The utility model provides a wind turbine blade frock, in quiet power loading procedure, not only can with load uniform distribution on wind turbine blade frock, the error of guaranteeing loading load and command moreover reachs reasonable real tentation data at less within range to rational in infrastructure, processing ease, convenient and practical have better using value.
Description
Technical field
The utility model relates to a kind of wind wheel blade frock, belongs to new energy technology application.
Background technology
Along with the increase of length of blade, in large-scale wind wheel blade slow test loading procedure, the deflection at blade tip position is increasing.Tradition layback test tool load(ing) point is near side, power source, the frock of opposite side is delivered to by bolt, then blade is passed to, there is the excessive situation of stress in connecting hole, bolt etc. like this for layback frock, increase the danger coefficient of each parts of layback frock, so traditional layback frock is also labor intensive, material resources in manufacturing process.
Tradition layback frock passes through the hole of different interval as the load(ing) point on blade, and produces the error that can not solve because the distance between hole makes to act on load(ing) point and target load(ing) point on blade string of a musical instrument direction.3-4 layback frock is needed in general large-scale wind wheel blade finite element analysis process, be installed on blade different cross section position, for the layback frock near blade tip side, due to the large distortion of blade on loading direction and frock load(ing) point distance blade center comparatively far away, cause load(ing) point to produce at blade axial direction and depart from more greatly.In addition, because layback frock rigidity is comparatively large, in the transmittance process of power, not only blade produces larger displacement, and layback frock also produces less desirable rotation phenomenon, thus occurs extra moment of flexure, increases load error.
Utility model content

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model and the mode of action are described further.
Shown in Fig. 1-Fig. 2, a kind of wind wheel blade frock 10, comprises frock main body 4, the conformal wood clamp heart 6, wire rope 1 and clamping plate 5, described frock main body 4 is provided with multiple bolt hole coordinated with the first bolt 2 and the second bolt 3.
Described frock main body 4 comprises the laterally zygomorphic upper frock main body 41 of structure and lower frock main body 42, be plane in the middle of upper frock main body 41 and lower frock main body 42, both sides are in the flange extended internally, thus make frock main body 41 and lower frock main body 42 in conjunction with the inner space of a rear formation coated wind wheel blade of energy, the outer ledge of each flange stretches out and is provided with web joint, described web joint is provided with hole, and upper frock main body 41 and lower frock main body 42 are fixed through this hole by the first bolt 2.
The described conformal wood clamp heart 6 comprises laterally zygomorphic two of structure, it is inner that these two conformal wood clamp hearts 6 are connected to frock main body 4 respectively by the second bolt 3, namely a conformal wood clamp heart is connected to frock main body 41 inside, and it is inner that another conformal wood clamp heart is connected to lower frock main body 42.The external structure of the described conformal wood clamp heart 6 is corresponding with the inner structure of described frock main body 4, and the inner structure of the described conformal wood clamp heart 6 is corresponding with the structure of described wind wheel blade, to form the wind wheel blade frock 10 coordinated with corresponding wind wheel blade.
It is outside that described wire rope 1 is fixedly mounted on described frock main body 4 by clamping plate 5, thus avoid wire rope 1 in process of the test to produce axis and tangential slip, preferably, described wire rope 1 is positioned at the position, middle part of frock main body 4 outside, then, blade 8 is fixed on testing table 7, wire rope 1 two ends is connected with power source 9 and loads.By the design of wire rope 1, uniform load can be distributed in wind wheel blade frock 10, and will just need not be delivered to back in the wind wheel blade frock 10 of side, power source 9 to the loading force of side, power source 9 by coupling bolt, avoid a certain position of wind wheel blade frock 10 or coupling bolt to produce stressed concentration phenomenon, reduce the requirement of test to wind wheel blade frock 10 structural strength.
During concrete enforcement, because blade is in process of the test, less desirable axial torsion can be produced, displacement etc., minimum in order to ensure this tangent plane torsion angle, so need the length of reasonable distribution two wire rope, to ensure that load(ing) point extended line is positioned at blade in the elastic center of this tangent plane, therefore the described wire rope 1 distribution in the longitudinal direction target load(ing) point corresponding to blade slow test loading procedure is needed to adapt, namely the length of wire rope 1 can meet after the two ends of wire rope 1 are connected with corresponding target load(ing) point, it at least can along frock main body 4 external rings around a circle, it is made to have enough length to meet above-mentioned purpose, distance between simultaneously avoiding further due to hole makes to act on the error between load(ing) point on blade 8 string of a musical instrument direction and target load(ing) point.
Upper frock main body 41 and lower frock main body 42 are respectively provided with multiple clamping plate 5, the quantity of upper frock main body 41 and lower frock main body 42 train wheel bridge 5 can be set to two, three or four respectively, certainly, also can be set to more, wire rope 1, not as limit, can be fixed in frock main body 4 as long as meet by the utility model, each clamping plate 5 are positioned at the middle part of frock main body 4 outside, each clamping plate 5 are provided with two bolts hole, simultaneously, described frock main body 4 is provided with the bolt hole that multiple and each clamping plate 5 are equipped with, the aperture of each bolt hole and position corresponding with the bolt hole on clamping plate, each clamping plate 5 and upper frock main body 41, lower frock main body 42 connects respectively by two bolts, described wire rope 1 is middle with frock main body 4 around being through at each clamping plate 5, and between two bolts be through on each clamping plate 5, thus wire rope 1 can be stablized be fixed on outside frock main body 4, uniform load can be delivered in wind wheel blade frock 10 simultaneously.
In blade 8 front edge side and trailing edge side; described wind wheel blade frock 10 inside is formed circular; thus reasonable distribution load; avoid blade 8 trailing edge side to depart from more greatly because frock load(ing) point distance blade 8 center comparatively far produces on blade 8 axial direction simultaneously; and avoid wind wheel blade frock 10 produce rotation phenomenon and occur extra moment of flexure, protection wind wheel blade frock 10.
To sum up, the wind wheel blade frock 10 that the application provides, by said structure, makes wire rope 1 act on the periphery of wind wheel blade frock 10, make loading force be uniformly distributed in wind wheel blade frock 10 surface, avoid a certain position of wind wheel blade frock 10 or coupling bolt to produce stressed concentration phenomenon.It significantly can reduce the requirement of test to wind wheel blade frock 10 structural strength, simple, reliable, and is easy to install.In addition, the load(ing) point of blade on string of a musical instrument direction can accurate Calculation, thus reduces error, draws rationally real test figure.The loading force that is uniformly distributed that load acts in frock compares traditional frock distance blade center comparatively closely, reduces the load error on blade axial direction.
These are only preferred embodiment of the present utility model; protection domain of the present utility model can not be limited with this; namely the simple equivalence generally made according to the utility model claims and utility model content changes and amendment, all still belongs to the protection domain of the utility model patented claim.
