The specific embodiment
This specific embodiment provides a kind of mounting structure of chassis, and it can avoid the unstable problem that causes chassis to gnaw rail or derailing because of track radian.This specific embodiment also provides a kind of locomotive crane that comprises the assemble mechanism of above-mentioned chassis.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 2, Fig. 2 is chassis mounting structure schematic diagram in the utility model specific embodiment.
The mounting structure of a kind of chassis provided in the present embodiment, between adjacent two chassis 11 and equalizer bar 12, be provided with swing arm 13, one end of swing arm 13 is hinged with chassis 11 by the first vertical pivot 14, and the other end is hinged with equalizer bar 12 by the second vertical pivot 15.
It should be noted that, one end of above-mentioned swing arm 13 is hinged with chassis 11 by the first vertical pivot 14, the one end and the chassis 11 that mean swing arm 13 are hinged, and hinge vertically arranges, and so swing arm 13 can be take the first vertical pivot 14 and at horizontal surface, swung as centre of gration; In like manner, the other end of swing arm 13 is hinged with equalizer bar 12 by the second vertical pivot 15, also refers to that the second vertical pivot 15 vertically arranges.
So arrange, chassis 11 orbits, when crane track occurs when unstable, be that crane track radian is when change, the swing that two swing arms 13 can produce in horizontal surfaces around the first vertical pivot 14 and the second vertical pivot 15, and then the angle between two chassis 11 can automatically adjust to adapt to the variation of track radian.Therefore, the mounting structure of chassis 11 provided in the present embodiment, can avoid the unstable problem that causes chassis 11 to gnaw rail or derailing because of track radian.
