The invention belongs to the technical field of bridge construction, and particularly relates to a sling structure of a three-tower four-span cable crane and a using method. A sling structure of a three-tower four-span cable crane comprises a first tower, a second tower, a third tower, a first sports car and a second sports car, a first sports car upper hanging frame and a first sports car lower hanging frame are connected to the lower portion of the first sports car, and a second sports car upper hanging frame and a second sports car lower hanging frame are connected to the lower portion of the second sports car. A first hoisting winch and a first friction type traction winch are arranged on the side, away from the second tower, of the first tower, and a second hoisting winch and a second friction type traction winch are arranged on the side, away from the second tower, of the third tower. Anchoring points and cable rotating points of the first traction cable steel wire rope, the second traction cable steel wire rope, the first hoisting cable steel wire rope and the second hoisting cable steel wire rope are all arranged on the top of the second tower, the problems that the space of the top of the second tower is limited, and a winch cannot be arranged are solved, the sling structure is simplified, and the use cost is reduced.
本发明属于桥梁施工技术领域,特别涉及一种三塔四跨缆索吊机的吊索结构及使用方法。一种三塔四跨缆索吊机的吊索结构,包括一号塔、二号塔、三号塔、一号跑车和二号跑车,一号跑车下方连接有一号跑车上挂架和一号跑车下挂架,二号跑车下方连接有二号跑车上挂架和二号跑车下挂架,一号塔远离二号塔一侧分别设有一号起重卷扬机、一号摩擦型牵引卷扬机,三号塔远离二号塔一侧分别设有二号起重卷扬机、二号摩擦型牵引卷扬机。本发明通过将一号牵引索钢丝绳、二号牵引索钢丝绳、一号起重索钢丝绳和二号起重索钢丝绳的锚固点及转索点均布置在二号塔塔顶,解决了二号塔塔顶空间受限,无法布置卷扬机的难题,简化了吊索结构,降低使用成本。
