Description

Technical Field

[0001] This invention relates to the field of road marking technology, and in particular to a multifunctional hot-melt road marking vehicle. Background Technology

[0002] Road marking is a crucial part of traffic infrastructure construction and maintenance. It plays a key role in regulating vehicle traffic, ensuring traffic safety, and improving road efficiency. Traditional road marking methods, such as manual hand-held spray guns or simple marking equipment, have many drawbacks. Manual marking is inefficient, and it is difficult to guarantee uniform marking quality. The straightness, width, and other precision indicators of the lines are prone to deviation. Some early marking vehicles also have limitations in function and performance. For example, the heating method is not efficient enough, resulting in uneven melting of the paint, which affects the marking quality. They also cannot meet the requirements of high-speed operation.

[0003] With the continuous development of transportation, higher demands have been placed on the quality and efficiency of road marking. Hot-melt marking technology has emerged and is gradually being widely used. Hot-melt marking features vibrant colors, good wear resistance, and reflective properties, maintaining clear visibility under various adverse weather and road conditions, effectively improving road safety and visibility. However, traditional hot-melt marking equipment has some shortcomings in its structural design and working principle, limiting its application in highway marking operations: First, existing marking machinery on the market requires a short timeframe to complete the required marking work, necessitating the cooperation of raw material transport vehicles, melting vehicles, and marking equipment. Second, traditional marking equipment requires manual labor using simple marking devices, resulting in low efficiency and inconsistent marking quality, with deviations easily occurring in the straightness and width of lines. While ride-on marking equipment solves the shortcomings of traditional equipment, it presents the problem of slow relocation, requiring trailers for transport, increasing labor and equipment costs.

[0004] To address the aforementioned problems, a multifunctional hot-melt marking machine is proposed. Summary of the Invention

At the same time, traditional line marking equipment requires manual use of simple line marking equipment, which has many drawbacks such as low efficiency of manual line marking, difficulty in ensuring uniform line marking quality, and easy deviation of accuracy indicators such as straightness and width of lines. Although the ride-on line marking equipment solves the drawbacks of traditional equipment, it cannot be quickly transferred to another site, and the transfer requires a trailer, which increases the labor and equipment costs.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a multi-functional hot-melt marking vehicle. Through an integrated melting system within the vehicle, the vehicle moves forward, and marking operations can be performed by operating the corresponding function buttons on the control panel according to the marking position requirements. The powdered hot-melt material enters the vessel body of the vessel assembly, where it exchanges heat with the flue between the inner and outer vessels and the high-temperature heat transfer oil in the bottom heat-conducting jacket of the vessel body. This transforms the powdered hot-melt material into a marking-ready state, which is then fed into a pump. The marked hot-melt material is then transported through a filter to the double-sided marking system for marking. This efficient circulation heating of the powdered hot-melt material greatly improves heating efficiency and ensures the continuity of the marking operation. The feed pipe directs the powdered hot-melt material towards the marking system. The line-making mechanism delivers hot-melt material, enabling high-speed, efficient, and safe road marking construction. It avoids road closures and disruptions to normal traffic, and is highly integrated, adapting to large-scale, long-term road marking tasks. This improves construction convenience, reduces personnel and equipment requirements, lowers the intensity and difficulty of manual operation, and enhances automation and overall quality. It addresses shortcomings in the structural design and working principle of existing hot-melt road marking equipment. Currently available road marking machinery requires the coordinated operation of raw material transport vehicles, melting vehicles, and marking equipment to complete a certain amount of marking work within a short timeframe, due to project time constraints.

[0017] 2. This invention provides a multi-functional hot-melt road marking vehicle. As the vehicle moves forward to begin marking operations, the marking mechanism evenly coats the road with hot-melt material. High-temperature heat-conducting oil is injected into the heat-conducting ring cavity within the wall of the conveying pipe through a heat-conducting oil pipe, thereby heating the hot-melt material in the conveying pipe. This ensures the hot-melt material entering the marking mechanism is kept warm and maintains good fluidity. During marking operations, the valve of the glass bead storage hopper opens, and glass beads begin to be sprayed. By adjusting the adjusting shaft and adjusting plate of the glass bead spreading device, the spreading amount and width of the glass beads are adjusted to achieve the best marking quality with the optimal reflectivity. This solves the problem that existing hot-melt road marking equipment requires manual operation with simple marking devices, resulting in low efficiency and difficulty in ensuring uniform marking quality.

[0032] Working principle: When marking lines, pull out the connecting pin 25 and flip the guide rod 22 forward and downward so that the front end of the guide rod 22 faces forward and downward. The guide wheel 26 rolls and supports on the ground, while the lower end of the guide needle 23 slides and supports on the ground. The driver can then drive the highway marking vehicle along the pre-marked lines on the ground according to the guide needle 23. Start the engine 31, and the front drive shaft 34 drives the transfer case 33 to rotate. Operate the relevant buttons to switch the vehicle to hydraulic driving mode. The transfer case 33 then transmits power to the hydraulic pump 41. The hydraulic pump 41 pumps the hydraulic oil in the hydraulic oil tank 42 through the hydraulic oil circuit and the hydraulic oil filter 44 to the associated motors, cylinders and hydraulic valve groups 45. When a certain action function needs to be achieved, the associated hydraulic valve group 45 channel is opened through the electrical control button, and the associated motor or telescopic cylinder is activated, thereby making the related action module run.When the forward module is activated, the transfer case 33 transmits power to the rear axle drive shaft 35, propelling the vehicle forward. Based on the marking position requirements, the corresponding function buttons on the control panel are operated to perform the marking operation. The powdered hot melt material enters the vessel 511 of the vessel mixing assembly 51. The powdered hot melt material exchanges heat with the flue between the vessel 511 and the high-temperature heat transfer oil in the bottom heat-conducting jacket of the vessel 511, transforming it into hot melt material suitable for marking. This material then enters the feed pump 532 and is conveyed through the feed pipe 531, passing through a filter and transported to the double-sided marking system 6 for marking. This process... The efficient circulating heating of the powdered hot melt material greatly improves heating efficiency and ensures the continuity of the marking operation. The hot melt materials in the two reactor mixing assemblies 51 can be connected. After the molten material reaches the marking state, when the marking operation begins, the first valve 534 is opened, and the telescopic function of the marking device 61 on the controller is activated. This controls the swing arm assembly to rotate around the first hinge, thereby maximizing the movement of the lower parts of the swing arm assembly. This causes the marking mechanism 612 connected to the lower part of the swing arm assembly to move to the predetermined position, controlling the action of the marking device's actuation valve 614, and the material conveying pipe 5... 31. Hot melt material is fed to the marking mechanism 612. As the vehicle moves forward, the marking operation begins. The marking mechanism 612 evenly coats the road with the hot melt material. High-temperature heat transfer oil is injected into the heat transfer ring cavity inside the conveying pipe 531 through the heat transfer oil pipe, thereby heating the hot melt material in the conveying pipe 531 to ensure that the hot melt material entering the marking mechanism 612 is kept at a constant temperature and maintains good fluidity. When the marking operation begins, the valve of the glass bead storage bin 71 is opened, and the glass beads begin to be sprayed. By adjusting the adjusting shaft and adjusting plate of the glass bead spreading device 73, the spreading amount and spreading width of the glass beads are adjusted to achieve optimal results. The quality of the line markings is determined by the optical coefficient. After the air compressor start button on the control panel is pressed, the hydraulic control valve channel of the upper engine 31 opens, and the air compressor operates through the power transmitted from the upper engine 31. The air compressor produces compressed air which enters the air tank for pressure storage. Each air-using component draws compressed air from the air tank as needed. When a function key of an air-using mechanism on the control panel is activated, the compressed air from the air tank passes through the corresponding pneumatic solenoid valve, pressure gauge, pneumatic triplet, pressure regulating valve, valve, etc., to the corresponding cylinder or other air-using mechanism. The cylinder or other air-using mechanism then actuates to achieve the corresponding function.

[0033] When the marking vehicle needs to be started, turn on the main power switch and follow the normal vehicle start-up procedure to realize the normal driving function of the vehicle. When marking work is being carried out, the hydraulic driving mode can be activated by operating the corresponding buttons in the cab 13. After activating the hydraulic driving mode, the corresponding function operation can be performed by operating the relevant function keys on the control panel. When it is necessary to transfer between sites during the marking work, the transfer function can be activated in the cab 13 to realize the heat preservation and heating function of the hot melt material during the transfer period.
