Abstract

The utility model relates to a pulling down device for strength test of a wind power blade. The pulling down device comprises a plurality of pulling down hooks which are distributed on the bottom surface of a wind power blade, and a traction mechanism arranged below the pulling down hooks; and a pulling rope is arranged between each pulling down hook and the traction mechanism. The bottom of the traction mechanism is arranged on an H-shaped base, and sliding blocks are arranged at four end parts of the H-shaped base; and various sliding blocks are connected to a pair of reverse T-shaped chutes through bolts; during testing, the position of the H-shaped base can be regulated just by releasing the bolts on the various sliding blocks, so as to draw different parts of the wind power blade to implement corresponding strength test. The traction mechanism comprises a roller for winding the pulling rope and a guide wheel which is arranged in the center of the front side of the roller; and the bottom of the supporting frame of the guide wheel is arranged on a movable shaft. When the pulling down device is used, the guide wheel is adapted to steer in real time, thereby being conductive to controlling direction of the pulling rope.

Description

The strength test pull device of wind electricity blade

Technical field

The utility model relates to the technical field of carrying out torture test and strength testing facility for the standard specimen that the wind electricity blade material is made, specifically a kind of strength test pull device of wind electricity blade.

Background technology

In prior art, the equipment that the standard specimen that shortage is made the wind electricity blade material carries out torture test and strength test also lacks relevant industry standard.Therefore, how providing the strength test device of the higher wind electricity blade of a kind of reliability, to reach experiment purpose, is the technical matters of this area.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of strength test pull device of simple in structure, wind electricity blade that reliability is higher.

For solving the problems of the technologies described above, the utility model provides a kind of strength test pull device of wind electricity blade, and it comprises: be distributed in a plurality of lower drag hook on the wind electricity blade bottom surface, be located at the draw-off mechanism of lower drag hook below; Be provided with stay cord between lower drag hook and draw-off mechanism.

The bottom of draw-off mechanism is located on a H type base, and four ends of H type base are provided with slide block; Each slide block is bolted on a pair of inverted T-shaped chute that is on the earth's surface; In process of the test, as long as unclamp bolt on each slide block, just can adjust the position of H type base, to realize the tractive to the different parts of wind electricity blade, to carry out corresponding strength test.

Described draw-off mechanism comprises: for cylinder and the angle sheave of being located at this cylinder front center of the described stay cord of reeling; The bottom of the bracing frame of angle sheave is located on a movable axis.During use, angle sheave is suitable for turning in real time, is beneficial to the direction of controlling described stay cord.

The utlity model has positive effect: when the strength test of wind electricity blade of the present utility model was used with pull device, the installation end of wind electricity blade was fixed, and it is unsettled that wind electricity blade is kept flat.Draw-off mechanism is in lower drag hook on the wind electricity blade bottom surface by the stay cord tractive, controls the tension force of stay cord by draw-off mechanism, detects simultaneously tension force and the tractive time of stay cord, to detect the intensity of wind electricity blade; Therefore, pull device of the present utility model has characteristics simple in structure, that reliability is higher.

Embodiment

See Fig. 1-7, the strength test of the wind electricity blade of the present embodiment comprises with pull device: be distributed in a plurality of lower drag hook 2 on wind electricity blade 1 bottom surface, be located at the draw-off mechanism 3 of lower drag hook 2 belows; Be provided with stay cord 4 between lower drag hook 2 and draw-off mechanism 3.

The bottom of draw-off mechanism 3 is located on a H type base 6, and four ends of H type base 6 are provided with slide block 7; Each slide block 7 is bolted on a pair of inverted T-shaped chute 8 that is embedded in advance on the earth's surface; In process of the test, as long as unclamp bolt on each slide block, just can adjust the position of H type base, to realize the tractive to the different parts of wind electricity blade, to carry out corresponding strength test.

Described draw-off mechanism 3 comprises: for cylinder 31 and the angle sheave 32 of being located at these cylinder 31 front center of the described stay cord 4 of reeling; The bottom of the bracing frame 33 of angle sheave 32 is located on a movable axis 34.During use, angle sheave is suitable for turning in real time, is beneficial to the direction of controlling described stay cord 4.

Above-described embodiment is only for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among protection domain of the present utility model.
