Description
Technical field
The present invention relates to technical field of engineering machinery, in particular to a kind of vehicle.
Background technique
Currently, elevating fire truck supporting leg mostly uses greatly following several structure types: H telescopic outrigger, X supporting leg, swinging kick, fixation
Supporting leg.Make prewar in elevating fire truck, four supporting legs expansion support ground, composition one is rectangular or trapezoidal, for elevating fire truck into
Row fire extinguishing or forcible entry during bear vehicle self weight and boom system (including cantilever crane, connecting rod, oil cylinder, conveying water pipe, fire monitor and
Break-in tool) weight generate moment of flexure, prevent from toppling.But there are following defects mostly for existing elevating fire truck: X supporting leg is necessary
There is intersection point, upper layer and lower layer must be divided in the height direction, then each layer of height is very limited, and roof and floor needs thicker plate,
Otherwise stress will be very big, the heavier-weight of supporting leg；X supporting leg or H leg, occupied space is larger, place space needs of putting out a fire of ascending a height
Greatly；For X supporting leg since the width on chassis limits, length is extremely limited, is difficult the demand suitable for long cantilever crane large span fire fighting truck；It is fixed
Supporting leg is more served only for the small span fire fighting truck of galianconism frame；X supporting leg and H Retractive leg limit the flexibility and mobility of fire fighting truck, must
Need larger space could fight, and after fight a fixed fire extinguishing or forcible entry point, and mobile difficult, cannot continuously make well
Industry.
In the related technology, pump truck is provided with intermediate member, chassis and intermediate member between chassis and the boom system
Rotation connection, and the rotary centerline on the deviation of gravity center chassis and intermediate member of chassis and/or intermediate member, it is additional not increasing
In the case where counterweight, the center of gravity of pump truck, but the pump truck are adjusted flexibly using the chassis of pump truck itself and/or intermediate member as counterweight
The substantially only upper revolution filled, is level-one swing mechanism, inefficient.
Summary of the invention
The present invention is directed at least solve one of the technical problems existing in the prior art.
For this purpose, the present invention provides a kind of vehicles.
The present invention provides a kind of vehicles, comprising: chassis；Bracket assembly is movably arranged on chassis；Revolution is flat
