The working principle of this hydraulic power unit are as follows:
After motor 5 starts, plunger pump 4 is driven to operate by shaft coupling, the inlet port of plunger pump 4 passes through pipeline from fuel tank
Pressure oil is transported to multi-way valve 7 by check valve 6 after pressurizeing in the pump housing by middle sucking hydraulic oil, and check valve 6 can prevent oil stream
Reverse flow.Multi-way valve 7 is made of the identical electric proportionality velocity modulation reversal valve of several functions, is held per a piece of corresponding manipulation one
Units, such as since the left side of multi-way valve 7 first, the cycloid oil motor 9 of the first manipulation driving pedestal rotation, hydraulic oil
Rotary reducer rotation is driven through cycloid oil motor 9, because robot device tower body is fixed on rotary reducer, tower body can
Xiang Shun, turning anticlockwise certain angle reach operating position；The amplitude oil cylinder 11 of second manipulation driving jib system luffing, liquid
If pressure oil enters from the rodless cavity of amplitude oil cylinder 11, flowed back to from the rod chamber of amplitude oil cylinder 11, it can push piston rod to stretch out,
Boom system is set to steeve certain angle, otherwise drop puts certain angle；Third and fourth connection manipulation first and second section boom of driving is respectively rolled over
Folded the first folding arm hydraulic cylinder 14 and the second folding arm hydraulic cylinder 17, if from the first folding arm hydraulic cylinder 14 and the second folding arm hydraulic cylinder 17
Rodless cavity enter, flowed back to from the rod chamber of the first folding arm hydraulic cylinder 14 and the second folding arm hydraulic cylinder 17, then the first folding arm, second
Folding arm, that is, deployable, on the contrary it retracts.5-linked manipulates the manipulator oscillating motor 20 that manipulator is swung, if hydraulic oil is from machinery
The rodless cavity of hand oscillating motor 20 enters, and flows back to from the rod chamber of manipulator oscillating motor 20, i.e. manipulator is to lower swing
One angle, on the contrary it is swung up, it is conveniently adjusted operating position；The grab bucket rotary motor 23 of 6th manipulation manipulator revolution,
Hydraulic oil drives robot device rotation through grab bucket rotary motor 23, is conveniently adjusted operating position；7th manipulation shearing-type is clear
Except the hydraulic shear cylinder of device, if entering from the rodless cavity of hydraulic shear cylinder, flowed back to from the rod chamber of hydraulic shear cylinder, i.e., piston rod is stretched
Out, remove device shearing is driven, convenient for cutting the twister of not easy-clear.Each executive component can be in multi-way valve 7
Corresponding one is changed the manipulation of operative orientation and operating rate.After the completion of executive component work, hydraulic oil passes through back
Oil strainer is to fuel tank.Preferably, can choose plunger pump 4 is load sensitive pump, it is a kind of change that pressure-flow is compensation
Discharge capacity pluger type hydraulic pump only provides the necessary flow of maintenance system work, i.e. hydraulic pump under the operating pressure that load needs
In high-pressure service state but discharge capacity is almost equal to zero, and hydraulic pump will enter wait state at this time, and keep higher work pressure
Power thus is avoided that hydraulic system generates a large amount of heat, plays the role of energy-efficient.When system pressure crosses a up to setting value, liquid
Pressure oil flows back to fuel tank through the overflow valve in multi-way valve 7, plays the role of that excessively high system pressure is avoided to damage executive component.
