Description
Technical Field
[0001] This utility model relates to the field of road construction technology, specifically to a road marking cleaning device for highway engineering. Background Technology
[0002] Road traffic markings refer to signs on carriageways, curbs, and obstacles that use prescribed lines, patterns, or words to indicate the guidance, restrictions, and warnings required by traffic rules.
[0003] Patent CN221052332U discloses a road marking removal vehicle for highway engineering. This patent, through the combined use of an opening, a fixing rod, a spring, a soundproof cover, and a sound-absorbing panel, isolates the noise generated during the removal of road markings by covering the grinding disc with a grinding cover. The noise is then absorbed by the sound-absorbing panel, preventing excessive noise from affecting the health of workers who work long hours and also avoiding disturbing nearby residents. However, this patent still has the following problems in practical use:
[0004] By covering the grinding hood with the grinding disc, the noise generated when the grinding disc grinds and removes road markings is isolated inside the soundproof cover, and the noise is absorbed by the sound-absorbing panel, thus avoiding excessive noise during grinding. However, in actual use, when the grinding disc rotates to remove road markings, it is subjected to intense friction through its own friction, and the surface heat will continue to rise. If the grinding disc continues to grind, it is easy to overheat, which will affect the service life of the grinding disc. In addition, the use of an air pump to suck up dust during the marking removal process will increase the overall use and manufacturing costs.
[0005] A road marking cleaning device for highway engineering is proposed to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a road marking cleaning device for highway engineering, in order to solve the problems mentioned in the background art. Currently, by covering the grinding cover and grinding disc, the noise generated when the grinding disc grinds and removes the road markings is isolated inside the soundproof cover and absorbed by the sound-absorbing plate, thus avoiding excessive noise during grinding. However, in actual use, when the grinding disc rotates to remove the road markings, it is subject to intense friction, and the surface heat will continue to rise. If the grinding disc continues to grind, it is easy to overheat, affecting the service life of the grinding disc. In addition, the use of an air pump to suck up dust during the marking removal process increases the overall use and manufacturing costs.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This road marking cleaning device has cleaning components installed on the top and bottom of the vehicle body, which allows for spraying and cooling of the grinding disc during the cleaning of road markings, preventing overheating and dust generation. Furthermore, the spraying is achieved through the rotation of the grinding disc, reducing manufacturing and operating costs. The specific details are as follows:
[0020] 1. Cleaning components are installed at the top and bottom of the vehicle body. When cleaning road markings, the vehicle body is moved, and the handwheel is turned to rotate the threaded rod on the mounting frame, which lowers the movable frame. This brings the rotating wheel on the movable cover into contact with the ground. Continuing to turn the handwheel brings the grinding disc into contact with the ground, causing the fixed block on the movable cover to slide on the movable rod and stretch the telescopic spring. The drive motor on the mounting plate is activated, driving the rotating shaft to rotate, causing the grinding disc to rotate and clean the markings. The movable cover prevents dust and has a certain noise reduction effect. The rotation of the rotating shaft also drives the offset disc to rotate. After the offset disc rotates, the spherical part slides inside the annular groove. Due to the offset rotation of the offset disc, the sliding connection between the annular groove and the spherical part drives the two sliding rods on the movable frame to move... The left sliding rod moves back and forth, causing the left piston to slide inside the left cylinder. When the left piston moves to the right in the left cylinder, the first one-way valve inside the water pumping pipe opens and the second one-way valve inside the water delivery pipe closes. The piston can pump water from the water tank into the left cylinder. When the left piston moves to the left, the first one-way valve inside the water pumping pipe closes and the second one-way valve inside the water delivery pipe opens. The movement of the piston can push water from the left cylinder into the water delivery pipe, which is then sprayed out through the nozzle to spray the grinding disc and cool it down. The cleaning component allows the grinding disc to be sprayed and cooled down when cleaning road markings, preventing the grinding disc from overheating and avoiding dust generation. The spraying is achieved by the rotation of the grinding disc, reducing manufacturing and operating costs.
[0021] 2. During the rotation of the rotating shaft, the right sliding rod moves back and forth, causing the right piston to move back and forth inside the right cylinder. When the right piston moves to the left in the right cylinder, the second one-way valve inside the suction pipe opens and the second one-way valve inside the air inlet pipe closes. This allows the movement of the right piston to draw air from the suction pipe, allowing dust particles generated during cleaning to enter the right cylinder under suction. When the right piston moves to the right, the second one-way valve inside the suction pipe closes and the second one-way valve inside the air inlet pipe opens. The piston pushes the dust inside the right cylinder into the air inlet pipe. The dust can then enter the breathable dust collection bag through the dust collection hood. The breathable dust collection bag is connected to the dust collection hood by a threaded connection via an installation ring, making it easy to install and remove. This facilitates cleaning of the inside of the breathable dust collection bag. Furthermore, during the cleaning process, the rotation of the grinding disc can be used to adsorb dust, improving practicality. Attached Figure Description

[0032] Working principle: Before using this type of road marking cleaning device, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 5 As shown, cleaning components 2 are installed at the top and bottom of the vehicle body 1. When cleaning road markings, the vehicle body 1 is moved, and the handwheel 204 is turned to drive the threaded rod 203 to rotate on the mounting bracket 202, which in turn drives the movable bracket 206 to descend, so that the rotating wheel 213 on the movable cover 212 contacts the ground. Continuing to turn the handwheel 204, the grinding disc 211 contacts the ground, causing the fixed block 214 on the movable cover 212 to slide on the movable rod 215 and stretch the telescopic spring 216, thus activating the cleaning mechanism. The drive motor 209 on the mounting plate 208 drives the rotating shaft 210 to rotate, causing the grinding disc 211 to rotate and grind and clean the marking lines. The movable cover 212 prevents dust from being emitted and also has a certain noise reduction effect. While the rotating shaft 210 is rotating, it can also drive the offset disc 217 to rotate. After the offset disc 217 rotates, the spherical part 219 slides inside the annular groove 218. Due to the offset rotation of the offset disc 217, the sliding connection between the annular groove 218 and the spherical part 219 can drive the two sliding rods 2. 20 moves back and forth on the movable frame 206. During the reciprocating movement, the left sliding rod 220 drives the left piston 222 to slide inside the left cylinder 221. When the left piston 222 moves to the right in the left cylinder 221, the first one-way valve inside the water pumping pipe 224 opens and the second one-way valve inside the water delivery pipe 225 closes. Water can be pumped from the water tank 223 into the left cylinder 221 through the piston 222. When the left piston 222 moves to the left, the first one-way valve inside the water pumping pipe 224 closes and the second one-way valve inside the water delivery pipe 225 closes. 5. When the internal second check valve opens, the movement of piston 222 can push the water inside the left cylinder 221 into the water supply pipe 225, and spray it out through the nozzle to spray the grinding disc 211 and cool it down. The cleaning component 2 enables the grinding disc 211 to be sprayed and cooled down when cleaning road markings, so as to avoid overheating of the grinding disc 211 and avoid generating dust. The spraying is achieved by the rotation of the grinding disc 211, which reduces manufacturing and usage costs.
[0033] During the rotation of the rotating shaft 210, the right sliding rod 220 reciprocates, causing the right piston 222 to reciprocate inside the right cylinder 221. As the right piston 222 moves to the left within the right cylinder 221, the second one-way valve inside the suction pipe 228 opens, and the second one-way valve inside the air inlet pipe 227 closes. This allows the movement of the right piston 222 to draw air from the suction pipe 228, enabling dust particles generated during cleaning to enter the right cylinder 221 under suction. When the right piston 222 moves to the right, the suction pipe 228... The internal second one-way valve is closed, and the internal second one-way valve of the air inlet pipe 227 is opened. The piston 222 can push the dust inside the right cylinder 221 into the air inlet pipe 227. The dust can enter the breathable dust collection bag 230 through the dust collection hood 226. The breathable dust collection bag 230 is threadedly connected to the dust collection hood 226 through the mounting ring 229, which makes it easy to disassemble and install the breathable dust collection bag 230 and facilitates the cleaning of the inside of the breathable dust collection bag 230. In addition, the dust can be adsorbed by the rotation of the grinding disc 211 during the cleaning process, which improves the practicality.
