Description

Technical Field

[0001] This utility model relates to the field of bridge engineering construction technology, and in particular to a multi-gate saddle for preventing cable slippage. Background Technology

[0002] In existing technologies, cable-stayed rigging systems are commonly used in the construction of long-span bridges. These systems lift prefabricated components into place, primarily for crossing canyons, rivers, or sections of water with deep and rapid currents. A cable-stayed rigging system can be divided into five basic components: the load-bearing cable (main cable), the lifting cable, the traction cable, the tower, and the anchoring device. Its working principle is that the load-bearing cable supports the load and serves as the track for the trolley. The lifting and traction devices on the main cable trolley lift, raise, transport, and install the components. During operation, one end of the lifting cable, traction cable, and load-bearing cable passes through a saddle located at the top of the tower and is erected above the ground. Simultaneously, the weight of multiple cables is transferred to the tower through the saddle, and the tower bears the weight of the cables.

[0003] In existing multi-gantry cable saddles, the wall panels used to separate the cables are generally lower than the pulleys in the saddle. During actual construction, when the load-bearing cable is pulled obliquely in the horizontal direction, an angle will be formed between the load-bearing cable and the pulley in the saddle, which will cause the load-bearing cable to slip out of the pulley and affect the stability of the cable saddle.

Its working principle is that the load-bearing cable supports the load and serves as the track for the trolley. The lifting and traction devices on the main cable trolley lift, raise, transport, and install the components.
