Description

Technical Field

[0001] This utility model relates to the field of line marking vehicle technology, specifically to a line marking adjustment mechanism for a line marking vehicle. Background Technology

[0002] Currently, most commercially available parking line marking vehicles rely on manual operation for adjusting line positions. For example, some simple marking devices require operators to frequently get out of the vehicle to manually adjust screws, knobs, and other mechanical parts to change the position of the marking nozzles. This method is extremely inefficient, and human operation is prone to errors, making it difficult to guarantee the accuracy of the marked lines. This results in significant deviations in the straightness and spacing of the drawn lines. Taking parking space marking in a parking lot as an example, traditional methods struggle to ensure that the dimensions of each parking space are precisely consistent, affecting space utilization efficiency and overall aesthetics.

[0003] Some line marking devices with automated adjustment functions use a single motor to drive a lead screw to adjust the position of the line marking nozzle. However, this method can only achieve adjustment in one direction and one mode, and cannot meet the diverse line adjustment needs in complex line marking scenarios. For example, when drawing gradient lines at road curves or multiple parallel lines of different widths and spacings, these devices are often inadequate and cannot flexibly and accurately control the position and trajectory of the line marking nozzle.

[0004] Furthermore, existing line marking equipment has significant shortcomings in measuring and monitoring the marking position. Most equipment lacks effective real-time measurement devices, and operators can only determine the marking position based on experience and simple markings. It is impossible to obtain timely and accurate distance information between the marking nozzle and reference objects such as road edges and existing markings, making it difficult to adjust the marking position in real time according to the actual situation. This results in unstable marking quality, and it is difficult to ensure that the distance between the lines and reference objects meets the standard requirements under different road conditions and operating environments.

[0005] Therefore, it is necessary to provide a line marking adjustment mechanism for a line marking vehicle to solve this problem. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a marking adjustment mechanism for a marking vehicle, which has the advantages of automatic and precise adjustment of the marking position, ensuring marking accuracy and supporting diverse marking needs, and convenient paint can replacement.

[0017] 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.

[0018] like Figures 1 to 4As shown, the present invention provides a line marking adjustment mechanism for a line marking vehicle, comprising a movable frame 1, a battery 2 fixedly connected to the top of the movable frame 1, an inclined surface on the outer shell of the battery 2, a bearing plate 3 fixedly connected to the surface of the inclined surface, a support frame 4 symmetrically fixedly connected to the surface of the bearing plate 3, a lead screw 5 rotatably connected inside the support frame 4 via bearings, and the two lead screws 5 being centrally symmetrically arranged, a servo motor 6 fixedly connected to the surface of the support frame 4, and the output shaft of the servo motor 6 being fixedly connected to the lead screw 5 via a coupling, and a moving block 7 threadedly connected to the surface of the lead screw 5. The support plate 8 is fixedly connected to the outer side of the movable block 7, which is slidably connected to the support plate 3. The bottom of the surface of the support plate 8 is fixedly connected to the control valve 9. The output end of the control valve 9 is connected to the marking spray head 10, and the input end of the control valve 9 is connected to the self-spraying marking paint can 11. The surface of the support plate 8 is symmetrically fixedly connected to the snap-fit ​​block 12, and the snap-fit ​​block 12 snaps into the self-spraying marking paint can 11. The top of the battery 2 is fixedly connected to the support frame 13, and the outer side of the support frame 13 is fixedly connected to the controller 14. The surface of the controller 14 is symmetrically provided with control handles 15, and the control handles 15 are used in conjunction with the control valve 9.

[0019] refer to Figure 1 and Figure 2 The top of the mobile frame 1 is fixedly connected to a storage box 16, and the storage box 16 is located at the center of the top of the mobile frame 1. The top of the storage box 16 has several evenly arranged storage slots, and the top of the storage slots is threadedly connected to a slot cover.

[0020] As a technical optimization of this utility model, the storage box 16 can accommodate multiple spare spray paint cans 11, reducing the time for retrieving materials. At the same time, the storage box 16 is located at the top center of the mobile frame 1, forming a balanced weight with the battery 2, lowering the center of gravity of the vehicle and improving the stability of movement.

[0021] refer to Figure 1 The inner wall of the support frame 4 is symmetrically fixed with a sliding column 17 about the lead screw 5. The surface of the moving block 7 is provided with a sliding opening, and the sliding opening is slidably connected to the sliding column 17.

[0022] As a technical optimization of this utility model, the radial wobble of the lead screw 5 during rotation is limited by the sliding column 17 and the sliding joint of the moving block 7, and the error during the translation of the moving block 7 is reduced, making the scribing lines smoother. At the same time, the sliding column 17 shares the lateral force borne by the lead screw 5, thereby extending the service life of the lead screw 5 and reducing maintenance costs.

[0023] refer to Figure 1 A laser rangefinder 18 is symmetrically fixedly connected to the surface of the support frame 4, and the laser rangefinder 18 is used in conjunction with the support plate 8.

[0024] As a technical optimization of this utility model, the laser rangefinders 18 symmetrically arranged on the surface of the support frame 4 cooperate with the support plate 8. The inner laser rangefinder 18 can accurately measure the lateral displacement of the marking spray head 10 and feed it back to the controller 14 to adjust the servo motor 6 to ensure the movement accuracy. The outer laser rangefinder 18 is aligned with the road edge or existing markings as a reference to ensure the accurate distance between the marking and the reference object. In addition, the two laser rangefinders 18 work together to improve the accuracy and consistency of the marking. With the independent control of the two servo motors 6, it can meet diverse marking needs, reduce manual calibration, and improve efficiency.

[0025] refer to Figure 1 , Figure 3 and Figure 4 The surface of the support plate 8 has a movable opening 19. A positioning block 20 is slidably connected to the surface of the support plate 8. A locking bolt 21 is threadedly connected to the back of the positioning block 20. The locking bolt 21 passes through the movable opening 19 and works in conjunction with it. A locking plate 22 is fixedly connected to the surface of the locking bolt 21 and fits against the support plate 8.

[0026] As a technical optimization of this utility model, by setting up the movable port 19, the positioning block 20, the locking bolt 21 and the locking plate 22, the self-spraying marking paint can 11 can be positioned by using the sliding locking plate 22, and can be adjusted according to the length of the self-spraying marking paint can 11, thereby improving the stability of the device during use.

[0027] refer to Figure 1 The surface of the lead screw 5 is covered with a retractable protective sleeve (not shown), and the two ends of the protective sleeve are fixedly connected to the support frame 4 and the moving block 7, respectively.

[0028] As a technical optimization of this utility model, the retractable protective sleeve isolates dust and paint particles, reducing the failure rate of the lead screw 5 in dusty environments. At the same time, the protective sleeve completely covers the rotating lead screw 5, preventing the operator's clothing or limbs from getting caught in it.

[0029] The working principle and usage process of this utility model are as follows: When using this marking adjustment mechanism, the operator first fixes the self-spraying marking paint can 11 to the support plate 8 through the snap-fit ​​block 12, connects the control valve 9 to the marking spray head 10, turns on the battery 2 to power the equipment, and presets the marking parameters through the controller 14; the laser rangefinders 18 symmetrically fixed on the surface of the support frame 4 start working, with the inner laser rangefinder 18 measuring the moving distance of the support plate 8 in real time to accurately calculate the lateral displacement of the marking spray head 10, and the outer laser rangefinder 18 aligning with the road edge or existing markings as a reference to determine the initial marking benchmark; the servo motor 6 drives the lead screw 5 to rotate, driving the moving block 7. Sliding along the support plate 3, the sliding column 17 restricts the rotational tendency of the moving block 7 to ensure smooth movement, allowing the marking spray head 10 to move to the preset initial position. During this process, the measurement data from the inner laser rangefinder 18 is fed back to the controller 14. If there is a deviation from the preset displacement, the controller 14 automatically adjusts the speed of the servo motor 6 for correction. The operator pushes the moving frame 1 forward and presses the control handle 15 to trigger the solenoid valve. The paint in the self-spraying marking paint tank 11 is adjusted in flow by the control valve 9 and then sprayed out in an atomized state through the marking spray head 10 to form a marking line with adjustable width. The positioning block 20 on the surface of the support plate 8 can slide along the moving port 19. After adjusting to the appropriate position, the locking bolt 21 is tightened to make the marking line more stable. The locking plate 22 fits tightly against the support plate 8, further strengthening the fixation of the marking spray head 10 by increasing friction, preventing displacement due to vibration during operation. When encountering a turn, the controller 14 combines the reference data from the outer laser rangefinder 18 and the displacement measurement results from the inner laser rangefinder 18, dynamically adjusting the speed of the left and right servo motors 6 according to the preset radius of curvature to ensure smooth line transition. When multiple lines need to be drawn, the two servo motors 6 independently drive the lead screw 5, controlling the displacement of the corresponding marking spray head 10 through the inner laser rangefinder 18, achieving parallel marking of different widths and spacings. When the paint in the self-spraying marking paint can 11 is exhausted, the locking bolt 21 is rotated to... Locking plate 22 releases support plate 8, then sliding positioning block 20 moves it away from spray line marking paint can 11. Then, the spray line marking paint can 11 can be quickly replaced by pulling it out from snap-fit ​​block 12. The spare paint cans pre-stored in storage box 16 can be replenished in time to reduce work interruption time. After the daily work is completed, the controller 14 executes an automatic calibration program to verify the measurement accuracy of laser rangefinder 18 and the transmission accuracy of lead screw 5 to ensure the line marking quality of subsequent work. This equipment, through the coordinated measurement of dual laser rangefinders 18, the precise drive of servo motor 6, and the cooperation of multiple fixed structures, is suitable for efficient and high-precision line marking operations in various scenarios such as urban roads, highways, and parking lots.
