The invention provides a standard knot device and a tower crane, the standard knot device comprises a main chord member body, a male joint, a female joint and a pin shaft body, the male joint is arranged at the first end of the main chord member body, the male joint is provided with a first plug pin hole which is through in the radial direction, the female joint is a hollow circular pipe and is connected with the second end of the main chord member body, and the pin shaft body is arranged in the first plug pin hole; the outer diameter of the female joint is equal to the outer diameter of the main chord member body, the inner diameter of the female joint is smaller than the inner diameter of the main chord member body, a second bolt hole is formed in the female joint in a radial penetrating mode, and the female joint is arranged on the male joint of another adjacent standard knot device in a sleeving mode; the pin shaft body is used for being arranged in the first plug pin hole and the second plug pin hole in a penetrating mode to connect the two adjacent standard knot devices, a reinforcing plate on the outer side of the female connector is omitted, the problem that the manufacturing process of the reinforcing plate is complex is fundamentally solved, arrangement of idler wheels of a climbing frame is not limited, and therefore design of a climbing system is facilitated.

    本发明提供一种标准节装置及塔式起重机,标准节装置包括主弦杆本体、公接头、母接头和销轴体,公接头设置在主弦杆本体的第一端,公接头上开设有径向贯通的第一插销孔,母接头设置为空心圆管并与主弦杆本体的第二端连接,母接头的外径与主弦杆本体的外径相等,母接头的内径小于主弦杆本体的内径,母接头上径向贯穿地开设有第二插销孔,母接头套设于相邻设置的另一个标准节装置的公接头上,销轴体用于穿设于第一插销孔和第二插销孔内以连接相邻设置的两个标准节装置,取消了母接头外侧的加强板,从根本上上解决了加强板制作工艺复杂的问题,并且也不会对爬升架的滚轮的布置产生限制,从而有利于爬升系统的设计。
