Abstract
1,068,606. Shovel excavators. LENINGRADSKY FILIAL VSESOJUZNOGO NAUCHNOISSLEDOVATEJSKOGO INSTITUTA STROITELJNODOROZHNYKH MASHIN. May 27, 1964, No. 21881/64. Heading E1F. [Also in Divisions G3 and H2] The boom-slewing mechanism of a rotarybucket excavator is driven by an electric motor which is supplied by a generator having its field winding excited by a magnetic amplifier. Computers for controlling the magnetic amplifier are used to determine the desired slewing- speed and the extreme positions of slew, as well as providing signals for stopping and reversing the motor at said limiting positions. As shown, tachometer generator 10 is driven by motor 11 and its field winding is excited by rotary transformer 18 in accordance with the cosine of the angle of slew. The output of the tachometer generator is compared with a voltage representing the initial slewing-speed and the error voltage is applied through amplifier 22 to pilot motor 23 for adjusting transformer 24. This transformer is associated with ring demodulator 17 and magnetic amplifier 14 for controlling the excitation of generator 12. The maximum slewing-angles in either direction are calculated by means of a formula connecting various factors, these factors being respectively dependent upon the width of the working-face in relation to a fixed line of advance of the excavator, the length of the boom, the angular inclination of the material being excavated, the angle of elevation of the boom, and the eccentricity of rotation of the boom with regard to a fixed axis. When the actual angle of slew reaches the computed valve, a relay responds to stop the motor, the excavator then being moved ahead automatically, and the boom being swung in the reverse direction.
