Abstract
The utility model relates to a kind of hydraulic driving assembly, comprise a pair of bar piston hydraulic cylinder, the end of two piston rods of described pair of bar piston hydraulic cylinder is all connected with two connecting rods, one end of described every connecting rod is connected with push rod, the described pair of horizontal or vertical installation of bar piston hydraulic cylinder, the installation direction of described push rod is vertical with the installation direction of two bar piston hydraulic cylinders.By adopting two bar piston hydraulic cylinders to promote four push rods, the middle connecting rod that adopts carrys out transmission, compares and adopts four single pole double-acting hydraulic cylinders, can complete well usage requirement on the one hand, more stable, convenient; Reduce on the other hand cost.
Description
Technical field
the utility model relates to hydraulics field, relates in particular to a kind of hydraulic driving assembly.
Background technique
in engineering machinery, adopt hydraulics more at present, in the time carrying out to-and-fro motion, adopt oil hydraulic cylinder to drive more.Oil hydraulic cylinder by hydraulic energy change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).Its simple in structure, reliable operation.While realizing to-and-fro motion with it, can remove speed reducer from, and there is no drive gap, motion steadily, is therefore used widely in the hydraulic system of various machineries.The pressure reduction on oil hydraulic cylinder ouput force and piston effective area and both sides thereof is directly proportional; Oil hydraulic cylinder is made up of cylinder barrel and cylinder cap, piston and piston rod, seal arrangement, damping device and venting gas appliance substantially.
in prior art, an oil hydraulic cylinder is generally only used for driving a moving element, in the time that multiple moving elements use simultaneously, can only adopt multiple oil hydraulic cylinders, has improved cost.
Model utility content
the utility model, in order to overcome deficiency of the prior art, provides a kind of hydraulic driving assembly, can drive four moving elements simultaneously, reduces costs.
the utility model is to be achieved through the following technical solutions:
a kind of hydraulic driving assembly, comprises a pair of bar piston hydraulic cylinder, and the end of two piston rods of described pair of bar piston hydraulic cylinder is all connected with two connecting rods, and one end of described every connecting rod is connected with push rod.
as optimal technical scheme of the present utility model, the described pair of horizontal or vertical installation of bar piston hydraulic cylinder.
as optimal technical scheme of the present utility model, the installation direction of described push rod is vertical with the installation direction of two bar piston hydraulic cylinders.
as optimal technical scheme of the present utility model, all hinged by bearing pin between described piston rod and connecting rod and connecting rod and push rod.
compared with prior art, the beneficial effects of the utility model are: by adopting two bar piston hydraulic cylinders to promote four push rods, the middle connecting rod that adopts carrys out transmission, compare and adopt four single pole double-acting hydraulic cylinders, can complete well usage requirement on the one hand, more stable, convenient; Reduce on the other hand cost.
Brief description of the drawings
fig. 1 is structural representation of the present utility model.
in figure: the two bar piston hydraulic cylinders of 1-; 2-piston rod; 3-connecting rod; 4-push rod; 5-bearing pin.
Embodiment
in order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
described a kind of hydraulic driving assembly, comprises a pair of bar piston hydraulic cylinder 1, and this oil hydraulic cylinder is provided with liquid entering hole and liquid outlet, is connected respectively with liquid inlet pipe and drain pipe.The end of two piston rods 2 of described pair of bar piston hydraulic cylinder 1 is all connected with two connecting rods 3, and one end of described every connecting rod 3 is connected with push rod 4.By adopting two bar piston hydraulic cylinders to promote four push rods, the middle connecting rod that adopts carrys out transmission, compares and adopts four single pole double-acting hydraulic cylinders, can complete well usage requirement on the one hand, more stable, convenient; Reduce on the other hand cost.
the described pair of horizontal or vertical installation of bar piston hydraulic cylinder 1, the installation direction of described push rod 4 is vertical with the installation direction of two bar piston hydraulic cylinders 1.
preferably, all hinged by bearing pin 5 between described piston rod 2 and connecting rod 3 and connecting rod 3 and push rod 4, hinged reliable.
the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
