Embodiment
Below in conjunction with embodiment, the utility model is further described.
Please refer to shown in Fig. 1, a kind of modified model G5 turriform overhead-groundwire lifter, it comprises lifting arm 1, nut 2, support 3 and rolling bearing 9, a through groove 11 is offered in the lower end of lifting arm 1, lifting arm 1 correspondence position of through groove 11 both sides all offers installing hole, and support 3 and rolling bearing 9 are all placed on lifting arm 1, and nut 2 is threaded with lifting arm 1, support 3 and rolling bearing 9 between nut 2 and through groove 11, and rolling bearing 9 comparatively support 3 closer to nut 2.Arrange rolling bearing 9, make in the process of rotating nut 2, the friction between the lower surface of nut 2 and support 3 upper surface changes rolling friction into by sliding friction, and frictional force reduces greatly, decreases personnel's physical demands while the useful life of extending bracket 3.
Support 3 is for adopting channel-section steel material, and its waist height * leg wide * waist is thick is the concave structure of 55mm*145mm*5mm, certainly, and the wide hanging point angle steel width that will be not less than on the upside of overhead ground wire support of the leg of support 3.Support 3 center arranges a circular hole, diameter 30mm, can pass for lifting arm 1.Lifting arm 1 take diameter as the whole rod iron of 28mm is main body.Lifting arm 1 one end is provided with external screw thread, the high 60mm of nut 2 of the steel material supporting with it, and lifting arm 1 and nut 2, by being threaded of matching, are converted into moving both vertically of lifting arm 1 by horizontally rotating of nut 2.Through groove 11 is for being arranged at the rectangular recess of the wide 21mm in lifting arm 1 other end end, lifting arm 1 position of these through groove 11 both sides offers symmetrical installing hole, wherein, the installing hole of side can be threaded, and supporting bolt can be screwed through this installing hole.
Please refer to shown in Fig. 2, the utility model arranges one and the matching used sleeve assembly of nut 2, sleeve assembly comprises sleeve member 10 and is fixedly connected on the rod member 12 of sleeve member 10 side, the inside of sleeve member 10 has a hollow slots matched with nut 2 external dimensions, the operation that the periphery hollow slots of sleeve member 10 being placed on nut 2 can screw nut 2 or unclamp, the structure of sleeve member 10 and rod member 12 is only used during normal use, local line load can adopt extension rod 13 to increase moment time excessive, reduces personnel's physical demands.Rod member 12 arranges a groove away from the end, one end of sleeve member 10, arranges one realize the grafting of extension rod 13 and rod member 12 with the projection of this groove match in one end of extension rod 13.Because sleeve member 10 and nut 2 are nested together, there will not be and adopt when nut 2 being screwed as instruments such as spanners because grasping the situation tightly not causing handle high-altitude to be dropped.
One end of the connection gold utensil 7 of overhead ground wire is installed on ground wire 6 (all referring to overhead ground wire) here, and the other end is installed on the overhead ground wire support 8 parallel with ground wire 6.The Renewal process connecting gold utensil 7 please refer to shown in Fig. 3.
1, support 3 is stuck on the hanging point angle steel of overhead ground wire support 8, lifting arm 1 is extended to ground wire 6 place with one end of through groove 11 through overhead ground wire support 8.
2, lifting arm 1 and ground wire 6 are fixed, for the ground wire that diameter is less, directly more through groove 11 is passed ground wire 6, then ground wire 6 is stuck in through groove 11 by screwing bolts 4, during screwing bolts 4, it is in the thick rubber sleeve 41 of a sheathed 1cm in the part in through groove 11, and ground wire 6 can be avoided directly to contact with bolt 4, reduces the damage because of the ground wire 6 caused that rubs.For the ground wire 6 that diameter is larger, when through groove 11 is not enough to through ground wire 6, coordinate by shackle 5, directly ground wire 6 is passed in shackle 5, and then shackle 5 is installed on installing hole.For the ease of connecting the replacing (dismounting) of gold utensil 7, modified model G5 turriform overhead-groundwire lifter can adopt two, lays respectively at the both sides connecting gold utensil 7.
3, by sleeve assembly tightening nut 2, lifting arm 1 drives ground wire 6 to promote, until when the load of ground wire 6 is all transferred on lifting arm 1, and then can loosen connection gold utensil, change it.
Above-listed detailed description is illustrating for the utility model possible embodiments, and this embodiment is also not used to limit the scope of the claims of the present utility model, does not allly depart from the equivalence that the utility model does and implements or change, and all should be contained in the scope of the claims of this case.
