Embodiment
For ease of understanding, below in conjunction with accompanying drawing, concrete structure of the present utility model is elaborated.
The utility model is made up of parts such as bearing rope 20, hanging tackle pulley 30, coaster tricing line 33, wires-erecting pulley 40, suspension bracket 60 and suspension bracket tricing lines 31, is described below:
1. bearing rope 20
As shown in Figure 1, 2, the bearing rope 20 in the utility model is be erected at original place line GJ-50/GJ-80 on crossover tower 10 or wire.
2. hang tackle pulley 30 and coaster tricing line 33
As shown in Figure 1, 2, 3, the hanging tackle pulley 30 in the utility model comprises the first coaster 31 and the second coaster 32, and described first coaster 31 is arranged on upside, and the second coaster 32 is arranged on downside, and described first coaster 31 and the second coaster 32 are and unload button-type coaster; Described first coaster 31 hangs upside down on bearing rope 20, and the shackle of the first coaster 31 overhangs downwards and is fixedly connected by being with φ 15.5 × 1.5m steel wire rope of wire clips with the shackle of the second coaster 32.
As shown in accompanying drawing 1 ~ 3, one end of described coaster tricing line 33 is fixedly connected with wires-erecting pulley 50 through after the race of the second coaster 32 middle pulley, and the other end of coaster tricing line 33 fixes on the ground by boring stake 35.Described coaster tricing line 33 is the insulation Du Pont rope of φ 13 × 100m, thus just can the height of regulable control wires-erecting pulley 40 and position when regulating the length of coaster tricing line 33, with meet span line to by the safe distance of leap thing requirement.
3. wires-erecting pulley 40
Wires-erecting pulley 40 is nylon coaster, is worn when constructing to prevent wire or optical cable 50.
4. suspension bracket 60 and suspension bracket tricing line 31
It is pointed out that suspension bracket 60 is not required in this device, when being alive circuit by leap thing, suspension bracket 60 is comparatively suitable for.Suspension bracket 60 can be suspension bracket set square, and during construction, suspension bracket 60 is hung on the nearer ground wire of distance span line or wire; Same, suspension bracket tricing line 31, for the height of regulable control suspension bracket 60 and position, is beneficial to construction.
Below in conjunction with accompanying drawing 1,2,3, the course of work of the present utility model is described further.
As shown in Figure 1,3, for spanning overhead line, first crossed by impelling rifle in crossed line side and discharge an optical cable, ground wire is connected as bearing rope 20 in optical cable one end, by tower bar traction optical cable simultaneously over the ground drum slightly brake, make ground wire stressed unsettled by crossed line, until ground wire arrives tower bar, stop traction.Unclasp ground wire to ground, ground wire hangs upside down the first coaster 31, the first coaster 31 mounts the second coaster 32, penetrate coaster tricing line 33, tighten up ground wire in the race of the second coaster 32, now the first coaster 31 and the second coaster 32 are all raised in the air.Coaster tricing line 33 one end is connected with wires-erecting pulley 40, and the other end of coaster tricing line 33 is connected with brill stake 35.The pulley of simultaneously wires-erecting pulley 40 is placed with guide rope, pulls coaster tricing line 33 until wires-erecting pulley 40 is higher than crossed line, and keep enough safe distances, fixed block tricing line 33, keep wires-erecting pulley 40 suspention to be positioned above crossed line.Pull guide rope to be replaced with pull rope, pull rope makes optical cable 50 across crossed line, until the leap completing optical cable 50 is discharged.
Repeat to pull coaster tricing line 33, put down wires-erecting pulley 40, the pulley of wires-erecting pulley 40 discharges guide rope, discharge another root wire, until all leads span stringings all terminate.
As shown in Figure 2,3, when crossed line is alive circuit, guide rope is not placed with when wires-erecting pulley 40 is raised to aerial under the effect of hanging tackle pulley 30, but by the workmen on suspension bracket 60, guide rope is passed each wires-erecting pulley 40 successively, thus complete discharging of guide rope, then pull guide rope to be replaced with pull rope, pull rope makes optical cable 50 across crossed line, until the leap completing optical cable 50 is discharged.
