Problems solved by technology
The vehicle is equipped with a telescopic aerial ladder, which can be equipped with a lifting bucket turntable and a fire extinguishing device, for firefighters to climb up to put out fires and rescue trapped people. It is suitable for fighting fires in high-rise buildings; however, the lifting of the aerial ladder fire truck is limited. Let the aerial ladder fire truck rescue the trapped people at higher places, so it is necessary to design a lifting mechanism that can assist the aerial ladder fire truck

specific Embodiment approach
[0085] Specific implementation method: when the hook 16 is not hooked with the annular hook sleeve 9 , the suspension plate 17 is located at the bottom of the rectangular guide hole and the rectangular guide groove 41 .
[0086] When a fire breaks out in a high-rise building and the bucket turntable 5 on the aerial ladder fire truck 2 reaches the highest rescue height, one end of the first steel wire rope 53 is installed on the first coil wire rope groove 60, and one end of the second steel wire rope 54 is installed on the second coil. On the wire rope groove 61, the hook 16 hooks the annular hook sleeve 9; after the motor 10 starts, the motor 10 drives the platform winding wheel 13 to rotate through the first shaft 15, and the platform winding wheel 13 winds the first wire rope 53 and the second wire rope 54, The first steel wire rope 53 wound on a lifting winding wheel 62 and the second steel wire rope 54 wound on the second lifting winding wheel 63 are slowly released, and t...

The invention belongs to the technical field of fire fighting, and particularly relates to a high-rise auxiliary lifting mechanism based on an aerial ladder fire truck. The high-rise auxiliary liftingmechanism comprises a hook, a suspending plate, a shell, a lifting block, a lifting winding wheel, a volute spiral spring, a connecting rod, centrifugal block springs, a first clamping groove, a lifting mechanism and the like. According to the high-rise auxiliary lifting mechanism based on the aerial ladder fire truck, a bucket rotating table can be driven by a motor to move upwards so as to rescue stranded persons who are unable to be rescued by the ladder truck at a higher place by the lifting mechanism, at the same time, when the auxiliary lifting mechanism encounters an emergency, the lifting mechanism can still play a basic role in responding to the emergency, and the stranded persons are prevented from being injured again in the emergency. The high-rise auxiliary lifting mechanism based on the aerial ladder fire truck has simple structure, safety and good practical effect.
Description
technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to an auxiliary lifting mechanism for high-rise buildings based on a ladder fire truck. Background technique [0002] At present, the ladder fire truck is equipped with a hydraulic lifting platform for firefighters to climb up and fight fires in high-rise buildings, tall facilities, oil tanks, etc., rescue trapped people, rescue valuable materials and complete other rescue tasks. The vehicle is equipped with a telescopic aerial ladder, which can be equipped with a lifting bucket turntable and a fire extinguishing device, for firefighters to climb up to put out fires and rescue trapped people. It is suitable for fighting fires in high-rise buildings; however, the lifting of the aerial ladder fire truck is limited. Let the aerial ladder fire truck rescue the trapped people at higher places, so it is necessary to design a lifting mechanism that can assist the aerial...
