Overturning erecting device and method

Abstract

The invention provides an overturning erecting device and method. The device comprises an equipment supporting frame (100) and multi-stage supporting arc section parts (200). When the equipment supporting frame (100) is overturned from the horizontal position to the vertical position, the multi-stage supporting arc section parts (200) are sequentially rolled on the ground along with overturning ofthe equipment supporting frame (100) to be used as supporting points. The structure is reasonable, and the equipment supporting frame (100) can be overturned synchronously when equipment is overturned under the effect of a crane. Particularly, the equipment supporting frame such as evaporation equipment and the ground do not need to be fixedly connected, and precise adjustment of the direction and precision is not needed.

Description

technical field [0001] The invention relates to a device for turning and erecting large-scale equipment, in particular to a device and method for turning and erecting equipment suitable for nuclear power plant evaporators and the like. In particular, it relates to a turning and erecting device for an evaporator of the main system equipment of a nuclear power plant. Background technique [0002] At present, large-scale equipment with a certain height in nuclear power plants is generally transported from the manufacturing plant to the power plant site by horizontal transportation. After arriving at the construction site, it needs to be turned to a vertical state before installation, and then hoisted in place. For example, the shape and structure of the evaporator in large equipment can be referred to the patent document CN103594127A. [0003] The flipping method adopted in the prior art is to pre-embed anchor components on the flip floor inside the reactor building, fix the f...

[0007] The third is to install the flip ring before the erection process, and remove the flip ring after erection, which requires a special removal device

[0014] (2) When using a dynamic overturning device, the equipment and the overturning device must be fixed together, making it difficult to assess safety;
