Description

Technical Field

[0001] The present invention belongs to the technical field of equipment tooling, and in particular relates to a bolt removal tooling. Background Art

[0002] With the popularity of green energy, wind turbines have also attracted people's attention. A large number of connecting bolts are used in the various connecting parts of wind turbines. Connecting bolts are often used in important connecting structures of wind turbines. For example, high-strength bolts are used to connect the wind turbine blades and the wheel rollers. With the large-scale and harsh working environment, the working strength of the connecting bolts increases, and connecting bolt breakage failures occur from time to time. Once the connection failure problem occurs at the root of the blade, the blade will separate from the hub, and the pitch action will not be able to proceed normally. At this time, the generator cannot work normally, and even more serious safety accidents may occur. Therefore, it is very necessary to promptly detect the breakage of the pitch connection bolts, remove the broken bolts as soon as possible, and install new bolts for the safe and normal operation of wind turbines.

The longitudinal connecting plate 1 is provided in two, and the first ends of the two longitudinal connecting plates 1 are used to be respectively connected to the components where the bolts are located, and the first end and the second end of the transverse connecting plate 2 are respectively connected to the second ends of the two longitudinal connecting plates 1, and the second end of at least one of the two longitudinal connecting plates 1 is rotatably connected to the transverse connecting plate 2 so that the first ends of the two longitudinal connecting plates 1 can swing relative to each other, and the support seat is connected to the transverse connecting plate 2 for supporting the bolt removal drill body 5.

[0037] The bolt removal tool provided by the present invention can be used for removing broken bolts. It is connected to the component where the bolt is located through the longitudinal connecting plate 1, so that the bolt removal drill body 5 can be stably connected to the component where the bolt is located, thereby facilitating the removal of the bolt.

[0038] In the present invention, the second end of at least one of the two longitudinal connecting plates 1 is rotatably connected to the transverse connecting plate 2, so that the angle between the longitudinal connecting plate 1 and the transverse connecting plate 2 is adjustable, so that the distance between the first ends of the two longitudinal connecting plates 1 is adjustable, so that the bolt removal tool can adapt to the components where different bolts are located, thereby improving the versatility of the bolt removal tool.

[0039] For the convenience of description, the bolt removal tool is particularly suitable for a wind turbine generator set, which may be an onshore wind turbine generator set or an offshore wind turbine generator set, but is not limited thereto. Optionally, this embodiment is described by taking the component where the bolt is located as a variable pitch bearing 6 of a wind turbine generator set as an example, but is not limited thereto.

[0040] Continuing to refer to the drawings, this embodiment is described by taking the example that the second ends of the two longitudinal connecting plates 1 are both rotatably connected to the transverse connecting plate 2, but the present invention is not limited thereto.

[0041] Continue to refer to Figure 1 and Figure 2 , the second end of the longitudinal connecting plate 1 is provided with a first connecting hole 12, and the transverse connecting plate 2 is provided with a second connecting hole, and the first fastener 71 can pass through the first connecting hole 12 and the second connecting hole to connect the longitudinal connecting plate 1 to the transverse connecting plate 2, wherein at least one of the first connecting hole 12 and the second connecting hole is a waist-shaped hole. In this embodiment, the longitudinal connecting plate 1 includes a longitudinal connecting plate body 11, and the first connecting hole 12 is provided at the second end of the longitudinal connecting plate body 11 and is provided through both sides of the longitudinal connecting plate body 11, but is not limited thereto.

[0042] In this embodiment, by having at least one of the first connecting hole 12 and the second connecting hole be a waist-shaped hole, it is convenient to adjust the position and angle of the longitudinal connecting plate 1 relative to the transverse connecting plate 2, so that the bolt removal tool can adapt to the components where different bolts are located, further improving the versatility of the bolt removal tool.

[0043] As an example, continue to refer to Figure 1 and Figure 2 In this embodiment, the first connecting hole 12 is a long hole, and the second connecting hole is a round hole matching the first fastener 71. By setting the first fastener 71 at different positions in the first connecting hole 12, the position and angle of the longitudinal connecting plate 1 relative to the transverse connecting plate 2 can be adjusted, but it is not limited to this.

[0044] In order to improve the connection reliability between the longitudinal connecting plate 1 and the transverse connecting plate 2 and prevent the longitudinal connecting plate 1 from accidentally rotating relative to the transverse connecting plate 2, a second fastener 72 connecting the longitudinal connecting plate 1 and the transverse connecting plate 2 is further provided between the first connecting hole 12 and the first end of the longitudinal connecting plate 1. The two ends of the longitudinal connecting plate 1 can rotate relative to the transverse connecting plate 2 with the second fastener 72 as the rotation axis.

[0059] Reference Figure 1 and Figure 3 Specifically, a fifth connecting hole (not shown) is provided on the transverse adjustment plate 3, and a sixth connecting hole 42 is provided on the longitudinal adjustment plate 4. The fourth fastener 74 passes through the fifth connecting hole and the sixth connecting hole 42 to connect the transverse adjustment plate 3 and the longitudinal adjustment plate 4, wherein at least one of the fifth connecting hole and the sixth connecting hole 42 is a long strip hole and extends along the second direction.

[0060] In this embodiment, the longitudinal adjustment plate 4 includes a longitudinal adjustment plate body 41, and the sixth connection hole 42 is provided on the longitudinal adjustment plate body 41 and is provided on both sides of the longitudinal adjustment plate body 41, but the invention is not limited thereto. Further, there are two sixth connection holes 42, and the two sixth connection holes 42 are spaced apart and parallel to each other along the first direction, and such a configuration avoids accidental rotation of the longitudinal adjustment plate 4 and the transverse adjustment plate 3, thereby improving the reliability of the bolt removal tool.

[0061] In this embodiment, the sixth connecting hole 42 is a long hole, and the fifth connecting hole is a round hole matching the fourth fastener 74. By adjusting the position of the fourth fastener 74 in the sixth connecting hole 42, the relative positions of the longitudinal adjustment plate 4 and the transverse adjustment plate 3 can be adjusted.

[0062] In this embodiment, the longitudinal adjustment plate 4 and the transverse adjustment plate 3 are connected by a plurality of fourth fasteners 74 to further improve the connection reliability of the bolt removal tool. In this embodiment, the bolt removal tool including four fourth fasteners 74 is used as an example for description.

[0063] As required, the fifth connecting hole and the sixth connecting hole 42 are both long holes extending along the second direction. Such a configuration increases the moving stroke of the transverse adjustment plate 3 relative to the longitudinal adjustment plate 4, further improving the versatility of the bolt removal tooling.

[0064] Continue to refer to Figure 1 and Figure 3 The longitudinal adjustment plate 4 also includes a longitudinal adjustment plate body 41 and a pair of second guide portions 43 protruding from the longitudinal adjustment plate body 41 toward the transverse adjustment plate 3. The pair of second guide portions 43 are spaced apart along the first direction and extend along the second direction.

This arrangement enables the bolt removal tool to correspond to the position where the broken bolt is located, further improving the versatility of the bolt removal tool. Furthermore, by arranging the bolt removal tool at the position corresponding to the broken bolt, during the use of the bolt removal drill body 5, the force on the transverse connecting plate 2 is balanced, thereby further improving the reliability of the bolt removal tool.
