Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind power generation technology, specifically to a tooling for centering a generator pair in a wind turbine. Background Technology
[0002] Wind turbines capture wind energy through their impellers, which then drive a generator via a gearbox and coupling, converting mechanical energy into electrical energy. If the central axes of the gearbox and generator are not aligned, long-term operation of the wind turbine will lead to increased vibration in the generator and gearbox, increased wear on bearings and gears, and loss of operating energy. This can also easily cause various malfunctions. Therefore, alignment checks and adjustments are necessary for wind turbines.
[0003] When performing alignment checks and adjustments on a wind turbine, workers need to loosen the anchor bolts that secure the generator. Because the generator of a wind turbine is higher in the front and lower in the back, gravity can cause the generator to slide backward, resulting in a backward slippage phenomenon. Utility Model Content
[0004] This invention provides a tooling for aligning wind turbine generators, which solves the problem that gravity causes the generator to slide backward during the current alignment detection and adjustment of wind turbine generators, resulting in the generator slipping backward.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A tooling for centering a generator pair in a wind turbine includes a base, a support arm, and a fixing clamp. One end of the base has a hook, and the other end of the base is provided with a support arm. A through hole is provided on the support arm, and one end of the fixing clamp passes through the through hole and is mounted on the support arm.
[0007] The beneficial effects of this invention are as follows: By setting hooks on the base, the fixture is stably hung on the bottom crossbeam of the generator. The fixing position of the clamp is then adjusted according to the site conditions, ensuring that one end of the clamp abuts against one side of the generator, preventing it from sliding backward and avoiding backward slippage due to gravity. The fixture features an adjustable design, allowing for flexible adjustments based on site conditions, ensuring the generator remains stable under various circumstances. This device is simple in design and easy to use; workers can quickly complete the installation without requiring numerous tools or complex steps, reducing installation time and improving the generator's alignment efficiency and stability.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, one end face of the base is a flat surface, and the other end face is a slope. The height of one end of the base is less than the height of the other end. The hook is set at the end with the lower height, and the support arm is set at the end with the higher height. The support arm is fixed perpendicularly to one side of the base.
[0010] The beneficial effect of adopting the above-described further solution is that one end face of the base is a plane, which can be aligned with the generator's crossbeam, allowing the device to be stably hung on the generator's bottom crossbeam. Simultaneously, the end face with the hook is lower than the end face where the support arm is located, ensuring that the fixing clamps on the support arm move without obstruction.
[0011] Furthermore, the hook is inverted at the flat end of the base.
[0012] The advantage of adopting the above-mentioned further solution is that one end face of the base is a plane, which can be faced towards the crossbeam of the generator, so that the device can be stably hung on the bottom crossbeam of the generator.
[0013] Furthermore, the support arm is fixedly welded to the base.
[0014] The advantages of adopting the above-mentioned further solution are that by fixing the support arm to the base and making it perpendicular to the base, the fixing clamps on the support arm are aligned with the base on the same parallel plane, facilitating the adjustment of the fixing clamps' position. This allows workers to complete the installation quickly, reduces installation time, and improves the generator's alignment efficiency and stability.
[0015] Furthermore, the top of the support arm is higher than the end face of the base, and the through hole is located where the support arm is higher than the end face of the base.
[0016] The advantages of adopting the above-mentioned further solution are that the height of the support arm is higher than the height of the base end face, which means that the fixing clamps installed on the support arm are also higher than the height of the base end face and are on the same parallel plane as the base, facilitating the adjustment of the fixing position of the fixing clamps. This allows workers to complete the installation quickly, reduces installation time, and improves the alignment efficiency and stability of the generator.
[0017] Furthermore, the inner wall of the through hole has internal threads.
[0018] The advantage of adopting the above-mentioned further solution is that the inner wall of the through hole has internal threads, which facilitates the adjustment of the fixing fixture by rotating the through hole.
[0019] Furthermore, the fixing fixture is a threaded rod, which is screwed into the through hole.
[0020] The beneficial effect of adopting the above-mentioned further solution is that the threaded rod is screwed into the through hole, so that the fixing fixture can be rotated and adjusted in the through hole to fix its position.
[0021] Furthermore, the fixing clamp is movable and mounted on the support arm.
[0022] The advantages of adopting the above-mentioned further solution are that the fixing clamp is movable and mounted on the support arm, and the support arm uses the fixing clamp to keep the fixing clamp and the base on the same parallel plane, which facilitates the adjustment of the fixing clamp's fixed position. This allows workers to complete the installation quickly, reduces installation time, and improves the generator's alignment efficiency and stability.
[0023] Furthermore, the base is 2cm thick, the length from the bottom of the hook groove to the side of the support arm is 53cm, and the base length is 61cm.
[0024] The advantage of adopting the above-mentioned further solution is that the specifications of the base are set according to the position of the generator to be fixed, making the device more stable.
[0025] Furthermore, the height of the support arm is 21cm, and the distance from the highest edge of the through hole to the bottom of the support arm is 18cm.
[0026] The advantage of adopting the above-mentioned further solution is that the specifications of the support arm are set according to the position of the generator to be fixed, making the device more stable. Attached Figure Description

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0030] Example 1
[0031] like Figure 1 As shown, a tooling for centering a wind turbine generator set includes a base 1, a support arm 2, and a fixing clamp 3. One end of the base 1 has a hook 11, and the other end of the base 1 is provided with a support arm 2. A through hole 21 is provided on the support arm 2, and one end of the fixing clamp 3 passes through the through hole 21 and is provided on the support arm 2.
[0032] Specifically, by setting a hook 11 on the base 1, the tooling is stably hung on the bottom crossbeam of the generator using the hook 11. Then, the fixing position of the fixing clamp 3 is adjusted according to the site conditions so that one end of the fixing clamp 3 abuts against one side of the generator to prevent the generator from sliding backward and avoid the generator from slipping backward due to gravity.
[0033] like Figure 1 As shown, one end face of the base 1 is a plane and the other end face is an inclined plane. The height of one end of the base 1 is less than the height of the other end. The hook 11 is set at the end with the smaller height, and the support arm 2 is set at the end with the larger height. The support arm 2 is fixed perpendicularly to one side of the base 1.
[0034] Specifically, one end face of the base 1 is a flat surface, which can be aligned with the generator's crossbeam, allowing the device to be stably hung on the generator's bottom crossbeam. Simultaneously, the end face with the hook 11 is lower than the end face where the support arm 2 is located, ensuring that the fixing clamp 3 on the support arm 2 moves without obstruction.
[0035] like Figure 1 As shown, the hook 11 is inverted at one end of the base 1 that has a flat surface.
[0036] Specifically, one end face of the base 1 is a flat surface, which can be oriented towards the crossbeam of the generator, so that the device can be stably hung on the bottom crossbeam of the generator.
[0037] like Figure 1 As shown, the support arm 2 is fixedly welded to the base 1.
[0038] Specifically, the support arm 2 is fixedly welded to the base 1, perpendicular to the base 1, so that the fixing clamp 3 on the support arm 2 is on the same parallel plane as the base 1, facilitating the adjustment of the fixing position of the fixing clamp 3. This allows workers to complete the installation quickly, reducing installation time and improving the alignment efficiency and stability of the generator.
[0039] like Figure 1 As shown, the top of the support arm 2 is higher than the end face of the base 1, and the through hole 21 is located at the position where the support arm 2 is higher than the end face of the base 1.
[0040] Specifically, the height of the support arm 2 is higher than the height of the end face of the base 1, so that the fixing clamp 3 set on the support arm 2 is higher than the end face of the base 1 and is on the same parallel plane as the base 1, which facilitates the adjustment of the fixing position of the fixing clamp 3. This allows the staff to complete the installation quickly, reduces installation time, and improves the alignment efficiency and stability of the generator.
[0041] like Figure 1 As shown, the inner wall of the through hole 21 has internal threads.
[0042] Specifically, the inner wall of the through hole 21 has internal threads, which facilitates the adjustment of the fixing clamp 3 by rotating it in the through hole 21.
[0043] like Figure 1 As shown, the fixing fixture 3 is a threaded rod, which is screwed into the through hole 21.
[0044] Specifically, the threaded rod is screwed into the through hole 21, so that the fixing clamp 3 can rotate and adjust its fixed position within the through hole 21.
[0045] like Figure 1 As shown, the fixing clamp 3 is movably mounted on the support arm 2.
[0046] Specifically, the fixing clamp 3 is movably mounted on the support arm 2, using the support arm 2 to align the fixing clamp 3 and the base 1 on the same parallel plane, facilitating adjustment of the fixing position of the fixing clamp 3. This allows workers to quickly complete the installation, reducing installation time and improving the generator's alignment efficiency and stability.
[0047] like Figure 1 As shown, the thickness of the base 1 is 2cm, the length from the bottom of the hook groove of the hook 11 to the side of the support arm 2 is 53cm, and the length of the base 1 is 61cm.
[0048] Specifically, the specifications of base 1 are set according to the required fixed position of the generator to make the device more stable.
[0049] like Figure 1 As shown, the height of the support arm 2 is 21cm, and the distance from the highest edge of the through hole 21 to the bottom of the support arm 2 is 18cm.
[0050] Specifically, the specifications of support arm 2 are set according to the position of the generator to make the device more stable.
[0051] The beneficial effects of this embodiment are as follows: The tooling is stably hung on the bottom crossbeam of the generator using hook 11. The fixing position of the clamp 3 is then adjusted according to the site conditions, ensuring that one end of the clamp 3 abuts against one side of the generator, preventing it from sliding backward and avoiding backward slippage due to gravity. The tooling features an adjustable design, allowing for flexible adjustment based on site conditions, ensuring the generator remains stable under various conditions. This device is simple in design and easy to use; workers can quickly complete the installation without requiring numerous tools or complex steps, reducing installation time and improving the generator's alignment efficiency and stability.
[0052] The working process of this embodiment is as follows: hang the hook 11 on the bottom crossbeam of the generator, and then turn the fixing clamp 3 according to the site conditions to adjust the fixing position of the fixing clamp 3 on the generator until one end of the fixing clamp 3 abuts against one side of the generator to fix the generator so that the generator does not slide.
