Testing platform for anti-torque device of deep ice center and under-ice base rock power-driven mechanical drilling tool

Abstract

The invention discloses a testing platform for an anti-torque device of a deep ice center and under-ice base rock power-driven mechanical drilling tool, which is formed by a frame, a torque sensor, an anti-torque testing drive shaft, an anti-torque device, an ice center drum, an ice center drum support, a tension meter, a temperature sensor and a power-driven horizontal testing platform, wherein the torque sensor is arranged at the upper part of a frame upright and is connected with the upper end of the anti-torque testing drive shaft at the lower part, the anti-torque device is inserted into an ice hole of the ice center drum fixedly arranged on the ice center drum support, and the ice center drum support is fixedly arranged on the bottom of the frame. The testing platform for the anti-torque device of the deep ice center and under-ice base rock power-driven mechanical drilling tool has the beneficial effects of being capable of accurately measuring the anti-torque moment born by the anti-torque device and the downward sliding resistance of the drilling tool in the drilling progress into the ice center and the under-ice base rock, thus providing accurate data support for verifying the torque generating capacity of a balance hole bottom drill bit of the anti-torque device.

Description

technical field [0001] The patent of the present invention relates to a test platform for anti-torsion devices of electromechanical drilling tools, in particular to a test platform for anti-torque devices of electromechanical drilling tools for deep ice cores and bedrock under ice. Background technique [0002] At present, in the field of drilling, armored cable-type electromechanical core drilling tools are widely used in polar ice drilling. The anti-torque device in the drilling tool plays a role in When drilling under the bedrock, the anti-torque device should be able to balance the torque generated by the drill bit cutting the bedrock under the ice. Once the anti-twist device fails, not only cannot ensure effective drilling, but also may cause the armored cable to kink or even break with the rotation of the drilling tool. However, there is no test platform that can measure the anti-torque torque and the sliding resistance of the drilling tool when the drilling tool dril...

Once the anti-twist device fails, not only cannot ensure effective drilling, but also may cause the armored cable to kink or even break with the rotation of the drilling tool

However, there is no test platform that can measure the anti-torque torque and the sliding resistance of the drilling tool when the drilling tool drills into the deep ice core and sub-ice bedrock.
