Bridge and road spraying device

Abstract

The invention belongs to the technical field of road and bridge surface spraying, and particularly relates to a bridge and road spraying device which comprises a base, a pushing handle, a machining unit, a walking unit, a spraying unit and a controller. The spraying unit comprises a supporting rod, a roller and a first spring; the upper surface of the supporting rod is fixedly connected with a mounting plate; the upper surface of the mounting plate is fixedly connected with a copper pipe; a sliding column is connected in the copper pipe in a sliding manner; a circular ring is mounted on the surface of an inner ring above the copper pipe; the upper end of the sliding column penetrates through the ring and extends out of the upper end of the copper pipe; a plurality of second springs are uniformly and fixedly connected to the lower surface of the circular ring; the upper end of the sliding column is fixedly connected with a pressurizing device; the lower surface of the pressurizing device is fixedly connected with a paint containing cavity; and a plurality of spray heads are uniformly and fixedly connected to the lower surface of the paint containing cavity; The device is simple in structure, and the problems that in the spraying process of a spraying device in the prior art, due to the fact that the road surface is not absolutely flat, a paint spraying vehicle shakes during paint spraying, the edge of sprayed paint is irregular, and the road attractiveness is affected can be solved.

Description

technical field [0001] The invention belongs to the technical field of road and bridge surface spraying, in particular to a bridge road spraying device. Background technique [0002] Road bridges are generally composed of subgrades, road surfaces, bridges, tunnel engineering and traffic engineering facilities. The basic alignment of road planes is straight lines, circular curves and cycloids. [0003] Road markings: hot-melt markings, normal temperature cold paint markings, colored anti-slip markings, oscillating anti-slip reflective markings and preformed markings, also known as road markings, refer to markings on the road surface with lines, arrows, Text, facade markings, protruding road signs and outline signs, etc., convey traffic information such as guidance, restrictions, and warnings to traffic participants. Their function is to control and guide traffic. They can be used in conjunction with signs or alone. Lines are now one of the most widely used marking types for ...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, the spraying device used to solve the road marking on the road bridge construction surface in the prior art is generally push-pull to spray the road surface, and Because the road surface is not absolutely flat, the paint sprayer shakes when spraying paint, resulting in irregular edges of the sprayed paint, which affects the appearance of the road. At the same time, the distribution of the sprayed paint is not uniform, which will affect its service life. A bridge road spraying device proposed by the invention
