Abstract

The invention discloses a probe frame centering device for track steel rail weld flaw detection, a probe frame is located below a centering frame, the top of the probe frame is connected with the bottom of a Y-axis angle deflection device, the top of the Y-axis angle deflection device is connected with a top plate of the centering frame, and the Y-axis angle deflection device is used for self-adaptive adjustment in the Y-axis direction; a Z-axis rotating device is arranged at the top of the centering frame, and a center shaft at the top of the centering frame penetrates through a rotating motor of the Z-axis rotating device to be fixed to the Z-axis rotating device. An X-axis angle deflection device is fixed to the top of the Z-axis rotating device and used for self-adaptive adjustment in the X-axis direction. And meanwhile, a Y-axis moving assembly and a height lifting assembly are sequentially arranged at the top of the X-axis angle deflection device and are used for self-adaptive adjustment in the Y-axis direction and the height direction correspondingly. According to the centering device, self-adaptive adjustment in three directions can be achieved, centering attachment of the probe frame under various working conditions can be guaranteed, the problem that a conventional probe frame is manually adjusted is solved, and the welding seam detection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of rail flaw detection equipment, and in particular relates to a probe frame centering device used for rail rail weld flaw detection. Background technique [0002] With the increase of train speed and axle load, coupled with the thermal expansion and contraction of metal due to environmental reasons, the in-service rails are subjected to repeated rolling by the wheels for a long time. In order to ensure the safe operation of the locomotive, it is necessary to frequently inspect the in-service rails. Detection, timely detection of damage existing in the rail, so that timely remedial measures can be taken. [0003] The rail flaw detection in my country mainly adopts ultrasonic detection. The ultrasonic rail flaw detection device is a rail flaw detection device that detects the rail damage according to the ultrasonic echo reflected by the rail damage. When the ultrasonic rail flaw detection vehicle uses the ul...
