[0026] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 8 The utility model provides a technical solution: a municipal road cement pavement cleaning device.

[0028] In embodiment 1, a mounting bracket 2 is fixed at the bottom of the cleaning vehicle base 1, and a motor 4 is fixed inside the mounting bracket 2. The motor 4 is the power source for the rotation of the friction wheel 3. A storage rod 6 is fixed at the output end of the motor 4. A support bracket 7 is movably inserted at the bottom of the mounting bracket 2. A limiting ring 8 is fixed at the end of the support bracket 7. The rotation of the limiting ring 8 will drive the telescopic rod 9 to move downward.

[0029] A baffle 21 is fixed to the upper end of the telescopic rod 9, and an inner groove 22 is opened inside the baffle 21. A telescopic block 25 is movably provided on the inner wall of the inner groove 22. The upper end of the telescopic block 25 contacts the lower end of the stopper 14, so the vertical force of the limit block 13 on the movable collar 18 is very large. Under the restriction of the stopper 14, the telescopic rod 9 will not move upward. A movable collar 18 is movably provided on the outer surface of the telescopic rod 9, and a friction wheel 3 is fixed to the lower end of the telescopic rod 9.

[0030] On the basis of embodiment 1, in order to achieve the stability of the friction wheel 3 in cleaning the road surface, a storage groove 15 is opened inside the storage rod 6, a notch 17 is opened near the end of the storage groove 15, a block 14 and a slide rail 16 are fixed to the inner wall of the storage groove 15, and a baffle 21 is movably clamped on the inner wall of the storage groove 15.

[0031] A through slot 10 is provided at the bottom of the mounting bracket 2, a positioning block 11 is fixed to the inner wall side surface of the through slot 10, and a positioning slot 12 is provided on the side surface of the supporting bracket 7. The positioning block 11 corresponds to the positioning slot 12 and is clamped and movably connected, which plays a positioning role for the mounting bracket 2 to rotate in the through slot 10, and also plays a supporting role for the limiting ring 8.

[0032] The limiting collar 8 is located on the outer surface of the storage rod 6 and is not connected. The limiting block 13 is fixed to the inner wall of the limiting collar 8, and a limiting groove 19 is provided on the outer surface of the movable collar 18. The limiting block 13 corresponds to the limiting groove 19 and is clamped, and is movably connected. Since the limiting block 13 is clamped with the limiting groove 19, and the two ends of the limiting groove 19 are at different heights, the rotation of the limiting collar 8 will drive the limiting block 13 to move toward the higher end in the limiting groove 19. Since the height of the limiting block 13 is fixed, the movable collar 18 will drive the telescopic rod 9 to move downward, thereby driving the friction wheel 3 to move downward, so that the friction wheel 3 contacts the ground again, thereby achieving stability of the friction wheel 3 when cleaning the road surface.

[0033] A sliding groove 20 and a movable groove 23 are provided on the outer surface of the baffle 21. An inner groove 22 is provided on the inner wall of the movable groove 23. A second spring 24 is provided on the inner wall of the inner groove 22. When the telescopic block 25 is retracted into the inner groove 22 and the telescopic block 25 is no longer restricted, the second spring 24 will support the telescopic block 25 to return to its original position. A telescopic block 25 is provided at the end of the second spring 24.

[0034] The slide groove 20 corresponds to and is locked with the slide rail 16, and is movably connected to form a limit between the telescopic rod 9 and the storage rod 6, so that when the motor 4 drives the storage rod 6 to rotate, it can be locked with the slide rail 16 through the slide groove 20, thereby driving the telescopic rod 9 to rotate. The telescopic block 25 is located between the two groups of blocks 14. The upper and lower ends of the block 14 and the telescopic block 25 are flat, and the side surface where the block 14 contacts the telescopic block 25 is an inclined surface.

[0035] A baffle is fixed on the surface of the mounting bracket 2 near the through slot 10 , and a first spring 5 is provided between the supporting bracket 7 and the baffle. The first spring 5 will support the supporting bracket 7 so that it rotates in the through slot 10 along the positioning block 11 .

[0036] In actual use, when the friction wheel 3 is no longer in contact with the ground due to wear and tear from long-term work, there is no restriction of the ground at this time. The first spring 5 will support the support bracket 7 to make it rotate along the positioning block 11 in the through groove 10. The rotation of the support bracket 7 will drive the limiting collar 8 to rotate. Since the limiting block 13 is clamped with the limiting groove 19, and the two ends of the limiting groove 19 are at different heights, the rotation of the limiting collar 8 will drive the limiting block 13 to move toward the higher end in the limiting groove 19. Because the height of the limiting block 13 is fixed, the movable collar 18 will drive the telescopic rod 9 to move downward, thereby driving the friction wheel 3 to move downward, so that the friction wheel 3 contacts the ground again, thereby achieving the stability of the friction wheel 3 when cleaning the road surface, and limiting The slope of the positioning groove 19 is very large, so the limit block 13 moves in the limit groove 19. The horizontal force on the movable collar 18 is very small, and the vertical force on it is very large. Therefore, the movement of the limit block 13 will not cause the movable collar 18 to rotate. At the same time, the end of the telescopic block 25 and the stopper 14 are flat, and the upper end of the telescopic block 25 contacts the lower end of the stopper 14. Therefore, the vertical force of the limit block 13 on the movable collar 18 is very large. Under the restriction of the stopper 14, the telescopic rod 9 will not move upward. Due to the inclined surface of the telescopic block 25 in contact with the side of the stopper 14, the telescopic block 25 will be restricted by the stopper 14 when it moves downward, so that the telescopic block 25 is retracted into the inner groove 22, so the telescopic block 25 will not limit the downward movement of the telescopic rod 9.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
