The distance between the roller brush and the guard rail 37 will be affected by deviations in the travel of the vehicle and variations in the width of the guard rail 37.

When the guardrail 37 is cleaned, the width of the guardrail 37 is suddenly increased:

And through contact response guardrail 37, whole process response is accurate, and the error is little, and greatly reduced driver is to the operability of 2 interval modulation of round brush mechanism, and in 2 adjustment range of round brush mechanism, the driver need not to adjust round brush mechanism, realizes the full-automatic round brush washing of guardrail 37 cleaning process.

Secondly, when the guardrail 37 is cleaned, the vehicle is deviated:

(1) when the vehicle travels with the first rolling brush means 21 approaching the guard rail 37 and the second rolling brush means 22 being offset from the guard rail 37. At this time, the offset contact 34 on the first transition sliding block 32 contacts with the guardrail 37, a signal is fed back to the control mechanism 4, and the control mechanism 4 controls the first telescopic cylinder 114 to contract inwards, so that the distances between the first rolling brush mechanism 21 and the guardrail 37 and the distances between the second rolling brush mechanism 22 and the guardrail 37 are kept unchanged, an optimal distance is kept, and a better cleaning effect is achieved. Meanwhile, the first transition sliding block 32 is pressed inwards by the lateral pressure generated when the offset contact 34 is in contact with the guardrail 37, and at the moment, the first obstacle avoidance spring 31 is compressed to avoid the damage of the first transition sliding block 32.

(2) When the vehicle travels with the first rolling brush means 21 offset from the guard rail 37 and the second rolling brush means 22 close to the guard rail 37. At this time, the offset contact 34 on the second transition sliding block 36 contacts with the guardrail 37, and feeds back a signal to the control mechanism 4, and the control mechanism 4 controls the second telescopic cylinder 124 to extend outwards, so that the distances between the first rolling brush mechanism 21 and the guardrail 37 and the distances between the second rolling brush mechanism 22 and the guardrail 37 are kept unchanged, an optimal distance is kept, and a better cleaning effect is achieved. Meanwhile, the second transition sliding block 36 is extruded outwards by the lateral pressure generated when the offset contact 34 is in contact with the guardrail 37, and at the moment, the second obstacle avoidance spring 35 is compressed to avoid the second transition sliding block 36 from being damaged.

(3) When the vehicle running deviation exceeds a set rated value, the stretching amount of the first stretching oil cylinder 114 and the second stretching oil cylinder 124 exceeds the stroke regulation, the first obstacle avoidance spring 31 is pressed inwards, the first limiting block 115 is pressed, the first force-sensitive sensor 117 transmits a signal to the control mechanism 4, the control mechanism 4 transmits the signal to the direction sensor 7 in the cab, and a driver is prompted to control the steering wheel to regulate the distance between the steering wheel and the guardrail 37. Or the second obstacle avoidance spring 35 is extruded outwards, the second limiting block 125 is stressed, the second force-sensitive sensor 127 transmits a signal to the control mechanism 4, and the control mechanism 4 transmits the signal to the direction sensor 7 in the cab to prompt a driver to control the steering wheel to adjust the distance between the steering wheel and the guardrail 37.

It should be noted that, although the above embodiments have been described herein, the scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, the changes and modifications of the embodiments described herein, or the equivalent structure or equivalent process changes made by the contents of the specification and the drawings of the present invention, directly or indirectly apply the above technical solutions to other related technical fields, all included in the protection scope of the present invention.
