Description
Technical field
The utility model relates to the power line construction utensil, protects and does not cause by the construction keeping device of construction lead wire and earth wire friction damage striding 10KV and above power circuit down during especially for power line construction.
Background technology
In power transmission lines overhauling work, usually run into the work of changing lead wire and earth wire and removing lead wire and earth wire; how to handle at work and protect down and stride 10kV and above power circuit key problem often; in construction in the past, usually adopt following several processing methods:
1, loose ends method: will descend cross-line road pine to ground before the main body construction, and treat that main body construction finish cross-line road under recovery, back.The method is safe and reliable, but construction is complicated, construct consuming time, expend many.
2, crossing frame method: under stride a place and set up crossing frame, crossing frame is divided into unilateral crossing frame and closed crossing frame (closed crossing frame is used for the live across construction more).The method fail safe is higher, but is subjected to landform, and following cross-line road is to influences such as ground levels, and limitation is big, and construction is complicated, construct consuming time, expend many.
3, suspension ring method: adopt method at the crossover point place with suspension ring, rope, make lead wire and earth wire away from the circuit of striding down, thereby play a protective role with line messenger wire (lead hang ground wire, ground wire hang lead, lead hangs lead).The method is simple, and the feasibility height is consuming time few.
As fully visible, the suspension ring method is simple, extensively adopts in construction.If but run into crossover point at the water surface, and those suspension ring just are difficult to forget about it crossover point, and the below also is difficult for looking for fixing point, and crossover point building, power line are comparatively concentrated or in the woods time, the suspension ring construction is also extremely difficult; In dismounting work, last single line does not have line extension suspension ring to protect.How these three kinds of situations this solve, and construction is just simple and reliable, becomes technological difficulties.
The utility model content
The purpose of this utility model provides a kind of simple in structure, installation, convenient disassembly, effective protection cross-line road protector under the power line construction of mutual conductance ground wire down.
This novel purpose is achieved in that cross-line road protector under a kind of power line construction, comprises outer cover: be shaped as cylindrical shell, the axially open of packing into for protected lead wire and earth wire is arranged at the bottom; Be used for fixing drag rope, make the outer two pairs of links that move on the protected lead wire and earth wire that cover on: a pair of link be separately fixed at outer cover axis opening left end two along along last, the two shifts to install, the spacing that staggers is not less than protected lead wire and earth wire diameter, and the two overlaps on the outer cover axis, and another is arranged on two beads of outer cover axially open right-hand member symmetrically to link; Construction lead wire and earth wire barrier structure: be separately positioned on two ends, outer cover top.
The concrete using method of the utility model:
The workmen climbs up by the other electric pole (iron tower) of crossover point; the wire-protecting device is installed on the lead that might be damaged in the work progress (for the circuit that adopts porcelain pole arm or pin type porcelain vase; lead should be turned at iron cross arm; and pull rope is tied up on the link of wire-protecting device in case excessive the causing the accident of when construction lead pressure).Below workmen's dragline messenger is pulled to the crossover point below with protector, and as required, the passable position of protector can be adjusted according to actual needs in the work progress.After construction finished, the pull rope of pulling back was again removed protector.
At the water surface, the workmen can spur protector by ship as crossover point, and the stationary rope of protector can bolt on the coast or on the ship; In the woods, protector can be pulled to crossover point along following cross-line road as crossover point; Solved in the dismounting work, last single line does not have line to hang the problem that suspension ring are protected yet.
The beneficial effects of the utility model are:
1, mainly form by an outer cover cylindrical shell, simple in structure, low cost of manufacture.
2, easy to use
During installation, the outer cover cylindrical shell is enclosed within on the protected lead wire and earth wire from axially open, can uses drag rope easily; it is slided on lead wire and earth wire; to descending the mutual conductance ground wire to play the insulation blocking effect, during dismounting, only need unload the outer cover cylindrical shell and get final product from lead wire and earth wire.Have characteristics easy to use.
3, protect time mutual conductance ground wire effectively, helped the carrying out of stringing construction.
The wire-protecting device directly is installed on the circuit of striding down, and the wire-protecting device is installed in the crossover point below, and lead wire and earth wire is moved on the wire-protecting device during construction, thereby has protected time cross-line road.
