Technical field
The present invention relates to steel rail flaw detection technology field, more particularly to a kind of probe flaw detection for the detection of rail flange of rail bottom surface
Control device.
Background technology
At present, it needs to detect a flaw to rail flange of rail bottom surface in the production process of rail, during flaw detection, the spy for structure of detecting a flaw
Head is coupled between flange of rail bottom surface by water realization, and rail is moved forward relative to probe and completed to whole section in the production line
The flaw detection of rail flange of rail bottom surface, rail need to be oriented to the charging of rail when moving forward, and prevent rail from deviateing probe
Corresponding flaw detection region；Meanwhile during flaw detection, flange of rail both sides set directive wheel, two directive wheels respectively with two side contacts of rail head
And be oriented to, the installation site of existing directive wheel is changeless, so that the distance between two directive wheels are changeless,
Cause flaw detection structure that can only detect a flaw to a kind of tread of width rail head, adaptability is bad, simultaneously as mechanical factor and steel
The straightness of the rail flange of rail is there are certain error, and directive wheel is fixed, therefore, is inevitably oriented to
Wheel is not reached with flange of rail side, and situation about being effectively oriented to cannot be formed by, which causing, occurs, and also will appear directive wheel and flange of rail side
Contact is excessive, the situation that rail examination traveling is caused interim card occur, have some setbacks, influence flaw detection process it is effective, be smoothed out.
In addition, during flaw detection, flaw detection structure is fixed in the left and right directions of rail, leads to the probe in flaw detection structure
Flaw detection cannot be servo-actuated in flange of rail bottom width direction；The installation site popped one's head in structure of detecting a flaw is also changeless, this is just
Resulting in can only detect a flaw to the flange of rail bottom surface of fixed width, and adaptability is bad；Due to the flatness of flange of rail bottom surface, there are one
Fixed error, therefore, inevitably gap is excessive between probe and flange of rail bottom surface, it is impossible to form efficient coupling, lead
It causes result of detection inaccurate, also will appear probe with flange of rail bottom surface against tension, probe wear-resistant block abrasion is caused to be accelerated, influences it
Service life.
