Problems solved by technology

[0003] The purpose of the present invention is to provide an auxiliary lifting device for the assembly of the high-pressure valve of the steam turbine, so as to solve the problem that the existing lifting method when the high-pressure regulating valve of the steam turbine is assembled is directly tied with a sling for lifting, and there is a large amount of preparation work before lifting, and the lifting process is difficult. It is not stable, which leads to potential safety hazards, and the clamping force is not enough, so that the lifting rope is easy to loosen, resulting in bumping and damage to the high-pressure regulating valve of the steam turbine

Abstract

The invention provides an auxiliary hoisting device applied to the assembly of a turbine high-pressure valve, relates to an auxiliary hoisting device applied to the assembly of a turbine valve, and aims to solve the problems that when the conventional turbine high-pressure regulating valve is directly bundled by lifting ropes to be hoisted during valve assembly, the preparation workload before hoisting is large, the hoisting process is unstable, so that the potential safety hazard is easy to generate, and the clamping force is insufficiently large, the lifting ropes are easy to loosen and the valve is bumped and damaged. A mold cavity of an upper shell horizontally penetrates through the upper shell, a mold cavity of a lower shell horizontally penetrates through the lower shell, the upper shell and the lower shell are adhered, the mold cavity of the upper shell and the mold cavity of the lower shell are arranged oppositely, the upper shell and the lower shell are connected, an upper lining tile is fixedly connected with the interior of the mold cavity of the upper shell, a lower lining tile is fixedly connected with the interior of the mold cavity of the lower shell, the upper lining tile and the lower lining tile are arranged oppositely, a turbine high-pressure valve is respectively matched with the upper lining tile and the lower lining tile, and a lifting lug I and a lifting lug II are fixedly connected with the top of the upper shell. The auxiliary hoisting device disclosed by the invention is applied to the hoisting of the turbine high-pressure valve.

Description

technical field [0001] The invention relates to an auxiliary lifting device for steam turbine valve assembly. Background technique [0002] The structure of the steam turbine high-pressure regulating valve is complex and consists of many parts, including many shafts and sleeves. The existing lifting method when assembling the high-pressure regulating valve of the steam turbine is directly tied up with a sling for lifting. Since the high-pressure regulating valve of the steam turbine does not have a lifting fixed point, the preparation workload before lifting is heavy, and the lifting process is not stable, resulting in potential safety hazards and clamping. If the force is not enough, the lifting rope is easy to loosen and the high-pressure regulating valve of the steam turbine is bumped and damaged. Contents of the invention [0003] The purpose of the present invention is to provide an auxiliary lifting device for the assembly of the high-pressure valve of the steam tur...
