The working principle and the process of the invention are as follows:
the invention adopts a system for controlling the expansion amount of a spring, namely a soft and hard support combination device, and a method for limiting the rotation angle amplitude of a cleaning mechanism, namely a support follow-up mechanism.
The working process of the system for controlling the expansion and contraction amount of the spring-soft and hard support combined device is as follows: when the highway guardrail cleaning vehicle normally works or passes through a gap, the length of a large spring connected with a lead screw is changed due to the change of the backpressure of the highway guardrail on a cleaning mechanism, a position sensor and a trigger switch control system on a controller mounting plate send signals according to the expansion amount of the large spring to control a motor to start or stop running, the motor drives the lead screw nut through a transmission gear, and the lead screw nut is fixed, and rotates and moves to realize the adjustment of the displacement amount of the lead screw; meanwhile, one end of the spring is connected with the lead screw through the guide pin, the other end of the spring is connected with the front support swing arm through the spring mounting barrel, the change of the length of the lead screw can also realize the change of the displacement of the spring, when the stress of the spring is overlarge and the expansion and contraction amount of the spring is close to the upper limit of the group of sensors, the sensors send instructions to control the action of the motor, so that the lead screw nut meshed with the lead screw rotates towards a certain direction to lengthen the lead screw, on the contrary, when the stress of the spring is small and the expansion and contraction amount of the spring is close to the lower limit of the group of sensors, the sensors send instructions to control the action of the motor, so that the lead screw nut meshed with the lead screw rotates towards the other direction to shorten the lead screw, and the change of the rotation direction of the lead screw nut is controlled by the motor to lengthen or shorten.
Usually, the extension and contraction of the spring are controlled to change within a narrow range, and the length change of the lead screw is supplemented to ensure the requirement of the change of the swing range of the supporting swing arm in work. The spring can not change with large displacement instantly, so that the support swing arm can not be pulled back quickly, the cleaning mechanism is prevented from being clamped when the cleaning vehicle passes through the gap, the cleaning mechanism of the guardrail cleaning vehicle is hinged with the support swing arm, the cleaning mechanism is adjusted by the buffer connected with the rear support swing arm to adapt to the surface change of the guardrail, and the adjusting function of the buffer increases the possibility that the cleaning mechanism is clamped when the cleaning vehicle passes through the gap.
Method for controlling the angular amplitude of the washing mechanism-the working process of the supporting follow-up mechanism is as follows:
in the cleaning working process of the cleaning vehicle, the movement track of the cleaning vehicle is approximately parallel to the guardrail, but the distance between the cleaning vehicle and the guardrail is possibly different, so that the relative swing angles of the front supporting swing arm and the rear supporting swing arm of the cleaning vehicle and the guardrail are possibly different, the cleaning work of the cleaning mechanism is kept to adapt to the change, the working range of the cleaning mechanism is in a range in the direction basically parallel to the vehicle running direction, and local adjustment and fluctuation can be realized.
In order to realize the follow-up relation between the corner of the supporting swing arm and the corner of the arc groove plate, the system drives a driving chain wheel and a driven chain wheel through the gear transmission formed by a fixed gear, a transition gear and a follow-up gear which are fixed on a mounting plate, and the driven chain wheel drives the arc groove plate to move so as to meet the requirement that when the swing angle of the front supporting swing arm and the rear supporting swing arm of the cleaning vehicle relative to the guardrail is changed, the cleaning work of the cleaning mechanism can also adapt to the change.
The arc groove plate is connected with a locking plate on the cleaning mechanism through an arc-shaped notch by a locking pin shaft, the arc groove plate is fixed with and driven by a driven driving chain wheel arranged on a rear support swing arm shaft, when the guardrail cleaning vehicle passes through a notch in work, the rotation angle of the cleaning mechanism is limited by the slotting space of the arc-shaped notch, and the possibility that the cleaning mechanism is damaged by being clamped is reduced; and in normal work, when the supporting swing arm swings, the swing motion drives the driven driving chain wheel through the follow-up mechanism, so that the position of the arc groove plate changes, the movable space position of the locking pin shaft in the arc groove also changes, and in the range of the movable space of the locking pin shaft, the swing of the cleaning mechanism is adjusted by the buffer connected with the rear supporting swing arm, so that the cleaning mechanism adapts to the change of the surface of the guardrail, and after the cleaning mechanism is used, the front supporting swing arm and the rear supporting swing arm are folded by loosening the locking pin and the fixing pin.
