The invention belongs to the technical field of connecting pipe arms, and particularly relates to a six-degree-of-freedom connecting pipe arm. The six-degree-of-freedom connecting pipe arm comprises afirst universal hinge type bellow expansion joint, a second universal hinge type bellow expansion joint and a pull rod constraint type bellow expansion joint with a steering connector and a straight-through connector, one end of the first universal hinge type bellow expansion joint is connected with a device connector, the other end of the first universal hinge type bellow expansion joint is connected with the second universal hinge type bellow expansion joint through a straight pipe, the other end of the second universal hinge type bellow expansion joint is connected with the steering connector of the pull rod constraint type bellow expansion joint, the straight-through connector of the pull rod constraint type bellow expansion joint is connected with a bent-pipe-shaped adjusting pipe, and the other end of the bent-pipe-shaped adjusting pipe is connected with an outer pipe connector. The six-degree-of-freedom connecting pipe arm is suitable for energy transmission of pipelines with various calibers and various flows; the connecting arrangement structure is simple, six-degree-of-freedom flexible compensation can be achieved in a single-plane mode and in a double-plane mode, and on-site installation and positioning of the connecting pipe arm are easy; and the six-degree-of-freedom connecting pipe arm is tolerant to the displacement cycle fatigue of a device system and is more suitable for long-term continuous fluid conveying working condition scenes.

    本发明属于连接管臂技术领域,具体涉及一种六自由度连接管臂,包括第一万向铰链型波纹膨胀节、第二万向铰链型波纹膨胀节和一个带转向接口和直通接口的拉杆约束型波纹膨胀节,第一万向铰链型波纹膨胀节一端连接装置接口,另一端通过直管连接第二万向铰链型波纹膨胀节,第二万向铰链型波纹膨胀节的另一端连接拉杆约束型波纹膨胀节的转向接口,拉杆约束型波纹膨胀节的直通接口连接弯管形调整管,弯管形调整管的另一端连接外管接口。本发明适用于各种口径管路、各种流量的能源输送;连接布置结构简单,既能单平面又能双平面的实现六自由度柔性补偿,易于连接管臂的现场安装定位;对装置系统的位移循环疲劳耐受,更适宜长期持续的流体输送工况场景。
