Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of guardrail cleaning, in particular to a guardrail cleaning device and method for highway maintenance. BACKGROUND

[0002] Highway guardrails can prevent vehicles from driving off the road or prevent out-of-control vehicles from crossing the central median and entering the opposite lane. Line-of-sight inducing facilities are used by drivers to determine the direction of the road beyond the line of sight. The movement trajectory of the vehicle collision protection barrier should be smooth to allow the vehicle to return to normal driving direction and reduce the likelihood of secondary accidents. Isolated and closed facilities are often used in towns and suburban areas with high traffic, rural markets, villages, and schools with high population density or high livestock activity.

[0003] A municipal road isolation guardrail cleaning device (CN110387847A) includes an arcuate frame, a universal wheel fixedly installed at the bottom of the arcuate frame, a guardrail guide mechanism fixedly connected to the front of the arcuate frame, and a guardrail cleaning mechanism arranged inside the arcuate frame. The municipal road isolation guardrail cleaning device has a longitudinal rail arranged on the front of the arcuate frame. The longitudinal rail allows the two guide U-shaped connecting blocks to be close to the crossbeam of the guardrail. The guide rollers inside the guide U-shaped connecting blocks can contact the crossbeam of the guardrail, allowing the arcuate frame to move along the guardrail during walking. This effectively facilitates the cleaning operation of the guardrail cleaning mechanism on the guardrail. Although this device can clean both sides of the guardrail simultaneously, it still has some major defects:

[0004] 1. The device does not have a drying function for the cleaned guardrail surface, resulting in a large amount of water stains remaining on the surface of the guardrail after cleaning. These water stains quickly mix with the dust stirred up by the road and adhere to the surface of the guardrail, forming new dirt and greatly reducing the cleaning effect. This greatly increases the frequency of cleaning the guardrail and results in a significant increase in cost.

[0005] 2. The device only has one set of cleaning rollers, which can only clean the guardrail once, making it impossible to effectively clean the dirt on the surface of the guardrail.

[0006] To address the above technical deficiencies, a solution is proposed. SUMMARY

A water supply pipe (707) is connected to the outside of the nozzle (706). The end of the water supply pipe (707) away from the nozzle (706) is connected to an external water supply device. A baffle (708) is fixed to one side of the shielding frame (701) by bolts.

4. A guardrail cleaning device for highway maintenance according to claim 3, characterized in that, The support frame (702) is fixed to the outside by spot welding with a mounting plate (709). A top rod (710) is rotatably connected to one side of the mounting plate (709) at equal distances. A slide rail (711) is fixedly connected to one side of the mounting plate (709) at equal distances. A slider (712) is slidably connected inside the slide rail (711). A connecting rod (713) is rotatably connected to one side of the slider (712). One end of the connecting rod (713) is rotatably connected to the support fixedly connected to the side of the top rod (710). A compression spring is fixedly connected between the slider (712) and the inner wall of the slide rail (711). A scraper (714) is provided at one end of the top rod (710).

5. A guardrail cleaning device for highway maintenance according to claim 4, characterized in that, The top of the sliding plate 1 (5) and the sliding plate 2 (6) are respectively equipped with motor 1 (10) and motor 2 (11) for driving gear 3 and gear 4. The top of the support frame 1 (702) and the support frame 2 (800) are respectively equipped with gear 5 (12) for driving shaft 1 and shaft 2. The gear 5 (12) is connected to the corresponding gear 3 and gear 4 through chain 3 (13).

6. A method for operating a guardrail cleaning device for highway maintenance as described in claim 4, characterized in that, Includes the following steps: Step 1: Adjust the position of the horizontal plate (1) by using an external robotic arm until the cleaning range of the sweeping roller (703) covers the entire guardrail. Then, start the electric push rod (16). The output end of the electric push rod (16) drives the slide (4) to move. Through the cooperation of the drive arm (15) and the rotating plate (14), the two sliding plates (5) bring the two sliding plates (6) closer to each other until the sweeping roller (703) is close to the two symmetrically arranged sides of the guardrail. Step 2: The external traction device drives the horizontal plate (1) to move. At the same time, the nozzle (706) works with the first set of high-speed rotating cleaning rollers (703) to use the bristles to initially clean the dirt on the guardrail surface. Then, the top rod (710) is assisted by the compression spring and the torsion spring to further scrape the guardrail surface with the scraper (714). The scraper (714) effectively removes the dirt on the guardrail surface. Then, the nozzle (706) works with the second set of high-speed rotating cleaning rollers (703) to further clean the dirt on the guardrail surface with the bristles, so that the guardrail surface is in a cleaner state. Step 3: The wiping mat (803) adheres to the surface of the guardrail under the action of the abutment block (810). The wiping mat (803) uses the water absorption properties of the fabric to remove water from the surface of the guardrail. The area of ​​the guardrail wiped by the wiping mat (803) is dried by the blower (813), so that the surface of the guardrail is in a clean and dry state, avoiding the problem of dust re-attaching due to a large amount of water adhering to the surface of the guardrail.
