The invention discloses a hoisting device of a portal crane, and relates to the technical field of portal cranes. A sliding rail groove is formed in the cross beam; the interior of the sliding rail groove is slidably connected with a machine body; the bottom end of the machine body is fixedly connected with a steel wire rope; the bottom end of the steel wire rope is fixedly connected with a lifting hook; an oil pump is fixedly connected into the machine body; the machine body slides on the cross beam so that the steel wire rope can move, the lifting hook can move through movement of the steel wire rope, objects needing to be lifted can be lifted, lubricating oil maintenance needs to be conducted on the cross beam and the machine body regularly, and lubricating oil is stored in the machine body and conveyed into the conveying pipe through the oil pump; lubricating oil is sprayed to the sliding rail groove from the spray head through the conveying pipe, the machine body slides on the sliding rail groove, the lubricating oil sprayed through the spray head can be maintained, a worker does not need to climb to maintain the lubricating oil, the lubricating oil maintenance work on the cross beam and the machine body is improved, and the danger of climbing of the worker is reduced.

    本发明公开了一种门式起重机的吊装装置,涉及门式起重机技术领域,包括横梁;所述横梁的内部开设有滑轨槽;所述滑轨槽的内部滑动连接有机体;所述机体的底端固接有钢丝绳;所述钢丝绳的底端固接有吊钩;所述机体的内部固接有油泵;通过机体在横梁上滑动从而使钢丝绳移动,钢丝绳的移动进而使吊钩移动,可以对需要吊运的物品进行吊运,需要定期给横梁、机体进行润滑油维护,机体的内部存储有润滑油,润滑油通过油泵输送至输送管内,润滑油通过输送管从喷头喷射至滑轨槽上,机体在滑轨槽上滑动,通过喷头喷射的润滑油可以进行维护操作,不需要工作人员登高进行润滑油维护,提高对横梁、机体的润滑油维护工作,也减少工作人员登高的危险性。
