The Modified Design on the Cantilever Machine Supporting the Roof Frame Anchor System

Abstract

Basedon the present situation of the domestic comprehensive tunneling temporary supporting technology, machine support and temporary support device is researched. This paper is on the basis of the previous design simple optimization.The design enhances temporary support level and improves its ability to support for a long time, in some extent, increases the strength of roof support. The optimization is described in detail.By adding a hydraulic cylinder,it can make each lever own supporting ability and ensure support stability. Organizationstructure and three dimensional graphics are drawn in the paper.The force analysis is carried. Finally appropriate position is determined.
