Abstract
The invention discloses a probe-testing undercarriage for detecting a steel rail waist. The undercarriage comprises two L-shaped supporting arms (1), a probe mounting plate (2), a guide wheel fixing frame (3), a guide wheel (4) and a universal device (5). In the undercarriage, the probe mounting plate (2) for mounting a probe is connected with the two L-shaped supporting arms (1) by the universaldevice (5); the balance action of a tension spring to the probe-mounting plate (2) is adopted, and thus the probe mounting plate (2) can adjust a self position according to a concrete arc surface of the steel rail waist to tightly match and follow a detection surface in the detection process so as to ensure favorable contact between the probe and the steel rail arc surface to be tested, lessen theclutter reflection, relatively improve the surplus sensitivity, the resolution and the signal-to-noise ratio, reduce a missing report rate and an error report rate, ensure the accuracy and the reliability of a testing result and the running safety, prolong the service life of the probe by lessening the overquick abrasion of a probe abrasion-resistant block, decrease the cost and increase the effect.
Description
Technical field
The present invention relates to a kind of probe flaw detection undercarriage that the rail web of the rail detects that is used for.
Background technology
At present, in the production run of rail, need the rail web of the rail is carried out line flaw detection, being used to the flaw detection undercarriage of popping one's head in the actual detected in the defect-detecting equipment can not servo-actuated, and the probe installing plate that is used to install probe is fixed equally, probe is irremovable in detection, the probe of defect-detecting equipment is resisted against rail web of the rail face and between to be detected and is coupled by water during detection, finishes flaw detection to whole section rail web of the rail face by rail flowing on production line.Because there is certain error in the flatness of mechanical factor and rail itself, the probe of existing defect-detecting equipment is again fixed as described above, caused the excesssive gap between in the flaw detection process some rail section web of the rail face and the probe, can not be coupled fully, cause Lou spy, mistake to visit and make result of detection inaccurate.
Some section can cause the enhance faster wear of the wear-resistant block of popping one's head in against tension when simultaneously the cambered surface of rail web of the rail face made with the contacting of probe wear-resistant block, and had influence on the serviceable life of probe.
