support column 9, a fixed frame 10, a guide rail 11, a slider 2 12, a fixed rod 13, a threaded rod 14, a motor 15, a sprocket 16, a motor 2 17, a sprocket 2 18, and a chain 19; Fixed column 1 is fixedly connected to connecting frame 2, fixed column 1 is fixedly connected to crossbeam 3, crossbeam 3 is fixedly connected to guide component 4, guide component 4 is slidably connected to slider 1 5; there are two guide frames 6, each fixedly connected to two slider 1 5, guide frame 6 is slidably connected to connecting pipe 7, connecting pipe 7 is fixedly connected to support frame 8, support frame 8 is fixedly connected to multiple equally spaced support columns 9; there are two fixed frames 10, each fixedly connected to two guide components 4, fixed frame 10 is fixedly connected to guide rail 1 11, guide rail 1 11 is slidably connected to slider 2 12, slider 2 12 is fixedly connected to... There is a fixed rod 13, which is located inside the connecting pipe 7 and the two are slidably connected; a sprocket 16 is rotatably connected to the connecting frame 2, and a motor 17 is fixedly connected to the connecting frame 2. The output shaft of the motor 17 is fixedly connected to the sprocket 16; a fixed frame 10 is rotatably connected to a sprocket 18; a chain 19 is connected between the sprocket 16 and the sprocket 18; the chain 19 is fixedly connected to the slider 5; a guide rail 11 is rotatably connected to a threaded rod 14, which passes through the slider 12 and the two are threadedly connected; a motor 15 is fixedly connected to the guide rail 11, and the output shaft of the motor 15 is fixedly connected to the threaded rod 14.

[0025] Connect the connecting frame 2 to the working end of the lifting platform, and then move the lifting device through the working end of the lifting platform. In the initial state, the two sliders 5 are at the same horizontal height. When in use, control the lifting hook to move downward until the support columns 9 on both sides are at both ends of the pipe fitting. Start the motor 15. The output shaft of the motor 15 drives the threaded rod 14 to rotate. The threaded rod 14 drives the slider 12 to slide along the guide rail 11 through the thread. The slider 12 drives the connecting pipe 7 to slide laterally along the guide frame 6 through the fixed rod 13. The two connecting pipes 7 move closer to each other, so that the support columns 9 on both sides are inserted into both ends of the pipe fitting. Turn off the motor 15. 5. Then, control the working end of the elevator to move upward, the support column 9 drives the pipe to move, and transfer the pipe to the top of the galvanizing tank. Then start the motor 17. The output shaft of the motor 17 drives the sprocket 16 to rotate. The sprocket 16 drives the chain 19 to move to one side. Taking the chain 19 moving to the right as an example, the right slider 5 moves downward along the guide 4, while the left slider 5 moves upward along the guide 4. The two sprockets 18 play a guiding role. The support columns 9 on both sides have a height difference. Although the straight distance between the support columns 9 on both sides increases, the ends of the support columns 9 still support the pipe. Then turn off the motor 17.

[0026] Then, control the working end of the lifting platform to move downwards, so that the connecting pipe 7 and the fittings are immersed in the galvanizing bath for galvanizing. After galvanizing is completed, control the working end of the lifting platform to move the lifting device upwards, remove the fittings from the galvanizing bath and transfer them to the designated position. Through the above operation, it is easy to transfer the fittings, and only the motor 17 needs to be controlled to control the posture of the fittings during the galvanizing process, reducing the difficulty of control and improving the efficiency of galvanizing.

[0027] like Figures 5-9 As shown, it also includes a cleaning mechanism, which is located between two guide members 4. The cleaning mechanism includes: guide rail 20, slider 3 21, elastic element 1 210, support shaft 22, cleaning plate 23, gear 24, ratchet 25, torsion spring 26, fixed seat 27, sliding frame 28, rack 29, spring 30, guide shell 31, connecting block 32, fixed plate 33, guide groove 34, fixed sleeve 35, pawl 36, elastic element 2 37, guide wheel 38, electric winding wheel 39, and wire rope 40. Two guide rails 20 are provided, each fixed to one of the two guide members 4. Two sliders 3 21 are slidably connected to each guide rail 20. An elastic element 1 210 is fixed between each slider 3 21 and the guide rail 20. A support shaft 22 rotatably connects the two sliders 3 21 on both sides. Two cleaning plates 23 are provided, each fixed to one of the two support shafts 22. The two cleaning plates 23 are arranged in a V-shape. A gear 24 and a ratchet 25 are fixed to the support shaft 22. A torsion spring 26 is fixed between the sliders 3 21 and the ratchet 25. Two fixed seats 27 are fixed to the upper side of the guide rail 20. A sliding frame 28 is slidably connected to each fixed seat 27. A rack 29 is fixed to each sliding frame 28, and the rack 29 meshes with the adjacent gear 24. A support shaft 22 is rotatably connected to the two fixed seats 27. There is a spring 30; a guide shell 31 is fixedly connected to the slider 31, and a connecting block 32 is slidably connected to the guide shell 31; two fixing plates 33 are fixedly connected to the lower side of the guide rail 20, and the fixing plates 33 are provided with guide grooves 34, and the connecting block 32 is located in the guide grooves 34; the guide grooves 34 include a middle horizontal section and downward inclined sections respectively connected to both ends of the middle horizontal section; a fixing sleeve 35 is fixedly connected to the connecting block 32, and a pawl 36 is slidably connected to the fixing sleeve 35, the pawl 36 limits the ratchet 25, and an elastic element 2 37 is fixedly connected between the pawl 36 and the fixing sleeve 35; two guide wheels 38 are fixedly connected to the guide rail 20, and electric winding wheels 39 are fixedly connected to both sides of the guide element 4; a steel wire rope 40 is fixedly connected between the electric winding wheel 39 and the slider 31, and the steel wire rope 40 is wound around the outside of the guide wheel 38.

[0028] When the pipe fitting is placed in the galvanizing bath, the two cleaning plates 23 move downwards with the pipe fitting, extending into the galvanizing bath with their lower ends below the galvanizing liquid level. When the pipe fitting is ready to be removed from the galvanizing bath after galvanizing, the electric winding wheel 39 is activated. The electric winding wheel 39 winds up the wire rope 40, which, guided by the guide wheel 38, pulls the slider 21 along the guide rail 20. The elastic element 210 is stretched, and the sliders 21 on both sides move the cleaning plates 23 via the support shaft 22. 3. Moving back and forth, the cleaning plate 23 pushes impurities on the liquid surface to the front and back sides, moving them away from the top of the pipe fitting. Under the elastic force of the torsion spring 26, the cleaning plate 23 moves in an inclined state. The slider 31 drives the guide shell 31 and the connecting block 32 to move synchronously. The connecting block 32 slides in the guide groove 34 of the fixed plate 33, guiding the connecting block 32. When the connecting block 32 moves to the horizontal position of the guide groove 34, the connecting block 32 slides upward along the guide shell 31. The connecting block 32, through the fixed sleeve 35 and the elastic element 2 37, carries... When the movable pawl 36 moves and contacts the ratchet 25, it limits the ratchet 25, preventing the support shaft 22 from rotating along the slider 21. When the gear 24 contacts the rack 29, since the support shaft 22 and gear 24 cannot rotate, the gear 24 will push the rack 29 to move. The rack 29 slides along the fixed seat 27 via the sliding frame 28, compressing the spring 30. When the connecting block 32 moves to the inclined position of the guide groove 34, the guide groove 34 guides the connecting block 32, causing the connecting block 32 to slide downward along the guide shell 31. Pawl 36 separates from ratchet 25. Under the elastic force of spring 30, sliding frame 28 and rack 29 quickly return to their original positions. Rack 29 drives gear 24 to rotate, gear 24 drives support shaft 22 to rotate, and support shaft 22 drives cleaning plate 23 to swing momentarily, causing cleaning plate 23 to swing to a vertical position. During the swinging process of cleaning plate 23, cleaning plate 23 pushes the galvanizing liquid, causing the galvanizing liquid to flow forward and backward. Under the action of the flow of galvanizing liquid, impurities are further moved to the front and back sides of the galvanizing pool, and the impurities are moved away from the pipes, making it easier to clean the impurities in the future.

[0029] Then, the elevator is controlled to remove the pipe from the galvanizing tank and transfer it to the designated position. Then, the electric winding wheel 39 is controlled to release the wire rope 40. Under the tension of the elastic element 210, the slider 21 slides back to its original position along the guide rail 20. When the slider 21 resets, the pawl 36 will contact the ratchet 25 again. When the gear 24 slides along the rack 29, the gear 24 will drive the support shaft 22 to rotate. During this process, the pawl 36 does not limit the ratchet 25, and under the elastic force of the elastic element 37, the pawl 36 is in contact with the outer side of the ratchet 25. When the slider 21 resets, the lower ends of the two cleaning plates 23 contact again, the pawl 36 separates from the ratchet 25, and then the electric winding wheel 39 is turned off.

[0030] Working principle of the invention: In use, first connect the connecting frame 2 to the working end of the lifting machine, and then move the entire lifting device through the lifting machine. In the initial state, the two sliders 5 are at the same horizontal height, and the two support columns 9 are set opposite each other. When it is necessary to clamp the pipe fitting, the lifting machine moves the lifting device down, so that the two support columns 9 correspond to the two ends of the pipe fitting respectively; then start the motor 15, which drives the threaded rod 14 to rotate. The threaded rod 14 drives the slider 12 to move along the guide rail 11. The slider 12 drives the connecting pipe 7 to slide laterally along the guide frame 6 through the fixed rod 13, so that the two connecting pipes 7 are brought closer to each other, thereby allowing the two support columns 9 to be inserted into the two ends of the pipe fitting, realizing the support and clamping of the pipe fitting.

[0031] After the pipe fitting is supported, the elevator lifts the lifting device to move the pipe fitting above the galvanizing tank. Then, motor 217 is started, which drives sprocket 16 to rotate. Sprocket 16 drives chain 19 to move, and chain 19 further drives the two sliders 15 on both sides to move up and down in opposite directions along the guide 4, so that the two support columns 9 on both sides form a height difference.

[0032] During the movement of support column 9, it remains inserted at both ends of the pipe fitting. Therefore, the pipe fitting is reliably supported while tilting, thereby adjusting its posture upon entering the galvanizing bath. The posture of the pipe fitting during hot-dip galvanizing can be changed simply by controlling motor 17, reducing control complexity and improving operational efficiency.

[0033] After posture adjustment, the lifting platform lowers the lifting device, immersing the pipe fitting in the galvanizing bath for hot-dip galvanizing. During the insertion process, the cleaning mechanism descends synchronously with the lifting device, with the lower ends of the two cleaning plates 23 submerged below the galvanizing solution surface and positioned above the pipe fitting. Once the pipe fitting is galvanized and ready for removal, the electric winding wheel 39 is activated, winding the wire rope 40. Guided by the guide wheel 38, the wire rope 40 pulls the slider 21 along the guide rail 20, stretching the elastic element 210. The sliders 21 on both sides, via the support shaft 22, move the cleaning plates 23 forward and backward respectively, pushing impurities on the galvanizing solution surface away from the area above the pipe fitting.

[0034] During the movement of slider 31, connecting block 32 moves synchronously with guide shell 31 and is guided by guide groove 34 on fixed plate 33. When connecting block 32 moves to the horizontal section of guide groove 34, connecting block 32 moves upward along guide shell 31, driving fixed sleeve 35 and pawl 36 to approach ratchet 25. Pawl 36 limits ratchet 25, preventing support shaft 22 from rotating temporarily. At this time, gear 24 contacts rack 29, and gear 24 pushes rack 29 and sliding frame 28 to move and compress spring 30. When connecting block 32 continues to move to the inclined section of guide groove 34, connecting block 32 moves downward under the action of guide groove 34, causing pawl 36 to separate from ratchet 25. Spring 30 releases its elastic force and pushes rack 29 to quickly reset. Rack 29 drives gear 24 to rotate, and gear 24 drives support shaft 22 and cleaning plate 23 to swing instantly to a vertical state. When the cleaning plate 23 swings, it pushes the galvanizing liquid to flow, causing impurities on the liquid surface to move further to the front and back sides of the galvanizing pool, preventing impurities from adhering to or remaining above the pipes, making it easier to remove the pipes and clean the impurities later.

[0035] After the pipe fitting is removed and transferred to the designated position, the electric winding wheel 39 is controlled to release the wire rope 40. Under the pulling force of the elastic element 210, the slider 21 resets along the guide rail 20. During the reset process, the pawl 36 is in contact with the outer side of the ratchet 25 but does not form a limit. The gear 24 can move relative to the rack 29 and drive the support shaft 22 to reset. After the slider 21 resets, the two cleaning plates 23 return to their initial state, the pawl 36 separates from the ratchet 25, and the electric winding wheel 39 stops working.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
