861 are located at the opposite other side of the lug 863 for being inserted into the inner concave arc surface 91.In gauge changing, it is located at outer sleeve
The locking pins 86 of both sides passes through the unlock inclined-plane 100 simultaneously, and shank 861 is gradually raised by upward active force, from it is lower to
Upper disengaging groove 832 completes unlock, and lug 863 is detached from groove 832 from bottom to top first, is moved to the top of groove 832, this
When the lower section of lug 863 notch 864 it is opposite with 831 position of boss between two grooves 832, wheel 81 is led by gauge changing at this time
Apply leftward or rightward external force to rail 30, outer sleeve follows wheel 81 to move together, and boss 831 is caught in notch 864 and edge
Notch 864 moves, and the lower end of lug 863 is supported on the table top of boss 831, until it is moved to the position of another groove 832,
The one section locking inclined-plane 110 that is equipped with diagonally downward opposite with the locking section 60 of the supporting rail 10, when positioned at outer sleeve two
When the locking pin 86 of side passes through the locking inclined-plane 110 simultaneously, work of the shank 861 in 85 downward force of its own gravity and resetting spring
With lower edge, the locking inclined-plane 110 diagonally downward gradually moves down, until lug 863 is inserted into the groove 832, completes locking, becomes
Gauge is completed.Further, it steadily, is swimmingly completed to ensure to unlock and lock, the unlock inclined-plane 100, locking inclined-plane
110 is consistent with the angle of inclination of the guiding surface 865.
Wherein, the inner face of the axle box 90 is equipped with the through-hole for outer sleeve sliding, the circumferential shape of the through-hole
At interior backstop 92, the outer end face of the axle box 90 is equipped with outer end cap 93, the downside axial direction both ends difference outside the axle box 90
Equipped with outer backstop 94；One end of first guide rail 20 towards the gauge changing guided way 30 is set as the first slope diagonally downward
Face, which forms track, reduces section 21, what one end of second guide rail 40 towards the gauge changing guided way 30 was set as tilting upward
Second slope surface forms track and is lifted section 41.The present invention concrete operating principle be：When gauge-changeable wheelsets 80 are reduced by the track
When section 21, wheel 81 unloads, and is played a supportive role by axle box 90, at this point, the outer backstop 94 at the axial both ends in its downside sets up separately
In the both sides of the supporting rail 10, whole driven by supporting rail 10 of bogie moves forward, until gauge changing is completed, gauge changing wheel
Become wheel 81 again after the track is lifted section 41 to 80 to carry.Due to being respectively provided with push-tight in unlock section 50 and locking section 60
Positioning device 70, when wheel is to close to unlock section 50, push-tight positioning device 70 is from external side compression wheel 81 is taken turns, at this point, wheel
81 drive outer sleeves inwardly slightly move so that outer sleeve and the interior backstop 92 of 90 inner end of axle box recline (as shown in figure 11)；
And 10 outside of supporting rail and the outer backstop 94 of 90 downside axial outer end of axle box recline, at this point, 863 both sides of lug of locking pin 86
With groove 832 without active force, that is, no coupling mechanism force, it is ready for the change rail of next step；Realize supporting rail 10, axle box
90, outer sleeve, locking pin 86 are accurately positioned, and reduce the cross force of axle box 90 and outer sleeve to locking pin 86, and then subtract
Vertical frictional resistance when small locking pin 86 acts, the unlocking motion for being conducive to locking pin 86 are smoothed out.
When wheel is to close to locking section 60, push-tight positioning device 70 is from internal side compression wheel 81 is taken turns, at this point, 81 band of wheel
Dynamic outer sleeve slightly moves outward so that the outer end cap 93 of outer sleeve and axle box 90 reclines (as shown in figure 12)；And it props up at this time
The outer backstop 94 of support rail 10 inside and 90 downside axial inner ends of axle box reclines, at this point, 863 both sides of lug of locking pin 86 with it is recessed
Slot 832 realizes supporting rail 10, axle box 90, outer sleeve, locking pin 86 and is accurately positioned, reduce axle box without active force
Body 90 and outer sleeve reduce vertical frictional resistance when locking pin 86 acts to the cross force of locking pin 86, are conducive to
The locking action of locking pin 86 is smoothed out.
Certainly, when gauge-changeable wheelsets 80 are run from the second guide rail 40 to the direction of the first guide rail 20, original locking section
60 become unlocking section 50, and original unlock section 50 becomes locking section 60, and becomes to become rail from broad gauge to standard gauge, and whole process is
The inverse process of the above process.
Wherein, the push-tight positioning device 70 includes spaced multiple being stretched along the length direction of the supporting rail 10
Contracting push rod 71, the length direction for being axially perpendicular to the supporting rail 10 of the scalable push rod 71.Further, the push-tight
Positioning device 70 further includes fixed part 72, and the fixed part 72 is fixed on ground, and the scalable push rod 71 can be along the fixation
The axial direction in portion 72 moves back and forth, and the end of the scalable push rod 71 is equipped with resilient sleeve, to reduce scalable push rod 71 and wheel
Frictional force between 81.Preferably, the push-tight positioning device 70 is hydraulic pressure or pneumatic actuator, to facilitate according to control instruction
It is automatic to apply thrust.
In order to steadily apply lateral thrust to the wheel 81 before and after entering unlock section 50, and locked to entering
Wheel 81 before and after section 60 steadily applies lateral thrust, has extended outwardly arrangement along the both ends of the unlock section 50
State push-tight positioning device 70；Extend outwardly along the both ends of the locking section 60 and is placed with the push-tight positioning device 70.
Scalable push rod 71 directly abuts to wheel 81 for convenience, is located at a pair branch in 50 outside of unlock section
Support rail 10 is respectively equipped with the location hole passed through for the scalable push rod 71 at the position opposite with the push-tight positioning device 70.
As can be seen from the above embodiments, the present invention is by setting in unlock section 50 and its neighbouring, locking section 60 and its nearby
Push-tight positioning device 70 is set, the positioning accuracy of 80 retaining mechanism of gauge-changeable wheelsets is improved, is conducive to unlock/lock of locking pin 86
Tight action is smoothed out, and by the way that unlock emergency braking section 51 is arranged after unlocking section 50, and vehicle can be in the urgent system of unlock
Dynamic section 51 is braked, and the wheel not unlocked is avoided to become rail section to entering, and vehicle and ground is caused to become the damage of rail facility and cause
Safety accident；The setting locking emergency braking section 61 after locking section 60, vehicle can be in locking emergency braking sections 61 simultaneously
Braking avoids the vehicle that locking fails from causing safety accident.
In addition, the present invention close to unlock section 50 latter end be arranged unlocked state monitoring device, for unlock whether at
Work(is monitored, and locking state monitoring device is arranged in the latter end close to locking section 60, for whether successfully being supervised to locking
It surveys, to contribute to whether driver's accurate judgement unlocks successfully or lock successfully, whether to carry out corresponding urgent system in next step
It is dynamic that accurate foundation is provided, it avoids causing safety accident, safety guarantee is provided.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
