Description
Technical field
The present invention relates to rail vehicle wheel carrying out flaw detection technical field, particularly relate to a kind of gantry type and do not fall to taking turns detecting flaw of wheel machine.
Background technology
Rail vehicle wheel is in operation and is subject to for a long time large alterante stress, and its inside may crack, and causes potential safety hazard, to this, should regularly to wheel, carry out UT (Ultrasonic Testing).Recent domestic has been developed a kind of equipment that does not fall to taking turns UT (Ultrasonic Testing), wheel need not be removed, but normally be contained under the state on vehicle and detect a flaw at wheel.The citation form of this defect-detecting equipment is: vehicle is parked on the vehicle rail of special-purpose hanger rail bridge, in trench below track bridge, lay a defectoscope track parallel with vehicle rail, defectoscope chassis moves on this track, can be parked in successively each wheel below of vehicle, then, the top wheel carrier of defectoscope rises, wheel jack-up is departed to rail, and turn a wheel, then the vertical guide rail on the wheel carrier of top further rises, and makes the tread flaw detection mechanical arm on vertical guide rail Ultrasound Probe Device can be clinged on wheel and detect a flaw.
While detecting a flaw due to existing equipment, the lifting of top wheel carrier and vertical guide rail is that (vertical guide rail is arranged on wheel carrier top, top in serial campaign, when top wheel carrier rises, vertical guide rail rises thereupon), the vertical height of guide rail and the height correlation of top wheel carrier, the extreme lower position of vertical guide rail is also near wheel carrier top, top.In narrow space position, wheel bottom, on vertical guide rail during the higher tread flaw detection robot movement in position, wheel jack-up must be exceeded safety standard compared with rise from, could be and parts collision at the bottom of car, even like this under some vehicle or cannot use.In addition, the position of tread flaw detection mechanical arm is high, makes probe holder to be moved by side to opposite side by one of wheel, realizes in the flaw detection of wheel either side, and mechanical arm must carry out complicated motion, and complex operation is time-consuming, and efficiency is lower.These major defects in actual motion, are not suitable with the situation that high-speed railway operation rhythm is fast, vehicle is many, need to develop the novel device that a kind of high-level efficiency does not fall to taking turns flaw detection.
For solving the lifting of top wheel carrier and vertical guide rail, it is the drawback of serial campaign, my company has researched and developed a kind of rail vehicle and has not fallen to taking turns ultrasound wave detecting flaw of wheel machine (referring to Chinese patent literature CN203148902U), its principal character is to be fixed wtih support above the transportable chassis of described stock rail direction, support middle part is the vertical guide rail parallel with described stock rail direction, tread probe mechanical arm is slidably connected with its mechanical arm vertical guide rail frame and vertical guide rail, and can move along vertical guide rail; Vertical guide rail both sides on support are installed with respectively two cover lifting devices, are fixed wtih the top rail rail brackets of cross rail in support on support, and described upper cross rail is pair vertical with the direction of described stock rail, and wheel rim probe mechanism is connected on cross rail.Though this defectoscope can solve the drawback of top wheel carrier and vertical guide rail serial campaign, but because brace summer hook and the top wheel carrier of the defectoscope both sides in this patent documentation are separate, and be positioned at the both sides of longitudinal rail, when top wheel carrier is by wheel jack-up, when brace summer hook bears the power of jack-up wheel, only that bottom is fixed on pedestal, the intensity of the separate and brace summer hook that center of gravity is higher a little less than, in carrying during from the larger pressure at wheel place, easily distortion even fractures, thereby cause hooking the accident generation that claw departs from vehicle rail, therefore its job stability is poor, and there is certain potential safety hazard.In addition, the defectoscope in this patent documentation, can not automatic capturing when trolley track and vehicle location of rail and direction generation error, thereby flaw detection operation is formed to impact.

The principle of work that gantry type of the present invention does not fall to taking turns detecting flaw of wheel machine is:
First vehicle to be measured is parked on hanger rail bridge rail, under the compartment of rail vehicle, it is bogie, on a general bogie, there are two axletrees, each axletree two ends wheel-mounted, the excircle of wheel is called tread, and tread contacts with rail surface, tread inner side also has a circle external diameter to be greater than the wheel rim of tread external diameter, side contacts in the face that wheel rim outside is connected with tread and rail, play the guiding role, and wheel rim medial surface is called wheel rim.
During flaw detection work, chassis 1 moves to below an axletree of vehicle in melt pit, two door frames 6 are first along cross slide way 13 to vehicle rail one side shifting, at this moment the locking cylinder between two door frame 6 upper ends also extends thereupon, now controllable stop valve 17 is opened, and the fluid in locking cylinder two chambeies is exchanged and supplemented by oil feeding reservoir 16; When hooking pawl 15 front ends arrival wheel rail surface top, the controllable stop valve 17 of locking cylinder is closed, the two door frame 6 upper ends oil cylinder that is locked is fixed into one, so latter two top wheel carrier 7 rises along the upright guide rails 610 on door frame 6 separately, when wheel is arrived on roller 18 tops on top wheel carrier 7, the counter-force of wheel is by guide rail bracket 7 compression preloading springs 101, top wheeling support 60, hook pawl 15 also decrease, hooking pawl 15 front ends rides 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 departed to rail.Because two door frame 6 upper ends oil cylinder that has been locked is fixed into one, its intensity just can be born the pressure of jack-up wheel, and the power of jack-up wheel is finally delivered on vehicle rail by hooking pawl 15.The mechanical arm 3 of tread flaw detection afterwards moves along the longitudinal rail 12 on tread flaw detection bearing 2, by the gap between two door frames 6, move to the selected side of tested vechicle wheel, two tread probe holders 4 are clinged on the tread of two wheels, be arranged on two wheel rim flaw detection mechanical arms 9 on top wheel carrier 7 also clings to two wheel rim probe holders 8 on the wheel rim of two wheels simultaneously, with rear roller 18, drive vehicle wheel rotation, just can detect a flaw to two wheels on same axletree simultaneously.
Obviously, above-described embodiment is only for example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being extended out thus or change are still among the protection domain in the invention.
