Rail supporting column suitable for fourth-rail backflow and used for urban rail transit vehicle base
The invention discloses a rail supporting column suitable for fourth-rail backflow and used for an urban rail transit vehicle base. The rail supporting column comprises steel structure stand columns of a rail bridge, and further comprises a travelling steel rail, and is characterized by further comprising a contact rail and a transition bracket, wherein the contact rail is a fourth rail, and is mounted on outer side vertical surfaces of the steel structure stand columns of the rail bridge through the transition bracket; the transition bracket achieves insulating effect among the contact rail and the steel structure stand columns of the rail bridge; the travelling steel rail is not electrified all the time; urban rail transition vehicles are pulled by an overhead contact net to supply power; and current is returned through the fourth rail. The fourth rail is supported by the rail bridge structure, and current returns to a traction substation through a special rail, so that safety and service lives of a vehicle base rail bridge, electromechanical equipment, a civil engineering structure and other pipelines can be greatly improved and prolonged. The fourth rail does not need to buildwith the steel structure stand columns additionally to mount, so that maintenance operation space is effectively expanded, and construction cost is greatly reduced.
本发明公开了一种适用于第四轨回流的城市轨道交通车辆基地轨道支撑柱，包括轨道桥的钢结构立柱和走行钢轨，其特征在于：还包括接触轨和过渡支架；接触轨作为第四轨，通过过渡支架安装在轨道桥的钢结构立柱的外侧立面，过渡支架在接触轨与轨道桥的钢结构立柱之间起到绝缘作用；走行钢轨始终不带电，城市轨道交通车辆通过架空接触网进行牵引供电，电流通过第四轨进行回流。通过该轨道桥结构，对第四轨进行支撑，电流经过专用轨回流至牵引变电所，可大幅度提高车辆基地轨道桥、机电设备、土建结构及沿线其他管线的安全和使用寿命。第四轨无需额外建设钢结构立柱进行安装，有效地拓展了检修作业空间，极大地节约了建设成本的投入。
