Description

A new structure for slip ring installation

technical field

The utility model relates to the technical field of construction machinery, in particular to a novel structure for installing a collector ring.

Background technique

The collector ring is one of the important electrical components of the tower crane. Its function is to solve the problem of the main cable rotating under force when the slewing assembly is rotating. The function in the tower crane is like the brush in the motor. When the tower crane rotates, due to the existence of the collector ring, the rotating part drives the rotor of the collector ring to rotate around the stator, avoiding the rotation force of the main cable. In the slewing assembly, the internal structure space is limited, and the installation structure of the collector ring directly affects the passage of personnel and the maintenance convenience of the slewing support. This requires that the installation structure of the collector ring should not be too large to facilitate the passage of personnel and maintenance of equipment.

At present, during the operation of the tower crane, the upper support drives the rotor on the collector ring to rotate through the transmission lever. At this time, the transmission lever makes a circular motion, which requires a large space. The frame is arranged on the upper part of the lower support, and the relative position is relatively high, which is not conducive to the passage of personnel and affects the maintenance of the staff on the slewing bearing. When the tower crane stops working, the transmission lever stays on the top of the reversing door at this time, and the staff passes through the ladder and passes through the reversing door, just in time to touch the transmission lever, which affects the passage of the staff.
