Description

Technical Field

[0001] The invention specifically relates to a road bridge side guardrail cleaning device, belonging to the technical field of road bridge guardrail cleaning. Background Art

[0002] The guardrails of roads and bridges are exposed to the outside world for a long time, and dust and stains will cover the surface of the guardrails, which can easily cause pollution to the guardrails. In the prior art, the cleaning of the guardrails is mostly done by sanitation workers using rags to wipe them. It is difficult to fully clean the guardrails of roads and bridges, and the operation is time-consuming and laborious. In addition, most of the existing cleaning devices are single-sided cleaning with low cleaning efficiency. Some use double-sided cleaning, but when cleaning, the cleaning distance cannot be adjusted according to the width of the guardrail. For this reason, Chinese Patent Publication No.: CN118814681A provides a road and bridge side guardrail cleaning device, including a support column, a water tank is installed on the top of the support column, and the water tank is installed on the top of the support column. The outside of the box is connected to a water pipe, and a water pump is arranged inside the water tank; the structure pushes the inner side of the support column to both sides of the guardrail, and adjusts the height between the support column and the guardrail by adjusting the bolts on both sides of the support column. During cleaning, the guardrail is cleaned when the first cleaning roller contacts the second cleaning roller and the outside of the guardrail; the structure adopts a cleaning roller for cleaning, and since the railing is not a planar structure, the cleaning roller cannot contact all parts of the guardrail, and the guardrail cannot be thoroughly cleaned; and during the cleaning process, water resources are seriously wasted; in addition, most of the existing guardrails are arranged on both sides of roads and bridges, and due to road restrictions, cleaning vehicles cannot enter for operation.
