Suspension cable of space cable rope structure

Abstract

The invention discloses a sling for a spatial cable structure, which comprises a sling body, an upper-end anchorage connected with the upper end of the sling body, and a lower-end anchor device connected with the lower end of the sling body, wherein the lower-end anchor device comprises a lower-end anchorage, a connecting rod, a base and a revolute pair positioned between the connecting rod and the base, the connection rod is a long rod with a cylinder head on the lower end, the revolute pair is a ring-shaped ball support with an inner spherical surface as the end surface of one end, the base is a tower-shaped body with a step hole, a small upper end and a large bottom end, the end surface of the bottom end of the base is an inclined surface or a plane, the upper end of the connecting rod passes through the step hole of the base and is connected with the lower-end anchorage, the cylinder head on the lower end of the connecting rod is locked on the end surface of the inner spherical surface of the revolute pair in the step hole of the base, and the lower end of the sling body is in anchoring connection with the lower-end anchorage of the lower-end anchor device. The sling can rotate larger angles, move, extend, and be adjusted with the length, and can fully adapt the demand of a suspension bridge adopting spatial cables to the structural form of the sling.

Description

Technical field: [0001] The invention relates to a bridge suspension, in particular to a suspension bridge suitable for a space cable structure. Background technique: [0002] In recent years, with the continuous innovation of the structure form of the suspension bridge, people have designed a very novel and beautiful new type of suspension bridge. The projection on the vertical surface perpendicular to the bridge deck is also curved; therefore, during the construction process of this type of suspension bridge from the empty cable state to the bridge state, it is required that the suspension cable body can rotate at a large angle and move, expand and contract. Adjustment. A conventional suspension bridge sling is composed of an upper anchorage, a sling body and a lower anchorage device. The lower anchorage device generally includes a lower anchorage 16 and a deviation correction device. The sling body passes through the embedded pipe 19 in the box girder and is anchored On...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a suspension bridge sling that can adapt to the space cable structure. During the construction process of the sling from the empty cable state to the bridge state, the sling body can rotate at a larger angle and It can be moved, stretched, and adjusted in length to solve the problem that the structure of the existing sling cannot adapt to the construction of a suspension bridge with a space cable structure
