Design of Boosting Type Clamp for Full Hydraulic Drive Underground Drill
Abstract:This paper introduces a boosting type cylinder clamp with symmetrical arrangement of force increasing device on both sides. The clamping force produced by cylinder acts on the drill rod based on lever boosting principle. This clamp has the advantages of small size and high clamping ability. The selection of the main design parameters and the calculation process are introduced in detail.
