The invention relates to the technical field of high-altitude operation, in particular to a supporting leg assembly, a high-altitude operation vehicle and a safe operation method of the high-altitude operation vehicle. The supporting leg assembly comprises a horizontal supporting leg assembly and a vertical supporting leg assembly; the horizontal supporting leg assembly comprises a horizontal supporting leg, a horizontal supporting leg box and a pressure sensor; the horizontal supporting leg can be horizontally and movably connected to the horizontal supporting leg box in a penetrating mode, the tail end of the horizontal supporting leg is in abutting contact with the bottom wall of the horizontal supporting leg box through a pressure sensor, and the head end of the horizontal supporting leg is connected with the vertical supporting leg assembly. According to the invention, the extension amount of the horizontal supporting leg can be calculated in real time only by means of the pressure sensor, so that the maximum operation range of the cantilever crane is obtained, the operation safety is ensured, the performance of the overhead working truck is brought into full play, and meanwhile, the influence on traffic is reduced; in addition, the pressure sensor can reflect the supporting force of the vertical supporting leg assembly and judge whether the vertical supporting leg assembly is in a virtual leg state or not, design is ingenious, cost is low, and the effect of guiding the overhead working truck to conduct safe operation is achieved through an extremely simple structure.
本发明涉及高空作业的技术领域,具体提出了一种支腿组件、高空作业车及其安全作业方法。支腿组件包括水平支腿组件和竖直支腿组件,水平支腿组件包括水平支腿、水平支腿箱和压力传感器;水平支腿可水平移动地穿接于水平支腿箱,且其末端通过压力传感器与水平支腿箱的底壁抵压接触,其首端与竖直支腿组件连接。在本发明中,仅仅依靠压力传感器,便能实时计算出水平支腿的伸出量,从而获得臂架的最大作业范围,既保证作业安全,又使高空作业车的性能充分发挥,同时减小对交通的影响;另外,压力传感器还可反映竖直支腿组件的支撑力,判断是否为虚腿状态,设计巧妙,成本较低,以极为精简的结构实现了指导高空作业车进行安全作业的效果。
