Electrical control operating handle 11 is connected with electric-control motor 1 and automatically controlled driving pump 2, driving handle, vibrated roller row It walking, operator controls electrical control operating handle 11 and controls electric-control motor 1 toward i.e. increasing stroke, controller 10 is pushed forward and open the throttle, And control automatically controlled driving pump 2 and increase discharge capacity, traveling 4 speed of wheel increase, and then realize the speed Control of traveling wheel 4.
Specifically, under the simple driving cycle of vibrated roller, in the starting stage, operator control electrical control operating handle 11 to Certain position travels vibrated roller, and controller 10 can automatically adjust automatically controlled start according to the position of electrical control operating handle 11 The discharge capacity of the revolving speed of machine 1 and automatically controlled driving pump 2, the discharge capacity of driving pump, nothing can only be adjusted by avoiding control crank in the related technology Method adjust the revolving speed of engine and so that the revolving speed of engine is in maximum (top) speed always and the problem of waste of energy.
In the starting stabilization sub stage, after vibrated roller driving stability, the row of controller 10 (energy-saving controller) monitoring at this time The data for sailing velocity sensor 8 after judging that travel speed is stablized, detect electric-control motor by electric-control motor detection unit 13 1 workload rate, according to the workload rate of electric-control motor 1, the revolving speed for adjusting electric-control motor reaches workload rate To default rate of load condensate (such as rate of load condensate is 80%), initial speed is that the rate of load condensate of electric-control motor 1 is 80% corresponding revolving speed, Since initial speed is less than the maximum (top) speed of electric-control motor 1, so that electric-control motor 1 reaches preset negative with initial speed work Lotus rate, and electric-control motor 1 can greatly reduce the oil consumption of electric-control motor 1 to preset rate of load condensate work, to realize automatically controlled hair The energy-efficient purpose of motivation 1, since the revolving speed that electric-control motor 1 is adjusted to electric-control motor 1 during default rate of load condensate becomes Change so that the travel speed of traveling wheel 4 is changed, by the travel speed change rate of detection traveling wheel 4, based on traveling speed The signal for spending sensor 8, adjusts accordingly the work of the discharge capacity of automatically controlled driving pump 2 or the discharge capacity of driving motors 3 or raising speed case 18 Make state, closed-loop control is formed, so that genemotor 1 and automatically controlled driving pump 2 or driving motors 3 or the common work of raising speed case 18 It can satisfy the power demand of entire vibrated roller, and rapidly to change when 1 revolving speed of electric-control motor and influence to travel When the variation of the speed of wheel 4, pass through the discharge capacity of the automatically controlled driving pump 2 of adjusting or the work of the discharge capacity of driving motors 3 or raising speed case 18 Make state and the rotation speed change of electric-control motor 1 is made to will not influence the speed of traveling wheel 4, and then guarantees that the speed of traveling wheel 4 is steady Surely it will not be mutated, improve the reliability of product, improve the satisfaction that user uses.
