TLDR
In this paper, a circular-rail multifunctional drill jumbo system at least comprises crawler track units, a portal frame, a circular rail system and an operating platform moving longitudinally along the portal frame.Abstract:
A circular-rail multifunctional drill jumbo system at least comprises crawler track units, a portal frame, a circular rail system and hydraulic drill rigs. The crawler track units form a four-point support jumbo on two sides of the portal frame, the circular rail system is mounted to the front end of the portal frame and supports the hydraulic drill rigs and a stand support device, and the system further comprises an operating platform moving longitudinally along the portal frame. Reliability and continuity in construction operation are improved effectively, the system adapts to full-face and bench-cut-method operation construction in tunnels, 80% of surrounding rock condition construction in a tunnel line can be completed, the crawler track units can realize efficient and flexible steering and balancing control, the system adapts to severe construction operation environments in the tunnels, the operation platform provides an operation platform for operators to approaching to the tunnel face to perform measurement, ruling, explosive filling and the like, the arch set-up device can assist constructors to finish setting-up of a steel arch and pavement of steel meshes, arch set-up operation efficiency is increased efficiency, and labor intensity of constructors is reduced.read more
