Abstract
The utility model relates to a stable start and stop control system of a double-steel-wheel road roller, comprising an electronic control operating handle, a controller and an electronic control proportion hydraulic pump, wherein the electronic control operating handle, the controller and the electronic control proportion hydraulic pump are sequentially connected, the electronic control operating handle outputs an electric signal to the controller, the controller outputs a PWM (Pulse-Width Modulation) signal to control the electronic control proportion hydraulic pump, so as to control the movement speed of a servo cylinder piston of the electronic control proportion hydraulic pump, thereby controlling the start and stop of the double-steel-wheel road roller and achieving the purpose of starting and stopping stably. The stable start and stop control system of the double-steel-wheel road roller has the beneficial effects that: the control system can effectively solve the crowd-stacking problem in the compaction process, the compaction quality of a road surface is improved, the impact pressure of a hydraulic system is reduced, the service life of a hydraulic element is prolonged and the driving comfort is increased.
Description
Technical field
The utility model relates to a kind of dual-steel wheel road roller and steadily works the control system of stopping, and belongs to engineering machinery manipulation technology field.
Background technology
Present homemade double-steel wheeled vibratory roller, the inertia load in its starting and the process of stopping impacts bigger, brings great damage on the one hand the hydraulic pressure element, also can cause the road surface heap phenomenon to occur gathering around on the other hand, has a strong impact on consolidation effect.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of dual-steel wheel road roller steadily to work the control system of stopping, the inertia load that solves in the starting of double-steel wheeled vibratory roller and the process of stopping impacts bigger problem.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
A kind of dual-steel wheel road roller steadily works the control system of stopping; It comprises electrically controlled manipulation handle 1, controller 2, automatically controlled ratio hydraulic pump 3, and electrically controlled manipulation handle 1, controller 2, automatically controlled ratio hydraulic pump 3 connect successively, and the electrically controlled manipulation handle 1 output signal of telecommunication is given controller 2; Controller 2 output pwm signals are controlled automatically controlled ratio hydraulic pump 3; Control the movement velocity of automatically controlled ratio hydraulic pump 3 servoBcylinder pistons, and then rising of control dual-steel wheel road roller stop, to reach and steadily work the purpose of stopping.
The operating principle of the utility model: in the starting stage, it is electric through controller the electric-controlled hydraulic pump to be got, and control electric-controlled hydraulic pump is exported discharge capacity within a certain period of time and progressively risen to the operate as normal discharge capacity by less discharge capacity; In the stage of stopping, progressively be decreased to less discharge capacity by the operate as normal discharge capacity within a certain period of time through controller control electric-controlled hydraulic pump, control electric-controlled hydraulic pump dead electricity again.
The beneficial effect of the utility model is: this control system can effectively solve the heap problem of gathering around in the compacting process, improves the pavement compaction quality, reduces the hydraulic system surge, prolongs Hydraulic Elements application life, increases driver comfort.
Description of drawings
Fig. 1 is the structure principle chart of the utility model.
Wherein: 1-electrically controlled manipulation handle, 2-controller, the automatically controlled ratio hydraulic pump of 3-.
The specific embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1; The described a kind of dual-steel wheel road roller of this specific embodiment steadily works the control system of stopping; It comprises electrically controlled manipulation handle 1, controller 2, automatically controlled ratio hydraulic pump 3, and electrically controlled manipulation handle 1, controller 2, automatically controlled ratio hydraulic pump 3 connect successively, and the electrically controlled manipulation handle 1 output signal of telecommunication is given controller 2; Controller 2 output pwm signals are controlled automatically controlled ratio hydraulic pump 3; Control the movement velocity of automatically controlled ratio hydraulic pump 3 servoBcylinder pistons, and then rising of control dual-steel wheel road roller stop, to reach and steadily work the purpose of stopping.
The operating principle of this specific embodiment: in the starting stage, it is electric through controller the electric-controlled hydraulic pump to be got, and control electric-controlled hydraulic pump is exported discharge capacity within a certain period of time and progressively risen to the operate as normal discharge capacity by less discharge capacity; In the stage of stopping, progressively be decreased to less discharge capacity by the operate as normal discharge capacity within a certain period of time through controller control electric-controlled hydraulic pump, control electric-controlled hydraulic pump dead electricity again.
The beneficial effect of this specific embodiment is: this control system can effectively solve the heap problem of gathering around in the compacting process, improves the pavement compaction quality, reduces the hydraulic system surge, prolongs Hydraulic Elements application life, increases driver comfort.
