Tool and method for measuring dynamic and static positions during dismounting of false tile of zero-bearing support medium-pressure cylinder

The invention relates to the technical field of turbine installation, in particular to a tool and a method for measuring dynamic and static positions during dismounting of a false tile of a zero-bearing support medium-pressure cylinder. The invention discloses a tool for measuring dynamic and static positions during dismounting of a false tile of a zero-bearing support medium-pressure cylinder, and the tool comprises a positioning arc block which is fixedly disposed on a steam seal body at the end part of the medium-pressure cylinder through a bolt. The radial clearance between the intermediate pressure cylinder and the rotor can be directly measured without using a dial indicator to measure the radial clearance between the intermediate pressure cylinder and the rotor in a narrow space between the intermediate pressure cylinder and the bearing box. 本公开涉及汽轮机安装技术领域，具体的涉及零轴承支撑中压缸假瓦拆除时动静位置测量工装、方法。本发明公开了一种零轴承支撑中压缸假瓦拆除时动静位置测量工装，包括定位弧块，定位弧块通过螺栓固定安装于中压缸端部的汽封体上。能够避免在中压缸与轴承箱之间狭小的空间内使用百分表测量中压缸与转子之间的径向间隙，直接测量定位弧块与转子之间的径向
