[0002] The wind turbine tower is the tower of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. The production process of wind turbine tower is generally as follows: CNC cutting machine unloads, thick plates need to be beveled, plate rolling machine rolls the plate into shape, spot welding, positioning, and confirmation before welding the inner and outer longitudinal seams. After the roundness check, if there is a problem, a second rounding is performed. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, the weld is non-destructively tested and the flatness is checked. After sandblasting and painting, the internal parts are installed and the finished product is inspected, and then it is transported to the installation site.

[0003] In the process of the above processing, it is inevitable to design the turning over of the tower. The traditional turning over method is to directly lift the tower by a crane and then turn the tower over. This process requires welding lifting ears on the tower in advance to facilitate the lifting of the crane. After the tower is turned over, the lifting ears on the surface of the tower also need to be removed. The whole process is very troublesome. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tower turning tool which is convenient for turning over the tower.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a tower turning tool, the innovation of which is: comprising:

[0006] A turning bracket, comprising a turning main bracket and turning side brackets connected to both sides of the turning main bracket;

[0007] The turning main bracket is a rectangular tube, and a first lifting ear is connected to the middle of the turning main bracket, a first lifting hole is opened on the first lifting ear, and the first lifting ear is located at the side end of the turning main bracket;

[0008] The turning side bracket comprises a second ear plate arranged vertically and an auxiliary fixing plate arranged horizontally, wherein the second ear plate and the auxiliary fixing plate are connected together to form an L-shaped structure, a second hanging hole is opened at the upper position of the second ear plate, and a plurality of first lashing holes distributed in parallel are opened on the auxiliary fixing plate, and the central axis of the first lashing hole and the central axis of the second hanging hole are perpendicular to each other;

[0009] A pair of parallel reinforcing plates are connected between the second ear plate and the auxiliary fixing plate, and a second binding hole is opened between the reinforcing plate and the second ear plate. The central axis of the second binding hole is perpendicular to the central axis of the first binding hole, and the central axis of the second binding hole is perpendicular to the central axis of the second hanging hole.

[0010] Furthermore, a plurality of sleepers are arranged on the bottom surface of the turning-over side bracket, and the sleepers are fixed to the auxiliary fixing plate by means of binding belts passing through the first binding holes.

[0011] The advantages of the utility model are: the tower turning tool of the utility model lifts the tower through the cooperation of the turning main bracket and the turning side bracket, and there is no need to weld lifting ears on the tower, which facilitates the lifting; in addition, through the different distributions of the first binding holes and the second binding holes, different positions of the tower are bound, which facilitates the stable fixation of the tower and provides a good foundation for the subsequent turning of the tower, and the first lifting hole is set at the side end of the turning main bracket instead of directly at the upper end of the turning main bracket. In this way, the first lifting hole and the second lifting hole are misaligned, so that after the subsequent lifting, the turning tool can be easily rotated through the cooperation of the first lifting hole to facilitate the adjustment of the position of the tower.

[0012] The design of the sleepers on the bottom surface of the turning side bracket serves to provide a barrier and protection for the turning side bracket and the tower. Since both the turning side bracket and the tower are made of metal, sleepers are used to avoid contact and friction between the two, which may lead to scratches and other damages on the surface of the tower. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0014] Figure 1 It is a schematic diagram of the tower turning tool of the utility model.

[0015] Figure 2 It is a top view of the tower turning tool of the utility model. Implementation

[0016] The following embodiments may enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.

[0017] like Figure 1 , Figure 2 A tower turning tool as shown includes:

[0018] A turning bracket comprises a turning main bracket 1 and turning side brackets connected to both sides of the turning main bracket 1.

[0019] The turning main bracket 1 is a rectangular hollow tube, and a first lifting ear 11 is connected to the middle position of the turning main bracket 1. The first lifting ear 11 is directly welded and fixed to the turning main bracket 1. A first lifting hole 12 is opened on the first lifting ear 11. The first lifting ear 11 is located at the side end of the turning main bracket 1, and the relative first lifting hole 12 is also located outside the vertical plane where the central axis of the turning main bracket 1 is located.

[0020] The turning side bracket includes a second ear plate 2 arranged vertically and an auxiliary fixing plate 21 arranged horizontally, wherein the second ear plate 2 and the auxiliary fixing plate 21 are connected together to form an L-shaped structure, a second lifting hole is opened at the upper position of the second ear plate 2, and the second lifting hole is located on the vertical plane where the central axis of the turning main bracket 1 is located. The first lifting hole 12 is set at the side end of the turning main bracket 1, rather than directly at the upper end of the turning main bracket 1. In this way, the first lifting hole 12 is misaligned with the second lifting hole, so that after subsequent lifting, the turning tooling can be easily rotated through the cooperation of the first lifting hole to facilitate the adjustment of the position of the tower.

[0021] Several first binding holes 25 distributed in parallel are opened on the auxiliary fixing plate 21, and the central axis of the first binding hole 25 is perpendicular to the central axis of the second hanging hole. There are two types of first binding holes 25, namely, waist-shaped holes located on both outer sides of the auxiliary fixing plate 21 and a circular hole located in the middle of the auxiliary fixing plate 21.

[0022] A pair of parallel reinforcement plates 22 are connected between the second ear plate 2 and the auxiliary fixing plate 21, and a second lashing hole 24 is opened between the reinforcement plate 22 and the second ear plate 2. The central axis of the second lashing hole 24 is perpendicular to the central axis of the first lashing hole 25, and the central axis of the second lashing hole 24 is perpendicular to the central axis of the second hanging hole. The different distributions of the first lashing holes 25 and the second lashing holes 24 allow lashing at different positions of the tower, making it convenient to stably fix the tower, and providing a good foundation for the subsequent turning of the tower.

[0023] A plurality of sleepers 23 are also arranged on the bottom surface of the turning side bracket. The sleepers 23 are long wooden blocks, and the sleepers 23 are fixed to the auxiliary fixing plate 21 by means of a strap passing through the first binding hole 25. The design of the sleepers 23 on the bottom surface of the turning side bracket plays a role of barrier protection between the turning side bracket and the tower. Since the turning side bracket and the tower are both made of metal, the sleepers 23 are used to avoid contact between the two and friction between them, thereby causing scratches and other damages on the surface of the tower.

[0024] When using the tower turning tool of the utility model to turn over the tower, firstly, the entire tower turning tool is hoisted to the top of the tower that needs to be turned over by a crane, the tower turning tool is installed on the upper end surface of the tower, and the sleepers 23 are supported on the tower, and then, the tower is fixed to the turning side bracket by passing the binding belt through the first binding hole 25 and the second binding hole 24, and then the steel wire rope of the crane is passed through the first lifting hole 12 and the second lifting hole to lift the tower so that the tower is suspended in the air, and then the tower is turned over by different lifting of the two second lifting holes, and then the steel wire rope is used to pull the first lifting hole 12 to drive the entire tower turning tool to rotate, and the position of the tower is adjusted until the turning of the tower is completed. In the above-mentioned turning process, there is no need to weld lifting ears on the tower, which facilitates lifting.
