A hot-dip galvanizing fixture for steel tower components

Abstract

This utility model relates to the field of hot-dip galvanizing technology and provides a hot-dip galvanizing fixture for steel tower components. The fixture includes a box, a support frame installed inside the box, a liquid storage tank installed inside the box, a lifting mechanism fixedly connected to the outside of the support frame, a hanging basket fixedly connected to the outside of the lifting mechanism, a swaying device fixedly connected inside the support frame, and a swinging device outside the hanging basket. In this utility model, the extrusion column applies extrusive force to the moving plates during rotation, causing the two moving plates to move towards each other. As the moving plates move, they drive the slider to slide along the sliding plate, thereby causing the push plate to apply a slight pushing force to the hanging basket. Subsequently, under the elastic force of the return spring, the two moving plates reset, the push plate disengages from the hanging basket, and the hanging basket returns to its original position. Through this reciprocating action, the hanging basket can be periodically micro-moved during the galvanizing process, avoiding blind spots in the coating at the contact point between the hanging basket and the workpiece, thereby improving the integrity and consistency of the galvanized coating.

Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing technology, and in particular relates to a hot-dip galvanizing tooling for steel tower components. Background Technology

[0002] Hot-dip galvanizing of steel tower components is an extremely efficient and long-lasting metal corrosion protection process. Its core involves immersing steel components, which have undergone rigorous pretreatment (such as pickling and rust removal, and fluxing), into molten zinc at approximately 450°C. Through a series of complex physicochemical reactions, a dense and robust zinc-iron alloy layer and a pure zinc layer are formed on the surface of the steel substrate. This galvanized layer not only acts as a physical barrier to prevent the steel components from contacting moisture and corrosive media in the atmosphere, but also provides excellent electrochemical protection (cathode protection). Even if there is slight damage to the coating, zinc will preferentially corrode, thus protecting the internal steel from corrosion. Steel tower components treated with this process exhibit a qualitative leap in weather resistance and corrosion resistance, ensuring a service life of decades even in harsh outdoor environments. This significantly reduces maintenance costs and is an indispensable key corrosion protection technology for infrastructure such as power transmission towers and communication towers.

[0003] Currently, in the process of hot-dip galvanizing steel components of iron towers, the steel components are usually placed in a hanging basket and then immersed in molten zinc by a lifting mechanism. In the existing technology, the hanging basket is mostly stationary or in a single lifting state during the immersion and lifting process. There are local contact points between the hanging basket and the surface of the workpiece, which can easily form galvanizing blind spots, resulting in uneven coating. Utility Model Content

[0004] This utility model provides a hot-dip galvanizing fixture for steel tower components, which aims to solve the problem that in the prior art, the hanging basket is mostly in a static or single lifting state during the galvanizing and lifting process, which is prone to two problems: First, there are local contact points between the hanging basket and the workpiece surface, which can easily form galvanizing blind spots, resulting in uneven coating.

[0005] This utility model is implemented as follows: a hot-dip galvanizing fixture for steel tower components includes: a box body, a support frame installed inside the box body, a liquid storage tank installed inside the box body, a lifting mechanism fixedly connected to the outside of the support frame, a hanging basket fixedly connected to the outside of the lifting mechanism, a swaying device fixedly connected inside the support frame, and a swinging device provided outside the hanging basket. The shaking device includes a fixed plate and two movable plates. A drive motor is installed inside the fixed plate, and a rotating plate is installed at the output end of the drive motor. Extrusion columns are symmetrically installed on the lower surface of the rotating plate. A slider is fixedly connected to the lower part of the two movable plates, and a sliding plate is slidably connected inside the slider. The sliding plate is fixedly connected to the support frame. Two connecting blocks are fixedly connected to each of the two movable plates. The same telescopic rod is fixedly connected inside the two corresponding connecting blocks. A return spring is sleeved on the telescopic rod. A push plate is fixedly connected to the outside of the movable plates.

[0006] Preferably, the fixing plate is fixedly connected to the housing, and the pull-back spring is fixedly connected to the two connecting blocks.

[0007] Preferably, a pusher block is installed outside the pusher plate, and the pusher block overlaps the outside of the hanging basket.

[0008] Preferably, the swing device includes two locking blocks and a buffer pad. The two locking blocks are symmetrically installed on the front of the lifting mechanism. The same fixing rod is fixedly connected inside the two locking blocks, and a collar is provided on the outer sleeve of the fixing rod.

[0009] Preferably, a drive plate is fixedly connected to the outside of the collar, and the drive plate is fixedly connected above the hanging basket.

[0010] Preferably, the collar and the fixing rod form a rotatable connection.

[0011] Preferably, the buffer pad is fixedly connected inside the lifting mechanism, and the hanging basket overlaps the outside of the buffer pad.

[0012] Compared with related technologies, the hot-dip galvanizing fixture for steel tower components provided by this utility model has the following beneficial effects: 1. In this utility model, by starting the drive motor, the drive motor drives the rotating plate to rotate, and the rotating plate further drives the extrusion column to rotate. During the rotation, the extrusion column applies extrusion force to the moving plate, causing the two moving plates to move towards each other. When the moving plate moves, it drives the slider to slide along the slide plate, thereby driving the push plate to apply a slight pushing force to the hanging basket. Subsequently, under the elastic force of the return spring, the two moving plates reset, the push plate disengages from the hanging basket, and the hanging basket returns to its original position. Through this reciprocating action, the hanging basket can be periodically micro-moved during the galvanizing process, avoiding the appearance of coating blind spots at the contact points between the hanging basket and the workpiece, thereby improving the integrity and consistency of the galvanizing coverage.

[0013] 2. In this utility model, the push plate applies force to the hanging basket, causing it to move. During the movement, the hanging basket drives the drive plate and collar to rotate outside the fixed rod, thereby realizing the swing of the hanging basket. When the push plate moves away from the hanging basket, the hanging basket returns to its original position by its own weight. During the return process, pressure is applied to the buffer pad, which plays a shock-absorbing role, avoiding the impact caused by the hanging basket returning to its original position too quickly. Through this action, not only can the workpiece obtain a more uniform coverage effect in the zinc liquid, but the problem of zinc liquid splashing caused by the rapid return of the hanging basket can also be effectively avoided, thus improving the safety of the galvanizing process and the coating quality.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a hot-dip galvanizing fixture for steel tower components, such as... Figure 1-5 As shown, it includes a box body 1, a support frame 2 installed inside the box body 1, a liquid storage tank 3 installed inside the box body 1, a lifting mechanism 4 fixedly connected to the outside of the support frame 2, a hanging basket 5 fixedly connected to the outside of the lifting mechanism 4, a shaking device 6 fixedly connected inside the support frame 2, and a swinging device 7 provided outside the hanging basket 5. The shaking device 6 includes a fixed plate 601 and two movable plates 605. A drive motor 602 is installed inside the fixed plate 601. A rotating plate 603 is installed at the output end of the drive motor 602. Extrusion columns 604 are symmetrically installed on the lower surface of the rotating plate 603. A slider 607 is fixedly connected to the two movable plates 605. A slide plate 606 is slidably connected inside the slider 607. The slide plate 606 is fixedly connected inside the support frame 2. Two connecting blocks 608 are fixedly connected to each of the two movable plates 605. The same telescopic rod 609 is fixedly connected inside the two corresponding connecting blocks 608. A return spring 610 is sleeved on the telescopic rod 609. A push plate 611 is fixedly connected to the outside of the movable plates 605.

[0018] In this embodiment, when the rotating plate 603 rotates under the drive of the motor, it will drive the pressing column 604 fixed on the lower surface to rotate synchronously. During the rotation, the pressing column 604 continuously applies pressing force to the moving plate 605, thereby achieving a continuous and stable pushing effect. Through this cooperation, the movement of the moving plate 605 can be more uniform, and there will be no sudden impact force, which is conducive to the smooth micro-movement of the hanging basket 5.

[0019] In a further preferred embodiment of this utility model, the fixing plate 601 is fixedly connected inside the box 1, the pull spring 610 is fixedly connected inside the two connecting blocks 608, and a push block is installed outside the push plate 611, and the push block overlaps outside the hanging basket 5.

[0020] In this embodiment, a return spring 610 is provided on the outer sleeve of the telescopic rod 609. After the telescopic rod 609 is stretched, the return spring 610 provides a restoring force, so that the moving plate 605 can quickly return to its original position when the external force is lost. Through this cooperation, a cyclic micro-motion thrust can be realized to form a controllable reciprocating motion, thereby ensuring continuous fine adjustment during the galvanizing process.

[0021] In a further preferred embodiment of this utility model, the swing device 7 includes two locking blocks 701 and a buffer pad 705. The two locking blocks 701 are symmetrically installed on the front of the lifting mechanism 4. The same fixing rod 702 is fixedly connected inside the two locking blocks 701. A collar 703 is provided outside the fixing rod 702. A drive plate 704 is fixedly connected outside the collar 703. The drive plate 704 is fixedly connected above the hanging basket 5. The collar 703 and the fixing rod 702 form a rotatable connection. The buffer pad 705 is fixedly connected inside the lifting mechanism 4, and the hanging basket 5 overlaps the buffer pad 705.

[0022] In this embodiment, the hanging basket 5 will overlap the buffer pad 705 during the reset process. The buffer pad 705 will buffer the hanging basket 5 and avoid the impact force generated by direct impact. Through this cooperation, the structural strength of the hanging basket 5 and the lifting mechanism 4 can be protected, and the problem of zinc liquid splashing due to excessive vibration can be avoided.

[0023] In summary, by activating the drive motor 602, the drive motor 602 drives the rotating plate 603 to rotate. The rotating plate 603 further drives the extrusion column 604 to rotate. During the rotation, the extrusion column 604 applies extrusion force to the moving plate 605, causing the two moving plates 605 to move towards each other. When the moving plates 605 move, they drive the slider 607 to slide along the slide plate 606, thereby causing the push plate 611 to apply a slight pushing force to the hanging basket 5. Subsequently, under the elastic force of the return spring 610, the two moving plates 605 return to their original position, and the push plate 611 disengages from the hanging basket 5, thus... The hanging basket 5 returns to its original position. Through this reciprocating motion, the hanging basket 5 can be periodically micro-moved during the galvanizing process. The force applied to the hanging basket 5 by the push plate 611 causes the hanging basket 5 to move. During the movement, the hanging basket 5 drives the drive plate 704 and the collar 703 to rotate outside the fixed rod 702, thereby realizing the swing of the hanging basket 5. When the push plate 611 moves away from the hanging basket 5, the hanging basket 5 returns to its original position by its own weight. During the return process, pressure is applied to the buffer pad 705, which plays a shock absorption role and avoids the impact caused by the hanging basket 5 returning to its original position too quickly.
