Device for distributing bulk material with a distribution spout supported by a cardan suspension

摘要

A distribution device for distributing bulk material with a distribution spout on a cardan suspension that has a first and a second gimbal member pivotable about two perpendicular suspension axes where a drive arrangement has a first and a second transmission mechanism for controlling pivotal motion of the distribution spout about the suspension axes, and the drive arrangement has a further cardan joint, with a first part pivotable about a third axis and a second part pivotable about a fourth axis, and a rotary motor for driving a rotary drive shaft that is connected to the cardan joint by means of an articulated connecting arm such that the rotational position and the axial position of the drive shaft determine the pivotal position of the second part about the third and fourth axes respectively, where the transmission mechanisms transmit torque about the third and fourth axes from the cardan joint to the cardan suspension for pivoting the distribution spout about the first and second axes respectively.

主权项

1. A device for distributing bulk material in a metallurgical reactor, said device comprising
a distribution spout supported by a cardan suspension with a first gimbal member that is pivotable about a first axis and a second gimbal member that is pivotable about a second axis and supported by said first gimbal member; a drive arrangement with a first transmission mechanism connected to said cardan suspension and a second transmission mechanism connected to said cardan suspension for controlling pivotal motion of said distribution spout about said first axis and about said second axis; wherein said drive arrangement further comprises
a cardan joint with a first part that is pivotable about a third axis and a second part that is pivotable about a fourth axis and supported by said first part; anda rotary motor for driving a rotary drive shaft that is axially slideable and connected to said second part of said cardan joint by means of an articulated connecting arm so that a rotational position and an axial position of said drive shaft determine a pivotal position of said second part about said third and fourth axes respectively; wherein, said first transmission mechanism connecting said first part to said first gimbal member or said second part to said second gimbal member and said second transmission mechanism connecting said second part to said second gimbal member so that torque about said third and fourth axes respectively is transmitted from said cardan joint to said cardan suspension for pivoting said distribution spout about said first and second axes respectively.
