Abstract

The invention provides a tunnel steel arch installation car. The tunnel steel arch installation car comprises a mainframe platform, a chassis, mechanical arms and grabbing hands, wherein the chassis is arranged on the bottom of the mainframe platform, the mechanical arms are arranged on the mainframe platform, and the grabbing hands are arranged at tail ends of the mechanical arms. By means of thetunnel steel arch installation car, an overall steel arch which is already subjected to butt joint assembly on the ground can be lifted, and can be installed in a position needed for a tunnel so thatthe labor intensity can be reduced, and installation of the steel arch is made to be fast and safe.

Description

technical field [0001] The invention belongs to the technical field of tunnel steel arch installation equipment, and in particular relates to a tunnel steel arch installation trolley. Background technique [0002] In the drilling and blasting tunnel construction, when the surrounding rock with poor self-stability is encountered, it is necessary to carry out initial support immediately after the excavation process, install steel arches, hang nets, and carry out concrete spraying operations to consolidate the tunnel and prevent the tunnel from collapsing. . The installation of steel arches usually divides each couch into sections, and the steel arches connected by flange bolts between each section are installed on the circular excavation surface of the tunnel, and are welded and positioned with the anchor rods driven into the surrounding rock in advance. The current steel arch installation usually uses a simple steel platform as a platform to move and place each section of st...
