Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine auxiliary equipment, in particular to a deep hole broken wire extraction device for a wind turbine set. Background Art

[0002] Wind turbine pitch bearing bolts are used to connect the wind turbine's pitch bearings, providing both securement and connection. In most wind turbines, these bolts often break due to insufficient torque, either due to quality issues or other problems. After the bolts break, they can leave residual broken wire embedded in the deep hole.

[0003] After the bolt is broken, it needs to be removed from the deep hole. The existing broken wire extraction device inserts a drill bit into the hollow tube, and uses a hexagonal screw to tighten the drill bit at the drill bit insertion position in the hollow tube. However, due to the small tightening torque of the bolt, the drill bit is likely to slip during the drilling process. Secondly, a four-sided pointed steel drill is used to knock, insert and twist the broken wire after drilling. This process is very likely to cause the steel drill to fall off from the hole, and this process needs to be repeated continuously, so it is difficult to remove the broken wire from the deep hole.

[0004] Therefore, how to easily extract the broken wires in the deep hole has become an urgent problem to be solved in this field. Utility Model Content

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] In the present invention, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0042] like Figure 1 1 is a schematic diagram of the structure of a deep hole broken wire extraction device for a wind turbine generator set according to an embodiment of the present invention. The deep hole broken wire extraction device for a wind turbine generator set includes: a triangular chuck 11, an extension rod 12, a fastening component 13 and a clamping component 14.

[0043] One end of the extension rod 12 is provided with a thread to form a threaded end.

[0044] The fastening component 13 and the triangular chuck 11 are sequentially rotatably sleeved on the extension rod 12 through the threaded ends, and the fastening component 13 is located on the inner side of the triangular chuck 11 .

[0045] The fastening component 13 is used to tighten the triangular chuck 11 in the opposite direction after the triangular chuck 11 is tightened.

[0046] It is understandable that after the triangular chuck 11 is tightened around the extension rod 12 , the fastening component 13 tightens the triangular chuck 11 in the opposite direction to prevent the triangular chuck 11 from loosening during the process of removing the broken wire.

[0047] Specifically, the fastening component 13 is an anti-loosening locking nut.

[0048] The clamping component 14 is mounted on the triangular chuck 11 .

[0049] The clamping component 14 is used to extract broken wires from deep holes of wind turbines.

[0050] Further, see Figure 2 The deep hole broken wire extraction device of the wind turbine generator set also includes: at least two limiting sleeves 21 and a limiting guide extension tube 22.

[0051] The limiting guide extension tube 22 installed between the first limiting sleeve 21 and the second limiting sleeve 21 is sleeved on the extension rod 12 .

[0052] Among them, the limiting guide extension tube 22 is used to support the extension rod 12 so that the axis of the extension rod 12 is aligned with the axis of other components; the limiting sleeve 21 is used to set the rotation center of the extension rod 12 at the middle position of the deep hole.

[0053] It is understandable that the limiting sleeve 21 is inserted into the deep hole of the wind turbine together with the extension rod 12 , and the limiting sleeve 21 ensures that the rotation center of the extension rod 12 is located in the middle of the deep hole of the wind turbine.

[0054] It should be noted that due to the deep hole in the wind turbine, a limiting guide extension tube 22 is inserted between the two limiting sleeves 21. By using the limiting guide extension tube 22, the extension rod 12 can be effectively supported and maintained in the correct position, thereby ensuring that its axis is aligned with the axes of other components. This alignment helps avoid deviation or instability, improving the accuracy and reliability of the system.

[0055] Specifically, the inner diameter of the limiting sleeve 21 is larger than the diameter of the extension rod 12 , and the outer diameter of the limiting sleeve 21 is smaller than the diameter of the deep hole.

[0056] Optionally, the inner diameter of the limiting sleeve 21 needs to be 2 mm to 3 mm larger than the diameter of the extension rod 12 so that the extension rod 12 can rotate in the limiting sleeve 21 .

[0057] It is understandable that the outer diameter of the limiting sleeve 21 is slightly smaller than the diameter of the deep hole of the wind turbine generator set, so that the limiting sleeve 21 can be inserted into the deep hole of the wind turbine generator set along with the extension rod 12 .

[0058] Specifically, the length of the extension rod 12 ranges from 40 cm to 20 cm and / or the length of the position-limiting guide extension tube 22 ranges from 25 cm to 35 cm.

[0059] The first limiting sleeve 21 is disposed on the inner side of the fastening component 13 .

[0060] Further, see Figure 3 The clamping component 14 includes: a clamping drill bit 31.

[0061] The drill bit 31 is mounted on the triangular chuck 11 .

[0062] The clamping drill bit 31 is used to drill the tail of the broken wire in the deep hole of the wind turbine.

[0063] It is understandable that by drilling the tail of the broken wire in the deep hole of the wind turbine generator set with the clamping drill bit 31, the extraction tool can enter the deep hole more easily, and the interference with the surrounding structures is reduced, thereby improving the success rate of extraction.

[0064] It should be noted that the tail of the broken wire in the deep hole of the wind turbine is drilled by clamping the drill bit 31. The drilling position is in the middle of the tail of the broken wire. The limiting sleeve 21 can be used to position the drilling position in the middle to facilitate subsequent extraction of the broken wire.

[0065] Further, see Figure 4 The deep hole broken wire extraction device of the wind turbine generator set also includes: a conversion sleeve 41 and a rotating hand wheel 42.

[0066] The other end of the extension rod 12 is a polygonal end, which is provided with a thread.

[0067] The conversion sleeve 41 is rotatably sleeved on the extension rod 12 through the polygonal end, and the rotating hand wheel 42 is installed on the conversion sleeve 41 .

[0068] The conversion sleeve 41 is used to connect the rotating hand wheel 42 and the extension rod 12, and the rotating hand wheel 42 is used to apply a rotational torque.

[0069] Optionally, the polygonal end of the extension rod 12 includes but is not limited to a hexagonal end. Figure 5 shown.

[0070] It can be understood that since one end of the conversion sleeve 41 is a polygonal end and the other end is a square end, the conversion sleeve 41 is connected to the extension rod 12 through the polygonal end, and the rotating handwheel 42 is connected to the conversion sleeve 41 through the square end.

[0071] Further, see Figure 6 The clamping component 14 includes: a clamping broken wire extractor 61.

[0072] The broken wire clamping and extracting device 61 is installed on the triangular chuck 11 .

[0073] The broken wire clamping extractor 61 is used to extract broken wires from deep holes of wind turbines.

[0074] It should be noted that the clamping broken wire extractor 61 matches the aperture of the triangular chuck 11. During the specific operation, the clamping broken wire extractor 61 is inserted into the hole drilled by the clamping drill bit 31 and kept vertical. Then, a hammer is used to lightly hit the tail end of the rotating handwheel 42 to knock on the platform so that the reverse thread of the clamping broken wire extractor 61 is fully tightened with the broken wire hole. Then, the rotating handwheel 42 is used to evenly apply the torque to slowly reverse and remove the broken wire.

[0075] Further, see Figure 7 The clamping component is a clamping strong magnetic block 71.

[0076] The clamping strong magnetic block 71 is installed on the triangular chuck 11 .

[0077] The clamping strong magnetic block 71 is used to absorb broken wires and iron filings from deep holes of the wind turbine.

[0078] It is understandable that a lot of iron filings will be generated during the drilling process, which need to be cleaned after the drilling is completed. Once the iron filings are not cleaned thoroughly or there are iron filings stuck in the threads, when the broken wire extractor 61 is clamped to extract the broken wire, it will get stuck and the broken wire will be difficult to remove. Therefore, the strong magnetic block 71 must be used to clamp the tail of the broken wire after drilling to thoroughly and carefully clean it.

[0079] It should be noted that after the broken wire is completely tightened by the clamping broken wire remover 61, it is difficult to clamp the broken wire because it is located in a deep hole. The broken wire has a large weight and is difficult to remove by conventional methods. The use of the clamping strong magnetic block 71 in combination with the triangular chuck 11 and the extension rod 12 can easily remove the broken wire in the deep hole.

[0080] Combine Figure 2 or Figure 7 The content shown also includes: the other end of the extension rod is a polygonal end, and the polygonal end is provided with a thread.

[0081] The hand electric drill is rotatably sleeved on the extension rod 12 through the polygonal end.

[0082] It is understandable that the drilling operation is performed by installing an electric hand drill and inserting the electric hand drill into a deep hole of the wind turbine.

[0083] Combine Figure 1 For the contents shown, see Figure 8 As can be seen, extracting broken wires from deep holes in wind turbines requires multiple components. These components are assembled to create a device for extracting broken wires from deep holes in wind turbines. These components include a triangular chuck 11, an extension rod 12, a fastening component 13, a limiting sleeve 21, a limiting guide extension tube 22, a conversion sleeve 41, and a rotating handwheel 42.

[0084] In summary, the processes of drilling, unscrewing and sucking can be completed by the clamping component. During the drilling process, the fastening component is used to tighten the clamping component in the opposite direction to prevent the triangular chuck from loosening. During the unscrewing process, the reverse thread of the clamping component is fully tightened with the broken wire hole. During the suction process, the clamping component is used in combination with the triangular chuck and the extension rod to easily remove the broken wire in the deep hole.
