[0023] In actual use, first, the upper clamping plate 7 and the lower clamping plate 8 are spliced ​​together at one end of the steel pipe tower 1. After the splicing is completed, the upper positioning plate 3 and the lower positioning plate 4 are also spliced ​​together. Then, the groups of screw holes 6 on the surface of the flange base 2 are aligned with the groups of positioning columns 5 on the surfaces of the upper positioning plate 3 and the lower positioning plate 4. Then, the flange base 2 is sleeved on one end of the steel pipe tower 1, and the positioning columns 5 are also inserted into the screw holes 6. Finally, the end of the flange base 2 away from the upper positioning plate 3 is aligned with the pipe mouth of the steel pipe tower 1. Since the circular sheet structure composed of the upper clamping plate 7 and the lower clamping plate 8 and the upper positioning plate 3 and the lower positioning plate 4 are coaxial with the steel pipe tower 1, the positioning is performed through the positioning columns 5 and the screw holes 6. The flange base 2 in position is also coaxial with the steel pipe tower 1, so the positioning of the flange base 2 can be completed, and then the steel pipe tower 1 and the flange base 2 are welded. After welding, the upper clamping plate 7 and the lower clamping plate 8 can be separated to remove the positioning assembly. When welding the flange base 2 of a large number of steel pipe towers 1, it is only necessary to splice the upper clamping plate 7 and the lower clamping plate 8 on each group of steel pipe towers 1 in turn and align the screw holes 6 of each group of flange bases 2 with the positioning column 5 and sleeve them on the flange base 2, and then align the end of the flange base 2 away from the upper positioning plate 3 with the port of the steel pipe tower 1, so as to quickly complete the positioning, thereby improving the efficiency of batch welding of flange bases 2 for a large number of steel pipe towers 1.

[0024] Embodiment 2

[0025] On the basis of the first embodiment, in order to prevent the upper clamping plate 7 and the lower clamping plate 8 from moving around along the axis of the steel pipe tower 1, anti-skid grooves 10 are provided on the inner ring surfaces of the upper clamping plate 7 and the lower clamping plate 8, and anti-skid pads 11 are provided in the anti-skid grooves 10.

[0026] An anti-skid groove 10 is opened on the inner ring of the upper clamping plate 7 and the lower clamping plate 8, and an anti-skid pad 11 is arranged in the anti-skid groove 10. When the upper clamping plate 7 and the lower clamping plate 8 are spliced ​​on the surface of the steel pipe tower 1, the anti-skid pad 11 is pressed tightly. At the same time, the anti-skid pad 11 is made of rubber, so that there is a large friction between the anti-skid pad 11 and the steel pipe tower 1. This friction can prevent the upper clamping plate 7 and the lower clamping plate 8 from running around along the axis of the steel pipe tower 1.

[0027] Embodiment 3

[0032] When the upper splint 7 and the lower splint 8 are to be spliced, the block 15 is first fully pressed into the block groove 14. The movement of the block 15 compresses the block spring 16. Then the splicing rod 13 at the bottom end of the upper splint 7 is inserted into the splicing hole 12 on the surface of the lower splint 8. When the splicing rod 13 extends from the other end of the splicing hole 12, the block spring 16 pushes one end of the block 15 out of the block groove 14 under its own elastic action.

Finally, the end of the flange base 2 away from the upper positioning plate 3 is aligned with the pipe mouth of the steel pipe tower 1. Since the circular sheet structure composed of the upper clamping plate 7 and the lower clamping plate 8 and the upper positioning plate 3 and the lower positioning plate 4 are coaxial with the steel pipe tower 1, the positioning columns are used to The flange base 2 positioned by the screw hole 5 and the screw hole 6 is also coaxial with the steel pipe tower 1, so the positioning of the flange base 2 can be completed, and then the steel pipe tower 1 and the flange base 2 are welded. After welding, the upper clamping plate 7 and the lower clamping plate 8 can be separated to remove the positioning assembly. When welding the flange base 2 of a large number of steel pipe towers 1, it is only necessary to splice the upper clamping plate 7 and the lower clamping plate 8 on each group of steel pipe towers 1 in turn and align the screw holes 6 of each group of flange bases 2 with the positioning column 5 and sleeve them on the flange base 2, and then align the end of the flange base 2 away from the upper positioning plate 3 with the port of the steel pipe tower 1, so that the positioning can be completed quickly, which improves the efficiency of welding a large number of steel pipe towers. 1 improves the efficiency of batch welding of flange base 2; anti-skid grooves 10 are provided on the inner rings of upper clamping plates 7 and lower clamping plates 8, and anti-skid pads 11 are provided in the anti-skid grooves 10.

This friction can prevent upper clamping plates 7 and lower clamping plates 8 from running around along the axis of steel pipe tower 1; gripping rods 9 are fixed on the surfaces of upper clamping plates 7 and lower clamping plates 8, so as to facilitate gripping of upper clamping plates 7 and lower clamping plates 8; to splice upper clamping plates 7 and lower clamping plates 8 When the upper and lower plates 7 and 8 are to be separated, the block 15 is fully pressed into the block groove 14 again, and the movement of the block 15 compresses the block spring 16, and then the splicing rod 13 at the bottom end of the upper splint 7 is inserted into the splicing hole 12 on the surface of the lower splint 8. When the splicing rod 13 extends from the other end of the splicing hole 12, the block spring 16 pushes one end of the block 15 out of the block groove 14 under its own elastic action, and the block 15 is stuck on the boss surface of the lower splint 8 to complete the splicing. When the upper and lower plates 7 and 8 are to be separated, the block 15 is fully pressed into the block groove 14 again, and the splicing rod 13 can be pulled out from the splicing hole 12 to complete the separation of the upper and lower plates 7 and 8.
