Description

BE feeding and rotating integrated mechanism for novel chain bucket ship unloader

Technical Field

The utility model relates to a BE feed gyration integrative mechanism, especially a novel BE feed gyration integrative mechanism for chain bucket ship unloader belongs to the ship unloader field.

Background

The disc feeder and the BE slewing mechanism are important mechanisms of the bucket ship unloader. All the rotating parts of the BE part are fixed on the L-shaped steel structure through rotating supports. The disc feeder has the functions of receiving materials lifted by the chain bucket, conveying the materials to the discharge opening through the rotation of the disc feeder, and then unloading the materials to the arm support belt conveyor through the discharge hopper and the guide chute.

As shown in fig. 4, a conventional disc feeder is supported by 8 sets of support wheels and 6 sets of horizontal wheels are positioned. The rotation axis of the disc feeder should coincide with the BE rotation axis. The disadvantages of this disc feeder are:

1) 8 groups of supporting wheels are statically indeterminate. The 8 groups of supporting wheels have installation and adjustment errors, the top surfaces of the supporting wheels cannot be accurately adjusted to the same horizontal plane, and no structural measures for ensuring the equal heights of the supporting wheels are provided in design. Therefore, the top surfaces of the 8 groups of supporting wheels can only be partially contacted with the supporting tracks and are contacted and dynamically changed in operation alternately.

2) 6 groups of horizontal wheels of the disc feeder are arranged on the BE rotary cylinder body and rotate around the BE rotary support. And the track is arranged on the disc feeder and has a coaxiality error with the axis of the BE rotary support. When the disc feeder is installed and adjusted, a reasonable gap must be reserved between the horizontal rail and the horizontal wheel of the disc feeder to ensure the rotation. The rotating feeder is unstable in operation due to the existence of gaps and coaxiality errors, and the generated vibration has adverse effects on the working performance of the whole machine.

3) The supporting wheel is arranged at the bottom, the horizontal wheel is arranged inside, and the installation and adjustment are limited by space. The difficulty of adjustment is big, maintenance and change are difficult, and lubricated point is many and dispersed, and maintenance is difficult, the pipeline is too many.
