Title
(EN) AUTOMATIC ULTRASONIC DETECTION DEVICE FOR RAILS
(FR) DISPOSITIF DE DÉTECTION AUTOMATIQUE PAR ULTRASONS POUR RAILS
(KO) 레일용 자동 초음파 탐지장치
Abstract
(EN)
The present invention relates to an automatic ultrasonic detection device for rails. More specifically the invention relates to an automatic ultrasonic detection device for rails which: inspects for cracks in a welded portion which connects a rail and a neighboring rail while automatically being moved between the rails; and is maintained in a parked state between the rails when not inspecting for cracks. To achieve said objective, the invention comprises a main body portion, a wheel portion installed at both sides of the main body portion, an operation portion which is installed in the main body portion and operates the wheel portion, and a power transfer portion which provides power to the operation portion.
(FR)
Cette invention concerne un dispositif de détection automatique par ultrasons pour rails, et plus spécifiquement, un dispositif de détection automatique par ultrasons pour rails qui : recherche les fissures dans une partie soudée qui relie un rail à un rail voisin et se déplace automatiquement entre les rails ; et est maintenu à un état stationnaire entre les rails quand il ne recherche pas de fissures. Pour atteindre ledit objectif, l'invention comprend une partie corps principal, une partie roues située de part et d'autre dudit corps principal, une partie fonctionnement logée à l'intérieur dudit corps principal, et une partie transfert d'énergie qui fournit l'énergie nécessaire à la partie fonctionnement.
