Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawings and embodiments, to this
Utility model is described in further detail.
The utility model provides a kind of excavator, as shown in Figure 1, the excavator includes that the electromagnetism unloaded for entrucking is inhaled
Disk 1, hydraulic steel cut 2.The excavator further includes excavator main valve 3, generator 4, excavator main pump 5, hydraulic oil container 6, electric cabinet
7, valve group 8, hydraulic motor 9 are integrated.Wherein, generator powered connects magnechuck, and magnechuck is enable to work；Magnechuck
Hydraulic generator drives valve block to be drivingly connected generator.
Below with reference to Fig. 2 and Fig. 3, the working principle of magnechuck hydraulic generator driving valve block is described in detail.
Wherein, Fig. 2 is the connection structure diagram of the magnechuck hydraulic generator driving valve block of embodiment 1.
The driving valve block includes 2/2-way reversal valve S1, and the oil inlet of 2/2-way reversal valve S1 is dug by piping connection
A mouthfuls of oil outlet for digging owner's pump, the oil outlet of 2/2-way reversal valve S1 pass through the oil inlet B of piping connection excavator main valve
Mouthful.
The driving valve block further includes two-bit triplet reversal valve S2, and the first of the oil inlet of 2/2-way reversal valve S1 passes through
A mouthfuls of the oil outlet of piping connection excavator main pump, second mouthful passes through T mouthfuls of piping connection hydraulic oil container mouth, and third mouth passes through pipeline
Connect CF mouthfuls of oil inlet of driven generator motor.Moreover, between third mouth and CF mouthfuls of oil inlet of driven generator motor
First segment head piece K1 is provided on pipeline.First segment head piece K1 is an adjustable restriction.Moreover, two-bit triplet reversal valve S2
Third mouth presses reservoir port T mouthfuls by overflow valve S3 connection.
Meanwhile the overflow port of 2/2-way reversal valve S1 pass through the second restriction K2 connection two-bit triplet reversal valve S2 the
Three mouthfuls.
The working principle of the driving valve block is described further below.
When two-bit triplet reversal valve S2 no power, stem position in two-bit triplet reversal valve S2 is as shown in Fig. 2, i.e. two
Second mouthful of three-way diverter valve S2 and third mouth are in connection on state.A mouthfuls of oil outlet of hydraulic oil of excavator main pump arrives
It the lower end of 2/2-way reversal valve S1 can be 2/2-way when the hydraulic fluid pressure in the lower end 2/2-way reversal valve S1 is larger
The valve rod of reversal valve S1 shifts left position, i.e. on-position onto, so that hydraulic oil enters B mouthfuls of oil inlet of excavator main valve, thus
Realize each movement of excavator, the flexible of lifting, two arms including large arm, the left and right revolution of platform, the opening and closing of grab bucket, left and right
Walking of crawler belt etc..Moreover, when the pressure in the lower end 2/2-way reversal valve S1 is excessive, can by by extra hydraulic oil according to
It is secondary to return to hydraulic oil container through the second restriction K2, first segment head piece K1, two-bit triplet reversal valve S2 and T mouthfuls of hydraulic oil container mouth.
When two-bit triplet reversal valve S2 is powered, stem position changes in two-bit triplet reversal valve S2, at this time two-bit triplet
The first and third mouth of reversal valve S2 is in connection on state.A mouthfuls of oil outlet of hydraulic oil of excavator main pump is by two
The first of three-way diverter valve S2 by the third mouth of two-bit triplet reversal valve S2 by two-bit triplet reversal valve S2, being gone out, then pass through
Adjustable first segment head piece K1 is crossed, CF mouthfuls of oil inlet of driven generator motor are entered.At this point, passing through adjustable first
Restriction K1 is constant come CF mouthfuls of oil inlet of flow for guaranteeing driven generator motor, that is, the power of fluid power motor is permanent
Determine, that is, the output voltage of generator is constant, guarantees the normal work of magnechuck.
Moreover, B mouthfuls of the oil inlet of excavator main valve are also can have hydraulic oil to pass through.At this point, by needing excavator
The pressure of A mouthfuls of oil outlet of hydraulic oil of main pump is higher than the pressure of the upper end 2/2-way reversal valve S1, can guarantee to dig in this way
Other equipments of pick machine, left and right revolution, the opening and closing of grab bucket, left and right crawler belt of the flexible of lifting, two arms including large arm, platform
The equipments such as walking normal work.
In addition to the embodiment of Fig. 2, Fig. 3 is another embodiment.
In this embodiment, working principle is substantially identical as the working principle of Fig. 2.But in this embodiment, two
The overflow port of two logical reversal valve S1 does not reconnect CF mouthfuls of oil inlet of driven generator motor, but connects T mouthfuls of hydraulic oil container mouth.
At this point, if the pressure of the lower end 2/2-way reversal valve S1 is excessive, it just directly will be more by the overflow port of 2/2-way reversal valve S1
Remaining hydraulic oil is directly returned in hydraulic oil container by T mouthfuls of hydraulic oil container mouth.
It is discussed in detail although the content of the utility model has passed through above preferred embodiment, but it should be appreciated that on
The description stated is not considered as limitations of the present invention.After those skilled in the art have read above content, for
A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the protection scope of the utility model should be by appended
Claim limit.
