Modular mountain rig

Abstract

A modular mountain area down-the-hole drill rig comprises a vehicle frame beam module provided with a control module, vehicle frame longitudinal beam modules installed at both ends of the vehicle frame beam module, and a support leg module installed on the vehicle frame longitudinal beam module; a movable arm module is further arranged on the vehicle frame beam module, the movable arm module is provided with a front extension hydraulic cylinder, a front end of the front extension hydraulic cylinder is connected with a drill arm adjusting module, a front side of the drill arm adjusting module is connected with a propulsion beam of a drill arm module, a propulsion trolley module is arranged on a front side of the propulsion beam, a power head module is arranged on the propulsion trolley module, and the power head module is connected with a cluster hammer module through a drill rod. The large-diameter mountain area down-the-hole drill rig can be conveniently disassembled and assembled, the weight of each module is less than 200 kg, convenient transportation is achieved, and the drill rig is suitable for construction requirements of a large-diameter foundation pit in a mountain area. In addition, the movable arm module and the drill arm adjusting module can adjust a construction angle of the drill arm module, and the drill rig is suitable for a complex terrain in a mountain area.
