Description

Gradiograph with flexible rod and double plates

The utility model is to measuring the improvement of the instrument of hole deviation degree in the geological prospecting borehole.

Now the mining area of disturbing that is magnetic is carried out in the geological prospecting borehole; the degree of crook of promptly holing in the drift angle and the position angle of hole deviation is measured " the price fixing clinograph " that is adopted; being configured to of its tiltmeter: in the protection tube of tiltmeter; fixed mount is installed; the free rotating apical axis of the measurement bay that can make its mounted inside is housed on its fixed mount top, and the divided circle that is carved with 0～360 degree on every side of measuring the terminal point angle is equipped with at the top.Apical axis is equipped with in the measurement bay bottom, matches in fixed mount with the agate bearing of its fixed mount bottom.The drift angle index dial is equipped with at the measurement bay middle part, and the weight-adding hammer that works the effect of laying particular stress on that has vernier graduation is equipped with in the upper end of measurement bay.Brake disc is equipped with in the measurement bay bottom, its brake disc is to be controlled by the timing watch of its underpart, when timing watch is covered on schedule, brake disc will be by the direct jack-up of its starting handle, measurement bay and drift angle dish will be compressed and fix by rising, quick-access goes out instrument ， And reads measured boring from instrument drift angle and terminal point angle.Its price fixing tiltmeter is to be enclosed in the survey tube at the hard straight measuring staff two ends of steel to use.

Above-mentioned " price fixing clinograph " in use weigh owing to measuring staff is long, uses and carries all inconveniently, and more piece is unloaded, and catcher is continuous to bother.Long hard steel pole measuring tool and drilling axis is difficult for being consistent, and surveys the accuracy that the intersection error of surveying with ring will influence measurement result thereby produce ring.The terminal point angle dish of surveying the terminal point angle in the instrument only is one, need put into two tiltmeters simultaneously again in order to verify its accuracy.(not only the formality trouble is uneconomical again).For the shock attenuation device that tiltmeter in use there is no need again, instrument is subject to shake or impact and malfunctioning or cause the damage of instrument.Brake disc is jack-up by timing watch control and directly, and the damping force of this direct jack-up is less, and what tressel and drift angle dish were fixing is not very firm, and it is easily lax and lose accuracy to be shaken the back.

The utility model is in order to improve clinograph, to overcome the shortcoming and the problem of above-mentioned existence.

The utility model is performed such improved; below the agate bearing that links to each other with the measurement bay bottom, the terminal point corner bracket is installed; the index dial of its terminal point corner bracket is corresponding with the terminal point angle dish of measurement bay bottom; can verify the terminal point angle value that records in the use mutually; and between measurement bay and terminal point corner bracket, be equipped with alidade; be screwed in the protection tube; the foundation brakes that the following installation of terminal point corner bracket is made according to lever principle; it has improved damping force greatly; make it measurement bay and terminal point corner bracket and obtain comparatively firm fixing; under general shock conditions, will not be subjected to its interference and the lax accuracy that loses.Measuring staff is made flexible measuring staff by the steel wire circumvolution, be equipped with to carry flexibly and draw joint, directed catcher, tuning catcher and damping orientating device, it has the bending of being easy to and warp-wise can transmit characteristic than high pulling torque, can avoid being hit in the measuring process in instrument being sent into boring again and makes its damage malfunctioning.
