[0060] In the embodiment, the horizontal positioning spherical hinge 2 is arranged away from the line 7, one end of the arc-shaped slide 3 is connected with the bridge, and the other end extends away from the line 7, and the rotating body mechanism can drive the rotating body section to rotate along the arc-shaped slide 3 with the horizontal positioning spherical hinge 2 as the center.

[0061] In the embodiment, the horizontal positioning spherical hinge 2 is arranged away from the line 7, one end of the arc-shaped slide 3 is connected with the bridge, and the other end extends away from the line 7, and the rotating body mechanism can drive the rotating body section to rotate along the arc-shaped slide 3 with the horizontal positioning spherical hinge 2 as the center.

[0062] S1: The bridge is divided into a line front section 11, a first section 12, a second section 13 and an n section along the length direction (from left to right in the drawing) by a plurality of in-situ piers 16, the line front section 11 refers to all the bridges before the line 7 (left side of the first section 12), and the first section 12 corresponds to the line 7; in the embodiment, the first section 12 and the second section 13 of the bridge are the rotating body sections, the remaining bridges are non-rotating body sections, and the preset position of the horizontal positioning spherical hinge 2 is on the in-situ pier 16 on the right side of the second section 13;

The rotating segment is cut and separated from the non-rotating segment and the support through the cutting mechanism 1. Specifically, the original in-situ support pier 16 on the right side of the second segment 13 is first separated from the support through the cutting mechanism 1, the horizontal positioning spherical hinge 2 is installed, the position corresponding to the horizontal positioning spherical hinge 2 on the rotating segment is weighted, the weight on the first segment 12 is removed, and the remaining original in-situ support piers 16 corresponding to the first segment 12 and the second segment 13 are cut and separated from the support through the cutting mechanism 1.

At this time, the rotating segment has moved away from the line 7, and the disassembly work can be carried out without affecting the line 7.

[0068] Embodiment 2

[0069] The difference between this embodiment and embodiment 1 is that the first segment 12, the second segment 13 and the third segment 14 of the cross-line bridge are the rotating segment. The temporary cable tower 5 has two, corresponding to the support pier on the right side of the first segment 12 and the original in-situ support pier 16 on the right side of the second segment 13.

[0070] In step S4, the temporary cable tower 5 performs secondary tensioning on the rotating segment through the cable 6, lifts the rotating segment upward, and then does not need to weight the position corresponding to the horizontal positioning spherical hinge 2 on the rotating segment. The first segment 12, the second segment 13 and the third segment can be directly cut and separated from the support through the cutting mechanism 1, and then the horizontal positioning spherical hinge 2 can be installed.

[0071] In addition, compared with embodiment 1, the position of the horizontal positioning spherical hinge 2 in this embodiment is unchanged, that is, the center of rotation is unchanged, but the configuration on both sides of the center of rotation is more balanced than that of embodiment 1, and the stability is better in the actual working process. The length of the rotating segment is also longer than that of embodiment 1, so the rotating segment can be moved to a position farther away from the line 7.

[0072] Embodiment 3

[0073] The difference between this embodiment and embodiment 1 is that the horizontal positioning spherical hinge 2 is arranged close to the edge of the line 7, and the two ends of the arc-shaped sliding track 3 are arranged close to the outer edge of the line 7, and the swivel mechanism can drive the swivel segment to rotate along the arc-shaped sliding track 3 with the horizontal positioning spherical hinge 2 as the center.

[0074] Further comprising: a translation sliding track 8, one end of the translation sliding track 8 is connected with the line 7, and the other end extends away from the line 7; and a horizontal dragging sliding block 9 arranged on the translation sliding track 8, the swivel mechanism can drive the swivel segment to rotate to the horizontal dragging sliding block 9 along the arc-shaped sliding track 3, and then horizontally slide along the translation sliding track 8 away from the line 7.

[0075] In step S1, the first segment 12 is taken as the swivel segment, and the remaining overline bridge is taken as the non-swivel segment, and the horizontal positioning spherical hinge 2 needs to be arranged on the temporary support 15 close to the edge of the line 7. Since the horizontal positioning spherical hinge 2 is arranged on the temporary support 15, the installation can be completed in step S1. In step S2, the arc-shaped sliding track 3 is arranged to be 180°, and the two ends are arranged close to the outer edge of the line 7; in step S5, the swivel mechanism can drive the swivel segment to rotate along the arc-shaped sliding track 3 with the horizontal positioning spherical hinge 2 as the center to a position adjacent to and parallel to the line 7; at this time, the swivel segment has been completed swivel, but the swivel segment is still adjacent to the line 7, and here the disassembly of the swivel segment may affect the line 7, the swivel segment is synchronously jacked up by a jacking device (such as a jack), the horizontal dragging sliding block 9 is installed between the translation sliding track 8 and the lower surface of the swivel segment, the horizontal dragging sliding block 9 can support the swivel segment, the horizontal positioning spherical hinge 2 and the support foot 4 are removed, and the swivel mechanism drags the swivel segment away from the line 7 along the translation sliding track 8 through the horizontal dragging sliding block 9. The horizontal dragging module can adopt an existing wheel type translation dragging structure and the like, as long as it can drag and translate the swivel segment in the horizontal direction.

[0076] Compared with embodiment 1 and embodiment 2, the overline bridge that needs to be swiveled in this embodiment is only the first segment 12, and the cutting, rotating and other processes of the swivel segment consume relatively less time, but this embodiment can only rotate the swivel segment to a position adjacent to the line 7, and still needs to cooperate with the horizontal dragging module and the translation sliding to secondarily transfer the swivel segment. After the secondary transfer, the swivel segment can be placed on the landing support 10, and then the disassembly and removal work is performed, without affecting the line 7.

[0077] According to different models of the overline bridge and the line 7, different swivel modes disclosed in embodiment 1 to embodiment 3 can be flexibly selected to achieve the horizontal swivel purpose of the swivel segment.

[0078] In the description of the utility model, need understanding is, the term "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and so on indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawing, just for the convenience of describing the utility model, and not indicate or imply that the indicated device or element must have a particular orientation, construct and operate in a particular orientation, therefore can not be understood as limiting the utility model.

[0079] The above-described embodiments are only descriptions of the preferred modes of the utility model, and do not limit the scope of the utility model, and various modifications and improvements to the technical solutions of the utility model made by those skilled in the art without departing from the design spirit of the utility model should fall within the protection scope defined by the claims of the utility model.
