INSTALLATION INDICATING THE EXCAVATION LEVEL AND THE CONVEYING SLOPE

摘要

The invention relates to an installation indicating the excavation level and the conveying slope, especially designed for bucket-wheel excavators used in surface mining industry. The claimed indicating installation comprises a driving assembly (A) suitably mounted on the excavator arm and electrically connected to a measuring assembly (B) located inside the control cabin of the excavator. The driving assembly (A) comprises a gravitational pendulum (1) which, by means of a mechanical angular amplifier (2), engages a rotor (3) of a transmitting transducer (4) of the selsyn type. A system of voltages generated by the transmitting transducer (4) is sent farther through some conductors (6) to the measuring assembly (B), namely to a receiving transducer (7), the rotor (10) thereof being integral with a pointer (11) located in front of a calibrated dial (9).
