Detailed Description

As shown in fig. 1-2, a planetary rotary spreader of a metallurgical crane comprises a horizontally arranged rectangular upper hanging beam 1, a pair of pulley blocks 2 are symmetrically fixed at two ends of the upper hanging beam 1, and the pulley blocks 2 are positioned above the upper hanging beam 1. The top center department of going up hanging beam 1 is equipped with the reduction gear support frame, is fixed with the planetary reducer 3 of vertical setting on the reduction gear support frame, and the top of planetary reducer 3 is fixed with motor base, is equipped with the driving motor 4 of vertical setting on the motor base, driving motor 4 is connected with the controller of hoist through the wire. The motor base plays a role in supporting and fixing the driving motor 4. The transmission output shaft of the driving motor 4 is in transmission connection with the power input shaft of the planetary reducer 3 through a coupler. The center of the top end of the upper hanging beam 1 is provided with a through hole, a bearing is assembled in the through hole of the upper hanging beam 1, a rotating shaft 5 is arranged in the through hole, and the rotating shaft 5 is assembled in the bearing. The lower extreme of planetary reducer 3 is equipped with the shaft coupling, and the upper end of axis of rotation 5 is connected with planetary reducer 3's power take off end transmission through the shaft coupling, and the shaft coupling plays the connection fixed action. The lower end of the rotating shaft 5 extends to the lower part of the upper hanging beam 1, a rectangular lower hanging beam 7 is arranged below the upper hanging beam 1, and the top end of the lower hanging beam 7 is fixedly connected with the rotating shaft 5 through a flange 6. The lower hanging beam 7 is fixed with symmetrically arranged hanging lugs 8, the hanging lugs 8 are fixed at two ends of the lower hanging beam 7, and the hanging lugs 8 are arranged downwards.
