Embodiment Construction
[0028] The present invention will be further described below in conjunction with specific embodiments.
[0029] See Figure 1 to Figure 5 As shown, the foundation anchor bolt reinforcement structure of the wind power generator provided by this embodiment includes a force transmission beam 1, a cushion block 2, a support plate 3, and an inner anchor plate 5, an outer anchor plate 6, and PVC that are matched with the anchor bolt 4. Casing 7; on the wall of the tower 8 of the wind turbine, a beam mounting hole 9 close to the bottom of the tower 8 is opened, specifically an elliptical hole, the force transmission beam 1 passes through the beam mounting hole 9, which One part is located inside the tower tube 8 and the other part is located outside the tower tube 8. The two parts are respectively supported by the supporting plate 3, which abuts against the bottom flange 10 of the tower, and can transmit the pre-tightening force of the anchor bolt 4 To the bottom flange 10 of the tower...

The invention discloses a wind power electric generator foundation anchor bolt reinforcing structure and a foundation anchor bolt fracture reinforcing method. The structure comprises a force transferring beam, pad blocks, supporting plates, an inner anchor plate, an outer anchor plate and PVC sleeve pipes, the tube wall of a tower tube is provided with a beam installation hole which is close to the bottom of the tower tube, the force transferring beam is arranged inside the beam installation hole in a penetrating manner and is supported by the supporting plates, the position, in contact with the tube wall, of the force transferring beam is provided with the upper pad block and the lower pad block, the inner anchor plate and the outer anchor plate are arranged on the top of the force transferring beam and are connected with anchor bolts correspondingly, the upper portions of the anchor bolts are wrapped by the PVC sleeve pipes, the lower portions of the anchor bolts are exposed, after the exposed portions of the anchor bolts are put into foundation open holes, grouting materials are poured, the anchor bolts and foundation concrete are made to be combined together, the PVC sleeve pipes extend into anchor bolt holes of the inner anchor plate and the outer anchor plate, and the anticorrosive protection effect performed on the anchor bolts is achieved. By means of the wind power electric generator foundation anchor bolt reinforcing structure and the foundation anchor bolt fracture reinforcing method, underground construction is avoided, and the problem of anchor bolt fracture issolved with low cost and high efficiency.
Description
Technical field [0001] The invention relates to the technical field of maintenance of foundation anchor bolt fracture of a wind generator, in particular to a foundation anchor bolt reinforcement structure of a wind generator and a foundation anchor bolt fracture reinforcement method. Background technique [0002] The anchor bolt foundation is a commonly used foundation type for wind turbines. Under this basic structure form, the entire load of the unit is transferred to the foundation concrete part through the foundation anchor bolt. Compared with the basic ring fan foundation, the anchor bolt foundation avoids sudden changes in the rigidity of the foundation connection position, and the force is more reasonable. However, the anchor bolt foundation also has great disadvantages, that is, it is difficult to replace the anchor bolt after it is broken. Moreover, when the anchor bolt breaks, the anchor bolt near the break location will break with a tendency of gradually accelerating ...
