[0002] Hot-dip galvanizing is a process widely used for anti-corrosion treatment of steel surfaces. It forms a dense zinc layer on the surface of the steel by immersing the cleaned steel in molten zinc liquid, thereby achieving the effect of anti-corrosion and extending the service life. Due to its strong coating adhesion and good anti-corrosion effect, this process is widely used in construction, transportation, energy and other fields; however, traditional hot-dip galvanizing equipment and processes have many problems, including: the zinc liquid and the steel are relatively static, the fluidity between the two is relatively small, and the steel is stacked in a container, which leads to a large number of obstructed areas on the surface of the steel, resulting in the steel surface cannot be fully galvanized, and there are certain galvanizing dead angles.

[0014] The present invention provides a steel surface hot-dip galvanizing device for steel structure processing, which has the following beneficial effects:

[0015] 1. The hot-dip galvanizing equipment for steel surface processed by the steel structure, after the electric lifting rod 2 is activated to drive the paddle to return to the initial position, the electric lifting rod 1 and the electric lifting rod 2 are activated to drive the hanging barrel and the chassis to slowly descend and slowly sink into the zinc liquid. During this period, the zinc liquid will simultaneously pass through the spiral bevel and the straight through hole, as well as the annular gap between the hanging barrel and the chassis, enter the inner side of the hanging barrel and the chassis, and contact with the steel. After the zinc liquid has submerged all the steel surfaces, the stirring motor can be activated again to drive The paddles rotate counterclockwise in the zinc liquid to stir it, driving the zinc liquid to flow counterclockwise inside the hot-dip galvanizing tank. The power of the counterclockwise flow is used to push the zinc liquid that enters the inside of the suspension tube and chassis through the spiral bevel and straight through holes, thereby improving the fluidity between the zinc liquid and the steel, increasing the contact area between the zinc liquid and the steel, eliminating the contact dead angle between the zinc liquid and the steel, and accelerating the contact speed between the zinc liquid and the steel surface, thereby improving the efficiency of the equipment in galvanizing the steel surface, thereby improving the equipment's production efficiency in galvanizing steel.

[0016] 2. The hot-dip galvanizing equipment for the steel surface of the steel structure processing, by activating the electric lifting rod 2, performs periodic telescopic movement within the effective elastic range of the gasket spring, drives the blades on the long rod shaft to repeatedly squeeze the gasket spring, and uses the gasket spring to gently push the chassis part, so that periodic lifting and lowering movement occurs between the chassis part and the hanging barrel, so that the steel can move up and down in the vertical direction relative to the zinc liquid, further increasing the contact area between the steel and the zinc liquid, further expanding the fluidity between the zinc liquid and the steel, further eliminating the dead angle of steel galvanizing, and also accelerating the galvanizing process of the steel.

[0017] 3. The hot-dip galvanizing equipment for steel surface processed by the steel structure, through the blades with the help of the gasket spring, drives the chassis and the hanging barrel to move up and down in the vertical position, while using the gasket spring as an elastic buffer, avoiding the direct effect of the weight carried by the chassis on the blades, and protecting the normal use of the blades; at the same time, using the clamp rod on the chassis and the tension spring connected to the chassis, the chassis is made to perform elastic lifting and lowering movements in a small range in the vertical direction relative to the bottom of the hanging barrel, without shaking out the steel, and can guide part of the waste slag generated during the galvanizing of the steel into the hot-dip galvanizing tank through the spiral bevel, straight through hole and the annular gap between the chassis and the hanging barrel, so as to avoid the production of waste slag and affect the overall galvanizing effect of the steel, prevent the waste slag from blocking the surface of the steel over a large area, prevent the appearance of galvanized holes on the surface of the steel, and improve the galvanizing quality of the steel surface.

[0018] 4. The hot-dip galvanizing equipment for the steel surface of the steel structure processing can use the corrugated hose installed in a surrounding shape around the tension spring and the clamp rod to protect the above two structures to prevent waste slag from adhering to or clogging the tension spring and the clamp rod. It also prevents unnecessary adhesion and waste of zinc liquid on the surface of the tension spring and the clamp rod, and avoids unnecessary cost waste caused by zinc liquid entering the clamp cavity. While saving production costs, it can also ensure smooth up and down bouncing between the chassis and the suspension tube.

[0019] 5. The hot-dip galvanizing equipment for steel surface processed by the steel structure can use several convex spheres installed on the top of the chassis to place the steel on the top of the chassis, provide a horizontal support plane composed of points, lift the steel from the top of the chassis to move the height, and facilitate the contact between the zinc liquid and the bottom of the steel through the spiral bevel and the straight hole during the immersion of the steel in the zinc liquid, so as to avoid blocking the entrance of the zinc liquid from the bottom of the chassis to the top of the chassis. At the same time, it also eliminates the fitting contact phenomenon between the top of the chassis and the bottom of the steel, reduces the area of ​​the steel surface blocked, and increases the effective area of ​​the steel surface galvanized. At the same time, when the steel is taken out later, the frictionless characteristics of the curved surface of the convex sphere can be used to facilitate the sliding and removal of the steel on the top of the chassis. Whether it is direct grabbing or pushing the steel out from the inside of the hanging tube, it can reduce the wear risk of the chassis on the steel and avoid the risk of scratching and damaging the galvanized layer on the steel surface by the equipment.

[0043] When in use, the initial position of the hanging barrel 3 is: it is hoisted in the middle part just above the attached bucket body 5; the piston disc 44 is fitted on the inner bottom plate of the hot-dip galvanizing tank 4, the semicircular spring piece 48 is embedded in the inner wall of the hot-dip galvanizing tank 4, and the waste pipe 46 is in a closed state; a proper amount of zinc liquid is transported to the inside of the hot-dip galvanizing tank 4 through the feed pipe 47; at this time, the latch rod 35 is pulled out to open the movable door 31, and the steel is neatly placed inside the hanging barrel 3 through the feed and discharge pipe body 12, and then the movable door 31 is closed, so that the movable door 31 and the hanging barrel 3 form a complete cylindrical closed structure, and then the latch rod 35 is re-inserted on the other side of the movable door 31 and the hanging barrel 3 that is not hinged, and the movable door 31 is locked on the hanging barrel 3; then the first servo motor 9 is activated to drive the screw rod 10 to rotate counterclockwise on the hanger 2, so that the spline head 8 is guided straight along the straight rail 21 by the electric The lifting rod 1 6 and the electric lifting rod 2 7 jointly drive the hanging barrel 3 to translate toward the right end close to the first servo motor 9 until the hanging barrel 3 is moved to the top of the hot-dip galvanizing tank 4, and then the electric lifting rod 1 6 and the electric lifting rod 2 7 are activated and extended at the same time to lower the hanging barrel 3 to the inside of the hot-dip galvanizing tank 4, so that the steel is completely immersed in the molten zinc liquid, and a dense zinc layer is formed on the surface of the steel. After the galvanizing of the steel is completed, the electric lifting rod 1 6 and the electric lifting rod 2 7 are activated to rise at the same time, and the same operating steps as above are used for the return operation, and the return operation of the hanging barrel 3 is adjusted to the initial position, that is, the hanging barrel 3 is hoisted by the hanger 2 just above the attached bucket 5, and the galvanized steel can be taken out at this time, so as to continue to repeat the above operation, and the next batch of steel is galvanized, and the galvanizing operation is cyclically operated to realize the galvanizing of the surface of large quantities of steel.

[0044] Among them, when the return stroke of the hanging barrel 3 is adjusted to the initial position, at this time, the electric lifting rod 27 is activated to retract, driving the long rod shaft 111 connected to the bottom of the stirring motor 11, and the paddle blade 112 on the long rod shaft 111 is vertically contracted upward to vertically squeeze the gasket spring 113 at the bottom of the sliding sleeve 34, and elastically collide with the bottom of the chassis part 32, so that the chassis part 32 and the hanging barrel 3 shake up and down in the vertical direction, and the zinc liquid remaining on the hanging barrel 3 and the chassis part 32 is quickly shaken off into the attached bucket body 5, so as to avoid the zinc liquid from being spilled outside the hot-dip galvanizing tank 4 or the attached bucket body 5 along with the removal of the steel, and to avoid the zinc liquid from contaminating the inner side of the box body 1 and causing unnecessary cleaning work.

[0045] At the same time, this shaking action can also be used to shake the remaining waste slag into the attached bucket 5, and the attached bucket 5 can be used to separately collect and store the waste slag, thereby reducing the total amount of waste slag accumulated inside the hot-dip galvanizing tank 4 and eliminating the interference of some waste slag on the steel during the galvanizing process inside the hot-dip galvanizing tank 4.

[0046] The electric lifting rod 1 6 and the electric lifting rod 2 7 are activated at the same time. Before the hanging barrel 3 is lowered into the hot-dip galvanizing tank 4 for galvanizing, the electric lifting rod 2 7 can be activated alone to drive the paddle 112 installed on the long rod shaft 111 to pre-enter the zinc liquid inside the hot-dip galvanizing tank 4, so that the paddle 112 comes to the middle of the zinc liquid, and then the stirring motor 11 is activated to drive the paddle 112 on the long rod shaft 111 to rotate clockwise in the zinc liquid to stir the zinc liquid evenly, so that all the components in the zinc liquid can be evenly distributed in the hot-dip galvanizing tank 4, and the zinc liquid for galvanizing the steel surface is pre-treated to be evenly stirred, so that the galvanizing quality of the steel surface is guaranteed.

[0047] Then, the stirring motor 11 is turned off, and the electric lifting rod 27 is activated to drive the paddle 112 back to the initial position. At the same time, the electric lifting rod 16 and the electric lifting rod 27 are activated to drive the hanging barrel 3 and the chassis 32 to slowly descend and slowly sink into the zinc liquid. During this period, the zinc liquid will simultaneously pass through the spiral bevel 322 and the straight through hole 323, as well as the annular gap between the hanging barrel 3 and the chassis 32, enter the inner side of the hanging barrel 3 and the chassis 32, and contact with the steel. After the zinc liquid has submerged all the steel surfaces, the stirring motor 11 can be activated again to drive The paddle 112 rotates counterclockwise and stirs in the zinc liquid to drive the zinc liquid to flow counterclockwise inside the hot-dip galvanizing tank 4. The power of the counterclockwise flow is used to push the zinc liquid entering the inside of the hanging tube 3 and the chassis 32 through the spiral bevel 322 and the straight through hole 323, thereby improving the fluidity between the zinc liquid and the steel, increasing the contact area between the zinc liquid and the steel, eliminating the contact dead angle between the zinc liquid and the steel, and accelerating the contact speed between the zinc liquid and the steel surface, thereby improving the efficiency of the equipment in galvanizing the steel surface, thereby improving the production efficiency of the equipment in galvanizing the steel.

[0048] During this period, the electric lifting rod 27 can be activated to perform periodic telescopic movement within the effective elastic range of the gasket spring 113, driving the paddle 112 on the long rod shaft 111 to repeatedly squeeze the gasket spring 113, and the gasket spring 113 is used to gently push the chassis part 32, so that periodic lifting and lowering movement occurs between the chassis part 32 and the hanging tube 3, so that the steel can move up and down in the vertical direction relative to the zinc liquid, further increasing the contact area between the steel and the zinc liquid, further expanding the fluidity between the zinc liquid and the steel, further eliminating the blind spots of steel galvanizing, and also accelerating the galvanizing process of the steel.

[0049] Among them, when the paddle 112 drives the chassis 32 and the hanging tube 3 to move up and down in the vertical direction with the help of the gasket spring 113, the gasket spring 113 is used as an elastic buffer to avoid the direct effect of the weight carried by the chassis 32 on the paddle 112, thereby protecting the normal use of the paddle 112; at the same time, the clamping rod 321 on the chassis 32 and the tension spring 302 connected to the chassis 32 are used to make the chassis 32 relative to the bottom of the hanging tube 3 to perform elastic lifting and lowering movements in a small range in the vertical direction, without shaking out the steel, and at the same time, part of the waste slag generated during the galvanizing of the steel can be guided into the hot-dip galvanizing tank 4 through the spiral bevel 322, the straight through hole 323 and the annular gap between the chassis 32 and the hanging tube 3, so as to avoid the production of waste slag and affect the overall galvanizing effect of the steel, prevent the waste slag from blocking the surface of the steel over a large area, prevent the appearance of galvanizing holes on the surface of the steel, and improve the galvanizing quality of the steel surface.

[0050] During this period, the corrugated hose 303 installed in a surrounding shape around the tension spring 302 and the clamp rod 321 can be used to protect the above two structures to prevent waste slag from adhering to or clogging the tension spring 302 and the clamp rod 321, and also prevent unnecessary attachment and waste of zinc liquid on the surface of the tension spring 302 and the clamp rod 321, and avoid unnecessary cost waste caused by zinc liquid entering the clamp cavity 301, saving production costs while ensuring smooth up and down bouncing movement between the chassis 32 and the suspension tube 3.

[0051] The convex spheres 324 installed on the top of the chassis 32 can be used to provide a horizontal support plane composed of points for placing the steel on the top of the chassis 32, so that the steel can be lifted from the top of the chassis 32 to move the height, so that the zinc liquid can contact the bottom of the steel through the spiral bevel 322 and the straight through hole 323 when the steel is immersed in the zinc liquid, thereby avoiding blocking the entrance of the zinc liquid from the bottom of the chassis 32 to the top of the chassis 32, and also eliminating the chassis 32 The fitting contact phenomenon between the top and the bottom of the steel reduces the area of ​​the steel surface that is blocked and increases the effective area of ​​the steel surface that is galvanized. At the same time, when the steel is taken out later, the frictionless characteristic of the curved surface of the convex sphere 324 can be utilized to facilitate the sliding and removal of the steel on the top of the chassis part 32. Whether directly grabbing or pushing the steel out from the inside of the hanging tube 3, the hidden danger of wear of the chassis part 32 on the steel can be reduced, and the hidden danger of scratching and damaging the galvanized layer on the surface of the steel by the equipment can be avoided.

[0052] The second embodiment is based on the first embodiment. Figure 4As shown, a crescent-shaped filter bucket 51 is embedded and installed on the inner side of the attached bucket body 5 and close to the hot-dip galvanizing tank 4. Filter holes are provided on the side of the attached bucket body 5 close to the hot-dip galvanizing tank 4 and on the surface of the crescent-shaped filter bucket 51 for filtering the zinc liquid collected on the inner side of the attached bucket body 5. The filter holes are used to filter and guide the zinc liquid into the hot-dip galvanizing tank 4. The outer diameter of the hanging barrel 3 is equal to the inner radius of the hot-dip galvanizing tank 4, which is convenient for the hanging barrel 3 to move in a small range inside the hot-dip galvanizing tank 4, providing an effective activity space for the full contact between the zinc liquid and the steel. The transverse axis length and longitudinal width of the attached bucket body 5 are both larger than the outer diameter of the hanging barrel 3, so as to avoid the zinc liquid from leaking outside the attached bucket body 5 during the process of draining.

[0053] When in use, the attached bucket body 5 can also be used as a horizontal extension and expansion of the receiving space of the hot-dip galvanizing tank 4, providing an independent static drainage area for the steel after galvanizing, and can shake off the zinc liquid remaining on the steel, the hanging tube 3 and the chassis 32, and can also shake off part of the waste slag generated during galvanizing into the attached bucket body 5 and collect it separately, and can be recycled and reused through the double filtering effect of the crescent-shaped filter bucket 51 and the contact part of the attached bucket body 5 and the hot-dip galvanizing tank 4, and directly redirect this part of the zinc liquid back into the hot-dip galvanizing tank 4 through the attached bucket body 5, avoiding unnecessary loss of zinc liquid, and at the same time, under the thrust of the zinc liquid flowing into the hot-dip galvanizing tank 4, the attached bucket body 5 is helped to collect the waste slag to the inner side of the crescent-shaped filter bucket 51, so that the waste slag can be taken out from the attached bucket body 5 in a unified manner later, which is convenient for the quick treatment of this part of the waste slag.

[0054] The third embodiment is based on the first and second embodiments. Figure 5 As shown, a waste pipe 46 is connected to the outer surface of the hot-dip galvanizing tank 4 and the side away from the right angle frame 42, a feed pipe 47 is installed just above the waste pipe 46, and the feed pipe 47 is fixedly connected to the hot-dip galvanizing tank 4, and a semicircular spring piece 48 is embedded and installed on the inner surface of the hot-dip galvanizing tank 4 and the side close to the right angle frame 42. The semicircular spring piece 48 is made of elastic material as a whole and has deformation and rebound performance, and both ends of the semicircular spring piece 48 away from the right angle frame 42 are hinged to the hot-dip galvanizing tank 4, and the semicircular spring piece 48 is fixedly connected to the hot-dip galvanizing tank 4. The sheet 48 is connected to a worm 49 for rotation toward the middle of one side of the right-angle frame 42, and the worm 49 penetrates the hot-dip galvanizing tank 4 and is threadedly installed with the right-angle frame 42. A second servo motor 410 is fixedly installed on the right-angle frame 42, and a worm gear 411 is installed on the output end pin of the second servo motor 410. The worm gear 411 is meshed with the worm 49. The semicircular spring sheet 48 is scraped and installed on the top of the piston disc 44 through the worm gear 411 on the second servo motor 410 and the worm 49 on the right-angle frame 42.

[0055] When the equipment is shut down, the zinc liquid in the hot-dip galvanizing tank 4 can be left to stand for a period of time, the clean upper zinc liquid can be extracted, and then the hydraulic push rod 43 is activated to drive the piston plate 44 to rise, so that the top of the piston plate 44 rises to the position on the same plane as the bottom of the semicircular spring piece 48 under the vertical guidance of the guide plug rod 45, as shown in FIG. Figure 5 As shown; then the waste pipe 46 is opened to release the remaining liquid and collect it for processing, and then the second servo motor 410 is activated, and the meshing transmission of the worm wheel 411 and the worm 49 is used to drive the worm 49 to extend into the inside of the hot-dip galvanizing tank 4 under the guidance of the right-angle frame 42, and the semicircular spring piece 48 embedded in the inner wall of the hot-dip galvanizing tank 4 is pushed, and the semicircular spring piece 48 is used as a scraper to collect the waste residue remaining on the piston plate 44 to the vicinity of the waste pipe 46, so as to help the operator The staff assists in collecting and processing the waste residue inside the hot-dip galvanizing tank 4, speeds up the efficiency of cleaning the hot-dip galvanizing tank 4, and also lifts the waste residue at the bottom of the inside of the hot-dip galvanizing tank 4 to the height position in the middle of the inside of the hot-dip galvanizing tank 4, which saves half of the cleaning operation space for the operator, and lifts and collects the waste residue near the waste pipe 46 for convenient discharge, thereby realizing the functional characteristics of the equipment that can be easily cleaned, saving the cleaning and maintenance time of the equipment, and improving the practicality and self-cleaning efficiency of the equipment.
