The invention relates to a novel stable variable aerial ladder. The novel stable variable aerial ladder comprises a base, a cavity is formed in the base, a servo motor is fixedly connected to the inner side wall of the cavity, a lead screw is fixedly connected to the output end of the servo motor, and the end, away from the servo motor, of the lead screw penetrates through the side wall of the base and extends outwards; and the lead screw is connected with a sliding rod through a sliding device, the lead screw is connected with a winding drum through a linkage device, a rope is arranged on the winding drum, an aerial ladder assembly is arranged on the base, the aerial ladder assembly is connected with a handrail through a buffering device, and the free end of the rope is connected with the handrail. Through rotation between a linkage rod and a fixing rod, two adjacent rectangular frames are close to or away from each other, when the adjacent rectangular frames are close to each other, the whole aerial ladder assembly is in a storage state, the size is reduced, the occupied space is reduced, movement is convenient, and disaster relief can be achieved in time.
Description
technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a novel stable and variable fire-fighting aerial ladder. Background technique [0002] The ladder fire truck is equipped with a hydraulically raised 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. There is a lifting bucket turntable for firefighters to climb up to put out fires and rescue trapped people, and is suitable for fighting fires in high-rise buildings; [0003] Most of the existing fire-fighting aerial ladders are large in size, lack of storage function, and require large vehicles to provide support, which inevitably requires a large space for turnover. Necessary loss, and the existing fire-fighting aerial ladder lacks supporting facilities such as ropes, most of which require firefighters to carry ropes to re...
