Embodiment 1

[0037] As a typical implementation of the present invention, please refer to figure 1 and Figure 5 , a connector for anchor bolt connection, including a nut-fixed connector 100, the nut-fixed connector 100 adopts an annular plate structure, and two circles of hexagonal holes are opened on the annular plate, which are respectively an inner ring 102 and an outer ring 101 , the inner indexing circle 105 and the outer indexing circle 106 of the hexagonal hole are consistent with the indexing circle of the anchor bolt opening on the lower anchor plate 500, and the number of hexagonal holes and the anchor bolt openings on the lower anchor plate 500 same.

[0038] The hexagonal hole on the nut fixing connector 100 in this embodiment is perforated according to the nut 601 on the anchor bolt, and the size of the opposite side of the hexagonal hole is 1-3 mm larger than the size of the hexagonal side of the nut 601. The hexagonal hole on the nut fixing connector 100 limits the rotati...

Embodiment 2

[0061] As a typical implementation, please refer to figure 1 and Figure 4 , this embodiment provides an anchor bolt system that is easy to replace, including an anchor bolt assembly, an anchor bolt fixing connector 800, a nut fixing connector 100, a bolt nut 200, a wrench, and a pipe wrench; the anchor bolt assembly includes an anchor bolt assembly Bolt 300 and anchor nut 601, spacer 602, upper anchor plate 400 and lower anchor plate 500, upper anchor plate 400 and lower anchor plate 500 are annular plates, have two circles of anchor bolt holes, two circles of anchor bolt holes are anchored The center line of the inner and outer diameters of the plate is symmetrically distributed. The lower anchor plate 500 is provided with a support hole for connecting the support of the lower anchor plate, and a fixing hole for connecting the nut to fix the connector 100; The nut 601 and the washer 602 are fixed, and the other end is connected to the lower anchor plate 500 , and is fixed ...

Embodiment 3

[0066] As a typical implementation, this embodiment discloses a method for replacing anchor bolts, which is used for handling when the replaceable anchor bolt assembly embedded in the foundation and installed detects that the anchor bolt is broken, including the following steps:

[0067] 1) Take out the broken upper anchor directly;

[0068] 2) Install the anchor bolt fixing connector 800, insert the broken anchor bolt 830 into the anchor bolt buckle 813 of the inner connecting rod 810 first, and tighten it by rotating the outer locking sleeve 820 after extending into the broken anchor bolt hole. And after a certain pre-tightening force is applied, the broken lower anchor bolt 830 can be fixed;

[0069] 3) Since the anchor nut 601 and the washer 602 of the lower anchor bolt 830 under the lower anchor plate 500 are fixed by the nut fixing connector 100, the anchor bolt fixing connector 800 that has fixed the broken lower anchor bolt 830 is rotated, and the broken lower section ...

Abstract

The invention discloses a connector for anchor replacement, an anchor system and an anchor replacement method, and relates to the field of wind power generators, wherein the connector for anchor replacement includes a nut-fixed connector and an anchor-fixed connection The nut fixing connector is used to connect the nut, the nut fixing connector can also be connected to the anchor plate, the anchor bolt fixing connector is used to connect the anchor bolt, the nut is threaded with the anchor bolt, and the anchor bolt is connected to the anchor plate; The fixing connector is in the shape of a ring, and multiple rings of mounting holes are arranged on the nut fixing connector, and each ring of mounting holes is equidistantly arranged; the mounting holes can cooperate with the nut to fix the nut's axial rotation. The invention adopts a connecting piece which is easy to install and has high reliability, which can meet the requirements for anchor bolt replacement; the invention adopts a safe and easy-to-operate replacement method to realize anchor bolt replacement.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a connecting piece for anchor bolt replacement, an anchor bolt system and an anchor bolt replacement method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The inventors found that at present, the height of the hub of the wind power generating set is more than 90 meters, and the foundation load of the wind turbine is relatively large. Anchor bolt cages are very important to wind turbines, and failure and fracture of one anchor rod will lead to the scrapping of the entire wind turbine, resulting in serious property losses. Improving the strength of the anchor can reduce the failure of the anchor, but there is no 100% guarantee that the anchor will not fail, and it will also greatly increase the cost. Therefore, it is very important to enable the a...
