Description

Technical Field

[0001] This invention relates to the field of guardrail repair technology, and more specifically, to a high-speed guardrail repair device. Background Technology

[0002] Highway guardrails, as a core facility of the highway traffic safety protection system, are widely distributed on both sides of the roadbed, in the central median, and in dangerous sections. Their mainstream materials include corrugated steel plates, concrete, and basalt fiber composite materials, among which corrugated steel guardrails dominate in practical applications due to their excellent crashworthiness and cost-effectiveness. The protective function of highway guardrails extends throughout the entire traffic flow: when a vehicle crashes out of control, it efficiently absorbs impact energy through its own deformation, reducing the extent of vehicle damage and the risk of injury or death to drivers and passengers; simultaneously, it acts as a guide and restraint mechanism, guiding out-of-control vehicles back to the normal lane, preventing them from running off the road or entering oncoming lanes and causing chain-reaction accidents; furthermore, it effectively separates oncoming traffic flows and isolates non-motorized vehicles and pedestrians, reducing interference and conflict between different traffic participants from the source and ensuring road traffic order.

[0003] However, the high speeds and heavy traffic on highways lead to frequent rear-end collisions, rollovers, and scrapes, easily causing damage to guardrails such as deformation, breakage, tilting posts, or loosening of foundations. Damaged guardrails experience a rapid decline in their protective performance. If not repaired promptly, they not only fail to provide their original safety function but may also cause secondary accidents due to structural instability and irregular waveforms, becoming new road safety hazards. Traditional guardrail repair methods primarily rely on manual labor combined with welding machines and crowbars, which have several unavoidable drawbacks: First, highway emergency repairs require rapid progress to minimize road closure time; manual repairs are inefficient and cannot meet the timeliness requirements of emergency repairs. Second, manual correction relies on the experience of the workers, making it difficult to achieve industry standards for guardrail waveform accuracy and installation spacing, resulting in a significant reduction in protective performance after repair. Third, workers must be in close proximity to passing vehicles on the highway shoulder, facing significant traffic interference and posing substantial safety risks, seriously threatening their personal safety. Therefore, developing a high-efficiency, precise, and safe high-speed guardrail repair equipment has become an urgent need to solve the current pain points in guardrail repair. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-speed guardrail repair device, which aims to solve the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a high-speed guardrail repair device, including a mounting frame installed on a high-speed tractor, wherein a repair component is provided on one side of the mounting frame; The repair component includes a repair frame disposed on one side of the mounting frame, a plurality of first repair rollers are disposed within the repair frame, and a second repair roller is disposed on one side of each of the first repair rollers. The second repair rollers and the first repair rollers are stacked, and the guardrail passes between the first repair rollers and the second repair rollers for repair by the first repair rollers and the second repair rollers rolling against each other. The first repair roller is fitted with an adjustable first shaping cylinder on its outer side, and the second repair roller is fitted with an adjustable second shaping cylinder on its outer side. The first and second shaping cylinders are adjusted laterally on the first and second repair rollers respectively so that the first and second shaping cylinders can be adapted to the undulating guardrail. Two trimming grooves are provided on the outer side of the first shaping cylinder, and two trimming rings are fixedly provided on the outer side of the second shaping cylinder. The outer side of each trimming ring extends into the corresponding trimming groove, and the trimming ring is adapted to the protruding area of ​​the guardrail so that it extends into the trimming groove for trimming.

[0006] Optionally, in one possible implementation, a gear is provided at one end of the first repair roller and the second repair roller, and the two gears mesh with each other. A transmission rack is provided on one side of the gear to which the second repair roller belongs. The first repair roller and the second repair roller rotate by the rotation of the transmission rack and the gear. A sliding groove is provided on the outer side of the first repair roller and the second repair roller. The first shaping cylinder and the second shaping cylinder are slidably connected to the sliding groove to which the first repair roller and the second repair roller belong through a slider. Through the sliding cooperation of the slider and the sliding groove, the first repair roller and the second repair roller drive the first shaping cylinder and the second shaping cylinder to rotate, while the first shaping cylinder and the second shaping cylinder move laterally on the outer side of the first repair roller and the second repair roller respectively, in order to adapt to the undulation of the guardrail. Optionally, in one possible implementation, a protective cover is provided on the side of the mounting frame away from the repair frame, and a slag collection box is provided at one end of the protective cover. Both the protective cover and the slag collection box cover the outside of the mounting frame. A first polishing disc is provided inside the protective cover, and a position-adjustable second polishing disc is provided on one side of the repair frame. The second polishing disc is located at the bottom side of the slag collection box. The first and second polishing discs are arranged alternately. The first and second polishing discs rotate to polish the guardrail to be repaired first, in order to remove rust and impurities from the surface of the guardrail. A negative pressure fan is provided on one side of the first polishing disc. The negative pressure fan is bolted to the mounting frame. The negative pressure fan generates negative pressure when it is started to draw the impurities generated by polishing into the slag collection box. A suspension frame is provided at one end of the mounting frame. Optionally, in one possible implementation, a support frame is provided on one side of the repair frame, an application box is provided inside the support frame, a liquid storage cylinder is provided inside the application box, and an application roller is provided on the liquid storage cylinder. The application roller passes through the guardrail and the support frame, and applies anti-rust material to the guardrail. The repair frame and the support frame are respectively provided with misalignment openings. The misalignment openings are located between the first repair roller and the second repair roller, and the misalignment openings extend to one end of the repair frame and the support frame. The misalignment openings prevent interference between the repair frame and the support frame and the guardrail, allowing the guardrail to be repaired by passing through the misalignment openings.

[0007] The technical effects and advantages of this invention are as follows: By integrating polishing, rust removal, shaping, and rust prevention into a single process, and using a high-speed tractor to continuously move and advance the guardrail, manual segmented operation is eliminated, significantly reducing the repair time for a single section of guardrail. Compared to the traditional decentralized manual repair method, the integrated process reduces the gaps between procedures, effectively shortens road closure time, fully meets the timeliness requirements of emergency highway repairs, and minimizes the impact on traffic flow. This invention utilizes the stacked and rolling structure of the first and second repair rollers, combined with the laterally adjustable first and second shaping cylinders, and the concave-convex adaptation design of the trimming groove and trimming ring, to accurately correct the undulations and protrusions of the guardrail, so that the repaired guardrail waveform is restored to the standard shape and the installation spacing meets the specifications. During the repair process, the alternating first and second polishing discs of this invention achieve comprehensive rust removal across the entire guardrail surface, preventing residual rust from affecting the repair effect and ensuring that the guardrail regains its original core protective functions such as anti-collision buffering and guiding restraint. Simultaneously, after reshaping and repair, the coating roller evenly applies the rust-preventive material from the storage tank to the guardrail surface, forming a complete rust-preventive protective film that effectively isolates corrosive media such as air and moisture, slowing down the rusting and aging process. This integrated repair process not only ensures the construction quality of each stage of rust removal, reshaping, and rust prevention, but also reduces the frequency of subsequent guardrail maintenance and replacement costs, extending the overall service life of the guardrail and achieving long-term safety protection benefits.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0019] This embodiment discloses a highway guardrail repair device, which is mainly used for on-site repair of corrugated steel guardrails on highways, and is especially suitable for problems such as guardrail deformation and surface corrosion caused by vehicle collisions, scrapes and other accidents.

[0020] As attached Figure 1 and attached Figure 2As shown, the core installation base of this equipment is the mounting frame 1. A suspension frame 17 is welded to one end of the mounting frame 1 for fixing the equipment during suspension, storage, and transportation. A repair frame 2 and a support frame 18 are provided on one side of the mounting frame 1. All components are fixed by welding and bolting to form a stable integrated structure, ensuring the stability of the equipment during high-speed mobile operation.

[0021] As attached Figure 7 and attached Figure 8 As shown, a protective cover 12 is provided on the side of the mounting frame 1 away from the repair frame 2. It is slidably connected to the slide groove by a slider, and the installation position of the protective cover 12 can be adjusted according to the height of the guardrail. One end of the protective cover 12 is fixed to the slag receiving box 13 by a buckle. The protective cover 12 and the slag receiving box 13 together cover the outside of the polishing assembly to prevent rust and impurities generated during polishing from splashing and polluting the environment or affecting passing vehicles.

[0022] Inside the protective cover 12, a first polishing disc 14 is mounted via a rotating shaft, as shown in the attached diagram. Figure 7 As shown, a negative pressure fan 16 is installed on one side of the first polishing disc 14, with the air intake of the negative pressure fan 16 facing the working area of ​​the first polishing disc 14. A second polishing disc 15 is installed on one side of the repair frame 2 via an adjusting bracket. The second polishing disc 15 is located at the bottom of the slag receiving box 13, and the first polishing disc 14 and the second polishing disc 15 are staggered, with both polishing surfaces in contact with the guardrail surface. The adjusting bracket can adjust the position of the second polishing disc 15 via a threaded structure to ensure it adapts to guardrails with different degrees of deformation.

[0023] As attached Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the repair frame 2 is fixedly installed in the middle of the mounting frame 1. Several first repair rollers 3 are installed in the repair frame 2 through bearing seats. A second repair roller 4 is provided on one side of each first repair roller 3. The first repair rollers 3 and the second repair rollers 4 are stacked and parallel. The gap between them is adapted to the thickness of the corrugated steel guardrail to ensure that the guardrail can pass through smoothly and be uniformly crushed.

[0024] A first shaping cylinder 5 is sleeved on the outer side of the first repair roller 3, and a second shaping cylinder 7 is sleeved on the outer side of the second repair roller 4, as shown in the attached figure. Figure 4 and attached Figure 6 As shown, the outer sides of the first repair roller 3 and the second repair roller 4 are provided with sliding grooves 11, and the inner sides of the first shaping cylinder 5 and the second shaping cylinder 7 are provided with sliders. The sliders slide in cooperation with the sliding grooves 11, so that the first shaping cylinder 5 can move laterally on the first repair roller 3 and the second shaping cylinder 7 can move laterally on the second repair roller 4.

[0025] The outer circumferential surface of the first shaping cylinder 5 has two symmetrical trimming grooves 6, as shown in the attached figure. Figure 6As shown, two symmetrical trimming rings 8 are welded circumferentially to the outer side of the second shaping cylinder 7. The outer diameter of the trimming ring 8 matches the inner diameter of the trimming groove 6, and the outer side of each trimming ring 8 extends into the corresponding trimming groove 6, forming a concave-convex fit structure. When the guardrail passes between the first shaping cylinder 5 and the second shaping cylinder 7, the trimming ring 8 can be embedded into the protruding area of ​​the guardrail and guided into the trimming groove 6 for precise trimming, ensuring that the guardrail waveform is restored to the standard shape.

[0026] As attached Figure 4 As shown, gears 9 are keyed to the same end of the first repair roller 3 and the second repair roller 4. The two gears 9 mesh with each other. A transmission rack 10 meshes with one side of the gear 9 belonging to the second repair roller 4. The transmission rack 10 is connected to the power output device of the high-speed tractor. The power device drives the transmission rack 10 to rotate, which in turn drives the gear 9 to rotate, so as to realize the synchronous reverse rotation of the first repair roller 3 and the second repair roller 4, providing stable rolling power for the shaping of the guardrail. Example

[0027] Based on Example 1, this embodiment is illustrated in the appendix. Figure 3 As shown, a support frame 18 is welded to one side of the repair frame 2. An application box 19 is fixedly installed inside the support frame 18 by bolts. A liquid storage cylinder 22 is set inside the application box 19. The liquid storage cylinder 22 is used to store anti-rust materials such as anti-rust paint or anti-rust grease. The bottom of the liquid storage cylinder 22 is connected to the application roller 21 through a conduit. The application roller 21 is installed at the bottom of the application box 19 through a rotating shaft, and its roller surface is in contact with the surface of the guardrail.

[0028] Both the repair frame 2 and the support frame 18 have misalignment openings 20, as shown in the attached figure. Figure 7 As shown, the misalignment opening 20 is located on the extension line between the first repair roller 3 and the second repair roller 4. Its opening size is slightly larger than the width of the guardrail. The misalignment opening 20 can effectively avoid interference between the repair frame 2, the support frame 18 and the guardrail, ensuring that the guardrail can smoothly pass through each component to complete the repair work.

[0029] The specific working principle is as follows; Before operation, the mounting frame 1 is fixed on the high-speed tractor. According to the height and waveform dimensions of the guardrail to be repaired, the height is adjusted by the suspension frame 17 so that the polishing surfaces of the first polishing disc 14 and the second polishing disc 15 are in contact with the guardrail surface. The lateral position of the second polishing disc 15 is adjusted by the adjusting bracket to ensure that it overlaps with the first polishing disc 14 and covers the entire width of the guardrail. The first shaping cylinder 5 and the second shaping cylinder 7 are obstructed and move laterally on the corresponding repair rollers so that the mating position of the trimming groove 6 and the trimming ring 8 matches the standard waveform of the guardrail. Sufficient anti-rust material is added to the liquid storage cylinder 22 to ensure that the coating roller 21 can be fully wetted.

[0030] Start the high-speed tractor, for example, moving the equipment slowly along the guardrail at a speed of 5-10 km / h, while simultaneously starting the first polishing disc 14, the second polishing disc 15, and the negative pressure fan 16. The first and second polishing discs 14 and 15 rotate under the drive of an external motor, polishing and cleaning the rust, scale, and attached impurities on the guardrail surface. Because they are staggered, they achieve comprehensive polishing coverage of the guardrail surface, ensuring thorough rust removal. Rust, debris, and other impurities generated during polishing are concentrated in the work area by the protective cover 12. The negative pressure fan 16, once started, generates negative pressure, drawing these impurities through the suction port into the slag collection box 13 for collection, preventing impurities from splashing and causing safety hazards.

[0031] After polishing and rust removal, the guardrail continues to move with the equipment, passing through the misalignment opening 20 on the repair frame 2 and entering between the first repair roller 3 and the second repair roller 4. At this time, the transmission rack 10 rotates under the power of the tractor, driving the gear 9 meshing with it to rotate. Since the two gears 9 mesh with each other, the first repair roller 3 and the second repair roller 4 rotate synchronously in opposite directions, applying uniform rolling pressure to the guardrail. Furthermore, passing through the misalignment opening 20 not only facilitates the guardrail to pass through for repair, but also allows for the offsetting of the support structure at the bottom of the guardrail, enabling long-distance repair of the guardrail. Alternatively, the device can be installed on the tractor, allowing the deformed guardrail to be removed for repair.

[0032] For the uneven and deformed parts of the guardrail, the first shaping cylinder 5 and the second shaping cylinder 7 can move laterally adaptively while the repair roller rotates through the sliding cooperation of the slider and the slide groove 11, always keeping in contact with the guardrail surface; the protruding area of ​​the guardrail is embedded in the trimming groove 6 of the first shaping cylinder 5, and the trimming ring 8 on the second shaping cylinder 7 applies lateral pressure to the protruding area to trim it to the standard size, ensuring that the guardrail waveform is restored to flatness and the installation spacing meets the specifications.

[0033] After repair, the guardrail continues to pass through the misalignment opening 20 on the support frame 18 and enters the coating tank 19. The rust-preventive material in the storage cylinder 22 is continuously delivered to the coating roller 21 via a conduit. The coating roller 21 rotates under the influence of the guardrail, evenly applying the rust-preventive material to the repaired surface and the entire outer surface of the guardrail, forming a protective rust-preventive film that effectively prevents the guardrail from rusting again and extends its service life. The coated guardrail moves with the equipment to complete the entire repair process, requiring no manual intervention during the operation, achieving integrated continuous repair.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
