Description
Technical field
The present invention relates to rail vehicle wheel carrying out flaw detection technical field, more particularly to a kind of gantry type non-pulling wheel wheel
Defectoscope.
Background technology
Rail vehicle wheel is in operation and is subject to big alternate stress for a long time, may crack, cause safety inside it
Hidden danger, periodically should carry out ultrasonic examination to wheel to this.Recent domestic develops a kind of non-pulling wheel ultrasonic examination
Equipment, removes without by wheel, but is detected a flaw in the state of wheel is normally contained on vehicle.This defect-detecting equipment
Primitive form be: vehicle is parked on the vehicle rail of special hanger rail bridge, in the trench below track bridge lay one
The defectoscope track parallel with vehicle rail, flaw detection machine trolley moves on this track, can be parked in each wheel of vehicle successively
Lower section, then, the top wheel carrier of defectoscope rises, and wheel jack-up is departed from rail, and turns a wheel, then vertical on the wheel carrier of top
Guide rail rises further, enables the tread flaw detection mechanical hand on vertical guide rail to cling to Ultrasound Probe Device and is visited on wheel
Wound.
Because the lifting of top wheel carrier and vertical guide rail when existing equipment is detected a flaw is that (vertical guide rail is arranged on the wheel carrier of top serial kinematic
Side, top wheel carrier is indulged guide rail when rising and is risen therewith), the height correlation of the height of vertical guide rail and top wheel carrier, the lowest order of vertical guide rail
Put also in top wheel carrier adjacent upper part.In the narrow space position of wheel bottom, the higher tread defectoscope in position on vertical guide rail
It is necessary to wheel jack-up is exceeded the relatively rise of safety standard from could not collide with underbody parts, even if so during tool hands movement
Still cannot use under some vehicles.In addition, tread is detected a flaw the position of mechanical hand high so that by probe holder by the one of wheel
Side shifting, to opposite side, is realized in the flaw detection of wheel either side, mechanical hand must carry out the motion of complexity, and complex operation is time-consuming, effect
Rate is relatively low.These major defects in actual motion, be not suitable with high-speed railway run that rhythm is fast, the situation more than vehicle, need to develop
A kind of novel device of high efficiency non-pulling wheel flaw detection.
The drawbacks of lifting for solving top wheel carrier and vertical guide rail is serial kinematic, my company have developed a kind of rail vehicle not
Fall to taking turns ultrasound wave detecting flaw of wheel machine (referring to Chinese patent literature cn203148902u), it is mainly characterized by along described vehicle rail
Fixed support above the transportable chassis in road direction, is the vertical guide rail parallel with described stock rail direction in the middle part of support,
Tread probe mechanical hand is connected with vertical slide with its mechanical hand vertical guide rail frame it is possible to move along vertical guide rail；In support
On vertical guide rail both sides be respectively mounted two sets of lifting devices, fixed on support support the upper cross rail of cross rail to prop up
Frame, described upper cross rail pair is vertical with the direction of described stock rail, and wheel rim probe mechanism is connected on cross rail.This flaw detection
Though machine can solve the drawbacks of push up wheel carrier with vertical guide rail serial kinematic, due to the support beam of the defectoscope both sides in this patent documentation
Hook and top wheel carrier are separate, and are located at the both sides of longitudinal rail, and when top wheel carrier is by wheel jack-up, support beam hook bears top
Rise wheel power when, only bottom is fixed on pedestal, and the intensity of the higher support beam hook of separate and center of gravity is relatively
Weak, when carrying the larger pressure at the wheel, it is easily deformed or even fractures, thus lead to hook claw departing from vehicle rail
Accident occur, therefore its job stability is poor, and has certain potential safety hazard.Additionally, the flaw detection in this patent documentation
Machine when there is error in trolley track and vehicle location of rail and direction it is impossible to enough automatic capturings, thus constituting to flaw detection operation
Impact.

Being detected a flaw in two wheel tread positions, and then improves tread flaw detection efficiency.
In the present embodiment, described wheel rim failure detector is arranged between two described rollers 18 on the wheel carrier 7 of described top, institute
State the wheel rim flaw detection mechanical hand 9 that wheel rim failure detector includes being fixed on the wheel carrier 7 of described top, and be arranged on described wheel rim defectoscope
The wheel rim probe holder 8 of tool handss 9 upper end, due to being equipped with wheel rim probe 8 on door frame 6 each described, when two door frames 6 are to two
When the lapping ends of lateral movement extremely hook pawl 15 are to vehicle rail, wheel rim probe holder 8 is located exactly at the underface of rim for automobile wheel, car
After wheel jack-up, the probe on two wheel rim probe holders 8 can be visited to the wheel rim position of two wheels on same axis simultaneously
Wound, and then improve the efficiency of wheel rim flaw detection.
The operation principle of the gantry type non-pulling wheel detecting flaw of wheel machine of the present invention is:
First vehicle to be measured is parked on hanger rail bridge rail, is bogie under the compartment of rail vehicle, general one
Two axletrees are had on bogie, each axletree two ends wheel-mounted, the excircle of wheel is referred to as tread, and tread is connect with rail surface
Touch, inside tread, also have a circle external diameter to be more than the wheel rim of tread external diameter, inside the face being connected with tread outside wheel rim and rail
Contact, play the guiding role, wheel rim medial surface is referred to as wheel rim.
During flaw detection work, chassis 1 moves to below an axletree of vehicle in melt pit, and two door frames 6 are first transversely
Guide rail 13 also extends therewith to vehicle rail one side shifting, the at this moment locking cylinder between two door frame 6 upper ends, now controlled section
Only valve 17 is opened, and the fluid in locking cylinder two chamber is exchanged and supplemented by oil feeding reservoir 16；Reach car when hooking pawl 15 front end
When above wheel rail surface, the controllable stop valve 17 of locking cylinder is closed, and the two door frame 6 upper end oil cylinder that is locked is integrally fixed,
So latter two top wheel carrier 7 rises along the upright guide rails 610 on respective door frame 6, when the roller 18 on the wheel carrier 7 of top pushes up wheel,
The counter-force of wheel compresses preloading spring 101 by guide rail bracket 7, and top wheeling support 60, hook pawl 15 also decrease, and hook pawl 15 front end and take
On wheel rail surface, after wheel rail is played a supporting role to hook pawl 15, top wheel carrier 7 continues to rise, and wheel jack-up is taken off
From rail.Because two door frame 6 upper ends oil cylinder that has been locked is integrally fixed, its intensity just can undertake the pressure of jack-up wheel
Power, the power of jack-up wheel is delivered on vehicle rail eventually through hooking pawl 15.Rear tread pattern defectoscope tool handss 3 along tread detect a flaw
Longitudinal rail 12 on bearing 2 is mobile, by the gap between two door frames 6, moves to the side that tested vechicle wheel is selected, by two
Individual tread probe holder 4 clings on the tread of two wheels, is simultaneously attached to the wheel rim flaw detection mechanical hand 9 on two top wheel carriers 7
Also two wheel rim probe holders 8 are clinged on the wheel rim of two wheels, drive vehicle wheel rotation it is possible to same with rear roller 18
Two wheels on root axletree carry out detecting a flaw simultaneously.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.Right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Change among still in the protection domain of the invention.
