Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower construction technology, and in particular to a leveling device for an integral pre-embedded component of a wind turbine foundation. Background Technology

[0002] A wind turbine tower is the support structure of a wind turbine generator. It primarily supports the turbine and absorbs vibrations. The foundation ring beneath the tower bears immense vertical pressure and lateral bending moments. Existing foundation rings are generally buried... It is set in the corresponding concrete foundation, and the upper end of the tower foundation ring is connected to the bottom of the generator tower through a locking flange.

[0003] A search revealed, for example, a wind turbine tower foundation ring reinforcement node structure disclosed in patent publication number CN220285909U, comprising a fixed ring, an internal connecting ring, and four connecting plates fixedly connected to the outer surface of the connecting ring. The end of each connecting plate furthest from the connecting ring is fixedly connected to the inner wall of the fixed ring. A fixed cylinder is fixedly connected to the upper surface of the connecting ring, and a mounting flange is fixedly connected to the top of the fixed cylinder. The fixed ring and the foundation are cast together using fixing lugs on the fixed ring in conjunction with embedded parts.

[0004] Based on the above search and combined with existing technology, it was found that existing pre-embedded structures similar to those disclosed above include hundreds of embedded parts (anchor rods), with the entire embedded part weighing several tons. Inaccurate verticality control leads to difficulties in connecting the top anchor plate, and the levelness after connection is difficult to guarantee. Therefore, a leveling device for the overall pre-embedded parts of wind power foundations is proposed to improve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a leveling device for integral embedded parts of wind power foundations to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a leveling device for an integral pre-embedded component of a wind power foundation, comprising an auxiliary leveling assembly disposed between a lower anchor plate, an upper anchor plate, and multiple anchor rods; The lower anchor plate and the upper anchor plate are respectively provided with multiple first mounting holes and second mounting holes at equal intervals along their own circumference, and the multiple first mounting holes on the lower anchor plate are provided in a one-to-one correspondence with the second mounting holes on the upper anchor plate. The first mounting holes and the second mounting holes are respectively inserted and matched with multiple anchor rods. After the upper anchor plate is placed on the upper side of the lower anchor plate and the auxiliary leveling component is fixed to the upper end of the lower anchor plate, the auxiliary leveling component drives the upper anchor plate to move vertically upward.

[0007] As a further supplement to this solution, the auxiliary leveling components include a positioning rod, a support frame, a threaded rod, and a drive motor; Multiple positioning rods are provided, and the multiple positioning rods are fixed at equal intervals to the side end of the support frame. The first mounting hole and the second mounting hole are respectively inserted and engaged with the multiple positioning rods. The threaded rod is rotatably installed in the middle of the bottom end of the support frame. The drive motor is detachably installed in the top end of the support frame, and the output end of the drive motor is coaxially connected with the threaded rod. The inner side of the lower anchor plate is fixed with a first mounting bracket for the threaded rod to rotate and connect, and the inner side of the upper anchor plate is fixed with a second mounting bracket for the threaded rod to pass through.

[0008] As a further supplement to this solution, a positioning structure is provided between the lower anchor plate and the upper anchor plate.

[0009] As a further supplement to this solution, the positioning structure includes multiple positioning posts that are circumferentially fixed at the lower end of the upper anchor plate, and multiple positioning holes that are circumferentially fixed at the lower anchor plate, with the multiple positioning posts and multiple positioning holes corresponding and matching one-to-one.

[0010] As a further supplement to this solution, multiple positioning sleeves are fixed at equal intervals around the upper circumference of the lower anchor plate. The multiple positioning sleeves are located at multiple positioning holes, and the positioning sleeves are inserted into the positioning posts.

[0011] As a further supplement to this solution, a protective cover is movably inserted into the upper end of the positioning sleeve.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, by setting up an auxiliary leveling component, during construction, the lower anchor plate is first fixed in a predetermined position and leveled. Then, the upper anchor plate is placed on the upper side of the lower anchor plate. Subsequently, multiple positioning rods are inserted into the second mounting holes on the upper anchor plate and the first mounting holes on the lower anchor plate, fixing the positioning rods to the lower anchor plate. At the same time, the threaded rod is threaded through the second mounting bracket and inserted into the first mounting bracket. Then, multiple anchor rods are inserted into the second mounting holes on the upper anchor plate and the first mounting holes on the lower anchor plate, fixing the anchor rods to the lower anchor plate. Subsequently, the threaded rods are driven to rotate by a drive motor, and the rotating threaded rods drive the upper anchor plate to move vertically upward, realizing the synchronous adjustment of the verticality of multiple anchor rods while ensuring the horizontality of the upper anchor plate after adjustment.

[0013] 2. In this utility model, by using the insertion and connection between the positioning sleeve and the positioning column, mud is less likely to splash into the positioning sleeve during the process of fixing the lower anchor plate. Thus, the insertion and connection between the positioning sleeve and the positioning column can improve the initial levelness of the upper anchor plate. Attached Figure Description

[0017] 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.

[0018] Example 1: Reference Figures 1-5 The wind power foundation integral embedded part leveling device shown includes an auxiliary leveling component set between the lower anchor plate 1, the upper anchor plate 2 and multiple anchor rods 3. It should be noted that the actual number of anchor rods 3 during construction is much greater than the number of anchor rods 3 shown in the figure.

[0019] The lower anchor plate 1 and the upper anchor plate 2 are respectively provided with a plurality of first mounting holes 101 and second mounting holes 201 at equal intervals along their own circumference. The plurality of first mounting holes 101 on the lower anchor plate 1 are provided in a one-to-one correspondence with the second mounting holes 201 on the upper anchor plate 2. The first mounting holes 101 and the second mounting holes 201 are all inserted into and engaged with a plurality of anchor rods 3.

[0020] Regarding the auxiliary leveling components, specifically, such as Figure 3 As shown, the auxiliary leveling assembly includes positioning rods 4, support frame 5, threaded rods 6, and drive motor 7. A conventional electric motor, such as a TZ155X020 model, can be used. Multiple positioning rods 4 are provided, equidistantly fixed to the side ends of the support frame 5. The first mounting hole 101 and the second mounting hole 201 are correspondingly inserted into the multiple positioning rods 4. The threaded rod 6 is rotatably mounted at the bottom center of the support frame 5. The drive motor 7 is detachably mounted at the top of the support frame 5, for example, by bolt connection (not shown in the figure). The output end of the drive motor 7 is coaxially connected to the threaded rod 6, for example, by a locking block and a locking slot (not shown in the figure). A first mounting bracket 11 for rotatably connecting the threaded rod 6 is fixed to the inner side of the lower anchor plate 1. Of course, a bearing adapted to the end of the threaded rod 6 can be provided on the first mounting bracket 11. A second mounting bracket 21 for the threaded rod 6 to thread through is fixed to the inner side of the upper anchor plate 2.

[0021] Based on the above structural arrangement, during construction, the lower anchor plate 1 is first fixed in the predetermined position, and leveled using conventional techniques, such as using a level. Then, the upper anchor plate 2 is placed on the upper side of the lower anchor plate 1. Subsequently, multiple positioning rods 4 are inserted into the second mounting holes 201 on the upper anchor plate 2 and the first mounting holes 101 on the lower anchor plate 1, fixing the positioning rods 4 to the lower anchor plate 1. At the same time, the threaded rod 6 is threaded through the second mounting bracket 21 and inserted into the first mounting bracket 11. Then, multiple anchor rods 3 are inserted into the second mounting holes 201 on the upper anchor plate 2 and the first mounting holes 101 on the lower anchor plate 1, fixing the anchor rods 3 to the lower anchor plate 1. Subsequently, the drive motor 7 drives the threaded rod 6 to rotate, and the rotating threaded rod 6 drives the upper anchor plate 2 to move vertically upward, achieving synchronous adjustment of the verticality of multiple anchor rods 3 while ensuring the levelness of the upper anchor plate 2 after adjustment.

[0022] A positioning structure is provided between the lower anchor plate 1 and the upper anchor plate 2 to ensure that the multiple second mounting holes 201 on the upper anchor plate 2 correspond accurately to the multiple first mounting holes 101 on the lower anchor plate 1.

[0023] Specifically, the positioning structure includes multiple positioning posts 22 that are circumferentially fixed at the lower end of the upper anchor plate 2, and multiple positioning holes that are circumferentially fixed at the lower anchor plate 1. The multiple positioning posts 22 and the multiple positioning holes are matched one-to-one.

[0024] Example 2: In order to prevent mud from splashing onto the upper surface of the lower anchor plate 1 during the fixing process, which would prevent the upper anchor plate 2 from being placed flat, multiple positioning sleeves 12 are fixed at equal intervals around the upper circumference of the lower anchor plate 1. The multiple positioning sleeves 12 are located at multiple positioning holes. The positioning sleeves 12 are inserted into the positioning posts 22. During the fixing of the lower anchor plate 1, mud is less likely to splash into the positioning sleeves 12. In this way, the insertion and cooperation between the positioning sleeves 12 and the positioning posts 22 can improve the initial levelness of the upper anchor plate 2.

[0025] To further prevent mud from splashing into the positioning sleeve 12, a protective cover 13 is movably inserted into the upper end of the positioning sleeve 12. During the process of fixing the lower anchor plate 1, the protective cover 13 can be used to cover the top of the positioning sleeve 12. After the lower anchor plate 1 is fixed, the protective cover 13 can be removed, and the positioning sleeve 12 can be inserted and matched with the positioning column 22.

[0026] It should be noted that the specific models and specifications of the electrical equipment involved in this solution need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be described in detail here. The power supply and principles of the electrical equipment involved are clear to those skilled in the art, and will not be described in detail here.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
