Embodiment
As shown in Figure 1, Figure 2 and Figure 4, the heavy electric power cable high-altitude of shown lifting formula is handed over across unfolding device, comprise the angle pulley 2 being connected on electric power tower 1, and be connected to carry on cable 3 between electric power tower multiple and walk line mechanism 4 in the air, described angle pulley 2 level is arranged in rectangular frame 21, and described rectangular frame 21 upper end is provided with the suspension ring 22 connecting electric power tower insulator 5.When heavy electric power cable is made up of three separate conductors, each line mechanism of walking in the air comprises four lifting wheels 41, when heavy electric power cable is made up of four separate conductors, each line mechanism of walking in the air comprises five lifting wheels 41, when heavy electric power cable has more than twice or twice, the quantity of lifting wheels 41 is that the total quantity of separate conductors adds one again; One of them lifting wheels 41 is connected to carrying cable 3 as running part, and all the other lifting wheels 41 are connected to running part respectively by the lifting rope 42 of increasing lengths.The adjacent lifting wheels 41 of each height are connected to corresponding pull rope 6.
As shown in Figure 3, each lifting wheels 41 comprise two cabling wheels 411 be arranged on respectively in a frame support 412, and support 412 openend of described two cablings wheel 411 is relative, and side is rotationally connected by hinge 413, and opposite side is located by connecting by latch 414; Metal anti-fall off chain 415 other end that pin rod and one end of described latch 414 are fixed on cabling wheel support is fixedly connected with, the described pin rod other end is also provided with Withdrawing pin, when pushing pin is vertical with pin rod, pin rod is positioned in guide and makes load-bearing axle, when pushing pin is parallel with pin rod, pin rod can be extracted out, thus lifting wheels 41 are opened formation introducing port; Support 412 cross bar of wherein cabling wheel is rotatably connected to high duty metal lifting ring 416, and the multiple spot on lifting rope 42 two ends and pull rope 6 is processed with fake respectively and connects lifting ring 416.
During construction the wire of heavy electric power cable and pull rope 6 by tractive effort effect in the state of raising up, each lifting wheels 41 adopt two cabling wheels 411, can prevent from directly contacting between wire with the lifting ring 416 on support 412 and support 412 cross bar and occurring stuck phenomenon, thus avoid the generation of construction failure; And the conductive line surfaces of heavy electric power cable is naked state, each lifting wheels 41 adopt two cabling wheels 411 can guarantee that upper and lower surface is rolling friction state with wire, there will not be the situation of sliding friction injured surface; In addition, each lifting wheels 41 adopt two cabling wheels 411, wire clamp are held between two cabling wheels 411, are formed spacing, wire is advanced stably to wire.
During construction, first opposite side electric power tower is delivered to by built on stilts cable laying tractor or line throwing gun or special remote control helicopter in construction one end of light-duty pull rope, draw by the construction of this root with light-duty pull rope and install and carry cable 3; Then on tower, multiple latch 414 walking line mechanism 4 running part is in the air opened by staff successively, and the rotation along with hinge 413 makes latch connection side open formation introducing port, hangs on carrying cable 3, then inserts pin rod, realize the suspension of running part; By pulling the pull rope 6 being connected to running part, make that multiple to walk line mechanism 4 in the air spaced apart, then pull the pull rope 6 of each height below running part respectively, the lifting wheels 41 of each height are staggered mutually, forms mutually non-interfering many air corridors; When line mechanism 4 is walked in suspension in the air, each height lifting wheels 41 below running part are also installed with strop successively, after air corridor is formed, the wire of strop one end with heavy electric power cable is connected, pulls the high-altitude that can realize heavy electric power cable to hand over across unfolding at the other end; The length of aerial lifting rope 42 is according to overhead line conductor spacing choice for use, after circuit installation, removes all set of tools, complete whole construction according to the disposable withdrawal of the step that above installation is contrary.
