Description
Technical field
The utility model is related to a kind of retaining mechanisms, more particularly, to what is applied on a kind of rail vehicle gauge-changeable bogie
Retaining mechanism is locked for the axle box device of slipping mechanism and bogie before and after becoming rail.
Background technology
Since 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, country of Central Asia railway be broad gauge, gauge 1520mm.Also some countries
Gauge standard is 1000 mm of narrow gauge.During carrying out transnational through transport, domestic passenger traffic, freight transportation railway vehicle are by standard
When gauge lines are run to width, narrow gauge, can not directly it pass through, need to stop the bogie replaced and adapt to different gauge requirements.
Gauge-changeable bogie is a kind of unconventional bogie, and the main distinction of it and conventional bogie is to take turns to knot
Structure, wheel are the key that realize gauge changing function to structure design, and gauge-changeable bogie wheel pair is with conventional steering framing wheel to structure
It compares, needs to add a set of locking device for gauge variation, which is that gauge-changeable bogie realizes distance between backs of wheel flanges tune
The critical component of whole and fixed distance between backs of wheel flanges, effect be unlock before realizing wheelslip and it is running be locked,
It is to directly affect the critical component that can smoothly realize distance between backs of wheel flanges variation and ensure train operating safety.
Itself with regard to retaining mechanism, enough automaticitys, flexibility, accuracy and reliability be must assure that, taken turns
To inside away from transition activities be that train is automatically performed, correspondingly, the unlock of retaining mechanism and lock by gauge changing facility
Tight action, which should also be, to be automatically performed；Become rail process generally to be not more than 15km/h（Usual 7km/h）Speed pass through it is shorter
Become rail facility, realize and become rail, the entire time for becoming rail process is very short, therefore retaining mechanism unlock and locking action must be flexible
Quickly；It must assure that the accuracy of locking when vehicle normal operation, vibration or other reasons that cannot be because of vehicle make locking
Wheel loosen and generate it is traversing so that occur safety accident, ensure retaining mechanism accuracy, make sure that wheel a certain
It is locked suitable for gauge position, otherwise, the purpose of gauge changing is not only not achieved, it is also possible to safety accident occur.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.
Utility model content
Cannot achieve gauge changing conversion function to solve the problem of that conventional bogie distance between backs of wheel flanges is fixed, reduce across
Human and material resources cost increases caused by replacing bogie when state's through transport, improves efficiency of operation, and the utility model provides a kind of locking
Device is realized that gauge-changeable bogie acts on the unlock of wheel and locking during distance between backs of wheel flanges adjusts, is ensured after unlock
The adjustment of distance between backs of wheel flanges energy freedom and flexibility, ensure after locking train retaining rail away from track on safe operation.
To achieve the above object, the utility model provides a kind of locking machine for high-speed EMUs gauge-changeable bogie
Structure, it is characterised in that：Including check lock lever, working arm, node, actuating arm, connecting rod, spring, lower stopper and upper stopper, in working arm
Portion is connected with actuating arm by connecting rod, and working arm one end is connect with pivoted arm hoop, and the working arm other end is connected with check lock lever, spring peace
On check lock lever, check lock lever upper end, which is inserted into axle box and the locking keyway of axle box swivel arm beam and pivoted arm hoop, realizes locking.
Described working arm connection pivoted arm hoop one end is provided with through-hole, and pivoted arm hoop is connected by the way that node is arranged in through-hole.
The locking bar upper end is round key, and round key is inserted into the locking keyway of axle box and axle box swivel arm beam and pivoted arm hoop
Interior realization locking.
It is equipped with upper stopper above the spring, lower stopper is arranged below.
The utility model is placed in the locking on axle box and axle box swivel arm beam and pivoted arm hoop by the round key on check lock lever
Keyway, the slide device being entirely fixedly connected with axle box are locked；When vehicle is by ground rail changing device, retaining mechanism
One end is inserted into the guide groove in the rail changing device of ground, and is gradually forced down, and principle is conjugated by connecting rod, and check lock lever is elevated,
The round key of check lock lever upper end is detached from axle box, and axle box is unlocked with axle box swivel arm beam and pivoted arm hoop, and slide device can be realized certainly
By sliding, the slide device after unlock is under the effect of guided way pressure, and sliding reaches new gauge position, when distance between backs of wheel flanges tune
After whole, ground rail changing device controls retaining mechanism, and round key is made to be embedded in axle box and axle box swivel arm beam and pivoted arm hoop again
Locking keyway in, lock slide device, fixed distance between backs of wheel flanges.Realize that gauge-changeable bogie adjusts process in distance between backs of wheel flanges
In the unlock and locking of wheel are acted on.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural exploded view of the utility model；
Fig. 3 is the utility model principle figure.
Specific implementation mode
Referring to Fig.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
Block 7 and upper stopper 8 form.Working arm 2 and actuating arm 4 are connected by connecting rod 5, and 2 one end of working arm passes through node 3 and axle box swivel arm
