Abstract

The invention belongs to the technical field of fire-fighting equipment, and particularly relates to a fire-fighting aerial ladder. For solving the problems in the prior art, the following scheme is and provided that the fire-fighting aerial ladder comprises a base and a working bucket, a first ladder frame is rotatably connected to one side of the outer wall of the bottom of the working bucket, at least two second ladder frames which are slidably connected into a whole are arranged between the first ladder frame and the base, the first ladder frame is slidably connected to the inner wall of the side face of the uppermost second ladder frame, the bottom end of the lowermost second ladder frame is rotatably connected to the outer wall of the top of the base, sliding plates are laid on the inner walls of the bottoms of the first ladder frame and the second ladder frame, and a baffle is fixedly connected to the bottom end of the lowermost second ladder frame. According to the fire-fighting aerial ladder, rescue efficiency is improved, a buffer air cushion can achieve a buffer effect, then personnel can be prevented from being injured, the situation that the personnel slide down too fast and are injured can be prevented, the speed of the personnel sliding to the bottom end can be reduced, safety is further improved, and the working bucket can be kept in a horizontal state all the time.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting aerial ladder. Background technique [0002] The aerial 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. There is a telescopic aerial ladder on the car. Equipped with lift bucket turntable and fire extinguishing device, it is used for firefighters to ascend to put out fires and rescue trapped people, and is suitable for fighting fires in high-rise buildings. [0003] When the existing aerial ladder fire truck is in use, when it is necessary to rescue people at high altitude, due to the limited space of the working bucket of the fire fighting aerial ladder, when the working bucket is full, it needs to be lowered to unload the personnel to carry out the ...
