The aerial work platform for railway tunnel maintenance comprises a chassis, a lifting mechanism and a work platform, and the work platform is installed on the chassis in a lifting mode through the lifting mechanism; rail supporting leg assemblies of the same structure are arranged on the left side and the right side of the chassis respectively, each rail supporting leg assembly comprises a telescopic supporting leg assembly and a rail pulley, and the rail pulleys are connected with the chassis in a lifting mode through the telescopic supporting leg assemblies and can roll on the rails in the extending direction of the rails. The device has the beneficial effects that the device can be quickly and accurately moved to the rail and can be quickly withdrawn from the rail; compared with an existing aerial work platform in the tunnel, the cost is low; a hydraulic leveling system is additionally arranged in a working hydraulic system of the whole machine, so that the leveling function of the working platform is realized, and the safety and adaptability of the whole machine are improved; the control scheme of the whole machine is optimized through the three-position four-way electromagnetic proportional directional valve and the priority valve, and the safety of leveling and operation of the whole machine is ensured.

    本发明公开了一种用于铁路隧道养护的高空作业平台,包括底盘、升降机构和作业平台,所述作业平台通过升降机构可升降式安装在底盘上;底盘左右两侧分别设有结构相同的轨道支腿总成,轨道支腿总成包括伸缩支腿组件和轨道滑轮,所述轨道滑轮通过伸缩支腿组件可升降式与底盘连接,所述轨道滑轮可以沿铁轨延伸方向在铁轨上滚动。有益效果:本发明能够快速准确的移动至铁轨上,并且能够快速撤离铁轨;相对于现有隧道内的高空作业平台成本较低;通过在整机工作液压系统中增加液压调平系统实现了作业平台的调平功能,提高了整机的安全性和适应性;通过三位四通电磁比例换向阀和优先阀优化了整机的控制方案,确保整机调平和运行的安全性。
