The invention provides a fire fighting truck ladder assembly structure and a fire fighting truck, and relates to the technical field of fire fighting. The fire fighting truck ladder assembly structure comprises a rotary support, a telescopic ladder assembly, a supporting support and a rotary driving source. The telescopic ladder assembly is located above the rotary support in the first direction. The supporting bracket is arranged on the telescopic ladder frame and is rotationally connected to the rotary bracket; the fixed end of the rotary driving source is rotationally connected to the rotary support, the output end of the rotary driving source is rotationally connected to the supporting support, and the rotary driving source drives the telescopic ladder assembly to rotate relative to the rotary support through the supporting support; and the rotary connection position between the output end of the rotary driving source and the supporting bracket is higher than the bottom surface of the extension ladder frame in the first direction. By changing the rotary connection position between the output end of the rotary driving source and the supporting bracket, the bearing performance of the supporting bracket on the extension ladder assembly is improved, so that the extension ladder assembly can rise and fall in a full extension state, and even full extension rescue at a negative angle can be realized.
本发明提供一种消防车梯架结构及消防车，涉及消防技术领域。该消防车梯架结构包括回转支架、伸缩梯架、支撑支架和旋转驱动源，伸缩梯架位于回转支架沿第一方向的上方；支撑支架设置于伸缩梯架并转动连接于回转支架；旋转驱动源的固定端转动连接于回转支架，旋转驱动源的输出端转动连接于支撑支架，旋转驱动源通过支撑支架驱动伸缩梯架相对于回转支架转动；其中，旋转驱动源的输出端和支撑支架之间的转动连接位置高于伸缩梯架沿第一方向的底面。通过改变旋转驱动源的输出端和支撑支架之间的转动连接位置，增加了支撑支架对伸缩梯架的承载性能，从而可以实现伸缩梯架在全伸展状态下升起和降落，甚至是在负角度下全伸式救援。
