The invention provides a maintenance floor structure of an urban rail vehicle, which is characterized in that a plurality of maintenance holes are formed in a vehicle body chassis aluminum structure, sealing frames are fixed in the maintenance holes, and detachable maintenance floors are embedded in the sealing frames; and a detachable aluminum honeycomb floor which is detachably connected with the surrounding aluminum honeycomb floor is arranged above the detachable maintenance floor. The detachable maintenance floor is fixed in the sealing frame through folding bolts. And the detachable aluminum honeycomb floor is fixed on the surrounding aluminum honeycomb floor through the four-corner lock. When the internal combustion power pack needs to be overhauled, the four-corner locks on the detachable aluminum honeycomb floor are punched, then the folding bolts are loosened, and then the detachable overhauling floor is detached, so that the diesel engine of the internal combustion power pack can be overhauled on the vehicle, the maintainability is high, the operation is simple, and the workload of maintaining and replacing equipment is greatly reduced.
本发明提供一种城轨车辆的检修地板结构,加工在车体底架铝结构上的多个检修孔,检修孔内固定有密封框架,所述密封框架内嵌入有可拆卸检修地板;所述可拆卸检修地板的上方布置有与周围铝蜂窝地板可拆卸连接的可拆卸铝蜂窝地板。可拆卸检修地板通过折叠螺栓固定在密封框架内。可拆卸铝蜂窝地板通过四角锁固定在周围铝蜂窝地板上。当需要检修内燃动力包时,先将可拆卸铝蜂窝地板上的四角锁打卡,再松开折叠螺栓,然后拆卸可拆卸检修地板,即可在车上对内燃动力包的柴油机进行检修任务,可维护性强,操作简单,大大减少维修和更换设备的工作量。
