Description

Technical Field

[0001] This utility model belongs to the field of protective plate production equipment, and in particular relates to a galvanizing device for highway guardrails. Background Technology

[0002] As a key safety facility on highways, highway guardrails need to withstand the erosion of extreme natural environments for a long time. In order to resist these environmental erosions and ensure the service life of the guardrails, hot-dip galvanizing is used to achieve double corrosion protection for highway guardrails.

[0003] The existing hot-dip galvanizing method for highway guardrails mainly involves lifting both ends of the guardrail with a gantry crane, placing it into a galvanizing tank, and then removing the guardrail after a period of galvanizing to complete the galvanizing process.

[0004] In actual use, a layer of scum will be generated on the surface of the zinc liquid. This scum is mainly composed of complex substances generated by the reaction of zinc liquid with the external environment and the steel surface. In order to avoid these scum adhering to the surface of the highway guardrail, after the highway guardrail is completely immersed in the zinc liquid during the galvanizing process, the workers will scoop out the scum.

[0005] However, the galvanizing process is hot-dip galvanizing, which generates a large amount of water mist and fumes, affecting the visibility of workers. At the same time, the heat in the galvanizing tank poses certain safety hazards. Utility Model Content

[0006] This utility model addresses the technical problems existing in the current galvanizing process of highway guardrails by proposing a reasonably designed, simple, and easy-to-process device for galvanizing highway guardrails that can reduce the involvement of workers and avoid safety hazards.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a galvanizing device for highway guardrails, including a galvanizing tank installed below ground level. Smoke extraction boxes are installed on both sides of the top of the galvanizing tank. A protective plate is installed on the top of the smoke extraction box, with the protective plate positioned on the side of the smoke extraction box closest to the galvanizing tank. A movable seat is installed on the side of the protective plate closest to the galvanizing tank, and the movable seat slides along the long side of the protective plate. An electric cylinder is installed on the movable seat, with its power end vertically positioned and connected to a connecting rod. A retrieval trough is connected to the end of the connecting rod away from the electric cylinder. The retrieval trough can extend into the galvanizing tank. Drainage holes are provided on the side wall of the retrieval trough away from the opening, and the drainage holes are evenly distributed on the side wall of the retrieval trough, with intervals between two retrieval troughs. The moving length of the movable seat is greater than the length of the galvanizing tank.

[0008] Preferably, the movable seat is slidably mounted on the protective plate via a drive mechanism. The drive mechanism includes synchronous pulleys located near both ends of the protective plate, with a synchronous belt fitted between the synchronous pulleys. Both ends of the synchronous belt are fixed to the movable seat. The protective plate is provided with a guide rail, and the movable seat is provided with a slider that cooperates with the guide rail. Any one of the synchronous pulleys is connected to a drive motor.

[0009] Preferably, the smoke extraction box includes a rectangular box body with an opening on the side of the extraction box body closest to the galvanizing tank and a suction pipe connected to the side of the extraction box body away from the galvanizing tank. A partition is provided inside the extraction box body, and the partition is spaced apart along the long side of the protective plate.

[0010] Preferably, the partition is provided with constricted inclined plates on both sides, and the constricted inclined plates between the two partitions are symmetrically spaced.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides a galvanizing device for highway guardrails. By setting up a fume extraction box, the device effectively extracts the fumes generated during the galvanizing process, avoiding visual interference and improving the service life of related components. At the same time, the protective plate not only serves as a fixing frame for the drive mechanism but also provides a certain degree of protection for personnel during maintenance. Finally, the dredging trough allows for the removal of floating slag, reducing labor intensity and avoiding safety hazards. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figures 1-3 As shown, this embodiment aims to solve the safety hazards in the galvanizing process of the highway guardrail 3. To this end, the galvanizing device for the highway guardrail 3 provided in this embodiment includes a galvanizing tank 1 set below the ground. The existing galvanizing tank 1 is generally set with its top surface flush with the ground, which is a mature existing technology. Therefore, it will not be described in detail in this embodiment.

[0017] Considering the issue of fumes, in this embodiment, fume extraction boxes 2 are provided on both sides of the top of the galvanizing tank 1. The fume extraction box 2 includes a flat rectangular box body 21, which consists of a bottom plate, a top plate, and end plates at the front and rear. The purpose of this arrangement is mainly to facilitate the movement of workers when extracting fumes, because other unforeseen things may be discovered during the galvanizing process. Therefore, it is necessary to expose the passage for workers to walk, and the flat design facilitates movement.

[0018] Meanwhile, the side of the suction box body 21 closest to the galvanizing tank 1 is set with an opening, while the side of the suction box body 21 away from the galvanizing tank 1 is connected to a suction pipe 22, which is connected to an exhaust fan to achieve exhaust.

[0019] To ensure the stability of workers walking, partitions 23 are installed inside the suction box body 21, with the partitions 23 spaced apart along the long side of the galvanizing tank 1. This design of the smoke suction box 2 not only ensures rapid smoke extraction but also prevents the smoke from rising and reducing the lifespan of some equipment.

[0020] In order to protect the staff and facilitate the safe automatic slag removal equipment, in this embodiment, a protective plate 3 is provided on the top of the flue gas extraction box 2. The protective plate 3 is located on the side of the flue gas extraction box 2 near the galvanizing tank 1, and the protective plate 3 is a vertically arranged metal plate.

[0021] In order to achieve automatic slag removal, in this embodiment, a movable seat 4 is provided on the side of the protective plate 3 near the galvanizing tank 1. The movable seat 4 is L-shaped in general, and the vertical part is used to install the slider. A guide rail that cooperates with the slider is provided on the protective plate 3. In this way, under the action of power, it can slide along the long side of the protective plate 3.

[0022] Considering that the slag removal process requires partial immersion in the molten zinc, and that the slag removal process needs to be far from the liquid surface, an electric cylinder 41 is installed on the movable base 4. The power end of the electric cylinder 41 is vertically arranged and connected to a connecting rod 42. The connecting rod 42 is inverted L-shaped, and its horizontal end is used to connect to the power end of the electric cylinder 41. A retrieval trough 5 is connected to the end of the connecting rod 42 away from the electric cylinder 41. The retrieval trough 5 is rectangular, and its opening face is its front face. Thus, under the action of the electric cylinder 41, the retrieval trough 5 can be inserted into the galvanizing tank 1 or extended out of the galvanizing tank 1.

[0023] Considering that a large amount of molten zinc will enter during the retrieval process, a leakage hole 51 is provided on the side wall of the retrieval tank 5 away from the tank opening. The leakage hole 51 is evenly distributed on the side wall of the retrieval tank 5, so that the molten zinc will leak out directly, while the scum will remain in the retrieval tank 5.

[0024] Because the lifting cables of the galvanized sheet extend out when it is submerged in the galvanizing tank 1, the retrieval process needs to avoid the cables. Therefore, the two retrieval tanks 5 are spaced apart. Of course, the moving length of the movable seat 4 is greater than the length of the galvanizing tank 1. This ensures that the retrieval tanks 5 can be easily cleaned of scum. In this embodiment, the scum is cleaned manually by hooking it out with an iron hook.

[0025] With the above setup, after the protective plate 3 is fully submerged in the molten zinc, the retrieval tank 5 begins operation to remove the scum. After one end of the protective plate 3 is raised (to avoid carrying molten zinc onto the protective plate 3, one end of the protective plate 3 is raised slowly first, forming a certain angle, before the other end is pulled up), the scum that could not be retrieved from the middle (two retrieval sections) after being raised is retrieved and moved to the other end of the galvanizing tank 1. After the galvanized plate is removed, the retrieval tank 5 rises and moves out of the galvanizing tank 1, allowing for cleaning. It should be noted that to avoid large fluctuations in the molten zinc, the moving base 4 cannot move quickly.

[0026] To drive the movable seat 4, the movable seat 4 is slidably mounted on the protective plate 3 via a drive mechanism 6. Specifically, the drive mechanism 6 includes synchronous pulleys 62 positioned near both ends of the protective plate 3, with a synchronous belt 63 fitted between the synchronous pulleys 62. Both ends of the synchronous belt 63 are fixed to the movable seat 4. The movable seat 4 is equipped with connecting blocks and pressure plates, and the two ends of the synchronous belt 63 are positioned between the connecting blocks and pressure plates, which are connected by bolts to secure the synchronous belt 63. Simultaneously, a drive motor 61 is connected to any one of the synchronous pulleys 62. To better protect the drive motor 61, it is positioned on the side of the protective plate 3 away from the galvanized sheet. It should be noted that since the drive motor 61 can impede movement, guardrails or markers are necessary to prevent accidental falls during emergency handling.

[0027] Considering the movement of the smoke extraction box 2, and for further support, constricted inclined plates 24 are provided on both sides of the partition 23, with the constricted inclined plates 24 symmetrically spaced between the two partitions 23. This creates a constricted design, which improves support while also facilitating extraction.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
