Description

Technical Field

[0001] This application relates to the field of bridge construction technology, specifically to a rotating tower system that can realize horizontal and vertical rotation of arch ribs. Background Technology

[0002] In the field of bridge technology, the arch rib is the core load-bearing component of the arched load-bearing structure. Its shape is arc-shaped, and it is connected to the foundation through the arch feet at both ends to form the load-bearing skeleton of the arched structure.

[0003] Currently, the conventional method for arch rib installation is to use separate horizontal and vertical rotation installation equipment and construction methods around the arch foot. Horizontal rotation installation involves assembling prefabricated arch rib segments on the ground or temporary supports, then using the arch foot as the rotation center, and employing a turntable or other horizontal rotation drive device to rotate the arch rib horizontally around a vertical axis until it reaches the designed installation position. Vertical rotation installation also uses the arch foot as the rotation center, utilizing a rotating tower as support, and a traction device to drive the arch rib vertically around a horizontal axis, lifting and rotating it from a horizontal or inclined state to the designed installation angle.

[0004] In the aforementioned installation method of separating horizontal and vertical rotation, two different sets of equipment are used to perform horizontal and vertical rotation respectively. Because the distance between the rotating tower and the front tension point of the arch rib is relatively far, a large counterweight must be installed at the rear end of the arch foot to achieve force balance during the arch rib rotation process. Since the counterweight is located at the bottom of the arch foot, it affects the permanent structure and must be considered during the construction drawing design stage; otherwise, design changes will be necessary, which will not only delay the construction period but also further increase the project cost and may even affect the structural safety of the project.

[0005] In summary, existing arch rib installation equipment with separate horizontal and vertical rotation has drawbacks such as adverse effects on permanent structures, high design and construction costs, and easy delays in construction period. Therefore, developing an arch rib installation equipment that can take into account both horizontal and vertical rotation functions, eliminates the need for a counterweight at the rear end of the arch foot, and can eliminate the impact on permanent structures has become an urgent technical problem to be solved in this field.

Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] This invention provides a rotating tower system capable of both horizontal and vertical rotation of the arch ribs, such as... Figure 1 , 2 As shown in 3, 12, 13, 14, and 15, including Rotating tower 10; The first rotating device 20 is located at the lower part of the rotating tower 10 and is used to drive the arch rib 100 to rotate horizontally about the central vertical axis of the rotating tower 10. The second rotating device 30 is disposed at the top of the rotating tower 10; The horizontal rotation lifting cable 40 includes at least one pair, with one end of any horizontal rotation lifting cable 40 being rotatably connected to the second rotating device 30 and the other end hanging down. The horizontal rotation lifting cable 40 is controlled to be extended and retracted after the second rotating device 30 rotates. The vertical rotating cable 50 has one end rotatably connected to the second rotating device 30 and the other end hanging down. The vertical rotating cable 50 is controlled to be extended and retracted after the second rotating device 30 rotates.

[0024] In practice, the center of the rotating tower 10 is located on the bridge axis, coinciding with the center of gravity of the arch rib 100 in its horizontal position before rotation. The height of the rotating tower 10 is not less than the maximum vertical lifting height of the arch rib 100 during its vertical rotation.

[0025] Arch rib 100 horizontal rotation: Arch rib 100 is horizontally aligned in the transverse direction (referring to the direction perpendicular to the bridge axis and parallel to the cross-section of the bridge; in an arch bridge, the transverse direction is the direction perpendicular to the vertical plane where the arch rib 100 arc lies; in water, it is the direction with the water flow). Figure 12 As shown; then, at least one pair of horizontal lifting cables 40, with their drooping ends evenly distributed from front to back, are fixedly connected to the arch rib 100, as follows. Figure 13 As shown; then the second rotating device 30 is activated, the horizontal rotating lifting cable 40 is wound up, and the connection length of the horizontal rotating lifting cable 40 is adjusted, causing the arch rib 100 to be lifted to a certain height; then the first rotating device 20 is activated, causing the arch rib 100 to rotate horizontally about the central vertical axis of the rotating tower 10, so that the arch rib 100, which is lifted by the horizontal rotating lifting cable 40, is driven to rotate horizontally until it reaches the preset position along the bridge direction, such as... Figure 14As shown; in order to improve stability during rotation, a temporary tie rod 60 is connected between the front end and the bottom end of the arch rib (also known as the connecting end of the arch rib 100).

[0026] Vertical rotation of arch rib 100: Before vertical rotation of arch rib 100, arch foot 70 must be installed and set up. Before vertical rotation, the first rotating device 20 and the horizontal rotation lifting cable 40 on the rotating tower 10 must be removed.

[0027] First, the bottom end of the arch rib is rotatably connected to the arch foot 70 via the vertical hinge 71. Then, one end of the vertical rotating cable 50 is fixedly connected to the front end (free end) of the arch rib 100. Next, the second rotating device 30 is activated to wind up the vertical rotating cable 50, causing the front end of the arch rib 100 to rise. The rear end of the arch rib rotates along the vertical hinge 71, raising the included angle, until the arch rib 100 rotates vertically to the designed position, such as... Figure 15 As shown.

[0028] In this invention, the rotating tower 10 is not segmented in the height direction. A first rotating device 20 is installed at the height position corresponding to the horizontal arch rib 100 of the rotating tower 10. When the arch rib 100 rotates horizontally, it rotates around its center of gravity without the need for counterweights. The first rotating device 20 is arranged radially, providing only the power for horizontal rotation and not bearing the weight of the arch rib 100. A second rotating device 30 is installed at the top of the rotating tower 10, connected to the arch rib 100 via a horizontal rotation lifting cable 40, bearing the entire weight of the arch rib 100. It rotates horizontally in conjunction with the first rotating device 20, and vertical rotation is achieved via a vertical rotation cable 50. In this invention, the horizontal and vertical rotations of the arch rib 100 share a single rotating tower 10. The center of the rotating tower 10 is collinear with the center of gravity of the horizontal arch rib 100. During use, wind bracing is not used or only partially installed. After rotation is completed, the rotating tower 10 can be removed without affecting the permanent structure.

[0029] This invention discloses a rotating tower 10 system capable of horizontal and vertical rotation of an arch rib. The system includes a rotating tower 10, a first rotating device 20 located at the lower part of the rotating tower 10, and a second rotating device 30 at the top. It also includes a horizontal rotation lifting cable 40 and a vertical rotation cable 50 connected to the second rotating device 30. The center of the rotating tower 10 is collinear with the center of gravity of the horizontally assembled arch rib 100. During horizontal rotation, the first rotating device 20, the second rotating device 30, and the horizontal rotation lifting cable 40 work together to achieve horizontal rotation of the arch rib 100. During vertical rotation, the second rotating device 30 winds up the vertical rotation cable 50. This invention uses a single rotating tower 10 to complete both horizontal and vertical rotation, eliminating the need for counterweights, reducing the use of wind braces, having no impact on the permanent structure, improving construction stability and efficiency, and reducing costs.

[0030] According to an embodiment of the present invention, a rotating tower 10 system capable of horizontal and vertical rotation of the arch ribs is provided, such as... Figure 3 , 8As shown in Figure 13, a balancing cable 80 is also included, one end of which is connected to the top of the rotating tower 10, and the other end is connected to a temporary anchor. The anchor bearing capacity of the temporary anchor of the balancing cable 80 is not less than the maximum unbalanced load during the rotation of the arch rib 100. After the arch rib is rotated into place, the balancing cable 80 is installed for use during vertical rotation. The balancing cable 80 can effectively balance the force on the rotating tower 10, significantly improve the stability of the rotating tower 10 during the vertical rotation of the arch rib 100, and ensure construction safety.

[0031] According to an embodiment of the present invention, a rotating tower 10 system capable of horizontal and vertical rotation of the arch ribs is provided, such as... Figure 4 , 5 As shown in Figures 6 and 7, the first rotating device 20 includes a lower rotating disk 24, an upper rotating disk 22, and a traction system. The lower rotating disk 24 is rigidly fixed to the arch rib 100, and the rotating tower 10 is rigidly connected to the upper rotating disk 22. Under the action of the traction system, the upper rotating disk 22 can drive the lower rotating disk 24 to rotate horizontally relative to the upper rotating disk about the central vertical axis of the rotating tower 10. Specifically, the lower rotating disk 24 is fixedly connected to the arch rib 100 through the arch rib connector 23, and the upper rotating disk 22 is fixedly connected to the rotating tower 10 through the rotating tower connector 21. The traction system includes a horizontal rotating jack and a traction reaction seat, with the horizontal rotating jack disposed on the upper rotating disk 22. During operation, the horizontal rotating jack uses the traction reaction seat as the force support point and applies a horizontal traction driving torque to the lower rotating disk 24, so that the lower rotating disk 24 rotates horizontally relative to the stationary upper rotating disk 22 with the central vertical axis of the rotating tower 10 as the axis, thereby driving the arch rib 100, which is rigidly fixed to the lower rotating disk 24, to rotate synchronously, completing the horizontal rotation operation of the arch rib 100 relative to the rotating tower 10.

[0032] In this embodiment, the lower rotating disk 24 is an arc-shaped ring that is arranged around the outer periphery of the rotating tower 10 and can rotate relative to the rotating tower 10, and the upper rotating disk 22 is an arc-shaped ring that is arranged around the outer periphery of the rotating tower 10 and fixedly connected to the rotating tower 10.

[0033] In one embodiment, the rotating tower 10 includes multiple pipe piles arranged circumferentially, with fixed horizontal couplings provided on the inner circumference of the multiple pipe piles.

[0034] Before vertical rotation, the fixed connection between the lower rotating plate 24 and the arch rib 100 must be removed.

[0035] According to an embodiment of the present invention, a rotating tower 10 system capable of horizontal and vertical rotation of the arch ribs is provided, such as... Figure 8 , 9As shown in Figures 10 and 11, the second rotating device 30 includes a lower turntable 31, an upper turntable 32, and a traction system. The lower turntable 31 is fixedly connected to the top of the rotating tower 10, and the upper turntable 32 can rotate horizontally relative to the lower turntable 31 around the central axis of the rotating tower 10 under the action of the traction system. The horizontal rotating lifting cable 40 and the vertical rotating cable 50 are connected to the side of the upper turntable 32 to wind up or unwind the horizontal rotating lifting cable 40 and the vertical rotating cable 50 when the upper turntable 32 rotates.

[0036] When in use, the traction system is activated to drive the upper turntable 32 to rotate around the central axis of the rotating tower 10, so that the upper turntable 32 rotates horizontally relative to the lower turntable 31. Since the horizontal rotating lifting cable 40 and the vertical rotating cable 50 are respectively connected to the side of the upper turntable 32, the upper turntable 32 can rewind or unwind the horizontal rotating lifting cable 40 and the vertical rotating cable 50 when rotating.

[0037] According to an embodiment of the present invention, a rotating tower 10 system capable of horizontal and vertical rotation of the arch ribs is provided, such as... Figure 8 , 9 As shown, both the horizontal rotating lifting cable 40 and the vertical rotating cable 50 are equipped with tension adjustment devices 90, which are used to adjust the tension of the cable body.

[0038] Of course, the present invention is not limited to the above-described embodiments.
