Embodiment Construction

[0022] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] to combine figure 1 As shown, the device for multi-suspension hoisting in this embodiment includes four connecting rods 1 , one oil cylinder 2 and one hydraulic power unit 3 . Among them, the four connecting rods 1 are sequentially connected end-to-end through pin shafts to form a four-link structure. The oil cylinder 2 is located inside the four-bar structure and the two ends of the oil cylinder 2 are respectively connected to the two opposite ends of the four-bar structure. Junction points connect. When the four-bar linkage structure is placed in the vertical direction and connected with the rigging, the highest connection point 1a and the lowest connection point 1b in the four-bar linkage structure are connected to the upper rigging 41 and the lower rigging 42 respectively, and the two in the middle area The conn...

Abstract

The invention belongs to the technical field of equipment lifting and discloses a device used for multi-lifting-point lifting. The problems that when existing methods are adopted for carrying out leveling operation of multi-lifting-point lifting, the labor intensity of operators is large, operation efficiency is low, and safety and reliability are low are solved. The device comprises four connecting rods, an oil cylinder and a hydraulic power unit. The four connecting rods are sequentially connected end to end to form a four-connecting-rod structure, and the oil cylinder is located in the four-connecting-rod structure. When the four-connecting-rod structure is placed in the vertical direction, the highest connecting point and the lowest connecting point in the four-connecting-rod structureare connected with an upper rope and a lower rope correspondingly, and the other two connecting points are connected with the two ends of the oil cylinder correspondingly. The hydraulic power unit isconnected with the oil cylinder and used for driving telescopic action of the oil cylinder. When the device is adopted for carrying out leveling operation of multi-lifting-point lifting, the labor intensity of the operators can be greatly reduced, operation efficiency can be improved, and safety and reliability in the operation process can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of equipment hoisting, and in particular relates to a device and system for hoisting at multiple hoisting points. Background technique [0002] The steel containment vessel (CV) of nuclear power plant is one of the most important safety protection equipment of the nuclear island, and the reactor, steam generator and other main process system equipment are installed inside it. The steel containment vessel is a capsule-shaped container as a whole, consisting of large modules such as the bottom head, the first ring of the cylinder, the second ring of the cylinder, the third ring of the cylinder, and the top head. Each module has the characteristics of large tonnage, large diameter, high height and thin wall thickness. In the existing mature installation process, when the overall hoisting of each module is carried out in the way of multi-lifting points, the connection between the modules and the hoisting equipm...
