Power i.e. driving mechanism output power required for the scratch of axle 5, reduction wheel 4 are mobile when to avoid wheel 4 mobile,
Unload wheel 4 by the way of supporting at axle box using supporting rail here.Therefore a set of support need to be installed in ground rail two sides
Rail.
Become path section, supporting rail occurred before this, and narrow gauge section rail and supporting rail coexist one section.Then, rail moves back
Out, only supporting rail supports, and completes the variation of gauge in this section.Then, broad gauge line section rail occurs, and coexists with supporting rail
One section.Finally, supporting rail is gradually reduced, exits, into broad guage line.
Supporting rail supporting surface is identical away from elevation of water as axle box bottom away from elevation of water, and both ends height is lower,
Carry out load/unload process slowly, to avoid impact is generated.There is a side block structure in its outside, prevent train transverse movement and
Skid off supporting surface.
Gauge changing process is divided into 5 unloading of wheel 4, unlock, traversing, locking, load processes, here with from standard gauge
For the gauge changing of 1435mm to broad gauge 1520mm, to illustrate the active gauge changing process for becoming rail scheme.
The first step, wheel 4 unload: train runs to change path section speed per hour degree from 1435mm gauge and is reduced to 15m/s, so
Afterwards as train advances, supporting rail is gradually increasing, after supporting rail contacts with axle box 7 and runs a small distance, standard gauge steel
Rail exits, and wheel 4 unloads completely.
Second step, wheel 4 unlock: the equipment being mounted in ground supports rail issues 4 unloader signal of wheel.Control mechanism is given
Retaining mechanism 3 is powered, and is successively powered inside tractive magnet 32 by sucker coil 34, hauling-eye 32-1, dynamic iron core 32-2 solution
It locks and is shunk with 4 locking pin 33 of motor car wheel, wheel 4 unlocks.When tractive magnet 32 checks dynamic iron core 32-2 in retraction position,
The signal that wheel 4 unlocks is issued, control mechanism powers off sucker coil 34, hauling-eye 32-1 successively, for a long time to prevent coil
It is powered and burns.At this point, dynamic iron core 32-2, which is stuck in wheel 4, by lock pin 35 solves lock-bit.
Gauge changing: third step after control mechanism receives the signal of the unlock of wheel 4, makes sucker coil 34, draught line
While circle 32-1 is successively powered off, planetary roller screw electric cylinder energization (this energization direction of planetary roller screw electric cylinder is given
With last time on the contrary, i.e. last time logical reversed electric this leads to positive electricity).It is new that the dynamic mobile disk 8 of 11 push/pull of electric cylinder reaches wheel 4
Gauge position.
4th step, wheel 4 are locked: electric cylinder 11 issues gauge variation completion signal after reaching travel position, then draws
The sucker coil 34 of electromagnet 32 is powered, dynamic iron core 32-2 unlock, and band 4 locking pin 33 of motor car wheel under the effect of spring-return power
It stretches out.When detection device detects that dynamic iron core 32-2 is in stretching position, issuing wheel 4 and lock signal, sucker coil 34 powers off,
Dynamic iron core 32-2 and 4 locking pin 33 of wheel lock in 4 locking position of wheel, are prevented it from moving under the action of the centrifugal force by lock pin 35.
5th step, wheel 4 load: 1520mm gauge rail occurs, and supporting rail is gradually reduced, and wheel 4 reloads；Entirely
Becoming rail process terminates.
As can be seen from the above embodiments, the present invention realizes the traversing of wheel by transversal driving mechanism, so that wheel is horizontal
Mobile work is more steady, can reduce the abrasion of wheel between centers, improve the reliability of gauge changing.Meanwhile using active gauge changing
Structure is stretched out or is shunk by the on-off control dynamic iron core of tractive magnet, realized wheel locking and unlock, set without outside
It is standby to be directly realized by locking and unlock；So that ground becomes rail facility and becomes relatively easy, become rail signal by vehicle control system
Output improves the reliability for becoming rail movement and becomes rail efficiency.
