Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
See Fig. 1, it is the structural representation of a kind of large-scale heavy rail heat-treatment lines Quick transport device embodiment of the present invention, comprise inlet roller way 1, determine beam 2, dynamic beam group 3, translating trolleys 4, trolley track 5 and outlet roller-way 6, inlet roller way 1 and outlet roller-way 6 lay respectively at the two ends end to end of dynamic beam group 3, between adjacent dynamic beam group, dynamic beam group 3 comprises mutual vertically disposed dynamic crossbeam 7 and dynamic longeron 8, length direction along dynamic crossbeam 7 is minimum arranges two to dynamic longeron 8, the top of often pair of dynamic longeron 8 is provided with a trolley track 5, translating trolleys 4 rolls along trolley track 5 by the wheel 9 of himself, determine beam 2 to lay along the below of trolley track 5, the below of determining beam 2 is provided with determines beam support 24, be provided with entrance sprocket wheel 10 in the inlet roller way side of determining beam 2, the outlet roller-way side of determining beam 2 is provided with outlet sprocket wheel 11, and the two ends of chain 12 are walked around entrance sprocket wheel 10 and are connected to rear side and the front side of translating trolleys 4 after exporting sprocket wheel 11 separately, the below of dynamic crossbeam 7 is provided with dynamic beam hoisting appliance 13.
