Turning device and turning method for heavy equipment in nuclear power plant

Abstract

The invention discloses a turnover device and a turnover method for heavy equipment of a nuclear power plant. The turnover device comprises a bracket, a turnover support and independent mechanisms. The bracket comprises a bracket body, and heavy equipment fixing straps and holders are arranged on the bracket body; an L-shaped turnover rod is arranged at one end of the bracket body, and a turnover hinge pin is arranged at a bent position of the turnover rod; the turnover support is matched with the turnover hinge pin on the turnover rod of the bracket, so that the heavy equipment can be turned over. The independent mechanisms include a fastening device and an embedded device, and the embedded device is preset in the ground of a workshop; the turnover rod, the fastening device and the turnover support are mechanically matched with one another, so that the bracket can independently keep in a vertical state without being suspended after the heavy equipment is turned over in place and the bracket is separated from hooks. The turnover device and the turnover method have the advantages that the turnover device is simple in structure and small in occupied space; by the aid of the turnover method, operation is simple, the construction period can be shortened, and the labor intensity can be relieved for workers.

Description

technical field [0001] The invention belongs to the field of hoisting and transportation, and in particular relates to an overturning device and an overturning method for heavy equipment in nuclear power plants. Background technique [0002] In the construction and maintenance of nuclear power plants, the turning and erecting of heavy equipment such as steam generators in the limited space inside the reactor building is an important link, and special turning tool devices are required for turning and erecting. Turning tools that are more commonly used today include collars with trunnions, turning brackets that support the trunnions, collar removal carts, and the like. Taking steam generator equipment during nuclear power plant construction as an example, its main working steps are: [0003] - The steam generator is transported to the platform height of the reactor building hall; [0004] -Fix the collar on the steam generator device; [0005] - Install the flip bracket and...
