Technical field
The utility model relates to the technical field of blade of wind-driven generator strength test, refers in particular to the adapter flange that a kind of blade of wind-driven generator strength test is used.
Background technology
Current, wind-power electricity generation, as a kind of energy industry of environmental protection, in the society of modern energy anxiety, more and more comes into one's own, also increasing to the investment of aerogenerator.Known in the industry, in wind power equipment, the blade of aerogenerator is very important critical component, and its performance directly determines power and the serviceable life of wind power generating set.For reducing the cost of electricity-generating of wind-powered electricity generation, Wind Power Generation Industry is more and more higher to the requirement of single-machine capacity, and the every growth by 6% of blade, and its wind energy of catching can increase by 12%, and therefore, the blade that aerogenerator uses is also to maximization future development.At present, along with the increase of length of blade, the test of blade of wind-driven generator static strength is loaded by single-point the earliest, one direction test, and multiple spot till now loads, multi-direction coupling measurement; Compared with loading with one direction, this method can produce more realistic shear-type load, most of region of blade is tested at one time, can realize easily and be loaded on failure test, and can determine ultimate strength, design margin or the flexion limit of blade.But this installation to blade is had higher requirement, general ring flange need to all be pulled down blade and flange now, and then by blade rotation to the angle of specifying, although and the efficient expense of pitch variable bearings is too high, limited production and the application of large-scale wind electricity use blade.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of reliable, easy for installation, cost is low, long service life, blade of wind-driven generator strength test that efficiency is high are used adapter flange rational in infrastructure is provided, can, in the situation that not dismantling blade, complete rapidly the adjustment of blade angle.
For achieving the above object, technical scheme provided by the utility model is: the adapter flange that a kind of blade of wind-driven generator strength test is used, described adapter flange adopts inside and outside nested type Double-layer flange structure, include inner flange, outside flange, slider roller, adjusting screw, wherein, the inner ring of described outside flange is provided with multiple along its circumferential slider roller installation position spaced apart, described slider roller is arranged on corresponding slider roller installation position, the outer ring of each slider roller installation position and outside flange is all through with adjusting screw mounting hole, described adjusting screw is inserted on corresponding adjusting screw mounting hole, and be connected with corresponding slider roller, by tightening or unclamping adjusting screw, can make slider roller contact with inner flange or separate, described inner flange is connected with the blade of aerogenerator by bolt, and described outside flange is connected with the testing table of blade strength test use by bolt.
Described multiple slider rollers installation position equi-spaced apart is arranged.
On described inner flange, be circumferentially with a circle bolt hole along it.
On described outside flange, be circumferentially with a circle bolt hole along it.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
1, in experimentation, do not need blade to pull down testing table, just can carry out the adjustment of blade angle, adopt inside and outside nested type Double-layer flange structure, the pattern of slider roller can be rotated inner flange, thereby can adjust rapidly blades installation angle, efficiently convenient;
2, inner flange can be changed according to different blades, applied range, and cost is low.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figures 1 to 8, the adapter flange that blade of wind-driven generator strength test described in the present embodiment is used, adopt inside and outside nested type Double-layer flange structure, include inner flange 1, outside flange 2, slider roller 6, adjusting screw 3, wherein, the inner ring of described outside flange 2 is provided with four slider roller installation positions 201 of equidistantly arranging along its circumferential interval, described slider roller 6 is arranged on corresponding slider roller installation position 201, and each slider roller installation position 201 is all through with an adjusting screw mounting hole 202 with the outer ring of outside flange 2, described adjusting screw 3 is inserted on corresponding adjusting screw mounting hole 202, and be connected with corresponding slider roller 6, by tightening or unclamping adjusting screw 3, can make slider roller 6 contact or separate with inner flange 1, and under normality, described slider roller 6 keeps separating with inner flange 1, do not produce contact, on described inner flange 1, be circumferentially with a circle bolt hole 101 along it, be fixedly connected by the blade 4 that high-strength bolt and aerogenerator are installed, meanwhile, described inner flange can be changed according to different blades, applied range, and cost is low, on described outside flange 2, be circumferentially with a circle bolt hole 203 along it, be fixedly connected by the testing table 5 that high-strength bolt and blade strength test use are installed.After designing more than adopting, in experimentation, in the time that needs are adjusted blade 4 angle, only need tighten all adjusting screw 3, whole slider rollers 6 can be contacted with the outer ring of inner flange 1, can, by rotation inner flange 1, blade 4 be adjusted to the test angle of requirement, and after adjusting, unclamp all adjusting screw 3, whole slider rollers 6 are not contacted with inner flange 1, can carry out the strength test of blade 4, whole process does not need blade 4 to pull down testing table 5, simple and efficient to handle.
