More and more widely increasingly high along with the cartridge valve technical application with the level of integration of hydraulic system; The flow of the electro-hydraulic reversing valve in the conventional hydraulic and volume more and more can't adapt to the construction demand of main equipment; Therefore need to adopt the cartridge valve control technique to design and to satisfy the integrated cartridge valve formula concrete pump hydraulic system of height that transmission and concrete transmission requires, to satisfy the concrete pumping technique requirement of big flow, high pressure.
The model utility content
The technical problem that the utility model solved is to provide a kind of transmission and concrete transmission pump hydraulic system that full hydraulic control two-way plug-in valve system is housed, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
The transmission and concrete transmission pump hydraulic system of full hydraulic control two-way plug-in valve system is housed, comprises oil pump, oil cylinder, main valve piece and oil pipe, oil pump has main oil pump, for the motion of oil cylinder provides hydraulic oil; Oil cylinder comprises master cylinder and switching-over oil cylinder, and master cylinder is used to control the pumping system liquid and presses flowing of oil, and the switching-over oil cylinder is used to control the switching-over of distributing valve; The main valve piece is used for whole hydraulic system is controlled and regulated; The main valve piece is provided with solenoid directional control valve, cartridge valve and branch oil distributing hole; Solenoid directional control valve connects cartridge valve, realizes the switching to the positive and negative pump of hydraulic system and high low pressure through the control cartridge valve, and realization is to the control of the flow direction of hydraulic oil in the motion of master cylinder and the hydraulic system; Divide oil distributing hole to connect cartridge valve and the external oil pipe of main valve piece; Said oil pipe is connected with main valve piece, oil pump, oil cylinder, is communicated with whole hydraulic system, realizes the regulating and controlling function of main valve piece.
The said transmission and concrete transmission pump hydraulic system that full hydraulic control two-way plug-in valve system is housed adopts full hydraulic control technology, at the front end of master cylinder sentinel valve is installed, and utilizes in the hydraulic system flowing of hydraulic oil to realize the automatic reverse of master cylinder.
The said transmission and concrete transmission pump hydraulic system that full hydraulic control two-way plug-in valve system is housed also comprises gear pump, is used for controlling the work of stirring system, adopts the parallelly connected oil circuit of double pump single loop with main oil pump, and switching-over pressure is big, engine power utilization ratio height, energy saving.

Description of drawings
Fig. 1 is the hydraulic system principle figure of the utility model preferred embodiment.
Among the figure: main oil pump 1, master cylinder 2, switching-over oil cylinder 3.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the transmission and concrete transmission pump hydraulic system of the full hydraulic control two-way plug-in valve of being equipped with of Fig. 1 system, comprise main oil pump 1, master cylinder 2 and switching-over oil cylinder 3, main valve piece, connect through oil pipe, be communicated with and be whole hydraulic system.
The running principle of the utility model is for master cylinder, two of left oil cylinder and right oil cylinders are arranged.The piston of oil cylinder is divided into two cavitys with cylinder barrel; Rodless cavity is equipped with sentinel valve; One end of sentinel valve is connected the top of rodless cavity, and the other end connects slightly past position intermediate, all has been full of hydraulic oil in the cavity; The rodless cavity of left side oil cylinder connects the rodless cavity of right oil cylinder through oil pipe, and the rod chamber of right oil cylinder also is to be connected through oil pipe with the rod chamber of left oil cylinder.When oil cylinder moved under the drive of oil pump, the piston of oil cylinder will move forward and backward.When the piston forward of left oil cylinder moved, hydraulic oil rodless cavity from left oil cylinder under the high pressure effect flowed out, and flows into the rodless cavity of right oil cylinder through oil pipe; And the piston that promotes right oil cylinder moves backward, and the hydraulic oil in the right cylinder rod chamber also flow in the rod chamber of left oil cylinder through oil pipe, the piston forward of left oil cylinder move to a certain degree in; The sentinel valve of rodless cavity activates; The preceding rod chamber of left side oil cylinder is communicated with, and under the switching-over control of main valve piece, the piston forward of right oil cylinder moves; Make the process antikinesis of front, thereby accomplish the reciprocation cycle operation.
Being used to switch the solenoid directional control valve of high low pressure in the utility model replaceable is half manual automanual high low pressure switching valve piece.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
