Abstract

The invention discloses a tunnel arch frame multi-shaft clamping and fixing device which is applied to a tunnel arch erecting machine and comprises a telescopic large arm, a telescopic small arm and a clamping mechanism; the telescopic small arm is connected to the front end of the telescopic large arm in a sliding mode, the telescopic small arm is driven by a telescopic driver to stretch out and draw back, the front end of the telescopic small arm is rotationally connected with a pitching base, the pitching base is driven by a first pitching driver to do pitching motion, the front end of the pitching base is rotationally connected with a rotating table, and the rotating table is driven by a first rotating driver to rotate, the clamping mechanism comprises a front end connected to the rotating table, the clamping mechanism comprises a panel, the panel is rotationally connected to the rotating table, the panel is driven by a second rotating driver to rotate, and at least one clamp used for clamping an arch frame segment is arranged on the upper portion of the front end face of the panel. The mounting efficiency and the mounting quality of the tunnel steel arch can be improved, the whole process is completed mechanically, and the safety is high.

Description

technical field [0001] The invention relates to the field of assembling tunnel steel arches, in particular to a multi-axis clamping and fixing device for tunnel arches. 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 an efficient and high-quality multi-axis clamping and f...
