Abstract
The utility model relates to a floating shaft of the electric two-beam crane trolley, which comprises a floating shaft and a driven wheel group. The utility model is characterized in that two ends of the floating shaft are equipped with a driven wheel group respectively. The floating shaft is positioned on the base of the floating shaft, the pin of the floating shaft and two regulating shafts are fixed on the floating shaft by clamp spring respectively, and the base of the floating shaft is fixed on two sides of the side plate of the trolley. The utility model regulates voluntarily its position in the kidney slot to adjust two driven wheel groups, and make its force on the same plane, so as to assure the stable operation of trolley and prevent from slipping of trolley wheel. The utility model has the advantages of reasonable design, simple and convenient structure and low cost.
Description
Technical field
The utility model relates to a kind of electronic double girder crane dolly floating axle of guaranteeing that monkey is stable.
Background technology
At present, in the manufacturing process of electronic double girder crane dolly,, cause the trolley travelling instability because the accumulated error that forms in welding deformation and the processing causes four wheels stressed not at grade, tyre skidding, thus influence the process of engineering.
The utility model content
The purpose of this utility model provides a kind of automatic compensation two flower wheels that pass through, and makes four wheels at grade stressed, guarantees that trolley travelling is stable, prevents tyre skidding and reasonable in design, electronic double girder crane dolly floating axle simple in structure, with low cost.
The utility model comprises floating axle and driven wheels, it is characterized in that:
Driven wheels are equipped with at a, floating axle two ends respectively;
B, floating axle are loaded on the floating axle bearing, and float pivot pin and two adjusting shafts are fixed on the floating axle by jump ring respectively, and the floating axle bearing is fixed in dolly side plate both sides.
Floating axle places the floating axle middle part, and two adjusting shafts place the pivot pin both sides of floating, and are loaded in the kidney slot.Described driven wheels comprise flower wheel, capping, bearing, jump ring and spacing sleeve.
Electronic double girder crane dolly is in the middle of the process of operation, float pivot pin as a fulcrum between the two driven wheels, when the two-wheeled unbalance stress, adjusting shaft by the pivot pin both sides of floating, change its position in kidney slot voluntarily and adjust two driven wheels, it is got back on the same plane of constraint, thereby guarantee that trolley travelling is stable, prevent tyre skidding.
Effect of the present utility model:
1, the utility model is regulated its position in kidney slot voluntarily by adjusting shaft and is adjusted two driven wheels, makes it at grade stressed, thereby guarantees that trolley travelling is stable, prevents tyre skidding, thereby guarantees works progress.
2, the utility model is reasonable in design, and features simple structure is with low cost.
