Detailed description of the invention
As it is shown in figure 1, a kind of can the hydraulicefficiency elevation structure of two-freedom regulation, including by front side lower branch arm 1, front side
The plane seven-link assembly mechanism that arm 2, entablature 3, rear side upper branch arm 4, rear side lower branch arm 5, pull bar 6, sill 7 are constituted is (such as Fig. 2 institute
Show), a set of integrated hydraulic system 9；Entablature 3 end with front side upper branch arm 2, rear side upper branch arm 4 respectively is connected, on front side
Arm 2, the other end of rear side upper branch arm 3 are connected with front side lower branch arm 1, rear side lower branch arm 5 respectively, lower of front side lower branch arm 1, rear side
The other end of arm 5 is connected with sill 7 respectively, cylinder lever connecting rod 6 between rear side lower branch arm 5 and sill 7；At front side upper branch arm 2
Be separately installed with hydraulic actuator 8 on rear side upper branch arm 4, seven-link assembly mechanism realize under the driving of hydraulic actuator motion,
Hydraulic actuator 8 is driven by hydraulic system 9.When two groups of hydraulic actuator synchronizations of jacking up or contraction, it is achieved hydraulicefficiency elevation structure
Lifting；When handling the independent jacking of hydraulic actuator on upper branch arm or contraction on rear side of upper branch arm or two on front side of in the of two, it is achieved liquid
The regulation of pressure elevating mechanism luffing angle.
Hydraulic system 9 includes fuel tank 901, manual pump 902, oil filter 903, pile-up valve group and flow speed control valve group 911；Described collection
Valve group is become to include check valve 904, single flow overflow valve 905, shock-proof pressure gauge 906, stop valve 907, hand-operated direction valve 908, double
