Straddle carrier is the main force's type in container handling device, generally undertakes the container stack work in the horizontal transport by wharf apron to stockyard and stockyard.Due to straddle carrier there is maneuverability, the feature such as efficiency height, good stability, wheel force down, obtain universal application, straddle carrier operation is highly beneficial to the efficiency of loading and unloading improving wharf apron equipment.
At present, existing straddle carrier structure is fixed, is only suitable only in outdoor spacious stockyard work, it is impossible to load and unload in entering the place that the chamber height such as workshop, warehouse is limited.
Summary of the invention
It is an object of the invention to provide the straddle carrier that a kind of height can lift.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of straddle carrier, including vehicle frame, it is connected to the elevating mechanism above described vehicle frame, it is connected to the walking mechanism below described vehicle frame and suspender, described elevating mechanism includes the one-level crane being connected on described vehicle frame, the two grades of cranes being connected on described one-level crane, second drive mechanism of two grades of cranes liftings described in the first drive mechanism of the one-level crane lifting described in driving and driving, the second described drive mechanism includes the pulley being arranged on described one-level crane, around the hauling rope being located on described pulley, the one end of described hauling rope is connected on described vehicle frame, the other end is connected on described two grade crane.
Preferably, described one-level crane, two grades of cranes are door-shaped frame, described door-shaped frame includes being positioned at the crossbeam of centre, being connected to lay respectively at bottom described crossbeam the supporting leg of both sides, and described suspender is connected on the crossbeam of described two grade crane.
It is further preferred that be fixed with guide pin bushing on described vehicle frame, the supporting leg of described one-level crane is arranged in described guide pin bushing and can slide up and down in described guide pin bushing.
It is further preferred that offer cavity on described one-level crane, the supporting leg of two grades of described cranes is arranged in described cavity and can slide up and down in described cavity.
It is further preferred that the first described drive mechanism, the second drive mechanism are symmetrically arranged with two.
Preferably, the first described drive mechanism includes that oil cylinder, the cylinder body of described oil cylinder are fixed on described vehicle frame, and the piston of described oil cylinder is connected on described one-level crane.
Preferably, described hauling rope is steel wire rope.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
The present invention coordinates pulley and hauling rope by cylinder jacking, makes car load lifting multiplying power promote, and car load height can be
2
The lifting of times cylinder jacking stroke, thus realize the regulation on straddle carrier whole height, makes the car can be with indoor scenarios work such as the limited workshop of entry altitude, warehouses.
