Description

Technical Field

[0001] The invention relates to the technical field of road marking construction, and in particular to an integrated intelligent scraping device for road marking construction. Background Art

[0002] Road marking equipment is a road construction machine widely used in roads, highways, parking lots, squares and runways to mark different restrictions, guidance and warning signs on the flat ground. With its advantages of fast, efficient and accurate, the marking equipment has played a huge role in urban planning and highway construction, saving the construction period and economic investment of road construction to the greatest extent. However, due to the long-term use of the road surface, it is difficult to ensure that the road surface is flat and not rugged, especially the influence of various debris such as gravel. The marking equipment will inevitably produce bumps during the walking process, resulting in factors such as vibration and displacement of the marking bucket, resulting in the loss of some markings, affecting the integrity and aesthetics of the marking. For such defects, when people use scraping and coating to mark the lines, the marking bucket has a certain downward elasticity to minimize the breakage caused by the bumps of the equipment, but it still cannot completely avoid the defects. It is also necessary to rely on manual adjustment of the frame and move it to the appropriate position for scraping and coating. However, it is difficult to control the perfect corresponding position in this way. Moreover, if it is only a narrow defect, the scraping width must be readjusted, and it can only be supplemented by spraying during manual inspection. Therefore, it is urgent to design an integrated intelligent scraping device for road marking construction to improve construction efficiency. Summary of the invention

[0028] See also Figures 1 to 3 The present invention provides an integrated intelligent scraping device for road marking construction, and the technical solution is as follows:

The paint tank 2, the scraping mechanism 3, the detection mechanism 4, the paint touch-up mechanism 5 and the control mechanism are all arranged on a mobile trolley 1, and the scraping device is driven to move by the mobile trolley 1, which is convenient for construction. The paint tank 2 is fixedly arranged at the front end of the mobile trolley 1, and a feed port 6 is fixedly arranged on the top of the paint tank 2, and the paint raw material is poured in through the feed port 6. The scraping mechanism 3 is connected to the paint tank 2, and the scraping mechanism 3 includes a spraying assembly 31 and a scraping assembly 32.

According to the amount of paint discharged, the roller 324 is driven to move by the electric telescopic rod 322, and the contact force between the roller 324 and the road surface is controlled, thereby controlling the thickness of the marking line scraped by the roller 324.

[0030] A detection mechanism 4 is arranged behind the scraping mechanism 3. The detection mechanism 4 includes a mounting seat 41 and a camera 42. One end of the mounting seat 41 is fixedly connected to the mobile car 1, and the other end of the mounting seat 41 is connected to the camera 42. The camera 42 is used to shoot the markings on the road surface and transmit the image information of the markings to the control mechanism. The control mechanism includes a control chip and a drive chip, and the control chip is electrically connected to the drive chip. The camera 42 performs visual detection. The visual detection of road markings mainly relies on the camera 42 to obtain the road image, and then transmits the collected image information to the control chip. The image is analyzed by the image processing algorithm of the control chip to identify the shape, color, integrity and other characteristics of the road markings. By comparing with the preset standard or template, the system can determine whether there are defects in the road markings and mark the location where the road markings have defects. It should be noted that the visual detection technology is relatively mature, and this application directly uses visual detection technology to detect defects in road markings.

[0031] After obtaining the position of the road surface defect, the road marking defect position is repainted by controlling the paint repainting mechanism 5. Specifically, the paint repainting mechanism 5 includes a paint repainting component 51 and a moving component 52 that drives the paint repainting component 51 to move. The moving component 52 includes a moving motor 521, a screw rod 522, a moving block 523 and an encoder 524. The moving motor 521, the screw rod 522 and the moving block 523 are all arranged on a fixed seat, and the fixed seat is fixedly mounted on the moving trolley 1.

An encoder 524 is connected to the moving motor 521, and the encoder 524 is electrically connected to the control chip. A paint touch-up assembly 51 is provided on the moving block 523, and the paint touch-up assembly 51 includes a paint touch-up tube 511, a second valve and a second nozzle. The paint touch-up tube 511 is connected to the paint tank 2 through a hose 512, and the paint touch-up tube 511 is connected to the second nozzle through the second valve. The paint touch-up tube 511 is fixedly arranged on the moving block 523, and the moving block 523 drives the paint touch-up tube 511 to move.

[0032] The camera 42 captures the road markings drawn by the scraping mechanism 3 to obtain the image information of the road markings, and transmits the image information to the control chip, which analyzes whether the road markings have defects. If there are defects in the road markings, the road defect position information is marked, and the moving motor 521 is controlled to drive the screw rod 522 to rotate, thereby driving the moving block 523 to move. The encoder 524 is electrically connected to the control chip, and the encoder 524 transmits the movement information of the moving block 523 to the control chip. The control chip obtains the current position of the moving block 523 according to the movement information of the moving block 523, and controls the moving motor 521 again to accurately move the moving block 523 to the road defect position, that is, to move the paint repair tube 511 to the road marking defect position, and sprays the paint on the marking defect position by controlling the second valve, and the marking is repaired to make the marking complete.

[0033] Furthermore, the paint tank 2 further includes a spreading mechanism 7, which includes a glass bead storage box 71, a spreading pipe 72 and a third valve 73. The glass bead storage box 71 is arranged behind the paint tank 2, and the spreading pipe 72 is arranged behind the paint touch-up pipe 511. One end of the spreading pipe 72 is connected to the glass bead storage box 71, and the other end is connected to the third valve 73. By placing glass beads of different diameters in the glass bead storage box 71, the third valve 73 is controlled to make the glass beads fall on the marked line. The types of glass beads mentioned are 40 mesh (0.3-0.6 mm), 60 mesh (0.3-0.425 mm), 80 mesh (0.2-0.3 mm), 100 mesh (0.15-0.25 mm), 120 mesh (0.12-0.18 mm) and 150 mesh (0.12-0.15 mm).

[0034] Furthermore, a heating mechanism 8 is also included, and the heating mechanism 8 includes an inner tank 81, a heating wire 82 and a temperature sensor 83. The inner tank 81 is fixedly arranged in the paint tank 2, and a heating wire 82 is fixedly arranged in the gap between the inner tank 81 and the paint tank 2. The gap between the inner tank 81 and the paint tank 2 is filled with a heating liquid, and a temperature sensor 83 is fixedly arranged on the inner wall of the inner tank 81. The temperature sensor 83 is connected to the control chip. The temperature of the heating liquid is increased by the heating wire 82, so that the paint inside the inner tank 81 is heated to a suitable temperature, and the temperature of the raw material is detected by the temperature sensor 83. A stirring motor 9 is fixedly arranged on the top of the paint tank 2, and the output end of the stirring motor 9 extends through the top of the paint tank 2 to the inside of the paint tank 2. One end of the output end of the motor is placed in the paint tank 2 and is fixedly connected to a stirring shaft 10, and a plurality of blades 11 are fixedly arranged on the outer wall of the stirring shaft 10. By turning on the stirring motor 9, the stirring motor 9 drives the stirring shaft 10 to rotate, thereby driving the blades 11 to rotate so that the spray paint raw materials are mixed more fully, thereby enhancing the scraping effect of the road marking construction.

[0035] Furthermore, it also includes a drying mechanism 12, which includes a housing 121, a heating pipe 122 and a fan 123. The housing 121 is fixed on the mobile vehicle 1 and is located behind the paint touch-up pipe 511. The heating pipe 122 and the fan 123 are both arranged in the housing 121, and the heating pipe 122 is located below the fan 123, and a plurality of heating pipes 122 are arranged. According to the temperature and humidity conditions, the air is heated by the heating pipe 122 when necessary, and then the airflow blown out by the fan 123 drives the hot air to blow toward the marking line, so as to facilitate the drying of the marking line paint.

[0036] Working principle: When the device is needed for road marking construction, the staff drives the mobile trolley 1 to carry out road marking construction, adds the paint raw materials into the paint tank 2 from the feed port 6, turns on the stirring motor 9, and the stirring motor 9 drives the stirring shaft 10 to rotate, thereby driving the blade 11 to rotate to make the paint raw materials mixed more fully. Reduce pollution during road marking construction. The heating liquid temperature is increased by the heating wire 82, thereby heating the paint inside the inner tank 81 to a suitable temperature. The temperature sensor 83 detects the raw material temperature and transmits the temperature data to the control chip. The first valve 312 is controlled, and the mixed paint is sprayed on the road surface by the first nozzle 313 after passing through the discharge pipe 311. The paint output amount is obtained according to the opening of the first valve 312, and the electric telescopic rod 322 is controlled according to the output amount and the required marking thickness. The electric telescopic rod 322 drives the roller 324 to move. After the roller 324 moves to a suitable position, the paint sprayed on the road surface is scraped.

[0037] After scraping, the painted line is photographed by camera 42 to obtain line image information, which is transmitted to the control chip. The control chip is used to identify and process the line image information to obtain the position of the line defect, and the moving motor 521 is controlled to drive the screw rod 522 to rotate, thereby driving the moving block 523 to move, and the moving block 523 drives the paint touch-up tube 511 to move. At the same time, the encoder 524 records the motor rotation data, thereby obtaining the movement displacement data of the moving block 523. The encoder 524 feeds back the movement displacement data of the moving block 523 to the control chip. The control chip obtains the current position information of the moving block 523, and continues to control the moving motor 521 until the paint touch-up tube 511 is located above the defective position of the road marking, and then controls the second valve to export the paint through the paint touch-up tube 511 and the second nozzle, and accurately touches up the defective position of the road marking to make the marking complete.

[0038] Then, glass beads of different diameters are placed in the glass bead storage box 71, and the glass beads fall into the spreading tube 72. The glass beads are guided out and spread on the paint on the road marking by controlling the third valve 73, and the spreading construction of the glass beads is completed. Finally, according to the temperature and humidity conditions, the surrounding air is heated by the heating tube 122 when necessary, and the heated air is blown to the road marking by the fan 123, so as to facilitate the drying of the road marking paint.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
