Description

Technical Field

[0001] This utility model relates to the technical field of flange assembly devices, specifically a wind turbine tower flange assembly device. Background Technology

[0002] When installing a wind turbine tower, the bottom support tower, fixed to the ground, needs to be connected to the upper tower connecting the generator casing via flanges. The upper and lower flanges must be aligned during connection. A search reveals that utility model patent CN209483538U discloses a limiting device for flange connections in wind turbine towers. This device comprises a limiting device, a bottom support tower, and a top tower. A flange is welded to the top of the bottom support tower and to the bottom of the top tower. Both the flange and the top tower have a set of annular insertion holes on their flange surfaces. A limiting device, in a T-shape, is inserted into one of these holes.

[0003] The existing wind turbine tower flange assembly system uses only one flange hole for positioning, which is not accurate enough and requires multiple positioning operations, resulting in low efficiency. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a wind turbine tower flange assembly device, which solves the problem that the existing wind turbine tower flange assembly devices only use one flange hole for positioning, which is not accurate enough, requires multiple positioning, and has low efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower flange assembly device, comprising an adjusting sleeve, wherein two threaded bends are connected internally by threads, each threaded bend is fixedly connected to a sleeve at its end, a connecting frame is fixedly connected to the bottom of the sleeve, an assembly sleeve is fixedly connected to the bottom of the connecting frame, and a lubrication mechanism is provided inside the adjusting sleeve.

[0006] Preferably, a rubber pad is fixedly connected to the inner side of the jacket. The rubber pad is made of rubber. The rubber pad increases the friction between the jacket and the tower body.

[0007] Preferably, a non-standard nut is fixedly connected to the middle of the outer side of the adjusting sleeve, and the non-standard nut and the adjusting sleeve are an integral structure. The non-standard nut makes it easier for workers to rotate the adjusting sleeve with tools.

[0008] Preferably, the lubrication mechanism includes a hollow shell slidably connected inside the adjusting sleeve. A pressure block and a sponge block are slidably connected to the inner side of the hollow shell, and the pressure block and sponge block are in contact with each other. A fixing post is fixedly connected to the sponge block, penetrating the hollow shell and slidably connected to it. The end of the fixing post is fixedly connected to the inner wall of the adjusting sleeve, and a spring is sleeved on the outer side of the fixing post. This lubrication mechanism provides lubrication for the threaded connection between the threaded bend and the adjusting sleeve, allowing the device to be used for extended periods without easily becoming clogged due to rust.

[0009] Preferably, one end of the spring is fixedly connected to the pressure block, and the other end of the spring is fixedly connected to the inner surface of the hollow shell. By using the spring, the elastic force can be applied to the hollow shell.

[0010] Preferably, the hollow shell has an oil outlet hole on its side wall, and the position of the oil outlet hole corresponds to that of the sponge block. The oil outlet hole facilitates the discharge of lubricating oil from the sponge block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model sets up an adjusting sleeve, with threaded bends at both ends of the adjusting sleeve that are threadedly connected to it. Then, at the end of the threaded bends, components such as a jacket, a connecting frame, and an assembly sleeve are set up. The jacket fits against the tower body, while the assembly sleeve fits against the flange. In this way, when the two towers are assembled through their respective flanges, they can be aligned, which facilitates quick connection between the flanges.

[0013] 2. This utility model provides a lubrication mechanism inside the adjusting sleeve. When the threaded bend enters the adjusting sleeve in the reverse direction, the threaded bend can push the hollow shell, causing the sponge block inside the hollow shell to be subjected to the reaction force from the pressure block, thereby squeezing and releasing the lubricating oil. The lubricating oil then lubricates the threaded connection between the threaded bend and the adjusting sleeve, allowing the device to be used for a long time without being easily blocked by rust.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 A wind turbine tower flange assembly device includes an adjusting sleeve 1. Inside the adjusting sleeve 1 are two threaded elbows 2 connected by threads. Each threaded elbow 2 has a clamp 3 fixedly connected to its end. A rubber pad 4 is fixedly connected to the inner side of the clamp 3. The rubber pad 4 increases the friction between the entire assembly and the tower body. A connecting frame 5 is fixedly connected to the bottom of the clamp 3, and an assembly sleeve 6 is fixedly connected to the bottom of the connecting frame 5. A non-standard nut 7 is fixedly connected to the middle of the outer side of the adjusting sleeve 1, and the non-standard nut 7 is an integral part of the adjusting sleeve 1. The non-standard nut 7 facilitates the rotation of the adjusting sleeve 1 by workers using tools.

[0021] Please see Figure 3-4 The adjusting sleeve 1 is equipped with a lubrication mechanism 8. This mechanism lubricates the threaded connection between the threaded bend 2 and the adjusting sleeve 1, allowing the device to be used for extended periods without rusting or clogging. The lubrication mechanism 8 includes a hollow shell 81 slidably connected inside the adjusting sleeve 1. A pressure block 82 and a sponge block 83 are slidably connected to the inner side of the hollow shell 81, and the pressure block 82 and sponge block 83 are in contact with each other. A fixing post 84 is fixedly connected to the sponge block 83, penetrating the hollow shell 81 and slidably connected to it. The end of the fixing post 84 is fixedly connected to the inner wall of the adjusting sleeve 1. A spring 85 is fitted on the outer side of the fixing post 84. One end of the spring 85 is fixedly connected to the pressure block 82, and the other end is fixedly connected to the inner surface of the hollow shell 81. The spring 85 allows elastic force to be applied to the hollow shell 81. An oil outlet hole 86 is provided on the side wall of the hollow shell 81, and the position of the oil outlet hole 86 corresponds to that of the sponge block 83. The oil outlet 86 facilitates the discharge of lubricating oil from the sponge block 83.

[0022] The specific implementation process of this utility model is as follows: In use, the two tower cylinders are first brought into contact through their respective flanges. Then, the two jackets 3 are placed on the outside of the upper tower cylinder body. Then, the toolman uses a tool to rotate the non-standard nut 7, which in turn rotates the adjusting sleeve 1, so that the two threaded bends 2 move towards each other until the rubber pad 4 on the jacket 3 contacts the tower body. The assembly sleeve 6 below the jacket 3 aligns the flanges of the tower cylinders, which facilitates quick connection between the flanges. Moreover, when the threaded bend 2 enters the adjusting sleeve 1 in the reverse direction, the threaded bend 2 can push the hollow shell 81, so that the sponge block 83 inside the hollow shell 81 is subjected to the reaction force from the pressure block 82, thereby squeezing and releasing the lubricating oil. The lubricating oil lubricates the threaded connection between the threaded bend 2 and the adjusting sleeve 1, so that the device can be used for a long time and is not easy to be blocked by rust.
