A high-strength anti-bending fatigue spoke cable

Abstract

The invention discloses a high-strength and bending-fatigue-resistant spoke cable, which comprises a steel bundle cable body, an upper anchor fork lug joint and a lower anchor cup, wherein steel wires at two ends of the steel bundle cable body are uniformly separated by virtue of a wire separating plate and are respectively fixedly arranged inside the upper anchor fork lug joint and the lower anchor cup; a bending limiter assembly is arranged on the upper anchor fork lug joint and a bending limiter assembly is arranged on the lower anchor cup; the bending limiter assemblies are sleeved on the steel bundle cable body; one end of the corresponding bending limiter assembly is arranged on the upper anchor fork lug joint and one end of the corresponding bending limiter assembly is arranged on the lower anchor cup, and seal compression rings are arranged between the other ends of the two bending limiter assemblies and the steel bundle cable body; and seal dampers are filled between the bending limiter assemblies and the steel bundle cable body as well as between the seal compression rings and the steel bundle cable body. The bending stress of the spoke cable disclosed by the invention is absorbed by virtue of the reliable constraint of the bending limiter assemblies and by virtue of the seal dampers, so that the stress uniformity of the high-strength steel wires under working state is effectively guaranteed; and the spoke cable is good in damping effect and is reliable to seal.

Description

technical field [0001] The invention relates to the field of drag cables, in particular to a high-strength bending fatigue-resistant spoke cable. Background technique [0002] The spoke cable is a special kind of cable in the space structure, which is mainly used in the structure of the Ferris wheel and the tour turntable to connect the middle hub and the wheel rim, and is the stressed member that carries its main load. With the continuous development of the economies of various countries, the number of cables used in Ferris wheel and tour turntable projects is gradually increasing, and the diameter of the disk is getting larger and larger, which puts forward higher requirements for the bending fatigue strength and waterproof performance of the cables. What adopted in the stay cable is to arrange the form of the shock absorber and the outer cover waterproof cover in the embedded pipe to play the effect of shock absorption and sealing waterproof. However, this method cannot ...

Problems solved by technology

However, this method cannot be used directly due to the limitation of the space structure of the Ferris wheel and the particularity of the rotation of the Ferris wheel.

Therefore, the development of modern large-diameter ferris wheels has put forward higher requirements for the use of spoke cables. However, due to the functional defects of the existing shock absorption and protection measures, the use of spoke cables for large-diameter ferris wheels cannot be satisfied. Require
