The specific intelligent sensing guardrail cleaning operation mode is as follows:
firstly, the guardrail is cleaned by one-key action, as shown in figure 5,
and (I) the driver adjusts the distance between the guardrail cleaning vehicle and the guardrail.
And (II) starting the one-key rolling sweeping action, controlling the front swing arm 2 and the rear swing arm 2 to extend the internal and external rolling sweeping devices out of the vehicle, and stopping the swing arm oil cylinder 3 when a travel switch at the swing arm senses the internal and external rolling sweeping devices. Firstly, the outer rolling brush telescopic oil cylinder 8 extends for a certain distance, if: stopping after 100mm, and then turning the outer rolling sweeper by 90 degrees through the outer rolling sweeper turning oil cylinder, and then sensing that the outer rolling sweeper is turned by 90 degrees through the turning proximity switch.
And thirdly, the oil cylinder of the rear swing arm 2 continuously pushes the front swing arm 2 and the rear swing arm 2 to extend out (a time relay is adopted to control the swinging time of the swing arm oil cylinder 3). After the time of the swing arm is over, the inner and outer rolling sweeping telescopic oil cylinders of the upper and lower telescopic arms at the telescopic arm are controlled to simultaneously extend out (the time of the outer rolling sweeping oil cylinder extending out is controlled by a time relay), and when the sensing device 30 at the inner rolling brush assembly 11 contacts the guardrail, the inner rolling sweeping telescopic oil cylinder of the lower telescopic arm stops extending out.
And (IV) after the outer rolling-sweeping telescopic oil cylinder of the telescopic upper arm continuously extends to a critical value.
And (V) controlling the outer rolling sweep overturning oil cylinder to overturn the outer rolling sweep back by 90 degrees to an initial state (at the moment, the reset proximity switch senses).
And (VI) finally, retracting the outer rolling sweeper telescopic oil cylinder, so that the inner and outer rolling sweeper devices clamp the guardrail in the middle when the induction switch at the outer rolling sweeper part is in contact with the guardrail. The ultrasonic sensor installed at this time records that the distance between the fixed values of the inner and outer rolling brushes is set as an initial value, and then the rolling brush motor 16 and the water pump are started to perform the guardrail rolling brush and guardrail cleaning actions.
Secondly, automatically adjusting the distance between the rolling brushes: when the guardrail rolling brush device is used for cleaning the guardrail along with the advancing of a vehicle, the conditions of running deviation of the vehicle and width change of the guardrail can occur, and the guardrail cleaning device can automatically adjust the distance between the rolling brush and the guardrail according to the conditions of running deviation of the vehicle and width change of the guardrail, and the detailed description is as follows:
2.1 when the guardrail cleaning process, the vehicle is deviated: 1) when the vehicle runs, the inner rolling brush assembly 11 is close to the guardrail, and the outer rolling brush assembly 13 deviates from the guardrail; at this time, the offset sensing contact 31 on the sensing device 30 of the inner rolling brush assembly 11 contacts with the guardrail, when the contact generates inward extrusion force, the sensor fixing plate 33 compresses the offset spring 35 to move inward, so as to avoid the damage of the device, and at the same time, when the offset sensing contact 31 senses the contact with the guardrail, a signal is transmitted to the controller, the controller gives an instruction to the inner rolling brush telescopic cylinder 7 to move inward until the offset sensing contact 31 is not in contact with the guardrail, and simultaneously, the distance between the inner rolling brush fixing frame 14 and the outer rolling brush fixing frame 14 is changed due to the inward movement of the inner rolling brush assembly 11 under the pushing of the inner rolling brush telescopic cylinder 7, which directly affects that the outer rolling brush assembly will deviate from the guardrail, at this time, the ultrasonic sensor transmits the change value to the controller, so that the outer rolling brush telescopic cylinder 8 moves inward, so as to reach the initial value set by the ultrasonic sensor (for example, the distance between the inner rolling brush fixing frame 14 and the outer rolling brush fixing frame is 400mm, the inner rolling brush assembly 11 moves 50mm towards the inner side, the distance between the inner rolling brush fixing frame and the outer rolling brush fixing frame 14 at the moment is 450mm, the outer rolling brush telescopic oil cylinder 8 drives the outer rolling brush assembly 13 to move 50mm towards the inner side, the distance between the inner rolling brush assembly and the outer rolling brush assembly is kept unchanged, and the distance between the inner rolling brush assembly 13 and the guardrail is always kept to be a rated value).
2) When the vehicle runs and the inner rolling brush assembly 11 deviates from the guardrail, the outer rolling brush assembly 13 approaches the guardrail; at this moment, the offset sensing contact 31 on the sensing device 30 of the outer rolling brush combination 13 is contacted with the guardrail, when the contact generates outward extrusion force, the sensor fixing plate 33 is enabled to compress the offset spring 35 to move inwards to avoid the damage of the device, meanwhile, when the offset sensing contact 31 senses the contact with the guardrail, a signal is transmitted to the controller, the controller issues an instruction to move the outer rolling brush telescopic oil cylinder 8 outwards until the offset sensing contact 31 is not contacted with the guardrail, meanwhile, the distance between the inner rolling brush fixing frame and the outer rolling brush fixing frame 14 is changed due to the outward movement of the outer rolling brush combination 13 under the pushing of the outer rolling brush telescopic oil cylinder 8, the direct influence is that the offset guardrail is deviated by the inner rolling brush combination, at the moment, the ultrasonic sensor transmits the change value to the controller, so that the outer rolling brush telescopic oil cylinder 8 moves inwards, and the initial value set by the ultrasonic sensor is reached
3) When the vehicle running deviation exceeds a rated value, in the state that the deviation spring 35 is compressed at the deviation sensor 34 to trigger a rated pressure value, the deviation sensor 34 on the inner and outer rolling brush assemblies 13 feeds back different signals to the controller, and the controller outputs the signals to a direction sensor in a cab to prompt a driver to control a steering wheel to adjust the distance between the steering wheel and a guardrail. The deviation sensor 34 of the sensing device 30 of the inner rolling brush assembly 11 prompts the driver to operate the steering wheel of the vehicle to return to the right side in the driving process, and the deviation sensor 34 of the sensing device 30 of the outer rolling brush assembly 13 prompts the driver to operate the steering wheel of the vehicle to return to the left side in the driving process
2.2 when guardrail cleaning process, guardrail width suddenly increases: what width modulation response contact 31 adopted is that the titanium alloy pole is connected the design with the response electric shock, and the guardrail is when getting an electric shock with the width modulation response, because the width modulation response is got an electric shock small, the quality is light, the pliability is strong, can not produce great impact force when the contact and damage induction system 30, and the reconversion that can be quick when separating with the guardrail is indeformable simultaneously, has effectively improved life.
When the width adjustment sensing contact 31 at the foremost end of the guardrail device senses a wider guardrail, different output signals are fed back to the controller through the sensing contacts 31 at different positions, so that different output signals are fed back according to the contact feedback change values of the guardrail with the sensing contacts 31 at different widths, the stretching amount of the outer rolling brush stretching oil cylinder 8 and the inner rolling brush stretching oil cylinder 7 is controlled, and the distance between the rolling brush device and the guardrail is controlled to be kept unchanged. (for example, the distance between the initial inner and outer rolling brush holders 14 is 400mm, the guardrail width at this time is 100mm, when the guardrail width is increased to 200mm, the width adjusting sensor on the inner and outer rolling brush assembly 13 is simultaneously spaced from the guardrail to transmit signals, and the inner and outer rolling brush telescopic cylinders 8 are adjusted to respectively operate the inner and outer rolling brushes to move inwards and outwards, so that the distance between the inner and outer rolling brush holders 14 is changed to 500 mm), after the distance between the inner and outer rolling brush holders 14 is increased and the guardrail is widened, the inner and outer rolling brush cylinders are adjusted to respectively adjust towards the initial value direction by delaying for a few seconds through a time relay, so that the distance between the inner and outer rolling brush holders 14 is restored to the initial value, if the deviation sensor comes into contact with the guard rail during the recovery process, the deviation will be stopped, and the sensing of the deviation sensor in the first or second step is repeated, and meanwhile, after delaying for a few seconds, the inner and outer rolling brushes continue to move towards the initial value direction and finally reach the initial distance value.
Adjustment of the sensing device 30: the contact area between the round brush and the guardrail when the guardrail of co-altitude and required induction system 30 senses the guardrail is adjusted through induction system mount 31 of fixed induction system 30, the height adjustment is carried out around spray lance and fixed orifices on the combination 13 of the inner and outer round brush, the distance is adjusted about a plurality of mounting holes 37 that set up at induction system mount 31, satisfy the best round brush cleaning contact area to the guardrail of co-altitude and width.
Thirdly, adjusting the rotating speed of the automatic rolling brush motor 16, adjusting the vehicle speed and adjusting the rotating speed of the water pump:
3.1 automatic rolling brush motor 16 speed regulation: as the inner and outer rolling brush assemblies 13 are closer to each other, the contact area between the inner and outer rolling brushes is increased, the generated resistance is larger, the high-speed running condition of the rolling brush motor 16 is kept, the quick abrasion of the sweeping brush is caused, the service life of equipment and guardrails is influenced, and the rotating speed of the rolling brush motor 16 needs to be adjusted according to the distance between the inner and outer rolling brush fixing frames 14.
The distance between the inner and outer rolling brush fixing frames 14 sensed by the ultrasonic sensor is adopted, signals are fed back to the controller according to different distances, and different values are transmitted to the electric proportional throttle valve of the rolling brush motor 16 according to different signals to adjust the rotating speed of the rolling brush motor 16.
1) When the inner and outer rolling brush combination 13 is just tangent, the guardrail cleaning device can clean the widest state of the guardrail, the distance between the inner and outer rolling brush fixing frames 14 is 530mm, and the width of the washable guardrail is 0-290 mm
2) When the maximum critical value of the contact area of the inner and outer rolling brush combination 13 is reached, the contact area between the inner and outer rolling brushes reaches two thirds of the width of the sweeping brush, the distance between the inner and outer rolling brush fixing frames 14 is 390mm, and the width of the washable guardrail is 0-200 mm
3) The rotating speed of the rolling brush motor 16 is gradually reduced from the set highest rotating speed to the set lowest rotating speed within the range of 530 mm-390 mm between the inner and outer rolling brush fixing frames 14.
Vehicle speed regulation: when the distance between the inner and outer brush holders 14 is small, the contact area between the inner and outer brushes is large, and it is necessary to reduce the speed of the vehicle in addition to reducing the rotational speed of the brush motor 16. On the one hand, the impact force between the guardrail and the rolling brush is slowed down, and on the other hand, the guardrail can be ensured to be cleaner.
As shown in fig. 6, the approach taken to this is to install a secondary reduction transfer case 50 between the drive shaft 60 between the chassis gearbox and the rear axle. The speed ratio of the reduction gear is 1:2, and the gear shifting mode of the transfer case 50 is controlled by adopting cylinder pushing;
1) when the distance between the inner and outer rolling outer fixing frames is in the range of 450-530 mm, the vehicle guardrail can be kept to be cleaned quickly, and the secondary speed reduction transfer case 50 is not combined and is suitable for the condition that the guardrail is cleaner;
2) when the distance between the inner and outer rolling outer fixing frames is within the range of 390-450 mm, the air cylinder pushes the two-stage deceleration transfer case 50 to be combined, the running speed of the vehicle is reduced by one time, and the vehicle is suitable for the dirty state of the guardrail.
Adjusting the rotating speed of the water pump: the waterway system is provided with 2 water pumps which are respectively a high-pressure water pump and a direct-current water pump, the high-pressure water pump is driven by an auxiliary engine, a driver needs to select a guardrail cleaning mode according to the requirement of cleaning a road guardrail due to different cleaning rates of the guardrail, the direct-current water pump or the high-pressure water pump is selected in an electric control box panel of a cab, and the adjustment of the high-pressure water pump is realized by adjusting the rotating speed of the auxiliary engine.
The utility model adopts the above technical scheme, what intelligent operation that intelligent perception guardrail washs car mainly centers on is guardrail belt cleaning device's intelligent induction system 30, thereby realizes real-time regulation and control with the change of guardrail interval through induction system 30's sensor perception round brush, can make corresponding action according to the different output signal of the numerical value feedback difference of sensing of difference, effectively avoids because of round brush and guardrail interval change the damage and the influence of guardrail cleaning performance to the mechanism that causes. Meanwhile, humanized operation is provided for one-key cleaning action of the guardrail cleaning device, so that the operation of a driver is more convenient and safer.
