Description
Technical field
The utility model relates to a kind of hydraulic control circuit, specifically is a kind of anti-twin-tub control oil hydraulic circuit that waves and change oil automatically of mortar vehicle hopper that is used for.
Technical background
At present, domestic mortar vehicle hopper prevents that waving the loop generally adopts the locked cylinder circuit of one-way valve, and the action of control oil hydraulic cylinder realizes rocking-prevention function, there is no the function of regularly changing oil automatically, can not carry out exhaust.After main frame used in the open air for a long time, it is big that turbidity test decline, emulsification, air content appear in the hydraulic oil of oil cylinder inside, influences the stationarity of hopper work.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of hopper the anti-twin-tub control oil hydraulic circuit that waves and change oil automatically, is used for the mortar vehicle hopper and prevents waving, changing oil automatically.
The utility model is realized with following technological scheme: the anti-twin-tub control oil hydraulic circuit that waves and change oil automatically of a kind of hopper comprises oil hydraulic pump, two four-way electromagnetic reversing valves, relief valve, 2/2-way Solenoid ball valve, Pilot operated check valve, pressure measurement exhaust joint and two oil hydraulic cylinders; Its annexation is: oil hydraulic pump links by the oil inlet P of pipeline and two four-way electromagnetic reversing valves, the A mouth of two four-way electromagnetic reversing valves links by the oil inlet P of pipeline and 2/2-way Solenoid ball valve, the B mouth of two four-way electromagnetic reversing valves links by the filler opening A of pipeline and Pilot operated check valve 5, the T mouth of two four-way electromagnetic reversing valves flows back to fuel tank by pipeline, the oil outlet T of 2/2-way Solenoid ball valve 4 links by the hydraulic control hydraulic fluid port X of pipeline and Pilot operated check valve 5, and the oil outlet B of Pilot operated check valve 5 links with the rod chamber and the rodless cavity of oil hydraulic cylinder 7 respectively by pipeline.The high-voltage oil liquid that oil hydraulic pump provides enters Pilot operated check valve from a working position of two four-way electromagnetic reversing valves, is full of two chambeies of two oil hydraulic cylinders then.Two four-way electromagnetic reversing valves commutate to another working position, and hydraulic oil enters 2/2-way Solenoid ball valve loop by two four-way electromagnetic reversing valves and ended by the 2/2-way Solenoid ball valve.Hydraulic control mouth zero-pressure, the two-chamber of locked two oil hydraulic cylinders of Pilot operated check valve, two oil hydraulic cylinder cooperating structure spares carry out mutual-inverse type work, and fluid complements one another, and guarantees finished product hopper easy motion, prevents that pitch from scattering in the discharging process.When main frame is long-time use after, be present between Pilot operated check valve and the oil hydraulic cylinder fluid and turbidity test occur and descend and emulsion.Control 2/2-way Solenoid ball valve is changed to another working position, Pilot operated check valve is opened, the hydraulic oil that used of locking between oil hydraulic cylinder and Pilot operated check valve is got back to hydraulic oil container, again control two four-way electromagnetic reversing valves again to the initialization position, new hydraulic oil reenters oil hydraulic cylinder, realize the replacing automatically regularly of hydraulic oil in the oil hydraulic cylinder, filter.And can carry out exhaust by the pressure measurement exhaust joint, guarantee the oil cylinder traveling comfort.
The beneficial effects of the utility model are: the control principle novelty, the motion of finished product hopper steadily, stable and reliable for performance, miscellaneous function is comprehensive, can realize regular automatic exchange fluid, effectively preventing the decline of cleanliness of hydraulic oil degree and the problem that emulsification brings, can significantly reduce rate of fault, make main frame be more suitable for the field construction operation.
Description of drawings
