Principle of work of the present utility model:
Hand push rod by anti-twisted test transmission shaft upper end applies torque to anti-twisted test transmission shaft and anti-twisted device, when applying moment of torsion hour, the anti-twisted moment that the bearing torque cutter of anti-twisted device and ice hole inwall effect produce with manually apply moment and balance each other; Increase the moment of torsion that applies, the moment that produces relative rotation between bearing torque cutter and ice hole inwall, its moment of torsion that applies is exactly the moment of torsion of the maximum that can bear corresponding to the anti-twisted device bearing torque cutter blade circumscribed circle diameter size under the temperature of ice hole and anti-twisted device under the ice hole dimension.Torque value is measured and by torque sensor, conversion and Adam's module physical signalling is converted to electric signal, transfers to computer and shows in real time data by configuration software.When carrying out tensile test, rotation drive feed screw nut by the inner leading screw of electric horizontal test board forms rectilinear motion with tautness meter, one end of stay cord links to each other with the hook of tautness meter front portion, and the other end of stay cord is connected with the draw ring that anti-twisted device bottom arranges.Draw anti-twisted device bottom draw ring by stay cord anti-twisted device is glided, anti-twisted device is under the traction of stay cord, and the value of thrust that instantaneous slip occurs shows numerical value by tautness meter, and this numerical value is exactly the resistance that whole drilling tool glides.When measuring simultaneously reactive torque that anti-twisted device bears and sliding force, in the rotary manual push rod, also draw anti-twisted device with stay cord and glide, the anti-twisted moment values that anti-twisted device produces and sliding force respectively on computer and tautness meter real time data show.When anti-twisted device bearing torque cutter blade circumscribed circle diameter tuned up, the anti-twisted moment that anti-twisted device bears increased, and slip resistance also increases under the corresponding drilling tool.Vice versa.
The beneficial effects of the utility model:
Can measure exactly drilling tool anti-twisted device in creeping into dark moral purity and subglacial basement rock process and bear slip resistance under anti-twisted moment and the drilling tool, having remedied in creeping into dark moral purity and subglacial basement rock process does not have to measure this blank of test platform that anti-twisted device bears slip resistance under anti-twisted moment and a whole set of drilling tool, can in time obtain the data of anti-twisted moment and sliding force, this platform provides accurately Data support for the ability of verifying anti-twisted device equalizing port subdrilling head generation moment of torsion.
