A marking vehicle for three-lane roads

Abstract

The invention relates to a marking vehicle used for a three-lane road. The marking vehicle mainly comprises a vehicle body. A central frame is arranged on the vehicle body. A No.1 sliding holder and a No.2 sliding holder are installed on the central frame. The No.1 sliding holder and the No.2 sliding holder are in sliding connection with a No.1 bearing holder and a No.2 bearing holder respectively. A No.1 rack is installed on the No.1 bearing holder and a No.2 rack is installed on the No.2 bearing holder. The No.1 rack is engaged to a No.1 gear. The No.1 gear is connected with a No.2 gear and transmission gears. The No.2 gear is engaged to the No.2 rack. Two idle gears are arranged between the two transmission gears. Plugging covers are arranged at the lower end of the No.1 bearing holder and the lower end of the No.2 bearing holder respectively. An opening is arranged beside each plugging cover. The upper end of each plugging cover is pressed against a bar-shaped pipe. The bar-shaped pipe is connected with a raw material storage box. Annular teeth are arranged at the circumferential outer end of each plugging cover. The annular teeth are engaged to an auxiliary gear. The marking vehicle has functions of ensuring marking length and marking interval constant and marking of roads with different lane widths.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a marking vehicle for three-lane roads. Background technique [0002] Generally speaking, after the construction of the main part of the highway, it is necessary to divide the lanes on the highway. Among the various lane divisions, the planning of the single white line is the most difficult, because when marking the lines, people not only need to ensure The length of each single white line in the length direction is constant and the distance between two adjacent single white lines is constant. In the width direction of the road surface, the width of each lane is equal and the start and end ends of the single white line are flush. Although some construction machinery can do this, when the condition of the road to be marked changes, the width of the lane will often change. For example, the three-lane road to be marked is compared to the original road. When the lane width of th...

[0002] Generally speaking, after the construction of the main part of the highway, it is necessary to divide the lanes on the highway. Among the various lane divisions, the planning of the single white line is the most difficult, because when marking the lines, people not only need to ensure The length of each single white line in the length direction is constant and the distance between two adjacent single white lines is constant. In the width direction of the road surface, the width of each lane is equal and the start and end ends of the single white line are flush. Although some construction machinery can do this, when the condition of the road to be marked changes, the width of the lane will often change. For example, the three-lane road to be marked is compared to the original road. When the lane width of the highway marked by machinery is increased by X width, the single white line between its first lane and second lane is equivalent to shifting X distance to the side, and the single white line between its second lane and third lane The white line is equivalent to a 2X distance to the side, and the single white line of the same lane and the opposite lane needs to be adjusted in this way, and traditional construction machinery is often not suitable for this because it is difficult to adapt to the change of lane width. lane marking job
