[0002] A wind turbine truss tower is a spatial truss structure composed of members connected by nodes. It is used to support wind turbine generators and features lightweight, high strength, and good wind resistance.

[0003] However, during the assembly process of traditional wind turbine truss towers, the lack of flexible and effective guidance and locking mechanisms often requires a lot of time and manpower for frequent adjustments of the truss tower columns, resulting in extremely low overall assembly efficiency. Secondly, the traditional wind turbine truss tower assembly method cannot ensure the verticality and concentricity of the truss tower columns during assembly. The lack of effective structures to stabilize and correct the column positions during the assembly process results in large assembly errors, which cannot meet the construction requirements of high-quality wind turbine truss towers.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figures 1-5 As shown, this utility model proposes an auxiliary assembly tooling for wind turbine truss towers. It includes a pair of mounting frames 1, with several rolling support frames 2 arranged between the two mounting frames 1. The rolling support frames 2 are used to support the assembly and alignment steel cylinders 3, providing them with a placement platform, and cooperate with the guide components 4 to guide the assembly and alignment steel cylinders 3 to move horizontally. A pair of assembly and alignment steel cylinders 3 are arranged on the several rolling support frames 2. The assembly and alignment steel cylinders 3 are used to correct and fix the truss tower columns 6, ensuring the verticality and concentricity of the truss tower columns 6 during assembly, and reducing assembly errors. At the same time, the assembly and alignment steel cylinders 3 adopt a design that combines straight cylinders and conical cylinders, which not only ensures assembly accuracy but also does not affect the placement and adjustment of the lower flange of the truss tower columns 6. Guide components 4 are arranged between the two assembly and alignment steel cylinders 3 and the rolling support frames 2, and locking components 5 are arranged between the two assembly and alignment steel cylinders 3. The truss tower columns 6 are inserted between the two assembly and alignment steel cylinders 3.

[0023] The guide assembly 4 includes rolling support seats 43 on both sides of the bottom of the assembly and alignment steel cylinder 3. The rolling support seats 43 provide the mounting base for the screw 44 and the roller 45. Each rolling support seat 43 is provided with a screw 44 through it. The screw 44 connects the rolling support seat 43 and the roller 45 and transmits the force during movement. One end of the screw 44 is provided with a roller 45. Several connecting plates 42 are provided between each two adjacent rolling support frames 2. Each rolling support frame 2 is provided with a guide rail 41 at the position corresponding to the roller 45. The roller 45 rolls on the guide rail 41 to guide the assembly and alignment steel cylinder 3 to move horizontally in a specified direction. The end of the screw 44 away from the roller 45 is provided with a high-strength locking nut 46. When the high-strength locking nut 46 is tightened, it can lock the assembly and alignment steel cylinder 3 to prevent it from moving. Conversely, when it is loosened, it allows the assembly and alignment steel cylinder 3 to move.

[0024] Each assembled and corrected steel cylinder 3 is equipped with a rolling support seat 2 47 at its bottom. The rolling support seat 2 47 provides an installation base for the roller 2 48. Several rollers 2 48 are installed at the bottom of the rolling support seat 2. The rollers 2 48 roll on the rolling support frame 2, which helps the assembled and corrected steel cylinder 3 to move smoothly.

[0025] Several inner stiffening plates 410 are provided on the inner wall of the assembled and straightened steel cylinder 3, and several outer stiffening plates 49 are provided on the outer wall of the assembled and straightened steel cylinder 3. The inner stiffening plates 410 and the outer stiffening plates 49 can enhance the structural strength of the assembled and straightened steel cylinder 3, enabling it to better bear the load.

[0026] The locking assembly 5 includes assembly locking seats 51 disposed on both sides of the top of the assembly and alignment steel cylinder 3. The assembly locking seats 51 provide installation positions for the assembly high-strength bolts 52. Several assembly high-strength bolts 52 are disposed between two adjacent assembly locking seats 51 on the same side. Each assembly high-strength bolt 52 is provided with an assembly high-strength nut 53. The combined use of the assembly high-strength bolts 52 and the assembly high-strength nuts 53 connects and tightens the two assembly and alignment steel cylinders 3, ensuring that the connection is firm and reliable.

[0027] Working Principle: Before assembling the truss tower column 6, the position of the assembly and alignment steel cylinder 3 needs to be adjusted. First, loosen the high-strength locking nut 46 on the outer side of the rolling support seat 43 to make the assembly and alignment steel cylinder 3 movable. Then, move the two assembly and alignment steel cylinders 3 to their maximum adjustment range along the rolling support frame 2 to both sides. During this process, the roller 45 on the rolling support seat 43 moves along the guide rail 41, and the roller 48 on the bottom rolling support seat 47 of the assembly and alignment steel cylinder 3 moves along the rolling support frame 2 located in the middle. The two rollers work together to stabilize and support the upper assembly and alignment steel cylinder 3 and assist its movement. At this time, the two assembly and alignment steel cylinders... With cylinder 3 in a separated state, sufficient space is left for placing the main column of the truss tower. Then, the main column of the truss tower is slowly lowered. When the lower flange of the truss tower column 6 is placed a certain distance below the straight section of the assembly and correction steel cylinder 3, the assembly and correction steel cylinders 3 on both sides are moved towards the center along the rolling support frame 2. Similarly, roller 1 45 and roller 2 48 move along the guide rail 41 and the rolling support frame 2 located in the middle, respectively, to ensure the smoothness of the movement process until the two assembly and correction steel cylinders 3 are put together. At this time, the high-strength locking nut 46 on the outside of the rolling support seat 1 43 is tightened inward to lock the position of the two assembly and correction steel cylinders 3 and prevent them from moving again.

[0028] After the position is locked, the two assembled and straightened steel cylinders 3 are further tightened using the locking assembly 5. The assembled and straightened steel cylinders 3 are connected and tightened together by the high-strength bolts 52 and high-strength nuts 53 on the assembly locking seat 51, ensuring that the connection is firm and reliable. At the same time, the inner stiffening plates 410 and outer stiffening plates 49 set on the inner and outer walls of the assembled and straightened steel cylinders 3 can enhance their structural strength and enable them to better bear the load. After the assembled and straightened steel cylinders 3 on both sides are locked and fixed, the truss tower column 6 is placed downwards. In the subsequent assembly process, the assembled and straightened steel cylinders 3 can play a key role in ensuring the overall verticality and concentricity of the truss tower column 6 and minimizing the overall assembly error. Moreover, the assembled and straightened steel cylinders 3 adopt a design that combines straight cylinders and conical cylinders. While ensuring the assembly accuracy of the truss tower column 6, it will not affect the placement and adjustment of the lower flange of the truss tower column 6, providing a strong guarantee for the assembly of the entire wind power truss tower.
