The invention provides a pulling device. The pulling device comprises a support, an execution wheel, a transmission assembly and a driving assembly. The execution wheel is fixedly arranged on the transmission assembly, and the transmission assembly is rotationally connected with the support; and the driving assembly is fixedly connected with the transmission assembly. When the pulling device is applied to a chain block, a chain of the chain block on which a heavy object is hung can be attached to or fixed to a wheel groove of the execution wheel, then the driving assembly drives the executionwheel to rotate, the chain is wound around the execution wheel, and then the heavy object is lifted. The pulling device can rapidly pull the chain of the chain block to lift the heavy object, manual pulling of the chain is replaced, and the working efficiency is improved.
本发明实施例提供的一种拉动装置,包括支架、执行轮、传动组件和驱动组件;所述执行轮固定设置在所述传动组件上,所述传动组件与所述支架转动连接;所述驱动组件与所述传动组件固定连接。当拉动装置应用于手拉葫芦上时,可将悬挂有重物的手拉葫芦的链条与执行轮的轮槽贴合或固定,然后使驱动组件带动执行轮转动,来将链条缠绕在执行轮上,进而使重物被提起。本拉动装置可以快速拉动手拉葫芦的链条来提升重物,不仅替代人工拉动链条,而且提高了工作效率。
