Kind is used for preventing gnawing rail device, beam-hanging traveling crane and its walking method of beam-hanging traveling crane.
Background technique
Currently, the Bridge Erector of large-tonnage is using more and more extensive, and have that span is big, lifting capacity weight, lifting altitude are high, work
The features such as rank is high, this design for allowing for beam-hanging traveling crane matched with its become particularly important.It is particularly due to manufacture and pacify
Fill error, overhead traveling crane traveling it is easy to appear gnawing rail phenomenon, it is regular gnaw rail for a long time not only can be to track, wheel, motor etc.
Relevant device causes very big damage, influences the safety and steady operation of equipment, serious or even also result in serious accident
Generation.
The method of rail is gnawed in addition to the essence in manufacture installation strict control wheel and track from configuration aspects solution at present
It is outside one's consideration, also has and much set about from the design of the wheel rim of wheel, scheme that there are mainly two types of: a sidecar wheel is without wheel rim, another side vehicle
Wheel is two-wheel edge；Two sidecar wheels are single-wheel edge.Two schemes can only mitigate the phenomenon that gnawing rail in a certain range, but cannot
It is enough to avoid gnawing rail completely.There are also the method for gnawing rail is addressed in terms of control, although this control means are in certain journey
It can be reduced the phenomenon that gnawing rail on degree, but that there are reliabilities is poor, maintenance difficulty is big, costly and stability is poor etc. lacks
Point.
