Technical Field

[0001] This utility model relates to the field of guardrail cleaning technology, and in particular to a cleaning device for road and bridge guardrails. Background Technology

[0002] Road and bridge guardrails are safety protection facilities installed on both sides of roads or bridges. Their main function is to protect traffic safety, prevent accidents involving pedestrians or vehicles, and avoid serious losses in the event of an accident. They not only play a protective role but also improve the aesthetics of roads. However, due to the frequent passage of vehicles, roads and bridges usually accumulate a lot of dust, which causes the guardrails to become dusty. Therefore, regular cleaning of the guardrails is necessary.

[0003] In existing technologies, the road and bridge guardrail cleaning devices typically use brushes in conjunction with water sprayers to clean the guardrails. However, this cleaning method usually only cleans a single surface of the guardrail and cannot achieve a comprehensive cleaning, resulting in incomplete cleaning. Utility Model Content

The drive motor is then started. 6. Start rotating the brush 31 and simultaneously turn on the water spray head 331. Since the water spray head 331 is located between the two brushes 31, during the cleaning process, the brush 31 on the front side can remove the debris on the railing for the first time. Then, the water spray head 331 sprays water to rinse the railing that has been initially cleaned. The brush 31 on the rear side then performs a second cleaning to remove excess water stains and remaining debris from the railing. Finally, the blower 8 and the air nozzle 321 work together to air dry the railing, increasing the cleanliness of the entire device when cleaning the railing.

[0023] Specifically, the drive mechanism includes a forward and reverse motor 5 fixedly installed on the upper surface of the lifting platform 2.

The interior of the mounting plate 1 3 has a movable groove that matches the positioning rod 7.

[0024] In this embodiment, a drive mechanism for mounting plate 2 4 is provided at the upper end of the lifting platform 2. When the mounting plate 2 4 needs to be moved, the forward and reverse motor 5 is first started by the control console 12. Under the action of the forward and reverse motor 5, the one-way screw 51 can be rotated, thereby moving the connecting piece 52 screwed on the outer surface of the one-way screw 51, and then moving the mounting plate 2 4. This allows the distance between the mounting plate 2 4 and the mounting plate 3 to be adjusted to suit different guardrails. The positioning rod 7 provided on the side surface of the mounting plate 2 4, together with the movable groove opened inside the mounting plate 3, can prevent the mounting plate 2 4 from shifting during the movement.
