Abstract

The embodiment of the invention discloses a multi-stage hydraulic multiplying pulley vertical lifting platform fire truck, which belongs to the technical field of fire fighting and rescue equipment, and includes a car chassis, the tail of the car chassis is hingedly equipped with a telescopic arm, and the top end of the telescopic arm is A slewing platform is provided, and a working arm is installed on the slewing platform, and a working bucket is installed on a section of the working arm; Front hydraulic outriggers are installed on the left and right sides, and rear hydraulic outriggers are installed on the left and right sides of the telescopic arm away from the cab of the car. The chassis of the car is provided with an auxiliary support oil cylinder. Each is equipped with a transitional hydraulic cylinder. The invention solves the technical problems that the maximum rescue radius of the existing high-altitude fire truck is small, and the maximum rescue height is greatly limited by the transmission form of the hydraulic oil cylinder, and is widely used in high-altitude fire fighting or rescue.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of fire fighting and rescue equipment, in particular to a multi-stage hydraulic multiplying pulley vertical lifting platform fire truck. Background technique [0002] With more and more high-rise buildings, the building height of high-rise buildings is far greater than the lifting height of fire rescue vehicles. The length is 18.9 meters, the width is 2.5 meters, the height is 4 meters, the maximum height fire rescue radius is 6 meters, and the turning radius is large. This kind of behemoth needs enough road turning to enter the residential complex. In the current dense building complex, this kind of rescue vehicle It cannot be driven in, and when the vehicle-mounted crank-arm turning structure is working, it is necessary to use hydraulic outriggers to stabilize the vehicle as a whole, resulting in large hydraulic power; the crank-arm turning mechanism is located on the car, with a ...
