Description

Technical Field

[0001] The utility model belongs to the field of maintenance equipment, in particular to a cleaning device for a corrugated beam guardrail. Background Art

[0002] The WB guardrail, a safety feature widely used at highway median openings, consists of two corrugated steel guardrail panels fixed between two posts. This design not only allows for greater flexibility in installation and maintenance, but also allows for quick and easy insertion of the posts into pre-set holes during normal highway operation, effectively providing road isolation and protection. Furthermore, the WB guardrail's appearance complements the outer guardrail strips, creating a uniform, aesthetically pleasing visual effect. However, WB guardrails also face challenges in practical use. The high speeds of high-speed vehicles on highways create a significant amount of dust, which often settles on the surface of the WB guardrail, affecting its aesthetics and increasing the risk of corrosion, rust, and cracking of the protective film. Therefore, regular cleaning and maintenance of WB guardrails is crucial. Currently, manual water spraying is the primary method for cleaning WB guardrails. Although this cleaning method can remove dust on the surface of the guardrail to a certain extent, its working efficiency is relatively low, and due to the limitation of the bending angle of the corrugated beam guardrail, the cleaning effect is difficult to guarantee.

The present application separates the corrugated beam guardrail cleaning device into a transfer mechanism, a water supply mechanism, a cleaning mechanism and a central control unit. The installation of the transfer mechanism facilitates the overall displacement of the cleaning device. The water tank 1 in the water supply mechanism can ensure water supply while providing a counterweight for the cleaning device to prevent the clamping and cleaning components in the cleaning mechanism from tipping over during the clamping process of the corrugated bridge guardrail. The two sets of cleaning roller assemblies 5 complete the clamping of the corrugated bridge guardrail under the push of the second telescopic member 4 and complete the cleaning under the flushing of the nozzle. By designing the shape of the cleaning roller 501 to fit the corrugated beam guardrail, the bending part of the corrugated beam guardrail can be cleaned without being restricted by the bending angle, thereby ensuring the cleaning effect. This solves the problems of low efficiency and difficulty in ensuring the cleaning effect of manual water spray cleaning of the corrugated beam guardrail in the prior art.

[0035] In this embodiment, please refer to Figure 2The side wall of the water storage tank 1 away from the corrugated beam guardrail is recessed inward to form a guide groove in the vertical direction; the support frame body 3 is a U-shaped support frame, one end of the support frame body 3 cooperates with the guide groove, and the other end is fixed with two cleaning frames 301, the openings of the two cleaning frames 301 are opposite to each other, and are respectively fixedly connected to the second telescopic member 4, and the two cleaning frames 301 are respectively provided with water holes, so that the output end of the infusion tube passes through the cleaning frame and supplies water to the cleaning roller assembly 5. This application designs the support frame body 3 into a U-shaped support frame, and cooperates with the guide groove of the water tank side wall away from the corrugated beam guardrail on the other end to complete the clamping and cleaning of the corrugated beam guardrail. The design of the U-shaped support frame enables the support frame body 3 to withstand various forces from the clamping and cleaning assembly and the cleaning operation. The end away from the corrugated beam guardrail and the guide groove of the water tank side wall can provide it with support force, thereby ensuring the stability of the support frame during operation.

The second telescopic part 4 on the same side completes the recovery action under the control of the central control unit (and stops the cleaning work on the same side at the same time) to avoid the cleaning roller assembly 5 from colliding with the column. After the second rangefinder completes the distance measurement of the column, it transmits a signal to the central control unit. The second telescopic part 4 on the same side completes the pushing action under the control of the central control unit (and starts the cleaning work at the same time) to continue cleaning the corrugated beam guardrail.

[0039] In this embodiment, the operating mechanism includes a transfer body and a handrail; universal wheels are provided at the bottom of the transfer body for supporting the movement of the transfer body; the handrail is provided at the tail end of the transfer body for easy holding by construction workers.
