Description

Technical Field

[0001] This utility model relates to the field of road marking technology, and in particular to a marking device for highway construction. Background Technology

[0002] In the field of highway construction and maintenance, road markings are crucial facilities for improving road safety and guiding traffic flow. Their functions include lane division, indicating driving direction, and warning of dangerous areas, directly impacting driver recognition efficiency and the incidence of traffic accidents. However, existing road marking construction techniques still have significant shortcomings, necessitating structural innovation to address the following issues: Blurring of marking edges caused by splash diffusion: Road surface contamination and lane marking distortion: During the spraying process, paint splashes to both sides due to pressure, contaminating the road surface and causing rough and inconsistent lane marking boundaries. This not only affects aesthetics but also leads to drivers misjudging lane positions, posing a significant safety hazard, especially at night or in rainy or foggy weather. Therefore, a new lane marking device for highway construction is proposed to solve these problems. Utility Model Content

The bottom surface of the retaining wall is movably connected to the ground (i.e., in direct contact with the road surface), and the width of the retaining wall is greater than the width of the slider, covering both sides of the nozzle to prevent splashing. The two bottom corners of the retaining wall are chamfered to facilitate sliding over obstacles. Fixed plates are fixedly connected to both sides of the pipe, and springs are fixedly connected between the bottom surface of the fixed plates and the top surface of the slider. At least two springs are provided above the slider (e.g., two springs on each side) to provide elastic support. The fixed plates are connected to the pipe by welding to ensure a robust structure.

[0017] The retaining walls are located on both sides of the nozzles, with fixed spacing to ensure consistent marking width. The overall component layout is compact, with the tank, pump, and nozzles forming a continuous passage through piping.

[0026] Example 1: The top of the feed inlet 7 is detachably connected to a cover, and the stirring blade on the output end of the geared motor 6 is located in the tank body 5. The pipe 9 is welded to the fixing plate 14, and the guide sleeve 11 is made of stainless steel. The baffle wall 13 is located on both sides of the nozzle 10, and the width of the baffle wall 13 is greater than the width of the slider 12. At least two springs 15 are provided above the slider 12.

[0027] Example 2: This device is specifically designed for highway construction, specifically for marking and marking road surfaces. The device is manually propelled by workers. Marking material, such as cold paint, is added to the tank 5 through the inlet 7. The geared motor 6 and pump 8 are connected to mains power. When the geared motor 6 is operating, its main shaft's stirring blades mix the material. The pump 8 pumps the material out of the tank 5, through the pipe 9, and finally sprays it onto the road surface from the nozzle 10. Combined with the pushing mechanism, this forms road markings of a certain width.

[0028] Device Composition: The main body of the device is a trolley 1, which adopts a front-wheel steering and rear-wheel moving layout. Steering wheels 2 are installed at the front end of the bottom surface of the trolley 1, and moving wheels 3 are installed at the rear end of the bottom surface of the trolley 1, which facilitates workers to control the direction and push the device. A handle 4 is fixedly connected to the edge of the top surface of the trolley 1 for workers to grip.

[0029] A stainless steel tank 5, made of stainless steel, is fixedly connected to the top of a trolley 1 and is used to store marking materials (such as cold paint). A geared motor 6 is mounted on the top of the tank 5, and is vertically mounted to ensure the stability of the main shaft. A stirring blade is fixedly connected to the output end of the geared motor 6, and the stirring blade is located inside the tank 5 for mixing the materials. A feed inlet 7 is fixedly connected to the top of the tank 5, and a detachable cover is attached to the top of the feed inlet 7 for easy addition or sealing of materials.

[0030] A pump 8 is fixedly connected to the top of the cart 1. The input end of the pump 8 is connected to the tank 5 (specifically, the discharge port of the tank 5) via a pipe for drawing raw materials. The output end of the pump 8 is fixedly connected to a pipe 9, which is a rigid pipe to ensure stable spray direction. The end of the pipe 9 is fixedly connected to a nozzle 10, through which the spray material is sprayed onto the road surface.

[0031] The nozzle 10 is symmetrically and fixedly connected to guide sleeves 11 on both sides. The guide sleeves 11 are made of stainless steel and provide wear-resistant guidance. A slider 12 (which can slide up and down) is movably connected inside the guide sleeve 11. A retaining wall 13 is fixedly connected to the bottom of the slider 12. The bottom surface of the retaining wall 13 is movably connected to the ground (i.e., in direct contact with the road surface). The width of the retaining wall 13 is greater than the width of the slider 12, covering both sides of the nozzle 10 to prevent splashing. The two bottom corners of the retaining wall 13 are chamfered to facilitate sliding over obstacles. Fixing plates 14 are fixedly connected to both sides of the pipe 9. Springs 15 are fixedly connected between the bottom surface of the fixing plates 14 and the top surface of the slider 12. At least two springs 15 are provided above the slider 12 (e.g., two springs on each side) to provide elastic support. The fixing plates 14 are connected to the pipe 9 by welding to ensure a robust structure.

[0032] The retaining walls 13 are located on both sides of the nozzles 10 with a fixed spacing to ensure consistent marking width. The overall component layout is compact, with the tank 5, pump 8, and nozzles 10 forming a continuous passage through pipes 9.

[0033] The working principle of this utility model is as follows: When in use, the worker pushes the cart 1 across the road using the handle 4. The steering wheels 2 and the moving wheels 3 support the cart 1, enabling smooth movement. Marking material (such as cold paint or hot melt material) is added to the tank 5 through the inlet 7. Once the tank 5 is full, the lid is tightened. The geared motor 6, connected to mains power, drives the stirring blades on the main shaft to rotate within the tank 5, continuously stirring the material to ensure uniform mixing and fluidity. Simultaneously, the pump 8, connected to mains power, draws material from the input end of the tank 5, pressurizes it, and delivers it to the nozzle 10 through the pipe 9. The nozzle 10 sprays the material onto the road surface at a certain pressure and width, forming continuous markings.

[0034] The core working principle of this device lies in the splash protection and obstacle-crossing mechanism of the floating barrier structure: Splash protection mechanism: During the spraying process of nozzle 10, baffles 13 are installed on both sides of nozzle 10 at fixed intervals (e.g., 5-10 cm). The bottom surface of baffles 13 is movably connected to the ground. Because the width of baffles 13 is greater than the width of slider 12, it conforms to the road surface to form a physical barrier, preventing material from splashing to both sides. This ensures that the spray can only be sprayed forward, guaranteeing sharp and aesthetically pleasing marking edges and preventing contamination of other areas of the road surface. For example, when the spray is ejected, baffles 13 directly bear any lateral force, preventing scattered spraying.

[0035] Automatic obstacle-crossing mechanism: If an obstacle (such as a protruding stone or depression) appears on the road surface during advancement, the retaining wall 13 can float up and down to absorb the impact. Specifically, the retaining wall 13, under the resistance of the ground, pushes the slider 12 to slide within the guide sleeve 11 (the guide sleeve 11 provides guidance) and compresses the spring 15. The elasticity of the spring 15 allows the retaining wall 13 to rise or fall instantaneously, and the chamfered design facilitates sliding over obstacles. After compression, the spring 15 automatically resets, ensuring that the retaining wall 13 quickly returns to its original position and conforms to the road surface, without affecting the continuity of the road markings. This mechanism ensures that the device can work stably on undulating road surfaces, improving reliability and adaptability.

[0036] Compared with the prior art, the present invention has the following advantages: This road marking device is constructed using a combination of guide sleeve 11, slider 12, retaining wall 13, fixing plate 14, and spring 15. Floating retaining walls 13 are installed on both sides of the nozzle 10. The spacing between the retaining walls 13 is fixed, and the retaining walls 13 move with the device. The retaining walls 13 prevent the spray material from splashing to both sides, ensuring the aesthetics of the markings, and also prevent excess spray material from contaminating other parts of the road surface. The retaining walls 13 are not fixed and can overcome road obstacles. At this time, the spring 15 is compressed to adapt to road surface undulations.
