Description

Technical Field

[0001] This invention relates to the field of traffic operation marking robot technology, specifically to an intelligent traffic operation marking and layout robot. Background Technology

[0002] Traffic lanes and parking lines on roads are generally marked by spray painting vehicles. Large spray painting vehicles require manual driving, while small ones require manual pushing. The paint is sprayed and solidified on the ground at a certain width to form road traffic lines. Robots control the completion of traffic marking operations. They have a longer battery life, significantly improved accuracy and efficiency, and stable and reliable construction quality. They are suitable for newly built highways, grass, gravel and other rough road surfaces, and can be used in various harsh weather conditions. They can also work in conjunction with other marking equipment. A road marking device with application number CN110965452A allows for road marking after the paint is loaded and the device is pushed. The device has three settings: drawing dashed lines, drawing solid lines, and stopping the drawing. The line width can be adjusted by rotating the adjusting bolt on the line width adjustment device. The drying device allows the drawn markings to dry faster. It also provides an automatic cap opening reminder when the paint is almost used up. The solid / dark line switching device is connected to the vehicle frame, the universal joint structure is connected to the solid / dark line switching device, the line width adjustment device is connected to the vehicle frame, the line width adjustment device is connected to the universal joint structure, the paint bucket is connected to the vehicle frame, the drying device is connected to the vehicle frame, the large conveyor belt is connected to the vehicle frame, the large conveyor belt is connected to the solid / dark line switching device, the small conveyor belt is connected to the vehicle frame, the small conveyor belt is connected to the drying device, the hose is connected to the line width adjustment device, and the hose is connected to the paint bucket. However, this road marking equipment is not convenient for trimming the lines during use. The sprayed lines solidify on the ground, and some excess paint will form on the edges of the lines, creating noise and affecting the quality of the marking. A road marking device with application number CN215482221U includes a mounting plate and a drive motor. A storage bin is located on the upper left of the mounting plate, and the drive motor is installed inside the left end of the mounting plate. A cleaning brush is connected to the output end of the drive motor. A positioning rod is located on one side of the mounting plate, and a connecting block is located on the outer side of the adjusting rod. A limit rod is installed on the right side of the bearing plate, and a second nozzle is installed on the right side of the first nozzle. This road marking device, while controlling the rotation of the cleaning brush to remove road dust, can drive the mounting blocks, whose outer surfaces have a toothed structure, to rotate in opposite directions via a connecting belt. This causes the push rod and support sleeve to slide relative to each other. During this process, the support sleeve deflects, causing the push rod and push plate to rotate and open, clearing away gravel and other debris from the road surface for subsequent marking. The marked lines also have a long service life. However, this marking device protects the marked lines, as the surface of the lines easily absorbs environmental dust during the solidification and drying process, reducing the clarity of the line surface. Some existing road marking equipment is not convenient for trimming the painted lines during use. Directly painted lines will produce excess paint noise on the edges, affecting the quality of the painted lines. In addition, some existing road marking equipment is not convenient for protecting the painted road lines. The surface of the freshly painted lines is not dry, and during the drying process, some environmental dust may be absorbed on the surface, affecting the clarity of the line surface.

[0003] Therefore, it is necessary to design an intelligent line marking and layout robot for traffic operations to address the above problems. Summary of the Invention

The rotating pressure cylinder 163 applies paint to the surface of the printed lines, forming a protective film on the surface of the printed lines. Furthermore, the rotation and pressing of the pressure cylinder 163 allows the lines to be printed more closely onto the road surface, improving the quality of the printed lines. Meanwhile, as the pressure cylinder 163 rotates, under the transmission action of the transmission disc 17 and the transmission belt 18, it can control the corresponding rotation of the drive bevel gear 19.
