具体实施方式Detailed ways

如图1-3所示,一种用于输电线路检修的接地线装置,包括接地钩3和通过导线33连接在接地钩上的接地卡34。所述的接地钩3由板块弯折为顶端平直部分和下部弯钩两部分,呈近似的“C”型结构。接地钩顶端平直部分31与弯钩部分之间设有夹板7,夹板居中位置处固接有拉杆1,拉杆上端穿过接地钩顶端平直部分开设的拉杆孔,通过拉绳环与绝缘拉绳8连接,拉杆两边的夹板上分别固接有螺栓2,螺栓的上端穿过接地钩顶端平直部分开设的螺孔,由螺母固定。夹板与接地钩顶端平直部分之间的螺栓上套装有弹簧5。夹板前侧居中的部位连接有挂钩6,接地钩顶端平直部分前侧居中的部位开设有与挂钩配合的卡槽32;夹板与接地钩顶端平直部分之间的拉杆上内嵌有挂扣4。As shown in FIGS. 1-3 , a grounding wire device for power transmission line maintenance includes a grounding hook 3 and a grounding clip 34 connected to the grounding hook through a wire 33 . The grounding hook 3 is bent from a plate into two parts, a straight top part and a lower hook, which are in an approximate "C" shape. A splint 7 is arranged between the straight part 31 at the top of the grounding hook and the hook part, and a tie rod 1 is fixedly connected to the center of the splint. Rope 8 connects, and the clamping plate on pull bar both sides is fixedly connected with bolt 2 respectively, and the upper end of bolt passes the screw hole that grounding hook top straight part offers, is fixed by nut. A spring 5 is sleeved on the bolt between the splint and the straight part at the top of the grounding hook. The center part of the front side of the splint is connected with a hook 6, and the center part of the front side of the straight part of the top of the grounding hook is provided with a card slot 32 for matching with the hook; the pull rod between the splint and the straight part of the top of the grounding hook is embedded with a hook 4.

使用时,利用绝缘拉绳8拉动拉杆1,使夹板7上的挂钩6与接地钩顶端平直部分上的卡槽32咬合,将接地卡34固定在杆塔塔材上;然后下放绝缘拉绳,使接地钩3的弯钩部分从线路导线下方钩住导线,轻轻拉紧绝缘拉绳带动拉杆上升,使夹板上的挂钩脱离接地钩顶端平直部分上的卡槽,套装在接地钩顶端平直部分与夹板之间的螺栓2上的弹簧5,在舒张力的作用下,迅速弹压夹板下压,从而将线路导线包裹夹紧在夹板和接地钩的弯钩部分之间,实现防脱目的;作业完毕,拉动拉杆使挂扣4上升穿过拉杆孔后,放松拉杆使挂扣自动卡接在接地钩顶端平直部分的上端面上,从而使夹板放松并脱离线路导线,接地钩弯钩部分在重力的作用下,脱离线路导线,即可完成拆除接地线。When in use, use the insulating stay rope 8 to pull the pull rod 1, so that the hook 6 on the splint 7 is engaged with the draw-in groove 32 on the straight part of the grounding hook top, and the grounding card 34 is fixed on the pole tower material; then the insulating stay rope is lowered, Make the hook part of the grounding hook 3 hook the wire from the bottom of the line wire, gently tighten the insulating pull rope to drive the pull rod up, so that the hook on the splint is detached from the card slot on the straight part of the top of the grounding hook, and set it on the flat top of the grounding hook. The spring 5 on the bolt 2 between the straight part and the splint, under the action of the tension, quickly springs the splint and presses down, so that the line wire is wrapped and clamped between the splint and the hook part of the grounding hook, and the purpose of preventing it from falling off is achieved. After the operation is completed, pull the pull rod to make the buckle 4 rise through the hole of the pull rod, relax the pull rod so that the buckle is automatically clamped on the upper end surface of the straight part of the top of the ground hook, so that the splint is loosened and separated from the line wire, and the ground hook hook Under the action of gravity, part of the ground wire can be removed from the line wire to complete the removal.
