Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to a device for leveling the side of a longitudinal flange of a wind tower. Background Technology

[0002] During the manufacturing and installation of wind turbine towers, the longitudinal flange, as a key connecting component, directly affects the stability and assembly accuracy of the overall structure of the wind turbine tower due to the horizontality of its side.

[0003] In existing technologies, the lack of specialized testing and leveling devices often leads to reliance on manual visual inspection or simple tools for flange side leveling inspection. This results in problems such as unintuitive testing and low accuracy. Furthermore, leveling often involves manual tapping or simple mechanical pressure, which has drawbacks such as uncontrollable force, low leveling efficiency, and easy excessive deformation of the flange. In severe cases, this can lead to uneven connection gaps and unbalanced bolt forces during wind tower assembly, creating potential structural safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the reliance on manual visual inspection or simple tools for flange side levelness detection, which results in unintuitive inspection and low accuracy. Furthermore, the use of manual tapping or simple mechanical pressure during leveling leads to uncontrollable force, low leveling efficiency, and excessive flange deformation, which can cause uneven joint gaps and bolt stress imbalance during wind tower assembly, posing a potential structural safety hazard. Therefore, this invention proposes a longitudinal flange side leveling device for wind towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A longitudinal flange side leveling device for wind towers includes: a processing table, on which a guide for guiding and supporting the flange is provided, and a leveling component for leveling the flange is also provided on the processing table.

[0006] As a preferred embodiment of the wind tower longitudinal flange side leveling device of this utility model, the leveling component includes a mounting frame fixedly mounted on the processing table and a roller for sliding the flange to the next process. A cylinder is fixedly mounted on the mounting frame, and a placement frame is fixedly mounted on the other side of the processing table.

[0007] As a preferred embodiment of the wind tower longitudinal flange side leveling device of this utility model, the cylinder is aligned with the placement frame, and its piston rod extends toward the placement frame. In addition, the placement frame is provided with an adjustment column for adjusting the left and right positions.

[0008] As a preferred embodiment of the wind tower longitudinal flange side leveling device of this utility model, the guide is provided with a groove, which is used to place the longitudinal flange and observe whether the flange side is horizontal.

[0009] As a preferred embodiment of the wind tower longitudinal flange side leveling device of this utility model, the processing table is externally connected to an air hole control unit, which is used to control the working process of the cylinder.

[0010] As a preferred embodiment of the wind tower longitudinal flange side leveling device of this utility model, the leveling component and the guide are arranged at intervals, and the leveling component, the guide and the roller can be arranged in several groups according to the flange length.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting a guide with grooves, the horizontality of the flange side can be intuitively and reliably detected, which solves the shortcomings of traditional detection methods. At the same time, with the help of the aligned cylinder and the placement frame, and the precise control of the cylinder working process by the air hole control unit, the flange can be leveled efficiently and controllably, avoiding the drawbacks of manual leveling, effectively improving the connection accuracy of the longitudinal flange of the wind tower, and ensuring the stability and safety of the overall structure of the wind tower.

[0014] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Reference Figures 1-2A longitudinal flange side leveling device for wind turbines includes: a processing table 101, on which a guide 102 for guiding and supporting the flange is provided. The guide 102 has a groove for placing the longitudinal flange and observing whether the flange side is level. By observing the fit between the flange side and the groove's reference surface, the levelness of the flange side can be visually determined. The device is easy to operate and provides reliable test results. The processing table 101 also includes a leveling component 103 for leveling the flange. The leveling component 103 is used to level any non-level flanges detected. The device includes a mounting bracket 1031 fixedly mounted on a processing table 101, and a roller for sliding the flange to the next process. A cylinder 1032 is fixedly mounted on the mounting bracket 1031, and a placement bracket 1033 is fixedly mounted on the other side of the processing table 101. The cylinder 1032 is aligned with the placement bracket 1033, and its piston rod extends toward the placement bracket 1033. In addition, the placement bracket 1033 is provided with an adjusting column for adjusting the left and right positions. At the same time, an air hole control unit is externally connected to the processing table 101, which is used to control the working process of the cylinder 1032.

[0017] In addition, the leveling component 103 and the guide 102 are arranged at intervals, and the leveling component 103, the guide 102 and the roller can be set in several groups according to the flange length, so as to match the processing needs of flanges of different lengths.

[0018] In summary, the working process of this solution is as follows: When using this device, first place the longitudinal flange of the wind tower to be leveled into the groove of the guide 102, observe the fit between the flange side and the groove reference surface, and determine whether the flange side is level. If the flange side is found to be not level, remove the flange and place it on the placement frame 1033 of the leveling component 103, ensuring that the side of the flange to be leveled is aligned with the piston rod of the cylinder 1032. Start the cylinder 1032 through the air hole control unit, control the piston rod to extend towards the placement frame 1033, apply a predetermined thrust to the flange, and use the thrust to correct the tilt deformation of the flange. After leveling is completed, close the cylinder 1032, and move the flange to the next process by means of a roller. The roller is generally set between the guide 102 and the leveling component 103, parallel to the guide 102 and the leveling component 103, to facilitate the movement of long flanges. Generally, one roller is sufficient to ensure both easy movement and stability of long flanges. The adjusting column on the placement frame 1033 is used to drive the device to move horizontally and to adjust the left and right directions.

[0019] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0020] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
