Road and bridge marking device

Abstract

The invention provides a road and bridge marking device, and mainly relates to the field of road equipment. The road and bridge marking device comprises a vehicle body, a wheel train is arranged at the bottom of the vehicle body. A high-pressure water system, a hot-melt coating kettle and a fuel heating system are arranged at the top of the vehicle body; a sweeper, a friction device, a high-pressure water spray head, a dryer, a hot melt coating spray head and an air cooler are sequentially arranged at the bottom of the vehicle body from the front end to the rear end, the high-pressure water spray head is matched with the high-pressure water system, and the dryer and the hot melt coating spray head are both matched with the fuel heating system. The road and bridge marking device has the beneficial effects that the road cleaning procedure can be added before hot-melting marking, a clean and tidy road surface environment is provided for road hot-melting marking, and therefore the attachment effect of hot-melting marks on the road surface is better, and the service life is longer.

Description

technical field [0001] The invention mainly relates to the field of road equipment, in particular to a marking device for roads and bridges. Background technique [0002] Road markings are signs set on the road to guide and instruct vehicles. Road markings are usually divided into hot-melt markings and normal temperature cold paint markings. Among them, hot-melting markings have better wear resistance and are used With longer life and lower cost, it is currently the most commonly used road marking method. Hot-melt marking has high requirements on the cleanliness of the road surface. If the road is marked with dust and moisture, there will be more impurities between the hot-melt paint and the road surface when marking the road, making the hot-melt paint If the bond with the road surface is not firm, it is extremely easy to cause the hot-melt marking line to fall off and affect the quality of the marking line. [0003] At present, the debris on the road surface is mainly red...

AI Technical Summary

Problems solved by technology

Hot-melt marking has high requirements on the cleanliness of the road surface. If the road is marked with dust and moisture, there will be more impurities between the hot-melt paint and the road surface when marking the road, making the hot-melt paint The bonding with the road surface is not firm, it is extremely easy to cause the hot-melt marking line to fall off, affecting the quality of the marking line

[0003] At present, the debris on the road surface is mainly reduced by cleaning before marking. However, for roads that have been in service for a long time, it is difficult to ensure that the debris on the road surface can be completely cleaned, which will affect the heat dissipation. The adhesion effect of the melting line shortens the service life of the road line
