Subway tunnel lining trolley

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of subway tunnel construction, in particular to a subway tunnel lining trolley. Background technique [0002] The subway tunnel construction trolley is a special equipment used in the secondary lining during the tunnel construction process, and is used for the lining construction of the inner wall of the tunnel. At present, due to differences in construction environment and construction requirements, the cross-sectional profiles of subway tunnels in my country are often different. Therefore, all parts of the lining trolley need to be redesigned and processed according to different profiled cross-sections, which greatly increases the design cycle and processing cycle. In addition, the contour section of the subway tunnel is small, and the tunnel lining trolley in the prior art has a small headroom and a small amount of demoulding, and the lining trolley cannot pass even a small loader during tunnel constructi...

AI Technical Summary

Problems solved by technology

At present, due to differences in the construction environment and construction requirements, the cross-sectional profiles of subway tunnels in my country are often different, so all parts of the lining trolley need to be redesigned and processed according to different profile cross-sections, thus greatly increasing the design cycle and processing cycle.

In addition, the contour section of the subway tunnel is small, and the tunnel lining trolley in the prior art has a small headroom and a small amount of demoulding, and the lining trolley cannot pass even a small loader during tunnel construction, thus making it difficult for the tunnel construction. It brings great inconvenience and prolongs the period of tunnel construction
