Fire fighting truck rotating ladder special for high-altitude rescue
The invention relates to a fire fighting truck rotating ladder special for high-altitude rescue. The fire fighting truck rotating ladder comprises a ladder frame, wherein a rescue platform is arranged at the upper end of the ladder frame, a rotating platform is arranged at the lower end of the ladder frame, the lower end of the ladder frame is rotationally connected with the rotating platform, the two sides of the ladder frame are each connected with a hydraulic cylinder, cylinder bodies of the hydraulic cylinders are rotationally connected to the rotating platform, telescopic rods of the hydraulic cylinders are rotationally connected to the ladder frame, the hydraulic cylinders extend, the horizontal included angle of the ladder frame is reduced, and the height of the rescue platform is reduced; the hydraulic cylinders are shortened, the horizontal included angle of the ladder frame is increased, and the height of the rescue platform is increased; and a rotation driving assembly is arranged at the bottom of the rotating platform and comprises a driving motor, a rotation gear and a rotation gear ring, and the upper surface of the rotation gear is fixedly connected to the lower surface of the rotating platform. The fire fighting truck rotating ladder has the technical effects that the certain rescue height is met, meanwhile, the stability of the high-altitude ladder frame is good, an upper end butt joint platform can be adjusted in four directions, maneuverability is high, and rapid positioning is facilitated.
本发明涉及一种高空救援专用消防车旋转梯，包括梯架，梯架的上端设置救援平台，梯架的下端设置旋转平台，梯架的下端与旋转平台转动连接，梯架的两侧分别连接有一个液压缸，液压缸的缸体转动连接在旋转平台上，液压缸的伸缩杆转动连接在梯架上，液压缸伸长，梯架的水平夹角减小，救援平台的高度降低；液压缸缩短，梯架的水平夹角增大，救援平台的高度升高；所述旋转平台的底部设置回转驱动组件，所述回转驱动组件包括驱动电机、回转齿轮和回转齿圈，所述回转齿轮的上表面固定连接在旋转平台的下表面。本发明满足一定救援高度的同时，兼具高空梯架稳定性好，上端对接平台可四向调节，机动性较强，便于快速定位的技术效果。
