Problems solved by technology

[0002] During the construction of the traditional lining trolley, the trolley portal frame is a force-bearing part. It is subjected to a large lateral pressure, and deformation varies with the stiffness of the portal frame, and it is not suitable for direct work in tunnels with large transverse and longitudinal slopes. , has higher requirements on the working environment, otherwise it will cause the overall deformation and damage of the trolley

Abstract

The invention discloses a hydraulic self-propelled steel form carrier for tunnel secondary lining operation. A travelling system is driven by a hydraulic system to move on steel rails, a backform frame body assembly is erected on a platform beam through a backform column and is driven by a jacking oil cylinder, the platform beam is arranged on a gantry beam through a jack frame in the middle, the gantry beam is erected on a middle beam through a middle column, gantry columns are respectively arranged on the two end parts of the middle beam, the gantry columns and a side form assembly are provided with a plurality of side form lead screws and reinforcement lead screws, the two ends of the side form lead screws are respectively hinged with the gantry columns and the side form assembly, and a bottom longitudinal beam is arranged below the gantry columns. The gantry frame of the hydraulic self-propelled steel form carrier for tunnel secondary lining operation is a non-stress part during the construction and is only stressed during erecting form removing and travelling processes; and when the hydraulic self-propelled steel form carrier constructs or travels in a ramp tunnel, the jacking oil cylinder on the lower part of the gentry frame is used for regulating the height, so that the whole carrier body is positioned in a horizontal state and does not have forward inclining force and side inclining force, and the whole stability of the carrier is ensured.

Description

technical field [0001] The invention relates to a tunnel construction machine, in particular to a hydraulic self-propelled steel mold trolley for secondary lining operation of a tunnel. Background technique [0002] During the construction of the traditional lining trolley, the trolley portal frame is a force-bearing part. It is subjected to a large lateral pressure, and deformation varies with the stiffness of the portal frame, and it is not suitable for direct work in tunnels with large transverse and longitudinal slopes. , It has high requirements on the working environment, otherwise it will cause the overall deformation and damage of the trolley. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention aims to provide a hydraulic self-propelled steel mold trolley for secondary lining operation of tunnels with simple positioning, fast adjustment of lining geometric position and high working efficiency. [0004] The inv...
