Subway tunnel lining trolley

The invention relates to the technical field of subway tunnel construction, and provides a subway tunnel lining trolley. On the premise that portal units and supporting accessory units are certain, a bracket unit and template units are specifically designed, and therefore it is guaranteed that the trolley is suitable for subway tunnels with different profile sections. Portal vertical columns are in an inclined structural mode, the length of a portal beam meets requirements, and space between the portal vertical columns and portal longerons is increased; the two ends of the portal beam are designed to be in a stepped shape, portal upper longerons are installed in steps, and therefore the installation height of the portal upper longerons is reduced; the clearance of the portal units is increased through the design. In addition, small moving dies are designed in a bottom chamfer structural mode; the portal longerons are lengthened in the tunnel length direction, and a deforming mechanism and a climbing mechanism are installed on the portal longerons; the demold amount of the trolley is increased through the design, and it is guaranteed that the template units do not easily interfere with the deforming mechanism or the climbing mechanism in the die assembly process.
