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

[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 protection, and particularly relates to high-rise auxiliary lifting equipment based on an aerial ladder fire truck. The equipment comprises a hook,a hanging plate, a shell body, a lifting block, a lifting winding wheel, a scroll spring, a connecting rod, centrifugal block springs, a first clamping groove, a lifting mechanism and the like. According to the equipment, the lifting mechanism can drive a bucket turntable to continue to move upwards under the driving of a motor to rescue the trapped person who cannot be rescued by the aerial ladder fire truck at a higher altitude, meanwhile, when an auxiliary lifting mechanism encounters burst conditions, the lifting mechanism can still play a basic role in dealing with the burst conditions,and the situation that the trapped person is injured again when encountering the burst conditions is avoided. The equipment has the advantages of 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 a high-rise auxiliary lifting device 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 ladder fire truck...
