[0003] The wind turbine tower is the tower of a wind power generation system. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. After the wind turbine tower is manufactured, it needs to be checked for roundness. If there are any problems, it needs to be rounded again. After the individual cylinder sections are welded, the roller frame is assembled and spot welded using a hydraulic assembly. After welding the inner and outer circumferential seams and checking the straightness and other tolerances, the flanges are welded. Then, the weld seams are non-destructive testing and flatness checks are performed.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] Please see Figure 1-5 This utility model provides a technical solution: a 180° rotating device for concrete wind turbine towers, comprising:

[0055] Support frame 1, the lower end of which is a rectangular frame base 11;

[0056] Support frame 1 has two symmetrically arranged on the left and right sides;

[0057] A positioning support structure 6 is assembled between the inner ends of the rectangular frame-shaped bases 11 on both sides;

[0058] A sleeve 13 is horizontally fixed at the upper end of the support frame 1;

[0059] The concrete wind turbine tower 2 has shafts 5 pre-embedded in the middle of its left and right side walls;

[0060] The shaft 5 is rotatably inserted into the sleeve 13 on the same side;

[0061] The upper and lower edges of the concrete wind turbine tower 2 are uniformly circumferentially embedded with internal threaded blocks 3;

[0062] The front and rear two internal threaded blocks 3 on the upper and lower edges of the concrete wind turbine tower 2 are each screwed with a first connecting lifting ring 4;

[0063] The upper and lower first connecting rings 4 are respectively connected to the hoisting ropes of the fixed external crane.

[0064] Specifically, in this embodiment, the main body of the rectangular frame base 11 is a rectangular frame made of I-beams, providing sufficient support area. The two side support frames 1 are symmetrically arranged to provide rotational support for the shafts 5 on both sides of the concrete wind turbine tower 2 through the sleeves 13 welded to the upper end. When the concrete wind turbine tower 2 is pulled and flipped by the external crane hoist, the shafts 5 rotate in the corresponding sleeves 13.

[0065] Furthermore, the concrete wind turbine tower 2 is suspended by the hoisting ropes of the external crane on the first connecting rings 4 at the upper and lower ends of the tower, providing tension to rotate the tower 2 180°. During the rotation, the two side support frames 1 provide stable support. A positioning support structure 6 is provided between the two side support frames 1 to connect the two side support frames 1 into a whole, increase the contact area with the ground, further improve the stability of the support, ensure the safety of construction, and at the same time, the placement position of the two side support frames 1 can be positioned.

[0066] More specifically; when performing the flipping operation of the concrete wind turbine tower 2, the concrete wind turbine tower 2 is initially set vertically. The lifting device located at the bottom applies an upward pulling force, while the lifting device located at the top does not apply a pulling force. The lower end of the concrete wind turbine tower 2 is slowly pulled up and flipped upward around the pivot point of the shaft 5 until the concrete wind turbine tower 2 flips 90 degrees to become horizontal. Both lifting devices on both sides provide support. Then, the lifting device originally located at the bottom continues to pull upward, causing the concrete wind turbine tower 2 to continue to flip 90 degrees, completing the 180° flip of the concrete wind turbine tower 2.

[0067] It is understandable that after the main body of the positioning support structure 6 is disassembled, the distance between the two side support frames 1 can be adjusted. Within a certain range, it is suitable for supporting different sizes of concrete wind turbine towers 2 during the flipping process. The main body of the positioning support structure 6 can be manufactured in several different length specifications according to the distance between the two side support frames 1, so as to achieve selective replacement of concrete wind turbine towers 2 of several applicable sizes.

[0068] Specifically, in this embodiment, the positioning support structure 6 includes:

[0069] There are two horizontal plates, 61, arranged parallel to each other front and back.

[0070] A connecting plate 63 is fixedly assembled between the front and rear cross plates 61;

[0071] The upper surface of the horizontal plate 61 has U-shaped frames 64 integrally formed at both the left and right ends, with their openings facing upwards;

[0072] The bottom surface of the frame at the inner end of the rectangular frame base 11 has a groove 62 corresponding to the U-shaped frame 64 on the same side;

[0073] The U-shaped frame 64 is inserted and snapped into the corresponding groove 62.

[0074] Specifically in this embodiment, the U-shaped frames 64 welded to the top surfaces of the front and rear horizontal plates 62 are inserted into the corresponding grooves 62 on the bottom side of the inner side of the rectangular frame base 11 to position the opposition of the two rectangular frame bases 11, and the bottom surface of the horizontal plates 62 is in contact with the ground to provide auxiliary support for the device.

[0075] Furthermore, a connecting plate 63 is provided between the front and rear horizontal plates 61 to connect the front and rear horizontal plates 61, which facilitates the positioning and assembly of the U-shaped frame 64 on multiple horizontal plates 61 and the rectangular frame-shaped bases 11 on both sides. The bottom surface of the connecting plate 63 is in contact with the ground for auxiliary support.

[0076] More specifically, the horizontal plate 61 is provided with sufficient length, and multiple pairs of U-shaped frames 64 can be welded on its surface to accommodate the dimensions of several applicable sizes of concrete wind turbine towers 2. When in use, the two side support frames 1 are lifted and assembled into the corresponding U-shaped frames 64 on the horizontal plate 61, eliminating the need to replace the positioning support structure 6 of different specifications.

[0077] It is understandable that the role of the positioning support structure 6 is to improve the support stability and assist in positioning the two side support frames 1. The main structure of the positioning support structure 6 is the structure other than the groove 62. The main structure of the positioning support structure 6 can be used or not. The device can still be used after removing the main structure of the positioning support structure 6. At this time, it is necessary to determine the placement position of the two side support frames 1 by measurement, and ensure the support stability by the weight of the support frame 1 itself, or to place counterweights on the support frame 1 to improve the support stability.

[0078] In some embodiments, the support frame 1 includes:

[0079] Tripod 12, the lower end of which is welded along the length of the rectangular frame base 11 to the middle of the top surface of the base;

[0080] Sleeve 13 is welded to the upper end of tripod 12;

[0081] The rectangular frame-shaped base 11 includes:

[0082] A rectangular frame 111 has a crossbeam 112 fixedly assembled along the width direction in the middle of its inner wall;

[0083] Tripod 12 includes:

[0084] The vertical plate 121 is vertically fixedly assembled to the middle of the top surface of the rectangular frame base 11;

[0085] A rectangular frame-shaped base 11 has inclined plates 122 symmetrically fixedly assembled on the middle of the front and rear sides of the top face, and the upper end of the inclined plates 122 is welded to the same side of the upper end of the outer wall of the vertical plate 121.

[0086] Sleeve 13 is welded to the upper end of vertical plate 121.

[0087] Specifically in this embodiment, the tripod 12 is triangular in shape on the plane, which improves stable support;

[0088] Furthermore, the crossbeam 112 improves the mechanical strength of the rectangular frame 111, while the crossbeam 112 provides a mounting and fixing position for the lower end of the vertical plate 121.

[0089] More specifically, the two inclined plates 122 are symmetrically supported on both sides of the lower end of the sleeve 13, and the vertical plate 121 is vertically supported in the middle of the lower end of the sleeve 13, forming a triangular stable support structure.

[0090] In some embodiments, a diagonal beam 15 is welded between the middle of the outer side of the top surface of the rectangular frame base 11 and the upper end of the outer wall of the vertical plate 121.

[0091] A connecting reinforcement structure 17 is installed between the upper end of the outer side of the inclined beam 15 and the outer wall of the sleeve 13.

[0092] The front and rear inclined plates 122 and the inclined beam 15 form a three-dimensional triangular frame.

[0093] Specifically, in this embodiment, the inclined beam 15 is used to distribute the force and improve the overall support stability of the support frame 1;

[0094] Furthermore, the front and rear inclined plates 122 and the inclined beam 15 form a three-dimensional triangular frame, which has stronger stability compared to a planar triangular frame.

[0095] In some embodiments, the rectangular frame base 11, vertical plate 121, inclined plate 122 and inclined beam 15 are all made of I-beams. I-beams, which are existing materials, are long strips of steel with an I-shaped cross-section, which improves the load-bearing capacity.

[0096] In some embodiments, the upper ends of the outer walls of the inclined plate 122 and the inclined beam 15 are each welded with a second connecting lifting ring 16 for connecting with the lifting device to facilitate the lifting operation of the support frame 1.

[0097] Specifically, in this embodiment, the connection reinforcement structure 17 includes:

[0098] A rectangular plate 171 is fitted and welded to the outer side of the outer wall of the sleeve 13;

[0099] The lower end of the rectangular plate 171 is integrally formed with an inclined reinforcing rib 172, which is welded to the upper end of the outer wall of the inclined beam 15.

[0100] In some embodiments, the rectangular plate 171 is welded and fixed to the outer wall of the sleeve 13, and the inclined reinforcing rib 172 is welded to the upper end of the outer wall of the inclined beam 15. The lower end of the rectangular plate 171 and the upper end of the inclined reinforcing rib 172 are integrally formed. This connection method connects the inclined beam 15 and the sleeve 13, directly distributing the force to the inclined beam 15, providing support strength for the sleeve 13, and better dispersing the force.

[0101] In some embodiments, a step 14 is uniformly welded to the lower end of the side wall of the rear inclined plate 122 along the length direction. The multi-level step 14 is used for stepping and climbing, which facilitates the installation and disassembly of the hoisting tools for the concrete wind turbine tower 2 and the support frame 1.

[0102] Furthermore, the outer wall of the pedal 14 can be covered with a rubber sleeve to prevent injury to the user's legs when stepping on it for climbing.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
