TEST BENCH FOR CONTACTLESS ULTRANSONIC QUALITY CONTROL OF RAILS

EKSPERIMENTAL'NYI STEND DLIA BESKONTAKNOGO UL'TRAZVUKOVOGO KONTROLIA KACHESTVA REL'SOV

Practical achievement of a contactless means of rail inspection is possible only with the mechanized or automatic process of control. For this purpose a test bench has been worked out in the scientific Research Institute of Bridges of the Leningrad Lenin Order Institute of Railroad Transportation Engineers named after Academician V.N. Obraztsov. The bench contains two fundamental functional assemblies: a mechanical portion (mechanism for extension and fixation of the rail, and a magnetic biasing system with a mechanism for fixing the electromagnetic- acoustic inspection system) and an assembly stand with electronic apparatus. The location of the entire equipment complex is envisaged to be in the same place where operations are carried out. This allows control before the beginning of the welding, and rejection of rails with defects in their basic metal, and secondly, utilization of the mechanism for extension and firm fixation of the rails on the table of a planing machine. The figures include a block plan of the electronic portion of the bench, and a kinematic plan of the bench.
