[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] The following description, with reference to the accompanying drawings, describes a leveling wrench 100 for an anchor plate on a wind power generation foundation according to an embodiment of the present invention.
[0020] Reference Figures 1-3 The leveling wrench 100 for the anchor plate on the wind power generation foundation according to the present utility model includes: a wrench body 1, a pointer 2 and a leveling scale 3. The wrench body 1 includes a wrench head 11 and a handle 12. The wrench head 11 is connected to one end of the handle 12 in the length direction. The pointer 2 is connected to the part of the handle 12 away from the wrench head 11. The extension direction of the pointer 2 is parallel to the thickness direction of the handle 12, and the end of the pointer 2 away from the handle 12 is provided with a fingertip 21, which has a sharp corner; for example, the sharp corner can be a triangular structure or an arrow-shaped structure.
[0021] The leveling scale 3 includes a scale plate 31 and a fixing member 32. The scale plate 31 has an arc-shaped through hole 311. The center of the arc-shaped through hole 311 coincides with the rotation center of the wrench head 11. A scale 312 is provided on the surface of the scale plate 31 facing away from the wrench body 1. The fixing member 32 is connected to both ends of the scale plate 31 in the extension direction. The fixing member 32 fixes the scale plate 31 relative to the anchor plate on the wind power generation foundation. The pointer 2 is inserted into the arc-shaped through hole 311 and is adapted to slide along the extension direction of the arc-shaped through hole 311; wherein, the tip of the fingertip 21 extends out of the arc-shaped through hole 311 and the tip of the fingertip 21 faces the scale 312.
[0022] When leveling the anchor plate on the wind power generation foundation, the wrench head 11 can be used to hold the nut to be adjusted, and the fixing part 32 can be connected and fixed to the anchor plate on the wind power generation foundation. Then, the wrench head 11 can be rotated by rotating the handle, and the nut can be rotated. When the pointer 2 points to the preset reading, the rotation of the wrench body 1 can be stopped to complete the axial adjustment of the nut.
[0023] Since the center of the arc-shaped through hole 311 coincides with the rotation center of the wrench head 11, when the wrench body 1 rotates, the rotation center of the pointer 2 also coincides with the center of the arc-shaped through hole 311. Therefore, the pointer 2 can slide smoothly in the arc-shaped through hole 311 without causing the scale plate 31 to move, which can effectively ensure the detection accuracy.
[0024] For example, the scale dial 31 can be laser-etched with 60° graduations. Specifically, the scale dial 31 can also have a pitch quick reference table: engraved on the surface of the handle 12, listing the "rise height per 1° rotation" for commonly used nut specifications (M30 / M36 / M42, etc.) (Example: M36 nut P=4mm→1°=0.0111mm, that is, when using the leveling wrench 100 of this utility model to adjust a nut of specification M36 with a pitch P of 4mm, when the pointer 2 rotates by 1°, the corresponding rise or fall height of the nut is 0.0111mm). Its specific operation method is as follows: ① Fix the wrench to the upper anchor plate and adjust the dial so that pointer 2 is aligned with "0" → ② Consult the pitch quick reference table according to the nut specifications → ③ Rotate the wrench until pointer 2 points to the target angle θ → ④ Tighten the nut. At this time, the height change ΔH = θ × (P / 360°).
[0025] Thus, the leveling wrench 100 of this invention enables precise quantitative fine-tuning in the field of high-torque wind power wrenches. This allows operators to accurately level the anchor plates on wind turbine foundations using the leveling wrench 100. Furthermore, the device requires no electricity, making it highly practical for engineering applications. In addition, its overall structure is relatively simple, and its all-mechanical construction is resistant to oil and impact, making it highly adaptable.
[0026] According to the leveling wrench 100 of this utility model, by setting the center of the scale plate 31 with the scale 312 to coincide with the rotation center of the wrench head 11, and setting the pointer 2 of the upper scale 312 on the handle 12, when the operator rotates the wrench body 1, the rotation angle of the nut can be judged by the change of the reading of the pointer 2, thereby determining the axial movement distance of the nut. This allows the operator to fine-tune the rotation angle of the nut by the scale 312, realizing precise quantitative fine-tuning in the field of wind power high torque wrenches. This enables the anchor plate on the wind power generation foundation to be leveled more accurately, and it does not require electrical equipment, making it highly practical for engineering.
[0027] Reference Figures 1-3 According to some embodiments of the present invention, the wrench body 1 further includes a first steering handle 13, which is located on the side of the handle 12 near the leveling wrench 100 and is connected to the end of the handle 12 away from the wrench head 11. The extension direction of the first steering handle 13 is parallel to the thickness direction of the handle 12.
[0028] Since the concrete at the bottom of the anchor plate on the wind power generation foundation has already solidified when using the leveling wrench 100 of this utility model, the operator needs to operate the leveling wrench 100 of this utility model from the top. Therefore, the above-mentioned first steering handle 13 is provided so that the end of the first steering handle 13 can extend upwards to the anchor plate on the wind power generation foundation, making it easier for the operator to hold and drive the nut to rotate through the first steering handle 13.
[0029] Reference Figures 1-3 According to some other embodiments of the present invention, the wrench body 1 further includes a second steering handle, which is located on the side of the handle 12 near the leveling wrench 100 and connected to the end of the handle 12 away from the wrench head 11. The second steering handle extends in a direction away from the leveling scale 3.
[0030] Since the concrete at the bottom of the anchor plate on the wind power generation foundation has already solidified when using the leveling wrench 100 of this utility model, the operator needs to operate the leveling wrench 100 of this utility model from the top. Therefore, the above-mentioned second steering handle is provided so that the end of the second steering handle can extend upwards to the anchor plate on the wind power generation foundation, making it easier for the operator to hold and drive the nut to rotate through the second steering handle.
[0031] Reference Figures 1-3 In some embodiments of this utility model, the fastener 32 includes a first clamping plate 321 and a first fastener. There are two first clamping plates 321, and the two first clamping plates 321 are spaced apart along the thickness direction of the handle 12. The two first clamping plates 321 define a space for accommodating the anchor plate on the wind power generation foundation. The first fastener is connected between the two first clamping plates 321 and is used to drive the two first clamping plates 321 to move towards each other to clamp the anchor plate on the wind power generation foundation.
[0032] This allows the fixed connector 32 to be reliably connected to the anchor plate on the wind power generation foundation by clamping from both above and below, ensuring that the scale plate 31 is reliably positioned relative to the anchor plate on the wind power generation foundation, preventing the scale plate 31 from shaking and causing reading errors, and improving the reliability of the leveling wrench 100.
[0033] Reference Figures 1-3 In some specific embodiments of this utility model, the first clamping plate 321 is provided with a first fastening hole 3211. When the leveling ruler 3 is fixed to the anchor plate on the wind power generation foundation, the first fastening hole 3211 is located on the radial outer side of the anchor plate on the wind power generation foundation. The first fastener includes a bolt and a nut. The bolt thread passes through the two first fastening holes 3211, and the bolt head abuts against the surface of the corresponding first clamping plate 321 away from the anchor plate on the wind power generation foundation.
[0034] The above solution uses bolts and nuts to drive the two first clamping plates 321 to move towards each other, continuously reducing the distance between the two first clamping plates 321, thereby achieving the clamping function of the anchor plate on the wind power generation foundation. The structure is simple and easy to implement.
[0035] Reference Figures 1-3 In some other embodiments of this utility model, the fastener 32 includes a second clamping plate and a second fastener. There are two second clamping plates, and the two second clamping plates are spaced apart along the thickness direction of the handle 12. The second clamping plate located on the top of the anchor plate on the wind power generation foundation defines a space for accommodating the anchor plate on the wind power generation foundation. The second clamping plate is provided with a second fastening hole, which is a threaded hole. When the leveling scale 3 is fixed to the anchor plate on the wind power generation foundation, the second fastening hole is located opposite the anchor plate on the wind power generation foundation; the second fastener is inserted into the second fastening hole and the second fastener is threaded into the second fastening hole, and the second fastener is used to stop the anchor plate on the wind power generation foundation.
[0036] The above solution involves moving the second fastener toward the anchor plate on the wind power generation foundation, causing the distance between the second fastener and the second clamping plate located on top of the anchor plate on the wind power generation foundation to continuously decrease. The clamping function of the anchor plate on the wind power generation foundation is achieved by using the second fastener and the second clamping plate located on top of the anchor plate on the wind power generation foundation. The structure is simple and easy to implement.
[0037] Reference Figures 1-3 According to some optional embodiments of this utility model, the fixing member 32 is a magnet, which is used to adhere to the anchor plate on the wind power generation foundation to fix the scale plate 31 relative to the anchor plate on the wind power generation foundation. Since the wrench body 1, i.e., the pointer 2, does not drive the scale plate 31 to move during rotation, the magnetic attraction of the magnet can also ensure the use requirements. Moreover, this makes it easier to achieve the connection and fixation between the fixing member 32 and the anchor plate on the wind power generation foundation.
[0038] Reference Figures 1-3 According to some alternative embodiments of the present invention, the pointer 2 is detachably connected to the handle 12. Since the leveling wrench 100 is used in complex engineering environments, and the pointer 2 is relatively slender and easily damaged, the pointer 2 and handle 12 are made detachable. This allows only the pointer 2 to be replaced if it breaks, avoiding the need to replace the entire leveling wrench 100 and reducing maintenance costs. Furthermore, when the leveling wrench 100 is not in use, the pointer 2 can be removed from the handle 12, reducing the risk of damage to the pointer 2 and improving the applicability of the leveling wrench 100.
[0039] Reference Figures 1-3In some alternative embodiments of this utility model, one of the pointer 2 and the handle 12 has an upper limit groove, and the other has a limit post. The outer contour of the cross-section of the limit groove is non-circular, and the limit post passes through the limit groove. The outer contour of the cross-section of the limit post matches the outer contour of the cross-section of the limit groove. For example, the outer contour of the cross-section of the limit groove can be triangular, polygonal, or semi-circular. This allows for a detachable connection between the pointer 2 and the handle 12 via a plug-in method, facilitating the assembly and disassembly of the pointer 2 and the handle 12.
[0040] Reference Figures 1-3 In some alternative embodiments of this utility model, the handle 12 is provided with a third fastening hole, which is a threaded hole. The pointer 2 includes a mating post that passes through the third fastening hole and is threadedly engaged with it. This allows for a detachable connection between the pointer 2 and the handle 12 via a threaded connection, facilitating the assembly and disassembly of the pointer 2 and the handle 12. Furthermore, the connection between the pointer 2 and the handle 12 is reliable when they are assembled together.
