Abstract
The invention discloses a multifunctional micropile drilling machine, comprising a base plate, a platform which is fixed on the base plate, a covering element and an amplitude variation mechanism which are arranged on the platform, and a drilling and lifting device which is connected with the amplitude variation mechanism, wherein a hydraulic system and a main control system are arranged in the covering element; the amplitude variation mechanism comprises a turning pair A and a turning pair B; the turning pair A drives the amplitude variation mechanism and the drilling and lifting device to rotate relatively to the platform by +/- 90 degrees; and the turning pair B drives the drilling and lifting device to rotate relatively to the amplitude variation mechanism by 360 degrees. The turning pair A of the multifunctional micropile drilling machine does not turn along with the platform and just drives the amplitude variation mechanism and the drilling and lifting device to turn, so that the turning moment is reduced and turning becomes quite steady; the turning pairs employed also are lower than the turning pair employed to drive the whole platform in power so that the cost is saved; the turning pair B is capable of rotating by 360 degrees; and in contrast with the similar drilling machine employing an oil cylinder for rotation, the multifunctional micropile drilling machine has the advantages that the rotation angle is large and positioning of drilling is also quite accurate.
