Description

Technical Field

[0002] Cable-stayed bridges occupy a vital position in modern bridge construction, and the construction quality of their cable-stayed towers is directly related to the structural stability and safety of the entire cable-stayed bridge. Hoisting the cable-stayed towers is a complex process that requires precise operation and reliable equipment. Due to the structural characteristics and load requirements of cable-stayed towers, traditional hoisting methods often face numerous challenges. For example, the irregular shape of cable-stayed towers and the enormous tensile forces they must withstand require hoisting equipment that can precisely adapt to their structure and evenly distribute the forces. Furthermore, during the hoisting process, it is necessary to ensure that the various components of the towers are securely connected to avoid slippage and deformation, placing high demands on both hoisting equipment and construction techniques.

[0003] In existing technologies, during the tower-end hoisting process of the cable-stayed cable, dynamic loads such as vibration from construction machinery and high-altitude wind disturbances can cause intermittent loosening at the connection points between the wire rope, the cable clamp, and the shoulder beam. Conventional cable clamps often use a single bolt for fastening, lacking a secondary locking mechanism. When the vibration frequency approaches the natural frequency of the connection, the bolt preload gradually decays, leading to relative slippage between the wire rope and the cable clamp. In extreme cases, this can cause increased localized wear of the wire rope, posing a risk of breakage. Furthermore, there are problems with achieving a stable connection.

DETAILED DESCRIPTION

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] The present embodiment provides a hanger for hoisting the tower end of a cable-stayed cable, which includes a horizontally arranged shoulder beam 15, a plurality of cable clamp assemblies, and a plurality of connecting assemblies. The shoulder beam 15 has lifting points at both ends for connecting to the hoisting equipment. The cable clamp assembly includes at least one set of dockable semicircular lifting rings 1 and steel plates 18. The steel plates 18 are fastened to the cable-stayed cable tower end 17 by bolts. The semicircular lifting rings 1 and the steel plates 18 are horizontally hinged, and the axis of the hinge shaft is parallel to the cable-stayed cable tower end 17. The axis allows the semicircular lifting ring 1 to rotate around the hinge axis in a vertical plane to adapt to changes in the lifting angle; and the interior of the semicircular lifting ring 1 is slidably connected to the first bracket 6 and the second bracket 7 along its arc profile, and rubber strips 9 are fixed on the surfaces of the two brackets for clamping the wire rope 2. A limit rod 14 is provided on the surface of the crossbeam 8 slidably connected inside the second bracket 7, and the limit rod 14 is clamped in the first bracket 6 to achieve limitation; the connecting assembly includes a wire rope 2 and a shackle 3, and the two ends of the wire rope 2 are respectively connected to the semicircular lifting ring 1 and the shoulder beam 15 of the cable clamp assembly corresponding to the lifting positions, and pass through the two rubber strips 9. After connection, a lasso connection is formed through the shackle 3, and the clamping cooperation of the limit rod 14 and the first bracket 6 can limit the wire rope 2 from slipping.

[0021] See also Figure 1 and Figure 2 In this embodiment, the cable clamp assembly's steel plate 18 is bolted to the cable tower end 17, with a gasket 19 positioned between them. Furthermore, a semicircular eye 1 is hingedly connected to the steel plate 18, with the surface of the semicircular eye 1 threaded with the steel wire rope 2. The interior of the semicircular eye 1 is slidably connected to the first bracket 6 and the second bracket 7. The interior of the second bracket 7 is slidably connected to the crossbeam 8. A limit rod 14 is fixedly connected to the surface of the crossbeam 8, which is clipped into the interior of the first bracket 6. Specifically, the steel plate 18 is adapted to the shape of the cable tower end 17, assembled and wrapped around the cable tower end 17, and vertically fixed to the surface of the cable tower end 17 by bolts (the axis of the bolt is perpendicular to the tower end surface), ensuring the stability of the fit between the steel plate 18 and the tower end; it should be noted that the shape of the steel plate 18 is set according to the specific structure of the cable tower end 17 of different shapes. At the same time, a gasket 19 is also installed between the steel plate 18 and the cable tower end 17, mainly because the gasket 19 can fill the tiny gap between the cable tower end 17 and the steel plate 18 due to the uneven surface of the tower end, making the cable clamp assembly more firmly fixed; evenly dispersing the bolt tightening pressure to avoid damage caused by excessive local force on the tower end; and can also act as a buffer layer during hoisting vibration to reduce the wear caused by relative friction between the two, thereby ensuring hoisting safety and extending the service life of the tower end and the steel plate 18.

[0022] The traditional lifting of the cable tower end 17 is optimized, and a semicircular lifting ring 1 is provided on the shoulder beam 15 and the cable tower end 17. The semicircular lifting ring 1 at both ends is connected by a steel wire rope 2. The semicircular lifting ring 1 is provided with a sliding bracket to limit and fix the joint of the semicircular lifting ring 1 and the steel wire rope 2, so that there is no shaking or rotation between the semicircular lifting ring 1 and the steel wire rope 2, thereby improving the stability and safety of the hanger and the cable tower end 17.

[0023] See also Figure 3 、 Figure 4 On the basis of the above, in order to clamp and stabilize the steel wire rope 2, a hanging groove 4 is provided on the surface of the semicircular lifting ring 1, and the hanging groove 4 is a convex groove. The inside of the hanging groove 4 is slidably connected to two round rods 5 along the arc contour of the semicircular lifting ring 1, one of the round rods 5 is fixedly connected to the surface of a first bracket 6, and the other round rod 5 is fixedly connected to the surface of a second bracket 7 (the two brackets slide along the hanging groove 4 with the round rod 5 to achieve displacement along the arc direction of the lifting ring), the surfaces of the first bracket 6 and the second bracket 7 are fixedly connected to rubber strips 9, and the two rubber strips 9 are clamped between the steel wire rope 2; and the first bracket 6 is a hollow square tubular structure, and a limiting groove 13 is provided on the surface of the first bracket 6, which is two spliced ​​arc-shaped grooves, the limiting groove 13 is connected to the inside of the first bracket 6, and the upper end width of the limiting groove 13 is greater than the lower end width. Specifically, the width of the upper end of the limiting groove 13 is greater than the width of the lower end, so that the limiting rod 14 can be inserted from the upper end of the limiting groove 13 and slide to the lower end of the limiting groove 13, so that the top circular plate of the limiting rod 14 is clamped in the limiting groove 13, thereby realizing a fixed connection between the first bracket 6 and the second bracket 7.

[0024] See also Figure 5 、 Figure 6 On the basis of the previous paragraph, in order to achieve a fixed connection between the first bracket 6 and the second bracket 7, a crossbeam groove 10 is provided on the surface of the second bracket 7, and the crossbeam groove 10 is connected to the interior of the second bracket 7. A slide rod groove 11 is provided inside the second bracket 7, and the interior of the slide rod groove 11 is horizontally slidably connected to the slide rod 12 along the length direction of the second bracket 7. The crossbeam 8 is fixedly connected to the surface of the slide rod 12, and the crossbeam 8 is a square plate structure. The height of the crossbeam 8 is less than the height of the crossbeam groove 10, and the limit rod 14 is a T-shaped circular plate structure in cross section. The limit rod 14 is clamped in the limit groove 13, and the outer circular plate diameter of the limit rod 14 is smaller than the upper end width of the limit groove 13, and the outer circular plate diameter of the limit rod 14 is larger than the lower end width of the limit groove 13. Specifically, the height of the beam 8 is smaller than the height of the beam groove 10 so that when the beam 8 slides out of the beam groove 10 of the second bracket 7, it can be rotated clockwise, and then the beam 8 is slightly lifted upward so that the limit rod 14 can be smoothly snapped into the limit groove 13.

[0025] In actual connection, the wire rope 2 is passed along the tangential direction of the semicircular eye 1 so that it passes through the clamping area of ​​the rubber strip 9 between the first and second brackets in the eye. After the wire rope 2 passes through the semicircular eye 1, a lasso connection is formed through the shackle 3. Then the crossbeam 8 inside the second bracket 7 is pulled downward and rotated clockwise. The limiting rod 14 fixed on the surface of the second bracket 7 is inserted from above the limiting groove 13. The limiting rod 14 slides to the bottom of the limiting groove 13 and is clamped. At this time, the rubber strip 9 on the surface of the first bracket 6 and the second bracket 7 clamps and fixes the wire rope 2, making the connection between the eye and the wire rope 2 more stable. After use, the crossbeam 8 is slightly lifted, the limiting rod 14 is taken out, and then the crossbeam 8 is stored in the second bracket 7.

[0026] In this embodiment, the shoulder pole beam 15 is provided with a plurality of adjustment holes 16 distributed along its length direction, and its semicircular lifting ring 1 is hinged to the adjustment hole 16; its wire rope 2 is connected to the shoulder pole beam 15 through the semicircular lifting ring 1 to adjust the connection position.

[0027] The specific implementation of the tower end hanger for hoisting the inclined cable of the present invention is as follows: Construction preparation: According to the parameters of the cable tower end 17, select the appropriate shoulder beam 15, cable clamp assembly and connection assembly, and check the quality of each component.

[0028] Cable clamp pre-installation: fit the steel plate 18 with the gasket 19 to the positioning mark of the cable tower end 17, and fix the steel plate 18 with bolts in a diagonal manner to ensure that the steel plate 18 fits tightly against the tower end surface; then hinge and assemble the semicircular lifting ring 1 and the steel plate 18 to form a cable clamp assembly.

[0029] Connection and assembly: Use the shackle 3 to connect one end of the wire rope 2 to the semicircular eye 1 of the cable clamp assembly, and pass it through the clamping area of ​​the rubber strip 9 between the first and second brackets in the semicircular eye 1; the other end is connected to the semicircular eye 1 at the adjustment hole 16 of the shoulder beam 15 through the shackle 3, and the sliding crossbeam 8 makes the limit rod 14 fit into the limit groove 13 of the first bracket 6 to complete the limitation of the wire rope 2; adjust the connection position of the shoulder beam 15 according to the distribution of the inclined cable to ensure that the wire rope 2 is evenly stressed.

[0030] Overall hoisting: Connect the hook of the hoisting equipment to the lifting points at both ends of the shoulder beam 15, hoist at a low speed to 10-20 cm from the ground, check the balance of the hanger and the connection of the components; after confirmation, hoist to the installation height of the cable tower end 17.

[0031] Hanger dismantling and maintenance: After the construction of the inclined cable is completed, the hanger should be dismantled in the reverse order of installation. First, release the limit rod 14 and then remove the wire rope 2; clean the dirt and rust on each component, repair or replace the worn rubber strip 9, limit rod 14 and other components, and store them in a classified manner for subsequent use.

[0032] The specific embodiment of the present invention transforms the structural advantages of the hanger (such as clamping with the rubber strip 9, engaging with the limit rod 14, and adapting with the adjustment hole 16) into safety and efficiency in actual construction through a standardized operating process (from preparation to maintenance): it avoids the risks of loosening and slipping in traditional hoisting through detailed control (such as diagonal tightening and low-altitude inspection), and adapts to the characteristics of different cable-stayed tower ends 17 through flexible adjustment (such as position adjustment and angle adaptation), ultimately achieving safe, accurate, and efficient hoisting of the cable-stayed tower ends 17, providing a replicable standardized operating solution for bridge construction.
