Description

Technical Field

[0001] The utility model relates to the field of wind power generation tower production, in particular to a tooling which is convenient for stacking slice-type towers. Background Art

[0002] In a wind turbine generator set, the tower is used to support the generator set. The greater the power of the generator set, the larger the diameter of the tower will be. However, when the diameter of the tower is too large, it will be restricted by the width of some roads and the height of the bridge door openings, as well as the height limit frame during transportation. In order to solve this problem, the prior art has introduced a segmented tower, that is, each tower section is divided into three or four tower sections for transportation, and then assembled into a complete tower section on site, and then multiple tower sections are stacked and installed as a whole. When loading multiple tower sections for transportation, in order to prevent the displacement of the tower sections, the multiple tower sections must be stacked and fixed. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a tooling which is convenient for stacking segmented tower tubes.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a tooling that is convenient for stacking segmented towers, comprising a plurality of reinforcement plates, each of which is composed of a left section, a middle section, and a right section connected in sequence, the middle section being a horizontal section, and the left section and the right section being inclined upward relative to the middle section, so that a large trapezoidal groove is formed on the upper part of the entire reinforcement plate, and a plurality of through holes are provided at the outer ends of the left section and the right section, so that a plurality of reinforcement plates can be stacked through the large trapezoidal groove.

[0005] When in use, a reinforcement plate is installed on the flanges at both ends of each tower segment, the multiple through holes on the left and right sections of the reinforcement plate are aligned with the through holes on the flange and then fixed with bolts, and then the multiple tower segments installed with reinforcement plates are stacked up and down, and the large trapezoidal grooves of the reinforcement plates are nested layer by layer. This can prevent the tower segments from being displaced due to vibration or inertia during transportation.

[0006] Furthermore, a small trapezoidal groove opposite to the large trapezoidal groove is provided at the lower part of the middle section of the reinforcement plate.

[0007] Furthermore, a trapezoidal boss having a shape matching the small trapezoidal groove is provided on the upper part of the middle section of the reinforcing plate, so that the two reinforcing plates can be embedded through the small trapezoidal groove and the trapezoidal boss, and the stability between the upper and lower reinforcing plates can be further enhanced.

[0008] In one embodiment, multiple reinforcement plates are stacked, including the first reinforcement plate, the second reinforcement plate, and the third reinforcement plate from bottom to top, and the spacing between the left section through holes and the right section through holes of the three reinforcement plates gradually decreases from bottom to top.

[0009] In one embodiment, the reinforcing plate is cut from a steel plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0017] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In the description of the present utility model, it should be noted that, unless otherwise specified and defined, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two elements, it can be a direct connection, or it can be an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meaning of the terms can be understood according to the specific circumstances.

[0019] like Figure 1 , 2As shown, the preferred embodiment of the utility model is: a tooling for facilitating the stacking of segmented towers, comprising a plurality of reinforcing plates cut from steel plates, each of which is formed by connecting a left section 1, a middle section 2, and a right section 3 in sequence, the middle section 2 being a horizontal section, the left section 1 and the right section 3 are both inclined upward relative to the middle section 2, so that a large trapezoidal groove 4 is formed on the upper part of the entire reinforcing plate, a small trapezoidal groove 5 opposite to the large trapezoidal groove 4 is provided at the lower part of the middle section 2 of the reinforcing plate, a trapezoidal boss 6 whose shape matches the small trapezoidal groove 5 is provided at the upper part of the middle section 2 of the reinforcing plate, a plurality of through holes 7 are provided at the outer ends of the left section 1 and the right section 3, a plurality of reinforcing plates can be stacked through the large trapezoidal groove 4, and the small trapezoidal groove 5 and the trapezoidal boss 6 are interlocked, which can further enhance the stability between the upper and lower reinforcing plates.
