Description

Technical Field

[0001] This utility model relates to a road maintenance equipment, specifically a road marking cleaning device. Background Technology

[0002] With the continuous development of transportation, road markings play a crucial role in guiding traffic and ensuring driving safety. However, prolonged exposure to vehicles, sun and rain, and especially the adhesion of vehicle exhaust pollutants in the relatively enclosed environment of tunnels, can reduce the reflectivity of road markings and decrease their reflectivity. Therefore, regular cleaning and replacement of road markings are necessary.

[0003] Currently, existing road marking cleaning methods mainly include manual cleaning and mechanical cleaning. Manual cleaning is inefficient, labor-intensive, and the cleaning effect is difficult to guarantee. Prolonged road work not only affects traffic flow but also increases safety risks; this method is particularly unsuitable for highway road marking cleaning. Simple mechanical cleaning equipment requires manual operation in exposed environments, increasing the risks of road work. Furthermore, most current marking cleaning equipment requires the simultaneous occupation of two lanes to clean the markings between them. Therefore, there is a need for a highly efficient, multifunctional, and environmentally friendly road marking cleaning device. Summary of the Invention

[0025] The present invention will be further explained below with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, a road marking cleaning device includes a fixing part, a left and right side switching part, a horizontal angle adjustment part, a vertical height adjustment part, and a cleaning component.

[0027] The fixing part consists of a main steel plate 101, two auxiliary steel plates 102, and four stiffening plates 103. The main steel plate 101 is fixedly connected to the center of the front of the vehicle's front anti-collision beam by bolts or welding, and is set perpendicular to the horizontal ground. The two auxiliary steel plates 102, which are arranged parallel to each other vertically, are vertically welded to the front of the main steel plate 101 by their bottom edges. The four stiffening plates 103 are symmetrically arranged between the two auxiliary steel plates 102 and the main steel plate 101, forming a high-strength main mounting frame structure. The two auxiliary steel plates 102 have symmetrical through holes 104 at the middle position in the horizontal direction, and the upper auxiliary steel plate 102 has two through holes 105 on both sides in the horizontal direction.

[0028] The left-right switching section consists of a crossbeam 201, a pivot 202, and a pin 203. The crossbeam 201 has an I-shaped cross-section, and its structural weight is reduced by intermittently drilling holes in the horizontal direction. The crossbeam 201 is positioned between two secondary steel plates 102 of the fixed section, and one end of the crossbeam 201 is rotatably connected to a set of through holes 104 between the two secondary steel plates 102 via the vertically positioned pivot 202. The crossbeam 201 can rotate around the pivot 202 to the left or right side of the vehicle's front, and the vertically positioned pin 203 passes through the through holes 105 on the left or right side of the upper secondary steel plate 102 and is inserted into the corresponding pin hole at the top of the crossbeam 201, thereby locking the position between the left-right switching section and the fixed section.

[0029] The horizontal angle adjustment unit consists of a semi-frame bracket 301, a hydraulic rod 302, and a rotating shaft 303. The semi-frame bracket 301 comprises parallel horizontal bars and vertical bars, each fixedly connected to one end of one of the two horizontal bars. The other ends of the two horizontal bars are hinged to the top and bottom surfaces of the free ends of the crossbeam 201 of the left and right switching section, respectively; a rotating shaft or other existing rotating connection structure can be used. The semi-frame bracket 301 achieves horizontal rotation around the free end of the crossbeam 201 through its hinged connection. The base of the hydraulic rod 302 is fixed to the top surface of the crossbeam 201, and the free end of the hydraulic rod 302 is hinged to the top of the semi-frame bracket 301 via the rotating shaft 303. By controlling the movement of the hydraulic rod 302, the free end of the hydraulic rod 302 drives the semi-frame bracket 301 to rotate horizontally around the free end of the crossbeam 201.

[0030] The vertical height adjustment unit consists of a semi-frame bracket II and a hydraulic rod II 401. The semi-frame bracket II comprises horizontal bars 402 and 403 and a vertical bar 404. The upper and lower ends of the vertical bar 404 are hinged to one end of each of the two horizontal bars, allowing the two horizontal bars to rotate within the vertical plane around the end of the vertical bar 404. The other ends of the two horizontal bars are hinged to the middle and lower parts of the vertical bars of the semi-frame bracket I 301 of the horizontal angle adjustment unit, respectively, allowing the overall center point of the semi-frame bracket II to move vertically relative to the horizontal angle adjustment unit within the vertical plane. A horizontal through slot is formed in the upper horizontal bar 402 of the semi-frame bracket II. The base of the hydraulic rod II 401 is fixed to the upper part of the vertical bar of the semi-frame bracket I 301, and the free end of the hydraulic rod II 401 passes through this horizontal through slot and is hinged to the lower horizontal bar 403 of the semi-frame bracket II. In this embodiment, the upper crossbar 402 and the lower crossbar 403 have the same length; the distance between the two hinge nodes of the upper crossbar 402 and the lower crossbar 403 that are hinged to the semi-frame bracket 301 is the same as the length of the vertical bar 404 of the semi-frame bracket; by setting these two dimensions, it is ensured that the vertical bar 404 always moves in a direction perpendicular to the ground, thereby realizing the height adjustment of the cleaning assembly installed on the vertical bar 404 in a direction perpendicular to the ground by driving the hydraulic rod 401.

[0031] The cleaning assembly consists of a roller brush 501, a nozzle assembly 502, a splash guard 503, a motor 504, and a support structure. The support structure comprises a support arm 505, a connecting flange 506, an L-shaped connecting plate 507, a flat connecting plate 508, and a U-shaped metal component 509. One end of the support arm 505 is bolted to the vertical rod 404 of the vertical height adjustment unit, and the other end is connected to the long side of the L-shaped connecting plate 507 via the connecting flange 506. The roller brush 501 is mounted on one side of the short side of the L-shaped connecting plate 507, and the motor 504 is fixed to the other side. The top of the short side of the L-shaped connecting plate 507 is connected to the middle of the bottom edge of the U-shaped metal component 509 via the flat connecting plate 508. The U-shaped metal component 509 is located above the roller brush 501, with both sides of the U-shaped metal component 509 parallel to the axis of the roller brush 501. The nozzle assemblies 502 are fixed to both sides of the U-shaped metal component 509. The top and sides of the U-shaped metal part 509 are provided with anti-splash baffles 503.

[0032] In this utility model, a road marking cleaning device has a fixed part that is fixedly connected to the front bumper beam of a vehicle, providing a foundation for the device to be installed on the vehicle. This allows the cleaning component at the end of the device to move with the vehicle on the road, achieving the purpose of mechanized cleaning of the road markings. One end of the left-right switching part is connected to the middle position of the fixed part via a rotating shaft, and the two are locked together by a pin. By adjusting the left-right switching part to the left or right side of the vehicle's front, the cleaning component at the end of the device can be switched to the left or right side of the vehicle to clean the markings on both sides of the lane separately. This means that the cleaning component can clean the markings on the left or right side of the lane while traveling in one lane. The horizontal angle adjustment part is horizontally rotatably connected to the free end of the left-right switching part, and its rotation angle is controlled by a hydraulic rod, thereby enabling wide-angle adjustment of the cleaning component at the end of the device. The vertical height adjustment part is hinged to the horizontal angle adjustment part, and its vertical displacement is controlled by a hydraulic rod, thereby adjusting the height of the cleaning component above the road surface. The cleaning component is fixedly installed on the vertical height adjustment part for cleaning the road markings.

[0033] The motor in the cleaning assembly drives the roller brush to rotate via a transmission mechanism. The rotation speed can be steplessly adjusted via the motor's speed control device to improve cleaning effectiveness. The roller brush surface is equipped with bristles, the hardness and density of which can be adjusted according to the material of the road markings and cleaning requirements. A high-pressure water pump on the vehicle body is connected to the nozzle assembly via a water supply pipeline. The nozzle assembly is installed on both sides of a U-shaped metal component, arranged in double or multiple rows. The spray angle, spray pressure, and water mist pattern of the nozzles are adjustable to adapt to different types of road marking cleaning needs. A splash guard is installed on the U-shaped metal component to block dust, wastewater, and gravel stirred up by the roller brush and nozzles, reducing the impact on other road surfaces and vehicles.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
