Described flexible casing 2 comprises telescopic rail 8 and telescopic boom 9, and telescopic boom 9 one ends insert telescopic rail 8, and telescopic boom 9 other ends are connected with rear support leg casing 1.
Described telescopic rail 8 is square or circular telescopic rail.
The radial section of described telescopic rail 8 and telescopic boom 9 is shaped as octagon, and simple in structure, area of contact is big, and stability strengthens greatly.
Described telescopic boom 9 is the corrosion-resistant steel telescopic boom, and is convenient and practical, withstanding corrosion.
Described rear support leg casing 1 is welded as a whole with telescopic boom 9, and the structural strength height is simplified procedure of processing.
Described hydraulically extensible oil cylinder 4 is single piston double-acting type hydraulically extensible oil cylinder.
The effective travel of described hydraulically extensible oil cylinder 4 is 0-800mm.
Principle of work of the present utility model: the rear support leg casing links to each other with big of chassis by flexible casing, and hydraulically extensible oil cylinder one end is connected with rear support leg casing middle part, and the hydraulically extensible oil cylinder other end links to each other with big of chassis.Finish by flexible casing big of rear support leg casing and both sides, and the mobile oil cylinder that adopts of casing is finished, and narrow space, lifting highly are not under the very high situation, the supporting leg span under the situation about not requiring, and the rear support leg casing keeps original position; Increase span if desired, the rear support leg casing under the effect of hydraulically extensible oil cylinder, after move maximum removable 800mm as required.
The beneficial effects of the utility model are: 1, simple in structure, cost is low, flexible and convenient operation.2, flexible casing can be made the multi-joint telescoping formula according to the span needs, satisfies to increase the requirement of hoisting crane span, thereby significantly improves stability and the resistance to capsizing of hoisting crane, to satisfy the requirement of different operating modes.
