Embodiment Construction

[0061] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0062] The turning and erecting of the main system equipment of a nuclear power plant is one of the most important procedures in the installation of a nuclear power plant, and is the main critical path for the construction of a nuclear power plant. Due to the importance and sensitivity of nuclear-grade equipment, the safety of its flipping process has been paid much attention. The invention provides a turning and erecting device for an evaporator, which overcomes the technical prejudice on the spot and ...

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...
