Abstract
Provided is a drilling machine slewing clamping device. The drilling machine slewing clamping device comprises a main shaft, a deep groove ball bearing, a terminal pad, a adapter sleeve, a shaft gear, an oil cylinder body, a piston, slips, a semi-ring, a spring ring, a guide plate, slip seats, a saucer-shaped spring, a spacer sleeve, a driven gear and a gearbox body. Effective gear transmission is adopted to slew a drill pipe. The drill pipe is clamped by using the saucer-shaped spring to push the slip seats. The three slips which are evenly distributed along a circumference are enabled to move towards the center and clamp the drill pipe to deliver torsion. Clamping force is constant and is not affected by corotation and inversion. The drilling machine slewing clamping device has the advantages of being simple in structure, light in weight, convenient to assemble and disassemble, high in efficiency, applicable to drill pipe slewing clamping of various high-power drilling machines under the shaft and wide in popularization prospect.
