Description

Technical Field

[0001] This utility model relates to the field of road marking removal technology, and in particular to a road marking removal vehicle for highway engineering. Background Technology

[0002] Road markings are traffic safety facilities consisting of various lines, arrows, text, vertical markings, raised pavement markers, and delineators painted on the road surface. Road markings effectively guide drivers' vision, regulate vehicle routes, greatly improve road safety, and reduce accident rates. When roads are widened, merged, or other redesigned road space, new traffic markings must be installed, requiring the removal of old markings. Road marking removal equipment is specialized equipment used to remove residual old lines before the construction of road markings on highways, urban roads, and other similar roads.

[0003] According to the search, the patent (application number: 202123048140.0) discloses "a road marking removal vehicle for highway engineering". The device uses a scraper to scrape off the road markings over a large area, and then uses a brush to clean the road markings after the first scraping, so that the road markings are cleaned more thoroughly.

[0004] However, the device makes it difficult to observe the cleaning status of the markings during operation, and it easily generates dust during the scraping process, which not only affects the working line of sight but also poses a risk to human respiration. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a road marking removal vehicle for highway engineering, which overcomes the shortcomings of the prior art and effectively solves the problems that it is not easy to observe the cleaning status of the road markings, and that dust is easily generated during the scraping process, which not only affects the working vision, but also easily causes harm to the human body's breathing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A road marking removal vehicle for highway engineering includes a vehicle body, with a removal mechanism connected to the bottom of the vehicle body. The removal mechanism includes a fixed plate, a handle screw rotatably connected to the top of the fixed plate, a guide rod disposed on one side of the handle screw, a fan disposed on the other side of the handle screw, a flexible hose inserted into one end of the fan's air outlet, a fixed box inserted into one end of the flexible hose, a collection box inserted into the fixed box, a T-pipe inserted into one end of the fan's air inlet, connecting pipes respectively inserted into both ends of the T-pipe, a dust suction cover inserted and fixed to the bottom of the connecting pipe, a rotating rod rotatably connected to the bottom of the fixed plate, a mounting plate fixed to the bottom of the rotating rod, and a grinding disc mounted on the bottom of the mounting plate.

[0008] By moving the vehicle body, when the road marking is being cleared, the handle screw is turned, and the guide rod slides along the through hole to adjust the height of the clearing mechanism, bringing the grinding disc below closer to the road marking. A servo motor drives the rotating rod to rotate through meshing gears, and the rotating mounting plate drives the grinding disc to rotate and clear the road marking. During the clearing process, the mounting plate drives the brush bristles to rotate, expelling stones from the road surface in advance. Then, a blower sucks up the dust raised below through a three-way pipe, connecting pipe, and dust suction hood, drawing the dust into the collection box for collection. By lifting the insert block, the collection box is pulled out of the fixed box, and the dust inside is emptied.

[0009] Preferably, a power supply box is connected to one end of the top of the vehicle body, and an observation port is provided at the other end of the top of the vehicle body, with a transparent window connected to the top of the observation port.

[0010] Power is supplied by a battery inside the power supply box, and a transparent window allows for easy observation of the cleaning mechanism below.

[0011] Preferably, both sides of the annular outer wall of the fixed plate are fixed with fixed plates, and the top of one of the fixed plates is connected and fixed to the bottom of the guide rod, and the fan is installed on the top of the other fixed plate.

[0012] The guide rod and the fan are installed and fixed by two fixed plates.

[0013] Preferably, the top of the vehicle body has a screw hole adapted to the handle screw, and the top of the vehicle body has a through hole adapted to the guide rod.

[0014] Rotate the handle screw to slide along the through hole with the guide rod, adjusting the overall height of the cleaning mechanism.

[0015] Preferably, the fixing box is fixed to the bottom of the vehicle body, and the bottom of the fixing box is provided with a ventilation hole. U-shaped blocks are fixed to one side of the outer wall of the collection box and the fixing box, and insert blocks are inserted into the two U-shaped blocks. Sealing sheets are glued to the other side of the outer wall and the top of the collection box, and a ∧-shaped filter screen is fixed to the bottom of the collection box.

[0016] The fan draws dust into the fixed box and then into the collection box. The airflow is then discharged through the vent below. After the collection box is inserted into the fixed box, the collection box and the fixed box are connected and fixed by insert blocks, and the sealing plate improves the sealing between the collection box and the fixed box.

[0017] Preferably, connecting frames are fixed on both sides of the annular outer wall of the fixed disk, and the connecting frames are inserted and fixed to the connecting pipe.

[0018] The connecting pipe is fixed by the set connecting bracket.

[0019] Preferably, a servo motor is installed at the bottom of the fixed plate, and the output shaft of the servo motor and the rod wall of the rotating rod are both fitted with meshing gears, and the bottom of the mounting plate is connected with bristles that are evenly distributed along a ring.

[0020] A servo motor drives a rotating rod to rotate via meshing gears. The rotating mounting plate drives the grinding plate to rotate and remove the markings. During the removal process, the mounting plate drives the brush bristles to rotate, which can remove stones from the road surface in advance.

[0021] The beneficial effects of this utility model are as follows:

[0022] By turning the handle screw, the height of the cleaning mechanism is adjusted, bringing the grinding disc below closer to the road marking. The grinding disc rotates to remove the road marking. During the cleaning process, the mounting plate drives the brush bristles to rotate, expelling stones from the road surface in advance. Then, a blower, through a T-pipe, connecting pipe, and dust suction hood, sucks up the dust raised below and collects it in the collection box. This effectively solves the problems of existing technologies where it is difficult to observe the cleaning status of the road marking and where dust is easily generated during the scraping process, affecting visibility and potentially causing respiratory hazards.
