Description

Technical Field

[0001] This application relates to the field of galvanizing technology, and in particular to a hanger for hot-dip galvanizing U-shaped steel. Background Technology

[0002] U-shaped steel is a type of steel with a U-shaped cross-section; it is widely used in construction, transportation, and manufacturing industries. Currently, galvanizing can be applied to the surface of U-shaped steel to improve its corrosion resistance and wear resistance. The main galvanizing processes for U-shaped steel include hot-dip galvanizing, electro-galvanizing, and cold spray galvanizing.

[0003] To galvanize U-shaped steel using a hot-dip galvanizing process, the U-shaped steel is hoisted into a molten zinc bath at a temperature of approximately 460°C. After the high-temperature zinc liquid has fully reacted with the U-shaped steel, it is then hoisted out of the molten zinc bath.

[0004] In existing technologies, overhead cranes are typically used to lift U-shaped steel sections. This involves securing the U-shaped steel to a lifting device, with a hook on the roof of the factory connected to the device; the overhead crane then moves the U-shaped steel. After the U-shaped steel reacts with the molten zinc, a layer of dross forms on the surface of the zinc solution. This dross consists of zinc oxide, zinc-iron alloy slag, and other metallic impurities. Before lifting the U-shaped steel from the molten zinc, workers need to use tools to skim off and remove this dross to prevent it from adhering to the U-shaped steel and affecting its electroplating effect and appearance.

[0005] Due to the high temperature around the molten zinc bath, the working environment is quite harsh; it takes a lot of time for workers to clean the scum on the zinc liquid, which affects the efficiency of hot-dip galvanizing of U-shaped steel. Utility Model Content

[0006] In order to improve the galvanizing efficiency of U-shaped steel, this application provides a hanger for hot-dip galvanizing U-shaped steel.

[0007] This application provides a hanging fixture for hot-dip galvanizing U-shaped steel, which adopts the following technical solution:

[0008] A hanging device for hot-dip galvanizing U-shaped steel includes a hanging basket and a collecting assembly. The hanging basket has a receiving groove for receiving U-shaped steel and lifting lugs for connecting to a hook. The collecting assembly includes guide members and a collecting member. Two guide members are horizontally fixed to both sides of the hanging basket along its width. The collecting member is disposed between the two guide members and is slidably connected to the guide members. The collecting member slides along the length of the hanging basket, and a distance is provided between the collecting member and the opening of the receiving groove. The collecting member is used to skim off slag from the surface of the molten zinc.

[0009] By adopting the above technical solution, when the overhead crane moves the U-shaped steel using the lifting device, the crane will tilt and lift the U-shaped steel out of the molten zinc bath. Before the U-shaped steel is exposed to the zinc liquid, the collecting device will slide along the inclined guide and skim the scum on the surface of the zinc liquid aside; thereby reducing the workload of the workers and improving the efficiency of hot-dip galvanizing of U-shaped steel.

[0010] Meanwhile, before the U-shaped steel is lifted out of the molten zinc, the collecting components clean off the slag on the surface of the molten zinc. This greatly reduces the risk of slag adhering to the U-shaped steel before it is lifted out of the molten zinc, improves the galvanizing effect of the U-shaped steel, reduces the amount of galvanized U-shaped steel to be processed, and improves production efficiency.

[0011] Optionally, the collection assembly further includes a suspending element, which is fixedly connected to the collection element; when the suspending element floats on the zinc liquid, the bottom of the collection element is submerged in the zinc liquid.

[0012] By adopting the above technical solution, during the process of the lifting device detaching from the zinc liquid, the suspension component allows the collecting component to float above the zinc liquid, so that the collecting component can slowly collect the scum to the side, thereby improving the collecting effect of the collecting component on the scum.

[0013] Optionally, along the length of the guide member, the guide member includes a first end and a second end disposed opposite to each other, the first end being removed from the molten zinc before the second end; both the first end and the second end are disposed on the outer periphery of the basket, and both the first end and the second end are provided with a clearance distance from the basket.

[0014] By adopting the above technical solution, the distance between the two ends of the guide is greater than the length of the basket, that is, the moving path of the collecting component is greater than the length of the basket; thereby reducing the impact of scum on the U-shaped steel in the basket.

[0015] Optionally, the first end of the guide member is provided with a first limiting groove, and the second end of the guide member is provided with a second limiting groove. The first limiting groove and the second limiting groove are used to temporarily fix the collecting member; and the distance between the first limiting groove and the second limiting groove is greater than the length of the basket.

[0016] By adopting the above technical solution, the collecting component is temporarily fixed by the first limiting groove and the second limiting groove to reduce the slippage of the collecting component, so as to facilitate the movement of the crane and the U-shaped steel.

[0017] Optionally, both the first limiting groove and the second limiting groove are arc-shaped grooves, and the groove depth of the first limiting groove is less than the groove depth of the second limiting groove.

[0018] By adopting the above technical solution, it is easier to move the collection component from the first end of the lifting device to the second end of the lifting device, thereby improving the collection effect of the collection component on scum.

[0019] Optionally, the distance between the two guide members is greater than the width of the groove of the receiving slot.

[0020] By adopting the above technical solution, the collection width of the collecting component is greater than the opening width of the receiving tank, thereby reducing the impact of scum on the U-shaped steel in the basket.

[0021] Optionally, the bottom of the suspended platform is provided with a support rod, which is used to support the U-shaped steel and is arranged along the width direction of the suspended platform; the support rod is fitted with a sleeve, which is used to abut against the U-shaped steel.

[0022] By adopting the above technical solution, the sleeve is fitted onto the support rod, which facilitates the sliding of the U-shaped steel when the basket tilts; this allows the U-shaped steel to fully contact the zinc liquid phase, improving the uniformity of galvanizing the U-shaped steel.

[0023] Optionally, the outer periphery of the sleeve is provided with a plurality of through holes in a ring.

[0024] By adopting the above technical solution and opening several through holes in the sleeve, the zinc liquid between the sleeve and the support rod can be discharged in time when the basket is lifted away from the zinc liquid, thereby improving the galvanizing efficiency of the U-shaped steel.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Before the U-shaped steel is exposed to the zinc liquid, the collecting device slides along the inclined guide and skims the scum on the surface of the zinc liquid aside; thereby reducing the workload of the workers and improving the efficiency of hot-dip galvanizing of U-shaped steel.

[0027] 2. During the process of the lifting device detaching from the molten zinc, the suspension component allows the collecting component to float above the molten zinc, so that the collecting component can slowly collect the scum to the side, thereby improving the collecting efficiency of the collecting component for scum.

[0028] 3. The sleeve is fitted onto the support rod, which facilitates the sliding of the U-shaped steel when the basket tilts; this allows the U-shaped steel to fully contact the molten zinc, improving the uniformity of the galvanizing of the U-shaped steel. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1 Section 7 provides further details regarding this application.

[0038] Example 1

[0039] This application discloses a hanging fixture for hot-dip galvanizing U-shaped steel. (Refer to...) Figure 1 The hanging equipment for hot-dip galvanizing U-shaped steel includes a hanging basket 1 and a collecting component 2. The collecting component 2 is fixedly connected to the hanging basket 1 and is positioned directly above the hanging basket 1. The hanging basket 1 is used to hold the U-shaped steel 3. The overhead crane at the top of the hot-dip galvanizing workshop moves the hanging basket 1 into the molten zinc bath 4 via a lifting rope 5, thereby depositing a zinc layer on the surface of the U-shaped steel 3. When the overhead crane moves the hanging basket 1 and the U-shaped steel 3 away from the molten zinc bath 4, the collecting component 2 is used to collect the scum on the surface of the zinc liquid, so that the hanging basket 1 and the U-shaped steel 3 can be lifted out of the molten zinc bath 4.

[0040] Reference Figures 2 to 4The suspended platform 1 includes a frame 11, a metal mesh panel 12, and partition fences 13. In this embodiment, the frame 11 is rectangular in plan view to accommodate the long U-shaped steel 3. Along the length of the frame 11, the metal mesh panel 12 is fixed to both ends of the frame 11; a clearance distance is provided between the U-shaped steel 3 and the metal mesh panel 12, and the metal mesh panel 12 is used to fix the U-shaped steel 3. Two partition fences 13 are provided, and along the width of the frame 11, the partition fences 13 are fixed at intervals on the bottom of the frame 11, and a clearance distance is provided between the partition fences 13 and the inner sidewall of the frame 11. The two partition fences 13 and the sidewall of the frame 11 form a receiving groove 15, which is used to receive the U-shaped steel 3.

[0041] Reference Figure 2 and Figure 4 The suspended platform 1 is equipped with multiple lifting lugs 14, which are located on the outside of the frame 11 and are used to connect to the lifting rope 5 of the gantry crane. Along the length of the suspended platform 1, the two opposite ends of the lifting device are defined as the first end 16 and the second end 17, respectively. The first end 16 is removed from the molten zinc before the second end 17. That is, when the gantry crane lifts the lifting device and the U-shaped steel 3 from the molten zinc, the gantry crane first lifts the first end 16 of the lifting device, so that the first end 16 of the lifting device is removed from the molten zinc; then, the gantry crane simultaneously lifts the first end 16 and the second end 17 of the lifting device, so that the lifting device and the U-shaped steel 3 are removed from the molten zinc at an angle.

[0042] Reference Figure 3 and Figure 5 The collecting component 2 includes a guide member 21, a collecting member 22, and a suspension member 23. Two guide members 21 are provided, horizontally fixed to both sides of the basket 1 along its width. The distance between the two guide members 21 is greater than the width of the opening of the receiving tank 15. The collecting member 22 is positioned between the two guide members 21, slidably connected to them. The collecting member 22 slides along the length of the basket 1, and a distance is provided between it and the opening of the receiving tank 15. The collecting member 22 is used to skim off scum from the surface of the molten zinc. The suspension member 23 is fixedly connected to the collecting member 22; when the suspension member 23 floats on the molten zinc, the bottom of the collecting member 22 is submerged in the molten zinc.

[0043] Reference Figure 3 and Figure 5In this embodiment, the guide member 21 is a horizontally arranged guide rod; when the locomotive drives the lifting device to tilt, the guide member 21 is also tilted. The first end 16 of the guide member 21 is provided with a first limiting groove 211, and the second end 17 of the guide member 21 is provided with a second limiting groove 212. The first limiting groove 211 and the second limiting groove 212 are used to temporarily fix the collecting member 22; and the distance between the first limiting groove 211 and the second limiting groove 212 is greater than the length of the basket 1. The distance between the two ends of the guide member 21 is greater than the length of the basket 1, that is, the moving path of the collecting member 22 is greater than the length of the basket 1; thereby reducing the impact of scum on the U-shaped steel 3 in the basket 1; and the collection member 22 is temporarily fixed by the first limiting groove 211 and the second limiting groove 212 to reduce the sliding of the collecting member 22, so as to facilitate the movement of the lifting device and the U-shaped steel 3 by the tractor.

[0044] Reference Figure 2 and Figure 3 In this embodiment, both the first limiting groove 211 and the second limiting groove 212 are arc-shaped grooves, and the groove depth of the first limiting groove 211 is less than the groove depth of the second limiting groove 212; so that the collecting component 22 can move from the first end 16 of the lifting device to the second end 17 of the lifting device, thereby improving the collecting effect of the collecting component 22 on the scum.

[0045] Reference Figure 5 In this embodiment, the collecting component 22 is provided with a mounting groove 221, and the guide component 21 is disposed in the mounting groove 221; the collecting component 22 is detachably connected to the guide component 21 by a flexible rope 222, thereby allowing the collecting component 22 to slide along the guide component 21.

[0046] Reference Figure 2 The suspending element 23 is fixedly connected to the collecting element 22. When the locomotive tilts and lifts the lifting device and U-shaped steel 3 away from the molten zinc, the suspending element 23 allows the collecting element 22 to float above the molten zinc, facilitating the slow collection of scum to the side and improving the scum collection efficiency. In this embodiment, the suspending element 23 is a hollow metal component, thus providing buoyancy to the collecting element 22.

[0047] The implementation principle of a hanger for hot-dip galvanizing U-shaped steel in this application embodiment is as follows:

[0048] Reference Figure 2 and Figure 4 When the overhead crane moves the U-shaped steel 3 using the lifting device, it tilts the U-shaped steel 3 out of the molten zinc bath 4. Before the U-shaped steel 3 is exposed to the molten zinc, the collecting component 22 slides along the inclined guide component 21 and skims the scum on the surface of the molten zinc aside, thereby reducing the workload of the workers and improving the efficiency of hot-dip galvanizing the U-shaped steel 3.

[0049] Meanwhile, before the U-shaped steel 3 is lifted out of the zinc liquid, the collecting component 2 cleans away the slag on the surface of the zinc liquid in advance; thus, before the U-shaped steel 3 is lifted out of the zinc liquid, the risk of slag adhering to the U-shaped steel 3 can be greatly reduced, the galvanizing effect of the U-shaped steel 3 can be improved, the amount of U-shaped steel 3 to be processed after galvanizing can be reduced, and the production efficiency can be improved.

[0050] Example 2

[0051] The difference between Example 2 and Example 1 is as follows:

[0052] Reference Figure 6 and Figure 7 The bottom of the suspended platform 1 is provided with a support rod 18, which is used to support the U-shaped steel 3. The support rod 18 is arranged along the width direction of the suspended platform 1. A sleeve 19 is sleeved on the support rod 18, which is used to abut against the U-shaped steel 3. In this embodiment, a plurality of through holes 191 are circumferentially opened on the outer periphery of the sleeve 19.

[0053] The implementation principle of a hanger for hot-dip galvanizing U-shaped steel in this application embodiment is as follows:

[0054] When the U-shaped steel 3 is placed in the basket 1, the bottom of the U-shaped steel 3 will contact the support rod 18 at the bottom of the basket 1, making it difficult for the zinc liquid phase to come into contact with this area of ​​the U-shaped steel 3, thus affecting the galvanizing effect of this area of ​​the U-shaped steel 3.

[0055] Reference Figure 6 and Figure 7 In this embodiment, the sleeve 19 is fitted onto the support rod 18, thereby facilitating the sliding of the U-shaped steel 3 when the basket 1 tilts; this allows the U-shaped steel 3 to fully contact the molten zinc, improving the uniformity of galvanizing. Specifically, when the U-shaped steel 3 is immersed in the molten zinc, the operator can control the crane to tilt the lifting device multiple times, ensuring that all areas of the U-shaped steel 3 fully contact the molten zinc, thus improving the uniformity of galvanizing.

[0056] Reference Figure 6 and Figure 7 By opening several through holes in the sleeve, the zinc liquid between the sleeve and the support rod can be discharged in time when the basket is lifted away from the zinc liquid, thereby improving the galvanizing efficiency of the U-shaped steel.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
