Swing construction refers to a construction method where the bridge structure is fabricated (cast or assembled) at a location not aligned with the design axis, and then rotated into its final position. This method can transform work performed above obstacles into work performed on land or near the ground.

[0003] During bridge rotation, the upper crossbeams and other components need to rotate synchronously. During rotation, the upper crossbeams exert significant pressure on the lower supporting components, resulting in substantial frictional resistance and making it difficult to adjust the rotation angle. Therefore, this application proposes a bridge rotation structure. Utility Model Content

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figures 1-5 As shown in the figure, the bridge rotation structure provided by this utility model embodiment includes a lower turntable 1, an upper turntable 2, and a rotation traction system 3. The rotation traction system 3 is installed on the lower turntable 1. The upper turntable 2 is connected to the rotation traction system 3 for driving the upper turntable 2 to rotate around the lower turntable 1. A support leg mechanism 4 for guiding the upper turntable 2 is provided between the lower turntable 1 and the upper turntable 2.

[0028] For reference Figures 1-3 Multiple support mechanisms 4 are provided, and the multiple support mechanisms 4 are arranged in a circular array around the center line of the upper turntable 2. Each support mechanism 4 includes two support rollers arranged side by side, and the line connecting the centers of the two support rollers is aligned with the center of the upper turntable 2.

[0029] In order to connect the support mechanism 4 to the lower turntable 1, a support plate 5 that is rotatably connected to the support roller is provided on the lower turntable 1. A mounting bracket 6 for fixing the position between the support plate 5 and the lower turntable 1 is provided outside the support plate 5. Specifically, there are two support plates 5, which are aligned vertically. One of the support plates 5 rests against the upper surface of the lower turntable 1. The mounting bracket 6 is L-shaped and is detachably connected to the lower turntable 1 by bolts.

[0030] To guide the rotation of the upper turntable 2 via the support mechanism 4, several outer rotating guide plates 10 and inner rotating guide plates 11 are arranged in a circumferential array around the center line of the upper turntable 2 on the side of the upper turntable 2 near the lower turntable 1. One of the two support rollers in the support mechanism 4 rests against the outer wall of the outer rotating guide plate 10, and the other support roller rests against the outer wall of the inner rotating guide plate 11. The upper end face of the support roller rests against the lower end face of the upper turntable 2. Alternatively, there may be a gap between the support roller and the upper turntable 2 (in which case it cannot support the upper turntable 2). The outer rotating guide plate 10 and inner rotating guide plate 11 are provided with chamfered structures at the corners of the upper turntable 2 in the direction of travel to facilitate the entry of the support roller. The side of the outer rotating guide plate 10 and inner rotating guide plate 11 that mates with the support roller is provided with an arc-shaped surface whose center coincides with the center of the upper turntable 2.

[0031] Multiple support mechanisms 4 are set between the lower turntable 1 and the upper turntable 2. One end of the support mechanism 4 rests on the lower turntable 1 and the other end rests on the upper turntable 2. The support mechanism 4 is used to support and guide the upper turntable 2. An outer rotating guide plate 10 and an inner rotating guide plate 11 are set on the upper turntable 2. When the rotating traction system 3 drives the upper turntable 2 to rotate, the outer rotating guide plate 10 and the inner rotating guide plate 11 on the upper turntable 2 rotate synchronously with the upper turntable 2. During the rotation of the outer rotating guide plate 10 and the inner rotating guide plate 11, they cooperate with the support rollers in the support mechanism 4. The support rollers provide guidance for the rotation of the outer rotating guide plate 10 and the inner rotating guide plate 11, so that the upper turntable 2 can rotate smoothly and without tilting, thereby improving the stability of the upper turntable 2 during rotation and improving the stability of the bridge during rotation.

[0032] To facilitate the installation of the support rollers inside the support mechanism 4, a mounting positioning plate 7 is provided at the upper turntable 2. A wear-resistant plate 8 that fits against the outer wall of the support roller is provided at the mounting positioning plate 7. There are two wear-resistant plates 8, which respectively cooperate with the two support rollers. An intermediate plate 9 is provided between the mounting positioning plate 7 and the mounting frame 6. The mounting positioning plate 7 and the intermediate plate 9 are connected by bolts. The wear-resistant plates 8 and the mounting positioning plate 7 are connected by bolts or pins. The mounting positioning plate 7 is located on one side of the support roller, and its direction is aligned with the direction of travel of the upper turntable 2.

[0033] It should be noted that an outer auxiliary mounting plate 12 and an inner auxiliary mounting plate 13 are provided on the side of the lower turntable 1 near the upper turntable 2. The outer auxiliary mounting plate 12 is vertically aligned with the outer rotating guide plate 10, and the inner auxiliary mounting plate 13 is vertically aligned with the inner rotating guide plate 11. The outer auxiliary mounting plate 12 and the inner auxiliary mounting plate 13 are located on both sides of the support mechanism 4. During the installation of the support mechanism 4, the outer auxiliary mounting plate 12 is vertically aligned with the outer rotating guide plate 10, and the inner auxiliary mounting plate 13 is vertically aligned with the inner rotating guide plate 11. The position is calibrated by the outer auxiliary mounting plate 12 and the inner auxiliary mounting plate 13. In addition, a mounting positioning plate 7 and a wear-resistant plate 8 are provided on one side of the support mechanism 4 to provide positioning function for the installation of the support mechanism 4.

[0034] In summary, this utility model embodiment provides a bridge rotation structure. Multiple support mechanisms 4 are arranged between the lower turntable 1 and the upper turntable 2. One end of each support mechanism 4 rests against the lower turntable 1, and the other end rests against the upper turntable 2, providing support for the upper turntable 2. An outer rotating guide plate 10 and an inner rotating guide plate 11 are arranged on the upper turntable 2. When the rotation traction system 3 drives the upper turntable 2 to rotate, the outer rotating guide plate 10 and the inner rotating guide plate 11 on the upper turntable 2 rotate synchronously with the upper turntable 2. During the rotation of the outer rotating guide plate 10 and the inner rotating guide plate 11, they cooperate with the support rollers in the support mechanism 4. The support rollers provide guidance for the rotation of the outer rotating guide plate 10 and the inner rotating guide plate 11, allowing the upper turntable 2 to rotate smoothly and without tilting, improving the stability of the upper turntable 2 during rotation and thus improving the stability of the bridge rotation process.
