Abstract
A quick-replacing control device for priority-shunt fittings comprises a hydraulic pump outlet, and is characterized in that a second oil tube is inserted into a quick-replacing control priority-shunt fitting valve, the quick-replacing control priority-shunt fitting valve is communicated with a chamber with a rod of a hydraulic cylinder through a third oil tube, communicated with a chamber without the rod of the hydraulic cylinder through a fourth oil tube, and communicated with a hydraulic oil tank through a first oil tube; fittings are controlled to be separated from a quick-replacing mechanism by controlling the electromagnetic valve to be powered on, and are controlled to be locked with the quick-replacing mechanism by controlling the magnetic exchange valve to be powered off. Various fittings assorted in one device and replaced manually by disassembling and assembling connecting pins are both time-consuming and labor-consuming. By the aid of the quick-replacing control device for the priority-shunt fittings, the various fittings can be quickly and easily replaced among one another by independent steering control of a driver in a driving cab.
Description
Technical field
The utility model relates to construction machinery hydraulic system, especially a kind of preferential shunting accessory quick change control device.
Background technology
On construction machinery product uses, especially on crawler-mounted excavator, crawler type material grasping (steel) machine, many times according to the applying working condition difference, need to change different supporting accessories, adopt manually of traditional mode changed by dismounting connection pivot pin more, and this substitute mode is not only time-consuming but also require great effort.If accessory quick-changing mechanism and a kind of preferential shunting accessory quick change control device thereof have been installed, the driver just can independently control the quick replacing that just can easily realize between the various accessories by handling in the driver's cabin like this.
Summary of the invention
Do not have preferentially to shunt the quick control valve of accessory and corresponding control hydraulic means on the construction machinery hydraulic system in order to overcome to have now, the utility model provides a kind of and is controlling the quick-replaceable hydraulic control device that just can easily realize various accessories between by manual control for the driver is independent in the driver's cabin.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of preferential shunting accessory quick change control device, be that hydraulic pump passes through second oil pipe and is communicated with preferential shunting accessory quick change control valve oil-in, preferential shunting accessory quick change control valve is communicated with hydraulic oil container by first oil pipe respectively, be communicated with the rod chamber of hydraulic jack by the 3rd oil pipe, be communicated with the rodless cavity of hydraulic jack by the 4th oil pipe, get the electric quick disengagement of controlling accessory and quick-changing mechanism by the solenoid operated directional valve of controlling on the preferential shunting accessory quick change control valve, control the pinning of accessory and quick-changing mechanism by control solenoid operated directional valve dead electricity.
Preferential shunting accessory quick change control valve can retract the rod chamber of the preferential flow-dividing control hydraulic jack of hydraulic pump rate of discharge and stretch out to reach the quick change replacing of control accessory, and its another one actuator port can utilize residual flow to go to control other loads.
Further, described hydraulic pump is constant displacement pump, and hydraulic jack is double acting single-rod piston cylinder, and described preferential shunting accessory quick change control valve is a kind of cartridge valve integrated valve block of realizing compound control.
Further, described preferential shunting accessory quick change control valve is made up of valve body, hydraulic control one-way valve, accumulator, solenoid operated directional valve, one way valve 1, choke valve 1, one way valve 2, choke valve 2, reducing valve, overflow valve, expansion loop and one way valve 3, has realized the preferential flow-dividing control effect of single channel flow.
Useful result of the present utility model is to provide and can control the quick-replaceable a kind of control device that just can easily realize between the various accessories by handling in the driver's cabin for the driver is independent.
