The invention provides a telescopic supporting leg structure. The telescopic supporting leg structure comprises a horizontal supporting leg, a vertical supporting leg, a horizontal telescopic oil cylinder, a vertical telescopic oil cylinder and a vertical telescopic oil cylinder connecting oil way. The horizontal supporting leg comprises a fixed supporting leg and a horizontal telescopic supporting leg; the vertical supporting leg is connected with the horizontal telescopic supporting leg; a cylinder barrel of the horizontal telescopic oil cylinder is connected with the horizontal telescopic supporting leg, and a cylinder rod is connected with the fixed supporting leg. The vertical telescopic oil cylinder is arranged in the vertical supporting leg; the vertical telescopic oil cylinder connecting oil way comprises a fixed oil pipe, a movable back-bending hydraulic rubber pipe and a connecting oil pipe. The fixed oil pipe is arranged on a cylinder barrel of the horizontal telescopic oil cylinder; the movable back-bending hydraulic rubber pipe is located on the side away from the vertical supporting leg and communicates with the fixed oil pipe. The fixed oil pipe is communicated with the vertical telescopic oil cylinder through the connecting oil pipe. Meanwhile, the invention further provides an overhead working truck. Compared with the prior art, the telescopic supporting leg structure and the overhead working truck can better avoid the abnormal conditions of knotting, pulling, winding and the like of the rubber pipe.
本发明提供了一种伸缩支腿结构,其包括水平支腿、垂直支腿、水平伸缩油缸、垂直伸缩油缸、垂直伸缩油缸连接油路;水平支腿包括固定支腿及水平伸缩支腿;垂直支腿与水平伸缩支腿连接;水平伸缩油缸缸筒与水平伸缩支腿连接,缸杆与固定支腿连接;垂直伸缩油缸设置于垂直支腿内;垂直伸缩油缸连接油路包括固定油管、活动回弯液压胶管、连接油管;固定油管设置于水平伸缩油缸的缸筒上;活动回弯液压胶管位于远离垂直支腿的一侧,并与固定油管连通;连接油管将固定油管与垂直伸缩油缸连通。同时,还提供了一种高空作业车。与现有技术相比,本发明提供的伸缩支腿结构及高空作业车可以更好的避免胶管出现打结、拉扯、缠绕等异常情况。
