Description

Quick dismounting device of directional core drilling tool elbow joint Technical Field The invention relates to the technical field of disassembly of drilling tool bent joints, in particular to a rapid disassembly device for a directional coring drilling tool bent joint. Background In the fields of geological exploration, mineral exploration, scientific drilling and the like, a directional coring drilling technology is an important means for obtaining deep stratum core samples. The bent joint is used as a key component in the directional core drilling tool assembly and is used for connecting a drill rod and a hole bottom power drilling tool, and the directional deflection of a drilling track is realized through a specific bending angle of the bent joint, so that the deflecting requirements under different geological conditions are met. In the actual construction process, in order to adapt to the deflecting requirements of different strata or to replace wear parts, the bent joints with different bending angles need to be frequently disassembled and replaced. At present, in middle-size and small-size coring drilling construction, the disassembly of the elbow joint and the drilling tool joint mainly depends on manual operation. The common practice is that a plurality of workers cooperate, tools such as pipe tongs, stress application bars and the like are used for forcibly twisting the drilling tool joint, and when the threaded connection becomes abnormally fastened due to long-time bearing of pressure, torque and slurry erosion, even an iron hammer is needed to strike the drilling tool to loose the vibration. The traditional disassembling mode has the outstanding problems that firstly, labor intensity is high, disassembling efficiency is low, a large amount of manpower and working hours are consumed, construction progress is seriously affected, secondly, manual operation is difficult to accurately control force application direction and force, the drill rod is likely to slide down due to slight carelessness, tools rebound, personnel injury is easily caused, serious potential safety hazards exist, and moreover, a drilling tool thread and a bent joint body are easily damaged in a violent disassembling mode, the service life of equipment is shortened, and construction cost is increased.
