Abstract

The invention discloses a multifunctional support trolley for tunnel arches. A scissor lifting table is installed on a trolley platform, general purpose manipulators special for tunnels are installed on two sides of the trolley platform, each general purpose manipulator special for tunnels comprises a telescopic boom, one ends of the telescopic booms are mounted on telescopic boom rotating stands, and the telescopic boom rotating stands are provided with rotating seats and telescopic boom rotating hydraulic cylinders; and one ends of derricking cylinders are installed on the telescopic boom rotating stands, the other ends of the derricking cylinders are installed on the telescopic booms, and manipulators are installed at front ends of the telescopic booms. The multifunctional support trolley has the advantages that installation work of the arches can be finished only by three or four operators, and labor force is saved; the mechanized operation during installation of the arches can be achieved; I-beam arches and grid arches can be lifted to any position in tunnels after being clamped, and arches can be fine adjusted rapidly in all directions; general purpose manipulators special for left and right tunnels work simultaneously, so that rapid installation is facilitated, construction time is greatly saved, and the working efficiency is improved; and the scissor lifting table is installed on the trolley platform, so that other construction operations and tunnel defect treatment besides arch installation are facilitated.

Description

technical field [0001] The invention relates to a tunnel operation trolley. Background technique [0002] In the construction of hydropower tunnels, underground powerhouses, subway projects, railway tunnels, military underground projects, and highway tunnel projects, it is often necessary to erect steel arch grid arches and constructions in areas with poor self-stabilization capabilities such as broken surrounding rocks and faults. Anchor rods, hanging steel mesh, sprayed concrete and other means are used to reinforce the surrounding rock to ensure construction safety. Taking the installation of tunnel arches as an example, at present most of the installations of arches in China mainly rely on manual work. First of all, the arch frame is placed under the rock formation, fixed with anchor rods, and the multi-section arch frame is sequentially connected into a ring with bolts. During the construction process, the weight of a single arch section is as high as 200-400 kg, and ...
