Description

Technical Field

[0001] This invention relates to the field of guardrail cleaning, specifically a cleaning device for road and bridge side guardrails. Background Technology

[0002] Road and bridge guardrails are constantly exposed to open environments, making them susceptible to various factors such as vehicle exhaust, road dust, mud and water splashes, and rain and snow erosion. Dust, oil, mud, and other deposits often gradually accumulate on the guardrail surface. Over time, this buildup not only affects the cleanliness of the guardrail's appearance but can also negatively impact the protective coating, reducing its corrosion resistance and thus its lifespan. Furthermore, some guardrails have reflective markings or warning coatings; if covered by dirt, their warning effect may be weakened, potentially affecting road safety. Therefore, regular cleaning of road and bridge guardrails is of significant maintenance and safety importance.

[0003] In existing cleaning methods, a combination of water rinsing and brushing or wiping is typically used to clean the surface of guardrails. However, in some equipment or operations, the water spray unit and the cleaning contact surface are often set up separately. That is, the water flow acts on the guardrail surface first or later, while the brushing component rubs and cleans the guardrail from another location. Due to the difference in spatial position or time coordination between the water flow and the cleaning action, the stains on the guardrail surface may not be sufficiently wetted or softened before being brushed, increasing cleaning resistance and affecting the stain removal effect. Alternatively, the water flow may reach the cleaning area only after brushing is completed, causing the stripped mud, sand, dust, etc., to not be washed away in time, and may still remain or re-adhere to the guardrail surface, thus affecting the overall cleaning quality.

[0004] Therefore, a road and bridge side guardrail cleaning device is provided to address the above-mentioned problems. Summary of the Invention

[0005] This invention provides a road and bridge side guardrail cleaning device to address the problem that existing guardrail cleaning processes have separate water spraying parts and cleaning contact surfaces, which makes it difficult to wet and soften stains in time and to wash away brushed-off attachments simultaneously, thus affecting cleaning efficiency and quality.

[0006] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0007] The present invention provides a road and bridge side guardrail cleaning device, including a support plate, on which two symmetrically arranged cleaning mechanisms are installed. Each cleaning mechanism includes a vertically arranged mounting roller, which can rotate on the support plate, and the top of the mounting roller is connected to a driving component.

[0008] At least one flexible water supply rotating cleaning component is provided on the surface of the mounting roller. The water supply rotating cleaning component contacts the side guardrail as the mounting roller rotates and continuously sprays water outward. Several evenly distributed brush bristles are fixed on the surface of the mounting roller.

[0009] The water supply rotating cleaning assembly is connected to the hollow inner cavity of the mounting roller.

[0010] In this technical solution, the water supply rotating cleaning assembly includes a connecting soft shell, and several equally spaced water outlet thin tubes are connected to the upper and lower surfaces of the connecting soft shell. The connecting soft shell is a tubular or flat cuboid structure.

[0011] The connecting soft shell is fixed to the outer wall of the mounting roller and communicates with the inner cavity of the mounting roller. The water outlet tube is set vertically and has water outlet holes on its surface.

[0012] In this technical solution, there are multiple flat connecting soft shells, and adjacent connecting soft shells are connected to each other through a connecting thin tube, and a soft cover is fitted on the surface of the connecting thin tube.

[0013] Preferably, the water outlet hole on the water outlet capillary is located at the end of the water outlet capillary or is formed on its annular side. When the water outlet hole is formed on the annular side of the water outlet capillary, the end of the water outlet capillary is closed. The surfaces connecting the soft shell and the soft cover are provided with brush bristles or covered with a cleaning cloth.

[0014] In this technical solution, the top of the mounting roller is mounted on a support plate and can rotate on the support plate. The bottom of the mounting roller is connected to a support frame through a connecting assembly. The support frame is fixed on the support plate. The bottom of the mounting roller is connected to an external water pump through the connecting assembly.

[0015] In this technical solution, the connecting assembly includes a connecting cover, which is sleeved on the connecting block of the tubular structure. The connecting block is fixed to the bottom of the mounting roller and communicates with the inner cavity of the mounting roller.

[0016] A connector is fitted onto the bottom surface of the connecting block. A rotational sealing structure is formed between the connecting block and the connecting cover, as well as between the connecting block and the connector. An external pipe for connecting an external water pump is fixed to the bottom of the connector.

[0017] This technical solution also includes a detection component for detecting whether the guardrail installation structure is stable. The detection component is installed on the load-bearing plate, and the detection unit of the detection component overlaps on the crossbeam at the top of the guardrail.

[0018] The detection end moves with the bearing plate on the surface of the guardrail beam to detect whether the flexible impact on the guardrail caused by the cleaning mechanism during the cleaning process causes abnormal vibration of the guardrail.

[0019] The detection assembly also includes a transmission unit that can amplify the amplitude, which transmits the amplified amplitude to the warning unit.

[0020] In this technical solution, the detection component includes a support frame, which is fixed on the bottom side wall of the support plate. The detection unit is set on the support frame and includes a guide telescopic part, which is fixed on the support frame in the transverse direction. A traveling pulley is installed on the end of the guide telescopic part near the middle of the support plate. The moving end of the guide telescopic part is connected to the transmission part, and the transmission part is connected to the warning part.

[0021] In this technical solution, the guide telescopic part includes an outer connecting rod arranged in a transverse direction. The outer connecting rod is fixed on the support frame and sleeved on the surface of the inner connecting rod. A traveling pulley is provided on the end of the inner connecting rod, and a spring is sleeved on the surface of the outer connecting rod.

[0022] The inner connecting rod moves back and forth with the traveling pulley that is attached to the guardrail beam, thereby driving the warning unit to move through the transmission unit.

[0023] In this technical solution, the transmission unit includes a mounting bracket, on which at least two gears are mounted, and all gears are distributed along the same vertical line, with adjacent gears meshing with each other;

[0024] Two gears located at the two edges are respectively connected to two horizontally arranged racks that mesh with each other. One rack is fixedly connected to the inner connecting rod via a connecting rod, and the other rack is connected to the warning unit via another connecting rod. The diameter of the gear that meshes with the rack connected to the inner connecting rod is larger than the diameter of the other gears.

[0025] In this technical solution, the warning unit includes a transmission vertical rod that passes through the surface of the support plate. A marking element is fixed to the top of the transmission vertical rod, and a transmission telescopic rod is rotatably connected to the bottom of the transmission vertical rod through the support element. The bottom of the transmission telescopic rod is rotatably connected to the transmission unit.

[0026] The transmission telescopic rod and the transmission vertical rod are arranged along the same line, and the transmission telescopic rod and the transmission vertical rod can rotate synchronously along the load-bearing member.

[0027] In this technical solution, the bearing component includes a bearing horizontal shaft and a bearing sleeve. The two ends of the bearing horizontal shaft are fixed to the bearing plate, the bearing sleeve is rotatably sleeved on the surface of the bearing horizontal shaft, and the transmission vertical rod and the transmission telescopic rod are respectively fixed on the outer walls of the two sides of the bearing sleeve.

[0028] Preferably, it also includes an audible warning device, which includes two symmetrically arranged striking blocks, the striking blocks being fixed on the transmission vertical rod, and a sound-producing block being fixed on a bearing plate on one side of the striking blocks.

[0029] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0030] The positive and progressive effects of this invention are as follows:

[0031] The water-supply rotary cleaning component in this design functions as both a cleaning actuator and a water spray unit, achieving an integrated design of the cleaning and water supply mechanisms. As the rotary cleaning component rotates synchronously with the mounting rollers and moves relative to the guardrail surface, cleaning water is continuously supplied through the component's internal channels and released from the corresponding spray points. This synchronizes the water flow and the rotary brushing action in both space and time, creating a combined cleaning method that integrates rinsing and friction.

[0032] Through the aforementioned synergistic effect, the water flow pre-wets and softens stains before the brush bristles contact the railing surface, reducing the adhesion strength of dirt. Simultaneously, during the brushing process, it promptly washes away loosened mud, dust, and other adhering substances, helping to prevent dirt from accumulating or re-adhering in the cleaning area, thereby improving cleaning efficiency and thoroughness. On the other hand, the centrifugal water-spraying effect generated during rotation enhances the dispersion and coverage of the water flow, allowing the cleaning water to act more evenly on the railing surface and its uneven parts or joints, further improving the overall cleaning effect.

[0058] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0059] like Figures 1-3 As shown, the road and bridge side guardrail cleaning device includes a support plate 1, on which two symmetrically arranged cleaning mechanisms are installed. Each cleaning mechanism includes a vertically arranged mounting roller 2, which can rotate on the support plate 1, and the top of the mounting roller 2 is connected to a drive component that drives its rotation.

[0060] At least one flexible water supply rotating cleaning component 5 is provided on the surface of the mounting roller 2. The water supply rotating cleaning component 5 contacts the side guardrail as the mounting roller 2 rotates and continuously sprays water outward. Several evenly distributed brush bristles 22 are fixed on the surface of the mounting roller 2.

[0061] The water supply rotating cleaning assembly 5 is connected to the inner cavity of the hollow mounting roller 2.

[0062] Example 1

[0063] In this embodiment, the water supply rotating cleaning assembly 5 includes a connecting soft shell 51, and a plurality of equally spaced water outlet thin tubes 52 are connected to the upper and lower surfaces of the connecting soft shell 51. The connecting soft shell 51 is a tubular or flat cuboid structure.

[0064] The connecting soft shell 51 is fixed on the outer wall of the mounting roller 2 and communicates with the inner cavity of the mounting roller 2. The water outlet tube 52 is set vertically and has water outlet holes 521 on its surface.

[0065] like Figures 16-18 As shown, there are multiple flat connecting soft shells 51, and adjacent connecting soft shells 51 are connected to each other through a connecting thin tube 531. A soft cover 532 is fitted onto the surface of the connecting thin tube 531.

[0066] The connecting tube 531 and the soft cover 532 together constitute the connecting part 53.

[0067] The flat connecting soft shell 51 has a larger contact area with the side guardrail, and can be better adapted to cleaning compared to the tubular structure.

[0068] Preferably, the water outlet hole 521 on the water outlet capillary 52 is located at the end of the water outlet capillary 52 or is formed on its annular side. When the water outlet hole 521 is formed on the annular side of the water outlet capillary 52, the end of the water outlet capillary 52 is closed. The surfaces connecting the soft shell 51 and the soft cover 532 are both provided with brush bristles 22 or covered with a cleaning cloth.

[0069] When the end of the water outlet tube 52 is closed, the cleaning water is sprayed out through the water outlet hole 521 on the side, which can be sprayed vertically towards the side guardrail.

[0070] At the same time, after water is passed through the connecting tube 531, it has a certain rigidity, thereby supporting the connecting soft shell 51 that is connected to it, so that it can fully contact the side guardrail.

[0071] The bristles 22 mounted on the roller 2 together form a cylindrical brush.

[0072] Preferably, in this technical solution, the structure inside the connecting shell 51 used to form a water supply path can be implemented in two ways. First, a connecting pipe is provided in the inner cavity of the connecting shell 51. The connecting pipe extends along the length of the connecting shell 51 and is connected to the connecting pipes located at both ends of the connecting shell 51. At the same time, it is connected to the water outlet capillary 52 used to spray out cleaning water, thereby forming a stable water supply path, so that the water flow can enter the connecting pipe from the connecting pipe and then be diverted to the water outlet capillary 52 and sprayed out.

[0073] Secondly, a connecting channel can be directly formed inside the connecting flexible shell 51. This channel can be integrally formed by the connecting flexible shell 51 itself or formed by opening flow channels. It is also connected to the connecting pipes at both ends of the connecting flexible shell 51 and to the outlet capillary pipe 52, thus realizing the transportation and distribution of cleaning water inside the connecting flexible shell 51. Either of these two structural forms ensures the continuity and stability of the water supply path while reducing the need for external piping, making the overall structure more compact.

[0074] Furthermore, within the inner cavity of the connecting soft shell 51, the space located outside the connecting pipe or connecting channel is preferably filled with a soft buffer layer. This buffer layer can be made of elastic rubber, foam material, or flexible polyurethane material. It serves to support and dampen the internal water supply structure when the water supply rotating cleaning assembly 5 rotates with the mounting roller 2 or contacts the guardrail for brushing. This buffer layer not only absorbs the impact and vibration generated during rotation and brushing contact, but also prevents displacement, wear, or damage to the connecting pipe or connecting channel under repeated bending or pressure, thereby improving the reliability and service life of the water supply structure.

[0075] Preferably, when the water sprayed from the water outlet 521 is insufficient for the water flow required for cleaning, additional water nozzles can be installed in the corresponding areas of the bearing plate 1, support frame 11, etc.

[0076] The connecting soft shell 51 is preferably made of a material with good flexibility, wear resistance, and pressure resistance to meet the comprehensive requirements of bending adaptability and structural strength during rotary brushing operations. Specifically, the connecting soft shell 51 can be made of polyurethane material. Polyurethane soft shells have high wear resistance and tear resistance, and are not easily damaged or deformed under long-term contact and friction with the guardrail surface and brush bristles, thereby helping to extend service life and ensure the stable operation of cleaning.

[0077] Furthermore, to improve the pressure resistance and tensile strength of the connecting flexible shell 51 during water supply, a reinforcing braided layer, such as a polyester fiber braided layer or a high-strength fiber reinforcing layer, can be provided inside the connecting flexible shell 51. This allows the connecting flexible shell to maintain good structural stability when subjected to water flow pressure and centrifugal force, preventing bulging, collapse, or twisting. Simultaneously, the outer layer material of the connecting flexible shell can possess certain elasticity and resilience, enabling it to bend smoothly and quickly return to its original shape during synchronous rotation with the mounting roller 2, thereby improving the reliability of rotational operation.

[0078] Furthermore, the connecting flexible material also possesses excellent weather resistance and aging resistance to adapt to common outdoor environmental conditions encountered in bridge or road guardrail cleaning operations, such as sun exposure, rain, and temperature changes. By selecting the connecting flexible material with the aforementioned structure and materials, not only can the stable delivery of cleaning water be ensured, but it can also withstand continuous friction and vibration during the rotating brushing process, thereby improving the overall service life and operational efficiency of the water supply rotating cleaning assembly 5.

[0079] Example 2

[0080] In this embodiment, the top of the mounting roller 2 is mounted on the support plate 1 and can rotate on the support plate 1. The bottom of the mounting roller 2 is connected to the support frame 11 through the connecting component 3. The support frame 11 is fixed on the support plate 1 and has a "C" shaped structure, bypassing the mounting roller 2 and the brush bristles 22 on its surface and the water supply rotating cleaning component 5. The bottom of the mounting roller 2 is connected to an external water pump through the connecting component 3.

[0081] like Figure 8 As shown, the connecting assembly 3 includes a connecting cover 31, which is sleeved on the connecting block 21 of the tubular structure. The connecting block 21 is fixed to the bottom of the mounting roller 2 and communicates with the inner cavity of the mounting roller 2.

[0082] A connector 32 is fitted onto the bottom surface of the connecting block 21. A rotational sealing structure is formed between the connecting block 21 and the connecting cover 31, as well as between the connecting block 21 and the connector 32. An external pipe 33 for connecting an external water pump is fixed to the bottom of the connector 32. The external pipe 33 passes through the support frame 11 laterally and can be laid along the axial direction of the support frame 11.

[0083] The water pump and water source are connected to the external pipe 33. The clean water is pumped into the external pipe 33 by the water pump, and then enters the inner cavity of the mounting roller 2 through the connector 32 and the connecting block 21 in sequence, and finally sprayed out from the water outlet 521.

[0084] The support plate 1 is connected to an external moving mechanism, which drives the support plate 1 and its two cleaning mechanisms to move along the length of the guardrail. The two cleaning mechanisms are located on both sides of the guardrail.

[0085] The extension shaft 23 at the top of the mounting roller 2 is connected to the drive component, which is a motor.

[0086] Example 3

[0087] like Figure 1 and Figure 10 As shown, it also includes a detection component 6 for detecting whether the guardrail installation structure is stable. The detection component 6 is installed on the bearing plate 1, and the detection unit of the detection component 6 overlaps on the crossbeam at the top of the guardrail.

[0088] The detection end moves with the bearing plate 1 on the surface of the guardrail beam to detect whether the flexible impact of the cleaning mechanism on the guardrail during the cleaning process causes abnormal vibration of the guardrail. When the vibration is within the normal range, it indicates that the guardrail structure is stable. When the vibration amplitude is too large, it indicates that the guardrail structure is unstable.

[0089] The detection component 6 also includes a transmission unit 64 that can amplify the amplitude, and the transmission unit 64 transmits the amplified amplitude to the warning unit.

[0090] By setting up a cleaning mechanism that applies a periodic impact force or contact disturbance with a certain degree of flexibility to the guardrail surface during cleaning, the guardrail generates controllable vibrations without compromising structural safety. When the guardrail is loose, has failed connectors, or its overall stability is reduced, it is more likely to produce a larger amplitude vibration response under the same cleaning force. By setting up a detection unit to sense and determine the vibration amplitude of the guardrail in real time, the structural stability of the guardrail can be identified simultaneously during the cleaning process, enabling auxiliary detection of the guardrail's safety performance.

[0091] Compared to traditional methods that require dedicated shutdowns for inspection or rely on manual shaking checks, this solution organically combines cleaning operations with safety testing. Stability screening can be completed without significantly increasing maintenance procedures and time, thus improving the maintenance efficiency of bridge or road guardrails. Furthermore, by quantifying vibration amplitude or using threshold judgments, the uncertainty arising from human experience can be reduced, improving the objectivity and consistency of the test results.

[0092] Furthermore, because the cleaning mechanism applies a flexible impact or buffered contact force, it can reduce the risk of impact damage to the guardrail surface coating and structural components while ensuring the effectiveness of the inspection, thus extending the service life of the guardrail. This solution also has advantages such as relatively simple structural implementation, easy integration with existing cleaning equipment, and strong environmental adaptability, making it suitable for daily maintenance and safety status early warning in various scenarios such as bridge guardrails, highway guardrails, and urban road guardrails.

[0093] like Figures 12-15 As shown, the detection component 6 includes a support frame 61, which is fixed on the bottom side wall of the support plate 1. The detection unit is mounted on the support frame 61. The detection unit includes a guide telescopic part 62, which is fixed laterally on the support frame 61. A traveling pulley 63 is installed on the end of the guide telescopic part 62 near the middle of the support plate 1. The moving end of the guide telescopic part 62 is connected to the transmission part 64, which is connected to the warning part.

[0094] The guide telescopic part 62 includes an outer connecting rod 621 arranged in a transverse direction. The outer connecting rod 621 is fixed on the support frame 61. The outer connecting rod 621 is sleeved on the surface of the inner connecting rod 622. A traveling pulley 63 is provided on the end of the inner connecting rod 622. A spring is sleeved on the surface of the outer connecting rod 621. The two ends of the spring are respectively fixed on the outer walls of the outer connecting rod 621 and the inner connecting rod 622.

[0095] The inner connecting rod 622 moves back and forth with the traveling pulley 63 that is attached to the guardrail beam, thereby driving the warning unit to move through the transmission unit 64.

[0096] The walking pulley 63 is the detection end of the detection component 6.

[0097] The transmission unit 64 includes a mounting bracket 645 on which at least two gears are mounted, and all gears are distributed along the same vertical line, with adjacent gears meshing with each other.

[0098] Two gears located at the two side edges are respectively arranged in two transversely arranged racks that mesh with each other. The racks are arranged parallel to the outer connecting rod 621. One rack is fixedly connected to the inner connecting rod 622 through a connecting rod, and the other rack is connected to the warning unit through another connecting rod. The diameter of the gear that meshes with the rack connected to the inner connecting rod 622 is larger than the diameter of the other gears.

[0099] Specifically, when there are two gears, the two gears are a drive gear 641 and a driven gear 642. The drive gear 641 and the driven gear 642 mesh with each other, and the diameter of the drive gear 641 is larger than that of the driven gear 642. A drive rack 643 is meshed and connected to one side of the drive gear 641. The drive rack 643 is fixedly connected to the inner connecting rod 622 through the first connecting rod 6431. A drive rack 644 is meshed and connected to one side of the driven gear 642. The drive rack 644 is connected to the warning unit through the second connecting rod 6441.

[0100] Preferably, sliding sleeves 65 are fitted onto both ends of the rack, and the sliding sleeves 65 on the same side of the two racks are connected to each other by a fixing rod 651. The fixing rod 651 is fixed to one of the surfaces of the support frame 61, the outer connecting rod 621 and the support plate 1 by a rod.

[0101] The amplitude is increased by increasing the transmission ratio through gears of different diameters.

[0102] The warning unit includes a transmission vertical rod 66, which passes through the connecting slot 4 on the surface of the bearing plate 1. A marking member 661 is fixed to the top of the transmission vertical rod 66, and a transmission telescopic rod 67 is rotatably connected to the bottom of the transmission vertical rod 66 via a bearing member 68. The bottom of the transmission telescopic rod 67 is rotatably connected to the transmission unit 64.

[0103] The transmission telescopic rod 67 and the transmission vertical rod 66 are arranged in the same line, and the transmission telescopic rod 67 and the transmission vertical rod 66 can rotate synchronously along the bearing member 68.

[0104] The bottom of the transmission telescopic rod 67 is rotatably connected to the corresponding connecting rod.

[0105] The bearing component 68 includes a bearing horizontal shaft 681 and a bearing sleeve 682. The two ends of the bearing horizontal shaft 681 are fixed on the bearing plate 1. The bearing sleeve 682 is rotatably sleeved on the surface of the bearing horizontal shaft 681. The transmission vertical rod 66 and the transmission telescopic rod 67 are respectively fixed on the outer walls of the two sides of the bearing sleeve 682.

[0106] Preferably, it also includes an audible warning device, which includes two symmetrically arranged striking blocks 662. The striking blocks 662 are fixed on the transmission vertical rod 66, and a sound-producing block 69 is fixed on the bearing plate 1 on one side of the striking blocks 662.

[0107] Preferably, the sign 661 is a brightly colored block structure or a brightly colored flag structure.

[0108] When the amplitude of the guardrail is too large, it is amplified by the transmission unit 64 and drives the transmission rod 66 to swing around the bearing member 68, thereby driving the striking blocks 662 on both sides to strike the sound blocks 69 on both sides, giving an audible warning. Together with the large-amplitude swinging sign 661, it completes a dual warning with both visual and auditory warnings.

[0109] When the sliding block swings with the guardrail beam, it causes the inner connecting rod 622 to slide synchronously inside the outer connecting rod 621. The spring deforms, and the inner connecting rod 622 drives the corresponding rack to move synchronously through the corresponding connecting rod, thereby driving the largest diameter gear to rotate. The gear drives the other gears meshing with it to rotate synchronously, thereby driving another rack to make a larger movement.

[0110] A rack with a larger range of motion pushes the bottom of the transmission telescopic rod 67 to swing through the corresponding connecting rod, thereby causing the transmission vertical rod 66 to swing synchronously.

[0111] Preferably, there are two detection components 6, which are arranged symmetrically. That is, the traveling pulleys 63 of the two detection components 6 are respectively clamped on the outer walls of the two sides of the guardrail beam.

[0112] The end of the inner connecting rod 622 is connected to the traveling pulley 63 via an adjustable-length connecting telescopic rod 623.

[0113] This invention is not limited to the embodiments described above. Any changes in shape or structure shall fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
