Description

Technical Field

[0001] This utility model relates to the field of guardrail processing technology, specifically a galvanizing device for a guardrail with a center-partition opening. Background Technology

[0002] The primary function of median strip opening guardrails (movable median strip guardrails) is to ensure emergency passage, specifically including: emergency evacuation, allowing vehicles to make emergency U-turns or evacuate in the event of traffic accidents, natural disasters, or other emergencies, ensuring the rapid passage of rescue vehicles. In daily use, they are used for two-way traffic separation to prevent vehicles from illegally making U-turns or crossing the median strip, ensuring driving safety.

[0003] To improve the service life of guardrails, hot-dip galvanizing is performed after the guardrail panels are formed. During the galvanizing process, zinc ash and dross will accumulate on the surface of the hot-dip galvanizing bath with each galvanizing cycle. Workers need to periodically remove these by hand with a scraper to prevent them from adhering to the guardrail panels and affecting the galvanizing quality. However, manual removal requires workers to stand at the edge of the galvanizing bath, which poses a certain degree of danger. Therefore, a galvanizing device for guardrails with median strip openings needs to be designed to improve the above problems. Utility Model Content

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] In the following description, embodiments of the galvanized device for the median strip opening guardrail of this utility model will be described with reference to the accompanying drawings.

[0030] Figure 1-4 This invention illustrates a galvanizing device for a median strip opening guardrail according to an embodiment of the present invention, comprising:

[0031] A zinc bath 2 is installed on the ground 1. Side plates 3 are fixedly installed on both sides of the zinc bath 2. A skimming assembly is installed between the two side plates 3. The skimming assembly slides on top of the zinc bath 2, driving the floating zinc dross in the zinc bath 2 to one side for centralized collection. Specifically, the skimming assembly includes a mounting plate 41 that slides between the two side plates 3. A lifting plate 42 is slidably connected to the bottom of the mounting plate 41. A guide post 421 is welded to the top of the lifting plate 42, and the mounting plate 41 slides on the surface of the guide post 421. A cylinder 423 is fixedly installed on the top of the mounting plate 41. The output of the cylinder 423... The end extends to the bottom of the mounting plate 41 and is fixedly connected to the lifting plate 42. An anti-detachment plate 422 is welded to the top of the guide column 421. A slag-removing assembly 43 is rotatably connected to the bottom of the lifting plate 42. Specifically, a motor 44 is fixedly installed on the top of the lifting plate 42. The slag-removing assembly 43 consists of a rotating shaft 431 and multiple arc-shaped slag-removing plates 432. The arc-shaped slag-removing plates 432 are fixedly installed on the surface of the rotating shaft 431. Through the setting of the slag-removing assembly 43, when skimming zinc ash and zinc slag, rotating the slag-removing assembly 43 drives the arc-shaped slag-removing plates 432 to drive the suspended zinc ash and zinc slag in the zinc liquid tank 2 one by one to the rear side of the zinc liquid tank 2, which can simulate manual skimming. The slag removal process improves the skimming effect of zinc ash and zinc slag. The arc-shaped design of the arc-shaped slag-removing plate 432 reduces the resistance to its rotation. The motor 44 and the rotating shaft 431 are connected via chain drive. Specifically, a main slider 45 and a secondary slider 46 are welded to the left and right sides of the mounting plate 41, respectively. The main slider 45 and the secondary slider 46 slide on the surfaces of the two side plates 3. Multiple rollers 461 are installed inside the cavities of both the main slider 45 and the secondary slider 46. The rollers 461 roll on the surfaces of the side plates 3. Through the arrangement of the rollers 461, when the main slider 45 and the secondary slider 46 slide on the surfaces of the side plates 3, the rollers 461 will... Rolling on the surface of the side plate 3 reduces the sliding resistance between the main slider 45 and the auxiliary slider 46 and the side plate 3. Welding plates 462 are welded on both the left and right sides of the mounting plate 41. The opposite sides of the welding plates 462 are welded to the surfaces of the main slider 45 and the auxiliary slider 46, respectively. Specifically, protective plates 47 are fixedly installed on both the front and rear sides of the lifting plate 42. The protective plates 47 can protect the components in the skimming assembly and prevent the zinc liquid tank 2 from spraying liquid during use, which would affect the normal use of its components. Since the temperature at the top of the zinc liquid tank 2 is high, the motors, cylinders and other equipment used in this application are all high-temperature resistant equipment.

[0032] Specifically, limit plates 31 are provided on both the front and rear sides of the side plate 3;

[0033] Specifically, a threaded rod 5 is rotatably connected to the top of ground 1, and the main slider 45 is threadedly connected to the surface of the threaded rod 5;

[0034] Specifically, a receiving trough 6 is provided on the rear side of the zinc liquid tank 2, and the receiving trough 6 is detachably installed in the inner cavity of the ground 1.

[0035] During the galvanizing of the guardrail panels, clamps are used to move the guardrail panels through the immersion and evacuation processes. Since this is not within the scope of this application, it is not described here; existing technologies can be referenced. As the galvanizing process progresses, the amount of zinc dross and ash suspended in the zinc bath 2 gradually increases. When the zinc dross and ash affect the galvanizing of the guardrail panels, the skimming component can be activated to collect them at the rear of the zinc bath 2. Because the zinc dross and ash have poor fluidity, they do not affect the normal galvanizing operation of the guardrail panels. Generally, the zinc dross and ash are removed every 7-10 days to clean the suspended zinc dross and ash, preventing insufficient zinc liquid thickness in the zinc bath 2 and ensuring a good galvanizing effect.

[0036] Working principle: When using this utility model, the user controls the cylinder 423 to drive the lifting plate 42 to slide downwards from the top of the zinc bath 2. At this time, the mounting plate 41 will slide on the surface of the guide column 421 until the bottom of the arc-shaped slag-removing plate 432 contacts the zinc liquid in the zinc bath 2. Then, the motor 44 is started, driving the rotating shaft 431 and the arc-shaped slag-removing plate 432 to rotate synchronously. At this time, the arc-shaped slag-removing plate 432 will push the suspended zinc slag and zinc dust in the zinc bath 2 to the rear. At the same time, rotating the threaded rod 5 will drive the slag-skimming assembly to slide backwards, thereby driving the main slider 45 and the auxiliary slider 45 to slide backwards. Block 46 slides on the surface of side plate 3. At this time, the slag-removing assembly 43 will slide backward while rotating, thereby driving the zinc slag and zinc dust suspended on the surface of zinc liquid pool 2 to the rear of the inner cavity of zinc liquid pool 2 for centralized collection. When hot-dip galvanizing the guardrail, it can prevent zinc slag and zinc dust from adhering to the surface of the guardrail, thus improving the quality of hot-dip galvanizing of the guardrail. Finally, rotate the threaded rod 5 to make the slag-skimming assembly stop at the top of the receiving trough 6 and collect the zinc liquid dripping from the slag-removing assembly 43 to avoid waste. The entire skimming process requires workers to coordinate, control and operate.

[0037] In summary, this galvanizing device for the median strip opening guardrail uses a skimming component to drive the zinc slag and zinc ash floating in the zinc bath 2 to the rear side of the inner cavity of the zinc bath 2 for centralized collection. When hot-dip galvanizing the guardrail panels, it can prevent zinc slag and zinc ash from adhering to the surface of the guardrail panels, thereby improving the quality of hot-dip galvanizing of the guardrail panels.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
