3, traction link device: in the time of gallery locomotive haulage, adopt traction link hard connecting mode, can realize the series connection transport successively of many cars front and back, improve conveying efficiency.Linkage can ensure that the flat truck before and after when brake can not bump against, and traction link device adopts doubly-linked joint style simultaneously, can realize universal rotational, ensures planar curve path and normal driving on vertical bend, and its safety factor reaches more than 6 times.
Flat truck main technical details is as follows:
A, maximum gross: 40t;
B, gauge: 600mm;
C, wheel base: 1500mm;
D, draw high 267mm;
E, flat truck oad (length × wide × height): 3300mm × 1680mm × 332mm;
F, bend minimum profile curvature radius are 12m;
G, the maximum ramp angle of bicycle are 20 °;
H, bicycle tractive force limit are 156.8KN;
I, straight way maximum speed are no more than 2m/s, and bend is no more than 1m/s.
Advantage is as follows:
1, meet under 30～40 tons of loading strengths and belt heading conditional request prerequisite, realized the rail transport of whole of heavy hydraulic support under coal mine or load center.
2, simple in structure, carrying is heavy, good stability, and low to tunnel conditional request, and comformability is good.
3, easy to manufacture, sturdy and durable, running resistance is little, easy to maintenance etc.
The utility model is reasonable in design, simple in structure, met 30～40 tons of loading strengths and short belt heading conditional request, has realized the rail transport of whole of heavy hydraulic support under coal mine or load center.
