The overall structure is light and compact, which can greatly reduce the construction time, is highly efficient and easy to carry.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A portable universal pre-tightening tool for wind power anchor nuts comprises a connecting plate, a connecting component is provided at the center position of one side of the connecting plate, fixing parts are symmetrically provided on the side of the connecting plate away from the connecting component, and clamping plates are respectively provided on the sides where the two fixing parts are close to each other, and the clamping plates are located at the end of the fixing part away from the connecting plate, and each of the clamping plates itself is arranged at an angle.

[0006] Furthermore, the fixing member includes two fixing plug plates plugged into the connecting plate, and the two fixing plug plates are arranged at an angle.

[0007] Furthermore, the clamping plate and the fixing member are detachably connected via a connecting block.

[0008] Furthermore, a first hook is provided on one side of the connecting block, a first hanging ring is provided on the side of the connecting block away from the first hook, a second hanging ring connected to the first hook is provided on the fixing member, and a second hook connected to the first hanging ring is provided on the back side of the splint.

[0009] Furthermore, a plurality of the second hanging rings are provided on the fixing member.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] During the pre-tightening construction of the anchor nuts of the wind power foundation, this patent is installed and tightened through the connecting parts and the electric wrench, the anchor nuts are clamped and fixed by two clamping plates, the electric wrench is started, the connecting plate is rotated, and the two clamping plates are driven to rotate to complete the pre-tightening of the anchor nuts. The overall structure of this patent is light and compact, easy to carry, and can greatly shorten the construction time and improve construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0019] Embodiment: A portable universal pre-tightening tool for wind power anchor nuts, the main structure of which includes a circular connecting plate 1, a connecting component 2 is provided at the center position of one side of the connecting plate 1 to ensure that the fixing member 3 and the clamping plate 4 rotate around the central axis of the connecting plate 1 to prevent eccentric rotation, a fixing member 3 is symmetrically provided on the side of the connecting plate 1 away from the connecting component 2, the fixing member 3 includes two fixing plug-ins 5 that are plugged into the connecting plate 1 with interference fit, the two fixing plug-ins 5 are arranged at an angle, and a clamping plate 4 is provided on the side close to the two fixing members 3, respectively, the clamping plate 4 is located at the end of the fixing member 3 away from the connecting plate 1, each of the clamping plates 4 itself is bent at an angle of 120°, and the angle of the two fixing plug-ins 5 can be The two clamps 4 are used to clamp and fix the anchor nuts. The clamps 4 and the fixed plug plates 5 are detachably connected through the connecting blocks 6. A first hook 7 is provided on one side of the connecting block 6. A first hanging ring 8 is provided on the side of the connecting block 6 away from the first hook 7. Each of the fixed plug plates 5 is provided with a second hanging ring 9 hung with the first hook 7. A second hook 10 hung with the first hanging ring 8 is provided on the back side of the clamp 4 to realize the detachability of the clamp 4 and the fixed plug plate 5. A plurality of the second hanging rings 9 are provided on the fixed plug plate 5. For nuts of different models and specifications, clamps 4 of different specifications can be replaced by replacing or adding or reducing the connecting blocks 6, so as to clamp nuts of different models.
