Description
Technical field
The present invention relates to the technical field of track detection, more particularly, to a kind of track defectoscope and with track defectoscope
Inspection car.
Background technology
Track flaw detection refers to that the rail head of rail and the fatigue failure and weld defect of web of the rail position are entered using defect-detecting equipment
Row detection, the content for being detected including track scratch, crushing of rail head, flange of rail corrosion and crescent moon chip off-falling etc., when the defect-detecting equipment
When sliding in orbit, it becomes possible to which hurt signal, mileage signal and line characteristics signal to rail are recorded, testing staff
According to the information that defect-detecting equipment is recorded, can quickly determine the position of track defect, and hurt size, and also can
To determine the circuit mileage of track defect, using above-mentioned track detection method, track defect position can be in time found, and and
Shi Xiuli, to ensure that train drives safely on intact track, so as to avoid the occurrence of unnecessary security incident.
When track flaw detection is carried out, staff needs to be carried to defectoscope on track, flaw detection wheel is slided in orbit
OK, track could accurately be detected a flaw, during defectoscope is carried, because the weight of defectoscope is relatively sunk, it is necessary to many
Name staff carries, and in order to save strength, using wheel of detecting a flaw defectoscope will be made to slide on the ground, but which increase
Detect a flaw wheel access times, staff when flaw detection operation is carried out to track, flaw detection wheel need always with rail contact, flaw detection
, it is necessary to transport defectoscope after finishing, in order to save manpower, staff can utilize the slip between flaw detection wheel and track to promote and visit
Hinder instrument, flaw detection wheel is increased with the frequency of exposure of track, the abrasion for easily causing flaw detection wheel surface is used for a long time；It is existing
Have in technology, gap easily occurs in flaw detection wheel contact between track, contacts insecure, and the side with track is taken turns in especially flaw detection
Easily there is skew in face, so as to cause flaw detection wheel and be contacted between track loosely, causes flaw detection data inaccurate；And used
Defectoscope a piece track can only be detected a flaw, it is impossible to while to the flaw detection of two tracks, thus extending the activity duration, lead
Cause inefficiency.
Inspection car of the prior art, when being detected a flaw to track using above-mentioned defectoscope, uses the number of times mistake of flaw detection wheel
It is many, cause to install unstable, it is also easy to cause flaw detection data inaccurate.
The content of the invention
It is an object of the invention to provide a kind of track defectoscope, to solve present in prior art, defectoscope is turning
During fortune, in order to save manpower, flaw detection wheel needs constantly to be contacted with ground, or and rail contact, the flaw detection wheel
Surface easily causes abrasion, the technical problem of influence flaw detection measurement data.

Device 14 is compressed to support meanss 12, so that flaw detection wheel 13 compresses track operation.
The upper end of the hold-down gear 14 is attached using bolt, nut and pad through the first support frame 111, described
The lower end of hold-down gear 14 is connected in the groove of the upper surface of the second support frame 112, hold-down gear 14 is in the first support frame
111 and second between support frame 112, when second support frame 112 is moved downward, drive the left end of the 3rd support frame 121 to
Lower motion, the pressure of hold-down gear 14 is moved downward and is released, and now, the right-hand member control support body of the 3rd support frame 121 will be visited
Wound wheel 13 falls, and runs the laminating track of flaw detection wheel 13, it is ensured that to be brought into close contact between flaw detection wheel 13 and track, accurate to detect a flaw, institute
When stating the second 112 upward motion of support frame, the pressure of hold-down gear 14 is tightened up upwards, and tightening force drives the 3rd support frame 121
Left end is moved upwards, and now, the right-hand member control support body of the 3rd support frame 121 makes flaw detection wheel 13 de-orbit.
Further, the hold-down gear 14 is air bag, or is spring.
Described hold-down gear 14 is needed with certain elastic compression power, to enter between pull bar 114 and support block 113
When row release or engaging, the pressure between the first support frame 111 and the second support frame 112 is discharged or compressed；The pressure
Tight device 14 can select columned air bag, it is also possible to selection diameter than larger spring, make full use of air bag pressure or
The elastic force of person's spring.
Further, flexible member 15, the elasticity are connected between the support frame 121 of second support frame 112 and the 3rd
Element 15 carries out horizontal compression to supporting arrangement 12, so that flaw detection wheel 13 orbits.
The flexible member 15 increases the tightening force between the second support frame 112 and the 3rd support frame 121, described second
When support frame 112 is moved right, the left end of the 3rd support frame 121 is driven to move right, the pulling force of flexible member 15 reaches maximum,
Now, the right-hand member of the 3rd support frame 121 moves right flaw detection wheel 13, flaw detection 13 transverse fit tracks of wheel, second support
When frame 112 is to left movement, the pulling force of flexible member 15 is tightened up, and drives the left end of the 3rd support frame 121 to left movement, now, the
The right-hand member of three support frames 121 makes flaw detection wheel 13 laterally de-orbit.
Further, the flexible member 15 is pneumatic spring.
The speed of service of the pneumatic spring is relatively slow, can be good at tightening up pulling force, and dynamic force change less, compares
It is easily controlled.
Further, the other end of the 3rd support frame 121 is also connected with roller 16, and the roller 16 is to support wheel 122
Carried out with the side of flaw detection wheel 13 spacing.
The other end bottom connection roller frame of the 3rd support frame 121, the roller 16 is connected in roller frame, described
When support wheel 122 runs, roller 16 can be made to be fitted in the inner side of track, prevent support wheel 122 and flaw detection wheel 13 from derailing occur
Phenomenon, make support wheel 122 and flaw detection wheel 13 safe operations in orbit, more stablize.
Further, the other end of the support block 113 is provided with the breach for accommodating pull bar 114, so that pull bar 114 is along scarce
Mouth engaging departs from support block 113.
The other end of the support block 113 is provided with the breach of arc, and the upper end of the pull bar 114 can be fastened on breach
It is interior, it is also possible to depart from breach.
Further, the inner side of the support block 113 is formed with screw thread.
The medial surface of the breach is formed with screw thread, increases the friction between the upper end of pull bar 114 and the breach of support block 113
Power, prevents the upper end of pull bar 114 from being slid from indentation, there.
Further, described track defectoscope is two, and two track defectoscopes are detachably connected on control respectively
The both sides of device processed.
As shown in figure 4, two track defectoscopes are connected to the both sides of controller, using the side being detachably connected
The side of formula, i.e. defectoscope sets the first mounting bracket, and the support body side of controller sets the second mounting bracket, first mounting bracket
Slot is provided with the second mounting bracket, can quickly be connected, when using, two defectoscopes to the both sides of track respectively while visit
Wound, saves manpower, improves operating efficiency.
A kind of track defectoscope that the present invention is provided, the second support frame of the lifting apparatus enters to one end of support meanss
Row pressing is lifted, and the flaw detection wheel of the support meanss other end is lifted or fitted with track, so that it is guaranteed that flaw detection wheel exists
During work, contacted with track laminating all the time, more accurately detected a flaw；The upper end of the pull bar is connected with the first support frame, the drawing
