The invention relates to a power supply body tensioning device and a freight station yard mobile contact network. The power supply body tensioning device at least comprises a tension providing device, a power supply body, a portal and a hanging assembly. The suspension assembly can move left and right on the door frame to drive the power supply body to be in a working position or a non-working position. The suspension assembly can also move relative to the door frame in the extension direction of the railway or keep a moving trend relative to the door frame in the extension direction of the railway; the tension providing device is used for driving the suspension assembly to move relative to the door frame in the extending direction of the railway according to the tightness degree of the power supply body so that the power supply body can be in a tensioned state. The problems that in the prior art, due to insufficient tension of a contact line, loosening and sinking are caused, a pantograph of a freight train jacks up, and the safety distance is insufficient are solved. The risk that in the prior art, a loose contact line strikes a pantograph is avoided, the problem that the contact line swings left and right is solved, and safety guarantee is provided for lifting of the pantograph to take electricity.

    本发明涉及供电体张紧装置及货运站场移动接触网,至少包括拉力提供装置、供电体、门架和悬挂组件;所述悬挂组件能够在门架上左右移动带动所述供电体处于工作位或者处于非工作位;所述悬挂组件还能够在铁路的延伸方向上相对于所述门架移动或者在铁路的延伸方向上相对于所述门架保持有移动的趋势;所述拉力提供装置用于根据所述供电体的松紧程度带动所述悬挂组件在铁路的延伸方向上相对于所述门架移动使得所述供电体处于张紧状态。避免了现有技术由于接触线张力不够,松动下沉,货运列车受电弓上顶,安全距离不够的问题。避免了现有技术中松动的接触线打弓的风险,克服接触线左右摇摆的问题,为受电弓抬起取电提供了安全保障。
