Description

Technical Field

[0001] The utility model relates to the technical field of wind power hoisting, in particular to a quick-adjusting and disassembly-free adjusting device for wind power. Background Art

[0002] During wind power construction and installation, specialized lifting tools must be used. Due to the particularity of wind power products, most products are eccentric, and it is often not easy to determine the center of gravity position, which undoubtedly increases the difficulty of hoisting. To ensure safe hoisting, when designing the lifting tool, generally, the method of increasing the counterweight is adopted to avoid the influence caused by eccentricity. Although this method is feasible, in the actual operation process, it is often necessary to continuously add counterweight blocks or remove counterweight blocks on the beam body and then conduct continuous trial hoisting until the beam body is balanced. The process of installing and fixing the counterweight blocks and removing the counterweight blocks undoubtedly requires a large amount of manpower and time, which obviously cannot meet the on-site installation requirements under the trend of rapid wind power installation.

[0016] The following is a further description with reference to the drawings to facilitate those skilled in the art to understand the technical solution of the present utility model. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present utility model.

[0017] In the following detailed description, for the purpose of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present utility model. However, it is obvious that one or more embodiments can be implemented without these specific details. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0018] Please refer to Figure 1, which is the overall structural schematic diagram of the quick-adjusting and non-detachable adjusting device for wind power of the utility model, includes a counterweight disk 1 with a bottom plate. A counterweight plate installation groove 11 is opened in the center of the counterweight disk 1. A clamping mechanism 2 is arranged in the counterweight plate installation groove 11. The clamping mechanism 2 is slidably connected with the sliding grooves 12 on both side panels of the counterweight disk 1. A driving motor 3 for driving the clamping mechanism 2 to clamp or loosen the counterweight plate 4 is assembled on the front side panel of the counterweight disk 1. A flange panel 13 for connecting with the beam body is arranged at the rear side of the counterweight disk 1.

[0019] Please continue to refer to Figures 1 - 3 , the clamping mechanism 2 includes a first counterweight stop bar 21, a second counterweight stop bar 22 and a transmission lead screw 23. The first counterweight stop bar 21 is arranged at one end of the counterweight plate installation groove 11 close to the driving motor 3. A first threaded connector 24 is fixedly arranged in the middle of it. First threaded holes are arranged at both ends of the first counterweight stop bar 21. The first threaded holes are fastened with the sliding grooves 12 on both side panels of the counterweight disk 1 through limit pins A25. The second counterweight stop bar 22 is arranged at one end of the counterweight plate installation groove 11 far from the driving motor 3. A limit card slot 26 with a buckle is arranged at one end of the middle part close to the first counterweight stop bar 21. A second threaded connector 27 is installed in the limit card slot 26. Second threaded holes are arranged at both ends of the second counterweight stop bar 22. The thread directions of the second threaded holes are the same as those of the first threaded holes. The second threaded holes are fastened with the sliding grooves 12 on both sides of the counterweight disk through limit pins B28. One end of the transmission lead screw 23 is connected with the driving motor 3 through a coupling, and the other end sequentially passes through the front side panel of the counterweight disk 1, the first threaded connector 24, the first counterweight stop bar 21, the second threaded connector 27, the second counterweight stop bar 22 and then is connected with a positioning threaded connector 29.

[0020] During specific implementation, first, butt the flange panel 13 of the counterweight disk with the flange surface of the beam body, and fasten them with bolts to make them an integral body.

[0021] The driving motor 3 is connected with the transmission lead screw 23 through a coupling. The transmission lead screw 23 penetrates into the counterweight disk. First, screw it into the first threaded connector 24 and the first counterweight stop bar 21. Limit pins A25 are respectively inserted into both sides of the first counterweight stop bar 21. The first counterweight stop bar 21 is allowed to move in the sliding groove of the counterweight disk 1. Then the transmission lead screw 23 is screwed into the second threaded connector 27, the second counterweight stop bar 22 and the positioning threaded connector 29. The second threaded connector 27 is arranged in the limit card slot 26. Limit pins B28 are respectively inserted into both sides of the second counterweight stop bar 22. The second counterweight stop bar 22 is allowed to move in the sliding groove of the counterweight disk 1. At this time, the quick-adjusting component is completed for assembly.

[0022] Lift the counterweight plates 4 one by one into the counterweight plate installation grooves 11 according to the usage requirements, position them using the first counterweight stop rod 21 and the second counterweight stop rod 22, and limit the counterweight plates 4 at any position in the counterweight plate installation grooves 11 through the limit pin A 25 and the limit pin B 28. During specific operation, start the drive motor 3 to drive the transmission lead screw 23 to rotate, thereby driving the relative movement between the first counterweight stop rod 21 and the transmission lead screw 23. When it is necessary to adjust the position of the counterweight plate 4, fasten the second threaded connector 27 in the limit card slot 26 through the buckle. Rotating the transmission lead screw 23 will inevitably drive the relative movement between the second counterweight stop rod 22 and the transmission lead screw 23 at the same time, realizing the synchronous movement of the position of the counterweight plate in the groove. When it is necessary to add or remove the counterweight plate 4, loosen the buckle, and the second threaded connector 27 is disengaged from the second counterweight stop rod 22. When rotating the transmission lead screw 23, only the first counterweight stop rod 21 moves relatively, which is convenient for adjusting the relative position between the second counterweight stop rod 22 and the first counterweight stop rod 21, ensuring more convenience when inserting or removing the counterweight plate 4.

[0023] In summary, the fast-adjusting and non-detachable adjusting device for wind power designed by the present utility model is directly connected to the beam body. By controlling the clamping and loosening of the clamping mechanism through the drive motor, it can quickly assemble and disassemble the counterweight plates, and can quickly clamp and fix the counterweight plates, meeting the on-site installation requirements under the trend of rapid installation of wind power.
