Description

Technical Field

[0001] This utility model relates to the technical field of traffic guardrail production equipment, specifically a pickling device for traffic guardrail production. Background Technology

[0002] In the production of traffic guardrails, the pickling process is crucial for ensuring the surface quality and corrosion resistance of the guardrails. Existing traffic guardrail pickling equipment mostly uses simple immersion pickling, which suffers from low pickling efficiency and incomplete impurity removal. Due to the lack of effective auxiliary cleaning methods, stubborn rust and oil stains are difficult to remove completely, affecting the adhesion of subsequent coatings. Furthermore, impurities generated during pickling easily circulate within the tank, not only contaminating the acid solution but also potentially causing secondary pollution and uneven pickling on the guardrail surface. In addition, some equipment has unreasonable structural design, poor equipment stability, and inconvenient maintenance, failing to meet the demands of efficient and high-quality production. Therefore, improvements to existing pickling equipment are urgently needed.

[0003] A search revealed Chinese patent publication number CN222205461U, which discloses a pickling device for guardrail panels. The device includes a mounting box with symmetrically arranged mounting side plates inside. A lower connecting mesh plate is rotatably connected to the lower ends of the two mounting side plates. An upper connecting arc plate is fixedly connected to the top of the lower connecting mesh plate and is located outside the mounting box. The upper connecting arc plate is rotatably connected to the mounting side plates. A mounting shaft is fixedly connected to the center of the two mounting side plates, and the outer end of the mounting shaft is rotatably connected to the inner cavity of the mounting box. Several partitions are fixedly connected between adjacent mounting side plates. This device avoids insufficient pickling treatment in areas where guardrail panels fold and obstruct each other, while maintaining a good ratio of pickling solution in the pickling chamber assembly and providing a good pickling effect for the guardrail panels during the pickling process.

[0004] However, this device mainly relies on pickling solution immersion to remove rust. However, there are often stubborn areas of rust on the surface of the guardrail, such as dents and areas with thicker rust. Pickling solution can only dissolve the rust through chemical reaction and cannot fully reach these areas, resulting in slow rust removal speed and poor effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an acid washing device for the production of traffic guardrails, which solves the problems of existing devices lacking efficient removal of rust and oil stains from the guardrail surface and automatic separation and collection of acid washing impurities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pickling device for producing traffic guardrails, comprising a housing, a rotating device, and a clamping device. The rotating device is located on one side of the housing, and the clamping device is located on the other side of the housing. The rotating device is equipped with a rotating motor, which is fixedly connected to the outer wall of the housing. The output shaft of the rotating motor is fixedly connected to the rotation center of a first turntable. The clamping device is equipped with a hydraulic cylinder, which has a telescopic rod. One end of the telescopic rod is connected to a ball bearing, and one side of the outer wall of the ball bearing is fixedly connected to a second turntable.

[0007] Preferably, both the first turntable and the second turntable are provided with a plurality of horizontal bars arranged in a circular array, and the horizontal bars are connected to the first turntable and the second turntable respectively through bearings.

[0008] Preferably, the housing is provided with a mounting frame, the upper outer wall of the mounting frame is fixedly connected with a baffle, one end of the baffle is provided with a mounting block, the mounting block is fixedly connected with a mounting rod, and the outer wall of the mounting rod is fixedly connected with a brush cylinder.

[0009] Preferably, the mounting frame is provided with a collection groove, and a collection net is provided on one side of the collection groove.

[0010] Preferably, the lower end of the housing is provided with a drain outlet, and the lower end of the drain outlet is provided with a cover.

[0011] Preferably, a plurality of brackets are fixedly connected to the lower outer wall of the housing, and a base is fixedly connected to the lower end of each bracket.

[0012] This utility model provides an acid pickling device for the production of traffic guardrails. It has the following beneficial effects:

[0013] This is a pickling device for traffic guardrail production. During use, a brush cylinder is installed to rub the surface of the guardrail as it rotates. The relative movement between the brush cylinder and the guardrail surface effectively breaks down stubborn rust and scrapes off oil stains, compensating for the shortcomings of simple pickling. This allows the pickling solution to more easily contact and react with the metal surface, significantly enhancing the rust and dirt removal effect. Simultaneously, with the brush cylinder fixed, the crossbars of the guardrail, connected by bearings, can rotate under friction, ensuring that the outer surface of the guardrail receives comprehensive, thorough cleaning, greatly improving the surface treatment quality.

[0014] This pickling device for traffic guardrail production utilizes a unique L-shaped baffle design to directly intercept impurities scraped off by the brush cylinder. The baffle alters the trajectory of the impurities, guiding them to the area above the collection net within the box, preventing them from floating around inside the box or re-adhering to the guardrail surface. After shutdown, the impurities naturally settle along the lower outer wall of the baffle under gravity, eventually entering the collection tank through the collection net. This achieves automatic separation and efficient collection of impurities, effectively ensuring a clean pickling environment and improving pickling efficiency and quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-5This utility model provides a pickling device for traffic guardrail production, including a housing 1, a rotating device 2, and a clamping device 3. The rotating device 2 is located on one side of the housing 1, and the clamping device 3 is located on the other side of the housing 1. The rotating device 2 is equipped with a rotating motor 10, which is fixedly connected to the outer wall of the housing 1. The output shaft of the rotating motor 10 is fixedly connected to the rotation center of the first turntable 11. The clamping device 3 is equipped with a hydraulic cylinder 15, which is equipped with a telescopic rod 14. One end of the telescopic rod 14 is connected to a ball bearing, and one side of the outer wall of the ball bearing is fixedly connected to a second turntable 13. The rotating motor 10 drives the first turntable 11 to rotate, thereby causing the clamped guardrail to rotate. This allows all surfaces of the guardrail to contact the acid solution evenly during the pickling process, effectively avoiding pickling blind spots and greatly improving the quality and effect of pickling. The hydraulic cylinder 15 adjusts the position of the second turntable 13 by adjusting the telescopic rod 14, thereby adapting to guardrails of different lengths and specifications.

[0025] Example 2

[0026] Please see Figure 1-5 In this embodiment, both the first turntable 11 and the second turntable 13 are provided with a plurality of horizontal bars 12 arranged in a circular array. The horizontal bars 12 are connected to the first turntable 11 and the second turntable 13 respectively through bearings. The connection between the horizontal bars 12 and the turntable through the bearings allows the horizontal bars 12 to rotate freely independently of the turntable. When the guardrail comes into contact with the brush cylinder 16, the horizontal bars 12 and the guardrail rotate together under the action of friction. At the same time, the brush cylinder 16 can clean the outer surface of the guardrail in an all-round and thorough manner, which greatly improves the cleaning effect.

[0027] The housing 1 contains a mounting bracket 7. A baffle 6 is fixedly connected to the upper outer wall of the mounting bracket 7. A mounting block 18 is provided at one end of the baffle 6. The mounting block 18 is fixedly connected to the mounting rod 17. A brush cylinder 16 is fixedly connected to the outer wall of the mounting rod 17. The baffle 6 adopts an L-shaped structure design, which can change the flow path of the acid in the housing 1, thereby creating a swirling effect. The swirling effect can better suspend impurities in the acid, facilitating subsequent collection and treatment. When the acid hits the vertical part of the L-shaped baffle 6, it will flow along the horizontal part, thus having a guiding function.

[0028] The mounting frame 7 is equipped with a collection tank 8, and a collection net 9 is provided on one side of the collection tank 8. After the machine stops, due to the obstruction of the baffle 6, the flow rate of the acid in the box 1 gradually slows down, and the impurities will be deposited downwards under the action of gravity. The collection net 9 is located at the lower end of the baffle 6 and can effectively collect these deposited impurities, thus realizing the automatic collection of impurities.

[0029] The lower end of the housing 1 is provided with a drain port 4, and the lower end of the drain port 4 is provided with a cover 5. The drain port 4 is mainly used to discharge acid liquid inside the housing 1. When performing equipment maintenance, replacing acid liquid, or cleaning the housing 1, the acid liquid can be quickly discharged from the housing 1 by opening the cover 5 of the drain port 4.

[0030] Multiple supports 19 are fixedly connected to the lower outer wall of the housing 1. A base 20 is fixedly connected to the lower end of each support 19. The base 20 has a frustum shape, with a smaller top and larger bottom, which lowers the center of gravity of the entire pickling unit, making it less prone to tilting or shaking during operation. When the guardrail rotates inside the housing 1 and the brush cylinder 16 performs friction cleaning, a certain dynamic force is generated. The lower center of gravity effectively resists the instability caused by these external forces, ensuring stable operation of the unit.

[0031] Instructions for use: When using this device, drive the rotating motor 10 of the rotating equipment 2 to align the crossbars 12 on the first turntable 11 and the second turntable 13. Align one end of the guardrail's central slot with the crossbar 12 on the first turntable 11 and insert it. Drive the hydraulic cylinder 15 to extend the telescopic rod 14, thereby inserting the crossbar 12 on the second turntable 13 into the other end of the guardrail's central slot. At this time, the guardrail is fixed between the rotating equipment 2 and the clamping equipment 3. Drive the rotating motor 10 to rotate the first turntable 11, causing the guardrail to undergo pickling inside the housing 1. When the guardrail rotates to the brush cylinder 16, the brush cylinder 16... The surface is rubbed to remove rust, oil, and other impurities from the guardrail surface, enhancing the rust and dirt removal effect. Since the brush cylinder 16 is fixed, the crossbar 12 of the guardrail is connected to the corresponding turntable through a bearing, so the friction can drive the guardrail to rotate, thereby thoroughly cleaning the outer surface of the guardrail. The impurities wiped off float due to the swirling effect inside the box 1 and are eventually blocked by the L-shaped baffle 6, preventing the impurities from floating around inside the box 1 or re-attaching to the guardrail surface. After the machine stops, the impurities on the lower outer wall of the baffle 6 settle downwards and eventually enter the collection tank 8 through the collection net 9, making the cleaning work more convenient and efficient.
