After guarantor lead screw extension end is connect with connecting hole 82, electric cylinder 11 and mobile disk 8 do not have relative displacement, it is ensured that the mobile essence of wheel 4
Degree.
When gauge narrows from the width, electric cylinder 11 pushes mobile disk 8 mobile to the direction far from axle box 7,8 band of mobile disk
Motor car wheel 4 is mobile simultaneously；Realize that broad gage narrows gauge.
When gauge is by narrow broaden, electric cylinder 11 pulls mobile disk 8 mobile to the direction of axle box 7, and mobile disk 8 is with motor-car
Wheel 4 is mobile simultaneously；Realize that arrow gauge broadens gauge.
In a specific embodiment of the invention, as shown in fig. 7, the disk body setting is in class diamond shape, institute to reduce weight
The apex angle for stating class diamond shape is disposed as the arc connecting with adjacent side transition, and a pair of connecting hole 82 is respectively arranged on the disk
Opposite a pair of of vertex on body；Another pair vertex can will be set as due to no setting is required connecting hole 82 at the vertical angles

The installation space of Moving plate 8.
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 uses active gauge changing structure, is controlled by the on-off of tractive magnet
Dynamic iron core is stretched out or is shunk, and realizes wheel locking and unlock, can be directly realized by locking and unlock without external equipment；Make
Obtaining ground change rail facility becomes relatively easy, and cost reduces, and becomes rail signal and is exported by vehicle control system, improves change rail and acts
Reliability and become rail efficiency.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
