Description

Technical Field

[0001] The utility model relates to the technical field of highway detection equipment, in particular to a highway anti-skid detection device. Background Art

[0002] In the prior art, the anti-skid performance of a road refers to the ability of the road surface to prevent a vehicle from sliding under specific weather conditions, that is, the magnitude of the frictional force generated between the road surface and the tire during sliding. The strength of the road surface anti-skid performance is determined by many aspects, such as the road maintenance level, construction technology level, selection of building materials, and road surface design.

[0003] In some existing devices, a water spraying mechanism is provided. Water is pumped by a water pump from a water storage tank through a water outlet pipe to a sprayer for spraying, which can effectively simulate a rainy road surface for anti-skid detection. The controller can adjust the water pump to change the water spraying amount, improving the authenticity of the device in simulating rainy weather. However, in actual use, the anti-skid performance test of a highway needs to be carried out over a long distance and at multiple line positions. For the test of simulating a rainy road surface, the amount of water consumed is relatively large. Relying solely on the water flow inside the water storage tank is not sufficient to meet the test requirements under various rainfall conditions. Summary of the Utility Model

A stabilizing pressing plate 10 is fixedly installed at the top end of the connecting column 9. The lower surface of the stabilizing pressing plate 10 is set as an arc surface, and the air flow velocity on the upper surface is less than that on the lower surface, generating a downward pressure on the stabilizing pressing plate 10, thereby keeping the gas collecting pipe 7 stable during the movement following the test tractor 1.
