AI Technical Summary

Technical Problem

When the clamping mechanism of traditional steam turbine maintenance devices fluctuates pressure and handles parts of different shapes and sizes, the clamping force is unstable, the operation is complicated, and it is difficult to meet the needs of different components, which limits the maintenance efficiency.

Method used

An inspection device including a mobile station, a slide rail, a moving mechanism and a clamping mechanism is designed. The moving mechanism realizes flexible adjustment of the position of the clamping mechanism through the combination of bidirectional threaded rod, adjustment block, connecting rod and slide plate; the clamping mechanism adopts the design of mobile block, threaded column and hydraulic rod to achieve accurate positioning and fixing of the maintenance objects.

Benefits of technology

The device can be flexibly adjusted in different positions and sizes of steam turbines, improving maintenance efficiency and accuracy, reducing the difficulty of manual operation, and through the control of the hydraulic rod, the risk of damage caused by excessive or too small clamping force is avoided.

Abstract

The embodiment of the invention provides an overhauling device for a steam turbine of a thermal power plant. The sliding rails are symmetrically distributed on the two sides of the top of the moving table; the supports are symmetrically distributed at the two ends of the movable table. The moving mechanism is arranged at the bottom of the bracket; the moving mechanism comprises a two-way threaded rod, an adjusting block, a connecting rod and a sliding plate; the adjusting blocks are symmetrically distributed at the two ends of the bidirectional threaded rod, the connecting rods are fixedly connected to the tops of the adjusting blocks, and the two ends of the connecting rods are connected with one side of the sliding plate. The clamping mechanism is arranged at the top of the bracket; the clamping mechanism comprises a moving block, a first clamping block, a second clamping block, a threaded column and a hydraulic rod. The moving block is fixedly connected to the side face of the first clamping block, the threaded column is in threaded connection with the moving block, and a hydraulic rod is fixedly connected to the top of the second clamping block. The device can be flexibly adjusted at different positions, and is suitable for maintenance work of turbines of different sizes and types. Therefore, the maintenance process is more efficient and convenient.
