Above-mentioned valve group 1 can be widely used in various hydraulic control circuits; Be particularly useful for having the hydraulic control circuit of a plurality of actuators; Thereby only need dispose the action (the relevant controlling principle is with explaining in more detail in the hydraulic control circuit hereinafter) that a proportional reversing valve just can be controlled a plurality of actuators relatively independently, thereby save cost.
Four-way change-over valve 11 can adopt various suitable structural types, for example can be two-position four way change valve or three position four-way directional control valve.If four-way change-over valve 11 is a two-position four way change valve; Then therein in working position; The pressure hydraulic fluid port 11P of this four-way change-over valve 11, return opening 11T and the first actuator port 11A, the parallel conducting of the second actuator port 11B (position, a left side as shown in Figure 1; Be the pressure hydraulic fluid port 11P and the first actuator port 11A conducting; The return opening 11T and the second actuator port 11B conducting) or cross-conduction (not shown, i.e. the pressure hydraulic fluid port 11P and the second actuator port 11B conducting, the return opening 11T and the first actuator port 11A conducting); In another working position, the connected state of the pressure hydraulic fluid port 11P of this four-way change-over valve 11, return opening 11T and the first actuator port 11A, the second actuator port 11B can be identical with the connected state of the proportional reversing valve that will be connected (for example hereinafter proportional reversing valve 3) when being positioned at meta.If four-way change-over valve 11 is a three position four-way directional control valve, then except two working positions as shown in Figure 1, the working position of a cross-conduction can also be set.
Said four-way change-over valve 11 and/or said bi-bit bi-pass selector valve 12 are solenoid directional control valve, also can be pilot operated directional control valve, hand-operated direction valve etc.
On the other hand; As shown in Figure 2; According to one embodiment of the present invention a kind of hydraulic control circuit is provided; This hydraulic control circuit comprises proportional reversing valve 3 and a plurality of 39a of actuator, 21, and wherein, this hydraulic control circuit also comprises respectively and said a plurality of 39a of actuator, 21 corresponding a plurality of valve groups 1 as indicated above; Each said 39a of actuator, two working oil path of 21 are communicated with the first actuator port 1A and the second actuator port 1B of corresponding said valve group 1 respectively, and the pressure hydraulic fluid port 1P of said valve group 1 and return opening 1T are communicated with the first actuator port 3A and the second actuator port 3B of said proportional reversing valve 3 respectively.
Preferably, as shown in Figure 2, the hydraulic fluid port connected state when the hydraulic fluid port connected state the when four-way change-over valve 11 of said valve group 1 is in one of them working position is in meta with said proportional reversing valve 3 is identical.As indicated above, another working position then can be logical state of parallel conductive or cross-conduction state.
Proportional reversing valve 3 can be selected various meta functions for use according to actual conditions; Preferably, as shown in Figure 2, this proportional reversing valve 3 is the selector valve of Y type meta function; That is to say; When said proportional reversing valve 3 was in meta, the first actuator port 3A of said proportional reversing valve 3 and the second actuator port 3B were communicated with the return opening 3T of said proportional reversing valve 3, and the pressure hydraulic fluid port 3P of said proportional reversing valve 3 ends.The proportional reversing valve 3 of Y type meta function can be formed the locking loop with equilibrium valve 4 as mentioned below or bidirectional hydraulic lock 7 etc.; When proportional reversing valve 3 switches to meta; The pilot pressure of equilibrium valve or bidirectional hydraulic lock 7 can discharge immediately; One-way valve is closed immediately, and actuator is stop motion immediately.In addition, when the proportional reversing valve 3 of Y type meta function was in meta, the pressure hydraulic fluid port ended, and can prevent the action phase mutual interference of a plurality of actuators.
Preferably, also be connected with equilibrium valve 4 on each said 39a of actuator, 21 two working oil path.Thereby can improve the stationarity of the 39a of actuator, 21 actions.Equilibrium valve 4 can adopt the various suitable equilibrium valves or the form of balanced loop, for example balanced loop of the balanced loop of one way sequence valve and Pilot operated check valve etc.About the concrete structure and the mounting type of equilibrium valve 4 is well known in the art, repeat no more at this.

In mode of execution as shown in Figure 2, have two 39a of actuator, 21 and two corresponding valve groups 1 in this hydraulic control circuit, certainly also correspondingly increase the number of valve group 1 according to the number of practical situations increase actuator.
Carry out briefly bright in the face of the working principle of hydraulic control circuit as shown in Figure 2 down.Hydraulic control circuit with the 39a of actuator is an example.If the electromagnet Y4 of the four-way change-over valve 11 of valve group 1 and the electromagnet Y3 of bi-bit bi-pass selector valve 12 must not; Then no matter proportional reversing valve 3 is in position, a left side or right position; Two working oil path of the 39a of actuator all with proportional reversing valve 3 not conductings, it is motionless that the 39a of actuator keeps.If it is electric that the electromagnet Y4 of the four-way change-over valve 11 of valve group 1 and the electromagnet Y3 of bi-bit bi-pass selector valve 12 get, then valve group 1 is equivalent to two paths, and the 39a of actuator moves according to proportional reversing valve 3 residing positions; If proportional reversing valve 3 is positioned at position, a left side (Y1 gets); Then the piston rod of the 39a of actuator (oil cylinder) stretches out; If proportional reversing valve 3 is positioned at right position (Y2 gets); The then piston rod of the 39a of actuator (oil cylinder) withdrawal, if proportional reversing valve 3 is positioned at meta (Y1, Y2 all must not), then the maintenance of the piston rod of the 39a of actuator (oil cylinder) is motionless.In addition; When needing the piston rod of the 39a of actuator to stretch out; Proportional reversing valve 3 is positioned at position, a left side (Y1 gets); Can make this moment the electromagnet Y4 of the four-way change-over valve 11 of valve group 1 get the electromagnet Y3 of electric and bi-bit bi-pass selector valve 12 can electricity, thereby bi-bit bi-pass selector valve 12 is in right position, and its unidirectional conducting allows oil return.The working principle of the hydraulic control circuit of actuator 21 is also similar with the 39a of actuator, the electromagnet Y5 of four-way change-over valve 11 that can be through control valve group 1 and the electromagnet Y6 of bi-bit bi-pass selector valve 12 whether electricly come 3 pairs of actuators of control ratio selector valve 21 whether to work.Thereby, only need dispose a proportional reversing valve 3 and just can control a plurality of 39a of actuator, 21 action relatively independently, saved the cost of hydraulic control circuit.
Also on the other hand; Extremely shown in Figure 5 like Fig. 3; According to one embodiment of the present invention a kind of auxiliary device that is used for the installation or removal component is provided; The said auxiliary device that is used for the installation or removal component comprises on carrier bar 10 and this carrier bar 10 of installation and is used to support the supporting leg 30 of this carrier bar 10; Said supporting leg 30 can rotate around the orthogonal first axle X and the second axis Z with respect to said carrier bar 10; Wherein, the said auxiliary device that is used for the installation or removal component comprises also that according to hydraulic control circuit as indicated above said a plurality of actuators of this hydraulic control circuit comprise first 39a of actuator and second actuator 21; Said first 39a of actuator is used to drive said supporting leg 30 and rotates around said first axle X with respect to said carrier bar 10, and said second actuator 21 is used to drive said supporting leg 30 and rotates around the said second axis Z with respect to said carrier bar 10.
