Description

Technical Field

[0001] This utility model relates to the field of highway marking technology, and more specifically, to a highway construction marking device. Background Technology

[0002] In the field of road construction and maintenance, road marking machines, as key construction equipment, are widely used in marking operations on highways, urban roads, parking lots, and other areas. However, in actual operation, workers often face the problem of obstructed vision, especially under complex and changing road conditions and lighting conditions, making it difficult to accurately position and calibrate the marking tools. This directly affects the accuracy and efficiency of the marking operation. In addition, existing road marking machines often have certain limitations in their functional design, especially in the adjustment of line thickness, making it difficult to meet diverse construction needs, thus limiting the practicality and flexibility of the equipment.

[0003] Chinese patent CN 220352594 U proposes an improved highway marking construction device that attempts to adjust the marking width by adjusting the distance between two inclined plates using bolts. While this design offers some possibility of width adjustment, its traditional threaded connection method has significant drawbacks. Specifically, after prolonged use, the threaded connection is prone to wear, leading to stripping and affecting adjustment accuracy and stability. More seriously, the inner inclined plate may accidentally detach from the bolt end, increasing maintenance costs and directly threatening safety during construction.

[0004] Furthermore, this patented design has another significant technical limitation. Because the nozzle is fixed below the equipment and lacks an intuitive width indication system, operators often find it difficult to immediately and accurately judge the actual width of the sprayed material after adjusting the spacing of the ramps to change the line width. When manually pushing the equipment to perform line marking operations, this uncertainty can easily lead to directional deviation, causing the drawn lines to be curved or not straight, seriously affecting the quality and visual effect of the markings.

[0005] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to solve the problems mentioned in the background art and to propose a highway construction marking device.

The guide plate slides with the through portion of the connecting plate. Each guide plate is fixedly connected to a vertically upward-facing support plate on its outer side. The top of the support plate is located above the mounting plate.

[0014] Two bidirectional lead screws are symmetrically fixedly connected between the front and rear sides of the two support plates. The threads on both sides of the bidirectional lead screws are arranged in opposite directions. The center of the bidirectional lead screw is broken.
