Description

Technical Field

[0001] The utility model relates to the technical field of drilling righting mechanisms, in particular to a drilling righting mechanism for engineering geological drilling. Background Art

[0002] Engineering geological drilling is a drilling activity carried out in soil, rock or other geological materials. Holes are drilled in rock formations and core samples are taken out to understand the geological conditions and obtain information on underground structure and composition to support engineering design, construction and geological research.

[0003] After searching, the drilling straightening mechanism for engineering geological drilling with announcement number CN218324777U includes a limit sleeve; a movable groove, which is opened at the center of the limit sleeve; a support component, which is arranged at the bottom of the limit sleeve; a limit bracket, which is evenly distributed in the movable groove in an annular shape; and an adjustment component, which is used to adjust the position of the limit bracket. The utility model effectively prevents the operator from straightening the drill rod again during each downward drilling operation to avoid the drill rod from breaking due to eccentric movement during drilling. The operation is simple and convenient, and it is convenient for continuous operation.

[0004] Based on the above patent, the setting of the movable groove and the adjusting component facilitates the up and down movement of the drill rod in the movable groove. The drill rod is straightened and limited by the action of the movable groove to ensure the stability of the drill rod when moving up and down and avoid displacement. At the same time, the meshing connection between the transmission gear and the gear ring facilitates the adjustment of the position of the limit bracket. However, the above technical means do not set a limiting means for the torsion plate. When the drill rod is in operation, a certain vibration will be generated, causing the limit sleeve to shake, which in turn affects the deflection of the torsion plate, causing the screw to rotate, and the limit bracket on the outer wall of the drill rod becomes loose, which will lose the straightening effect on the drill rod. Moreover, the installation and fixation of the limit sleeve only relies on the resistance force of the bolts. This method is simple, but it is easy to loosen, which will cause the misalignment of the limit sleeve. Utility Model Content
