Embodiment 2
The control system of supporting leg control mechanism described in embodiment 1 is present embodiments provided, as shown in figure 5, including ball valve
16, logic control valve 15 controls operation valve 14 with supporting leg, and wherein ball valve 16 is connect with the vertical oil cylinder supporting leg；Logic control valve
15 logic control horizontal support legs and vertical oil cylinder supporting leg it is flexible：1）When horizontal support legs extend to precalculated position rear steering control vertically
Oil cylinder supporting leg stretches out, and 2）It is shunk when vertical oil cylinder supporting leg is retracted to precalculated position rear steering controlled level supporting leg；Supporting leg control behaviour
Make valve 14 to stretch out and vertical oil cylinder supporting leg contraction by 15 controlled level supporting leg of logic control valve.
Specific control process is as follows：
（1）When supporting leg control mechanism stretches out, operation supporting leg controls operation valve 14, and oil circuit is first right by logic control valve 15
The big chamber fuel feeding of double head oil cylinder pushes cylinder rod protruding with respect to double head oil cylinder, and cylinder rod pushes connecting rod, connecting rod to push horizontal support legs edge
The fixed supporting leg case of subframe is protruding, realizes that horizontal support legs stretch out, after horizontal support legs reach precalculated position, feedback signal
Logic control valve 15 is set to commutate, oil circuit shifts to vertical oil cylinder supporting leg, realizes the stretching of vertical oil cylinder supporting leg；
（2）When supporting leg control mechanism is withdrawn, first operates supporting leg and control operation valve 14, oil circuit is first to the small chamber of vertical oil cylinder supporting leg
Fuel feeding, after vertical oil cylinder supporting leg receives precalculated position, feedback signal makes logic control valve 15 commutate, and oil circuit is shifted to double head oil cylinder
Small chamber fuel feeding pushes cylinder rod to retract inwards with respect to double head oil cylinder, and cylinder rod pulls connecting rod, connecting rod to pull horizontal support legs along subframe
Fixed supporting leg case is retracted inwards, and implementation mechanism is withdrawn.
The supporting leg control mechanism and leg control system of above example, at it in use, with supporting leg stretching and supporting leg
Two kinds of working conditions of retraction, when needing supporting leg to stretch out, monolever operates supporting leg and controls operation valve 14, and oil circuit passes through logic control
Valve 15 pushes cylinder rod protruding with respect to double head oil cylinder 2 first to 2 big chamber fuel feeding of double head oil cylinder, right side cylinder rod promotion connecting rod I 4,
Connecting rod II 5, connecting rod I 4, connecting rod II 5 push horizontal support legs I 3, horizontal support legs II 6 protruding, left side cylinder rod promotion connecting rod III 8,
Connecting rod IV 9, connecting rod III 8, connecting rod IV 9 push horizontal support legs III 7, horizontal support legs IV 10 protruding.Because left and right side cylinder rod is stretched out
With synchronism, so supporting leg 3,6,7,10, which stretches out, has synchronism.After level reaches position, horizontal support legs reach a detection switch
11 must be electric, and providing signal makes logic control valve 15 commutate, and oil circuit shifts to vertical oil cylinder supporting leg 12, realizes and first stretch water when stretching supporting leg
Flat leg stretches the automatic switchover of vertical leg again.
When needing supporting leg to bounce back, monolever operates supporting leg and controls operation valve 14, and oil circuit is first small to vertical oil cylinder supporting leg 12
Chamber fuel feeding, after vertical oil cylinder supporting leg 12 receives position, triggering vertical leg is reduced to a detection switch 13, and logic control valve 15 is made to change
To oil circuit is shifted to 2 small chamber fuel feeding of double head oil cylinder, and cylinder rod is pushed to retract inwards with respect to double head oil cylinder 2, and right side cylinder rod pulls connecting rod
I 4, connecting rod II 5, connecting rod I 4, connecting rod II 5 pull horizontal support legs I 3, horizontal support legs II 6 to retract inwards, and left side cylinder rod pulls connecting rod
III 8, connecting rod IV 9, connecting rod III 8, connecting rod IV 9 pull horizontal support legs III 7, horizontal support legs IV 10 to retract inwards.Realize contracting supporting leg
When first contracting vertical leg contracting horizontal leg again automatic switchover.Retracting because of left and right side cylinder rod has synchronism, so supporting leg 3,6,7,10
Retracting has synchronism.
Further, the big lumen road of each vertical oil cylinder supporting leg 12 increases ball valve 16, realizes each vertical oil cylinder supporting leg
Individually adjust.
To sum up, the supporting leg control mechanism and leg control system of the utility model passes through single double head oil cylinder, four levels
The supporting leg retractable mechanism that supporting leg, four connecting rods form passes through one group of supporting leg and controls the compositions such as operation valve, logic control valve, ball valve
Leg control system, have parts few, substantially reduce cost, and improve the effect of efficiency of assembling and working efficiency, because
It stretches out or the good feature of retraction synchronism, to avoid individual supporting legs from stretching reductions supporting leg span reduction whole vehicle stability not in place,
The sequence requirements for automatic control to landing leg stretching is realized, is met and is first stretched horizontal leg when stretching supporting leg and stretch vertical leg, contracting supporting leg again
When first contracting vertical leg contracting horizontal leg again safety requirements, while using monolever, reduce operation and require.
Above example and application examples are the explanations with embodiment to the utility model, rather than to the utility model
Limitation, person skilled in the relevant technique can also do in the case where not departing from the spirit and scope of the utility model
Go out various transformation and variation obtains corresponding equivalent technical solution, therefore all equivalent technical solutions should be included into
The scope of patent protection of the utility model.
