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
[0108] Specific embodiment: when the lifting winding wheel 20 is not rotating, the suspension plate 17 is located at the bottom of the rectangular guide hole and the rectangular guide groove 41; When entering the corresponding second engaging slot 92, the fifth guide block spring 85 is compressed.
[0109] 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...

The invention belongs to the technical field of fire fighting, and particularly relates to a high-rise safe auxiliary lifting mechanism based on an aerial ladder fire truck. The high-rise safe auxiliary lifting mechanism based on the aerial ladder fire truck comprises a hook, a hanging plate, a shell, a lifting block, lifting winding wheels, volute spiral springs, a connecting rod, centrifugal block springs, first clamping grooves, a lifting mechanism and the like. According to the high-rise safe auxiliary lifting mechanism based on the aerial ladder fire truck, the lifting mechanism can be driven by a motor to drive a bucket rotating platform to continue to move upwards so as to rescue persons who are trapped in the higher positions and cannot be rescued by the aerial ladder fire truck. Meanwhile, when the auxiliary lifting mechanism has an emergency, the lifting mechanism can still play a basic role in dealing with the emergency, and the situation that the trapped persons are injuredagain when encountering the emergency is avoided. The high-rise safe auxiliary lifting mechanism based on the aerial ladder fire truck is simple in structure and safe, and has a 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 safety auxiliary lifting mechanism 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 ...
