A highway-railway dual-purpose overhead working truck is used for overhead maintenance and rescue. The highway-railway dual-purpose overhead working truck consists of a highway-railway dual-purpose vehicle which is used for bearing and installing an operation mechanism and achieving the highway-railway dual-purpose walking maneuvering function, an operation mechanism which is used for achieving the lifting and folding functions of an operation platform, and a hydraulic control system which is used for achieving lifting, folding and position adjustment of the operation mechanism and conversioncontrol over a highway-railway walking mechanism, wherein a chassis is provided with a rail wheel walking mechanism and a rubber wheel walking mechanism; the operation mechanism is fixedly connected to the frame through a rotary support, and an operation hanging basket is hinged and fixed to the rear end of the operation mechanism. The operation mechanism is unfolded under the operation working condition, the operation hanging basket is lifted for aloft work, the operation mechanism is folded and falls back to the frame to be stably supported under the non-operation working condition, and maneuvering walking and warehousing are facilitated. The highway-railway dual-purpose overhead working truck is flexible, easy to operate, safe and reliable due to the fact that the operation mechanism and the walking mechanism are locked hydraulically, and can be widely applied to maintenance and rescue operation of railways, highways and indoor high-altitude facilities.
一种公铁两用高空作业车,用于高空维护和救援。由用于作业机构的承载和安装、并实现公铁两用行走机动功能的公铁两用车、用于实现作业平台升降和折叠收拢功能的作业机构、用于实现作业机构的升降、折叠和位置调整及公铁路走行机构转换控制的液压控制系统组成;底盘上带有轨轮行走机构与胶轮行走机构,作业机构通过旋转支承与车架连接固定,作业吊篮铰接固定于作业机构的后端。本发明作业工况时作业机构展开,举升作业吊篮进行高空作业,非作业工况时作业机构折叠收拢回落于车架上支稳,便于机动行走和入库。机动灵活,操作简单,作业和行走机构通过液压锁定,吊篮式作业平台安全可靠。可广泛应用于铁路、公路及室内高空设施维护和救援作业。
