[0035] The beneficial effects of the present invention include: 1. The guiding part is installed at the top of the installed inclined tower segment. Through the guiding surface, it can guide the side wall of the to-be-installed inclined tower segment to slide down and adjust its posture so that it is located on the installed inclined tower segment, reducing the angular difference between the to-be-installed inclined tower segment and the target installation position. The displacement adjustment assembly can adjust the posture of the to-be-installed inclined tower segment, and further accurately position it to be adapted and installed on the installed inclined tower segment; the upper matching part and the lower matching part are respectively arranged on the installed inclined tower segment and the to-be-installed inclined tower segment, which can initially fixedly connect two adjacent inclined tower segments for subsequent construction; this alignment device can guide and position, solving the problem of greater installation difficulty for torsion-type inclined towers.

[0036] 2. The guiding part of the present invention has a simple structure. Through the inwardly inclined guiding surface, it can guide the to-be-installed inclined tower segment to slide down, and the positioning of the side wall of the to-be-installed inclined tower segment is more accurate when guiding it inside. Multiple positioning surfaces can abut against the side wall of the to-be-installed inclined tower segment for preliminary positioning, and even without using the displacement adjustment assembly to adjust the posture of the to-be-installed inclined tower segment, greatly improving the installation efficiency and being convenient to use.

[0037] 3. The guiding part is at least arranged on three side wall surfaces of the installed inclined tower segment, which can effectively correct the inclination angle of the to-be-installed inclined tower segment in the horizontal direction when guiding it to slide down, reduce or even eliminate the angular difference, and smoothly slide into the space between multiple positioning surfaces to achieve rapid installation.

The stiffness and stability of the lower matching part can be improved through the reinforcing rib plates.

[0040] 6. The displacement adjustment assembly supports and moves the upper displacement bracket on the lower displacement bracket through the three-way driving part, which can adjust the posture of the to-be-installed inclined tower segment to achieve accurate positioning.

[0041] 7. The lower displacement bracket has a simple structure. The lower support vertical plate installs the three-way driving part through the support flat plate at the top, and provides stiffness and stability through the support rib plates, enabling the three-way driving part to support and move the upper displacement bracket to adjust the posture of the to-be-installed inclined tower segment.

[0042] 8. The installation method of the present invention makes full use of the structural characteristics of the quick matching and alignment device provided by the present invention. Through multiple guiding members to guide the sliding of the to-be-installed inclined tower segment inside, and multiple positioning surfaces to conduct preliminary positioning on its side wall, the positioning accuracy is high, and even the adjustment by the adjustment component can be dispensed with, enabling the quick assembly of the to-be-installed inclined tower segment.

[0043] 9. Use a guy rope to tow the to-be-installed inclined tower segment to adjust its angular difference and inclination difference in the horizontal direction. Under the abutting and limiting of the positioning surface on its side wall, it is convenient for the to-be-installed inclined tower segment to slide smoothly onto the installed inclined tower segment in the expected posture, improving the accuracy of installation matching and alignment, and at the same time improving the installation efficiency.

[0044] 10. When there is an error in the to-be-installed inclined tower segment sitting on the installed inclined tower segment, the adjustment component can be used to adjust the posture of the to-be-installed inclined tower segment to achieve installation; by circumferentially and intermittently welding the adjacent two inclined tower segments through code plates, the adjacent two inclined tower segments can be strengthened and fixed, improving the connection strength.

[0045] The quick matching and alignment device for the torsion type steel inclined tower segment involved in the present invention can be used for matching, aligning and connecting the torsion type steel inclined tower segment. By guiding the sliding of the to-be-installed inclined tower segment through the guiding surface of the guiding member, the angular difference between the to-be-installed inclined tower segment and the target installation position can be reduced. The adjustment component can perform precise adjustment, and then the adjacent two inclined tower segments can be pre-fixed through the matching component, improving the installation efficiency and solving the problem of relatively large installation difficulty of the torsion type inclined tower.

[0060] The quick matching and alignment device for the torsional steel inclined tower segment involved in the present invention can be used for matching, aligning and connecting the torsional steel inclined tower segments. By guiding the sliding of the to-be-installed inclined tower segment 5 through the guiding surface 11 of the guiding member 1, the angular difference between the to-be-installed inclined tower segment 5 and the target installation position can be reduced. The positioning adjustment assembly 3 can perform precise positioning adjustment, and then the adjacent two inclined tower segments are pre-fixed by the matching assembly 2, which can improve the installation efficiency and solve the problem of the relatively large installation difficulty of the torsional inclined tower.

[0061] A quick matching and alignment device for the torsional steel inclined tower segment. Specifically, as Figures 1-9 shown, it includes a guiding member 1, a matching assembly 2 and a positioning adjustment assembly 3. The guiding member 1 is used to be fixedly arranged on the top side wall of the installed inclined tower segment 4 protruding from the end face of the installed inclined tower segment 4, and the guiding member is provided with a guiding surface 11 for guiding the side wall of the to-be-installed inclined tower segment 5 to slide onto the installed inclined tower segment 4; the matching assembly 2 includes a lower matching member 22 for being fixedly arranged on the top of the installed inclined tower segment 4 and an upper matching member 21 for being installed at the bottom of the to-be-installed inclined tower segment 5 to cooperate with the lower matching member 22 to fixedly connect the adjacent two inclined tower segments; the positioning adjustment assembly 3 is used to be arranged at the connection of the installed inclined tower segment 4 and the to-be-installed inclined tower segment 5 to adjust the posture of the to-be-installed inclined tower segment 5 to be adapted to be installed on the installed inclined tower segment 4, and the posture includes at least one of the spatial position of the to-be-installed inclined tower segment 5 relative to the target installation position, the angular difference around the axial direction, and the inclination angle in the horizontal direction. The guiding surfaces 11 of multiple guiding members 1 guide the multiple side walls of the to-be-installed inclined tower segment 5 to slide and adjust its posture so that it is seated on the installed inclined tower segment 4, reducing the angular difference between the to-be-installed inclined tower segment 5 and the target installation position. The positioning adjustment assembly 3 can adjust the posture of the to-be-installed inclined tower segment 5 and further perform precise positioning so that it is adapted to be installed on the installed inclined tower segment 4; the upper matching member 21 and the lower matching member 22 are respectively arranged on the installed inclined tower segment 4 and the to-be-installed inclined tower segment 5, and can initially fixedly connect the adjacent two inclined tower segments for subsequent construction.

[0062] In a certain embodiment, as Figure 1 and Figure 4As shown in the figure, the guiding member 1 is used to be fixedly arranged on the inner side of the side wall of the already installed inclined tower segment 4. The guiding member 1 includes a positioning surface 12 and a guiding surface 11. The positioning surface 12 is used to abut against the inner side of the side wall of the to-be-installed inclined tower segment 5 and limit the to-be-installed inclined tower segment 5 in the horizontal direction. The bottom end of the guiding surface 11 is connected to the positioning surface 12 and inclines inwards from bottom to top. In a specific solution, the guiding plate includes a lower rectangular plate and an upper trapezoidal plate. The hypotenuse of the trapezoidal plate faces outwards. The trapezoidal plate is preferably a right trapezoid and can be integrally formed with the rectangular plate. The guiding member 1 of the present invention has a simple structure. The inner sides of the side walls of the to-be-installed inclined tower segment 5 are guided to slide down through a plurality of guiding surfaces 11. A plurality of positioning surfaces 12 can abut against the side walls of the to-be-installed inclined tower segment 5 for preliminary positioning. Compared with guiding on the outside, guiding and positioning on the inside are more accurate, and even the attitude of the to-be-installed inclined tower segment 5 can be adjusted without using the positioning and adjusting component 3, greatly improving the installation efficiency and being convenient to use.

[0063] Based on the guiding member 1 including the positioning surface 12 and the guiding surface 11, as Figures 1-2 shown, the guiding member 1 is arranged on at least three side walls of the already installed inclined tower segment 4 to reduce the angular difference and inclination difference between the to-be-installed inclined tower segment 5 and the target installation position; preferably, the guiding member 1 is arranged on the inner side surfaces of the outer side walls of the already installed inclined tower segment 4 to better reduce or even eliminate the spatial position difference, angular difference and inclination difference between the to-be-installed inclined tower segment 5 and the target installation position, and further improve the guiding effect and positioning effect.

[0064] Based on the guiding member 1 including the positioning surface 12 and the guiding surface 11, as Figure 4 shown, the guiding member 1 is provided with a welding hole 13 located at the end face of the already installed inclined tower segment 4. After the to-be-installed inclined tower segment 5 is installed, the adjacent two inclined tower segments can be temporarily fixed by welding through the welding hole 13 at the connection seam.

[0065] In a certain embodiment, the matching component 2 is specifically described. As Figures 5-7 shown, the lower matching member 22 includes a lower connecting side plate 221, a lower mounting plate 222 and a lower reinforcing rib plate 223. The lower connecting side plate 221 is used to be fixedly connected to the side wall of the already installed inclined tower segment 4. The lower mounting plate 222 is fixedly connected to the top end of the lower connecting side plate 221. The two sides of the lower reinforcing rib plate 223 are respectively fixedly connected to the lower mounting plate 222 and the lower connecting side plate 221 to form a support. The structure of the lower matching member 22 is simple. The lower mounting plate 222 is used to support the upper matching member 21 of the to-be-installed inclined tower segment 5. The stiffness and stability of the lower matching member 22 can be improved through the lower reinforcing rib plate 223.

[0066] Based on the lower matching member 22 including the lower connecting side plate 221, the lower mounting plate 222 and the reinforcing rib plate, as Figures 5-6As shown, the upper matching member 21 includes an upper connecting side plate, an upper mounting plate, and upper reinforcing rib plates. The upper connecting side plate is used to be fixed on the side wall of the to-be-installed inclined tower segment 5. The upper mounting plate is fixedly connected to the bottom end of the upper connecting side plate. The two sides of the upper reinforcing rib plates are respectively fixedly connected to the upper mounting plate and the upper connecting side plate to form a support. When the to-be-installed inclined tower segment 5 is installed (accurately positioned) on the installed inclined tower segment 4, the upper matching member 21 can be correspondingly connected to the lower matching member 22, and the lower mounting plate 222 supports the upper mounting plate.

[0067] Based on the lower matching member 22 including a lower connecting side plate 221, a lower mounting plate 222, and a reinforcing rib plate, the lower mounting plate 222 is horizontally arranged. When supporting the upper mounting plate of the upper matching member 21, it can reduce the shear force with the upper matching member 21 and provide stability. Preferably, as Figures 6-7 shown, at least one perforation is provided on the lower mounting plate 222 for bolt connection with the upper matching member 21 through a bolt 23; the upper mounting plate is provided with a perforation corresponding to the lower mounting plate 222 for mutual bolt connection, which is convenient for quick fixation.

[0068] In a certain embodiment, the position adjustment assembly 3 is described. As Figure 1 、 Figure 3 and Figure 8 shown, the position adjustment assembly 3 includes a lower position adjustment bracket 32 for being fixedly arranged at the top end of the installed inclined tower segment 4, an upper position adjustment bracket 31 for being fixedly arranged at the bottom end of the to-be-installed inclined tower segment 5, and a three-way driving member 33 arranged between the lower position adjustment bracket 32 and the upper position adjustment bracket 31. The three-way driving member 33 is used to support and move the corresponding upper position adjustment bracket 31 on the lower position adjustment bracket 32. The three-way driving member 33 can be a three-way jack for adjusting the position of the to-be-installed inclined tower segment 5 in the horizontal, longitudinal, and vertical directions. In a more specific solution, the lower position adjustment bracket 32 is arranged at the connection of the wall plate and the web plate of the installed inclined tower segment 4, and the upper position adjustment bracket 31 is fixedly arranged on the to-be-installed inclined tower segment 5 corresponding to the lower position adjustment bracket 32, so that the three-way driving member 33 can support and move the upper position adjustment bracket 31, thereby adjusting the attitude of the to-be-installed inclined tower segment 5 to achieve accurate positioning.

[0069] Based on the position adjustment assembly 3 including the lower position adjustment bracket 32, as Figure 3 、 Figures 8-9As shown in the figure, the lower displacement bracket 32 includes a lower support vertical plate 321, a lower support flat plate 322 horizontally arranged and fixed on the top of the lower support vertical plate 321, and lower support rib plates 323 respectively fixed to the lower support vertical plate 321 and the lower support flat plate 322 on both sides. Preferably, the upper displacement bracket 31 is similar in structure to the lower displacement bracket 32. The upper displacement bracket 31 includes an upper support vertical plate, an upper support flat plate horizontally arranged and fixed at the bottom of the upper support vertical plate, and upper support rib plates respectively fixed to the upper support vertical plate and the upper support flat plate on both sides. The structure of the lower displacement bracket 32 is simple. The lower support vertical plate 321 installs the three-way drive member 33 through the support flat plate at the top, and provides stiffness and stability through the support rib plates, so that the three-way drive member 33 can support and move the upper displacement bracket 31 to adjust the attitude of the to-be-installed inclined tower segment 5, realizing precise positioning and installation. The upper support flat plate and the lower support flat plate 322 are both horizontally arranged, which can avoid the influence of shear force during the displacement adjustment process and facilitate the use of the three-way drive member 33 for displacement adjustment.

[0070] During actual use, a plurality of guide members 1 are fixed on the inner side wall surfaces of the outer side walls of each installed inclined tower segment 4, and welding holes 13 located at the end face of the installed inclined tower segment 4 are provided on the guide members 1; a plurality of lower displacement brackets 32 are fixed on the wall plates at the top of the installed inclined tower segment 4 at the connection with the web, a three-way jack is arranged on the lower displacement bracket 32, and an upper displacement bracket 31 is arranged on the to-be-installed inclined tower segment 5 corresponding to the lower displacement bracket 32; a plurality of lower matching members 22 are fixed on the plurality of side walls of the installed inclined tower segment 4; an upper matching member 21 is arranged on the to-be-installed inclined tower segment 5 corresponding to the lower matching member 22 for fixed connection to perform final positioning and pre-fixing on the to-be-installed inclined tower segment 5.

During the sliding process, the posture of the to-be-installed inclined tower segment 5 is gradually adjusted. A plurality of positioning surfaces 12 limit the inner side wall surface of the outer peripheral side wall of the to-be-installed inclined tower segment 5 inside, which can correct the spatial position and angular difference, with high positioning accuracy. Even without using the position adjustment component 3 to adjust the position of the to-be-installed inclined tower segment 5, it is convenient for quick installation.
