Abstract

The invention discloses a rare earth permanent magnet direct drive drilling machine. The drilling machine comprises a back-up wrench, wherein an NC protection connector is movably arranged on the inner side of the back-up wrench. The drilling machine adopts a top drive mode and has the advantages of being long in stroke, high in efficiency, high in reliability and the like; the drilling machine adopts a permanent magnet motor direct driving scheme, has no reduction gearbox, controls the rotating speed of the drilling machine through a frequency converter, and has the advantages of low noise, compact structure, simple control algorithm and the like; the drilling machine can carry out three-joint drilling, the efficiency is much higher than that of single-joint drilling, the lifting capacityis high, pump starting for hole bottom cleaning is carried out at any time, and drilling accidents are very convenient to handle; a winch of the drilling machine can achieve automatic bit feeding, hovering and friction-free braking, and the working conditions that a brake strap, a hub and a disc brake working clamp of a traditional drilling machine control the drilling down and bit feeding speedthrough friction force are replaced; and an intelligent driller console of the drilling machine has the functions of drilling machine operation and drilling parameter real-time display, electro-hydraulic system operation monitoring and display, fault display and alarm, and the automation, intelligence and integration levels in the drilling process are improved.

Description

technical field [0001] The invention relates to the field of direct drive drilling, in particular to a rare earth permanent magnet direct drive drilling rig. Background technique [0002] At present, there are generally three kinds of problems in my country's deep well drilling rigs: one is weak capability, the other is single function, and the third is complex structure; [0003] With the increase of oil, natural gas, shale gas, coalbed methane, geothermal, various mineral development deep wells, directional wells, and docking wells, there is an urgent need for a drilling rig with high efficiency, multi-function, large capacity, simple structure, and easy maintenance. To deal with the drilling problems of deep holes and complex formations; [0004] The existing vertical shaft drilling rig has a short stroke, and the hydraulic drilling rig has low energy efficiency and poor reliability. It is necessary to develop a drilling rig type with a long stroke, high energy efficienc...
