Technical field

The present invention relates to a kind of hydraulic system, specifically a kind of one station hydraulic system of multimachine.

Background technique

It is well known that " one station of multimachine " hydraulic system of complete set by a set of pressure control loop, cover direction controlling Circuit, more set speed control loops and more set safety locking circuits composition, conventional " one station of multimachine " hydraulic system share one Pressure control loop is covered, cocircuit all respectively corresponds to a set of.Under normal circumstances, this configuration can satisfy requirement, but It is the pressure control loop damage once shared, it will entire hydraulic system is caused to can not work normally.

As shown in Figure 1, Fig. 2 is that conventional double lifting point is " more for conventional double lifting point " one station of multimachine " hydraulic system principle figure One station of machine " hydraulic system pumping plant figure can be seen from the chart, pressure control loop shares a set of in conventional system, pressure Power control loop is once broken, and whole system, which all can not afford, to be come.

As shown in figure 3, conventional scheme is again the system of a set of striking resemblances of polygamy, it is the problem that can solve in this way, but It is this scheme expense space and cost height, so this is not a good solution；It is another again there are also a kind of scheme Outer standby a set of pressure valve group, if former pressure valve group damage, then standby pressure valve group is changed, this method is both economical, but It is, it is pretty troublesome, it obtains and first original system is closed, removed pressure dump, then former pressure valve group, then change spare valve group, such as There is above accident in the case where very urgent in fruit, it is likely that can be delayed the best opportunity, cause immeasurable loss.

Summary of the invention

The technical problem to be solved by the present invention is hydraulic system can be normal when how to realize pressure control loop damage Work.

In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme:

The present invention is a kind of one station hydraulic system of multimachine, including circuit pressure adjusts control module；Circuit pressure adjusts control Molding block includes the first control loop being arranged in parallel on major loop, the second control loop；First control loop includes series connection First pressure control valve group, the first ball valve are set；Second control loop includes being arranged in series second pressure control valve group, the second ball Valve；

In pressure control loop, then a set of pressure control loop in parallel, centre is switched by ball valve.In case of meaning Outside, it is only necessary to switch corresponding ball valve, so that it may realize the switching of pressure valve group.Ensure that entire hydraulic system can operate normally.

When normal, the first ball valve is opened, and first pressure control valve group electromagnet obtains electric construction pressure, and the second ball valve is closed；Occur When failure, the first ball valve is closed, and the second ball valve is opened, and second pressure control valve group electromagnet obtains electric construction pressure.

In order to illustrate other modules of the invention, the invention also includes there is multiple electric oil pumps being arranged in parallel, electricity Dynamic oil pump is suitable for giving system fuel feeding；Confluence module, confluence module are connected with electric oil pump, and confluence module is suitable for converging oil Stream, and supply major loop；Pressure flow, temperature interface control module, pressure flow, temperature interface control module and circuit pressure Control module series connection is adjusted, the flow and temperature that major loop oils are adapted to detect for.

Filtering module, filtering module are connected with pressure flow, temperature interface control module, for filtering the oil of reflux；Control Liquefaction cylinder motion module, control cylinder movement module are connected with filtering module, and the movement of oil cylinder is controlled by electromagnetic switch.

Beneficial effects of the present invention: the present invention is a kind of one station hydraulic system of multimachine, is returned by being arranged in parallel the first control Road, spare second control loop, when the damage of the first control loop, the second control loop is used, and enables entire hydraulic system It is enough to operate normally.
