The invention discloses an anti-shake protection device for a lifting rope of a crane, which relates to the technical field of cranes, and comprises a crane electric hoist shell, a lifting shaft and a servo motor, a pair of movable pulleys are arranged on a hook frame, a pull rope penetrates through the fixed pulleys, and two ends of the pull rope respectively penetrate through the pair of movable pulleys reversely. According to the anti-shaking protection device for the lifting rope of the crane, the lifting shaft is used for winding the pull rope, the pull rope is wound from the two ends of the pair of movable pulleys, and the lifting rope is wound from the two ends of the movable pulleys; the movable pulley abuts against the fixed rod, so that the buffering protection effect is achieved, in the ascending process of the sliding rod, the piston is driven to move upwards, and under the pressure in the oil tank, the hook frame is prevented from swinging towards the winding end; lubricating oil reaches the bearing through the discharge pipe and the oil way and lubricates the bearing, and therefore normal work of the movable pulley is guaranteed.
本发明公开了一种起重机提升绳索防晃动保护装置,涉及起重机技术领域,包括起重机电葫芦壳体以及起重轴和伺服电机,挂钩架上设有一对动滑轮,拉绳穿过定滑轮,拉绳的两端分别反向穿过一对动滑轮,起重机电葫芦壳体的底端设有具有缓冲阻拦作用的固定杆,固定杆上安装有油箱,本发明一种起重机提升绳索防晃动保护装置,起重轴进行卷收拉绳,拉绳从一对动滑轮的两端进行卷收,避免一端进行卷收拉绳时挂钩架偏向卷收端进行摆动,从而起到防止摇晃的作用,动滑轮与固定杆抵触,从而起到缓冲防护的作用,滑动杆上升过程中,带动活塞向上运动,在油箱内部的压力下,润滑油通过排出管和油路到达轴承处并对其进行润滑,从而保证动滑轮的正常工作。
