Abstract
The utility model provides a portable lossless rail flaw detector used for the invaliding detection of cracks of various railway rails. The body of the device adopts an ultrasonic probe, a luminous tube, a loud-speaker two-way alarm display system in the prior art, a swabbing mechanism adopts a rotary wheel type structure, a centering mechanism and an aligning mechanism, and besides, a lifting handle and a pushing handle on the body are added. Thus, a folding type link mechanism can be made. The utility model has the advantages of compact structure, small size and convenience for carrying. Besides, the utility model can prevent phenomena of false alarm and alarm leakage generating. The portable lossless rail flaw detector obviously improves the efficiency of the site operation and the detection result.
Description
The utility model relates to a kind of portable rail harmless flaw detector that is used for the sick and wounded detections such as slight crack of all kinds of rail, is applicable to that particularly the rail that industries such as railway, mine are used carries out the nondestructive examination detector.
At present, be the transportation safety of industries such as protection railway, mine, often the rail to its use carries out nondestructive examination.Existing harmless flaw detector adopts and pulls scrubbing brush formula swabbing device because of the swabbing mechanism in its structure, causes the instrument complicated integral structure, bulky, show the field boundary operation and carry all inconvenience, it is irregular particularly to pull the scrubbing brush swabbing, easily makes detection mistakes such as warning, display system produce and fail to report, wrong report.Do not have centering, core-regulating mechanism during in addition owing to the field boundary operation now of this instrument, can not arbitrarily adjust the ultrasonic probe position.Therefore, can't determine the relative position of defectoscope body reliably, influence the effect of carrying out flaw detection apart from rail.
The purpose of this utility model provides a kind of improved rail harmless flaw detector, and it is compact conformation not only, and volume is little, in light weight, existing field boundary operation and carry all easily, and the generation that can prevent false alarm, fail to report alert phenomenon obviously improves the effect that shows field boundary efficiency of operation and carrying out flaw detection.
The purpose of this utility model is achieved in that the body of this device still adopts ultrasonic probe of the prior art, luminotron and the warning of loudspeaker two-way, display system, its swabbing mechanism adopts spinning roller formula structure, bristle is annular, and annular spinning roller water brush is integral with driving wheel group by travelling wheel and actuator drives.Be packed in the centering machine that the travelling wheel utilization of body lower running mechanism is made up of locating wheel and stretching pulley, be positioned the rail rail level.For carrying and showing the field boundary operation conveniently, handle and pushing hands on the body can be made into accordion structure, and handle and pushing hands after folding lock by lock pin.Travelling wheel is positioned the rail rail level by centering machine, just can detect reliably.
Because the utility model adopts spinning roller formula swabbing mechanism, has overcome the existing deficiency that pulls scrubbing brush formula swabbing device, guarantees the homogeneity of swabbing, has prevented sneaking into of misoperation signal effectively, detection mistakes such as avoiding reporting by mistake, fail to report.Water brush and probe can arbitrarily be adjusted the position of probe according to actual needs.Travelling wheel utilizes centering machine to be positioned the rail rail level simultaneously, and the core-regulating mechanism of setting and centering machine are determined the relative position of defectoscope body apart from rail reliably, can make the detection effect reach best.Again because of its volume is little, existing field boundary operation and carry all very convenient, so can obviously increase work efficiency.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure synoptic diagram of the utility model.
Fig. 2 is the core-regulating mechanism synoptic diagram of swabbing mechanism of the present utility model and probe.
Fig. 3 is the centering machine structural representation of the utility model travelling wheel.
Describe concrete structure of the present utility model and working condition in detail according to Fig. 1-3.This device comprises body and is assembled in ultrasonic probe on the body that luminotron and loudspeaker two-way are reported to the police, display system, travel mechanism and swabbing mechanism and centering machine and core-regulating mechanism.Wherein ultrasonic probe, luminous pipeline and loudspeaker two-way alarm display system all adopt prior art, and its structure and detection principle no longer describe in detail.The travelling wheel 17 that is installed in the body lower running mechanism utilizes centering machine to be positioned rail 19 rail levels.This centering machine by stretching pulley 12, spring 13, locating wheel 10 and 16 and wire rope 9 form.Locating wheel 10 and 16 is close on the side 20 of rail 19, and stretching pulley 12 is pressed on the another side 18 of rail 19 by the effect of spring 13.As meeting fork, an available end is fixed on the tensioning handgrip 5, the other end is fixed on the wire rope 9 on the stretching pulley 12 in the operation, and stretching pulley 12 is counterclockwise rotated around the shaft, leaves rail level 18, just defectoscope can be smoothly by road fork place.Swabbing mechanism adopts adjustable spinning roller formula structure, this swabbing mechanism comprise spinning roller water brush 15 and with its assembling all-in-one-piece power wheel 25 and device for storing liquid (not drawing in the accompanying drawing).Its spinning roller water brush 15 bristles that are annular can be applied to the homogeneous media in the device for storing liquid rail 19 surfaces.Power wheel 25 drives by travelling wheel 17 and one group of cogwheel gearing (or belt transmission) of travel mechanism, the power wheel 25 that rotates just drives 15 rotations of spinning roller water brush homogeneous media is painted on the rail surface, the ultrasonic probe 11 that is assembled on the suspension 14 is imported alarm display system with detectable signal, can measure the operating mode of rail 19.Adjustable spinning roller water brush 15 is positioned on the same core-regulating mechanism with the suspension 14 that ultrasonic probe 11 is housed, and this core-regulating mechanism is made of aligning knob 22, aligning elbow 23, aligning axle 24.Wherein an end of aligning elbow 23 and suspension 14 and spinning roller water brush 15 all be positioned can axially movable aligning axle 24 on, the other end spiral marking connection of knob 22 and aligning elbow 23, rotation aligning knob 22 drives aligning elbow 23 and moves axially, and then drive aligning axle 24 moves axially together with location probe 11 and spinning roller water brush 15 thereon.Like this, utilize this core-regulating mechanism and centering machine, can arbitrarily adjust the relative position of ultrasonic probe 11 and spinning roller water brush 15 and rail 19 according to actual needs, guarantee the optimum efficiency that detects.For ease of carrying and operation, handle on the utility model body and pushing hands can be made into collapsible link gear, and this mechanism comprises support 6, the handle 2 that has back of the body ring 1,3 and pushing hands 4, handgrip 5, wire rope guide wheel 7 and the rotating shaft 8 that utilizes tensioned.Wherein tensioning handgrip 5 is fixed with wire rope 9, by guide wheel 7 other end of wire rope 9 is fixed on the stretching pulley 12 of centering machine.Utilize tensioning handgrip 5 to drive wire rope 9, stretching pulley 12 is counterclockwise rotated around the shaft, leave rail level 18.When carrying, folding rack 6 rotates counterclockwise back (among Fig. 1 shown in the fine line) around axle 8, with lock pin 21 lockings, can utilize handle 2 to carry easily, also can on back of the body ring 1,3 braces be set and carry.
