Description

Technical Field

[0001] This utility model relates to the field of highway maintenance equipment technology, and in particular to a highway guardrail cleaning device. Background Technology

[0002] Highway guardrails are important facilities for ensuring highway traffic safety, preventing vehicles from leaving the road and reducing traffic accidents. However, highway guardrails are exposed to the outdoor environment for a long time, making them prone to absorbing pollutants such as dust, oil, and bird droppings. These pollutants not only affect the aesthetics of the highway and reduce the overall image of the road, but also corrode the guardrails, shorten their service life, and increase maintenance costs.

[0003] Existing guardrail cleaning devices generally use a structure that clamps the guardrail in the middle and uses brushes to scrub both sides of the guardrail simultaneously. However, this structure has obvious drawbacks in actual use. When the cleaning device reaches the main support of the guardrail, it will get stuck, which will prevent the cleaning work from proceeding normally, greatly affect the cleaning efficiency, and increase the risk of equipment damage.

[0004] An existing patent (publication number: CN211446741U) discloses a highway guardrail cleaning and maintenance device. Based on the structure of highway guardrails, it is equipped with an elastic telescopic rod that is inclined to the guardrail panel. During operation, it can bypass the guardrail post support without causing obstruction and has a good cleaning effect. The structure is simple and can be completed by modifying a general motor vehicle.

[0005] Existing patents offer solutions to the aforementioned problems, but their cleaning effects are unsatisfactory. In actual use, due to the lack of an effective cleaning structure, relying solely on mechanical friction with a brush to clean the railing cannot thoroughly remove stubborn stains such as asphalt and grease. Furthermore, it cannot effectively clean some details of the railing, such as gaps and corners, which can easily lead to contamination and repeated cleaning, affecting the overall cleaning quality of the railing and reducing the practicality of the device.

[0006] Therefore, a highway guardrail cleaning device is proposed. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A highway guardrail cleaning device includes an L-shaped fixing plate 1, a cleaning component 2 is movably connected inside the L-shaped fixing plate 1, and a sweeping component 3 is fixedly connected inside the cleaning component 2. The sweeping component 3 includes a fixing block 301, a bidirectional screw 302 is rotatably connected inside the fixing block 301, and a moving motor 303 is fixedly connected to the front side of the bidirectional screw 302.

[0029] The cleaning component 2 includes a U-shaped block 201, with U-shaped jet blocks 202 fixedly connected to both sides inside the U-shaped block 201, and a storage tank 203 fixedly connected to the top of the U-shaped block 201. An air supply pipe 204 is fixedly connected to the front side of the top of the U-shaped jet block 202, and a pressurizing fan 205 is fixedly connected between the opposite sides of the two air supply pipes 204. A delivery pump 206 is fixedly connected to the bottom of both sides of the storage tank 203, and a delivery pipe 207 is fixedly connected to the side of the delivery pump 206 away from the storage tank 203. The other end of the delivery pipe 207 extends into the interior of the U-shaped block 201 and is fixedly connected to a spray plate 208.

[0030] In this embodiment: the moving motor 303 drives the bidirectional screw 302 to rotate, causing the threaded sleeve 304 to move smoothly. Simultaneously, the slider 305 moves within the fixed block 301, which in turn pushes the fixed bracket 306 and the brush roller 307 to move to opposite sides, bringing the brush roller 307 into contact with the guardrail surface. At the same time, the rotating motor 308 is activated, causing the brush roller 307 to rotate smoothly, achieving efficient cleaning of guardrails of different specifications and improving the ease of use of the cleaning component 3. Then, through the combined use of the delivery pump 206 and the delivery pipe 207, the cleaning solution in the storage tank 203 is... The cleaning solution flows smoothly into the spray plate 208 and is then evenly sprayed onto the surface of the guardrail. This dissolves stubborn stains, facilitating cleaning and improving the cleaning effect. Furthermore, the pressurized blower 205 pressurizes the outside air and delivers the high-pressure airflow through the air pipe 204 to the U-shaped jet block 202. Finally, the U-shaped jet block 202 sprays the solution evenly and quickly onto the guardrail surface, rapidly drying the water and forming a protective drying layer. This effectively prevents dust adhesion, ensuring comprehensive cleaning and enhancing the device's practicality.

[0031] Specifically, such as Figure 5As shown, threaded sleeves 304 are threadedly connected to the front and rear sides of the surface of the bidirectional screw 302, and sliders 305 are rotatably connected to the surfaces of the two threaded sleeves 304. Fixed brackets 306 are fixedly connected to the bottom of the two sliders 305, and brush rollers 307 are movably connected inside the two fixed brackets 306. A rotating motor 308 is fixedly connected to the bottom of the brush rollers 307.

[0032] Specifically, such as Figure 5 As shown, the bottom of the fixing block 301 is provided with a groove 4 for use with the slider 305, and the bidirectional screw 302 is located inside the groove 4.

[0033] Specifically, such as Figure 3 As shown, a hydraulic cylinder 5 is fixedly connected to the top of the L-shaped fixed plate 1, and the bottom of the hydraulic cylinder 5 passes through the L-shaped fixed plate 1 and is fixedly connected to the U-shaped block 201. A T-shaped moving groove 6 is provided on the front side of the inner wall of the L-shaped fixed plate 1. A T-shaped moving block 7 is slidably connected inside the T-shaped moving groove 6, and the front side of the T-shaped moving block 7 is fixedly connected to the U-shaped block 201.

[0034] In this embodiment: the T-shaped moving block 7 and the T-shaped moving groove 6 work together to make the hydraulic cylinder 5 drive the U-shaped block 201 to move smoothly under the constraint of the T-shaped moving block 7, and simultaneously drive the brush roller 307 to rise and fall smoothly. This not only allows for precise adjustment of the height of the brush roller 307 to meet the cleaning needs of guardrails of different heights, but also simplifies the installation process of the cleaning component 3 and improves the ease of use of the cleaning component 3. Then, the slider 305 and the slide groove 4 work together to make the bidirectional screw 302 drive the threaded sleeve 304 to move smoothly, and simultaneously push the slider 305 to move smoothly under the restriction of the slide groove 4. This, in turn, drives the fixed bracket 306 and the brush roller 307 to move smoothly to the opposite side, so that they come into contact with the surface of the guardrail, thus achieving the cleaning of guardrails of specific specifications and improving the cleaning effect of the guardrails.

[0035] Specifically, such as Figure 4 As shown, an air inlet pipe 8 is fixedly connected to the front side of the pressurizing blower 205, and a filter screen 9 is fixedly connected to the side of the air inlet pipe 8 away from the pressurizing blower 205.

[0036] Specifically, such as Figure 1 , Figure 4 As shown, an observation glass 10 is embedded inside the front side of the storage box 203, and an inlet valve 11 is fixedly connected to the top of the storage box 203.

[0037] In this embodiment: the combined use of the air inlet pipe 8 and the filter screen 9 not only expands the air collection range and increases the air collection efficiency, but also filters impurities in the outside air, ensuring the cleanliness of the incoming air, preventing the pressurized fan 205 from being damaged by impurities, ensuring the stable operation of the equipment's drying function, and improving the ease of use of the device. Then, by observing the combined use of the observation glass 10 and the liquid inlet valve 11, not only can the situation inside the storage tank 203 be observed in real time, but the cleaning liquid can also be added in time when it is insufficient, ensuring a continuous supply of cleaning liquid, providing a guarantee for efficient cleaning of the guardrail, and improving the ease of use of the cleaning component 2.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a movable arm 12 is fixedly connected to the rear side of the L-shaped fixing plate 1, and the other end of the movable arm 12 is fixedly connected to the car.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a signal receiving controller 13 is fixedly connected to the rear side of the top of the L-shaped fixing plate 1, and the signal receiving controller 13 is electrically connected to the cleaning component 3 and the cleaning component 2.

[0040] In this embodiment: the movable arm 12 not only allows the equipment to be closely connected to the vehicle, but also allows for flexible adjustment of the equipment's direction, enabling the vehicle to move the equipment smoothly along the guardrail, facilitating the cleaning of the guardrail. Simultaneously, the signal receiving controller 13 can receive signals from external operators' terminal devices in real time and precisely control the operation of the sweeping component 3 and the cleaning component 2. It can flexibly adjust the position of the brush roller 307 to adapt to different guardrail specifications, spray cleaning fluid onto the guardrail to dissolve stubborn stains, and simultaneously use high-pressure airflow to quickly dry water stains, forming a protective layer to prevent dust adhesion, ensuring the cleaning effect of the guardrail and improving the practicality of the device.

[0041] Working Principle: When cleaning highway guardrails, the movable arm 12 is first installed on a vehicle, allowing the vehicle to move the equipment smoothly along the guardrail. The movable arm 12 also allows for flexible adjustment of the equipment's direction. Then, the hydraulic cylinder 5 is activated, causing the U-shaped block 201 to move smoothly under the constraint of the T-shaped moving block 7, simultaneously raising and lowering the sweeping assembly 3. This adapts to the cleaning needs of guardrails of different heights and simplifies the installation process of the sweeping assembly 3. When the brush roller 307 moves to the appropriate position, the operator can remotely control the sweeping assembly 3 and the cleaning assembly 2 using the signal receiver controller 13. Then, the moving motor 303 is activated, driving the bidirectional screw 302 to rotate, causing the threaded sleeve 304 to move smoothly, simultaneously moving the slider 305 and the fixed bracket 306 to opposite sides, thereby pushing... The moving brush roller 307 contacts the guardrail surface, completing the equipment installation and debugging, and enters the cleaning stage. The rotating motor 308 is started, driving the brush roller 307 to rotate smoothly. At the same time, the delivery pump 206 is started, so that the cleaning solution in the storage tank 203 is delivered to the spray plate 208 through the delivery pipe 207, and then evenly sprayed on the guardrail surface through the spray plate 208. This can dissolve stubborn stains and achieve efficient cleaning of guardrails of different specifications. During the guardrail cleaning process, the pressurizing fan 205 is started to pressurize the outside air and deliver the high-pressure airflow through the air supply pipe 204 to the U-shaped air jet block 202. Finally, the U-shaped air jet block 202 sprays evenly and quickly onto the guardrail surface, which can quickly dry the water stains on the guardrail surface, forming a protective dry layer to prevent dust from adhering to the guardrail surface again, ensuring the cleaning effect of the guardrail.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
