The invention relates to the technical field of winches, in particular to a winch capable of preventing quick pay-off. According to the winch capable of preventing rapid paying off, centrifugal force braking is achieved, and safety is high. According to the technical scheme, the device comprises a first base and the like; the base I is internally and rotatably connected with a rotating shaft, the rotating shaft is fixedly connected with a bobbin, the device is characterized by further comprising a brake disc, a telescopic assembly, a rotating disc, a centrifugal block, a base II, a moving assembly, a hollow cylinder and a circular chuck, one end of the rotating shaft is fixedly connected with the brake disc, and the telescopic assembly is arranged on the brake disc. The winch has the beneficial effects that when the winch breaks down or is suddenly powered off, a worker cannot find the fault in time, under the action of gravity, goods can pull the steel wire rope to rapidly descend, the rotating speed of the bobbin is increased, and the higher the rotating speed is, the larger the centrifugal force is generated; and the centrifugal block drives the circular chuck to be meshed with the triangular groove in the brake disc for clamping and braking.

    本发明涉及卷扬机技术领域,具体为一种可防止快速放线的卷扬机。技术问题:提供离心力制动、安全性较高的可防止快速放线的卷扬机。技术方案如下:包括有底座一等;所述底座一内转动连接有转轴,所述转轴上固接有线筒,其特征在于,还包括有制动盘、伸缩组件、转动盘、离心块、底座二、移动组件、空心圆柱和圆形卡盘,所述转轴一端固接有制动盘,所述制动盘上设有伸缩组件。本发明的有益效果:卷扬机出现故障或突然停电时,工作人员未能及时发现,在重力的作用下,货物会拉动钢丝绳快速下降,线筒的转动速度加快,此时转速越快产生离心力越大,使离心快带动圆形卡盘与制动盘上的三角型凹槽啮合进行卡紧制动。
