The invention belongs to the technical field of crane equipment, and particularly relates to a hoisting mechanism of a portal crane, which comprises a rack, and a lifting mechanism and a traveling mechanism are arranged on the rack; the lifting mechanism comprises a pair of winding drums rotating along the rack, a lifting hook is arranged below the pair of winding drums, and supporting wheels are rotationally connected to the two sides of the lifting hook; steel wire ropes are arranged on the pair of supporting wheels in a penetrating mode, the two ends of each steel wire rope are wound on the pair of winding drums respectively, and a pair of lubricating mechanisms for lubricating the steel wire ropes on the pair of winding drums respectively are arranged on the machine frame. The lubricating mechanism comprises a lubricating box fixedly connected with the rack, and the lubricating box is connected with an outer lubricating structure and an inner lubricating structure which are used for lubricating the steel wire rope. The inner lubricating structure comprises a plurality of flowing grooves which are formed along the circumference of the winding drum and used for flowing of lubricating liquid, and discharging assemblies corresponding to the flowing grooves are arranged on the winding drum; the problem that a hoisting mechanism of an existing portal crane is inconvenient to lubricate is effectively solved.

    本发明属于起重机设备技术领域,具体涉及一种桥门式起重机的起升机构,包括机架,机架上设有提升机构、行走机构;所述提升机构包括一对沿机架转动的卷筒,一对所述卷筒下方设有吊钩,吊钩两侧均转动连接有支撑轮;一对所述支撑轮上均穿设有钢丝绳,钢丝绳的两端分别缠绕在一对所述卷筒上,机架上设有一对分别对一对所述卷筒上的钢丝绳进行润滑的润滑机构;所述润滑机构包括与机架固接的润滑箱,润滑箱上连接有对钢丝绳进行润滑的外润滑结构、内润滑结构;所述内润滑结构包括沿卷筒圆周设置的多个供润滑液流动的流动槽,卷筒上设有与流动槽对应的出料组件;本发明有效的解决了现有桥门式起重机的起升机构,不便进行润滑的问题。
