Abstract

The invention discloses a large-aperture construction raise boring machine which comprises a propelling mechanism, a manipulator assembly, a host chassis, a regulating mechanism, a dynamic plugboard mechanism, a gearbox assembly, a top plate and a base, wherein the gearbox assembly is connected with the propelling mechanism; the two ends of the propelling mechanism are respectively connected with the top plate and the base; the base is respectively connected with the regulating mechanism, the host chassis and the manipulator assembly; the dynamic plugboard mechanism is arranged on the base. The large-aperture construction raise boring machine disclosed by the invention can construct under different geological conditions, is particularly suitable for hard rock geological conditions, can realize hard rock geological large-aperture boring and is high in degree of automation and working efficiency.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a large-diameter construction raise drilling machine, which has the ability to be applicable to various geological drilling, especially hard rock geological conditions, and has a high degree of automation and high work efficiency. Background technique [0002] As an important construction machine in mining machinery, raise drilling rig has been widely used in various shaft constructions in mine construction. It mainly uses the motor of the drilling rig to drive the hydraulic oil pump, and uses hydraulic power to transmit torque and thrust to the drilling tool. The system drives the drill pipe and drill bit to rotate. Under the action of thrust, the hob on the pilot hole bit or the reaming bit rolls and cuts the rock along the rock working surface at the bottom of the well to gradually form a wellbore. [0003] In underground construction, the raise drilling ...
