AI Technical Summary

Technical Problem

Existing technologies make it difficult to effectively drive the motor to move within the confined space of the secondary side of a steam generator and transmit the motion to the electrode plates for electrical discharge machining. Furthermore, traditional mechanical cutting carries the risk of damaging the heat transfer tubes.

Method used

A flexible transmission system was designed, including a head transmission mechanism, a flexible transmission mechanism, and a tail drive mechanism. The motor motion outside the motor is transmitted to the electrode plate through the flexible transmission structure to realize the reciprocating feeding motion of the electrode plate.

Benefits of technology

It achieves effective motion drive of electrode plates in a narrow area, reduces head weight and volume, avoids damage to heat transfer tubes, and realizes remote flexible transmission.

Abstract

The application relates to a flexible transmission system of a steam generator secondary side metal foreign matter cutting tool, characterized in that the flexible transmission system comprises a head transmission mechanism, a flexible transmission mechanism and a tail driving mechanism, the head transmission mechanism is sequentially connected with the flexible transmission mechanism and the tail driving mechanism. The flexible transmission system of the steam generator secondary side metal foreign matter cutting tool transmits the movement of a motor arranged outside a steam generator to an electrode sheet between steam generator pipes and drives the electrode sheet to make reciprocating feeding movement.
