Description

Technical Field

[0001] This utility model relates to the field of wind turbine generator installation technology, specifically to a tooling for reinforcing the hub pitch control cabinet bracket of a wind turbine generator. Background Technology

[0002] The pitch control unit bracket for wind turbine generators is typically made of 304 stainless steel square tubing. Because the hub bracket is constantly rotating, it is significantly affected by rotational torque. Furthermore, due to issues with the bracket material or manufacturing process, cracks easily appear at the bolt fixing points of the stainless steel bracket over time, affecting its lifespan and potentially leading to breakage if not addressed promptly. There are generally two ways to address this problem: one is to replace the bracket, which is expensive and involves a long reinstallation period. The other is to reinforce the cracked areas of the bracket by inserting a reinforcing spare part into the stainless steel square tubing bracket, extending approximately 20cm to both sides of the original crack. Finally, the stainless steel square tubing of the pitch control unit bracket is secured to the reinforcing spare part with bolts.

[0003] In the second method of reinforcing the wind turbine generator pitch control unit bracket, drilling is required on the original bracket body. Because the original bracket is made of 304 stainless steel square tubing, which is 5mm thick, using a regular electric drill easily leads to misalignment, poor drill bit stability, and significant drilling difficulty. While a magnetic drill can be used, the magnetic base needs to be attracted to a fixed component. Since the pitch control unit bracket is made of stainless steel, the magnetic base of the drill cannot be attracted to the surface of the stainless steel square tubing, making it difficult to effectively fix the drill. Utility Model Content

[0004] To address the shortcomings of existing technologies, a tooling for reinforcing the wind turbine hub pitch control unit bracket is proposed, which solves the problem in the aforementioned background technology that the magnetic base of the magnetic drill cannot be attracted to the surface of the stainless steel pitch control unit bracket, making it difficult to effectively fix the magnetic base drill.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A tooling for reinforcing a wind turbine hub pitch control unit bracket includes a support plate. Fastening components are respectively provided on both sides of the support plate. The support plate is fixed to the pitch control unit bracket by the fastening components. A magnetic drill is attracted to the support plate by a magnetic base, thereby indirectly fixing it to the pitch control unit bracket, so as to facilitate drilling holes in the pitch control unit bracket.

[0007] Furthermore, the fastening assembly includes side plates symmetrically arranged about the support plate, the support plate being snapped onto the surface of the pitch control unit bracket via the two side plates.

[0008] Furthermore, the fastening assembly also includes a fastening bolt that penetrates the side plate. The fastening bolt is threaded to the side plate, and the end of the fastening bolt abuts against the pitch control cabinet bracket to achieve tooling fixation.

[0009] Furthermore, the fastening component is located at one end of the support plate, and the other end of the support plate is provided with a positioning post. The positioning post is inserted into the mounting hole on the pitch control cabinet bracket to achieve tooling positioning.

[0010] Furthermore, a reinforcing member is detachably connected inside the pitch control cabinet bracket. The reinforcing member has a clearance hole corresponding to the mounting hole, and a connection hole for connecting with the pitch control cabinet bracket is also provided on the reinforcing member.

[0011] Furthermore, the support plate has a reserved hole, through which the drill bit of the magnetic base drill passes to drill a reinforcement hole on the pitch control cabinet bracket. The distance between the reserved hole and the positioning post is equal to the distance between the connecting hole and the clearance hole.

[0012] Furthermore, several sets of the connecting holes are provided along the length direction of the reinforcement, and several sets of the corresponding reserved holes are provided along the length direction of the support plate.

[0013] Furthermore, a gasket is provided on the outside of the pitch control cabinet bracket. After the reinforcement component is inserted into the pitch control cabinet bracket so that the connection hole is aligned with the reinforcement hole, bolts are used to pass through the gasket, the pitch control cabinet bracket and the reinforcement component in sequence, and the pitch control cabinet bracket is reinforced by locking with nuts.

[0014] Furthermore, the cross-section of the pitch control cabinet bracket is U-shaped, and the two sides of the reinforcing member are provided with bent edges. The reinforcing member is slidably connected to the inner side of the pitch control cabinet bracket.

[0015] Furthermore, the support plate is made of Q235 carbon steel.

[0016] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0017] In this application, a support plate is installed on a stainless steel pitch control unit bracket to effectively connect the pitch control unit bracket and the tooling. This allows the magnetic base of the magnetic drill to be reliably fixed to the tooling, achieving stable installation of the magnetic drill on the pitch control unit bracket. With the help of the special tooling, the magnetic drill can quickly and accurately drill holes in the pitch control unit bracket, making the operation convenient and effectively solving the problem of difficult drilling for pitch control unit bracket reinforcement.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1 to 7 As shown, a tooling for reinforcing a wind turbine hub pitch control cabinet support includes a support plate 1. Fastening components are respectively provided on both sides of the support plate 1. The support plate 1 is fixed to the pitch control cabinet support 2 through the fastening components. A magnetic drill is attracted to the support plate 1 through a magnetic base, thereby indirectly fixing it to the pitch control cabinet support 2, so as to facilitate drilling holes in the pitch control cabinet support 2.

[0029] With the above setup, a support plate 1 is installed on the stainless steel pitch control cabinet bracket 2, effectively connecting the pitch control cabinet bracket 2 with the tooling. This allows the magnetic base of the magnetic drill to be reliably fixed onto the tooling, achieving stable installation of the magnetic drill on the pitch control cabinet bracket 2. With the help of the special tooling, the magnetic drill can quickly and accurately drill holes in the pitch control cabinet bracket 2, making the operation convenient and effectively solving the problem of difficult drilling for reinforcement of the pitch control cabinet bracket 2.

[0030] Specifically, the pitch control cabinet bracket 2 is set at the bottom of the pitch control cabinet 11 and extends outward along the four corners of the pitch control cabinet 11. The pitch control cabinet 11 is fixedly installed with the support structure through the pitch control cabinet bracket 2. The pitch control cabinet bracket 2 is reinforced by the reinforcement structure to avoid stress concentration at the root and the generation of cracks.

[0031] In the tooling for reinforcing the pitch control cabinet support in this embodiment, the fastening assembly includes side plates 3 symmetrically arranged about the support plate 1, and the support plate 1 is snapped onto the surface of the pitch control cabinet support 2 by the two side plates 3.

[0032] Specifically, the pitch control unit bracket 2 is a square tube structure, the support plate 1 is a rectangular plate structure, and the two side plates 3 are symmetrical about the width of the support plate 1. The support plate 1 is connected to the outside of the square tube by the two side plates 3.

[0033] In the tooling for reinforcing the pitch control cabinet support in this embodiment, the fastening assembly also includes a fastening bolt 4 that penetrates the side plate 3. The fastening bolt 4 is threadedly connected to the side plate 3, and the end of the fastening bolt 4 abuts against the pitch control cabinet support 2 to fix the tooling.

[0034] To increase the connection strength between the tooling and the pitch control cabinet bracket 2, the insertion depth of the fastening bolt 4 into the side plate 3 is adjusted by rotating the fastening bolt 4 until its end is pressed against the side of the pitch control cabinet bracket 2, thereby firmly fixing the tooling to the pitch control cabinet bracket 2 from both sides, improving the stability of the support plate 1, and ensuring the drilling accuracy of the magnetic drill adsorbed on the support plate 1.

[0035] Preferably, the side plate 3 is set perpendicular to the support plate 1 and matches the square tube structure. Each side plate 3 is threaded with two locking bolts 4 to further improve the fixing strength of the tooling.

[0036] In the tooling for reinforcing the pitch control cabinet bracket in this embodiment, the fastening component is located at one end of the support plate 1, and the other end of the support plate 1 is provided with a positioning post 5. The positioning post 5 is inserted into the mounting hole 6 on the pitch control cabinet bracket 2 to achieve tooling positioning.

[0037] Specifically, the mounting holes 6 on the pitch control cabinet bracket 2 are used to fix the pitch control cabinet as a whole onto the wind turbine generator set. When performing reinforcement drilling, the positioning pins 5 are inserted into the mounting holes 6 to further limit the support plate 1. This, together with the fastening components, improves the installation stability of the tooling and facilitates the positioning of the tooling on the pitch control cabinet bracket 2.

[0038] In the tooling for reinforcing the pitch control cabinet support in this embodiment, a reinforcing member 7 is detachably connected inside the pitch control cabinet support 2. The reinforcing member 7 has a clearance hole corresponding to the mounting hole 6, and the reinforcing member 7 is also provided with a connection hole 8 for connecting with the pitch control cabinet support 2.

[0039] The relief hole on the reinforcement 7 ensures that the connection structure can be smoothly inserted into the mounting hole 6, avoiding affecting the overall installation of the pitch control cabinet. The connection hole 8 is set to cooperate with the hole drilled on the pitch control cabinet bracket 2, so that the reinforcement 7 can be fixed on the pitch control cabinet bracket 2 through the connector.

[0040] In the tooling for reinforcing the pitch control cabinet support in this embodiment, the support plate 1 is provided with a reserved hole 9. The drill bit of the magnetic base drill passes through the reserved hole 9 so as to drill a reinforcing hole 10 on the pitch control cabinet support 2. The distance between the reserved hole 9 and the positioning post 5 is equal to the distance between the connecting hole 8 and the clearance hole.

[0041] With the above settings, the reinforcement 7 and the support plate 1 use the mounting hole 6 as a reference point to align the connection hole 8 with the reserved hole 9. The reserved hole 9 is used to position the reinforcement hole 10, ensuring that after the reinforcement 7 is installed on the pitch control cabinet bracket 2, the clearance hole coincides with the mounting hole 6, thus avoiding affecting the installation of the pitch control cabinet.

[0042] In the tooling for reinforcing the pitch control cabinet bracket in this embodiment, the connecting holes 8 are arranged in several groups along the length of the reinforcing member 7, and the corresponding reserved holes 9 are arranged in several groups along the length of the support plate 1.

[0043] By setting multiple sets of connecting holes 8 and reserved holes 9, multiple sets of reinforcing holes 10 can be continuously processed, thereby improving the connection strength of the reinforcing member 7 and enhancing the reinforcement effect.

[0044] Specifically, by rotating the fastening bolts 4 on both sides of the support plate 1, the support plate 1 can rotate slightly around the mounting hole 6, thereby achieving a fine adjustment of the position of the reserved hole 9, so that it is distributed along the extension direction of the pitch cabinet bracket 2, and improving the drilling accuracy.

[0045] In the tooling for reinforcing the pitch control cabinet support in this embodiment, a gasket is provided on the outside of the pitch control cabinet support 2. The reinforcing member 7 is inserted into the pitch control cabinet support 2 so that the connecting hole 8 is aligned with the reinforcing hole 10. Bolts are then used to pass through the gasket, the pitch control cabinet support 2 and the reinforcing member 7 in sequence, and the pitch control cabinet support 2 is reinforced by locking it with a nut.

[0046] Specifically, the reinforcing holes 10 are arranged in pairs, and a long strip shim 12 is used for the same set of reinforcing holes 10. The shim 12 is set to further increase the thickness of the pitch control cabinet bracket 2 and enhance its strength.

[0047] In the tooling for reinforcing the pitch control cabinet support in this embodiment, the pitch control cabinet support 2 has a U-shaped cross-section, and the reinforcing member 7 has bent edges on both sides. The reinforcing member 7 is slidably connected to the inner side of the pitch control cabinet support 2.

[0048] With the above settings, the reinforcement component 7 fits tightly against the inner side of the pitch control cabinet bracket 2, increasing the contact area between the two and improving the reinforcement effect.

[0049] In the tooling for reinforcing the pitch control cabinet bracket in this embodiment, the support plate 1 is made of Q235 carbon steel.

[0050] By using the above-mentioned materials, the support plate 1 is guaranteed to have sufficient strength to support the magnetic drill, and at the same time, it can be attracted by the magnetic base to effectively fix the magnetic drill. It is conceivable that the support plate 1 in this application can also be made of other materials that can be attracted by the magnetic base.
