Description
Technical field
The present invention relates to a kind of retaining mechanism, more particularly, to the locking applied on a kind of rail vehicle gauge-changeable bogie
Mechanism, locked for the axle box device of slipping mechanism and bogie before and after becoming rail.
Background technology
Because countries in the world use different gauge standards, such as the railway of China is standard gauge, and gauge is
1435mm, Russian and most of Eastern Europe, the railway of country of Central Asia are broad gauge, gauge 1520mm.Also some countries
Gauge standard is the mm of narrow gauge 1000.During transnational through transport is carried out, domestic passenger traffic, freight transportation railway vehicle are by standard
, can not be directly by the way that need to stop the bogie changed and adapt to different gauge requirements when gauge lines are run to width, narrow gauge.
Gauge-changeable bogie is a kind of unconventional bogie, and its main distinction with conventional bogie is to take turns to knot
Structure, it is to realize the key of gauge changing function to take turns to structure design, and gauge-changeable bogie wheel pair is with conventional steering framing wheel to structure
Compared to, it is necessary to set up a set of locking device for gauge change, the device is that gauge-changeable bogie realizes that distance between backs of wheel flanges is adjusted
The critical component of whole and fixed distance between backs of wheel flanges, its act on be realize the unblock before wheelslip and it is operating be locked,
It is to directly affect the critical component that can smoothly realize distance between backs of wheel flanges change and ensure train operating safety.
With regard to retaining mechanism itself, it must assure that enough automaticitys, flexibility, accuracy and reliability, wheel
To inner side away from transition activities be that train is automatically performed, correspondingly, the unblock of retaining mechanism and lock by gauge changing facility
Tight action, which should also be, to be automatically performed；Become rail process typically with no more than 15km/h（Usual 7km/h）Speed pass through it is shorter
Become rail facility, realize and become rail, the time of whole change rail process is very short, therefore the unblock of retaining mechanism and locking action must be flexible
Quickly；The accuracy of locking is must assure that during vehicle normal operation, it is impossible to because the vibration of vehicle or other reasons make locking
Wheel release and produce it is traversing so that occur security incident, ensure retaining mechanism accuracy, make sure that wheel a certain
Suitable gauge position is locked, and otherwise, does not reach the purpose of gauge changing not only, it is also possible to security incident occurs.So research
The retaining mechanism that exploitation adapts to gauge-changeable bogie is the most important thing of gauge-changeable bogie technical research and exploitation.
The content of the invention
Fixed to solve conventional bogie distance between backs of wheel flanges, the problem of gauge changing translation function can not be realized, reduce across
Human and material resources cost increase caused by changing bogie during state's through transport, improves efficiency of operation, and the present invention provides a kind of locking dress
Put, realize unblock and locking effect of the gauge-changeable bogie to wheel during distance between backs of wheel flanges adjustment, ensure wheel after unblock
To inner side away from can freedom and flexibility adjustment, ensure after locking train retaining rail away from track on safe operation.
To achieve the above object, the present invention provides a kind of retaining mechanism for EMU gauge-changeable bogie, its
It is characterised by：Including check lock lever, working arm, node, actuating arm, connecting rod, spring, lower block and upper stopper, in the middle part of working arm and
Actuating arm is connected by connecting rod, and working arm one end is connected with pivoted arm hoop, and the working arm other end is connected with check lock lever, and spring is arranged on
On check lock lever, locking is realized in check lock lever upper end insertion axle box and the locking keyway of axle box swivel arm beam and pivoted arm hoop.
Described working arm connection pivoted arm hoop one end is provided with through hole, by setting node to connect pivoted arm hoop in through hole.
Described locking bar upper end is round key, round key insertion axle box and the locking keyway of axle box swivel arm beam and pivoted arm hoop
It is interior to realize locking.
Upper stopper is provided with above described spring, lower block is arranged below.
The locking keyway that the present invention is placed on axle box and axle box swivel arm beam and pivoted arm hoop by the round key on check lock lever,
The slide device being entirely fixedly connected with axle box is locked；When vehicle is by ground rail changing device, one end of retaining mechanism
Insert in the guide groove in the rail changing device of ground, and progressively forced down, principle is conjugated by connecting rod, check lock lever is elevated, and is locked
The round key of bar upper end departs from axle box, and axle box unlocks with axle box swivel arm beam and pivoted arm hoop, and slide device can realize free skating
Dynamic, the slide device after unblock is slided into up to new gauge position, when distance between backs of wheel flanges has adjusted under the effect of guided way pressure
Bi Hou, ground rail changing device control retaining mechanism, makes round key be embedded in axle box and axle box swivel arm beam and the lock of pivoted arm hoop again
In tight keyway, slide device, fixed distance between backs of wheel flanges are locked.Realize that gauge-changeable bogie is right during distance between backs of wheel flanges adjustment
Unblock and the locking effect of wheel.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structure decomposition figure of the present invention；
Fig. 3 is principle of the invention figure.
Embodiment
Reference picture 1, Fig. 2, retaining mechanism is by check lock lever 1, working arm 2, node 3, actuating arm 4, connecting rod 5, spring 6, lower block
