Description

Technical Field

[0001] The utility model relates to the technical field of marking devices, in particular to a quick temporary marking device. Background Art

[0002] Traditional temporary road marking devices have long relied on manual operation to complete road marking tasks. In this mode, workers need to hold the paint spray nozzle and precisely control the movement of their arms to accurately point the spray head at the ground, spraying paint to form the desired line.

[0003] Workers need to continuously and steadily hold and move the heavy paint spray hose, which not only requires high physical strength but also easily leads to fatigue after long hours of work, which can affect the accuracy and efficiency of marking. In addition, to maintain the cleanliness of the road surface and the clarity of the markings, multiple re-spraying operations are often required, further increasing labor and time costs.

[0031] The following combination Figures 1 to 2 , describing a quick temporary marking device according to an embodiment of the present utility model.

[0032] A rapid temporary marking device includes a frame 1, a movable plate 11, a mounting assembly 3, a marking assembly 4 and a driving assembly 5;

[0033] The movable plate 11 is slidably connected to the left and right sides of the bottom of the frame 1. The marking assembly 4 includes a first spray head 41, which is vertically mounted on the bottom of the movable plate 11. The first spray head 41 corresponds to the movable plate 11 one by one and is used to spray paint onto the road surface.

[0034] The frame 1 is provided with a driving assembly 5, the movable ends of which are respectively connected to the two movable plates 11. The driving assembly 5 is used to drive the two movable plates 11 to move toward or away from each other. The movable direction of the movable plates 11 is left and right.

[0035] A mounting assembly 3 is provided on the top of the frame 1 . The mounting assembly 3 includes a U-shaped clamp 31 . The U-shaped clamp 31 is used to mount the frame 1 on an external mobile work platform.

[0036] The installation assembly 3 in the scheme is arranged at the top of the frame body 1, and the U-shaped clamping piece 31 in the installation assembly 3 can install the quick temporary marking device of the scheme on various mobile operation platforms, thereby enhancing the working range and flexibility of the marking device.

[0037] The bottom of the frame body 1 is slidably connected with two movable plates 11, and the first spray heads 41 are installed on the movable plates 11. The width of the marking line can be adjusted by adjusting the distance between the two movable plates 11 through the driving assembly 5. In actual marking operation, when a narrow line needs to be marked, the driving assembly 5 drives the two movable plates 11 to move close to each other, so that the distance between the first spray heads 41 is reduced, thereby spraying a narrow line. When a wide line needs to be marked, the driving assembly 5 drives the movable plates 11 to move away from each other, so that the distance between the first spray heads 41 is increased, thereby flexibly meeting the needs of marking lines of different widths.

[0038] Therefore, when the mobile operation platform moves on the road, the first spray heads 41 can spray paint on the road surface at the same time to quickly perform the marking operation, which not only can reduce the labor intensity of the operator and improve the marking efficiency, but also can improve the safety of the operator. At this time, the operator can stand in the safe operation area of the mobile operation platform, and does not need to manually mark the line, thereby avoiding the potential collision risk and complex road conditions, greatly ensuring the personal safety of the operator during operation, reducing the operation risk coefficient to the minimum, and solving the problems of high labor intensity and high risk coefficient of traditional manual marking.

[0039] The marking assembly 4 further comprises a second spray head 42, which is located at the bottom of the frame body 1 and between the two first spray heads 41.

[0040] Simultaneous starting of the first spray heads 41 and the second spray head 42 can draw three parallel road indication lines. The operator can adjust the spraying frequency, spraying time, spraying amount and other parameters of the first spray heads 41 and the second spray head 42, so as to draw different road indication lines, thereby further reducing the marking intensity and difficulty of the operator.

[0041] The marking assembly 4 comprises a paint storage tank 43, a pressure supply machine 44, a paint spraying pipe 45, mechanical valves and a controller. The paint storage tank 43 and the pressure supply machine 44 are both installed in the frame body 1. The output end of the paint storage tank 43 is in communication with the input end of the pressure supply machine 44. The output end of the pressure supply machine 44 and the input end of the paint spraying pipe 45 are in communication. The multiple output ends of the paint spraying pipe 45 are all provided with the mechanical valves. The multiple output ends of the paint spraying pipe 45 are respectively in communication with the second spray head 42 and the two first spray heads 41. The mechanical valves are electrically connected with the controller.

[0042] The paint storage tank 43 and the pressure supply machine 44 are integrated and installed in the frame 1, forming a compact and efficient paint supply system. The pressure supply machine 44 pressurizes the paint in the storage tank and delivers it to the paint spray pipe 45, avoiding the problems of unstable flow and intermittent flow interruption caused by the natural gravity flow of the paint in traditional manually held paint pipes. In long-distance road marking projects, as the mobile work platform continues to move forward, the pressure supply machine 44 continuously and stably outputs pressure to ensure that the paint flows continuously and at a constant pressure to each spray head. Whether on a flat road section or a slightly undulating area, it can ensure that the paint is sprayed evenly, making the entire marking line continuous and without breakpoints, improving the efficiency and quality of the marking, and reducing repeated work caused by poor paint supply.

[0043] The marking assembly 4 also includes a mechanical valve and a controller. The controller precisely adjusts the opening and closing of the mechanical valve according to a preset program to create different types of lines. When drawing dashed lines, the controller sends instructions to adjust the opening and closing frequency of the mechanical valve, ensuring that the amount of paint sprayed each time remains within a certain range, thus forming evenly spaced dashed lines. When drawing thick solid lines, the mechanical valve is opened wider, allowing the paint to flow out in large quantities and quickly, widening the line width. This ensures that the entire lane dividing line is clearly defined and meets standard specifications, greatly improving the accuracy and professionalism of the marking.

[0044] At this time, the operator can remotely and centrally control the mechanical valve through the controller, without having to manually turn the valve to adjust the paint flow as in the traditional way. This not only avoids the health risks of operators frequently approaching the paint spraying area and getting contaminated by paint and inhaling volatile gases, but also makes the operation more convenient and efficient.

[0045] The driving assembly 5 includes a motor 51, a driving worm gear 52 and a passive worm 53. The motor 51 is horizontally mounted on the inner wall of the frame 1. The output shaft of the motor 51 is fixedly sleeved with the driving worm gear 52. The driving worm gear 52 and the passive worm 53 are engaged with each other. The passive worm 53 is rotatably mounted on the inner wall of the frame 1. The length direction of the passive worm 53 is the left-right direction. The top of the movable plate 11 is movably connected to the passive worm 53.

[0046] The passive worm 53 is a bidirectional worm;

[0047] The motor 51 is electrically connected to the controller.

[0048] The motor 51 is started, and the motor 51 drives the active worm gear 52 to rotate. Since the active worm gear 52 is meshed with the passive worm 53, the passive worm 53 is driven to rotate. Since the passive worm 53 is a bidirectional worm, the two movable plates 11 connected to the passive worm 53 move closer to or farther from each other in the left and right directions.

[0049] In addition, the motor 51 is electrically connected to the controller, and the operator can control the speed and rotation direction of the motor 51 through the controller to adjust the movement direction and movement distance of the two movable plates 11, thereby completing the marking work more efficiently.

[0050] Movable through holes 12 are provided on both the left and right sides of the bottom of the frame 1. The length direction of the movable through hole 12 is the left and right direction. The movable through hole 12 is connected to the inner cavity of the frame 1. The bottom of the movable plate 11 passes through the bottom of the frame 1 through the movable through hole 12, and the movable plate 11 is slidably connected to the movable through hole 12.

[0051] Through the movable through hole 12 opened at the bottom of the frame 1, the bottom of the movable plate 11 passes through the movable through hole 12 and slides in the left and right directions, effectively avoiding the movable plate 11 from colliding with the frame 1 when moving in the left and right directions, extending the service life of the movable plate 11 and the frame 1, and reducing the cost of repair or replacement due to component damage.

[0052] At the same time, the movable through hole 12 can limit the movable direction of the movable plate 11, thereby reducing the deviation and shaking of the movable plate 11, which may cause the scribed line to bend.

[0053] A movable wheel 13 is provided at the bottom of the movable plate 11 .

[0054] The movable wheels 13 can provide better support for the movable board 11 , thereby reducing the risk of the movable board 11 tilting, shaking or even falling due to unstable support.

[0055] There are at least two mounting components 3, and multiple mounting components 3 are installed side by side on the top of the frame 1;

[0056] The mounting assembly 3 further includes a lifting cylinder 32 and a clamping screw 33. The mounting end of the lifting cylinder 32 is fixedly connected to the inner wall of the frame 1, and the movable end of the lifting cylinder 32 passes through the top of the frame 1 and is fixedly connected to the U-shaped clamping member 31.

[0057] The top of the U-shaped clamping member 31 is threadedly connected to a clamping screw 33 , and the bottom of the clamping screw 33 passes through the U-shaped clamping member 31 and abuts against the mobile working platform.

[0058] At least two mounting assemblies 3 are provided on the frame 1 to enhance the stability of the entire device on a mobile work platform or other clamped object. During the marking process, especially when the device is moving, the multiple mounting assemblies 3 work together to effectively prevent the device from shifting, loosening, or falling.

[0059] The U-shaped clamping piece 31 is clamped on the mobile work platform, and the clamping screw 33 is rotated, so that the end of the clamping screw 33 extends into the U-shaped clamping piece 31 and presses downward on the mobile work platform, thereby stably installing the quick temporary marking device of the present application on the bottom of the mobile work platform.

[0060] Then the lifting cylinder 32 is started, the piston rod of the lifting cylinder 32 extends outward, so that the frame body 1 moves downward until the movable wheel 13 contacts the ground, thereby accurately adjusting the distance between the first spray head 41, the second spray head 42 and the ground, ensuring that the spray head is within the ideal spray distance range during each marking, so that the sprayed paint uniformly falls on the ground, forming a line with consistent width and clear and beautiful appearance.

[0061] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for the purpose of explaining the principles of the present application, and cannot be interpreted in any way as a limitation on the scope of protection of the present application. Based on the explanations herein, those skilled in the art can conceive other specific embodiments of the present application without creative labor, and these embodiments will fall within the scope of protection of the present application.
