Technical Field
[0001] The utility model relates to the technical field of stain resistance detection for road marking paint, in particular to a road performance detection device. Background Art
[0002] Road markings are the lifeline for controlling and guiding road traffic, and are usually painted with road marking paint. With the rapid development of my country's highway transportation industry, the investment and construction of highways have been continuously increased, and the demand for road marking paint has been continuously increasing. In recent years, road marking paint has made a series of leaps in terms of types, performance and construction technology. Road marking paint products can usually be divided into four types: solvent-based road marking paint, hot-melt road marking paint, two-component road marking paint and water-based road marking paint. In order to improve its retro-reflective performance, glass beads can also be sprinkled during the construction of the marking paint.
[0003] The existing announcement number is CN213749543U, which is a device for testing the anti-fouling performance of road marking paint. This patent uses manpower to push the roller to move on the track defined by the slide rail to simulate the process of the wheel rolling over the road marking paint during actual use, filling the gap in the current device for testing the anti-fouling performance of road marking paint.
[0004] The inventors found in their daily work that during the use of the above-mentioned road marking paint stain resistance testing device, there is no limit support for the push rod bracket, which will cause friction between the push rod bracket and the device, resulting in certain losses.

The limit slide bar moves inside the slide groove to drive the connecting plate to move. The connecting plate moves to drive the slide plate to move on the surface of the slide rod. The slide plate moves on the surface of the slide rod to drive the rotating shaft to move. The rotating shaft moves to drive the pressure roller to move. The pressure roller uses its own weight to apply downward pressure on the pollutants and performs reciprocating motion, thereby simulating the rolling of the road marking paint by the wheels in actual use. After repeated rolling for several times, the contamination of the coating is tested. Through the cooperation of the above structure, the connecting plate can cooperate with the limit slide bar to move inside the slide groove when moving, and the limit slide bar is used to limit the connection plate, so that the connection plate will not tip forward or backward, thereby avoiding friction with the device and causing loss.
