The fixing tool comprises a rectangular frame made of metal sectional material, wherein the rectangular frame is composed of two transverse frames and two vertical frames, and the transverse frames are fixedly connected with the vertical frames through bolts; an upper pressing block and a lower pressing block are respectively mounted on the two vertical frames and are arranged on the inner side of the rectangular frame, the upper pressing block is provided with an arc surface which is used for pressing the upper surface of the wind power blade and is capable of being attached to the upper surface of the wind power blade, and the lower pressing block is provided with an arc surface which is used for bearing the lower surface of the wind power blade and is capable of being attached to the lower surface of the wind power blade; a side top block is arranged on each vertical frame, and each side top block is provided with an arc surface attached to the outer side face of the wind power blade; the transverse frames and the vertical frames are provided with lifting lugs, the lifting lugs are positioned on the outer side of the rectangular frame, and a hole is formed in each lifting lug. The fixing tool has the advantages of being simple in structure and reliable to fix, and being incapable of damaging wind power blade test pieces.
Description
Technical field
The utility model belongs to wind power equipment and detects servicing unit technical field, particularly relates to a kind of wind electricity blade strength test fixing tool.
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 the critical piece on aerogenerator, the standard specimen that wind electricity blade material is made carries out in the process of torture test and strength test, need to utilize draw-gear to apply pulling force to the different parts of wind electricity blade test specimen, in prior art, conventionally utilize the tested position of wire rope binding wind electricity blade test specimen, draw-gear pulls wire rope to complete test, in the process of test, the pulling force of draw-gear is larger, wire rope can produce and strangle trace on wind electricity blade test specimen, damage wind electricity blade test specimen.
Summary of the invention
The utility model for solve the wind electricity blade test specimen existing in known technology in the process of test easily impaired technical matters provide a kind of simple in structure, fixing reliably, can not cause to wind electricity blade test specimen the wind electricity blade strength test fixing tool of damage.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of wind electricity blade strength test fixing tool, it is characterized in that: comprise the rectangular frame that shape forms, described rectangular frame is made up of two crossbearers and the vertical frame vertical with two crossbearers, and described crossbearer and vertical frame are bolted to connection; On described two crossbearers, be separately installed with upper holder block and lower lock block, described upper holder block and lower lock block are located at the inner side of described rectangular frame, on described upper holder block, there is the cambered surface that can fit with wind electricity blade of pressing above wind electricity blade for pushing up above, on described lower lock block, have for the cambered surface that can fit below with wind electricity blade below support wind electricity blade; Side jacking block is installed in described vertical frame, and described side jacking block has the cambered surface with the laminating of wind electricity blade lateral surface; Described crossbearer and vertical frame are provided with hanger, and described hanger is positioned at the outside of described rectangular frame, on described hanger, have hole.
The utility model can also adopt following technical scheme:
Preferably, described section bar is H shaped steel.
Preferably, the cambered surface place on described upper holder block, lower lock block and side jacking block is provided with rubber blanket.
Advantage and the good effect that the utlity model has are: 1. fixing-stable: this frock is by rectangular frame and be located at upper holder block, lower lock block and side jacking block in rectangular frame and the test specimen of wind electricity blade is carried out to surrounding enclosed fix, compare the strap-on fixed form of traditional wire rope, this device fixed effect better, more stable, be conducive to test carrying out.2. can not damage the test specimen of wind electricity blade: in this device, upper holder block, lower lock block and side jacking block contact by the larger cambered surface of area with the outside surface of wind electricity blade, stressed larger in the situation that, can prevent the test specimen damage wind electricity blade for fixing wind electricity blade, can effectively avoid wind electricity blade impaired in the process of check.
