Description
Technical field
The utility model relates to a kind of experimental facilities of testing fatigue strength, and particularly wind power generation blade butt built-in fitting and fiberglass cohere fatigue strength test equipment.
Background technology
Wind power generation blade is on-stream, it is to connect the blade root built-in fitting with a circle bolt that blade root connects the unit wheel hub, cohere the well-regulated within the specific limits variation of tensional load size of fatigue strength between built-in fitting and fiberglass, determined whether meet the requirements the serviceable life of this part and cohere fatigue strength between built-in fitting and fiberglass.What the intensity between present domestic built-in fitting and fiberglass was mainly measured is to cohere pulling strengrth, mainly be as a part in the fatigue experiment aspect the experiment of cohering fatigue strength when whole blade is done fatigue experiment, it is big that the deficiency of this quadrat method is to do the experiment cost, cycle is long, also corresponding place and auxiliary facility will be arranged.
The utility model content
The purpose of this utility model is to propose a kind of wind power generation blade butt built-in fitting and fiberglass coheres fatigue strength test equipment, to address the above problem.
Wind power generation blade butt built-in fitting and fiberglass cohere fatigue strength test equipment, it is characterized in that, comprise with the lower part:
One carrier base, described carrier base comprise a vertical plane and a surface level, and the vertical plane of described carrier base is provided with a support, and the surface level of described carrier base is provided with two stands;
One oil cylinder, the support of the vertical plane of described oil cylinder one end and described carrier base flexibly connects;
A plate, described web joint one end and the described oil cylinder other end flexibly connect; Support on the surface level of the described web joint other end and described carrier base flexibly connects;
One experimental piece, an end of described experimental piece and described web joint flexibly connect; Another support on the other end of described experimental piece and the surface level of described carrier base flexibly connects.
Movable connection method between the described each several part is to connect by straight pin.
The end that described experimental piece is connected with described web joint is the built-in fitting end, and the other end that described experimental piece is connected with described web joint is the fiberglass end.
Stretch, contract when motion when the piston of described oil cylinder, drive the left and right swing of described web joint, web joint drives described experimental piece and produces the motion of stretching, contract, and the reciprocal effective degree of this motion cycle is just as the bond test data of fatigue strength of test specimen.
Cohere the experimental facilities of fatigue strength between testing wind power generation blade root built-in fitting provided by the invention and fiberglass, because having adopted oil cylinder is power spare, straight pin is a web member, the bonding fatigue strength that can reflect experimental piece easily, exactly, has effectively improved conventional efficient widely and has reduced experimental expenses widely.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation that wind power generation blade butt built-in fitting described in the embodiment and fiberglass cohere fatigue strength test equipment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to shown in Figure 1, cohere the experimental facilities of fatigue strength between a kind of testing wind power generation blade root built-in fitting and fiberglass, form by carrier base 1, oil cylinder 2, web joint 3, experimental piece 4 and 5 straight pin A, B, C, D, E.

The two ends of experimental piece 4 are that built-in fitting portion 41 and fiberglass portion 42 have mounting hole.Web joint 3 is provided with an experimental piece mounting hole; Straight pin C passes the mounting hole of experimental piece 4 built-in fitting portions 41 and the experimental piece mounting hole on the web joint 3, and an end of experimental piece 4 is installed on the web joint 3.Straight pin E passes the mounting hole of another support on the surface level 12 of the mounting hole of experimental piece 4 fiberglass portions 42 and carrier base 1, and another support on the surface level 12 of the fiberglass portion 42 of experimental piece 4 and carrier base 1 is connected.
Straight pin A, B, C, D, E are a right cylinder, and the right cylinder outer cylinder is a joint face.
When motion is stretched, contracted to the piston rod 22 of oil cylinder 2, driving web joint 3 through the B straight pin is the left and right swing of fulcrum with the D straight pin, web joint 3 drives experimental piece 4 through the C straight pin and produces the stretching varying motions, and the reciprocal effective degree of this motion cycle is just as the bond test data of fatigue strength of test specimen.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
