Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure wind towers, and particularly relates to a steel structure wind tower frame which is convenient to assemble. Background Technique

[0002] As an important part of wind power generation equipment, the steel structure wind tower frame is mainly used to support the wind turbine and enable it to operate stably at high altitudes. With the continuous development and popularization of wind power generation technology, the performance requirements for the steel structure wind tower frame are also getting higher and higher.

[0003] At present, most traditional steel structure wind tower frames adopt an integral design. Although this design method ensures the structural strength and stability of the wind tower frame to a certain extent, there are also some obvious disadvantages:

[0004] Firstly, the integral-designed wind tower frame is huge in volume and heavy in weight, which brings great difficulties to transportation and installation. Special transportation equipment and lifting tools are required, increasing costs and risks. Secondly, when the steel structure wind tower frame is stressed, it is prone to bending or deformation.

[0005] Therefore, it is very necessary to invent a steel structure wind tower frame that is convenient to assemble. Content of the Utility Model

[0006] The purpose of the utility model is to provide a steel structure wind tower frame that is convenient to assemble and solve the problems mentioned in the background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a steel structure wind tower frame that is convenient to assemble, including an assembly frame, a reinforcing frame, insertion columns, connecting pieces and a support frame. A plurality of assembly frames are provided, and the assembly frames are arranged vertically up and down. A plurality of connecting pieces are fixed between adjacent assembly frames by bolts. A plurality of reinforcing frames are fixed inside the assembly frames by welding, and support frames are arranged in the middle of the assembly frames. The output ends of the support frames are fixed to the corresponding reinforcing frames. A plurality of insertion columns are fixed to the upper and lower ends of the assembly frames by welding, and the insertion columns are slidably installed inside the corresponding connecting pieces.

[0009] Furthermore, the connecting member includes a sleeve, a top plate, a bottom plate, and reinforcing ribs. The upper end of the sleeve is fixedly welded with a top plate, and the top plate is fixed to the upper assembly frame by bolts; the lower end of the sleeve is fixedly welded with a bottom plate, and the bottom plate is fixed to the lower assembly frame by bolts; several reinforcing ribs are fixedly welded to the outer side surface of the sleeve; corresponding insertion columns are slidably arranged inside the sleeve, the top plate, and the bottom plate. Such a setting facilitates the assembly of the assembly frame during use, and can avoid the deviation of the assembly frame during assembly.

[0010] Furthermore, the total height of the sleeve, the top plate, and the bottom plate is equal to the total length of the two insertion columns. Such a setting enables the corresponding insertion columns on the upper assembly frame and the lower assembly frame to fully enter the connecting member, and there will be no cavity inside the connecting member.

[0011] Furthermore, the support frame includes a cross, inclined columns, mounting plates, and limit blocks. Several inclined columns are fixedly welded inside the cross, and the output ends of the cross are all fixed with mounting plates by bolts; limit blocks adapted to the strengthening frame are fixedly welded to the outer side surface of the mounting plates, and the limit blocks are buckled on the outer side surface of the middle part of the corresponding strengthening frame. Such a setting can strengthen the structural strength of the strengthening frame.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] The present utility model adopts an assembled structure, splitting the originally large and difficult-to-transport steel structure wind tower frame into several relatively small assembly frames. Such a design reduces the transportation difficulty and cost of individual components. When installation is required, the assembly frames can be assembled together through the connecting member; secondly, due to the setting of the support frame, through the tight buckling of the limit blocks and the strengthening frame, the strengthening frame is effectively prevented from bending or deforming when stressed, thus ensuring the overall safety and reliability of the wind tower frame.

[0022] In the description of the present utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.

[0023] Please refer to Figure 1 and Figure 2 As shown, the present utility model is a steel structure wind tower frame convenient for assembly, including an assembly frame 1, a reinforcement frame 2, an insertion column 3, a connecting member 4, and a support frame 5. There are several assembly frames 1, and the assembly frames 1 are arranged vertically up and down, and several connecting members 4 are fixed between adjacent assembly frames 1 by bolts; several reinforcement frames 2 are fixedly welded inside the assembly frames 1, and support frames 5 are arranged in the middle of the assembly frames 1, and the output ends of the support frames 5 are fixed to the corresponding reinforcement frames 2; several insertion columns 3 are fixedly welded at the upper and lower ends of the assembly frames 1, and the insertion columns 3 are all slidably installed inside the corresponding connecting members 4.

[0024] As Figure 3As shown in the figure, the connecting member 4 includes a sleeve 41, a top plate 42, a bottom plate 43 and a reinforcing rib 44. The upper end of the sleeve 41 is fixedly welded with the top plate 42, and the top plate 42 is fixed to the upper assembly frame 1 by bolts; the lower end of the sleeve 41 is fixedly welded with the bottom plate 43, and the bottom plate 43 is fixed to the lower assembly frame 1 by bolts; several reinforcing ribs 44 are fixedly welded to the outer side surface of the sleeve 41; corresponding insertion columns 3 are slidably arranged inside the sleeve 41, the top plate 42 and the bottom plate 43. After the lower assembly frame is fixed, the connecting member 4 can be slidably installed on the insertion column 3 at the upper end of the corresponding lower assembly frame 1, and the bottom plate 43 is fixed to the lower assembly frame 1 by bolts. Then, the insertion column 3 at the lower end of the upper assembly frame 1 is slidably inserted into the corresponding connecting member 4, and the top plate 42 is fixed to the upper assembly frame 1 by bolts, so as to complete the up-and-down splicing and assembly of the assembly frame 1. Among them, during the assembly process, due to the corresponding settings of the positions of the connecting member 4 and the insertion column 3, it is possible to avoid the position deviation between the upper assembly frame 1 and the lower assembly frame 1 when splicing the assembly frame 1.

[0025] Specifically, the total height of the sleeve 41, the top plate 42 and the bottom plate 43 is equal to the total length of the two insertion columns 3.

[0026] As Figure 4 shown in the figure, the support frame 5 includes a cross 51, inclined columns 52, mounting plates 53 and limiting blocks 54. Several inclined columns 52 are fixedly welded inside the cross 51, and the output ends of the cross 51 are all fixed with mounting plates 53 by bolts; limiting blocks 54 adapted to the reinforcing frame 2 are fixedly welded to the outer side surface of the mounting plates 53, and the limiting blocks 54 are buckled on the outer side surface of the middle part of the corresponding reinforcing frame 2. After the assembly frame 1 is fixed, the support frame 5 can be arranged inside the assembly frame 1, and the limiting blocks 54 are connected to the reinforcing frames 2 at different positions, so as to strengthen the structural strength of the reinforcing frame 2 and prevent the reinforcing frame 2 from bending.

[0027] Please refer to Figures 1-4 shown in the figure. The utility model relates to a steel structure wind tower frame which is convenient for assembly, and its working principle is: during installation, a plurality of assembly frames 1 can be assembled up and down together through the connecting member 4, and the support frame 5 is used to support the reinforcing frame 2 inside the assembly frame 1, so as to prevent the reinforcing frame 2 from bending.
