AI Technical Summary

Problems solved by technology

However, this scheme also has relatively large technical problems. Due to the high viscosity of asphalt in asphalt concrete, it is easy to stick to the knife during the cutting process, which affects the subsequent milling efficiency, especially for the scheme that only cuts a small amount of asphalt concrete. Solution requires frequent downtime to clean tools
There is also a solution to use grinding wheels for grinding, but this solution is less efficient

Abstract

The invention provides a pavement marker line removing device. The pavement marker line removing device comprises a swing frame, a planing and milling roller installed on the swing frame, a driving device used for driving the planing and milling roller to rotate and a swing frame lifting device used for adjusting feeding of the planing and milling roller. One end of the swing frame is pivoted to awalking vehicle body, the other end of the swing frame is provided with the rotatable planing and milling roller, and the axis of the planing and milling roller is parallel to the ground. A planing and milling driving motor is arranged on the walking vehicle body or the swing frame and is connected with the planing and milling roller through a transmission mechanism. The swing frame lifting device is arranged between the walking vehicle body and the swing frame. By means of the scheme in which a refrigerant nozzle sprays low-temperature airflow to embrittle a pavement marker, planing, millingand removing are facilitated, knife sticking in the construction process is avoided, and the removing efficiency can be further greatly improved through a multi-saw-blade roller structure. The devicecan be used for removing pavement marker lines, and can also be used for removing defects of asphalt concrete pavements, such as bulges, indentations and cracks.

Description

technical field [0001] The invention relates to the field of asphalt concrete road surface construction, in particular to a device for removing road marking lines. Background technique [0002] Asphalt concrete pavement is a very widely used road surface. The pavement is usually provided with road marking lines. After a period of use, the pavement marking lines are easy to wear or have modifications. The marking lines often need to be repaired or changed. The trimming of the existing asphalt concrete pavement for municipal engineering is generally carried out manually. At first, the damaged part of the asphalt pavement is chiseled out together with the surrounding parts by the staff using tools such as rakes and chisels, and the chiseled part is cleaned, and then Lay asphalt concrete manually, then use hot pressing device to melt and smooth the asphalt, and finally wait for the asphalt to dry; however, the above steps need to be carried out manually and require the cooperati...
