[0046] Next, we will refer to Figures 1 to 17 The various parts of the positioning device for assembling tower segments in this example embodiment are described in more detail.

[0047] It should be noted that during the assembly operation at the construction site, the tower segment 100 located at the bottom of the single-leg tower 10 needs to be precisely assembled on the foundation 20, which is the foundation 20 described in the present embodiment. In the present embodiment, the steel pipe block 101 of the tower segment 100 is positioned and assembled on the foundation 20 by positioning the support pedestal 300; and the other tower segments 100 of the single-leg tower 10 need to be spliced ​​and assembled in sequence from the bottom of the tower to the top of the tower along the axis of the single-leg tower 10 at the construction site.

[0048] It should also be noted that the tower segment 100 may include four steel pipe blocks 101 and four steel shell blocks 102, wherein the four steel pipe blocks 101 are located at the four corners of the tower segment 100, and along the circumferential direction of the tower segment 100, the steel pipe blocks 101 and the steel shell blocks 102 are alternately arranged.

[0049] It should also be noted that, based on the structural characteristics of the cable tower in this embodiment, that is, the cable tower is a steel tube steel shell combined cable tower, each cable tower segment 100 of the cable tower is composed of a steel tube block 101 and a steel shell block 102. In the structure of the cable tower segment 100, the steel tube blocks 101 at the four corners have high rigidity and high matching accuracy requirements, so the positioning device for cable tower segment assembly construction of the present application is used to achieve precision control of the steel tube blocks 101, which can ensure the assembly accuracy of the steel cable tower segment 100, thereby improving the overall assembly accuracy of the steel tube steel shell combined cable tower.

[0050] In one embodiment, reference Figures 2 to 4 As shown in the figure, the leveling mechanism 200 includes anchor bolts 202 and a leveling embedded steel plate 201. The anchor bolts 202 are embedded in the foundation 20. The leveling embedded steel plate 201 is adjustably arranged on the foundation 20 through the anchor bolts 202. The base plate 301 is placed on the leveling embedded steel plate 201 and is detachably connected to the leveling embedded steel plate 201 through the anchor bolts 202. By adjusting the leveling embedded steel plate 201, the positioning support pedestal 300 placed on the leveling embedded steel plate 201 is leveled. After the positioning support pedestal 300 is leveled, the positioning support pedestal 300 is fastened and connected to the leveling embedded steel plate 201 through the anchor bolts 202, thereby realizing the leveling and positioning assembly of the positioning support pedestal 300 on the foundation 20.

[0051] Optional, reference Figure 4 and Figure 5 As shown in , a plurality of anchor bolts 202 are pre-embedded on the foundation 20, and the plurality of anchor bolts 202 are distributed in a circular pattern on the foundation 20, and a plurality of connection holes 3011 are provided on the base plate 301, and the plurality of connection holes 3011 are located outside the annular support plate 302 and arranged at intervals along the circumference of the annular support plate 302, and each anchor bolt 202 is correspondingly penetrated in a connection hole 3011. By pre-embedding a plurality of anchor bolts 202 on the foundation 20, and opening a plurality of connection holes 3011 on the base plate 301, the base plate 301 is firmly and balancedly connected to the leveling pre-embedded steel plate 201, and the positioning support pedestal 300 is ensured to be firmly assembled on the foundation 20, which is conducive to ensuring the accuracy of the subsequent docking and assembly of the steel pipe block 101 using the positioning support pedestal 300.

[0052] In one embodiment, reference Figure 5 and Figure 6As shown in , a positioning reference plate 304 is provided on the base plate 301, and the positioning reference plate 304 is located on the inner side of the annular support plate 302, and is used to align and position the steel pipe block 101 in the circumferential direction of the steel pipe block 101. The positioning reference plate 304 is used to align and position the steel pipe block 101 in the circumferential direction of the steel pipe block 101, so as to control the assembly accuracy of the steel pipe block 101.

[0053] Optional, reference Figure 5 As shown in the figure, the base plate 301 is provided with a first stiffening plate 305 and a second stiffening plate 306 intersecting each other, the first stiffening plate 305 and the second stiffening plate 306 are located on the inner side of the annular support plate 302, and the positioning reference plate 304 is provided on the first stiffening plate 305 and the second stiffening plate 306. The first stiffening plate 305 and the second stiffening plate 306 can improve the supporting strength of the positioning support pedestal 300 to the steel pipe block 101, and can also provide reliable support for the positioning reference plate 304.

[0054] For further reference, Figure 5 and Figure 6 As shown in , a first positioning line P1 and a second positioning line P2 are arranged vertically and intersectingly on the surface of the positioning reference plate 304. The first positioning line P1 and the second positioning line P2 extend radially along the annular support plate 302 respectively, and are used to align and position the steel pipe block 101 in the circumferential direction of the steel pipe block 101. It should be noted that the first positioning line P1 and the second positioning line P2 on the positioning reference plate 304 need to cooperate with the reference lines arranged on the steel pipe block 101 to achieve more accurate positioning of the steel pipe block 101.

[0055] Example, reference Figure 7 and Figure 8 As shown in , the tube wall of the steel tube block 101 is provided with a plurality of first longitudinal baselines S1 and a plurality of second longitudinal baselines S2 extending along the axial direction thereof, the projections of the plurality of first longitudinal baselines S1 on the radial section of the steel tube block 101 are A1, A2, B1, B2 respectively, the projections of the plurality of second longitudinal baselines S2 on the radial section of the steel tube block 101 are C1, C2, D1, D2, and the connecting line of the projections A1, A2, B1, B2 is perpendicular to and intersects with the connecting line of the projections C1, C2, D1, D2. Based on this, by aligning the line connecting the projections A1, A2, B1, and B2 with the first longitudinal baseline S1, and aligning the line connecting the projections C1, C2, D1, and D2 with the second longitudinal baseline S2, or aligning the line connecting the projections C1, C2, D1, and D2 with the first longitudinal baseline S1, and aligning the line connecting the projections A1, A2, B1, and B2 with the second longitudinal baseline S2, more accurate positioning of the steel pipe block 101 can be achieved.

[0056] In one embodiment, the intersection of the first positioning line P1 and the second positioning line P2 is the positioning point. It should be noted that when assembling the multiple steel pipe blocks 101 of the tower segment 100, multiple positioning support pedestals 300 are required, that is, each positioning support pedestal 300 quickly positions a corresponding steel pipe block 101, but at the same time, it is also necessary to control the positioning accuracy of the multiple steel pipe blocks 101 of the tower segment 100, which can be achieved with the help of multiple positioning support pedestals 300 cooperating with each other. Specifically, when the positioning support pedestal 300 is leveled with the help of the leveling embedded steel plate 201, the positions of the multiple positioning support pedestals 300 can be adjusted first until the positioning points of the positioning reference plates 304 on the multiple positioning support pedestals 300 are at the same elevation, and then the positioning support pedestals 300 and the leveling embedded steel plate 201 are locked and fixed.

[0057] In one embodiment, reference Figures 9 to 12 As shown in , the positioning matching component 400 includes a joint plate 401 and a splicing plate 402. The joint plate 401 is arranged on the steel pipe block 101 and can be processed and assembled on the steel pipe block 101 in the factory; the splicing plate 402 is used to connect the matching joint plate 303 and the joint plate 401, and the splicing plate 402 is detachably connected with the matching joint plate 303 and the joint plate 401, and the splicing plate 402 can be assembled on the construction site. The aligned joint plate 401 and the matching joint plate 303 are connected by the splicing plate 402, so that the steel pipe block 101 and the positioning support base 300 are accurately docked and fixed.

[0058] It should be noted that the operation process of using the joint plate 401, the splicing plate 402 and the matching joint plate 303 at the construction site to achieve precise docking and fixing of the steel pipe block and the positioning support base 300 is as follows: using a rivet to connect a part of the splicing plate 402 with the matching joint plate 303; aligning each joint plate 401 with a corresponding matching joint plate 303; using a rivet to connect the other part of the splicing plate 402 with the joint plate 401; using bolts to fasten the joint plate 401 and the matching joint plate 303 to the splicing plate 402 respectively.

[0059] In one embodiment, see Figures 9 to 11 As shown in the figure, the positioning matching component 400 can be composed of two joint plates 401 and two splicing plates 402. The two joint plates 401 can be respectively arranged at the upper interface and the lower interface position of the steel pipe block. During assembly, the two splicing plates 402 can be arranged on both sides of the joint plate 401.

[0060] It should be noted that, for the tower segment 100 located at the bottom of the single-leg cable tower 10 and precisely assembled on the foundation 20, the joint plate 401 at the lower interface of the steel pipe block 101 of the tower segment 100 can be cooperated with the splicing plate 402 to be used for docking with the matching joint plate 303 of the positioning support pedestal 300, thereby realizing the connection between the steel pipe block 101 and the positioning support pedestal 300, and the joint plate 401 at the upper interface of the steel pipe block 101 of the tower segment 100 can be cooperated with the splicing plate 402 to be used for docking with the joint plate 401 of another steel pipe block 101, thereby realizing the connection between the two steel pipe blocks 101 arranged along the axial direction of the single-leg cable tower 10.

[0061] It should be noted that, for the tower segment 100 located in the middle section of the tower body of the single-leg cable tower 10, the joint plate 401 at the lower interface of the steel pipe block 101 of the tower segment 100 can be cooperated with the splicing plate 402 to be used for docking with the joint plate 401 of the lower steel pipe block 101, thereby realizing the connection between the two steel pipe blocks 101 arranged along the axial direction of the single-leg cable tower 10, and the joint plate 401 at the upper interface of the steel pipe block 101 of the tower segment 100 can be cooperated with the splicing plate 402 to be used for docking with the joint plate 401 of the upper steel pipe block 101, thereby realizing the connection between the two steel pipe blocks 101 arranged along the axial direction of the single-leg cable tower 10.

[0062] Optional, see Fig.11 As shown in the figure, a plurality of first holes 4011 are provided on the joint plate 401, and a plurality of second holes 4021 are provided on the splicing plate 402. When the steel pipe block 101 is hoisted at the construction site, some of the first holes 4011 on the joint plate 401 can be used as hoisting holes. When the steel pipe block 101 is assembled onto the positioning support pedestal 300, the first holes 4011 on the joint plate 401 are used for rivets or bolts to pass through, and the second holes 4021 on the splicing plate 402 are used for rivets or bolts to pass through, so as to fasten the joint plate 401 and the matching joint plate 303 to the splicing plate 402 respectively.

[0063] Optional, reference Figure 5 As shown in the figure, a plurality of through holes 3031 are provided through the matching joint plate 303, and the plurality of through holes 3031 are arranged at intervals along the axial direction of the annular support plate 302 for the penetration of rivets or bolts to achieve fastening of the matching joint plate 303 and the splicing plate 402.

[0064] It should be noted that, according to the above description, through the positioning device for the assembly construction of the tower segment of the present application, the assembly accuracy control of the steel pipe block 101 is converted to the high-precision connection between the positioning matching component 400 and the positioning support pedestal 300. At the same time, the accuracy of the positioning matching component 400 also ensures the positioning accuracy of the assembly of the tower segment 100.

[0065] In one embodiment, reference Fig.13 As shown in , the positioning connection assembly 500 includes a plurality of positioning channel steels 501, and the plurality of positioning channel steels 501 are used to fix a plurality of steel pipe blocks in the circumferential direction of the cable tower segment 100. The plurality of steel pipe blocks 101 of the cable tower segment 100 can be positioned circumferentially by the positioning channel steels 501, so as to achieve precision control of the upper interface of the steel pipe blocks 101.

[0066] It should be noted that the operation of temporarily fixing the multiple steel pipe blocks of the tower segment 100 using multiple positioning channel steels 501 at the construction site is as follows: in the circumferential direction of the tower segment 100, two adjacent steel pipe blocks 101 are connected by a corresponding positioning channel steel 501, and the connection between the positioning channel steel 501 and the steel pipe block 101 is close to the upper interface of the steel pipe block 101.

[0067] For further reference, Fig.13 As shown in , the positioning connection assembly 500 also includes a plurality of tie strands 502, which are used to connect two steel pipe blocks arranged in a diagonal direction of the cable tower segment 100. On the basis that the positioning channel steel 501 can perform circumferential positioning on the plurality of steel pipe blocks 101 of the cable tower segment 100, the tie strands 502 are used for fine adjustment to assist in coordination, so as to achieve fine adjustment of the interface size on the cable tower segment 100, which is not only fast in operation but also high in precision.

[0068] It should be noted that the operation of further fixing the multiple steel pipe blocks of the tower segment 100 using multiple tie wires 502 at the construction site is as follows: in the diagonal direction of the tower segment 100, the two steel pipe blocks 101 arranged along the diagonal direction are tightened by the tie wires 502, and the connection between the tie wires 502 and the steel pipe blocks 101 is close to the upper interface of the steel pipe blocks 101.

[0069] It should also be noted that the reference Fig.13 and Fig.14 As shown in , the positioning channel steel 501 and the steel pipe block 101 are connected by L-shaped angle steel 503, and can be connected by bolting, which is easy to operate and reliable.

[0070] It should also be noted that when laying the tie wires 502, the length of the tie wires 502 can be adjusted and corrected synchronously by measuring the diagonal dimensions of the four corners of the interface on the tower segment 100, thereby achieving precise auxiliary adjustment, wherein the diagonal dimension is the distance between the two steel pipe blocks 101 arranged in the diagonal direction of the tower segment 100.

[0071] Optionally, the tension strands 502 may be steel strands.

[0072] It should also be noted that the reference Fig.15 As shown in the figure, with the help of the positioning channel steel 501 and the tension wire 502 of the positioning connection assembly 500, it is also convenient to accurately install the annular stiffening plate 103 of the tower segment 100, that is, after the upper interface of the steel pipe block 101 is positioned and fixed by using the positioning channel steel 501 and the tension wire 502, the multiple corner segments 1031 of the annular stiffening plate 103 are first connected to the multiple steel pipe blocks 101 one by one, and then each connecting segment 1032 of the annular stiffening plate 103 is correspondingly installed between the two corner segments 1031 along the circumference of the tower segment 100.
