The invention relates to the technical field of bridge engineering, in particular to hoisting equipment for a double-layer bearing cable and a cable crane. The hoisting equipment comprises at least two groups of sports car assemblies which are movably arranged on an upper-layer load-bearing cable and a lower-layer load-bearing cable respectively; the lower hanging bracket is connected with the two groups of sports car assemblies, and the lower hanging bracket is used for being connected with a hoisted object; the two ends of the movable connecting rod assembly are movably hinged to the two sports car assemblies correspondingly. The separated and independent sports car assemblies are arranged on the upper bearing cable and the lower bearing cable, the two sports car assemblies are movably hinged through the movable connecting rods, when the double-layer bearing cable has the deformation difference, movement of the sports car assemblies fluctuates, the movable connecting rods are driven to change the position posture firstly, then fluctuation is transmitted to the other sports car assembly, and therefore the two sports car assemblies can be separated from each other. Therefore, the sensitivity degree of the two sports car assemblies to the deformation difference of the bearing cable is reduced. And furthermore, the over-high precision requirement of the tightening on the load-bearing cable adjustment is reduced.
本发明涉及桥梁工程技术领域,具体涉及一种双层承重索的起吊设备及缆索起重机。起吊设备包括:至少两组跑车组件,两组所述跑车组件分别用于活动设置在上层承重索和下层承重索上;下吊架,其与两组所述跑车组件相连,所述下吊架用于与起吊物相连;活动连杆组件,其两端分别与两组所述跑车组件活动铰接。本申请通过在上、下承重索布置的分离独立的跑车组件,并使用活动连杆对两个跑车组件进行活动铰接,当双层承重索出现变形差时,跑车组件的移动发生波动会首先带动活动连杆变化位置姿态,再将波动传递给另一个跑车组件,从而降低了两个跑车组件对于承重索的变形差的敏感程度。进而,降低勒对承重索调索的过高精度要求。
