Abstract

The invention discloses a rotary drilling rig power head comprising a power head. A fixed frame is fixed on the rear side of the power head; a fixed base is arranged outside the fixed frame; a mounting groove matched with the fixed frame is arranged in one side, close to the power head, of the fixed base; a fixed assembly connected with the fixed frame is arranged in the fixed base. A sliding plate is arranged on the rear side of the fixed base; a U-shaped base in sliding connection with the fixed base is fixed on the sliding plate; fixing plates are fixed on the top and the bottom of the U-shaped base correspondingly. A fixed disc is fixed on the rear side of the fixed base. A damping assembly fixed between the two fixed plates is arranged outside the fixed disc. The fixed assembly comprises a screw rod which is rotatably arranged between the upper side and the lower side of the fixed base, the upper end of the screw rod penetrates through the fixed base, the screw rod is externally sleeved with a threaded sleeve, and first L-shaped rods are fixed on the two sides of the top of the threaded sleeve correspondingly. The rotary drilling rig power head has the characteristics of convenient disassembling and assembling and stable working.

Description

technical field [0001] The invention relates to the technical field of a section power head, in particular to a power head of a rotary drilling rig. Background technique [0002] Rotary excavator is a comprehensive drilling rig, which has the characteristics of fast hole forming, less pollution and strong mobility. The short auger bit is used for dry excavation, and the rotary bit can also be used for wet excavation in the case of mud protection. When the rotary excavator is working, the drill rod is driven by the power head on it to perform drilling work. [0003] The power head of the existing rotary excavator is generally fixed by multiple bolts. When the power head is disassembled and maintained, it is necessary to remove multiple bolts, resulting in tedious and inconvenient disassembly work; at the same time, the vibration amplitude of the power head of the existing rotary excavator is Large, long-term work will cause great damage to itself, and at the same time lead ...
