Mechanical top-drive drilling rig is a machine that mixes mud drilling rig and air drilling rig in one equipment (National invention patent: ZL201510479602. 4).It adopts MT or AMT manual automatic transmission, 10 grade forward gears, and 2 grade reverse gears.Forward and reserve switching is sensitive and convenient.Main drilling methods: conventional DTH hammer drilling, Non-core PDC bit or Tricone bit drilling.
1. The machine can choose MT or AMT as transmission with high reliablity and long service life.
2. Mechnical winch is kept, whose lifting speed is high so that it can deal with well accidents.
3.Transmission efficiency is doubled than hydraulic transmission, low power consumption, more efficient.
4.Multifunctional, both can used for water well drilling and core drilling.
CONSTRUCTION CASS
Rotary mud and DTH air drilling systems are the most common well drilling method in world. While mud rotary is widely used for soft and medium formation soil, which can avoid the collapse effectively; DTH system is usually employed for faster drilling on medium and hard soil including rocky formations.
