Description
Technical field
The present invention relates to a kind of wind electricity blade lifting mechanism, and blade lean into act in mountain area for mountain region blade transport vehicle
Rise, in order to by the small section of radius of turn, belong to mountain region wind-powered electricity generation transport of blades technical field.
Background technology
Domestic wind-power market is by fast development in recent years, and the wind energy resources in the preferable Plain region of construction condition is almost
The wind energy totally, developed at present has been developed gradually to the more difficult mountain area of construction condition and marine transfer.But mountain road is narrow,
Radius of turn is small.Collided in order to be effectively prevented from blade with massif, it is necessary to blade is transported in the state of keeping tilting
It is defeated, therefore occur various blade lifting mechanisms in the market.
Generally, barrier is more efficiently avoided for the ease of blade, also needs to enable the 360 ° of revolutions of blade level,
So pivoting support is set between sweep and revolving dial.But this lifting mechanism is when blade is lifted, the center of gravity of blade
Also moved while being raised above to lifting mechanism side.If the vertical line of blade center of gravity was defined to the distance and leaf of certain point
The product of the weight of piece be blade gravity away from if, then blade in lifting process its blade relative to the gravity of pivoting support away from hair
Change is given birth to.That is, blade transport vehicle its equilibrium condition under the level and lifting state of blade is different.Thus
A problem is brought, exactly if being designed to the upper dress portion when blade to be lifted to such as 30 ° of certain angle above pivoting support
It is balance to divide（The center of gravity of upper dress part is on pivoting support axis）, then when blade lifts 30 ° or neighbouring, blade can be with
360 ° of revolutions, but if blade is horizontal positioned, then blade side is overweight, and when making 360 ° of revolutions, vehicle is easy to blade
Topple side.And if being designed on when blade is horizontal positioned that dress part is balance, then can be with when blade is horizontal positioned
360 ° of revolutions, but if blade is lifted into such as 30 ° of certain angle, then counterweight side is overweight, when making 360 ° of revolutions, vehicle
It is easy to topple to counterweight side.
But it is inevitable that when lifting blade, its center of gravity, which rises, therefore, dress portion how is made in blade lifting process
Point center of gravity only rise and it with respect to the gravity of pivoting support away from being held essentially constant or change as far as possible small is exactly that mountain region blade is transported
Defeated car lifting mechanism needs to solve the problems, such as.
Simplest lifting mechanism is a hinged rocking carrier on revolving dial, sets and becomes between rocking carrier and transition disc
Oar pivoting support, is secured the vanes on transition disc, and rocking carrier is promoted around hinged spot wobble by elevating ram, can make blade to
On kick up certain angle.
The blade transport vehicle of special vehicle in the market mainly solves the problem using three kinds of technological approaches at present.One is plus
The weight of big vehicle chassis, makes gravitational moment changing unit-- revolving dial of dress and the weight of lifting mechanism and blade relative
It is smaller, thus make the gravitational moment change of its vehicle in lifting process relatively small；The second is the side of mobile counterweight is set
Method, i.e., mobile counterweight is set on revolving dial, while blade is lifted, automatically or manually mobile counterweight, makes
The center of gravity of dress part is substantially remained on the axis of pivoting support；The third is the method for mobile lifting mechanism, that is, setting to slide
Sliding block and chute, while blade is lifted, make rocking carrier（Lifting mechanism）To the Slideslip of pivoting support one, so that upper dress portion
The center of gravity divided is substantially remained on the axis of pivoting support.
But all there are some defects in these three methods.The problem of first method is present is, due to that must increase vehicle bottom
The counterweight of disk, so complete vehicle weight is larger, and the radius of gyration of revolving dial is larger；Second and the third method existing for ask
Topic is that lifting and center-of-gravity regulating need Liang Ge executing agencies, that is, two groups of hydraulic jacks, also need to match somebody with somebody if automatically controlling
Standby control system, system complex, also easily breaks down.If control manually, then once forgetting center-of-gravity regulating, then making
Vehicle capsizing case easily occurs during 360 ° of revolutions.
Therefore, design one kind only needs set of execution mechanism, makes it when lifting blade, the whole pitching including blade
Partial center of gravity can move along the track for being similar to plumb line, and complete vehicle weight is small and the small blade of sky radius of sweeping of revolving dial is lifted
Rising mechanism just turns into the key technical problem that this area engineers and technicians are badly in need of solving.
The content of the invention
The present invention proposes that its purpose seeks to provide a kind of wind electricity blade lifting mechanism, only makes to solve the above problems
With a set of executive component, make it in blade pitching, the center of gravity of its pitching part is along being approximately that the track of plumb line moves up and down.

Hack lever and connecting rod ASSY form four-bar mechanism；Connecting rod ASSY is made up of rocking carrier, side stand, pitching slewing support and transition disc；
Revolving dial is arranged on frock chassis by pivoting support；The front end that one end of preceding side link passes through hinge and revolving dial
Be hinged, the other end is hinged by the front end of hinge and connecting rod ASSY, after one end of rear side link is by hinge and revolving dial
End is be hinged, and the other end is hinged by the rear end of hinge and connecting rod ASSY；Pass through the initial position that four-bar mechanism is set and each bar bar
Long, making connecting rod ASSY, the point A energy edge on the extended line of connecting rod ASSY is similar to plumb line when being moved by driving element driving
Track B movement；In transporting blade, blade is arranged on the transition disc of connecting rod ASSY rear end, and blade weight counterbalance is arranged on connecting rod
Pitching assembly is formed on the rocking carrier of assembly front end, overlaps the point A in the center of gravity of pitching assembly and the extended line of connecting rod ASSY.
Pivoting support is arranged on the underface of revolving dial and pitching assembly center of gravity.
Driving element is elevating ram.
Driving element is arranged between revolving dial and side stand.
Driving element is arranged between revolving dial and rear side link.
The beneficial effects of the invention are as follows：Because blade lifting mechanism is four-bar mechanism, it is only necessary to a set of driving element, so
The problem of coordinating in the absence of Liang Tao executing agencies；Pitching assembly is formed due to making blade and connecting rod ASSY link into an integrated entity, is made
During blade pitching, the center of gravity of its pitching assembly moves along the track for being similar to plumb line, so, pitching assembly is with respect to pivoting support
