DEVICE FOR MOVING GEOPHYSICAL INSTRUMENTS IN RAISING BORE-HOLES Russian patent published in 1998 - IPC

Abstract RU 2124110 C1

FIELD: mining industry. SUBSTANCE: this relates to devices which are used in bore-holes drilled from dome part of mine shafts. Device has movable platform. Installed on movable platform is holder made in the form of multiple-face drum which ensures single-row laying of multiple-link system made up of rods and head-pieces of appropriately designed length. Accommodated inside rods of entire multiple-link system is continuous cable provided with supporting sleeves which prevent displacement of cable under its own weight. Head-pieces are made in the form of single-axle pivoted joints with detentes which prevent turning of links relative to longitudinal axis and also prevent changing of their total length when being laid in holder at introduction into bore-hole. Head-pieces are provided with protrusions and mating recesses for additional fixing of joint and prevention of turning links relative to longitudinal axis. Mast is installed on axle for possible angular displacement. Mast is provided with locks and additional movable supporting guiding pipe union which can be displaced along mast until coming in contact with wall of bore-hole at bore-hole mouth, and with detent. Power-actuated pushing driver is provided. Aforesaid embodiment of device prevents rotation of links relative to each other, allows for angular displacement of links at their laying in holder together with retaining unchanged length of links of entire multiple-link system. Cable which is located inside multiple-link feeding system ensures transmission of information from geophysical instrument to computer. Application of aforesaid embodiment of device ensures properly oriented introduction of geophysical instruments into raising bore-hole, and this advantage is combined with high accuracy of measurements, simplified design and improved reliability. EFFECT: higher efficiency. 3 cl, 8 dwg
