The invention provides a traction device for a standard knot introduction frame of a movable arm tower crane, and belongs to the technical field of movable arm tower crane jacking assistion.The traction device comprises an introduction guide rail, a first pulley yoke, a second pulley yoke, a traction rope and an introduction trolley, the introduction trolley is arranged on the introduction guide rail, and the lower portion of the introduction trolley is connected with a standard knot to be introduced; the first pulley yoke and the second pulley yoke are arranged above the leading-in guide rail, one end of the traction rope is connected with the leading-in trolley, the other end of the traction rope sequentially penetrates through the first pulley yoke and the second pulley yoke and is connected with an external tower crane lifting hook, and the traction rope is pulled upwards through the lifting performance of the external tower crane. And the introduction trolley drags a to-be-introduced standard knot to move through the traction rope and the introduction guide rail. The hoisting characteristic of the tower crane is utilized, the traction rope, the first pulley yoke and the second pulley are used for introducing the standard knot, manual traction is not needed, the standard knot can be introduced only by hanging the traction rope on the guide rail by one operator, and safety and high efficiency are achieved.
本发明提供一种动臂塔机标准节引进架的牵引装置,属于动臂塔式起重机顶升辅助技术领域,包括引进导轨、第一滑轮架、第二滑轮架、牵引绳和引进小车,引进小车设置在引进导轨上,引进小车的下方与待引进的标准节连接,第一滑轮架和第二滑轮架设置在引进导轨的上方,牵引绳的一端与引进小车连接,牵引绳的另一端依次穿入第一滑轮架和第二滑轮架并与外部塔机吊钩连接,利用外部塔机自身的起吊性能将牵引绳向上牵引,引进小车通过牵引绳和引进导轨牵引待引进的标准节移动。本发明利用塔机自身的起重特性,使用牵引绳、第一滑轮架和第二滑轮来引进标准节,无需人力牵引,只需一名操作人员在导轨处穿挂牵引绳即可完成标准节引进,安全且效率高。
