[0035] The supporting chassis 12 is the load-bearing chassis of the entire drilling rig.

[0036] During drilling operations, the mechanical power head 2 is positioned directly above the borehole opening, which is referred to as the borehole opening formed during drilling operations. When performing wireline coring operations, the support chassis 12 can be pushed by the first hydraulic cylinder to slide back and forth on the tracked chassis 11. In this embodiment, the maximum displacement is 500 mm, which ultimately allows the mechanical power head to move away from the borehole opening, facilitating tripping and tripping operations.

[0042] Specifically, the bottom of the mast 5 is hinged to the support chassis 12, and the mast 5 and the support chassis 12 are connected by the second hydraulic cylinder 9; the hydraulic transmission system 8 is connected to the second hydraulic cylinder 9 to realize the raising and lowering of the mast 5.
