Description

Technical Field

[0001] The utility model relates to the technical field of ring flange level detection, in particular to a wind turbine foundation ring flange level detection device. Background Art

[0002] Since the wind turbine resistor has a very large deadweight, in order to ensure the uniform distribution of the deadweight load, the tower and impeller rotating mechanism of the wind turbine need to operate in a horizontal position to ensure that the impeller is subjected to a uniform wind load. If the two end planes of the foundation ring flange are excessively uneven, when it is fixed to the foundation with fixing bolts, the entire device will be unevenly stressed, damaging the impeller structure or reducing the efficiency of wind energy utilization. Therefore, after the foundation ring flange is produced and processed, it is necessary to detect the horizontality of it. The existing detection device usually uses a spirit level to detect the foundation ring flange. Due to the large size of the foundation flange, it is not only necessary to repeatedly and tediously detect multiple times during the inspection, but the multiple detections cannot be connected, and the flatness of the overall flange cannot be accurately detected, affecting the actual detection results.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides Figure 1-3A wind turbine foundation ring flange horizontality detection device shown in the figure includes a cross bar 1 and an inclinometer 2 fixedly connected to the top of the cross bar 1, and leveling structures for adjusting the inclination of the cross bar 1 are arranged on both sides of the cross bar 1. The leveling structure includes a sliding sleeve 3, and the inner wall of the sliding sleeve 3 and the outer wall of the cross bar 1 are slidably connected and interlaced. One side of the sliding sleeve 3 is provided with a connecting rotating part, and one side of the connecting rotating part is provided with a supporting part for supporting and fixing the position of the cross bar 1.

[0018] It should be noted that the inclinometer 2 of the utility model adopts a digital inclinometer 2 of model QJY-JS01C. In actual use, corresponding leveling structures are set on both sides of the cross bar 1, and the sliding sleeve 3 is horizontally moved on the cross bar 1 to adapt to the foundation ring flanges of different diameters. After the support connected to the sliding sleeve 3 is stably placed on both sides of the foundation ring flange with the center of the circle as the center, the inclinometer 2 set in the middle of the top of the cross bar 1 is used to measure the overall horizontality of the foundation ring flange to avoid inaccurate test results caused by multiple tests.

[0019] The support member includes a supporting base plate 7, a supporting sleeve 6 is fixedly connected to the side of the top of the supporting base plate 7 close to the front, a threaded rod 5 is rotatably and interlacedly connected to the inner wall of the supporting sleeve 6, a rotating wheel 501 is fixedly connected to the top of the threaded rod 5, a limiting ring 502 is sleeved on the bottom end of the outer wall of the threaded rod 5, a limiting groove 601 is provided at the bottom end of the inner wall of the supporting sleeve 6, and the outer wall of the limiting ring 502 and the inner wall of the limiting groove 601 are rotatably and interlacedly connected.

[0020] Furthermore, the diameter of the rotating wheel 501 is larger than the diameter of the threaded rod 5, so when the rotating wheel 501 is rotated, the threaded rod 5 can be driven to rotate relatively easily, and the limiting ring 502 rotates in the limiting groove 601 to fix the position of the threaded rod 5 during rotation, thereby preventing the threaded rod 5 from falling off from the supporting sleeve 6 during rotation. It should be noted that the outer wall of the threaded rod 5 at the top of the supporting sleeve 6 is provided with threads, while the outer wall of the threaded rod 5 on the inner wall of the supporting sleeve 6 is a smooth surface.

[0021] The connecting rotating member comprises a rotating sleeve 301 , a side of the rotating sleeve 301 away from the threaded rod 5 is fixedly connected to one side of the sliding sleeve 3 , and a connecting rod 4 is rotatably inserted and connected to the inner wall of the rotating sleeve 301 .

[0022] A rotating ring 402 is sleeved on the outer wall of the connecting rod 4, a rotating groove 302 is opened on the inner wall of the rotating sleeve 301, and the inner wall of the rotating groove 302 and the outer wall of the rotating ring 402 are rotatably interlaced and connected.

[0023] A threaded sleeve 401 is fixedly connected to one side of the connecting rod 4 away from the rotating sleeve 301 , and the inner wall of the threaded sleeve 401 and the outer wall of the threaded rod 5 are threadedly interlaced.

[0024] Furthermore, the sliding sleeve 3 is connected to the threaded rod 5 through the connecting rod 4 and the threaded sleeve 401, and the threaded sleeve 401 is driven to adjust the position of the vertical plane along the threaded rod 5 by rotating the threaded rod 5. After the supporting base plate 7 is placed on the top of the base ring flange, the heights of the two sides of the cross bar 1 on the threaded rod 5 are adjusted by rotating the threaded rod 5. When the heights of the symmetrically arranged sliding sleeves 3 on the threaded rod 5 are the same, the plane levelness of the base ring flange can be obtained by the inclinometer 2 at the middle of the top of the cross bar 1. In actual use, the position of the connecting rod 4 is fixed by rotating the rotating ring 402 in the rotating groove 302, so as to avoid the connecting rod 4 falling off from the rotating sleeve 301 when adjusting the position of the threaded sleeve 401. At the same time, since the connecting rod 4 rotates in the rotating sleeve 301, when the cross bar 1 has an inclination, there will be no motion interference.

[0025] A pointer 403 is fixedly connected to the front of the threaded sleeve 401 , and a scale 8 is fixedly connected to one side of the top of the supporting base plate 7 .

[0026] In actual use, the position of the sliding sleeve 3 on the threaded rod 5 is controlled by the pointer 403 arranged on the threaded sleeve 401 pointing to the scale on the ruler 8 .

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
