[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1 —4. Detailed description of specific embodiments of this utility model.

[0028] In this utility model, the terms "connection" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure.

[0029] In this utility model, the terms "inner", "outer", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not 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.

[0030] This utility model embodiment provides a tool for disassembling and assembling anchor bolt nuts for wind turbine foundations, see attached document. Figure 1 and Figure 2, the disassembling and assembling tool for the anchor bolt nut of the fan foundation includes a sleeve 10 and a rocker 20. The sleeve 10 has a through hole 110 along the axial direction, and the through hole 110 is used to cooperate with the anchor bolt nut to be disassembled and assembled; the rocker 20 is in a "ji" - shaped structure, including a connecting section 210, a first handheld section 220 and a second handheld section 230 connected in sequence. The end of the connecting section 210 is fixedly arranged at the edge position of the sleeve 10. There is a first distance L1 between the first handheld section 220 and the central axis of the sleeve 10, a second distance L2 between the second handheld section 230 and the central axis of the sleeve 10, and a third distance L3 between the connecting section 210 and the central axis of the sleeve 10. Among them, the first distance L1, the second distance L2 and the third distance L3 satisfy: the first distance L1 is greater than the second distance L2, and the first distance L1 is greater than the third distance L3.

[0031] It should be noted that the through hole 110 is also used to pass through the anchor bolt. The connecting section 210 is connected to the edge position of the sleeve 10, rather than the central position of the sleeve 10.

[0032] The working principle of a disassembling and assembling tool for the anchor bolt nut of the fan foundation provided by an embodiment of the present utility model is as follows: When it is necessary to install or disassemble the anchor bolt nut, first, the anchor bolt nut is sleeved on the anchor bolt, and then the sleeve 10 is sleeved on the anchor bolt nut. A worker can hold the second handheld section 230 with one hand to stabilize the rocker 20; hold the first handheld section 220 with the other hand and rotate the rocker 20 to rotate and install the anchor bolt nut at a certain position on the anchor bolt, or screw out the anchor bolt nut from the anchor bolt.

[0033] For a disassembling and assembling tool for the anchor bolt nut of the fan foundation provided by an embodiment of the present utility model, on the one hand, compared with the rocker 20 being connected to the central position of the sleeve 10, in this application, by setting the rocker 20 as a "ji" - shaped structure and connecting the end of the connecting section 210 of the rocker 20 to the edge position of the sleeve 10, the length of the force arm is increased, thereby increasing the torque, making it labor - saving to disassemble and assemble the anchor bolt nut and reducing the labor intensity of workers; on the other hand, by setting two handheld sections, it is possible to quickly disassemble and assemble the anchor bolt nut and improve the disassembling and assembling efficiency.

[0034] In an embodiment of the present utility model, in one implementation manner, the rocker 20 can be an integral structure or a split structure. For example, the rocker 20 is an integral structure and is formed into a "ji" - shaped structure by bending, and among them, the axes of the connecting section 210 and the second handheld section 230 are collinear.

[0035] In an embodiment of the present utility model, a rotating sleeve (not shown in the figure) is pivotally connected to the second handheld section 230. With this setting, when holding the rotating sleeve with one hand, the rocker 20 can rotate relative to the rotating sleeve.

[0036] In this embodiment of the invention, a second flexible sleeve is provided on the outer side of the rotating sleeve. It should be noted that the second flexible sleeve can be a rubber sleeve or a silicone sleeve. This design improves operational comfort.

[0037] In this embodiment of the invention, a bearing (not shown in the figure) is provided between the rotating sleeve and the second hand-held section 230. This arrangement reduces the friction between the rotating sleeve and the second hand-held section 230, making the rocker arm 20 rotate more smoothly.

[0038] In this embodiment of the invention, a first flexible sleeve (not shown in the figure) is fitted over the outer side of the first hand-held segment 220. It should be noted that the first flexible sleeve can be a rubber sleeve or a silicone sleeve. This design improves operational comfort.

[0039] In this embodiment of the invention, the second handpiece 230 is fitted with a second flexible sleeve (not shown in the figure). It should be noted that the second flexible sleeve can be a rubber sleeve or a silicone sleeve. This design improves operational comfort.

[0040] In this embodiment of the invention, the sleeve 10 can be an integral, non-adjustable structure or an adjustable structure. Details are as follows:

[0041] See appendix Figure 1 and Figure 4 In the first embodiment, the anchor nut is a hexagonal nut, and the through hole 110 is a regular hexagonal hole, the inner wall of which can fit the hexagonal nut; the end of the connecting section 210 is fixed to the outer wall of the sleeve 10. It should be noted that the cross-sectional shape of the outer contour of the sleeve 10 can be circular or polygonal; specifically, the cross-sectional shape of the outer contour of the sleeve 10 is a regular hexagon. This design is simple in structure and convenient to use.

[0042] See appendix Figure 2 and Figure 3 In the second embodiment, the anchor nut is a hexagonal nut; the sleeve 10 may include clamping arms 130 and adjusting rods 140. There are two clamping arms 130 arranged opposite each other. The adjusting rod 140 passes through the ends of the two clamping arms 130 sequentially. The first end of the adjusting rod 140 abuts against the outer wall of one of the clamping arms 130, and the second end of the adjusting rod 140 is threadedly connected to an adjusting nut 150, which is used to adjust the distance between the two clamping arms 130. Both clamping arms 130 have V-grooves 131, which are arranged opposite each other and can respectively engage with the corners of the hexagonal nut. The end of the connecting section 210 is fixed to one of the clamping arms 130. This configuration can accommodate anchor nuts of different sizes, improving the practicality of the disassembly and assembly tools.

[0043] In the second embodiment described above, there are at least two adjusting rods 140, which are spaced apart along the length of the clamping arm 130 and located on both sides of the V-groove 131.

[0044] See appendix Figure 1 and Figure 4 In the first embodiment described above, the sleeve 10 has a first limiting structure that extends radially inward along the through hole 110 and protrudes from the inner wall surface of the through hole 110. If a hexagonal nut is fitted into the through hole 110, the end face of the hexagonal nut can abut against the lower end face of the first limiting structure. With this configuration, if the anchor nut is not in contact with the fastening surface and is in a suspended state, the sleeve 10 is fitted onto the anchor nut, and the lower end face of the first limiting structure abuts against the upper end face of the anchor nut, thereby preventing the sleeve 10 from slipping off the anchor nut.

[0045] For the first embodiment described above, the type of the first limiting structure is not limited, as follows:

[0046] For example, see Appendix Figure 4 The first limiting structure includes a first limiting block 121, which has at least two blocks spaced apart in the circumferential direction on the inner wall surface of the through hole 110 or the upper end surface of the sleeve 10. This arrangement allows the lower surface of the first limiting block 121 to abut against the upper end surface of the anchor nut, preventing the sleeve 10 from slipping off the anchor nut.

[0047] For example, see Appendix Figure 1 The first limiting structure is a limiting ring 122, which protrudes from the inner wall of the through hole 110 or the upper end face of the sleeve 10. With this configuration, the lower surface of the limiting ring 122 can abut against the upper end face of the anchor nut, preventing the sleeve 10 from slipping off the anchor nut.

[0048] In the second embodiment described above, the clamping arm 130 has a second limiting structure, which is fixed to the upper end face of the clamping arm 130 and located above the V-groove 131; or, the second limiting structure is fixed to the inner wall surface of the V-groove 131; if the corner of the hexagonal nut fits into the V-groove 131, the end face of the hexagonal nut can abut against the lower end face of the second limiting structure. With this configuration, the lower surface of the second limiting structure can abut against the upper end face of the anchor nut, preventing the sleeve 10 from slipping off the anchor nut.

[0049] For the first embodiment described above, the type of the second limiting structure is not limited, as follows:

[0050] For example, see Appendix Figure 3The second limiting structure is a limiting plate 161, which is located on the upper end face of the clamping arm 130 and above the V-groove 131; or, the limiting plate 161 is fixed to the inner wall of the V-groove 131. With this configuration, the lower surface of the limiting plate 161 can abut against the upper end face of the anchor bolt nut, preventing the sleeve 10 from slipping off the anchor bolt nut.

[0051] For example, the second limiting structure is a second limiting block, which has at least two blocks that are spaced apart and protrude from the V-groove 131. With this configuration, the lower surface of the second limiting block can abut against the upper end face of the anchor bolt nut, preventing the sleeve 10 from slipping off the anchor bolt nut.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
