The invention discloses a climbing fire truck and a supporting leg telescopic device and method thereof. The supporting leg telescopic device for the climbing fire fighting truck comprises a supporting leg box arranged on a fire fighting truck frame, a first supporting leg sleeved with the supporting leg box in a sliding mode, a second supporting leg sleeved with the first supporting leg in a sliding mode, a first oil cylinder perpendicularly arranged at the free end of the second supporting leg, and a pressure sensor arranged between the first oil cylinder and the second supporting leg. A first support is fixed to one end of the supporting leg box, a second oil cylinder is fixed to the first support, and the second oil cylinder comprises a push rod connected to the first support and a cylinder barrel arranged on the outer side of the push rod in a sleeving mode. Through the effective weight reduction design and the installation structure, high smoothness, convenience and reliability are achieved, the stress of the supporting leg can be measured in real time by reading the numerical value of the pressure sensor in the use process, then it is confirmed that the first oil cylinder bears force correctly all the time and does not leave the ground, the actual use requirement can be better met, and the application range is wide. And the method has good practicability and adaptability.

    本发明公开了一种登高消防车及其支腿伸缩装置与支腿伸缩方法,用于登高消防车的支腿伸缩装置包括设置于消防车车架上的支腿箱、滑动套设于支腿箱内的第一支腿、滑动套设于第一支腿内的第二支腿、垂直设置于第二支腿自由端的第一油缸、设置于第一油缸与第二支腿之间的压力传感器,支腿箱一端固定有第一支座,第一支座固定有第二油缸,第二油缸包括连接于第一支座的推杆、套设于推杆外侧的缸筒;本发明通过有效的减重设计和安装结构具有很高的平顺性、便捷性和可靠性,通过在使用过程中读取压力传感器的数值可以实时测量支腿的受力大小,进而确认第一油缸始终正确承力且不离地,能够更好地满足实际的使用需求,具有良好的实用性与适应性。
