DETAILED DESCRIPTION

[0039] The following will be combined with the attached embodiment of the present invention Figure 1-8 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] (like Figure 8 The method for manufacturing a steel arch tower vertical hinge structure as shown in the figure comprises the following steps:

[0041] (like Figure 1 (as shown) Step S001, cutting and processing of vertical hinge components: cutting and processing the components of the upper vertical hinge 6 and the lower vertical hinge 5 according to size: the vertical hinge components include the stiffening plate 1, the partition plate 2 and the bearing plate 3.

[0042] (like Figure 2 (as shown) Step S002, production of the bearing plate unit 4: welding the stiffening plate 1 and the bearing plate 3 together to produce the bearing plate unit 4; the bearing plate unit 4 includes an upper bearing plate unit 401 and a lower bearing plate unit 402.

[0043] Among them, a plurality of stiffening plates 1 are welded and fixedly installed on the outer side of the bearing plate 3; the plurality of stiffening plates 1 are cross-intersected, and according to the height of the bearing plate, there can be a plurality of cross-intersecting stiffening plates 1.

[0044] (like Figure 3Step S003, positioning and assembling the bearing plate unit 4 on one side: placing the lower bearing plate unit 402 of the lower vertical hinge 5 on the lower side, and placing the upper bearing plate unit 401 of the upper vertical hinge 6 on the upper side; aligning the positions of the pin holes 403 of the lower bearing plate unit 402 and the upper bearing plate unit 401. That is, the horizontal assembly method is adopted to reduce the difficulty of assembly.

[0045] (like Figure 4 (as shown) Step S004, assembly of partitions: assembling the partitions 2 on the lower bearing plate unit 402 and the upper bearing plate unit 401.

[0046] (like Figure 5 Step S005, positioning and assembling the bearing plate unit 4 on the other side: assemble the bearing plate unit 4 on the symmetrical side of the partition 2 on the other side of the partition 2. Place the lower bearing plate unit 402 of the lower vertical hinge 5 in the bearing plate unit 4 on the symmetrical side of the partition 2 on the upper side; place the upper bearing plate unit 401 of the upper vertical hinge 6 on the lower side; align the positions of the pin shaft holes 403 of the upper bearing plate unit 401 and the lower bearing plate unit 402 on the symmetrical side of the partition 2 to obtain the vertical hinge pre-assembly.

[0047] It can be seen that: first assemble the bearing plate unit 4 on one side, then position and assemble the bearing plate unit 4 on the other side, this order ensures the matching accuracy of the partition 2 and the bearing plate unit 4. After assembly, mark the positioning to provide a reference line for welding after disassembly in the subsequent steps.

[0048] Step S006, disassembly and trimming: disassemble the pre-assembled vertical hinge obtained in step S005, weld and trim it according to the positioning line after disassembly.

[0053] It can be seen that the use of special positioning tooling to pre-assemble the vertical hinge structure of the steel arch tower effectively ensures that the vertical hinge structure of the steel arch tower forms a continuous curve; and makes the width of the outer web unit of the upper steel arch tower segment 8 and the lower steel arch tower segment 7 change in a quadratic parabola along the central axis of the steel arch tower.

[0054] (Combined Figure 6 ) Step S009, disassembly and finishing: disassemble the pre-assembled parts of the vertical hinge structure of the steel arch tower obtained in step S008, weld them according to the pre-assembly positioning line and finish them.

[0056] The present invention proposes to first weld the load-bearing plates and partitions of the upper and lower vertical hinges into a whole; then machine the pin shaft holes respectively; the vertical hinge structure of the steel arch tower adopts a "horizontal assembly method": that is, the outer web unit, the top plate unit, and the bottom plate unit of the steel arch tower segment are assembled in sequence, and then the vertical hinge structure, the temporary positioning pin shaft and the inner web unit are assembled in the steel arch tower segment to form a box-shaped structure; then the vertical hinge structure of the steel arch tower is disassembled, and welding and trimming are performed; finally, a manufacturing process and method of reassembling the temporary positioning pin shaft and performing a secondary reset trial rotation are adopted to complete the simulated rotation of the vertical hinge structure of the steel arch tower in the factory, so as to provide a guarantee for the overall vertical rotation of the steel arch tower at the bridge position.

[0057] In the above embodiment, further: in step S001, the height deviation of the partition plate 2 during machining is less than or equal to 0.5 mm. In the above embodiment, further: in step S007, the pin hole 403 is machined by a boring machine, and the concentricity deviation of the pin hole 403 is less than 0.2 mm.

[0061] In the above embodiment, further: the upper vertical hinge 6 and the upper steel arch tower segment 8; the lower vertical hinge 5 and the lower steel arch tower segment 7; the assembly of the upper vertical hinge 6 and the lower vertical hinge 5 are all assembled using special positioning tooling; the special positioning tooling includes an angle template and a positioning line; the angle template and the positioning line are used to accurately adjust and control the linear shape of the steel arch tower vertical hinge structure.

[0062] (Combined Figure 6 ) Among them, with the help of special positioning tooling, the alignment of the vertical hinge structure of the steel arch tower is precisely adjusted and controlled: the angles of the upper vertical hinge 6 and the upper steel arch tower segment 8, the lower vertical hinge 5 and the lower steel arch tower segment 7, and the continuous arc alignment of the upper steel arch tower segment 8 and the lower steel arch tower segment 7 are perfectly matched. It can be seen that the use of special positioning tooling to pre-assemble the vertical hinge structure of the steel arch tower effectively ensures the formation of a continuous curve.

[0063] (like Figure 7 As shown in the figure, the upper vertical hinge 6 and the lower vertical hinge 5 are respectively provided with a pin hole 403; the positioning pin passes through the pin hole 403 to hinge the upper steel arch tower segment 8 and the lower steel arch tower segment 7 together.

[0064] (See Figure 6 ) The connected upper steel arch tower segment 8 and the lower steel arch tower segment 7 form a continuous curve; and the width of the outer web unit of the upper steel arch tower segment 8 and the lower steel arch tower segment 7 changes in a quadratic parabola along the central axis of the steel arch tower.

[0065] (like Figure 2 As shown in the above embodiment, further: the upper vertical hinge 6 and the lower vertical hinge 5 are respectively composed of a load-bearing plate unit 4 and a partition 2.
