Abstract

The invention discloses automatic tunnel assembling type preliminary bracing installation equipment. The automatic tunnel assembling type preliminary bracing installation equipment comprises a transverse moving trolley, a base movably connected with the top of the transverse moving trolley, multiple mechanical arms distributed in a sector radiation manner, a total station and a controller. Any mechanical arm is of a telescopic structure, a workpiece clamping mechanism is mounted on the end of each mechanical arm, a positioning target is mounted on the outer wall of a unit joint, the total station is used for measuring the outline of a tunnel rock face and coordinate value of all positioning targets, and the controller stores a plane hook face, a vertical hook face and section data of the preset tunnel rock face. The preliminary bracing installation equipment and a measuring technology are fused together, through measuring the absolute positions of the positioning targets, the mechanical arms are guided to be adjusted, the preliminary bracing in-place precision is improved, the automatic tunnel assembling type preliminary bracing installation equipment enables tunnel assembly type preliminary bracing work to be simpler and more convenient, and tunnel construction proceed can be quickened.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment. More specifically, the present invention relates to an automatic tunnel assembly type primary support installation device. Background technique [0002] The traditional initial support method of the tunnel is: after the excavation of the tunnel, the platform is in place, the arch is installed manually, and the concrete is sprayed. Due to the excavation of the tunnel, the original stable structure of the surrounding rock is broken. During the stress release process, it is very easy to cause the phenomenon of block falling, and for some sections with soft surrounding rock, it may also lead to local collapse. The falling blocks and slipping that break in will bring life danger to the workers. [0003] Conventional arch installation requires 6-8 workers, and the installation time is roughly 3-4 hours. How to overcome the casualties caused by the sudden falling and sliding of ...
