An adjustment device applied to nuclear island steel lining

Abstract

The invention relates to an adjustment device applied to a steel lining of a nuclear island, comprising: an adjustment column, one end is connected with the adjustment column, the other end is connected with a first adjustment mechanism through the adjustment bolt and the cylinder, one end is connected with the adjustment column, and the other end is connected with the adjustment column. A second adjusting mechanism for connecting the bracket and the steel lining back rib angle steel, and a third adjusting mechanism for fixing one end to the adjusting column and the other end acting with the steel lining back rib angle steel through a locking device. A first adjustment mechanism, two second adjustment mechanisms, and two third adjustment mechanisms are sequentially arranged along the axial direction of the adjustment column. The connection method of the invention is improved to be adjustable and detachable, which effectively shortens the construction time; after the adjustment device is improved, it can be reused and the construction cost is effectively reduced; an adjustment node device is added at the mouth of the steel lining wall plate , It can efficiently and accurately adjust the overall size of the opening of the steel lining wall panel, which not only improves the installation accuracy, but also shortens the construction time and increases the safety of the construction.

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.
