The invention discloses a hoisting structure and a crane. The hoisting structure comprises a hoisting rod, a rotating shaft and a chain, wherein the lifting rod comprises a lifting end and a fixing end, the rotating shaft is arranged at the lifting end of the lifting rod, and a first gear is arranged on the periphery of the rotating shaft. In the extending direction of the chain, the chain sequentially comprises a first chain body, a meshing chain body and a second chain body. The meshing chain is meshed with a first gear on the rotating shaft, the first chain is located on one side of the rotating shaft, the second chain is located on the other side of the rotating shaft, and the first chain and the second chain move in opposite directions along with rotation of the rotating shaft. The problems that in the prior art, when a crane lifts a section of steel wire rope, the crane needs to be operated twice, the steel wire rope lifted to a lifting well opening needs to be fixed before a lifting hook is lowered every time, and operation is tedious are solved, meanwhile, the movement amount of the lifting rod is small, a large number of shielding objects do not need to be transferred, and operation is convenient.
本发明公开了一种吊装结构及吊机,其中吊装结构包括吊杆、转动轴以及链条。其中,吊杆包括吊装端及固定端,转动轴设置于吊杆的吊装端,转动轴的外围设置有第一齿轮。沿链条的延伸方向上,链条依次包括第一链条、啮合链条以及第二链条。啮合链条与转动轴上的第一齿轮相啮合,第一链条位于转动轴的一侧,第二链条位于转动轴的另一侧,第一链条与第二链条随着转动轴的转动沿相反的方向运动。本发明解决了现有技术中在吊机吊一段钢丝绳时,需要操作两次吊机,每次将吊钩降下来之前,需要先固定吊至吊井口的钢丝绳,操作比较繁琐的问题,同时,采用本发明吊杆的移动量较小,不必大量转移遮挡物,操作比较方便。
