Regulating device for steel liner of nuclear island

Abstract

The invention relates to a regulating device for a steel liner of a nuclear island. The regulating device for the steel liner of the nuclear island comprises a regulating post, a first regulating mechanism, second regulating mechanisms and third regulating mechanisms, wherein one end of the first regulating mechanism is connected with the regulating post while the other end acts on a barrel body through regulating bolts, one end of each second regulating mechanism is connected with the regulating post while the other end acts on back rib angle steel of the steel liner through a connecting bracket, and one end of each third regulating mechanism is fixed with the regulating post while the other end acts on the back rib angle steel of the steel liner through a locking device. One first regulating mechanism, two second regulating mechanisms and two third regulating mechanisms are arranged along the axial direction of the regulating post in sequence. According to the regulating device for the steel liner of the nuclear island, the connection is adjustable and detachable, and accordingly the construction time is effectively shortened; after improving the regulating device, the regulating device can be used repeatedly, and accordingly the construction cost is effectively reduced; the upper mouth of the wall plate of the steel liner is provided with a regulating node device capable of effectively and precisely regulating the overall dimension of the upper mouth of the wall plate of the steel liner, the mounting precision is improved, the construction time is shortened, and the construction safety is increased.

Description

technical field [0001] The invention relates to an adjustment device applied to the steel lining of a nuclear island, in particular to an adjustment device applied to the steel lining of a nuclear island that improves the construction level of the steel lining of a nuclear power plant and is more economical, efficient and safe. Background technique [0002] With the continuous development of my country's nuclear power industry and the continuous maturity and system of nuclear power construction technology, nuclear power construction enterprises need to continuously optimize, upgrade and innovate nuclear power construction technology. The steel lining adjustment device plays the role of supporting the hoisting and positioning of the steel lining single component. [0003] The methods currently used at home and abroad: [0004] The connection method adopted by each node is directly welded and fixed, which cannot be adjusted in time. Its shortcomings are as follows: [0005]...

AI Technical Summary

Problems solved by technology

[0005] 1. The several nodes set up only play the role of connection and fixation, and cannot meet the requirements of timely and effective adjustment of steel lining wall panels during installation;

[0006] 2. The connection between each node and the adjustment column is welded, and most of the welding must be performed on site

This connection method is difficult to construct, has low efficiency, and is not easy to adjust and disassemble. It cannot effectively adjust the steel lining wall panels, and the adjustment device cannot be used for multiple times, which increases the installation process and affects the construction efficiency.
