[0001] This utility model relates to the field of road reconstruction technology, and in particular to a road marking mechanism for the reconstruction of old residential areas. Background Technology
[0002] Road renovation in older residential areas typically includes updating and repairing road infrastructure, with road marking being a crucial component. Clear and standardized road markings not only improve the appearance of the road but also effectively guide traffic and enhance residents' safety. Therefore, reasonable and accurate road marking is an important task in renovation projects.
[0003] In existing technologies, common road marking tools include hand-operated carts. These devices are typically equipped with spraying units, and the markings are applied by manually pushing the cart along the road. The carts are relatively simple in structure, easy to operate, and suitable for small-scale road construction. This method allows operators to precisely control the width and length of the markings, and the flexibility and convenience of the equipment have led to its widespread use in many old residential area renovation projects.
[0004] However, existing line marking tools still have certain limitations when facing different marking requirements. When different road marking requirements need to be met and different specifications of spray plates need to be replaced, the adjustment process of traditional tools is relatively cumbersome, or the road is repeatedly sprayed, which is inefficient. Therefore, a line marking mechanism for the renovation of old residential roads is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a road marking mechanism for the renovation of old residential roads, aiming to improve the problem that the adjustment process of traditional tools is relatively cumbersome when facing different road marking needs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Multiple fixing rods evenly distributed in a straight line are fixed to the side of the movable plate near the spray plate. Limiting components are provided on both the left and right sides of the movable plate.
[0009] As a further description of the above technical solution:
[0010] The cleaning mechanism includes an electric push rod 2, which is fixed inside the trolley. One end of the electric push rod 2 is fixed with a sliding plate, the bottom of the sliding plate is fixed with a connecting rod, one side of the connecting rod is fixed with a mounting plate, a scraper is slidably connected inside the mounting plate, and a support assembly is provided inside the mounting plate.
[0011] As a further description of the above technical solution:
[0012] The limiting component includes a slider, which is fixed to one side of the movable plate, and a support rod slides inside the slider;
[0013] As a further description of the above technical solution:
[0014] The support assembly includes a damping rod, which is fixed to the scraper on the side near the mounting plate. Limit blocks are fixed on both the front and rear sides of the scraper, and limit grooves are formed on both the front and rear sides of the interior of the mounting plate.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a road marking mechanism for the renovation of old residential roads, including a handcart 1, which is a road marking cart used for marking roads in the residential area. A storage box 2 is installed on the top center of the handcart 1 for storing marking materials. A handle 4 is installed on the top rear of the handcart 1 for easy movement by workers. A toolbox 11 is installed on the top front of the handcart 1, and a spraying plate 6 is installed in the middle of the handcart 1. The toolbox 11 is used to hold different types of spraying plates 6, thereby enabling the marking of different types of road lines. Two electric pumps 3 are installed on the side of the storage box 2 near the toolbox 11. The end of the electric pump 3 away from the storage box 2 is fixed to the spray plate 6 through the conveying pipe 12. The electric pump 3 is used to draw the raw material inside the storage box 2 and convey the raw material to the spray plate 6 through the conveying pipe 12, so that the spray plate 6 sprays out the raw material to mark the lines. The bottom of the handcart 1 is equipped with multiple wheels 5 evenly distributed in a rectangular array. The wheels 5 are part of the handcart 1, which enables the handcart 1 to move normally. The middle of the inside of the handcart 1 is provided with a fixing mechanism 7 and a cleaning mechanism 9.
[0037] Reference Figure 2 and Figure 7The fixing mechanism 7 includes an electric push rod 701, which is fixed inside the handcart 1. A cross plate 702 is fixed to the bottom of the electric push rod 701. The electric push rod 701 is used to control the movement of the cross plate 702. The electric push rod 701 is a short-stroke electric push rod, model La12. Rotary rods 703 are rotatably connected to both ends of the cross plate 702. A connecting plate 704 is rotatably connected to the outer circumference of the end of the rotary rod 703 away from the cross plate 702. The rotary rod 703 is used to connect the cross plate 702 and the connecting plate 704. When the cross plate 702 moves vertically, the rotary rod 703 will generate different angles according to the rotation direction of the cross plate 702. And rotational movements in different directions. When the rotating rod 703 rotates, it will drive the connecting plate 704 to move. A movable plate 705 is fixed at the bottom of the connecting plate 704. Multiple fixed rods 706 are fixed on the side of the movable plate 705 near the spray plate 6. The movable plate 705 is fixed to the connecting plate 704. When the connecting plate 704 moves, it will drive the movable plate 705 to move together. The fixed rods 706 will move together with the movable plate 705. By contacting and separating the fixed rods 706 from the spray plate 6, the spray plate 6 can be fixed and disassembled accordingly. Limiting components 8 are provided on both the left and right sides of the movable plate 705.
[0038] Reference Figure 5 - Figure 6 The cleaning mechanism 9 includes an electric push rod 901, which is fixed inside the trolley 1. A sliding plate 902 is fixed to one end of the electric push rod 901. The electric push rod 901 is the same model as the electric push rod 701, both being La12. The telescopic end of the electric push rod 901 is connected to the sliding plate 902. When the electric push rod 901 is activated, it will drive the sliding plate 902 to move forward and backward accordingly. The sliding plate 902 is slidably connected inside the trolley 1. A connecting rod 903 is fixed to the bottom of the sliding plate 902, and a mounting plate 904 is fixed to one side of the connecting rod 903. The connecting rod 903 is used to connect the sliding plate 902. When the slide plate 902 moves, the mounting plate 904 is moved by the connecting rod 903. A scraper 905 is slidably connected inside the mounting plate 904. The side of the scraper 905 away from the mounting plate 904 is slidably connected to the side of the spray plate 6 away from the trolley 1. The scraper 905 is made of silicone material and is in contact with the nozzle of the spray plate 6. When the mounting plate 904 moves, the scraper 905 moves along the nozzle of the spray plate 6 to scrape off the excess material exposed outside the nozzle, so as to avoid the excess material solidifying and reducing the marking effect. A support component 10 is provided inside the mounting plate 904.
[0039] Reference Figure 7The limiting component 8 includes a slider 801, which is fixed to one side of the movable plate 705. A support rod 802 slides inside the slider 801 and is fixed inside the trolley 1. The support rod 802 is used to guide the slider 801 to move. The slider 801 is connected to the movable plate 705. When the movable plate 705 moves, the slider 801 will move along the support rod 802, thereby making the movable plate 705 move horizontally in a straight line.
[0040] Reference Figure 6 The support assembly 10 includes a damping rod 1001, which is fixed to the side of the scraper 905 near the mounting plate 904. The end of the damping rod 1001 away from the scraper 905 is fixed inside the mounting plate 904. The damping rod 1001 connects the mounting plate 904 and the scraper 905 and provides support for the mounting plate 904. Limiting blocks 1002 are fixed on both the front and rear sides of the scraper 905. Limiting grooves 1003 are opened on both the front and rear sides of the interior of the mounting plate 904. The limiting blocks 1002 are slidably connected inside the limiting grooves 1003. The limiting blocks 1002 move together with the scraper 905, while the limiting grooves 1003 limit the range of movement of the limiting blocks 1002 to prevent the damping rod 1001 from exerting too much reaction force on the scraper 905, causing the scraper 905 to slide out of the mounting plate 904.
[0041] Working principle: When marking roads, the prepared raw materials are first transported to the storage bin 2. Then, the marking trolley is moved to the designated road. Then, the electric pump 3 is started according to the pre-designed road line. The electric pump 3 draws the raw materials from the storage bin 2 and transports them to the spray plate 6 through the conveying pipe 12. The raw materials are then sprayed onto the road surface through the spray plate 6. After that, the trolley can be pushed to continuously mark the lines.
[0042] When switching to stop the material delivery and changing the road for marking, the electric push rod 901 must be activated first. The electric push rod 901 controls the movement of the slide plate 902. As the slide plate 902 moves, the connecting rod 903 at the bottom of the slide plate 902 will drive the mounting plate 904 and the scraper 905 to move along the spraying plate 6, scraping off the excess solidified material on the outer periphery of the spraying plate 6 to prevent the re-sprayed material from affecting the newly marked road lines. When the scraper 905 comes into contact with the solidified material on the outer periphery of the spraying plate 6, a force will be generated. The scraper 905 moves into the mounting plate 904. When the scraper 905 moves, it will apply a force to the damping rod 1001, causing the damping rod 1001 to retract and provide a reaction force to the scraper 905. The corresponding limiting block 1002 will also move in the limiting groove 1003 to avoid the damping rod 1001 providing too much reaction force to the scraper 905, which would cause the scraper 905 to collide with the spray plate 6. When it is necessary to draw road lines of different widths, the spray plate 6 of the corresponding size can be replaced.
[0043] First, start the electric push rod 701, causing the electric push rod 701 to move the horizontal plate 702 downward. When the horizontal plate 702 moves downward, the rotating rods 703 at both ends of the horizontal plate 702 will rotate in opposite directions. At this time, the rotation of the rotating rods 703 will cause the connecting plate 704 to move the movable plate 705 horizontally inside the handcart 1. As a result, the multiple fixing rods 706 on the side of the movable plate 705 near the spray plate 6 will separate from the spray plate 6. Then, the conveying pipe 12 can be disassembled and separated from the spray plate 6. After that, take out spray plates 6 of different sizes from the toolbox 11, connect the spray plate 6 to the conveying pipe 12, and start the electric push rod 701 again, causing the electric push rod 701 to move the horizontal plate 702 upward. At this time, the two rotating rods 703 rotate relative to each other, causing the two connecting plates 704 to move the two movable plates 705 towards each other. Then, the two fixing rods 706 contact the spray plate 6, thereby fixing the spray plate 6.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
