Accurate-positioning road marking device

Abstract

The invention relates to an accurate-positioning road marking device which comprises a frame, a wheel train, a driving device, a marking cavity, a transverse cleaning assembly and a laser positioner, the wheel train is arranged at the bottom of the frame, a handle is fixedly arranged at the position, close to the edge, of the frame, the driving device is fixedly arranged on the frame, the driving device is used for driving the wheel train to rotate and driving the transverse cleaning assembly to transversely clean a road, a material preparation barrel and a heating cavity are fixedly arranged on the vehicle frame, the marking cavity is fixedly formed in the bottom of the vehicle frame, and the heating cavity provides paint for the marking cavity through a hose, and a laser positioning device is fixedly arranged on the frame. According to the road marking device, dust in a marking area is swept to the two sides of the marking area through the transverse cleaning assembly, so that it is guaranteed that a hot-melt coating road is firmly and reliably bonded, and dust rising to the hot-melt coating is reduced.

Description

technical field [0001] The invention relates to the technical field of a road marking device with precise positioning, in particular to a road marking device with precise positioning. Background technique [0002] Marking machine, a road construction machine that is widely used in roads, high-grade highways, parking lots, squares and runways to draw different restrictions, guidelines and warnings on the flat ground. With its fast, efficient, accurate and other advantages, the marking machine has played a huge role in urban planning and road construction, saving the construction period and economic investment of road construction to the greatest extent. [0003] At present, the existing simple scribing machine has insufficient positioning, which makes the scribing difficult to achieve the expected effect and low work efficiency; and in order to ensure that the hot-melt coating can be in contact with the clean ground, the hot-melt coating has a good effect on the ground. The ...

[0003] At present, the existing simple scribing machine has insufficient positioning, which makes the scribing difficult to achieve the expected effect and low work efficiency; and in order to ensure that the hot-melt coating can be in contact with the clean ground, the hot-melt coating has a good effect on the ground. The adhesion effect needs to keep the road surface clean. The existing marking machine will sweep the dust to the marking area when cleaning the road surface, which will cause the hot melt paint to mix with the dust and cause poor adhesion; due to the uneven heating in the heating chamber Phenomenon will lead to partial solidification of the internal slurry, which will affect the uniformity of the slurry
