Abstract

The invention discloses a rotary lifting appliance of an electromagnetic plate crane and relates to the electromagnetic plate crane. By the rotary lifting appliance, the problems of complex structure, unreasonable structure design and poor sealing performance of the existing rotary lifting appliance are solved. A cross beam connected with a driving mechanism of the rotary lifting appliance is arranged above an electromagnetic suspended beam. A motor drives a speed reducer. An internal spline of an output shaft of the speed reducer is matched with an external spline of a rotating shaft to drive the rotating shaft to rotate. A flange at the lower end of the rotating shaft is connected with a flange at the end part of the electromagnetic suspended beam through a bolt. Screw threads at the upper part of the rotating shaft are connected with a lifting hook nut. A thrust bearing is arranged between the lifting hook nut and a bearing support which is sleeved on the rotating shaft and is connected with the cross beam. The lower end of the bearing support is provided with a sealing flange and is matched with the rotating shaft. A positioning bearing is also arranged between the bearing support and the rotating shaft.

Description

technical field [0001] The invention relates to an electromagnetic disk crane, in particular to a rotating hanger of the electromagnetic disk crane. Background technique [0002] At present, the electromagnetic disk cranes used for hoisting or stacking finished steel materials use two lifting points to rotate the spreader to place the steel materials, or to rotate and place the steel materials by the rotating mechanism matched with the crane lifting mechanism. [0003] The driving mechanism of the rotating spreader of the existing electromagnetic disk crane mostly adopts the output long shaft of the reducer to drive the pinion to rotate, and the pinion and the large gear cooperate to drive the rotation of the electromagnetic hanging beam to realize the rotation of the spreader. This kind of rotary spreader has a complex structure, the gear meshing surface is exposed to the air, the lubrication is not good, and the gear wears quickly. Contents of the invention [0004] The...
