Auto-indicative deviation pendulum is intended for determining positions both vertically (roughly 50 degree ) and horizontally (360 degree ) in drilling for oil, and in other rock drilling, in directing a parabolic antenna and in indicating directions for industrial robots etc. The pendulum 1 is mounted 5a, 5b on the shaft 4 in such a manner that it can move freely in all directions. Its extended shaft 4 is bent at the top and this bent part indicates the vertical deviation by providing impulses to the turning arm 7, the sensing contacts 10 of which - mechanical, optical or magnetic - are fitted in the fork- shaped slit 6 of the pendulum shaft 4. The impulses provided are guided via lines in the horizontal-position cylinder 8 axis 9 to a plate 15. The plate has a limited number of concentric conductor rails, from which the impulses are guided via trailing contacts 16 - mechanical, optical or magnetic - to data transmission 20, 21. The plate 15 with trailing contacts 16 can advantageously be exchanged for the necessary number of parallel-mounted conducting rails on the inner wall of the detector cylinder 8, but insulated therefrom. The detector cylinder 8 has a vertical trailing contact 14 - mechanical, optical or magnetic - which senses the contacts which are located around the entire 360 degree on the inside of the box 2. The signals go via lines directly to data transmission 19, 21. In the manner described, vertical position deviation is obtained within roughly 50 degree and horizontal position indication within 360 degree. However the pendulum moves - irrespective of position - the detector cylinder always follows and gives only one degree value. <IMAGE> |
