Abstract
The utility model relates to a nonrigid-structure hydraulic synchronization control system which comprises a three-position four-way valve, a first oil cylinder and a second oil cylinder, wherein the first oil cylinder and the second oil cylinder are connected with the three-position four-way valve after being connected in series, a small cavity of the first oil cylinder is connected with a large cavity of the second oil cylinder, and the cross sectional area S1 of a cavity body of the small cavity of the first oil cylinder and the cross sectional area S2 of a cavity body of the second oil cylinder are the same. The nonrigid-structure hydraulic synchronization control system controls the two oil cylinders connected in series through the three-position four-way valve, and the volumes of the large cavity and the small cavity are the same, so that the operating speed of a piston rod is synchronized. The nonrigid-structure hydraulic synchronization control system achieves the hydraulic synchronization control of two nonrigid light loading members in a simplest and most convenient way, so that the system is safer and more reliable.
Description
Technical field
The utility model relates to the hydraulic synchronous control system of a kind of hydraulic control system, particularly a kind of non-rigid structure.
Background technique
Engineering mechanical device often can adopt non-rigid structure in operation process, and for example the excrement that pushes away for the cleaning of pasture excrement of animals shovels, and is respectively provided with respectively one can synchronously opens or closed guide plate in shovel body both sides.But can be because the unbalanced load that causes left and right guide plate to bear of the material of left and right carrying to be different when practical operation, common oil cylinder is connected in parallel each other, because the load difference of bearing can cause two oil cylinders asynchronous.
Two traditional non-rigid underloading member hydraulic synchronous control systems are by two Proportional valves or servovalve+displacement transducer or angle transducer+controller, to control oil cylinder stroke to realize, and hydraulic system is complicated, and cost is high.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide and a kind ofly just can realizes the hydraulic synchronous control system of the synchronous non-rigid structure of oil cylinder stroke by common valve.
Technological scheme: a kind of hydraulic synchronous control system of non-rigid structure, comprise three-position four-way valve, the first oil cylinder and the second oil cylinder, described the first oil cylinder is connected with three-position four-way valve with after the second oil cylinder series connection; The loculus of described the first oil cylinder is connected with the large chamber of the second oil cylinder, and described the first oil cylinder loculus cavity cross-section area S1 equates with the second large chamber of oil cylinder cavity cross-section area S2.After the protruding LAP of piston rod of the first oil cylinder, fluid in the first oil cylinder loculus enters the large chamber of the second oil cylinder, because the mutual cross-section area of the large loculus cavity of two oil cylinders of series connection equates, therefore also protruding identical stroke of the piston rod of the second oil cylinder; When in like manner piston rod is retracted, stroke also equates.
Beneficial effect: the utility model can be controlled by three position four-way directional control valve the two equal oil cylinders of large loculus volume of series connection, make piston rod motion speed synchronous, the utility model has been realized two non-rigid underloading member hydraulic synchronizations in the mode of simple and fast and has been controlled, and makes system more safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model hydraulic schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, a kind of hydraulic synchronous control system of non-rigid structure, comprises three-position four-way valve 1, the first oil cylinder 2 and the second oil cylinder 3, and described the first oil cylinder 2 is connected with three-position four-way valve 1 with after the second oil cylinder 3 series connection; The loculus of described the first oil cylinder 2 is connected with the large chamber of the second oil cylinder 3, and described the first oil cylinder 2 loculus cavity cross-section area S1 equate with the large chamber cavity cross-section area S2 of the second oil cylinder 3.After the protruding LAP of piston rod of the first oil cylinder 2, fluid in the first oil cylinder 2 loculuses enters the large chamber of the second oil cylinder 3, because the mutual cross-section area of the large loculus cavity of two oil cylinders of series connection equates, therefore also protruding identical stroke of the piston rod of the second oil cylinder 3; When in like manner piston rod is retracted, stroke also equates.
