Problems solved by technology

[0004] However, when the anchor bolt 3 is installed on the lower anchor plate 2, since the anchor bolt 3 belongs to the cantilever structure at this time, even if the steel nut at the lower end of the anchor bolt 3 is tightened , the anchor bolt 3 will also have more or less deflection, which will lead to the overall torsion of the anchor bolt 3 around the vertical line in the anchor bolt cage, and installation quality problems such as the horizontal misalignment of the upper and lower anchor plates, which will also affect the final vertical position of the anchor bolt. accuracy, which in turn affects the quality of the foundation and changes the stress state of the anchor bolts

Abstract

The invention relates to a wind generating set foundation anchor bolt assembly and a construction method of a connecting tower cylinder thereof. The wind generating set foundation anchor bolt assemblycomprises an upper anchor plate, a lower anchor plate, multiple anchor bolts, a supporting casing pipe set and a protecting casing pipe; the anchor bolts are connected with the upper anchor plate andthe lower anchor plate, the supporting casing pipe set comprises a first supporting pipe, a second supporting pipe and a connecting pipe fixedly connected with the first supporting pipe and the second supporting pipe, two adjacent anchor bolts are sleeved with the first supporting pipe and the second supporting pipe correspondingly, the upper anchor plate is supported by the first supporting pipeand the second supporting pipe, the protecting casing pipe is arranged on remaining anchor bolts in a sleeving manner, two adjacent anchor bolts are sleeved with the integrated supporting casing pipeset, deviation of the anchor bolts in the horizontal direction after the anchor bolts are arranged on the upper anchor plate and the lower anchor plate can be limited, whole torsion deforming of theanchor bolts around a vertical shaft of the foundation anchor bolt assembly is avoided, whole precision of the wind generating set foundation anchor bolt assembly is improved, the quality of the windgenerating set foundation anchor bolt assembly is improved, and the tower cylinder lifting difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a foundation anchor bolt assembly of a wind power generating set and a construction method for connecting it to a tower. Background technique [0002] Anchor-bolted foundation is a structural form widely used in the land foundation of wind turbines. Compared with the foundation ring foundation, the force of the anchor bolt foundation is more reasonable. Because the appearance of the anchor bolt assembly in the anchor bolt foundation resembles a birdcage, the anchor bolt assembly is also called the anchor bolt cage. [0003] Such as figure 1 As shown, the existing anchor bolt assembly includes an upper anchor plate 1, a lower anchor plate 2, a plurality of anchor bolts 3, a PVC sleeve (not shown), steel nuts and nylon nuts 5 (see figure 2 ). The upper anchor plate 1 and the lower anchor plate 2 are both ring-shaped, and are respectively provided with a first annular hole g...
