The invention discloses a port crane cargo boom rotating device. The port crane cargo boom rotating device comprises a base, fixing holes, a supporting base, an adjusting base, a sealing ring, a lowerbearing, an upper bearing, a side bearing, an oil injection device, a connecting base, fixing screws, a rotating base, installing holes and the like. The port crane cargo boom rotating device has theadvantages that the structure is reasonable and simple, the production cost is low, and installation is convenient; the arranged lower bearing can meet the requirement of the large bearing pressure of a crane and can meet the requirement of the large torque through cooperation with the upper bearing, and then the rotating stability and reliability are guaranteed; the arranged oil injection devicecan inject oil to a bearing in the rotating base, therefore, the resistance is reduced, and the long-time using effect is improved; and an internal hexagonal wrench rotary adjusting head can enable an oblique block to radially move to adjust the height of the adjusting base, therefore, the condition that the using reliability and stability are influenced due to the fact that a clearance exists between the upper bearing and the lower bearing is avoided, and great convenience is brought to later-period maintenance and adjustment.
本发明公开了一种港口起重机起重臂回转装置,包括底座、固定孔、支撑座、调节座、密封环、下轴承、上轴承、侧轴承、注油装置、连接座、固定螺钉、回转座和安装孔等;本发明具有结构合理简单、生产成本低、安装方便,这里设置的下轴承,能够满足了起重机较大承受压力的需要,而与上轴承相配合能够满足较大力矩的需要,从而确保了回转时候的稳定性和可靠性;本发明中设置的注油装置,能够给回转座内部的轴承进行注油,从而减少了阻力提高了长时间使用的效果;本发明中内六角扳手旋转调节头能够使斜块径向移动对调节座的高度进行调节,从而避免轴承上下之间存在间隙影响使用的可靠性和稳定性,另外也给后期维护调节带来了很大的便利。
