Abstract

The invention discloses a screw anchor drilling machine, comprising a drilling mechanism and a traveling part. The drilling mechanism and the traveling part are connected through a supporting mechanism. The traveling part comprises a crawler chassis, and the supporting mechanism is a tower lifting hydraulic cylinder which is used for lifting and arranging the drilling mechanism connected between the drilling mechanism and the traveling part. The low-speed and large-torque power head is used for the power head swing mechanism of the invention. The auxiliary functions of the mechanism mainly comprise the inclination angle adjusting of a frame and the fixing of a force application mechanism,, thereby being capable of disposing the counter force and the counter torque reasonably and ensuring the concentricity and the parallelism of the drilling of the screw anchor. The screw anchor drilling machine of the invention has good maneuverability, and is suitable for the field work with decentralized working location.

Description

technical field [0001] The invention relates to the field of electric construction machinery, in particular to a helical anchor drilling machine for iron tower foundations of transmission lines. Background technique [0002] Spiral anchor foundation is a new form of transmission line iron tower foundation, which has been widely used abroad. Spiral anchor foundation is especially suitable for geology with shallow groundwater. The screw anchor rod is rod-shaped, with a helical screw blade at the end, which is screwed into the soil layer by the transmission torque of the power head reducer. In the construction of transmission lines, when encountering sandy soil or shallow groundwater geology, the construction period will be affected due to the difficulty of excavating the foundation, and the use of spiral anchors can better solve this problem. Use hydraulic and mechanical power to drill the spiral anchor to the design depth, and then use the shear force between the spiral anch...
