AI Technical Summary
Technical Problem
During the steam turbine maintenance process, it is difficult for laser trackers to directly measure certain deep or narrow areas in the cylinder, such as blade top steam sealing teeth.
Method used
A cylinder measurement auxiliary device is designed, including a central connecting base and a fixing assembly. By setting multiple connecting ends and target balls, indirect measurement of positions that cannot be directly observed by the laser tracker.
Benefits of technology
The device determines the spatial coordinates of the measuring parts through the spatial coordinates of multiple target balls, thereby achieving accurate measurement of deep or narrow areas, shortening maintenance time and improving maintenance quality.

Abstract
The utility model relates to the technical field of steam turbine maintenance, in particular to an auxiliary device for measuring a cylinder, which comprises a central connecting seat and a fixing assembly, the central connecting seat comprises a measuring end and at least three connecting ends, and the axis extension lines of the at least three connecting ends are not in the same plane. Each connecting end is fixedly connected with a connecting rod, the end part of each connecting rod is fixedly connected with a target ball, the measuring end is fixedly connected with a measuring rod, the end part of the measuring rod is provided with a measuring piece, and the measuring piece is used for being in contact with a to-be-measured part of the cylinder. When the measuring piece is in contact with the to-be-measured part, the position of each target ball is unique and determined, so that the uniquely determined space coordinate of the measuring piece can be jointly determined through the space coordinates of the at least three target balls, the space coordinate of the to-be-measured position is further obtained, and the position which cannot be directly observed by the laser tracker is measured.
