Description

Technical Field

[0001] This utility model belongs to the field of galvanizing technology, specifically relating to a galvanizing basket hanging device, and more particularly to a hanging device for immersing zinc baskets in solution. Background Technology

[0002] Galvanizing is an important metal surface protection process used to improve the corrosion resistance of workpieces and extend their service life. In particular, in the production of small metal workpieces (such as screws, nuts, washers, etc.), batch galvanizing is usually required to ensure a uniform coating. In actual production, in order to improve operational efficiency, small workpieces need to be loaded into galvanizing baskets (hereinafter referred to as "galvanizing baskets"), suspended into the zinc bath by a suspension device for immersion galvanizing, and removed by a lifting device after the process is completed.

[0003] In related technologies, due to the high temperature of the galvanizing solution, which poses certain dangers, the commonly used galvanizing basket suspension device is an open hook. The hook is used to mechanically attach and fix the basket, and the basket is lifted by pulling the hook. However, before the hook completely lifts the basket out of the galvanizing solution, the basket is still immersed in the galvanizing solution. The buoyancy and fluid pressure will aggravate the swing of the basket, and the open hook may disengage under the swing of the basket, posing a risk of the basket falling.

[0004] Therefore, how to solve the problem of zinc basket swing causing it to detach from the hook is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0040] Research has revealed the following drawbacks of existing technologies: Due to the high temperature of the galvanizing solution, which poses certain risks, the commonly used galvanizing basket suspension device is an open hook. The hook is mechanically attached to secure the basket, and the basket is lifted by pulling the hook. However, before the basket is completely lifted out of the molten zinc, it remains submerged. Buoyancy and fluid pressure exacerbate the basket's swaying, causing the open hook to disengage during the swaying, posing a risk of the basket falling.

[0041] Therefore, how to solve the problem of zinc basket swing causing it to detach from the hook is a technical problem that urgently needs to be solved in this field.

[0042] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] like Figures 1 to 4 As shown, some embodiments provide a hanging device for zinc basket immersion, including: a self-locking hook mechanism 3, which is suitable for hanging a basket 7, the basket 7 being provided with a crossbar, hanging hole or handle matching the self-locking hook mechanism 3; the composition structure of the self-locking hook mechanism 3 is described in detail below, the self-locking hook mechanism 3 includes: a connecting member 4, which has an internal telescopic channel 41 for a spring 512, and a through hole 42 on its side wall, the through hole 42 communicating with the lower half of the telescopic channel 41; a hook 5, the handle 51 extending upward from the hook portion 52 is disposed in the telescopic channel 41 and elastically connected with the spring 512. In this configuration, the handle 51 and spring 512 are positioned within the telescopic channel 41, with the bottom end of the handle 51 extending below the telescopic channel 41. The hook 52 is connected to the bottom end of the handle 51. A drive unit 514 is provided on the side wall of the handle 51, facing the through hole 42. A locking member 6 is rotatably connected to the side wall of the through hole 42, with one end of the locking member 6 passing through the through hole 42 and engaging with the drive unit 514. When the hook 5 is under load and the connecting member 4 is raised, the drive unit 514 triggers the other end of the locking member 6 to close the hook 52 downwards. In the initial state, as shown... Figure 2 As shown, the spring 512 will pull the handle 51 to a certain position. At this time, the distance between the opening positions of the locking part 6 and the hook part 52 is the largest. When the basket 7 is hung on the hook part 52, the lifting device will lift the hook mechanism 3 upward. Since the basket 7 is heavy, it will not be pulled up at the same time. At this time, as shown in Figures 2 and 3, the connecting part 4 and the locking part 6 move simultaneously in the F1 direction. The hook 5 remains stationary, and the locking part 6 will move in the F2 direction until the other end of the locking part 6 closes the hook part 521 downward.

[0046] The telescopic channel 41 has a T-shaped vertical cross-section, including an upper wide portion 411 and a lower narrow portion 412. The upper wide portion 411 communicates with the through hole 42. The handle 51 includes a stop block 511, which can only move within the upper wide portion 411. The bottom surface of the upper wide portion 411 is used to restrict the stop block 511 from moving further downward. It is set within the upper wide portion 411 by a spring 512. A connecting rod 513 is provided on the bottom surface of the stop block 511. The lower half of the connecting rod 513 passes through the lower narrow portion 412 and extends below the connector 4, connecting with the hook portion 52. The drive unit 514 includes a rack 515, which is provided on one side of the connecting rod 513. One end of the locking member 6 is provided with a sector-shaped gear 61 that meshes with the rack 514. The connector 4 is adapted for vertical lifting to allow for... Rack 514 drives sector gear 61 to rotate When the other end of the locking member 6 closes the hook 52 downwards, and the connecting member 4 is adapted to be lifted vertically, the locking member 6 is lifted along with the connecting member 4 because the rack 514 and the hook 52 are temporarily stationary. At this time, the rack 514 drives the fan-shaped gear disk 61 to rotate until the stop block 511 abuts against the bottom surface of the upper wide part 411, which is also the other end of the locking member 6 abuts against the open end of the hook 521. Then, the lifting continues, and the connecting member 4 and the hook 5 move upwards in sync.

[0047] To improve closure stability and to allow the hook 5 to attach to the basket 7 within a certain cross-section, the hook portion 52 is U-shaped, capable of hooking onto attachments with circular or irregular cross-sections. Specifically, the hook portion 52 includes an arc-shaped portion 522 and two vertical portions 521. The arc-shaped portion 522 connects between the two vertical portions 521, and one of the vertical portions 521 is connected to the connecting rod 513. The other vertical portion 521 is adapted to abut against the locking member 6. A locking notch 526 is provided on the other vertical portion 521; wherein the locking member 6 is adapted to rotate to abut against the locking notch 526.

[0048] To achieve the desired initial effect after the suspended basket 7 contacts the hook 5, at least two grooves 523 are provided on the arc-shaped portion 522, and positioning stops 524 are provided inside the grooves through flexible parts 525. The hooking surface of the suspended basket 7 is adapted to compress part of the positioning stops 524 into the grooves 523. One pair of positioning stops 524 is adapted to be clamped on both sides of the hooking surface of the suspended basket 7. The setting of the positioning stops 524 further enhances the stability of the suspended basket 7 when it is lifted in the zinc liquid and reduces its swaying amplitude.

[0049] Some embodiments provide a hanging device for zinc basket immersion, including: a moving track 1 disposed above the basket 7; a chain structure 2 adapted to move on the moving track 1; and a self-locking hook mechanism 3 connected to the chain structure 2. The self-locking hook mechanism 3 is movable on the moving track 1 via the chain structure 2 to adapt to baskets 7 of different sizes. The self-locking hook mechanism 3 includes: a connector 4 connected to the chain structure 2; and a hook 5, the hook portion 52 having at least two grooves 523 on its arcuate portion 522, with positioning stops 524 provided in the grooves 523 via flexible members 525. The hooking surface of the basket 7 is adapted to compress part of the positioning stops 524 within the grooves 523, and a pair of positioning stops 524 are adapted to clamp on both sides of the hooking surface of the basket 7 to prevent the basket 7 from moving.

[0050] The connector 4 has an internal telescopic channel 41 for the spring 512 and a through hole 42 on its side wall; the handle 51 extending upward from the hook 52 is disposed in the telescopic channel 41 and elastically cooperates with the spring 512; the side wall of the handle 51 is provided with a driving part 514; the locking part 6 has one end passing through the through hole 42 and cooperating with the driving part 514. When the hook 5 is under load and the connector 4 is raised, the driving part 514 triggers the other end of the locking part 6 to close the hook 52 downward.

[0051] The telescopic channel 41 has a T-shaped vertical cross-section, including an upper wide portion 411 and a lower narrow portion 412. The upper wide portion 411 communicates with the through hole 42. The handle portion 51 includes a stop block 511, which is set inside the upper wide portion 411 by a spring 512. A connecting rod 513 is provided on the bottom surface of the stop block 511. The lower half of the connecting rod 513 passes through the lower narrow portion 412 and extends below the connector 4, and connects with the hook portion 52. The drive portion 514 includes a rack 515, which is set on one side of the connecting rod 513. One end of the locking member 6 is provided with a sector-shaped gear 61 that meshes with the rack 514. The connector 4 is adapted to be vertically lifted so that the sector-shaped gear 61 is driven to rotate by the rack 514, so that the other end of the locking member 6 closes the hook portion 52 downward.

[0052] The hook portion 52 is U-shaped, comprising an arc-shaped portion 522 and two vertical portions 521. The arc-shaped portion 522 connects between the two vertical portions 521, and one of the vertical portions 521 is connected to the connecting rod 513. The other vertical portion 521 is adapted to abut against the locking member 6. A locking notch 526 is provided on the other vertical portion 521; wherein the locking member 6 is adapted to rotate to abut against the locking notch 526.

[0053] In summary, this utility model, by setting a self-locking hook mechanism 3, connects the hook 52 to the basket 7. After the lifting and hanging device is lifted, the locking member 6 rotates under the drive of the handle 51, achieving the effect of closing the opening of the hook 52. This places the connection between the basket 7 and the hanging device in a closed loop, preventing the basket 7 in the zinc liquid from detaching from the hanging device due to buoyancy swing, and effectively enhancing the stability of the zinc basket gripping.
