Abstract

The invention discloses a multifunctional tunnel arch erecting machine which comprises a movable trolley and a supporting frame. The supporting frame is fixedly connected to the movable trolley, and the movable trolley drives the supporting frame to move in a multi-dimensional mode. The supporting frame is provided with at least two arch frame clamping assemblies used for clamping and fixing arch frame sections, and the arch frame clamping assemblies drive the arch frame sections on the arch frame clamping assemblies to stretch out and draw back in the radial direction of the cross section of the tunnel. By means of the arch erecting machine, stretching and moving of arch frame sections can be achieved, the functions are diversified, the installation efficiency and the installation quality of tunnel steel arch frames are greatly improved, the whole process is completed mechanically, and safety is high.

Description

technical field [0001] The invention relates to the field of tunnel steel arch assembly, in particular to a multifunctional tunnel arch erecting machine. Background technique [0002] The general process of tunnel formation: first spray out the rock face, then set up the steel arch frame, install the locking anchor rod, hang the steel mesh, install the system anchor rod, install the anchor pad for reinforcement, and finally spray the grout to the design thickness. In the prior art, multiple steel arch segments are directly arranged in the tunnel, and then assembled and welded to form a complete arch. Due to the narrow space inside the tunnel, the installation of the steel arch is limited. Large, thus affecting the assembly efficiency and quality of the steel arch. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a multifunctional tunnel erecting machine with high installation effic...
