Description

Technical Field

[0001] The utility model relates to the field of rotary drilling machines, in particular to an electric rotary drilling machine for compaction detection at a construction site. Background Art

[0002] A rotary drilling rig is a large-diameter, deep-hole drilling machine. While there were previously several models of rotary drilling rigs, including crawler, guide rod, and short column models, these are now rarely seen due to low construction efficiency, limited drilling diameters, and shallow drilling depths. Currently, two types are most commonly seen on construction sites: an attached type modified from a crawler crane, and a fully hydraulic type, based on an imported, imported, excavator-like chassis. The verticality of the drill rod is adjusted through a trapezoidal linkage and hydraulic cylinders. Rotary drilling has become a predominant method for drilling large-diameter, deep holes. Ground preparation at construction sites typically requires compaction, and after compaction, the rotary drilling rig is used to drill holes in the compacted ground to test its compaction.

[0003] In the prior art, when a rotary drilling rig is used to drill the ground requiring compaction testing, the edge of the drilled hole is easily affected by the drilling process, causing damage to the shape of the hole edge, thereby affecting the accuracy of the ground compaction test.
