Description
Technical field
The utility model relates to a kind of sprinkling control systems more particularly to a kind of new application to spill in the semi-automatic of road roller
Water control system.
Background technique
In miscellaneous the compacted machine, in addition to for being compacted the big of the tires such as mine, dam driving steel wheeled vibratory
Outside type road roller, other types of road roller all has sprinkler system.Water in water tank is sprayed onto steel wheel (glue by sprinkler system
Wheel) on, it can not only play the role of keeping steel wheel (rubber tire) surface cleaning, can also prevent road roller from dripping during the work time
The materials such as blueness, clay, which are pasted on steel wheel (rubber tire), causes compaction quality and construction efficiency to reduce.General road roller watering system
System mainly includes the elements such as sprinkler tank, water spray hose, control switch, water filler, electric water pump, spray head strut, spray head, specifically
The course of work are as follows: after manual closing control switch, electric water pump energization start running, water flow from sprinkler tank bottom be sucked out through
Water filler, electric water pump, spray head strut reach spray head, and in the presence of hydraulic pressure, water flow is sprayed on steel wheel (rubber tire), to it
It is cleaned；After disconnecting control switch, electric water pump power-off stalling, watering stops, and entire watering process belongs to completely passive
Control.
For traditional road roller sprinkler system, when electric water pump operation, the pipeline of entire sprinkler system is opened,
Watering amount in unit time is constant, i.e., the volume of spray head ejection water is identical in section at the same time.And the work of road roller
Make environment and place changes at random, under the conditions of the road surface for rolling different materials and same road surface difference number of rolling
The speed of service is different, therefore the problem is that makes watering excessive when the road roller speed of service is slower, water flow is along steel
Wheel (rubber tire) drops onto road surface, it is possible that water flow destroys the road surfaces phenomenons such as the pitch being compacted while waste water resource；
To sprinkle water when the road roller speed of service is very fast less, steel wheel (rubber tire) is not enough to be wet cleaning, with the continuation rolled,
The materials such as pitch, clay can be attached to steel wheel (rubber tire) surface, influence pavement compaction quality and working efficiency.
Further, since the installation site of sprinkler tank will be typically higher than electric water pump, the control switch of traditional sprinkler system is disconnected
After opening, due to the effect of gravity, water flow can then pass through water pump vane gap full of the water spray hose before electric water pump
Spray head is eventually arrived at, halfway weeping of cutting off the water occurs.Weeping cannot not only play cleaning steel wheel (rubber tire) surface
Effect, waste water resource, can also drop onto ground shock to the road surface being compacted, cause pit phenomenon.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts, providing a kind of watering amount can transport with road roller
The semi-automatic sprinkling control system of scanning frequency degree and real-time change.
The utility model is achieved through the following technical solutions:
A kind of semi-automatic sprinkling control system of new road roller, including sprinkler tank, water filler, electric water pump, water flow pass
Sensor, flow control valve, wheel speed sensors, microprocessor ECU, electric control water valve, battery, control switch, electric wire, watering are soft
Pipe, spray head strut, spray head, pipeline；It is the sprinkler tank, water filler, electric water pump, water flow sensing unit, flow control valve, automatically controlled
Water valve passes sequentially through pipeline and is connected, and the spray head strut is connected on electric control water valve by the water spray hose, the spray head peace
On spray head strut；The battery is electrically connected with the electric water pump, electric control water valve respectively after passing through control switch；It is described
Water flow sensing unit connects the microprocessor ECU for the watering amount in the real-time detection unit time, output end；The wheel speed
Sensor is used to detect the revolving speed of steel wheel or rubber tire, and output end is connected with the microprocessor ECU；The microprocessor ECU
Two kinds of signals for detecting the water flow sensing unit and wheel speed sensors carry out calculating integration matching, issue control letter
Number, output end is connected with the flow control valve, to control the valve opening of flow control valve.
Further improvement project is, when the speed that the wheel speed sensors detect reaches maximum, flow control valve
Valve wide open；When the speed that the wheel speed sensors detect is reduced to certain value, valve is closed to minimum；When road roller is sprinkled water
Speed of service size and flow control valve aperture correspond.
The beneficial effects of the utility model are:
(1) by carrying out semi- active control to sprinkler system, watering amount changes with the variation of the road roller speed of service, makes
It must sprinkle water with controllability, not only meet the demand on cleaning steel wheel surface, but also eliminate the excess occurred when speed is slower and spill
Water phenomenon, avoid because watering amount it is big caused by pavement destruction phenomenon, protect road surface to save water resource again.
(2) as the quickening of speed, watering amount increase, ensure that can be sufficiently humidified so as to steel wheel (rubber tire) surface, and pitch glues
The materials such as soil will not be bonded on steel wheel (rubber tire), improve pavement compaction quality and construction efficiency.
(3) electric control water valve is mounted on the end of sprinkler system, spring return function after power-off, and valve is closed, and water flow is truncated, stops
Weeping disappearance is spilt, the pit that road surface occurs by water impact is eliminated, has saved water resource.
