Problems solved by technology

However, most of the existing elevating fire trucks have the following defects: the X outriggers must have an intersection point, and must be divided into upper and lower layers in the height direction, so the height of each layer is very limited, and the top and bottom plates need thicker plates, otherwise the stress will It will be very large, and the weight of the outrigger is heavy; the X outrigger or H leg takes up a lot of space, and a large space is needed for climbing the fire fighting site; the X outrigger is very limited in length due to the width limitation of the chassis, and it is difficult to be suitable for a long boom The demand for large-span fire trucks; fixed outriggers are only used for small-span fire trucks with short booms; X outriggers and H telescopic legs limit the flexibility and mobility of fire trucks, and a large space is required to fight, and the combat After a fixed fire extinguishing or demolition point, and it is difficult to move, it cannot work continuously
[0003] In the related art, the pump truck is provided with an intermediate part between the chassis and the boom system, the chassis and the middle part are rotatably connected, and the center of gravity of the chassis and / or the middle part deviates from the rotation center line of the chassis and the middle part, without increasing In the case of extra counterweight, use the chassis and / or intermediate parts of the pump truck itself as the counterweight to flexibly adjust the center of gravity of the pump truck, but the pump truck is essentially just a top-loaded slewing mechanism, which is a first-stage slewing mechanism, and the efficiency is not high

Abstract

The invention provides a vehicle. The vehicle comprises a chassis, a support frame assembly, a slewing platform and a boom system, wherein the support frame assembly is movably arranged on the chassis; the slewing platform is arranged on the support frame assembly; the boom system is arranged on the slewing platform; the boom system and the slewing platform are rotatably connected through a firstslewing bearing; the slewing platform and the support frame assembly are rotatably connected through a second slewing bearing. According to the vehicle provided by the invention, the first slewing bearing and the second slewing bearing are matched to form a two-stage slewing mechanism, and the two-stage slewing mechanism is matched with the support frame assembly to ensure that the chassis, the support frame assembly and the slewing platform of the vehicle can be used as counterweights to flexibly adjust the gravity of the vehicle to increase the stability of the vehicle, thereby avoiding theuse of legs or reducing the lengths of the legs, achieving a best weighting effect and improving the stability of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of engineering machinery, in particular to a vehicle. Background technique [0002] At present, most of the outriggers for elevating fire trucks adopt the following structural forms: H telescopic outriggers, X outriggers, swing legs, and fixed outriggers. Before raising the fire truck to fight, the four outriggers spread out to support the ground to form a square or trapezoid, which is used to bear the weight of the whole vehicle and the boom system (including boom, connecting rod) during the process of raising the fire truck for fire fighting or demolition. , Oil cylinders, water pipes, fire monitors and demolition tools) to prevent overturning. However, most of the existing elevating fire trucks have the following defects: the X outriggers must have an intersection point, and must be divided into upper and lower layers in the height direction, so the height of each layer is very limited, and the t...
