[0002] The grinding type road marking erasing device is currently the most widely used equipment in the process of municipal road maintenance. The traditional grinding type road marking erasing device sets the grinding block at the bottom of the frame, and the frame is provided with a power device for driving the grinding block to rotate at high speed. Then the frame is pushed manually or the frame is connected to the walking device. During the movement of the entire equipment, the worn road markings are erased by the high-speed rotating grinding block.

[0003] Chinese patent CN108385490B discloses a marking grinding device for municipal road construction.

[0025] like Figure 1 As shown, the present application discloses a road marking removal device, which includes a shell 1, a first grinding piece 2, a first rotating mechanism, a second rotating mechanism, a second grinding piece 3 and a moving mechanism, the first rotating mechanism, the second rotating mechanism and the moving mechanism are all arranged in the shell 1, and the first grinding piece 2 and the second grinding piece 3 are arranged at the bottom of the shell 1.

[0026] Specifically, the first grinding piece 2 is a grinding disc for grinding road markings, and a through hole 12 is provided in the middle of the first grinding piece 2 along the axial direction of the first grinding piece 2. The through hole 12 is provided with a first rotating mechanism, which includes a rotating tube 4 and a first rotating assembly for driving the rotating tube 4 to rotate. One end of the rotating tube 4 is fixedly arranged on the through hole 12, and the rotating tube 4 is connected to the through hole 12, and the other end of the rotating tube 4 is fixedly connected to the first rotating assembly. The first rotating assembly includes a first driving motor 5, a driving gear 6 and a driven gear 7. The output end of the first driving motor 5 is fixedly connected to the driving gear 6, the driving gear 6 is meshed with the driven gear 7, and the driven gear 7 is fixedly sleeved on the rotating tube 4. The first driving motor 5 drives the driving gear 6 to rotate, the driving gear 6 drives the driven gear 7 to rotate, and the driven gear 7 drives the rotating tube 4 to rotate, and the grinding piece rotates with the rotating tube 4. Under the rotation of the grinding piece, conventional road markings can be polished to achieve the removal of conventional road markings.

[0027] In order to solve the unconventional problem that the road markings in the road depressions are difficult to remove, in the present embodiment, a relatively small second grinding piece 3 is arranged in the through hole 12, and the road markings in the road depressions are removed by the second grinding piece 3. Specifically, the second grinding piece 3 passes through the through hole 12, and the second grinding piece 3 is movably connected to the through hole 12, and the second grinding piece 3 can move and rotate in the through hole 12. The second grinding piece 3 is driven to rotate by the second rotating mechanism. The second rotating mechanism includes a rotating rod 8 and a second rotating assembly that drives the rotating rod 8 to rotate. One end of the rotating rod 8 passes through the rotating tube 4 and extends to the through hole 12. The rotating rod 8 is movably connected to the rotating tube 4, so that the rotating rod 8 can move or rotate relative to the rotating tube 4. The second rotating assembly includes a second drive motor 9 and a coupling 10. The output end of the second drive motor 9 is fixedly connected to the coupling 10, and the end of the coupling 10 away from the second drive motor 9 is fixedly connected to the rotating rod 8. The second driving motor 9 drives the rotating rod 8 to rotate through the coupling 10, and drives the second polishing member 3 to rotate through the rotating rod 8, thereby realizing the rotation of the second polishing member 3. Furthermore, a moving mechanism is provided on the second driving motor 9, and the moving mechanism is used to drive the second rotating mechanism and the second polishing member 3 to move. Specifically, the moving mechanism includes a moving cylinder 11, and the output end of the moving cylinder 11 is fixedly connected to the second driving motor 9. When it is necessary to clear the road markings in the road depression, the moving cylinder 11 drives the second polishing member 3 to move through the second driving motor 9 and the rotating rod 8, so that the bottom of the second polishing member 3 moves out of the through hole 12 and extends into the road depression, and then the rotating rod 8 is driven to rotate by the second driving motor 9, and the second polishing member 3 is driven to rotate by the rotating rod 8, and the road markings in the road depression are cleared by the second polishing member 3, thereby realizing the cleaning of the road markings in the road depression.

[0028] Furthermore, in order to improve the stability and smoothness of the movement of the rotating rod 8 in the rotating tube 4, in this embodiment, a bearing is further included, which is arranged in the rotating tube 4 and slidably connected to the rotating tube 4, and the bearing is fixedly sleeved on the rotating rod 8. The outer ring of the bearing is connected to the rotating tube 4, and the inner ring of the bearing is fixedly connected to the rotating rod 8, so that the rotating rod 8 can rotate relative to the rotating tube 4, and the bearing is slidably connected to the rotating tube 4, so that the rotating rod 8 can move relative to the rotating tube 4, which is convenient for controlling the rotating rod 8.

[0029] Furthermore, in order to reduce the friction between the bearing and the rotating tube 4, in this embodiment, a slip ring is further included, and the slip ring is arranged between the bearing and the rotating tube 4. Specifically, a sliding groove is provided on the inner side wall of the rotating tube 4, and the slip ring is arranged in the sliding groove and is slidably connected with the sliding groove. The slip ring can slide in the sliding groove, and the slip ring is fixedly sleeved on the outer ring of the bearing. The slip ring reduces the friction between the bearing and the rotating tube 4, so that the rotating tube 4 moves more smoothly on the rotating tube 4, and can reduce the friction loss between the bearing and the rotating tube 4.

[0030] When in use, first use the first drive motor 5 to drive the active gear 6 to rotate, the active gear 6 then drives the driven gear 7 to rotate, the driven gear 7 then drives the rotating tube 4 to rotate, the grinding piece follows the rotating tube 4 to rotate, and under the rotation of the grinding piece, the conventional road markings are polished to achieve the removal of the conventional road markings, and then control the moving cylinder 11 to drive the second grinding piece 3 to move through the second drive motor 9 and the rotating rod 8, so that the bottom of the second grinding piece 3 moves out of the through hole 12 and extends into the road depression, and then the second drive motor 9 drives the rotating rod 8 to rotate, and the rotating rod 8 drives the second grinding piece 3 to rotate, and the second grinding piece 3 is used to remove the road markings in the road depression, so as to achieve the cleaning of the road markings in the road depression.

[0031] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
