Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and more specifically, to a wind turbine foundation construction leveling mechanism. Background Technology

[0002] Wind power generation, as a clean and pollution-free renewable energy source, has been widely promoted and applied globally. In the wind turbine erection process, the construction quality of the turbine foundation directly determines the stability and safety of subsequent equipment operation; therefore, the accuracy of the construction surveying stage is crucial. The total station, as the core surveying equipment in this scenario, can provide high-precision data acquisition support for construction, but its normal operation depends on achieving horizontal calibration through a dedicated leveling device.

[0003] However, existing total station leveling devices generally suffer from insufficient structural stability, making it difficult for the total station to maintain a consistently stable state during surveying operations. Faced with this problem, operators often resort to a crude method of manual leveling, which is not only inefficient but also fails to meet the high-precision requirements of wind turbine foundation construction. This ultimately leads to significant errors in the collected data, potentially affecting the construction quality of the wind turbine foundation and posing a hidden danger to the safe operation of subsequent wind power equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a leveling mechanism for wind turbine foundation construction.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A leveling mechanism for wind turbine foundation construction includes a total station body and a bubble level, as well as a fixed base plate. A tilting and leveling component is symmetrically installed at the bottom of the fixed base plate; A lower support plate is fixedly installed on the base plate; The upper support mounting plate is installed on the lower support plate via the tilting and leveling component two; A bubble level is fixedly installed on the top surface of the upper support mounting plate, and clamping and fixing components are symmetrically installed on the upper support mounting plate; The total station body, which is detachably mounted on the upper support mounting plate, is fitted between two sets of clamping and fixing components.

[0006] Furthermore, the tilting and leveling assembly includes a mounting base. The mounting base has symmetrical mounting holes; The mounting base has an integrally formed inverted L-shaped support frame, and the inverted L-shaped support frame is threaded with a leveling thread post.

[0007] Furthermore, the top of the leveling threaded column is rotatably connected to the U-shaped support seat via a bearing. The U-shaped support seat has a T-shaped connecting block that is movably engaged inside, and the top surface of the connecting block is fixedly connected to the base plate. The connecting block moves through the U-shaped support seat via a rotating threaded shaft, and a limit nut is fitted on the thread of the rotating threaded shaft.

[0008] Furthermore, the tilting and leveling component two includes two semi-circular connecting side plates that are integrally formed with the lower support plate and symmetrically distributed; The upper support mounting plate has two symmetrically distributed semi-circular connecting side plates integrally formed at both ends; An arc-shaped guide groove is provided on one of the semi-circular connecting side plates; The semi-circular connecting side plate 2 is symmetrically provided with adjusting bolts that can move through the arc-shaped guide groove, and the end of the adjusting bolt that passes through the arc-shaped guide groove is threaded with a limiting thread sleeve.

[0009] Furthermore, the clamping and fixing assembly includes a support side plate fixed on the upper support mounting plate, a threaded abutment threaded post is threaded through the center of the support side plate, a bearing second is connected to one end of the abutment threaded post, and an abutment support plate is fixedly connected to the outer ring of the bearing second.

[0010] Furthermore, a rubber gasket is bonded to the side of the abutment support plate away from bearing two; Guide columns are symmetrically fixed on the contact support plate, which can move through the support side plate and slide with the support side plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

The symmetrically arranged clamping and fixing components in this application can firmly clamp and fix the total station body through the synergistic action of the contact threaded column, guide column and rubber gasket. This not only prevents the equipment from shifting and shaking during the measurement process, but also protects the surface of the equipment through the rubber gasket, which significantly improves the stability of the overall structure and ensures that the total station maintains a stable working state in complex construction environments. 4.

[0013] 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.

[0014] Please see Figure 1-4This utility model discloses a leveling mechanism for wind turbine foundation construction. Its core structure includes a fixed base plate 1, with tilting and leveling components 2 symmetrically mounted on its bottom and a lower support plate 3 fixedly installed on its top. The lower support plate 3 is movably connected to an upper support mounting plate 5 via tilting and leveling components 4. Through the synergistic action of tilting and leveling components 2 and 4, precise multi-directional tilt adjustment of the upper support mounting plate 5 can be achieved. A bubble level 6 (existing technology, no improvement is made) is fixedly embedded in the top surface of the upper support mounting plate 5. Simultaneously, two sets of clamping and fixing components 7 are symmetrically arranged on the top surface of the upper support mounting plate 5, with the two sets of clamping and fixing components 7 working together to clamp a total station body 8 detachably mounted on the upper support mounting plate 5. The bubble level 6 allows operators to intuitively and accurately determine whether the upper support mounting plate 5 and the total station body 8 are in a level working state, providing real-time reference for leveling operations.

[0015] For details on the implementation of this utility model, please refer to... Figure 2 The tilting and leveling assembly 2 consists of a mounting base 9, an inverted L-shaped support frame 10, a leveling threaded column 11, a bearing 12, a U-shaped support seat 13, a connecting block 14, a rotating threaded shaft 15, and a limiting nut 16. The mounting base 9 has symmetrically arranged fixing holes (not shown in the figure) for easy assembly of the overall structure. The inverted L-shaped support frame 10 is integrally formed with the mounting base 9, and the horizontal section of the inverted L-shaped support frame 10 is threaded through the leveling threaded column 11. The top of the leveling threaded column 11 is rotatably connected to the U-shaped support seat 13 via the bearing 12. The connecting block 14 is movably engaged inside the U-shaped support seat 13, and the top surface of the connecting block 14 is fixedly connected to the fixed base plate 1. The two sides of the connecting block 14 are movably connected through the U-shaped support seat 13 via the rotating threaded shaft 15, and the two ends of the rotating threaded shaft 15 are threadedly engaged with the limiting nut 16. During the leveling operation, the operator can first loosen the limit nut 16 based on the feedback from the bubble level 6, and then rotate the leveling threaded column 11. Under the action of the bearing 12, the fixed base plate 1 is driven to make a fine adjustment of the levelness. After the adjustment is in place, tighten the limit nut 16 to complete the positioning and ensure the stability after leveling.

[0016] For details on the implementation of this utility model, please refer to... Figure 3The tilting and leveling assembly 4 includes two semi-circular connecting side plates 17 integrally formed with the lower support plate 3 and symmetrically distributed, and two semi-circular connecting side plates 18 integrally formed with both ends of the upper support mounting plate 5 and symmetrically distributed. The semi-circular connecting side plates 17 have arc-shaped guide grooves 19, and the semi-circular connecting side plates 18 are symmetrically provided with adjusting bolts 20. These adjusting bolts 20 movably pass through the arc-shaped guide grooves 19, and a limiting threaded sleeve 21 is threaded onto the through end. During adjustment, loosen the limiting threaded sleeve 21, and adjust the angle of the upper support mounting plate 5 according to the tilt direction indicated by the bubble level 6 through the guiding action of the arc guide groove 19. After the angle is appropriate, tighten the limiting threaded sleeve 21 again to achieve precise leveling of the upper support mounting plate 5 in another dimension. Specifically, the tilt leveling component 1 2 mainly realizes the horizontal adjustment of the fixed base plate 1 in one direction, while the tilt leveling component 2 4 realizes the angle adjustment of the upper support mounting plate 5 in another direction perpendicular to it through the structure of the arc guide groove 19. The two work together to complete the all-round leveling of the upper support mounting plate 5, ensuring the horizontal accuracy of the total station body in the two-dimensional plane.

[0017] For details on the implementation of this utility model, please refer to... Figure 4 The clamping and fixing assembly 7 includes a support side plate 23 fixed to the upper support mounting plate 5. A threaded abutment threaded post 24 is threaded through the center of the support side plate 23. The inner end of the abutment threaded post 24 is rotatably connected to the abutment support plate 26 via a bearing 25. A rubber gasket 27 is bonded to the side of the abutment support plate 26 away from the bearing 25, and guide posts 22 are symmetrically fixed to both sides of the abutment support plate 26. The guide posts 22 movably pass through the support side plate 23 and slide in cooperation with it, while maintaining a perpendicular relationship with the abutment support plate 26. When the abutment threaded post 24 is rotated, with the rotational assistance of the bearing 25 and the precise guidance of the guide posts 22, the abutment support plate 26 can smoothly approach the total station body 8 and achieve abutment limit. The rubber gasket 27 enhances the clamping friction and prevents wear on the outer shell of the total station body 8, achieving a stable and gentle clamping and fixing effect.

[0018] In practical applications, this invention, through the coordinated operation of tilt leveling component 1 (2) and tilt leveling component 2 (4), enables multi-directional tilt adjustment of the upper support mounting plate 5, completely eliminating the traditional, crude leveling method of simple manual alignment and significantly improving leveling accuracy. Simultaneously, the overall structural design is simple and compact, and the clamping and fixing component 7 effectively prevents displacement and swaying of the total station body 8 during measurement, significantly enhancing the overall stability of the mechanism. The combination of precise leveling and reliable fixing performance effectively avoids measurement data errors caused by inaccurate leveling, providing stable and accurate equipment support for surveying operations in wind turbine foundation construction, and meeting the stringent requirements of wind power construction scenarios.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
