Description

Technical Field

[0002] The bridge steering saddle (also called steering saddle, steering device) is a structural component used in the steering system of the bridge. It usually appears in cable-stayed bridges or suspension bridges. Its main function is to guide and control the direction of the bridge cable to ensure that the cable force is transmitted on the correct path, thereby maintaining the stability and safety of the bridge.

[0003] The main cables or stays of a bridge are changed in direction by saddles. For example, in a suspension bridge or cable-stayed bridge, the saddle is used to guide the direction of the suspension cable from vertical or diagonal to a suitable inclination angle to ensure effective transmission of the cable force.

[0004] Since the bridge steering saddle is a durable device and difficult to maintain, the structure should be simplified as much as possible. Through reasonable structural analysis, over-design should be avoided, the geometry and structure of the saddle should be simplified, and unnecessary complexity should be reduced.

[0005] For example: Patent publication number: CN221721363U is a bridge steering saddle, which specifically discloses a saddle, wherein a clamping mechanism is arranged inside the saddle, and the clamping mechanism comprises: a first pressure plate and a second pressure plate, wherein the outer ends of the first pressure plate and the second pressure plate are both provided with guide rods, and the outer ends of the guide rods are provided with sliding guide blocks, and the outer sides of the sliding guide blocks are located inside the first pressure plate and the second pressure plate, and movable sleeves are provided inside the first pressure plate and the second pressure plate, and an anti-drop pad is provided at the end of the guide rod located away from the sliding guide block, and the interior of the sliding guide block is connected to a limiting ratchet through an elastic rotating shaft, and the outer side of the sliding guide block is provided with a clamping groove on the inner side wall of the saddle, and a limiting rack is provided inside the clamping groove, and mounting ear plates are provided on the upper surfaces of the first pressure plate and the second pressure plate, and fastening bolts are provided inside the mounting ear plates.

Therefore, the device needs to be regularly repaired, inspected, maintained, and replaced, and is also prone to major accidents.
