Preferably, as shown in Figure 2, the hydraulic fluid port connected state when hydraulic fluid port connected state when four-way change-over valve 11 of described valve group 1 is in one of them working position and described proportional reversing valve 3 are in meta is identical.As described above, another working position then can lead to state or cross-conduction state for parallel conductive.
Proportional reversing valve 3 can select various Median Function according to actual conditions, preferably, as shown in Figure 2, this proportional reversing valve 3 is the selector valve of Y type Median Function, that is, when described proportional reversing valve 3 is in meta, the first actuator port 3A of described proportional reversing valve 3 is communicated with the return opening 3T of described proportional reversing valve 3 with the second actuator port 3B, the pressure oil port 3P cut-off of described proportional reversing valve 3.The proportional reversing valve 3 of Y type Median Function can form with equilibrium valve 4 as mentioned below or bidirectional hydraulic lock 7 etc. locks loop, when proportional reversing valve 3 is switched to meta, the pilot pressure of equilibrium valve or bidirectional hydraulic lock 7 can discharge immediately, one-way valve is closed immediately, and actuator can stop motion immediately.In addition, when the proportional reversing valve 3 of Y type Median Function is in meta, pressure oil port is ended, and can prevent the action of multiple actuators from mutually disturbing.
Preferably, each described actuator 39a, 21 two working oil path on be also connected with equilibrium valve 4.Thus the stationarity of actuator 39a, 21 actions can be improved.Equilibrium valve 4 can adopt the form of various suitable equilibrium valve or balanced loop, the balanced loop of such as one way sequence valve and the balanced loop etc. of Pilot operated check valve.About the concrete structure of equilibrium valve 4 and mounting type are well known in the art, do not repeat them here.
Described actuator 39a, 21 can be the actuator of various appropriate format, such as, can be oil cylinder, oil hydraulic motor etc.
In the embodiment illustrated in fig. 2, there is in this hydraulic control circuit Liang Ge actuator 39a, 21 and two corresponding valve groups 1, certainly can increase the number of actuator according to practical situations and correspondingly increase the number of valve group 1.
Brief description is carried out to the working principle of hydraulic control circuit as shown in Figure 2 below.For the hydraulic control circuit of actuator 39a.If the electromagnet Y4 of the four-way change-over valve 11 of valve the group 1 and electromagnet Y3 of bi-bit bi-pass selector valve 12 must not be electric, then no matter proportional reversing valve 3 is in left position or right position, two working oil path of actuator 39a all with proportional reversing valve 3 not conducting, actuator 39a keeps motionless.If the electromagnet Y4 of the four-way change-over valve 11 of valve the group 1 and electromagnet Y3 of bi-bit bi-pass selector valve 12 obtains electric, then valve group 1 is equivalent to two paths, and actuator 39a carries out action in the position residing for proportional reversing valve 3; If proportional reversing valve 3 is positioned at left position (Y1 obtains electric), then the piston rod of actuator 39a (oil cylinder) stretches out, if proportional reversing valve 3 is positioned at right position (Y2 obtains electric), then the piston rod of actuator 39a (oil cylinder) is retracted, if proportional reversing valve 3 is positioned at meta (Y1, Y2 must not be electric), then the piston rod of actuator 39a (oil cylinder) keeps motionless.In addition, when needing the piston rod of actuator 39a to stretch out, proportional reversing valve 3 is positioned at left position (Y1 obtains electric), the electromagnet Y4 of the four-way change-over valve 11 of valve group 1 now can be made to obtain the electric and electromagnet Y3 of bi-bit bi-pass selector valve 12 can electricity, thus bi-bit bi-pass selector valve 12 is in right position, its one-way conduction allows oil return.The working principle of the hydraulic control circuit of actuator 21 is also similar with actuator 39a, can by the electromagnet Y6 of the electromagnet Y5 of the four-way change-over valve 11 of control valve group 1 and bi-bit bi-pass selector valve 12 whether electric come control ratio selector valve 3 pairs of actuators 21 whether work.Thus, only need configuration proportional reversing valve 3 just can control relatively independently multiple actuator 39a, 21 action, save the cost of hydraulic control circuit.
Also on the other hand, as shown in Figures 3 to 5, a kind of auxiliary device for installing or removing component is provided according to one embodiment of the present invention, the described auxiliary device for installing or removing component comprises carrier bar 10 and to install on this carrier bar 10 and supporting leg 30 for supporting this carrier bar 10, described supporting leg 30 can rotate around orthogonal first axle X and the second axis Z relative to described carrier bar 10, wherein, the described auxiliary device for installing or removing component also comprises according to hydraulic control circuit as described above, described multiple actuator of this hydraulic control circuit comprises the first actuator 39a and the second actuator 21, described first actuator 39a rotates around described first axle X relative to described carrier bar 10 for driving described supporting leg 30, described second actuator 21 rotates around described second axis Z relative to described carrier bar 10 for driving described supporting leg 30.
Preferably, the described auxiliary device for installing or removing component also comprises stop pin and stop pin actuator 41, this stop pin is for locking the rotation of described supporting leg 30 relative to described carrier bar 10, and described stop pin actuator 41 is for driving described stop pin.Thus when supporting leg 30 turns to desired location, supporting leg 30 can be locked relative to carrier bar 10, to prevent supporting leg 30 accidental movement when installing or removing component and to cause danger.
Stop pin actuator 41 can with above-mentioned actuator 39a, 21 similar, also can be controlled by same proportional reversing valve 3.That is, described auxiliary device also comprises stop pin control valve 5, and this stop pin control valve 5 is connected between described stop pin actuator 41 and described proportional reversing valve 3.This stop pin control valve 5 can adopt the structure identical with above-mentioned valve group 1, also can adopt other control valve to substitute.
Preferably, as shown in Figure 5, described stop pin control valve 5 is two-position four way change valve, first actuator port 5A of described stop pin control valve 5 is communicated with two working oil path of described stop pin actuator 41 respectively with the second actuator port 5B, and the pressure oil port 5P of described stop pin control valve 5 is communicated with the second actuator port 3B with the first actuator port 3A of described proportional reversing valve 3 respectively with return opening 5T.More preferably, when described stop pin control valve 5 is in one of them working position (left position as shown in Figure 5), first actuator port 5A of this stop pin control valve 5 is communicated with return opening 5T with pressure oil port 5P respectively with the second actuator port 5B, when described stop pin control valve 5 is in another working position (right position as shown in Figure 5), the first actuator port 5A of this stop pin control valve 5, the second actuator port 5B, pressure oil port 5P and return opening 5T end.Thus, when stop pin control valve 5 is in left position, the action of stop pin actuator 41 controls by proportional reversing valve 3, when stop pin control valve 5 is in right position, no matter which working position proportional reversing valve 3 is in, two working oil path of stop pin actuator 41 are all ended, and stop pin actuator 41 keeps motionless.Stop pin actuator 41 can be various types of actuator, such as oil cylinder, oil hydraulic motor.Stop pin control valve 5 can adopt the valve of various control mode, such as hydraulic control valve, solenoid valve, hand-operated direction valve etc.
