Soft soil area ultra-long pile rotary drilling rig guide mechanism

Abstract

The invention discloses a soft soil area ultra-long pile rotary drilling rig guide mechanism. The guide mechanism comprises a lower cylinder and an upper cylinder, the top end of the outer side of thelower cylinder and the bottom end of the outer side of the upper cylinder are fixedly sleeved with a flange plate and a second flange ring correspondingly, the flange plate is fixedly connected withthe bottom end of the second flange ring through a plurality of bolts, and a plurality of iron cones are fixedly arranged at the bottom end of the lower cylinder. Four inclined supporting rods are movably connected to the outer ring of the bottom end of the flange plate through hinge seats correspondingly, four bases are movably connected to the bottom ends of the four inclined supporting rods through hinge seats correspondingly, four first threaded rods are connected to the middles of the four bases in a threaded penetrating and inserting manner correspondingly, and four walking mechanisms are fixedly arranged at the bottom of the outer side of the lower cylinder correspondingly. The guide mechanism has the beneficial effects that the lower cylinder and the upper cylinder are matched to form the whole guide mechanism, the upper cylinder is installed on a drill rod, the lower cylinder can be detachably positioned, then the guide mechanism can be conveniently matched with a drilling tool for use, and more convenience is achieved.

Description

technical field [0001] The invention relates to a guiding mechanism of a rotary drilling rig, in particular to a guiding mechanism of an ultra-long pile rotary drilling rig in soft soil areas, and belongs to the technical field of mechanical engineering. Background technique [0002] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. Because of its high efficiency, less pollution, and many functions, the rotary drilling rig adheres to the concept of people-oriented and environmental protection while adapting to the current pursuit of high-speed economic development. Therefore, it has occupied the main force in the construction of cast-in-place concrete piles at home and abroad. The status of the model. In the prior art, the rotary drilling rig generally needs to use a guiding mechanism to ensure the accuracy of piling during use. [0003] The guide mechanism of the existing rotary drilling rig is generally...
