The invention discloses an anti-pull-back mechanism and a mobile power transmission line crossing stringing vehicle, and belongs to the technical field of crossing frames. An anti-pull-back mechanism and a mobile power transmission line crossing stringing vehicle are disclosed, the anti-pull-back mechanism comprises an anti-pull-back mechanism body, the anti-pull-back mechanism body comprises a penetrating ring, the penetrating ring is provided with a through cavity for a bearing cable or a circulating rope to penetrate through, and a plurality of one-way limiting assemblies are slidably arranged at the through cavity at equal intervals; the multiple one-way limiting assemblies jointly limit the bearing rope or the circulating rope. The one-way limiting assembly comprises an adjusting piece, and the end, located in the through cavity, of the adjusting piece is rotationally provided with a pressing roller. Through the arrangement of the multiple one-way limiting assemblies, the bearing rope or the circulating rope can be rolled in a one-way mode or limited according to requirements, and the problem that certain potential safety hazards exist due to the fact that the existing paying-off construction height is large, and the bearing rope or the circulating rope is pulled downwards due to the dead weight is solved.
本发明公开了一种防回拉机构及移动式输电线路跨越架线车,属于跨越架技术领域。一种防回拉机构及移动式输电线路跨越架线车,包括防回拉机构本体,防回拉机构本体包括穿设环,穿设环具有供承载索或循环绳穿设的贯通腔,贯通腔处可滑动地等距设有多个单向限位组件,所述多个单向限位组件共同对承载索或循环绳形成限位;单向限位组件包括调节件,调节件位于贯通腔内的一端可转动地设有压紧辊。通过多个单向限位组件的设置,可根据需求对于承载索或循环绳进行单向滚动或者对承载索或循环绳形成限位,避免了现有放线施工高度较高,承载索或循环绳因自重向下拉拽,导致存在一定的安全隐患的问题。
