Abstract
The present invention relates to a kind of wind driven generation set main shaft locking synchronization hydraulic system, it comprises one-way valve, selector valve, locking cylinder, selector valve described in 1:1 flow divider-combiner is 3-position 4-way meta M type selector valve, the pressure port P of 3-position 4-way meta M type selector valve communicates with the outlet of one-way valve, the oil return inlet T of 3-position 4-way meta M type selector valve communicates with fuel tank, two oil outlet P1 and P2 of 3-position 4-way meta M type selector valve communicate with the filler opening of flow divider-combiner and the outlet of two locking cylinders respectively, two oil outlets of flow divider-combiner communicate with the oiler of two locking cylinders respectively.The hydraulic oil that oil hydraulic pump of the present invention pumps is by 3-position 4-way meta M type selector valve, then through flow divider-combiner shunting, the 1:1 of hydraulic oil according to default is shunted, 2 locking cylinders, thus the stroke of two locking cylinders is identical reaches synchronous, reach the high reliability synchro system of designing requirement.
Description
Technical field
The present invention relates to wind-driven generator field, particularly relate to a kind of wind driven generation set main shaft locking synchronization hydraulic system.
Background technique
Along with the power of Megawatt fan strengthens gradually, special in direct-driving type wind power generation unit, when safeguarding wheel hub, inevitably need to lock the main shaft that namely wheel hub locks wind power generating set, thus ensure the safety of attendant, in order to reach this function, industry generally adopts manual pump or the single spring bolt of electric pump type to lock wheel hub, when required locking moment cannot meet the demands, can only by strengthening the diameter of spring bolt, due to spring bolt enlarged diameter, cause complete machine interface size can corresponding increase, now just need to use 2 spring bolts simultaneously, when use 2 spring bolts, existing wind driven generation set main shaft locking hydraulic system is shown in accompanying drawing 2, generally comprise fuel tank 1, level meter 3, air filter 2, hand pump 4, relief valve 5, one-way valve 6, tube type cut-off valve 7, pressure gauge 8, two-position four way change valve 13, locking cylinder I 11 and locking cylinder II 12.The oil outlet of hand pump 4 communicates with the filler opening of one-way valve 6, the relief valve 5 communicated with fuel tank 1 is provided with between hand pump 4 oil outlet with one-way valve 6 filler opening, the oil outlet of one-way valve 6 communicates with the filler opening of two-position four way change valve 13, two oil outlets of two-position four way change valve 13 communicate with the filler opening of locking cylinder I 11 and locking cylinder II 12 and return opening respectively, and the return opening of two-position four way change valve 13 communicates with fuel tank 1.Because locking cylinder I 11 and locking cylinder II 12 are in parallel, the hydraulic oil entering two locking cylinder rodless cavities often occurs that flow is different, namely locking cylinder piston rod stretches out displacement difference, be easy to like this cause single locking cylinder piston rod stand under load excessive, locking cylinder piston rod such as to cut off at the situation, even cause hazard to person, existing principal shaft locking system cannot accomplish that 2 locking cylinders lock the high reliability request of wheel hub guarantor person safety simultaneously.
Summary of the invention
The object of the invention is to overcome above defect, provide a kind of structure simple, the wind driven generation set main shaft locking synchronization hydraulic system of reliable lock.
The present invention is achieved by the following technical solutions: a kind of wind driven generation set main shaft locking synchronization hydraulic system, it comprises one-way valve, selector valve, locking cylinder, also comprise flow divider-combiner, described selector valve is 3-position 4-way meta M type selector valve, described flow divider-combiner is 1:1 flow divider-combiner, the pressure port P of 3-position 4-way meta M type selector valve communicates with the outlet of one-way valve, the oil return inlet T of 3-position 4-way meta M type selector valve communicates with fuel tank, two oil outlet P1 and P2 of 3-position 4-way meta M type selector valve communicate with the filler opening of flow divider-combiner and the outlet of two locking cylinders respectively, two oil outlets of flow divider-combiner communicate with the oiler of two locking cylinders respectively.
Preferably, be equipped with at two of flow divider-combiner the relief valve communicated with fuel tank between oil outlet and the oiler of locking cylinder.
Advantageous Effects of the present invention is, owing to having set up 3-position 4-way meta M type selector valve, flow divider-combiner, the hydraulic oil that oil hydraulic pump pumps is by 3-position 4-way meta M type selector valve, then shunt through flow divider-combiner, shunted by the 1:1 of hydraulic oil according to default, the hydraulic oil through average shunting enters 2 locking cylinders respectively, and flow is depended in the displacement of locking cylinder, now the stroke of two locking cylinders is identical reaches synchronous, reaches the high reliability synchro system of designing requirement.And set up relief valve respectively in two outlets of flow divider-combiner, thus protect the safety of system.
