[0042] The embodiment of the present invention provides a cable-stayed cable hanging device and method, which can solve the technical problem in the related art that the existing steel truss cable-stayed bridge is difficult to form a cable hanging operation platform on the bridge deck because the bridge deck does not form a force system with the beam body, resulting in difficulty in bridge deck cable hanging operation.

When the hook 31 is connected to the inclined cable 5, the rotating component 2 rotates to drive the moving component 3 and the inclined cable 5 to rotate, and the moving component 3 slides to drive the inclined cable 5 to move laterally.

[0044] The inclined cable hanging device provided by the embodiment of the present invention is provided with a base, a rotating component and a moving component. The base is arranged on the top of the beam erecting crane, the rotating component is arranged on the base and is rotatably connected with the base, the moving component is arranged on the top of the rotating component and can slide in the horizontal direction, and a liftable hook is provided on the moving component. When the hook is connected with the inclined cable, the rotating component rotates to drive the moving component and the inclined cable to rotate, and the sliding of the moving component drives the inclined cable to move laterally. By fixing the base on the top of the beam erecting crane, a cable hanging operation platform is formed on the bridge deck by using the beam erecting crane, and the position of the inclined cable is adjusted by the rotating component and the moving component to realize the installation of the beam end hanging cable, which reduces the difficulty of bridge deck hanging cable, improves the construction efficiency, and ensures that the installation of the beam end inclined cable is safe and efficient.

[0045] As an optional implementation, in an embodiment of the invention, see Figure 1 and Figure 2As shown, the rotating assembly 2 includes: a rotating support 21, a rotating beam 22 and a driving assembly 23. The rotating support 21 is arranged above the base 1 and is rotatably connected thereto. A first gear 211 is provided on one side of the rotating support 21. The rotating beam 22 is arranged above the rotating support 21. The driving assembly 23 is arranged on the first gear 211, and is used to drive the first gear 211 to rotate, and drive the rotating support 21 and the rotating beam 22 to rotate along the circumferential direction of the base 1. When the hook 31 is connected to the inclined cable 5, the first gear 211 is driven to rotate by the driving assembly 23, and the first gear 211 drives the rotating support 21 and the rotating beam 22 to rotate along the circumferential direction of the base 1. The lateral position of the inclined cable 5 can be adjusted arbitrarily, and the operation is simple.

[0046] As an optional implementation, in an embodiment of the invention, see Figure 2 As shown, the driving assembly 23 includes: a second gear 231 and a reducer 232. The second gear 231 is arranged on one side of the rotating support 21 and meshes with the first gear 211. The reducer 232 is arranged above the second gear 231 and is used to drive the second gear 231 and the first gear 211 to rotate. The reducer 232 rotates to drive the second gear 231 to rotate. Since the second gear 231 meshes with the first gear 211, the rotation of the second gear 231 further drives the first gear 211 to rotate, thereby driving the rotating support 21 and the rotating beam 22 to rotate along the circumferential direction of the base 1. The rotation speed of the rotating support 21 and the rotating beam 22 can also be adjusted by the reducer 232, so that the installation of the beam end inclined cable is safe and efficient.

[0047] As an optional implementation, in an embodiment of the invention, see Figure 2 and Figure 3 As shown, the rotating beam 22 includes: a column 221 and a cross beam 222, the column 221 is arranged above the rotating support 21, and the cross beam 222 is arranged above the column 221 in the horizontal direction. The rotation of the rotating support 21 drives the column 221 and the cross beam 222 to rotate, and the cross beam 222 extends forward in the horizontal direction. The column 221 forms a support between the rotating support 21 and the cross beam 222. The column 221 and the cross beam 222 can rotate 360 ​​degrees under the drive of the rotating support 21, so as to adjust the position in real time and connect with the inclined cable 5. After being connected with the inclined cable 5, the lateral position of the inclined cable 5 can be adjusted arbitrarily to be installed in the cable guide tube.

[0049] As an optional implementation, in an embodiment of the invention, see Figure 1 and Figure 2 As shown, the moving assembly 3 includes: two pulleys 32 and an electric hoist 33. The two pulleys 32 are arranged on the slide rail 2222 below the crossbeam 222 at intervals and can slide along the length direction of the slide rail 2222.

The hook 31 can be connected to the inclined cable 5 when it descends, and the height and inclination angle of the inclined cable 5 can be adjusted when the hook 31 rises. After being lowered and connected with the inclined cable 5, the two pulleys 32 can drive the electric hoist 33 to slide horizontally on the slide rail 2222, i.e., the crossbeam 222, and the electric hoist 33 further drives the hook 31 and the inclined cable 5 to slide horizontally, thereby adjusting the longitudinal position of the inclined cable 5, so that the inclined cable 5 is accurately located at the preset anchoring position and installed and fixed in the cable guide tube. The sliding speed of the pulley 32 and the lifting speed of the hook 31 can also be adjusted by the electric hoist 33, so that the installation of the inclined cable at the beam end is safe and efficient.

[0050] As an optional implementation, in an embodiment of the invention, see Figure 2 As shown, limit blocks 22221 are provided at both ends of the slide rail 2222, and the limit blocks 22221 are used to limit the movement range of the two pulleys 32, so that the two pulleys 32 can slide horizontally efficiently and accurately within the specified range, and prevent the two pulleys 32 from exceeding the predetermined sliding range of the slide rail 2222, thereby avoiding damage to or malfunction of the equipment, improving the working efficiency of the equipment, and preventing collision with other parts of the equipment, reducing wear and damage caused by collision, and extending the service life of the equipment.

[0051] As an optional implementation, in an embodiment of the invention, see Figure 2As shown, a limit plate 321 is provided on the side of the two pulleys 32 to prevent the pulleys 32 from being separated from the slide rail 2222. The limit plate 321 forms a barrier on the sides of the two pulleys 32 to prevent the two pulleys 32 from being separated from the slide rail 2222 when the crossbeam 222 rotates, thereby improving the stability of the pulley 32 and ensuring that the two pulleys 32 can remain stable and safe when running on the slide rail 2222.

[0052] As an optional implementation, in an embodiment of the invention, see Figure 2 As shown, the base 1, the rotating component 2, and the moving component 3 are all made of steel. The steel has high strength, good plasticity and heat resistance, uniform material, high working reliability, simple production, and good assembly performance. In addition, the base 1 and the top of the beam crane 4, and the rotating component 2 and the base 1 are connected by bolts, which are convenient for quick disassembly or installation and can be reused many times, thereby improving the utilization rate and practicality of the embodiments of the present invention.

Since the second gear 231 meshes with the first gear 211, the rotation of the second gear 231 further drives the first gear 211 to rotate, thereby driving the rotating support 21 and the rotating beam 22 to rotate along the circumferential direction of the base 1. The rotation speed of the rotating support 21 and the rotating beam 22 can also be adjusted by the reducer 232, so that the installation of the beam end inclined cable is safe and efficient.
