AI Technical Summary
Existing inclined shaft construction equipment suffers from low mechanization, transportation difficulties, poor functional applicability, and high construction costs. In particular, when the inclination of the inclined shaft is large, conventional equipment is difficult to meet the needs of multi-process mechanized operations.
Design a modular trolley frame that connects multiple modular frames with bolts to achieve a detachable and adjustable structure. Equipped with replaceable rock drilling and muck removal booms and support platforms, it can adapt to different working conditions.
It has improved the mechanization of inclined shaft construction, simplified equipment relocation and transportation, reduced construction costs, and enhanced the functionality, applicability, and flexibility of the equipment, making it suitable for different tunnel sizes and working conditions.
