Abstract
The utility model relates to a pull-down device for a wind turbine blade strength test. The pull-down device is characterized by comprising a base, wherein a turntable is arranged on the base through a rotating shaft; a locking mechanism used for limiting the relative position between the turntable and the base is arranged between the turntable and the base; a winding machine is arranged on the turntable; a radial bracket is arranged on one side of the winding machine on the turntable; a guide wheel assembly is arranged on the radial bracket and is arranged on the radial bracket through a fastening piece. The utility model discloses the new pull-down device used for testing the strength of a blade; the pull-down device can facilitate the adjustment of the pull-down direction of the blade, meanwhile, the blade is tested in all directions, and the test effect is better.
Description
Technical field
The utility model wind power equipment pick-up unit technology belongs to field, particularly relates to a kind of strength test pull device of wind electricity blade.
Background technology
At present, wind-power electricity generation, belongs to the lustration type energy, is that the useful of thermal power generation supplemented, but because current its cost on manufacturing is higher and be subject to the impact of other technical factor, adopts not yet on a large scale.
Blade is critical piece on aerogenerator, in prior art, lacks the equipment that the standard specimen of wind electricity blade material making is carried out to torture test and strength test, also lacks relevant industry standard.Therefore, how providing the strength test device of the wind electricity blade that a kind of reliability is higher, to reach the object of experiment, is the technical matters of this area.At present, pull the angle of blade to be difficult for adjusting for the device of the strength test of wind electricity blade, test comprehensive not.
Summary of the invention
The utility model for solve the technical matters existing in known technology provide a kind of simple in structure, reliability is high, pull angle to be convenient to the strength test pull device of the wind electricity blade regulating.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of strength test pull device of wind electricity blade, comprise, it is characterized in that: comprise base, on described base, by rotating shaft, rotating disk is installed, between described rotating disk and described base, is provided with the locking mechanism for limiting relative position between rotating disk and base; On described rotating disk, winder is installed, is positioned at described winder one side and is provided with radial struts on described rotating disk, in described radial struts, guide wheel assemblies is installed, described guide wheel assemblies is arranged in described radial struts by securing member.
The utility model can also adopt following technical scheme:
Preferably, be evenly equipped with the deep-slotted chip breaker centered by described rotating shaft on described rotating disk, described domain is provided with the clamping screw that connects described deep-slotted chip breaker, on described clamping screw, set nut is installed.
Preferably, described radial struts is provided with radially elongated slot, and described guide wheel assemblies is arranged in described radial struts by running through the screw bolt and nut of described elongated slot.
Advantage and the good effect that the utlity model has are: a kind of new pull device for pilot blade intensity of the utility model design, this pull device can be so that the drop-down direction of adjusting vane, the comprehensive test to blade on one side, test better effects if.
Accompanying drawing explanation

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of strength test pull device of wind electricity blade, comprises base 1, and base 1 is located at the below of tested blade.On described base 1, by rotating shaft 2, rotating disk 3 is installed, between described rotating disk 3 and described base 1, is provided with the locking mechanism for limiting relative position between rotating disk 3 and base 1.Winder 4 is installed on described rotating disk, on winder 4, is wound with bracing wire, winder 4 is power sources of bracing wire.On described rotating disk 3, be positioned at described winder 4 one sides and be provided with radial struts 5, in described radial struts 5, guide wheel assemblies 6 is installed, described guide wheel assemblies 6 is arranged in described radial struts 5 by securing member.The free end of the bracing wire on winder 4 is through the covert tested pilot that connects blade of guide wheel assemblies 6.In this enforcement, can adjust the force direction that reels of blade by the distance between rotary turnplate 3 and adjustment guide wheel assemblies 6 and rotating shaft 2, complete multi-direction test with this.
The concrete structure of above-mentioned locking mechanism is: on described rotating disk 3, be evenly equipped with the deep-slotted chip breaker 7 centered by described rotating shaft 2, described chassis 1 is provided with the clamping screw that connects described deep-slotted chip breaker 7, on described clamping screw, set nut is installed.The relative position between rotating disk and base can be fixed and adjust to above-mentioned clamping screw and set nut.
Described radial struts 5 is provided with radially elongated slot 8, and described guide wheel assemblies 6 is arranged in described radial struts 5 by running through the screw bolt and nut of described elongated slot.Loose bolts and nut assembly just can be adjusted the distance between guide wheel assemblies 6 and winder 4, to adjust the stretching angle of bracing wire.
Above-described embodiment is only for the utility model example is clearly described; and be not the restriction to embodiment of the present utility model; for the those of ordinary skill in described field; can also make on the basis of the above description other multi-form variation; here exhaustive without also giving all embodiments, and these belong to apparent variation that spirit of the present utility model amplified out or variation still among protection domain of the present utility model.
