Description

Technical Field

[0001] The invention relates to the technical field of road marking cleaning, in particular to a road marking cleaning device. Background Art

[0002] Road markings refer to the markings on the road surface that use lines, arrows, text, facade markings, raised road signs and contour marks to convey traffic information such as guidance, restriction and warning to traffic participants. They have the function of controlling and guiding traffic and can be used in conjunction with signs or alone. When the road markings are covered with dust, dirt, debris, etc., their instructive and warning functions will be greatly reduced. Therefore, it is necessary to clean the road markings regularly using cleaning devices.

[0003] Most of the current road marking cleaning devices clean road markings through automatic cleaning brush rollers. Due to the wide variety of garbage on the road, some long garbage, hair, flocs and other garbage are easily entangled on the cleaning brush roller, causing some bristles on the brush roller to be unable to unfold normally, thereby affecting the subsequent cleaning effect of the brush roller. Continuous entanglement may even cause damage to the bristles and reduce the service life of the brush roller.

[0004] On the other hand, a road marking cleaning device disclosed in the Chinese invention patent application disclosure specification CN112681194B pulls the pressure rod downward to drive the sponge pad downward to contact the marking line, and at the same time drives the wedge block downward, pushes the connecting block to move to the left, aligns with the opening of the support tube, and sprays water onto the marking line through the nozzle, so as to easily clean the road marking line. However, the above scheme cannot effectively clean the stubborn adhesions on the road marking line. There are many kinds of garbage on the road. Some sticky substances will adhere tightly to the road marking line after being crushed by vehicles, such as chewing gum, jelly, asphalt spilled when repairing the road, etc. These stubborn adhesions are difficult to be cleaned by a cleaning brush. Therefore, we propose a road marking cleaning device to solve the above problems. Summary of the invention

[0037] Please refer to Figure 4 , Figure 5 and Figure 6 Two symmetrical limit adjustment components 3 are arranged on the outside of the U-shaped carrier 22. The limit adjustment components 3 include a U-shaped pushing block 31, a cylindrical rotating frame 32 fixed to the end of the square combined rotating rod 26, and a limit plate 33 fixed to the outer surface of the U-shaped carrier 22. Two symmetrical circular sliders 34 are fixed to the inner wall of the U-shaped pushing block 31, and the two circular sliders 34 are slidably connected to the inner wall of the cylindrical rotating frame 32.

At the same time, under the driving action of the first pulley 48, the second pulley 49 and the belt, the strip rotating frame 43 rotates, and the garbage entangled on the cleaning brush roller 42 is picked out by the debris removal rod 45. Under the sliding action of the teardrop-shaped guide rail frame 46 and the guide column 47, the push plate 44 pushes the entangled objects picked out by the debris removal rod 45 toward the first dust hopper 411, and finally sucks them into the dust collector 410; When encountering stubborn adhesions on the road markings, the auxiliary lifting guide frame 21 is moved to the top of the stubborn adhesions, and hot air is blown into the U-shaped carrier frame 22 by the hot air blower 213 to soften the stubborn adhesions. The motor on the auxiliary lifting guide frame 21 is driven to rotate the reciprocating screw 23, and the internal thread moving block 24 and the U-shaped carrier frame 22 are moved. Under the sliding action of the L-shaped sliding rod 214 and the auxiliary lifting guide frame 21, when the U-shaped carrier frame 22 moves to both sides of the auxiliary lifting guide frame 21, the U-shaped carrier frame 22 is lifted, so that the U-shaped carrier frame 22 is lowered when it is in the middle position, and the cutting scraper 27 is fitted with the surface of the road markings. The movement of the internal thread moving block 24 drives the gear 211, the hollow tube 210 and the Z-shaped rotating rod 28 to rotate, and the cutting scraper 27 is reciprocated by the lower arc sliding block 29, so that the cutting scraper 27 is saw-shaped to scrape off the stubborn adhesions on the road markings. When the U-shaped carrier 22 and the cutting scraper 27 move to the side of the auxiliary lifting guide frame 21 where the third wedge block 38 is fixed, the U-shaped push block 31 moves toward the U-shaped carrier 22 under the action of the first wedge block 36 and the third wedge block 38, the first wedge strip 310 and the third wedge strip 312, and the circular slider 34 pushes the columnar rotating frame 32 and the cutting scraper 27 to rotate. When the U-shaped carrier 22 and the cutting scraper 27 move to the side of the auxiliary lifting guide frame 21 where the fourth wedge block 39 is fixed, the second wedge block 37 and the fourth wedge block 39, the second wedge strip 311 and the fourth wedge strip 313 Under the toggling action, the U-shaped pushing block 31 moves away from the U-shaped carrier frame 22, and the circular slider 34 pushes the cylindrical rotating frame 32 and the cutting scraper 27 to reverse, so that the cutting scraper 27 always forms a certain angle with the road marking to scrape off stubborn adhesions. The device can effectively scrape off stubborn adhesions on the road markings through the scraping method of the reciprocating sawing of the cutting scraper 27 and the scraping method of the cutting scraper 27 always forming a certain angle with the road markings, and can quickly remove long strips of garbage and hair and other entanglements wrapped around the cleaning brush roller 42, thereby ensuring the cleaning efficiency and service life of the cleaning brush roller 42.
