- Abstract
In this paper, the cause of the fault of detection rod gap jamming at the second traction point of the S700K switch machine on the main line of Ningbo Rail Transit Line 1 is analyzed. Due to the design gap between the frog rail and the base rail at the second traction point, it is not close to each other actually. The frog rail and the switch equipment are more susceptible to vibration, shock, etc., coupled with the combined action of poor working conditions, rail crawling and other additional factors, resulting in the detection rod position deviation, and then lead to detection rod gap jamming fault. Based on the fact that the actual condition of the turnout is diffi cult to change, a scheme for transforming the detection rod at the second traction point is proposed, and through fi eld test demonstration, it can well meet the needs of field use and improve the stability of the switch equipment operation.
