Abstract
The utility model discloses a steel rail crack detection instrument, which consists of detection heads, a detection host machine, a push-pull support frame, rolling wheels, connecting pipes and fixing rings, wherein both sides of the lower end of the push-pull support frame are respectively and fixedly connected with the two detection heads at the front side and the back side through the connecting pipes, both sides of each detection head are respectively fixed with the rolling wheels, the detection host machine is fixedly connected onto the upper connecting pipe arranged in the middle of the push-pull support frame through the two fixing rings, and the detection heads are electrically connected with the detection host machine. Because an eddy current sensor is adopted for carrying out crack detection, the sensitivity is high, in addition, the tiny cracks of a steel rail can be detected, in addition, the structure of a detector is simple, the use is convenient, in addition, the simultaneous double-rail detection is adopted, the detection efficiency is greatly improved, the two detection heads are arranged at the front side and the back side of each steel rail, the omission rate is greatly reduced, and the steel rail crack detection instrument belongs to an economical and applicable steel rail crack detection instrument for railway departments at present.
Description
Technical field
The utility model relates to a kind of crackle detecting instrument, relates in particular to a kind of rail cracks detector, belongs to the application of electronic technology technical field.
Background technology
Along with development and national economy, transportation by railroad is very important, and rail failure is the principal element that influences safety of railway traffic, the domestic main at present daily detection that relies on the workman that inspects the road, though work out some detecting instruments, not that sensitivity is low exactly can only detection of broken and can not detect crackle yet.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of rail cracks detector, adopts eddy current sensor to carry out crack detection, and is not only highly sensitive but also can detect the microcrack of rail.
The technical solution of the utility model is: the rail cracks detector, it is made up of detection head, detection main frame, push-and-pull support, roller, connecting pipe, set collar, both sides, push-and-pull support lower end are respectively by fixedly connected two detection heads before and after the connecting pipe, each detection head both sides all is fixed with roller respectively, be connected with the detection main frame by two set collars on the last connecting leg in the middle of the push-and-pull support, detection head is electrically connected with the detection main frame.Described detection head is to be fixed with eddy current sensor by fixed mount in the enclosure, also is fixed with excitation signal generator and detection signal amplifier on fixed mount respectively, and the detection signal amplifier is electrically connected with the signal converter that detects main frame.Described detection main frame is that signal converter is electrically connected with message handler, and message handler is electrically connected with LCD, voice guard, optical display unit respectively.
The beneficial effects of the utility model are: owing to adopt eddy current sensor to carry out crack detection, not only highly sensitive but also can detect the microcrack of rail, and pick-up unit is simple in structure, easy to use, and adopt double track to detect simultaneously, improved detection efficiency greatly, establish two detection heads before and after the every rail, having significantly reduced loss, is the rail cracks detector that the current rail sectional is suitable for.
