Wall after mudcake continuously without starting to be lifted.When in lifting process close to mudcake section, winch switches to low speed to be lifted, motor anti-twisted first
Reversion, sliding cone is driven to move down by screw mechanism, sliding cone promotes anti-twisted contact during moving down, anti-twisted to touch
Head extrusion spring open laterally, when screw be displaced downwardly to bottom it is spacing when, anti-twisted contact close-contact rope coring drill pipe it is interior
Wall, lifting of winch power gradually rises until peak, shows that anti-twisted assembly is in open configuration, it is possible to provide anti-twisted power, closes anti-
Turn round motor.Cutting blade motor is then turned on, scraper overcomes magnet suction to open under the action of the centrifugal force, jagged cutting edge and rope
The inwall contact of heart drilling rod is asked for, continuous rotary cutting, realizes the purpose for clearing up mudcake, as shown in Figure 2.Drilling rod inwall mudcake is clear
After reason terminates, cutting blade motor is first shut off, scraper is being conducted oneself with dignity and is being in convergence state under suction；It is then turned on anti-twisted motor
Rotate forward, driven by screw mechanism mobile until upper limit, sliding cone is in up moving process, anti-twisted contact on sliding cone
Separated with rope coring drill pipe inwall, lifting of winch power is gradually decrease to normal value, anti-twisted when moving to upper limit on screw
For contact Complete Convergence in anti-twisted joint, scraper recovers off working state, completes mudcake prune job.
