Abstract

The invention relates to a detection wheel support of steel rail ultrasonic flaw detector. The support comprises an outer frame, an inner frame, a swing angle adjusting mechanism and a transverse adjusting mechanism; the outer frame is connected with a flaw detector frame, and provided with a guide wheel set; the inner frame is arranged on the outer frame through a thread adjusting piece; the swing angle adjusting mechanism is transversely connected with the inner frame in a sliding mode, and the driving end of the swing angle adjusting mechanism is connected with a detection wheel set and adjusts the deflection angle of the detection wheel set relative to the transverse center surface of the steel rail; the transverse adjusting mechanism is transversely limited on the guide wheel set andcan vertically move relative to the guide wheel set, and the driving end of the transverse adjusting mechanism is connected with the swing angle adjusting mechanism and drives the swing angle adjusting mechanism to drive the detection wheel set to transversely move along the inner frame; the thread adjusting piece is screwed to adjust the vertical displacement of the inner frame, the swing angle adjusting mechanism, the transverse adjusting mechanism and the detection wheel set, so that the downward pressing amount of the detection wheel set relative to a steel rail tread is adjusted, after the downward pressing amount is adjusted to proper amount, the transverse adjusting mechanism and the guide wheel set are locked and fixed.

Description

technical field [0001] The invention relates to a detection wheel bracket of a rail ultrasonic flaw detector, which belongs to the technical field of rail ultrasonic flaw detection. Background technique [0002] At present, ultrasonic probe wheels have been widely used in rail flaw detectors. According to the requirements of ultrasonic flaw detection of rails, the detection wheel must maintain a certain amount of downward pressure and run at a certain angle on the top surface of the rail when it is working. Since the rail gauge often changes, if the detection wheel is simply fixed on the rail ultrasonic flaw detector, the detection wheel will deviate from the preset flaw detection position during the flaw detection process of the rail ultrasonic flaw detector due to the change of the gauge. [0003] At present, the follow-up structure of the probe wheel bracket is relatively complicated, and installation and subsequent maintenance are both troublesome. The position adjustm...
