<p>The present invention relates to a drive shaft support structure for a dredging head of a new structure capable of withstanding a high axial load applied in a longitudinal direction of a drive shaft. According to the present invention, the drive shaft support structure for a dredging head comprises: bearings (41, 42) to support a drive shaft (20) including a first bearing (41) to support an axial load of the drive shaft (20); and a second bearing (42) to support the load in a direction perpendicular to the axial direction of the drive shaft (20). The present invention has an advantage of effectively supporting axial load generated by the own weight of the drive shaft (20) due to the second bearing (42) when erecting a dredging pipe (10), and preventing bearings (41, 42) from being damaged by the load applied in the axial direction of the drive shaft (20).</p> |
