[0036] As introduced in the background technology, in the prior art, there is a problem that the wind turbine tower shakes greatly during the hoisting process. In order to solve the above technical problem, the utility model proposes a device for reducing the shaking of the tower and guiding quick hole alignment.

[0037] Embodiment 1

[0038] In a typical implementation of the present invention, reference is made to Figure 1As shown, a device for reducing tower shaking and guiding quick hole alignment includes a winch 2, which is fixed to a wind turbine foundation platform 1, and is located in the bottom section of the tower. A wire rope 4 is wound around the winch 2, and one end of the wire rope 4 can pass through a first opening at the top of a first section of the tower 3 and a second opening at the bottom of a second section of the tower 5 in sequence, and then be fixed by a first fastener. The other end of the wire rope 4 can pass through a third opening at the top of the second section of the tower 5 and a fourth opening at the bottom of the second section of the tower 5 in sequence, and then be fixed by a second fastener.

[0039] It needs to be explained that the first section of the tower 3 is located at the bottom of the second section of the tower 5, and the first section of the tower 3 and the second section of the tower 5 are arranged in sequence from bottom to top; it needs to be explained here that the first section of the tower 3 can be the bottom section of the tower, or it can be other non-top section of the tower, and the second section of the tower is above and adjacent to the first section of the tower. After the installation of a section of the tower above the bottom section of the tower is completed, the wire rope can be passed through the top opening of this section of the tower and the opening at the bottom of the upper tower layer and fixed, and then the upper tower layer can be installed, and the installation is completed until the installation of the top section of the tower is completed.

[0040] Among them, the first opening and the third opening are two of the multiple bolt holes on the flange of the first section of the tower, and the first opening and the third opening are located in the same plane; the second opening and the fourth opening are two of the multiple bolt holes on the flange 6 of the second section of the tower, and the second opening and the fourth opening are located in the same plane; the second opening and the first opening are the upper and lower bolt holes corresponding to each other after the tower is aligned, and the fourth opening and the third opening are the upper and lower bolt holes corresponding to each other after the upper and lower sections of the tower are aligned.

[0041] In this embodiment, reference Figure 2 As shown, the two ends of the steel wire rope 4 are connected as a whole through one or more first fasteners or second fasteners after passing through the second opening and the fourth opening of the lower flange 6 of the second section tower 5 respectively;

[0042] The first fastener or the second fastener is detachably connected to the two ends of the wire rope. The first fastener or the second fastener is specifically a wire rope buckle. The two ends of the wire rope are respectively passed through the wire rope buckle and locked by the bolts and nuts corresponding to the wire rope buckle. After the bolts are installed at the bolt holes 7 at the non-wire rope positions at the flanges of the two sections of the tower, the wire rope buckle and the wire rope are removed, and the bolts at the first opening and the second opening are installed.

[0043] In addition, the winch 2 can be detachably installed on the wind turbine foundation platform 1. Specifically, the bottom of the winch 2 is installed on the wind turbine foundation platform 1 by a plurality of bolts. After the tower is installed, the staff can enter the tower to dismantle the winch.

[0044] In order to facilitate the removal of the winch from the tower after dismantling, the winch 2 is provided with at least two hooks, and multiple hooks are arranged around the winch 2. With the assistance of the staff, the crane is connected to the winch through the hooks, and the crane can lift the winch out of the tower.

[0045] In this embodiment, the winch 2 is connected to the controller, which is a PLC controller or other types of controllers; the controller has a control button, and the controller is located on the outside of the bottom section of the tower, and the bottom section of the tower is provided with an opening, and the winch wire passes through the opening and is connected to the controller, and the controller may not be fixed to the bottom end of the tower, so that the staff can control the winch on the outside of the tower;

[0046] Alternatively, the controller is connected to the remote control through existing radio signals. The controller is located at the winch housing. The staff controls the movement of the winch through the remote control at the top of the second tower section 5 according to the connection status of the two adjacent tower sections.

[0047] The hole-aligning device provided in this embodiment has a steel wire rope 4 wound around the winch 2. Both ends of the steel wire rope pass through corresponding bolt holes at flanges of upper and lower adjacent tower sections and are connected as a whole through a first fastener or a second fastener, which greatly facilitates the stability of the second tower section during the hoisting process. The crane hoists the second tower section, and controls the winch 2 to rotate and recycle the steel wire rope 4 through a controller. The steel wire rope 4 connects the upper and lower adjacent tower sections, effectively guiding the second tower section, reducing the shaking of the second tower section 5 in the air, and at the same time aligning the corresponding bolt holes of the upper and lower tower sections, thereby improving the installation efficiency of the tower.

[0048] Embodiment 2

[0049] The difference between this embodiment and the first embodiment is that the first fastener and the second fastener respectively fix the two ends of the steel wire rope 4. It is easy to understand that the structures of the first fastener and the second fastener are the same or different. The first fastener and the second fastener are detachably fixed to the ends of the steel wire rope 4. In this way, after the second section of the tower 5 is hoisted into place, bolts at other positions are installed first, and then the first fastener and the second fastener are removed, and the steel wire rope is released from the corresponding opening, which facilitates the bolts to pass through the corresponding bolt holes to achieve a stable connection between the two adjacent sections of the tower.

[0050] Specifically, the first fastener and the second fastener are respectively a wire rope buckle, and the wire rope buckle is specifically an existing wire rope buckle, and the wire rope buckle can pass through the wire rope end after being looped, and is locked by the bolt and nut of the wire rope buckle, and after the second section of the tower is hoisted in place, the nut can be loosened relative to the bolt, so that the first fastener and the second fastener are loosened;

[0051] There are multiple first fasteners and second fasteners respectively, the spacing between two adjacent first fasteners at one end of the wire rope 4 is set, and the spacing between two adjacent second fasteners at the other end of the wire rope 4 is set. The setting of multiple first fasteners and second fasteners ensures that the end of the wire rope is stably fixed.

[0052] Thus, the two ends of the wire rope 4 are folded in half and passed through the wire rope buckle. The outer diameter of the wire rope buckle is larger than the inner diameter of the first opening, the second opening, the third opening or the fourth opening, so as to prevent the first fastener or the second fastener from coming out of the corresponding bolt hole.

[0053] In addition, a hook is provided on the inner wall of the second tower section 5, and the folded end of the wire rope can be hung on the hook, which can further ensure that the end of the wire rope is stably fixed, which is conducive to the rapid and accurate lifting of the upper tower section.

[0054] It should be noted that the hook can be detachably installed in the second section tower 5. Specifically, a threaded hole is arranged in the second section tower 5 near the bottom of the first section tower 3. The detachable hook is installed in the second section tower 5 through a threaded structure. In this way, after the second section tower 5 and the first section tower 3 are installed, the hook can be removed by rotation. The hook part of the hook is arranged upward, that is, the short side of the hook part is arranged above the hook body, which is conducive to the stable fixation of the end of the wire rope.

[0055] In the hole alignment device provided in this embodiment, the wire rope 4 is wound around the hoist 2, and the two ends of the wire rope 4 pass through the upper and lower adjacent tower sections and are fixed by the first fastener or the second fastener. The crane hoists the upper tower section, and the hoist 2 is controlled by the controller to rotate and recycle the wire rope 4. At the beginning, the recovery speed of the wire rope 4 should be controlled to avoid excessive force. When the second tower section 5 is hoisted to the set height and its position is basically aligned with the position of the first tower section 3, the hoist 2 is controlled to increase the traction force on the wire rope 4, so that the lower flange of the second tower section 5 is aligned with the upper flange 6 of the first tower section 3, and then the bolts (a plurality of bolt holes are arranged in one circle) at the other bolt holes 7 (the bolt holes in the upper flange of the first tower section excluding the first opening and the third opening) at the flanges of the two tower sections are installed. After the bolts at the other bolt holes 7 are installed, the first fastener and the second fastener are removed, and the bolts at the corresponding positions are installed, and the installation work of the upper tower section above the second tower section is continued according to the above steps.

[0056] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
