The slewing mechanism of the gantry crane comprises a slewing mechanism body, the slewing mechanism body comprises an outer cylinder part and an inner column part, the inner column part is rotatably connected to the interior of the outer cylinder part, a lubricating box is detachably connected to the exterior of the outer cylinder part, and a cover plate is arranged at the top of the lubricating box through a jacking assembly; the lubricating box is provided with an extrusion assembly and connected with the inner column piece, the bottom of the lubricating box communicates with an upper oil pipe, and an oil return pipe penetrates through the cover plate. The bearing part in the slewing mechanism can be lubricated so as to prevent the friction force of the bearing from being increased after long-time use to influence normal rotation, the slewing mechanism is driven in the lubricating process through rotation of the slewing mechanism, lubricating oil is dropwise added to the position of the bearing, and therefore extra power is not needed, and the service life of the slewing mechanism is prolonged. In addition, redundant lubricating oil is accumulated at the inner bottom of the outer column casing and flows back into the lubricating box through the oil return pipe, and therefore waste cannot be caused.

    本发明公开了门座起重机回转机构,包括回转机构,所述回转机构包括外筒件与内柱件,所述内柱件转动连接在外筒件内部,所述外筒件外部可拆卸连接有润滑箱,且润滑箱顶部通过顶压组件设有盖板,所述润滑箱上设有挤压组件并与内柱件连接,且所述润滑箱底部连通有上油管,所述盖板上贯穿有回油管。本发明中能对回转机构中的轴承部分进行润滑,以防止在长时间的使用后轴承的摩擦力增加而影响正常转动,在润滑过程中通过回转机构本身为的转动来驱动,并将润滑油滴加到轴承位置,这样无需额外动力,即可完成向轴承滴加润滑油的操作,另外多余的润滑油积聚在外柱筒内底部,并通过回油管回流到润滑箱中,这样也不会造成浪费。
