The assembling tool provided by the embodiment of the invention is used for assembling more than two tower barrel segments 100. As shown in FIG. 1, each tower section 100 may be arcuate and have opposite first and second ends 101 and 102, respectively, in the direction M, with each tower section 100 extending along an arcuate path and having two free ends in the direction of extension.

Referring to fig. 1 to 3, in an implementation, the central rod 11 of the first position adjustment assembly 10 may be a circular cylindrical structure, which may be solid, or may be a hollow cylindrical structure. The horizontal adjustment rods 121 extend in the radial direction of the center stay 11, and the configuration of the first position adjustment assembly 10 can be simplified and the processing can be facilitated. Meanwhile, each horizontal adjusting rod 121 is limited to extend along the radial direction of the central support rod 11, so that when the horizontal adjusting rods 121 are supported on the corresponding tower section pieces 100, the tower section pieces 100 can be stressed more uniformly, and under the condition that the same supporting force is applied to the tower section pieces 100, when the horizontal adjusting rods 121 are stressed in the arrangement mode, the moment is smaller, and the service life of the first position adjusting assembly 10 and even the whole assembly tool can be prolonged.

Further, the horizontal adjustment rods 121 are uniformly arranged in the circumferential direction Y of the center pole 11. When the first position adjusting assembly 10 supports more than two tower sections 100, the first position adjusting assembly 10 is more uniformly stressed, so that the adjusting precision and the adjusting efficiency of the opening angle of the first end portion 101 and the second end portion 102 of each tower section 100 in the circumferential direction Y are ensured, and the assembling precision and the assembling efficiency between two adjacent tower sections 100 are further improved.

Referring to fig. 5 and 6 together, fig. 5 is a schematic structural diagram of a leveling rod 121 according to an embodiment of the present invention, and fig. 6 is an enlarged view of a point a in fig. 5. In order to better satisfy the requirement that at least one horizontal adjustment rod 121 of the two horizontal adjustment rods 121 in the same group is retractable in the extending direction thereof, so as to further satisfy the requirement for adjusting the first end 101 of the tower segment 100, the horizontal adjustment rod 121 provided in the embodiment of the present invention includes a first rod 1211 and a second rod 1212, which are sleeved with each other, the first rod 1211 is connected to the central support rod 11, the second rod 1212 is capable of moving relative to the first rod 1211 along the axial direction of the first rod 1211, and a dimension measuring device 15 is disposed on the first rod 1211 to feed back the length of the second rod 1212 extending out of the first rod 1211. The length of the corresponding horizontal adjusting rod 121 can be adjusted more accurately according to the requirement of the opening angle of the tower drum segment 100 to be assembled, and therefore the assembling precision and the assembling efficiency of the tower drum segment 100 are improved.

With reference to fig. 5 and fig. 6, in some alternative examples, the first rod 1211 of the horizontal adjustment rod 121 is provided with an avoiding groove 1211a extending along its own axial direction, the avoiding groove 1211a penetrates through a sidewall of the first rod 1211, and the dimension measuring device 15 is a scale marked along the axial direction of the first rod 1211 and is disposed on a wall surface surrounding the avoiding groove 1211 a.

With the above arrangement, when the second rod 1212 slides relative to the first rod 1211, the pointer 1212b can move along with the second rod 1212 relative to the scale mark to feed back the moving distance of the second rod 1212 relative to the first rod 1211, so that the entire horizontal adjustment rod 121 reaches a predetermined length.

Referring to fig. 7 and 8 together, fig. 7 is a schematic structural view illustrating a leveling rod 121 according to another embodiment of the present invention, and fig. 8 is an enlarged view of a portion B in fig. 7.

With the above arrangement, when the second rod 1212 rotates relative to the first rod 1211 and extends out of the first rod 1211 in the axial direction of the first rod 1211, since the pointer 1212b and the small-diameter section of the second rod 1212 are connected by the second bearing 1213, the pointer 1212b may not rotate relative to the first rod 1211, and the pointer 1212b is prevented from being peeled off or the relative rotation between the first rod 1211 and the second rod 1212 is restricted when the first rod 1211 and the second rod 1212 rotate relative to each other. Meanwhile, the second bearing 1213 is fixedly connected to the small diameter section of the second rod 1212, so that when the second rod 1212 moves relative to the first rod 1211, the second bearing 1213 can drive the pointer 1212b to move relative to the scale mark, and the moving distance of the second rod 1212 relative to the first rod 1211 can also be fed back, so that the entire horizontal adjustment rod 121 reaches a predetermined length.
