Description
Technical field
The utility model relates to a kind of bolts of overhead transmission line road to replace tool, and in particular to a kind of aerial earth wire extension
Point bolt replaces tool.
Background technique
Overhead transmission line due to running outdoors for a long time, inclement condition.Overhead ground wire is protection overhead transmission line
From the device of lightening strikes, usually steel strand wires is mostly used to form, overhead ground wire improves line it is possible to prevente effectively from lightning stroke trip
The safety of road transport row is the important component part of transmission line of electricity.The gravity of overhead ground wire is all born by hanging point bolt,
Under wind-force effect, phenomena such as aerial earth wire is often waved, vibrated, the abrasion of hanging point bolt is exacerbated, therefore, the extension of aerial earth wire
Point bolt usually needs replacing.
During actual job, since hanging point bolt carries whole gravity of aerial earth wire, when replacing fitting, need
Lift aerial earth wire using tool, offsets the aerial earth wire gravity that fitting is subject to, just can be carried out replacement fitting.500kV line at present
Road replacement aerial earth wire hanging point bolt generally uses the Lever Blocks of 1.5T for lifting device, using U-shaped ring as on Lever Blocks
Then suspension hook hitch point catches on aerial earth wire with lower suspension hook, after aerial earth wire promotes certain altitude, the lifting force of Lever Blocks
The gravity of aerial earth wire is offset, operating personnel can replace at this time.Due to the total length of aerial earth wire connection gold utensil
Usually in 400mm or so, Lever Blocks transmission device is larger, leads to ground wire installation site operation faciostenosis, and worker is inconvenient to grasp
Make, average time activity duration is 64 minutes, and in livewire work, since Lever Blocks tail portion iron chains is longer, tail chain is sagging to be made
The safe distance for obtaining conducting wire and iron chains is inadequate, easily causes single-line to ground fault.
In addition, 1.5T Lever Blocks own wt is larger, the artificial upper tower of carrying is larger to the physical demands of worker；Hand pulls calabash
Reed does not have dedicated steel tower fixing end, is fixed by rope sling and U-shaped ring, mounts and dismounts cumbersome, promoted in rotating spanner aerial
During ground wire, lever hoist operation planar is parallel with aerial earth wire in vertical direction, and worker is in the inconvenience of ground wire cross-arm top
Operation.
Domestic invention has the tool for promoting ground wire at present, but the new tool invented at present is only for certain particular columns
Type is effective, is not suitable with a variety of towers, is not able to satisfy the actual needs of existing 500kV route.500kV route mostly uses greatly JLB4-
150 type ground wires, JLB4-150 ground wire maximum working tension 31598N, average running tension 12346N-13514N table look-up and know
Wire quality M=696.7kg/km of JLB4-150 type ground wire unit length, the ground mm of cross-sectional area S=148.072, administrative route
Maximum away from being 524 meters, then on steel tower hanging point bolt bear aerial earth wire gravity F are as follows: the N of F=11574.It is provided by consulting
Expect, generally to retain the safety factor of 20%-30% in engineering science for specified amount of support, choosing safety factor is 25%, i.e. 11574N
× 1.25=14467.8N, therefore, if need to lift aerial earth wire, the lifting force of tool is at least 15000N, it can uses the work
Tool carries out replacement aerial earth wire fitting.
