Abstract
The utility model belongs to a rail detecting device for railways. The main purpose is to overcome the defect that a single zero degree ultrasonic probe has no 'locking hole' function and is easy to send out false alarm when encountering rail holes. The double zero degree probe rail flaw detector mainly comprises ultrasonic probes and an operation display part, wherein, a probe part comprises two ultrasonic probes which are arranged in front and back direction along the rail direction and are perpendicular to the surface of the rail. The distance between the two probes us larger than the diameter of a rail hole of the rail, and is capable of being 35 to 45 mm and is adjustable.
Description
The utility model belongs to the track checkout equipment, mainly proposes a kind of pair of zero degree probe rail flaw detector.
In the track checkout equipment, mainly adopt ultrasonic technology to be used for the flaw detection of rail at present.In " steel rail ultrasonic flaw detecting " (author wears grand celebration, Ou Yangtianshun), the major technique of present steel rail ultrasonic flaw detecting has been done introduction, comprising 37 ° of probe detection methods and 0 ° of probe detection method.Wherein 37 ° of probe detection methods can detect the rail porous dehiscence line of 2mm, but have the following disadvantages: 1, detection faces is required harsh, at tread, press fall into, under scratch or the unequal situation of swabbing, because of " sound travel " blocking-up " is walked sky ".When 2, the crackle inclination angle was departed from probe orientation or flaw echo and do not constituted " corner angle reflection ", popping one's head in all can not receive echo.3, the detection sensitivity to palatine plane fracture line is low especially.0 ° of probe detection method is about to ultrasonic probe and tested rail is in the same plane, it has overcome some deficiency of 37 ° of probes, to detecting rail palate plane fracture and flange of rail splitting its distinctive feature is arranged, but it does not possess " lockhole " function, when promptly detecting rail rail hole, do not have crackle even the rail hole is intact, provide easily yet and warn, thereby limited applying of it.
The purpose of this utility model is to propose a kind of pair of zero degree probe rail flaw detector, makes its characteristics with high measurement accuracy, overcomes the existing defective of single nullity probe rail flaw detector.
The utility model is finished the technical scheme that its invention task proposed: it mainly comprises ultrasonic probe, the operation display part branch; Probe segment comprises two ultrasonic probes, and two ultrasonic probes are along the setting of rail direction front and back and perpendicular to the rail surface; Spacing between two probes is greater than the diameter in rail rail hole, can be 35～45mm and can adjust.
The utility model ultrasonic probe working method is the pulse penetration.Its flaw detection mode such as accompanying drawing 2.When the complete flawless in rail rail hole, two probe A, B lay respectively at before and after the rail hole along the time, A, B all can receive end ripple, instrument is normal, does not report to the police.When the complete flawless in rail hole, the sound travel of probe B is cut off by the rail hole, and probe A is received end ripple, and this moment, instrument was also normal, did not report to the police.When rail hole generation crackle, probe A, B sound travel all are cut off, and instrument shows hurt and reports to the police.This shows that " lockhole " function is to be placed in 0 ° of probe mode operating under the sequential relationship by two by ad hoc fashion to finish.
The utility model has been finished the flaw detection at place, rail hole in the rail examination preferably, can not report by mistake intact rail hole, and all can accurately quote for the crackle greater than rail hole projected length 5mm, and flaw detection effect is stable.
Embodiment:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the two zero degree probe of the utility model working method figure.
The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:
As shown in Figure 1, the utility model mainly comprises ultrasonic probe 6, and operation display part divides 2; And comprise hairbrush 5 and water bottle 4; Hairbrush 5 is in order to remove rail surface foul, and the water in the water bottle is coated on the rail equably by hairbrush, strengthens hyperacoustic coupling effect.Wherein, probe segment comprises that 6, two ultrasonic probes 6 of two ultrasonic probes are provided with before and after the rail direction and perpendicular to the rail surface, and the spacing between two probes can be 35～45mm, and can adjust greater than the diameter in rail rail hole.In the utility model defectoscope except that two zero degree ultrasonic probes being set and being provided with the structure, all the other structures such as operation display part branch, running gear is all identical with existing steel rail ultrasonic flaw detecting instrument structure with structures such as hairbrush, water bottles.1 is hand holding handle among the figure, and it is a box body structure, internal battery, 3 is handspike, operation display part divide 2 and water bottle body 4 be provided with on it, 7 are card wheel, it is close to rail one side, thereby guarantees that the defectoscope front portion is positioned at plane on the rail, and guarantees that ultrasonic probe 6 is vertical with rail.
