Description

Technical Field

[0001] This invention relates to the field of road marking technology, and in particular to an intelligent road marking device. Background Technology

[0002] Road marking application refers to the process of applying marking materials such as hot-melt paint or room-temperature solvent-based paint to the road surface using specialized equipment to create traffic signs with regulatory and guiding functions. Its core is to combine road design with traffic needs, and after road surface cleaning and pretreatment, precisely apply lines, arrows, text, and other markings to ensure firm adhesion, reflectivity, and wear resistance.

[0003] Chinese patent application CN202221839202.1 discloses a road marking device, which includes a base, a material storage component, at least two spray nozzles, and a marking template. The material storage component is connected to the base. Each spray nozzle is inclined from the base toward the marking template and is fixedly connected to the base. The inlet end of each spray nozzle is connected to the material storage component. The marking template is detachably connected to the base and has at least two marking grooves that are spaced apart. Each marking groove has a different shape. The spraying end of the spray nozzle is located inside the marking template. The spray nozzle is equipped with a drive component for conveying material to be sprayed out by the spray nozzle. The spraying range of one spray nozzle covers one marking groove. This application has the effect of facilitating the marking of various road markings and improving the marking efficiency.

[0004] In the aforementioned patent, the position of the marking component is relatively fixed, and the coverage area of ​​the sprayed material is limited by the preset structure. It is difficult to dynamically adjust the stacking density and coverage uniformity of the material according to actual needs, resulting in insufficient coating thickness or excessive accumulation in some areas. At the same time, there is no real-time trimming action for the freshly applied material, and the surface is prone to sagging, unevenness, and other phenomena due to the natural flow of the material. In addition, the material relies solely on natural curing after spraying, lacking targeted accelerated cooling measures. In high ambient temperature or humidity, the slow curing speed makes it susceptible to deformation due to external forces. These problems collectively lead to a decrease in the flatness, thickness consistency, and curing stability of the markings, ultimately reducing the quality of the markings.

[0005] To address this, we propose an intelligent road marking application device. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes an intelligent road marking application device, which solves the problem that the quality of the road markings is reduced due to the decrease in the flatness, thickness consistency and curing stability of the markings in the background technology.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an intelligent road marking application device, including a pushcart, a storage box fixedly installed on the upper surface of the pushcart, a spraying component for marking lines and markings provided inside the pushcart, and a cleaning component for cleaning road impurities fixedly installed on one side of the pushcart. The spraying component includes a long rod installed inside the trolley plate. An impeller is fixedly installed on the outer surface of the long rod, and a reciprocating thread is formed on the outer surface of the long rod. A rectangular frame is movably installed on the outer surface of the long rod, and a spraying component for spraying out the marking material is movably installed inside the rectangular frame. A scraping component for evenly spreading the sprayed marking is fixedly installed on the lower surface of the rectangular frame. An air pump is fixedly installed on the upper surface of the trolley plate. The hot melt material in the storage box is sprayed onto the ground to form the marking through the spraying component. At the same time, the air pump is activated, and the air accelerates the cooling of the marking and drives the impeller. The impeller causes the long rod to rotate, and the rectangular frame moves back and forth along the reciprocating thread, which drives the spraying component to swing and pile up the material. It also drives the scraping component to spread the material evenly, improving the working effect.

[0008] Furthermore, a through groove is provided through the surface of the rectangular frame, and the spraying component is located inside the through groove. Teeth are fixedly installed on the surface of the rectangular frame, and a circular hole is provided on one side of the rectangular frame. A slide rod A is fixedly installed inside the circular hole. The slide rod A is in contact with the reciprocating thread. The impeller drives the long rod to rotate, causing the rectangular frame to move back and forth through the slide rod A and the reciprocating thread. Its teeth drive the spraying component to swing back and forth, causing the material to stack.

[0009] Furthermore, the spraying assembly includes a nozzle movably mounted inside a rectangular frame. A hose is fixedly installed at one end of the nozzle, and the hose is connected to the inside of the storage tank. Rotating shafts are fixedly installed on both sides of the nozzle, and gears are fixedly installed on the outer surface of the rotating shafts. One end of the rotating shaft is movably connected to the inside of the trolley plate. The gears mesh with each other. Through the meshing of the gears, the rectangular frame moves, driving the gears to rotate and causing the nozzle to swing back and forth. The material sprayed by the nozzle is then fed through the hose to accumulate and improve the quality of the marking.

[0010] Furthermore, the scraping assembly includes a first electric telescopic rod fixedly installed on the lower surface of the teeth.

A scraper is fixedly installed on the lower surface of the fixed plate. The height of the scraper is adjusted by the first electric telescopic rod, and the scraper is tilted and scraped by the second electric telescopic rod. The reciprocating movement of the rectangular frame drives the scraper to scrape back and forth, thereby improving the quality of the marking.

[0011] Furthermore, the cleaning component includes a motor fixedly installed on one side of the trolley board. The motor output end is equipped with a reciprocating lead screw, and a slider is sleeved on the outer surface of the reciprocating lead screw. A cleaning plate is movably installed inside the slider, and an arc edge is provided on the lower surface of the slider. When the motor is started, the reciprocating lead screw is rotated, causing the slider to move back and forth with the cleaning plate to clean the ground impurities and improve the subsequent marking effect.

[0012] Furthermore, a rod hole is provided on one side of the slider, and a slide rod B is fixedly installed inside the rod hole. The slide rod B is connected to the thread on the outer surface of the reciprocating screw. A rectangular groove is provided on one side of the slider, and a swing groove is provided inside the slider. The swing groove is connected to the rectangular groove. A crossbar is fixedly installed on the inner wall of the swing groove, and a torsion spring is fixedly sleeved on the outer surface of the crossbar. The slider moves back and forth on the reciprocating screw through the slide rod B. The crossbar can swing the cleaning plate away from the impurities when it moves to the end, and the torsion spring will reset it.

[0013] Furthermore, a brush is fixedly installed on the lower surface of the cleaning plate, and a sleeve plate is fixedly installed on the upper surface of the cleaning plate. The sleeve plate is located inside the swing groove, and a rod groove is opened through one side of the sleeve plate. The inner wall of the rod groove is fixedly connected to the outer surface of the torsion spring. Through the cooperation of the rod groove and the crossbar, the cleaning plate swings around the crossbar as the center, and the torsion spring makes the swinging cleaning plate return to its original position.

[0014] Furthermore, a lever is fixedly installed on the outer surface of the sleeve plate. The lever is located inside the rectangular groove. A sliding groove is opened on the lower surface of the trolley plate. The slider is slidably connected to the sliding groove. A rectangular plate is fixedly installed on the inner wall of the sliding groove. The rectangular plate is adapted to the rectangular groove. When the slider moves to one end of the reciprocating screw, the rectangular plate enters the rectangular groove, pushing the lever to rotate around the crossbar as the center, causing the cleaning plate to rotate clockwise, so that the brush shakes the edge impurities and improves the cleaning effect.

[0015] Furthermore, a bottom groove is formed on the surface of the trolley plate, and the spraying component is located inside the bottom groove. An air chamber is formed on the surface of the trolley plate, and one end of the air pipe is connected to the air chamber. A horizontal groove is formed inside the trolley plate, and the horizontal groove is movably connected to the rectangular frame. A short groove is formed inside the trolley plate, and the short groove is movably connected to the first electric telescopic rod. The horizontal groove, bottom groove, and short groove are connected. An infrared radiation heater is fixedly installed on the lower surface of the trolley plate. A handle is fixedly installed on the surface of the trolley plate, and a human-machine interface display screen is fixedly installed on the surface of the handle. The air pump blows air to the newly painted marking line through the air chamber, which quickly cools it and drives the spraying component to work. The bottom groove provides swing space for the spraying component.

[0016] Furthermore, the human-computer interaction display screen includes The telescopic adjustment unit controls two sets of second electric telescopic rods to adjust the tilt angle of the scraper. The ground parameter detection unit detects the ground moisture content and road surface temperature through an internally integrated humidity sensor and infrared thermometer, and then adjusts the subsequent heating power in real time. Infrared heating unit is used to heat the ground, thereby improving the adhesion between the coating and the ground. The visual navigation and positioning unit uses a camera to identify road auxiliary lines to prevent the trolley from deviating, and can also identify the preset spraying start and end points on the road, sending signals to the sprayer to start and stop. The spray control unit controls the nozzles to spray hot-melt material onto the ground for markings. The coating inspection unit uses a laser thickness gauge to detect the thickness of the markings, thereby allowing the first electric telescopic rod to adjust the height of the scraper relative to the ground.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention proposes an intelligent road marking device. The operator pushes a trolley with a handle to the work position. The motor of the cleaning component starts, driving a reciprocating screw to rotate, causing a slider to move the cleaning plate back and forth to clean impurities on the ground. When it reaches the end, a lever plate, acting on a rectangular plate, causes the cleaning plate to swing and expel impurities. An infrared radiation heater then heats the ground. A visual navigation and positioning unit uses a camera to identify auxiliary lines to prevent deviation and confirm the spraying starting point. The spraying control unit starts the nozzle, spraying material from the storage tank through a hose. Simultaneously, an air pump starts, blowing air through an air chamber to accelerate cooling of the markings and also driving an impeller to rotate a long rod. A rectangular frame moves back and forth along a reciprocating thread, and the toothed gears mesh to cause the nozzle to swing back and forth, stacking material. The rectangular frame drives the scraper of the scraping component to scrape back and forth. A first and second electric telescopic rod adjust the scraper height and tilt angle. A coating detection unit uses a laser thickness gauge to fine-tune the scraper height using the first electric telescopic rod. After the visual navigation and positioning unit identifies the endpoint, the nozzle stops working, ultimately improving the quality of the marking. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention. Example 1

[0021] To address the technical problem of how to improve the quality of rubber markings, such as... Figure 1 and Figures 7-11 As shown, the following preferred technical solution is provided: an intelligent road marking application device, including a pushcart 1, a storage box 4 is fixedly installed on the upper surface of the pushcart 1 by bolts, a spraying component 7 for marking lines is provided inside the pushcart 1, and a cleaning component 6 for cleaning road impurities is fixedly installed on one side of the pushcart 1 by bolts. The spraying component 7 includes a long rod 71 installed inside the trolley plate 1. An impeller 72 is fixedly installed on the outer surface of the long rod 71 by welding. The outer surface of the long rod 71 has reciprocating threads 73. A rectangular frame 74 is movably installed on the outer surface of the long rod 71. A spraying assembly 75 for spraying out the marking material is movably installed inside the rectangular frame 74. A scraping assembly 76 for evenly smearing the sprayed marking is fixedly installed on the lower surface of the rectangular frame 74 by bolts. An air pump 5 is fixedly installed on the upper surface of the trolley plate 1 by bolts. The spraying assembly 75 can spray the hot melt material inside the storage tank 4 onto the ground as road marking. When the spraying assembly 75 sprays, the air pump 5 starts and accelerates the cooling of the marking line through the sprayed air. At the same time, the blown air also drives the impeller 72 to rotate. The rotating impeller 72 rotates the long rod 71. At this time, the rectangular frame 74 fitted on the surface of the long rod 71 moves back and forth along the reciprocating thread 73. The spraying assembly 75 will swing back and forth due to the reciprocating movement of the rectangular frame 74, allowing the sprayed material to be stacked to improve the working effect. The reciprocating rectangular frame 74 will also scrape the stacked material evenly, further improving the working effect.

[0022] A through groove is provided on the surface of the rectangular frame 74, and the spraying component 75 is located inside the through groove. The rectangular frame 74 has teeth 741 fixedly installed on its surface by welding. A circular hole is provided on one side of the rectangular frame 74, and a slide rod A is fixedly installed inside the circular hole by welding. The slide rod A is in contact with the reciprocating thread 73. The impeller 72 drives the long rod 71 to rotate, and the rectangular frame 74 will move back and forth through the cooperation of the slide rod A and the reciprocating thread 73. At this time, the rectangular frame 74 located inside the spraying component 75 will also swing back and forth due to the reciprocating movement of the teeth 741, so that the sprayed marking material will be stacked.

[0023] The spraying assembly 75 includes a nozzle 751 movably disposed inside a rectangular frame 74. A hose 754 is bolted to one end of the nozzle 751 and connects to the inside of the storage tank 4. Rotary shafts 752 are welded to both sides of the nozzle 751. Gears 753 are welded to the outer surface of the rotating shafts 752. One end of the rotating shaft 752 is movably connected to the inside of the trolley plate 1. The gears 753 mesh with teeth 741. Through this meshing relationship, spraying occurs within the rectangular frame 74. When frame 74 starts to move, gear 753 will rotate, and nozzle 751 will tilt. When tooth 741 moves in the opposite direction, nozzle 751 will also rotate in the opposite direction. Thus, through the reciprocating movement of tooth 741, nozzle 751 can be driven to oscillate back and forth. At this time, hose 754 can also ensure that the marking material inside storage box 4 can accurately enter the nozzle 751 and then be sprayed out by the reciprocating nozzle 751, allowing the marking material to be stacked, thereby improving the quality of the marking.

[0024] The scraping assembly 76 includes a first electric telescopic rod 761 welded and fixedly installed on the lower surface of the teeth 741. A base plate 762 is bolted to the lower surface of the first electric telescopic rod 761. Two sets of second electric telescopic rods 763 are bolted to the lower surface of the base plate 762. A base 764 is welded to one end of each set of second electric telescopic rods 763. A cylinder 765 is provided inside the base 764. Fixing plates 766 are welded to both ends of the cylinder 765. A scraper 767 is bolted to the lower surface of the fixing plate 766. The height of the scraper 767 can be adjusted by the first electric telescopic rod 761, while the two sets of second electric telescopic rods 763 can make the scraper 767 perform scraping work in an inclined state. At this time, with the reciprocating rectangular frame 74, the scraper 767 can also perform the reciprocating scraping step, thereby improving the quality of the marking.

[0025] Specifically, when marking is required, the spraying component 7 inside the trolley plate 1 starts working. The spraying assembly 75 in the spraying component 7 sprays the hot melt material inside the storage tank 4 onto the ground as road markings. Then, when the spraying assembly 75 sprays, the air pump 5 on the trolley plate 1 starts, and the air pump 5 sprays air to accelerate the cooling of the markings. At the same time, the blown air drives the impeller 72 on the outer surface of the long rod 71 to rotate. Subsequently, the rotating impeller 72 drives the long rod 71 to rotate. Since the outer surface of the long rod 71 has a reciprocating thread 73, the rectangular frame 74 on its outer surface moves back and forth through the sliding rod A and the reciprocating thread 73. Then, the teeth 741 on the surface of the rectangular frame 74 move back and forth with the rectangular frame 74. Because the gears 753 on the outer surface of the rotating shafts 752 on both sides of the nozzle 751 of the spraying assembly 75 mesh with the teeth 741, the gears move back and forth when the teeth 741 move back and forth. Rotating 753 tilts the nozzle 751, causing the teeth 741 to move in the opposite direction, which in turn causes the nozzle 751 to rotate in the opposite direction, thus driving the nozzle 751 to swing back and forth. The hose 754 at one end of the nozzle 751 feeds the material in the storage box 4 into the nozzle 751, and then sprays it out by the reciprocating nozzle 751 to make the material pile up, thereby improving the quality of the marking. Then, the scraping assembly 76 on the lower surface of the rectangular frame 74 moves back and forth with the rectangular frame 74. The first electric telescopic rod 761 in the scraping assembly 76 adjusts the height of the scraper 767. The two sets of second electric telescopic rods 763 on the lower surface of the base plate 762 make the scraper 767 scrape in an inclined state. The scraper 767 on the lower surface of the fixing plate 766 at both ends of the cylinder 765 inside the base 764 at one end of the two sets of second electric telescopic rods 763 scrapes back and forth under the drive of the reciprocating movement of the rectangular frame 74, further improving the quality of the marking. Example 2

[0026] To address the technical challenges of further improving the quality of pavement marking, such as... Figures 1-7 As shown, the following preferred technical solutions are provided: The cleaning component 6 includes a motor 61 that is bolted to one side of the trolley plate 1. The output end of the motor 61 is provided with a reciprocating lead screw 62. A slider 64 is sleeved on the outer surface of the reciprocating lead screw 62. A cleaning plate 66 is movably arranged inside the slider 64. The lower surface of the slider 64 is provided with an arc edge 65. When the motor 61 is started, the reciprocating lead screw 62 can be rotated. The rotation of the reciprocating lead screw 62 can cause the slider 64 to move back and forth with the cleaning plate 66. The reciprocating cleaning plate 66 will clean the impurities on the ground, thereby improving the effect of subsequent line marking.

[0027] A rod hole 641 is provided on one side of the slider 64. A slide rod B is fixedly installed inside the rod hole 641 by welding. The slide rod B is connected to the thread on the outer surface of the reciprocating screw 62. A rectangular groove 642 is provided on one side of the slider 64. A swing groove 643 is provided inside the slider 64. The swing groove 643 is connected to the rectangular groove 642. A crossbar 644 is fixedly installed on the inner wall of the swing groove 643 by welding. A torsion spring 645 is fixedly fitted on the outer surface of the crossbar 644 by welding. The slide rod B allows the slider 64 to move back and forth on the surface of the reciprocating screw 62. The crossbar 644 allows the cleaning plate 66 to swing when it moves to one end of the reciprocating screw 62, so that the cleaned impurities are thrown out and away from the trolley plate 1. The torsion spring 645 returns the thrown cleaning plate 66 to its original position.

[0028] A brush 661 is fixedly installed on the lower surface of the cleaning plate 66 by bolts. A sleeve plate 662 is fixedly installed on the upper surface of the cleaning plate 66 by welding. The sleeve plate 662 is located inside the swing groove 643. A rod groove 663 is opened through one side of the sleeve plate 662. The inner wall of the rod groove 663 is fixedly connected to the outer surface of the torsion spring 645 by welding. Through the rod groove 663 and the crossbar 644, when the cleaning plate 66 swings, it can return to its original position with the crossbar 644 as the center and the torsion spring 645 as the center.

[0029] A lever plate 664 is fixedly installed on the outer surface of the sleeve plate 662 by welding. The lever plate 664 is located inside the rectangular groove 642. A sliding groove 11 is opened on the lower surface of the trolley plate 1. The slider 64 is slidably connected to the sliding groove 11. A rectangular plate 63 is fixedly installed on the inner wall of the sliding groove 11 by welding. The rectangular plate 63 is adapted to the rectangular groove 642. When the slider 64 moves to one end of the reciprocating screw 62, the rectangular plate 63 will enter the rectangular groove 642. At this time, the lever plate 664 located inside the rectangular groove 642 will contact the rectangular plate 63, and will be pushed by the rectangular plate 63 and rotate around the crossbar 644. At this time, the cleaning plate 66 fixed with the lever plate 664 will rotate clockwise, causing the brush 661 to make a swinging motion, which will throw away the impurities that were originally swept to both sides of the edge of the trolley plate 1, thereby improving the cleaning effect.

[0030] The surface of the trolley plate 1 has a bottom groove 12, and the spraying component 75 is located inside the bottom groove 12. The surface of the trolley plate 1 has an air chamber 13, and one end of the air pipe 51 is connected to the air chamber 13. The inside of the trolley plate 1 has a horizontal groove 14, which is movably connected to the rectangular frame 74. The inside of the trolley plate 1 has a short groove 15, which is movably connected to the first electric telescopic rod 761. The horizontal groove 14, the bottom groove 12, and the short groove 15 are connected. An infrared radiation heater 16 is fixedly installed on the lower surface of the trolley plate 1 by bolts. A handle 2 is fixedly installed on the surface of the trolley plate 1 by welding. A human-machine interaction display screen 3 is fixedly installed on the surface of the handle 2 by bolts. The air chamber 13 allows the air blown by the air pump 5 to be blown to the sprayed marking line through the air chamber 13 to quickly cool the marking line and drive the spraying component 7 to work. The bottom groove 12 allows the spraying component 75 to have enough space to swing.

[0031] Human-computer interaction display screen 3 includes The telescopic adjustment unit controls two sets of second electric telescopic rods 763 to adjust the tilt angle of the scraper 767. The ground parameter detection unit detects the ground moisture content and road surface temperature through an internally integrated humidity sensor and infrared thermometer, and then adjusts the subsequent heating power in real time. Infrared heating unit is used to heat the ground, thereby improving the adhesion between the coating and the ground. The visual navigation and positioning unit uses a camera to identify road auxiliary lines to prevent the trolley from deviating, and can also identify the preset spraying start and end points on the road, sending working and stopping signals to the spray head 751. The spray control unit controls the spray nozzle 751 to spray hot-melt material onto the ground markings; The coating inspection unit uses a laser thickness gauge to detect the thickness of the markings, thereby allowing the first electric telescopic rod 761 to adjust the height of the scraper 767 relative to the ground.

[0032] Specifically, before spraying the marking material, motor 61 starts, driving reciprocating screw 62 to rotate. Slider 64, carrying cleaning plate 66, moves back and forth along slide groove 11. Brush 661 cleans impurities on the ground. Then, when slider 64 moves to one end of reciprocating screw 62, rectangular plate 63 enters rectangular groove 642, pressing against push plate 664 to rotate around crossbar 644, causing cleaning plate 66 to rotate clockwise, allowing brush 661 to swing and remove edge impurities. Subsequently, torsion spring 645 resets cleaning plate 66, continuing cleaning to improve subsequent marking effects. After cleaning, infrared radiation heater 16 is activated to heat the ground, improving coating adhesion. Simultaneously, the ground parameters on human-machine interface display screen 3 are displayed. The detection unit detects the ground moisture content and temperature, adjusts the power of the infrared heating unit, and then the visual navigation and positioning unit identifies the auxiliary line to prevent deviation through the camera, identifies the starting and ending points of the spraying, and prepares the nozzle 751 for work and stop signals. Subsequently, the air pump 5 starts, and the airflow blows through the air chamber 13 to the sprayed marking line to accelerate cooling, while driving the spraying component 7 to work. The bottom groove 12, the horizontal groove 14, and the short groove 15 ensure smooth movement of the component. During spraying, the spraying control unit controls the nozzle 751 to spray the material, the coating detection unit detects the marking line thickness, and the first electric telescopic rod 761 adjusts the height of the scraper 767. The telescopic adjustment unit controls the second electric telescopic rod 763 to adjust the tilt angle of the scraper to improve the marking quality.
