Travel wheels 11 are installed at the bottom of the housing 1. The travel wheels 11 can be universal wheels or other structural wheels, which can be appropriately adjusted according to the actual working conditions for movement. A hand push rod 12 is installed at the top of the housing 1 and near one end. During construction, the staff can operate through the hand push rod 12.

[0046] Referring to Figure 1 , the lifting assembly 3 includes a driving motor 31, a screw rod 32, a slider 33, and a guide rod 34. The driving motor 31 is installed on the outer wall of the top of the housing 1, and the output shaft of the driving motor 31 passes through the housing 1 to its interior. The screw rod 32 is rotatably connected between the inner top wall and the inner bottom wall of the housing 1 through bearings, and one end of the screw rod 32 is fixedly connected to the output shaft of the driving motor 31. The slider 33 is threadedly connected to the screw rod 32, and the power assembly 4 is installed on one side of the slider 33. The guide rod 34 is arranged on the side of the screw rod 32 close to the hand push rod 12 and is parallel to the screw rod 32. Both ends of the guide rod 34 are fixedly connected between the inner top wall and the inner bottom wall of the housing 1 and pass through the slider 33. When the driving motor 31 is started, the slider 33 can slide up and down along the guide rod 34.

[0047] The power assembly 4 includes a box body 41, a brake motor 42, a driving gear 43, a driving shaft 44, and a driven gear 45. The interior of the box body 41 has a hollow structure, and a door convenient for maintenance can be provided on one side. The box body 41 is fixedly connected to the side of the slider 33 away from the guide rod 34. To increase the structural strength, a reinforcing plate 46 is welded between the slider 33 and the box body 41. The brake motor 42 is installed inside the box body 41, and the output shaft of the brake motor 42 passes downward through the box body 41 to the outside; the driving gear 43 is fixedly connected to the rod body whose output shaft passes through the box body 41 to the outside. The driving shaft 44 is rotatably connected inside the box body 41 through bearings, and the bottom end of the driving shaft 44 sequentially passes through the box body 41 and the housing 1 and is detachably and fixedly connected to the grinding disc 2; the driven gear 45 is fixedly connected to the rod body of the driving shaft 44 passing through the box body 41 to the outside and meshes with the driving gear 43.

[0048] When the brake motor 42 is started, the driving shaft 44 rotates at a high speed driven by the driving gear 43 and the driven gear 45, thereby driving the grinding disc 2 to rotate; after the brake motor 42 stops, the driving shaft 44 stops rotating and cannot rotate freely.

[0049] Referring to Figure 1 and Figure 2, a connection component 6 is provided between the drive shaft 44 and the grinding disc 2 for connecting the two.

Mounting holes corresponding to the threaded rod members 63 one by one are machined on the lower seat 62. The connection component 6 further includes a nut 64. During installation, the threaded rod members 63 are aligned with the mounting holes and inserted, and then locked and fixed by the nut 64. Since the grinding disc 2 will be worn after being used for a period of time, it needs to be replaced regularly. With the above-mentioned connection component 6, during disassembly, only the nut 64 needs to be rotated, without the need to prevent the bolt from rotating while rotating the nut 64 as in the disassembly of traditional bolts, which is more convenient to operate.

When the spring 76 is in a normal state, part of the clamping block 75 extends out of the mounting groove 74. For the convenience of installation, the end of the clamping block 75 away from the spring 76 is designed as a spherical surface.

[0054] During installation, the clamping block 75 is pressed into the mounting groove 74, and then the connecting rod 72 is inserted into the fixed cylinder 71. When the clamping block 75 moves to the corresponding fixing hole 73 along with the connecting rod 72, the clamping block 75 pops out under the action of the spring 76 and is clamped into the fixing hole 73 to achieve fixation.

[0055] The implementation principle of the embodiment of the present application is as follows: During operation, the cleaning device is moved to a specified position, and then the driving motor 31 is started to adjust the position of the grinding disc 2. After the grinding disc 2 is in place, the brake motor 42 is started, so that the driving shaft 44 rotates at a high speed driven by the driving gear 43 and the driven gear 45, and then drives the grinding disc 2 to rotate to perform the cleaning operation on the road marking. At the same time, the water pump 52 is started, so that the water in the water tank 51 is pumped into the water distribution pipe 53 and then sprayed out through the spray head 57 to suppress dust and cool the grinding disc 2 at the same time. According to needs, two cleaning devices can be operated simultaneously through the linkage assembly 7, greatly improving the operation efficiency.
