Description

Technical Field

[0001] The present application relates to the technical field of wind turbine main shaft processing, and in particular to a wind turbine main shaft drilling tool. Background Art

[0002] The wind turbine main shaft, as the heart of a wind turbine, plays a vital role. Its core mission is to transfer the mechanical energy generated by the rotor's rotation to the generator, achieving energy conversion. The quality and performance of the main shaft directly impact the stable operation and power generation efficiency of the entire wind turbine system.

[0003] During the precision machining of wind turbine main shafts, drilling is crucial, especially at the shaft end flange, where a circle of bolt mounting holes must be precisely drilled. This process requires extremely high technical skills, as it affects subsequent bolt fixation and the stability of the entire machine.

[0004] However, traditional drilling methods have several drawbacks. After drilling one hole, the entire wind turbine main shaft typically needs to be hoisted with a crane and adjusted to the next drilling location. This practice not only increases reliance on the crane, reducing production efficiency, but also poses significant safety risks because workers must work next to the suspended main shaft.

[0028] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0029] The embodiment of the present application discloses a wind turbine main shaft drilling tool.

[0030] A wind turbine main shaft drilling tool comprises a placement barrel 1, an adjustment assembly 2, and a support base 3. The placement barrel 1 has an opening at the top for inserting the wind turbine main shaft. The adjustment assembly 2 consists of a conveying portion 21 and a rotating portion 22, responsible for horizontal movement and axial rotation, respectively. The support base 3 is mounted on the placement barrel 1 and supports the flange 5 of the wind turbine main shaft.

[0031] When drilling a hole in the flange 5 of a wind turbine main shaft, the main shaft is placed inside a placement cylinder 1, which then provides initial positioning. A conveyor unit 21 then transports the cylinder 1 and the main shaft to the drilling area. After a hole is drilled, a rotating unit 22 rotates the main shaft flange around the main shaft, facilitating continuous drilling.

[0032] A positioning frame 4 is installed inside the placement tube 1. This frame comprises a positioning seat 41 and a positioning rod 42. The positioning seat 41 is fixed inside the placement tube 1, and the positioning rod 42 is mounted on top of the positioning seat 41. When the wind turbine main shaft is placed inside the placement tube 1, the inner hole of the wind turbine main shaft and the positioning rod 42 are plugged into each other, thereby improving the installation stability of the wind turbine main shaft.

[0033] In order to facilitate observation of the placement of the wind turbine main shaft, a mounting opening 11 is provided at the bottom of the side wall of the placement tube 1, so that the staff can visually check the positioning status of the wind turbine main shaft and improve the correctness of the placement of the wind turbine main shaft.

[0034] At the same time, in order to facilitate the positioning frame 4 to adapt to the different inner hole diameters of the wind turbine main shaft, a positioning groove 411 is provided on the top of the positioning seat 41, a limiting groove 412 is provided on the inner wall of the groove, and a limiting plate 421 is installed at the bottom of the side wall of the positioning rod 42 to achieve sliding fit with the limiting groove 412 of the positioning groove 411.

[0035] When installing the positioning rod 42, a positioning rod 42 of corresponding diameter is selected according to the different inner hole diameters of different wind turbine main shafts. Then, the positioning rod 42 is inserted into the positioning groove 411, and the positioning rod 42 is rotated to make the limiting plate 421 slide inside the limiting groove 412. The limiting plate 421 is limited by the inner wall of the limiting groove 412, thereby improving the adaptability to wind turbine main shafts with different inner hole diameters.

[0036] The support base 3 includes a support ring 31 and a clamping member 32. The support ring 31 is fixed to the outer wall of the placement tube 1 and is used to support the flange 5 of the wind turbine main shaft. The clamping member 32 consists of a clamping frame 321 and a clamping rod 322. The clamping rod 322 extends through the clamping frame 321 and is threaded to one end. The other end is used to firmly clamp the flange 5 of the wind turbine main shaft.

[0037] One end of the clamping rod 322 close to the wind turbine main shaft is tilted downward, and a frustum is provided at the end of the clamping rod 322 , and the tapered side of the frustum is parallel to the flange 5 of the wind turbine main shaft.

[0038] After the flange 5 of the wind turbine main shaft is placed on the support ring 31, the clamping rod 322 is rotated, and the clamping rod 322 drives the table to move toward the flange 5 of the wind turbine main shaft, and the table presses the flange 5 of the wind turbine main shaft against the support ring 31, thereby improving the placement stability of the wind turbine main shaft and facilitating the synchronous rotation of the placement tube 1 and the wind turbine main shaft.

[0039] At the same time, the support ring 31 supports the flange 5 of the wind turbine main shaft, reducing the possibility of deformation of the flange 5 of the wind turbine main shaft during the drilling process. At the same time, a number of protrusions 311 are designed on the top of the support ring 31. These protrusions 311 interfere with the flange 5 of the wind turbine main shaft, and the flange 5 of the wind turbine main shaft is supported by the protrusions 311. In the embodiment of the present application, the protrusions 311 are all hemispherically arranged, and the flange 5 of the wind turbine main shaft and the protrusions 311 are in point contact.

[0040] The flange 5 of the wind turbine main shaft and the protrusion 311 have a smaller contact area, which makes it easier to clean the protrusion 311, improves the convenience of cleaning the protrusion 311, and further reduces the impact of dust attached to the protrusion 311 on the flange 5 of the wind turbine main shaft.

[0041] The conveying section 21 consists of a guide rail 211 and a support platform 212, which can slide along the guide rail 211. The rotating section 22 consists of a slewing support 221 and a rotary drive unit 222. The slewing support 221 is mounted on top of the support platform 212, and the placement cylinder 1 is fixed to the slewing support 221. The rotary drive unit 222 realizes the rotation of the wind turbine main shaft.

[0042] When transporting the placement tube 1, the support platform 212 drives the placement tube 1 to move to the drilling area to drill holes in the flange 5 of the wind turbine main shaft. Then, the rotary drive unit 222 drives the slewing support 221 to rotate, and the slewing support 221 drives the placement tube 1 and the wind turbine main shaft inside the placement tube 1 to rotate, so as to facilitate drilling multiple holes in the flange 5 of the wind turbine main shaft, thereby improving the convenience of drilling holes in the flange of the wind turbine main shaft.

[0043] The implementation principle of a wind turbine main shaft drilling tool in the embodiment of the present application is as follows:

[0044] When placing the wind turbine main shaft, select a positioning rod 42 with a corresponding diameter according to the different inner hole diameters of different wind turbine main shafts, and then insert the positioning rod 42 into the positioning groove 411, and rotate the positioning rod 42 to make the limiting plate 421 slide inside the limiting groove 412, and limit the limiting plate 421 through the inner wall of the limiting groove 412.

[0045] After the flange 5 of the wind turbine main shaft is placed on the support ring 31 , the pressing rod 322 is rotated, and the pressing rod 322 drives the round table to move toward the flange 5 of the wind turbine main shaft, and the round table presses the flange 5 of the wind turbine main shaft against the support ring 31 .

[0046] When drilling a hole in the flange 5 of the wind turbine main shaft, the support platform 212 drives the placement tube 1 to move to the drilling area to drill a hole in the flange 5 of the wind turbine main shaft. Then, the rotary drive unit 222 drives the slewing support 221 to rotate, and the slewing support 221 drives the placement tube 1 and the wind turbine main shaft inside the placement tube 1 to rotate, so as to facilitate continuous drilling.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
