Abstract

The invention discloses a large-caliber rotary jetting drill pipe clamping device, which includes a supporting mechanism, a clamping mechanism and an alignment mechanism. The supporting mechanism includes a square supporting frame and a supporting column vertically arranged on the front part of the supporting frame, the alignment mechanism includes an X-axis alignment mechanism and a Y-axis alignment mechanism, the X-axis alignment mechanism is arranged on the front part of the supporting frame, the supporting column is fixed on the front part of the X-axis alignment mechanism, the X-axis alignment mechanism is connected with the supporting frame and the supporting column, the supporting column can slide along the X-axis alignment mechanism, the clamping mechanism is arranged on the frontpart of the supporting column, and the Y-axis alignment mechanism is arranged on the lower part of the square supporting frame. According to the large-caliber rotary jetting drill pipe clamping device, a drill pipe is clamped, slips are conveniently replaced, drill pipes with different diameters are conveniently clamped, the drill pipe is fine-adjusted, the drill pipe is kept in the vertical position at all times, inclination of the drill pipe due to vibration in the working process is avoided, and the quality of cement piles is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a clamping device for a large-diameter rotary spray drill pipe. Background technique [0002] At present, the clamping method of large-diameter drill pipes used in domestic engineering drilling rigs is double cylinder clamping, and the coaxial center line is directly aligned with the top. This method has a relatively simple structure and a direct working process. It is easy to cause wear of slips and drill pipes, and slips cannot be freely replaced according to the diameter of the drill pipe, which also increases labor and time costs in the construction process; and once the existing large-diameter drill pipe clamping device clamps the drill pipe , there is the defect that the position of the drill pipe cannot be adjusted, and the existing large-diameter drill pipe clamping device is prone to inclination due to vibration during the working process of the drill pipe...
