Schematic diagram；
Fig. 2 is a kind of safety device for preventing rail traffic vehicles derailed of the present invention shown in figure 1 at another
Structural schematic diagram in visual angle.
Specific implementation mode
The present invention is described in detail for each embodiment shown in below in conjunction with the accompanying drawings, but it should explanation, these
Embodiment is not limitation of the present invention, those of ordinary skill in the art according to function, method made by these embodiments,
Or the equivalent transformation in structure or replacement, all belong to the scope of protection of the present invention within.
It please join the one of Fig. 1 and a kind of safety device for preventing rail traffic vehicles derailed of the present invention illustrated in fig. 2
Kind specific implementation mode.In the present embodiment, a kind of safety device for preventing rail traffic vehicles derailed, is set to two
The centre position of track 6.Rail in the prior art can be used in track 6.The peace for being used to prevent rail traffic vehicles derailed
Full device, including：Two bogies 1, connecting plate 5 and the Auxiliary Track 3 of longitudinally asymmetric setting, wherein Auxiliary Track 3 fix peace
Being reliably connected for rigidity is realized in top loaded on sleeper 7, connecting plate 5 and the bottom in compartment 8.The bottom in compartment 8 passes through vehicle frame, bullet
The parts such as spring (not shown) are assembled with wheel 9.
