Description

Technical Field

[0001] This application relates to the technical field of traffic public facilities, and particularly relates to a two-way running roller obstacle removal mechanism for a tidal lane robot. Background Art

[0002] The technology of the tidal lane robot guardrail is to plan tidal variable lanes on the basis of the original lane. The tidal lane robot guardrail can work automatically according to the traffic flow on the road or be remotely controlled by the on-duty police, and switch between two isolated double yellow lines, so as to realize the intelligence and automation of the tidal variable lane. At the same time, variable lane signs and LED indicator screens are set at intersections. When the "robot guardrail" changes lanes, the variable lane signs change synchronously, so as to realize the automatic control and intelligent management of the traffic guardrail under the limited road resources, and improve the safety and traffic efficiency of the road traffic.

[0003] At present, the application of tidal lane robots is becoming more and more extensive. In the prior art, the tidal lane robot uses rollers to increase the contact area with the ground. At the same time, the rollers have high wear resistance, which can improve the service life of the tidal lane robot as a whole, reduce the maintenance cost, and adapt to the physical changes of different road surfaces in bad weather. However, compared with the ordinary wheeled walking system, the roller walking system has a larger contact area with the ground and is more likely to adhere to dirt, leaves and particulate debris, etc. Since the roller walking system measures the walking distance by using the circumference of the roller's own rotation, and then controls the start or stop of the measured walking distance through the electronic control system, the debris adhered to the roller will directly affect the calculation of the rotation circumference, and then affect the moving accuracy of driving the guardrail sheet by the whole row of tidal lane robots, and it is easy to cause cumulative measurement errors; it will also affect the stability and safety of the tidal lane robot during driving, cause the tidal lane robot to stop running, and even trigger secondary traffic accidents.

[0004] Therefore, in view of the above problems, this application provides a two-way running roller obstacle removal mechanism for a tidal lane robot, which is installed on both sides of the coaxial roller. The obstacle removal mechanism is provided with structures such as a scraper, an elastic element, a positioning control rod, etc. A set of obstacle removal mechanisms are symmetrically installed on both sides of the coaxial roller in this application, which not only adapts to the movement of the tidal lane robot in different directions, but also has a positioning control rod for adjusting the elastic element built in the obstacle removal mechanism, so that the scraper can remove the debris on the roller surface while not affecting the normal operation of the tidal lane robot, keep the roller surface clean, improve the stability of the tidal lane robot during operation and the service life of the roller itself, and adapt to different working requirements of the tidal lane robot.
