Automatic acquisition device for stator positioning rib welding deformation measurement data

Abstract

The invention discloses an automatic acquisition device for stator positioning rib welding deformation measurement data. The automatic acquisition device comprises a probe, a probe fixing support, a signal acquisition device, a terminal computer, automatic analysis software, output equipment, an alarm device and monitoring supports, wherein each monitoring support is composed of a support fixing frame, a support base and a support walking mechanism and is fixed to a lower annular plate of a stator annular plate; the probe fixing support comprises a supporting block, an adjustable cushion blockand a probe frame, the supporting block is welded and fixed to the support fixing frame, the adjustable cushion block is installed on the supporting block, the probe frame is welded and fixed to thefront end of the adjustable cushion block, and the probe is fixed to the probe frame; the signal acquisition device and the alarm device are fixed on a support base and are connected with the terminalcomputer through signals; the signal acquisition device is connected with the probe; and the terminal computer is provided with the automatic analysis software. The automatic acquisition device can perform automatic measurement, automatic recording, automatic analysis and real-time alarm, and can perform real-time monitoring when a stator positioning rib of a hydro-generator is welded.

Description

Technical field: [0001] The invention relates to the technical field of hydropower station unit equipment assembly, in particular to an automatic collection and automatic alarm device for welding deformation data of positioning ribs assembled on-site laminated stators. Background technique: [0002] The stators of large-scale hydro-generator sets arrive in parts and are assembled into a whole through a series of processes on the construction site. The installation of positioning ribs is one of the most critical processes in stator assembly, and its quality will directly affect the stator assembly. One process - the quality of stator core stacking, as the standards for safe operation of hydropower stations and power grids continue to improve, the standards for key data such as radius and roundness of on-site laminated stator assembly are also getting higher and higher, and the installation of positioning ribs is used as stator assembly Even in the process with the highest pre...

Problems solved by technology

[0005] (3) Welding deformation control: The welder cannot monitor and check whether deformation occurs in real time during the welding process

[0011] 2) Dimension measurement is required for each welding process and each welding block. The measurement is interspersed with the welding process, and the number of measurements is large, which directly affects the continuity of welding and prolongs the welding period.

[0012] 3) The size measurement of the welding process in each process is affected by manual intervention, level deviation, etc., making measurement difficult, poor accuracy, long measurement cycle, large amount of data, and difficult analysis
