Description

Technical Field

[0001] This utility model belongs to the technical field of concentricity measurement devices, specifically relating to a device for measuring the concentricity of concrete segments installed in wind turbine towers. Background Technology

[0002] In the installation of prefabricated concrete wind turbine towers, measuring the concentricity of circular concrete segments is crucial for ensuring uniform structural stress and reducing additional stress. Concentricity typically refers to the deviation of the centers of adjacent segments (or adjacent sections), requiring precise measurement using specialized equipment and scientific methods. In the installation of circular segments in hybrid wind turbine towers, the accuracy of concentricity measurement directly impacts the overall stability and safety of the tower structure. As the wind power industry develops towards larger diameters and greater heights (such as 190-meter-class hybrid tower projects), traditional measurement methods are insufficient to meet the dual demands of millimeter-level accuracy and the complex high-altitude environment. This is especially true for offshore wind power, which further increases the requirements for installation precision.

[0003] Therefore, there is an urgent need to provide a device for measuring the concentricity of concrete segments installed in wind turbine towers to solve the above problems. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a device for measuring the concentricity of concrete segments installed in wind turbine towers. Precise concentricity control helps reduce the risk of accidents in mixed tower structures and ensures the safety of operation and maintenance personnel.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a device for measuring the concentricity of concrete segments installed in wind turbine towers, comprising: an annular support frame, on which two sets of measuring mechanisms are arranged side by side along the axial direction. Each measuring mechanism includes multiple measuring components arranged circumferentially around the axis of the annular support frame. Each measuring component includes a slide rod that is slidably connected to the annular support frame radially. A roller is rotatably connected to the end of the slide rod extending to the inner side of the annular support frame. A baffle is fixedly connected to the end of the slide rod extending to the outer side of the annular support frame. A spring is fixedly connected between the baffle and the outer wall of the annular support frame. A displacement sensor for detecting the distance between the baffle and the annular support frame is installed on the baffle.

[0007] Furthermore, the annular support frame is provided with slide grooves corresponding to the slide rods one by one, and the slide rods are slidably connected in the slide grooves. The annular support frame is provided with an annular groove that communicates with all the slide grooves in the same set of measuring mechanisms. An annular limiting frame that can slide along the axial direction of the annular groove is provided in the annular groove. The slide rod is provided with toothed grooves, and the annular limiting frame is provided with toothed blocks that mesh with the toothed grooves one by one. Sliding the annular limiting frame causes the toothed blocks to mesh with or disengage from the toothed grooves, thereby locking or unlocking the slide rod.

[0008] Furthermore, the annular limiting frame is rotatably connected to a threaded ring coaxially arranged with the side wall away from the toothed groove. The threaded ring is threadedly connected to the annular support frame, and rotating the threaded ring can cause the annular limiting frame to move axially along the annular support frame.

[0009] Furthermore, a toothed ring coaxially arranged with the threaded ring is fixedly connected to the side of the threaded ring away from the annular limiting frame, and a gear meshing with the toothed ring is rotatably connected inside the annular support frame, wherein the height of the toothed ring is greater than the height of the gear.

[0010] Furthermore, a drive mechanism for driving the gear rotation is fixedly installed on the annular support frame.

[0011] Furthermore, at least two gears are provided, and multiple gears are arranged circumferentially around the axis of the annular support frame.

[0012] Furthermore, the gears are provided in three parts.

[0013] The beneficial effects of this utility model are as follows: by observing whether the difference between two displacement sensors in the same vertical direction is consistent, it is possible to measure the concentricity of adjacent concrete slab segments, which helps to reduce the risk of accidents in mixed tower structures and ensure the safety of operation and maintenance personnel.

[0014] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0019] like Figures 1-2 As shown, this utility model provides a device for measuring the concentricity of concrete segments installed in a wind turbine tower, comprising: an annular support frame 1, on which two sets of measuring mechanisms are arranged side by side along the axial direction; each measuring mechanism includes multiple measuring components 2 arranged circumferentially around the axis of the annular support frame 1; each measuring component includes a slide rod 201 slidably connected to the annular support frame 1 radially; a roller 202 is rotatably connected to the end of the slide rod 201 extending to the inner side of the annular support frame 1; a baffle 203 is fixedly connected to the end of the slide rod 201 extending to the outer side of the annular support frame 1; a spring 204 is fixedly connected between the baffle 203 and the outer wall of the annular support frame 1; and a displacement sensor (not shown in the figure) for detecting the distance between the baffle 203 and the annular support frame 1 is installed on the baffle 203.

[0020] In this scheme, the concentricity measuring device is used to measure the concentricity of the concrete segments 3 during the installation of the wind turbine tower. Before the annular support frame 1 is fitted onto the concrete segments 3, the baffle 203 is located on the same circumferential surface under the action of the spring 204. After the annular support frame 1 is fitted onto the concrete segments 3, the two sets of measuring mechanisms are moved to correspond to two adjacent concrete segments 3 respectively. Under the action of the spring 204, the roller 202 is kept in contact with the inner wall of the concrete segments 3. Since the wind turbine tower is set in a frustum shape, the measuring device located on the upper part of the two sets of measuring mechanisms... In the measuring mechanism, multiple rollers 202 arranged circumferentially abut against the outer wall of the upper concrete segment 3, and in the measuring mechanism below, multiple rollers 202 arranged circumferentially abut against the outer wall of the lower concrete segment 3. If the values ​​detected by each displacement sensor in the same set of measuring mechanisms are consistent (or within the preset error range), it indicates that the circumference of the concrete segment 3 meets the requirements. If the difference between the values ​​detected by two displacement sensors located on the same axis in the two sets of measuring mechanisms is consistent (or within the preset error range), it indicates that the two concrete segments 3 are concentrically arranged.

[0021] This solution can measure the concentricity of adjacent concrete slab segments by observing whether the difference between two displacement sensors in the same vertical direction is consistent. This helps reduce the risk of accidents in the mixed tower structure and ensures the safety of operation and maintenance personnel.

[0022] In one embodiment of this utility model, the annular support frame 1 is provided with a sliding groove 101 corresponding to the sliding rod 201. The sliding rod 201 is slidably connected in the sliding groove 101. The annular support frame 1 is provided with an annular groove 102 that communicates with all the sliding grooves 101 in the same group of measuring mechanisms. An annular limiting frame 4 that can slide along the axial direction of the annular groove 102 is provided in the annular groove 102. The sliding rod 201 is provided with a toothed groove 205. The annular limiting frame 4 is provided with toothed blocks 401 that mesh with the toothed grooves 205. Sliding the annular limiting frame 4 causes the toothed blocks 401 to mesh with or disengage from the toothed grooves 205, thereby locking or unlocking the sliding rod 201.

[0023] In this scheme, during the installation of the wind turbine tower, in the initial state, the toothed block 401 on the annular limiting frame 4 is disengaged from the toothed groove 205. During the installation of the wind turbine tower, the annular support frame 1 is moved so that the two sets of measuring mechanisms correspond to the two adjacent concrete segments 3 respectively. Then, the annular limiting frame 4 is driven to move closer to the sliding rod 201 so that the toothed block 401 engages with the toothed groove 205. At this time, the sliding rod 201 is locked and cannot slide along the sliding groove 101. Since the wind turbine tower is set in a frustum shape, it can prevent the annular support frame 1 from moving downward, thereby ensuring the stability of the annular support frame 1 and improving the accuracy of concentricity measurement.

[0024] In one embodiment of this utility model, a threaded ring 5, coaxially arranged with the side wall of the annular limiting frame 4 away from the toothed groove 205, is rotatably connected to the annular limiting frame 4. The threaded ring 5 is threadedly connected to the annular support frame 1. Rotating the threaded ring 5 allows the annular limiting frame 4 to move axially along the annular support frame 1, thereby improving the stability of the annular limiting frame 4 when moving to a preset position.

[0025] In one embodiment of this utility model, a toothed ring 6 coaxially arranged with the threaded ring 5 is fixedly connected to the side of the threaded ring 5 away from the annular limiting frame 4, and a gear 7 that meshes with the toothed ring 6 is rotatably connected inside the annular support frame 1, and the height of the toothed ring 6 is greater than the height of the gear 7.

[0026] In this scheme, the drive gear 7 rotates to make the gear ring 6 rotate, thereby making the threaded ring 5 rotate to drive the annular limit frame 4 to move axially.

[0027] In one embodiment of this utility model, a drive mechanism for driving the gear 7 to rotate is fixedly installed on the annular support frame 1. The drive mechanism is a drive motor 8 for outputting rotational power. The motor model is adapted to the size of the annular support frame 1 by those skilled in the art, and will not be described in detail here.

[0028] In one embodiment of this utility model, at least two gears 7 are provided, and multiple gears 7 are arranged circumferentially around the axis of the annular support frame 1. In this solution, three gears 7 are provided, and each gear 7 is fixedly connected to a driving mechanism to ensure that the center of gravity of the annular support frame 1 is the center of the annular support frame 1, and to avoid the annular support frame 1 tilting, which would cause errors in the concentricity measurement.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
