A multi-directional hanging device for hot-dip galvanizing tanks

Abstract

This utility model discloses a multi-directional hanging device for hot-dip galvanizing tanks, including a support plate. Two sets of support mechanisms for supporting steel components are fixed to the bottom of the support plate. Each support mechanism includes an outer support guide rail group and an inner support guide rail group, with two sets of each. The two sets of outer support guide rail groups are symmetrically fixed to both ends of the bottom of the support plate, and the two sets of inner support guide rail groups are symmetrically fixed to both ends of the bottom of the support plate and located inside the two sets of outer support guide rail groups. By setting two independently controllable support mechanisms (outer and inner support guide rail groups), the clamping state can be selectively switched during the hot-dip galvanizing process. Areas previously blocked by the lifting device can now fully contact the molten zinc, significantly reducing the galvanizing blind spots caused by fixed contact in traditional lifting devices and improving the integrity of the galvanizing on the steel component surface.

Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a multi-directional hanging device for hot-dip galvanizing tanks. Background Technology

[0002] During hot-dip galvanizing, steel components are placed into the hot-dip galvanizing tank using a lifting device, where molten zinc forms a dense protective film on the surface of the steel components. To reduce blind spots during galvanizing, existing lifting devices generally have a narrower contact area with the steel components. For example, CN210944515U describes a lifting device for hot-dip galvanizing steel components of power transmission towers, which supports the steel components and includes a bearing plate and several support rods. Two sets of support rods are vertically fixed to both ends of the bearing plate, and a crossbar connects the two sets of support rods at both ends.

[0003] Despite minimizing the contact area with steel components, blind spots in the contact area between the existing lifting equipment and the steel components are still unavoidable. Furthermore, simply reducing the contact area can also affect the overall strength of the lifting equipment. Utility Model Content

[0004] The purpose of this invention is to provide a multi-directional hanging device for hot-dip galvanizing tanks, so as to reduce the galvanizing blind zone caused by the contact of the hanging device during hot-dip galvanizing of steel components, and at the same time improve the adaptability and clamping stability of steel components of different specifications.

[0005] This utility model provides the following technical solution: a multi-directional hanging device for hot-dip galvanizing tanks, characterized in that: it includes a bearing plate, and two sets of support mechanisms for supporting steel components are fixed at the bottom of the bearing plate. The support mechanism includes an outer support guide rail group and an inner support guide rail group, with two sets of both the outer and inner support guide rail groups. The two sets of outer support guide rail groups are symmetrically fixed at both ends of the bottom of the bearing plate, and the two sets of inner support guide rail groups are symmetrically fixed at both ends of the bottom of the bearing plate and located inside the two sets of outer support guide rail groups. Upper clamping plates and lower clamping plates for clamping steel components are slidably provided inside the two sets of outer support guide rail groups and the two sets of inner support guide rail groups. Bidirectional threaded rods are rotatably provided inside the two sets of outer support guide rail groups and the two sets of inner support guide rail groups. The two ends of the bidirectional threaded rods are threadedly connected to the upper clamping plate and the lower clamping plate, respectively. A driving mechanism for driving the bidirectional threaded rods to rotate is provided on the bearing plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] 1) By setting up two independently controllable support mechanisms, the outer support guide rail group and the inner support guide rail group, the clamping state can be selectively switched during the hot-dip galvanizing process. The parts that were originally blocked by the lifting tool can now fully contact the molten zinc, which greatly reduces the galvanizing blind spots caused by the fixed contact of traditional lifting tools and improves the integrity of the galvanizing on the surface of steel components.

[0008] 2) The upper clamping plate is equipped with an adjustable screw and a clamping plate, which can flexibly adjust the clamping position according to the thickness difference of the steel components, ensuring stable clamping of steel components of different specifications. This solves the problem that traditional lifting tools are difficult to adapt to steel components of various sizes, and enhances the versatility of the device. Attached Figure Description

[0014] Example 1

[0015] A multi-directional hanging device for hot-dip galvanizing tanks includes a support plate 9. Two sets of support mechanisms for supporting steel components are fixed to the bottom of the support plate 9. Each support mechanism includes an outer support guide rail group 6 and an inner support guide rail group 7, both vertically arranged. There are two sets of each type of support mechanism. The two sets of outer support guide rail groups 6 are symmetrically fixed at both ends of the bottom of the support plate 9, and the two sets of inner support guide rail groups 7 are symmetrically fixed at both ends of the bottom of the support plate 9 and located inside the two sets of outer support guide rail groups 6. The outer support guide rail group 6 and the two inner support guide rail groups 7 are each equipped with an upper clamping plate 12 and a lower clamping plate 13 for clamping steel components. Both the outer support guide rail group 6 and the two inner support guide rail groups 7 are equipped with a bidirectional threaded rod 10. The two ends of the bidirectional threaded rod 10 are threadedly connected to the upper clamping plate 12 and the lower clamping plate 13, respectively. The bearing plate 9 is equipped with a drive mechanism for driving the bidirectional threaded rod 10 to rotate. The drive components of the two support mechanisms can be controlled independently, so that each support mechanism can selectively perform clamping or releasing actions.

[0016] With the above-described structure, during use, the two ends of the steel component are first inserted into the two sets of outer support guide rail groups 6 and the two sets of inner support guide rail groups 7, respectively, so that the steel component is placed on the lower clamping plates 13 of the outer support guide rail groups 6 and the inner support guide rail groups 7. Then, the bidirectional threaded rod 10 corresponding to the outer support guide rail group 6 is driven to rotate by the drive mechanism, so that the upper clamping plate 12 and the lower clamping plate 13 of the outer support guide rail group 6 are brought closer together. When the upper clamping plate 12 and the lower clamping plate 13 of the outer support guide rail group 6 are close to each other, the steel component can be clamped and the steel component can be lifted by the lower clamping plate 13, so that the upper and lower surfaces of the steel component do not contact the upper clamping plate 12 and the lower clamping plate 13 of the inner support guide rail group 7.

[0017] Then, the existing electric hoist on the galvanizing tank transfers the support plate 9 into the galvanizing tank for galvanizing. After a period of time, the corresponding drive mechanism of the inner support guide rail group 7 is activated, driving the bidirectional threaded rod 10 inside the inner support guide rail group 7 to rotate, causing the upper clamping plate 12 and lower clamping plate 13 of the inner support guide rail group 7 to approach each other and clamp the steel component. Then, the servo motor 2 corresponding to the outer support guide rail group 6 is activated again, causing the upper clamping plate 12 and lower clamping plate 13 of the outer support guide rail group 6 to separate, releasing the clamping of the steel component. At this time, the steel component is only clamped by the inner support guide rail group 7, and the part of the steel component that was originally in contact with the outer support guide rail group 6 is exposed, allowing it to fully contact the zinc liquid in the subsequent hot-dip galvanizing process, thus solving the problem of the galvanizing blind spot in this area. During the hot-dip galvanizing process, the clamping states of the outer support guide rail group 6 and the inner support guide rail group 7 can be switched again as needed, so that all parts of the steel component can be fully galvanized.

[0018] In this embodiment, the driving mechanism includes a servo motor 2 fixed on the bearing plate 9. The model can be 110ST-M04030. The output shaft of the servo motor 2 is connected to the bidirectional threaded rod 10 through a coupling. The forward and reverse rotation of the servo motor 2 can drive the bidirectional threaded rod 10 to rotate in both directions, thereby realizing the relative approach or distance between the upper clamping plate 12 and the lower clamping plate 13.

[0019] Two hanging ears 8 are fixed on both sides of the upper end of the bearing plate 9. The two hanging ears 8 are fixedly connected to steel wire ropes 1. The other end of the steel wire ropes 1 is connected to the existing lifting equipment on the hot-dip galvanizing tank. The entire device and the clamped steel components can be lifted into or out of the hot-dip galvanizing tank by the lifting equipment.

[0020] Example 2

[0021] Example 2 has a structure that is largely the same as Example 1, except that, based on Example 1, the upper clamping plate 12 is provided with screws 11 along its length. Specifically, there are at least two screws 11. The screws 11 are threadedly connected to the upper clamping plate 12, and the lower end of the screws 11 is fixed with a clamping plate 14 for pressing the steel components onto the surface of the lower clamping plate 13. It is understood that the steel components have different thicknesses, and it may not be possible to clamp all the steel components simultaneously by simply bringing the upper clamping plate 12 and the lower clamping plate 13 close to each other. By setting the screws 11, the position of the clamping plate 14 can be adjusted by rotating the screws 11 before using the lifting device. In this way, during use, the steel components can be placed under the corresponding clamping plate 14 according to their thickness. When the upper clamping plate 12 and the lower clamping plate 13 are close to each other, the corresponding steel components can be pressed by the clamping plate 14.

[0022] This utility model aims to provide a multi-directional hanging device for hot-dip galvanizing tanks. By setting independently controllable outer support guide rail group 6 and inner support guide rail group 7, and cooperating with the upper clamping plate 12 and lower clamping plate 13 driven by bidirectional threaded rod 10, selective switching of the clamping state of steel components can be achieved, thereby reducing the galvanizing blind zone caused by contact of the lifting device. At the same time, with the help of adjustable screw 11 and pressure plate 14, the adaptability and clamping stability of steel components of different specifications are improved, so as to solve the problems of galvanizing blind zone and insufficient adaptability of existing lifting devices.

[0023] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
