HOLE MAKING ROBOT AND TRANSPORTING MECHANISM OF HOLE MAKING ROBOT Russian patent published in 1995 - IPC

FIELD: mining and construction; applicable in making horizontal and slightly inclined cased slim holes with complicated trajectory. SUBSTANCE: hole making robot has drilling head with working member 2. Slip forms is made flexible in transverse direction. It is attached to front section 6 of drilling head in a spaced relation to provide for running fit. Secured to rear section 7 of drilling head are supporting members 45 and 46. Feeder is made in form of a set of traction chassis 94 with drives. Drilling cuttings line is made in form of flexible hose and communicated with inner cylinder of section 6. Forms 3 is made in form of two coaxially installed cylinders interconnected by means of their nose part. Formed between cylinders is formation chamber. When robot is moved by feeding mechanism, working member outs hole bottom and broken ground is transported through cuttings line and flexible hose to surface. Components of cementing material are fed through recesses of forms nose part to get into formation chamber. They are mixed in the formation chamber and fed by forms cylinders 3. After setting of cementing material, strong casing of hole is formed. EFFECT: extended field of application with simultaneous increase of maintainability and reliability of work. 13 cl, 36 dwg
