Abstract
The utility model discloses a special setting-out pulley for cluster lead wires. The special setting-out pulley for cluster lead wires comprises a main body and an opening clip arranged at the bottom of the main body. During use, the main body can be fixed on a crossarm by the opening clip, so that the problem that an existing setting-out pulley is clamped by the crossarm or other goods is solved.
Description
Technical field
The utility model relates to the overhead transmission line construction with tension stringing construction equipment field, is specifically related to the special-purpose releasing pulley of Bundling conducting wire.
Background technology
Bundling conducting wire is used by a large amount of in the upgrading of rural power grids.And existing releasing pulley is when carrying out unwrapping wire to parallel Bundling conducting wire, the time regular meeting releasing pulley occurs and blocked by cross-arm or other goods, and then cause the insulating barrier of Bundling conducting wire to be damaged, also can cause the accident of falling the bar when serious.
The utility model content
In view of this, the utility model provides a kind of Bundling conducting wire special-purpose releasing pulley, to solve above-mentioned a series of problem.
The utility model embodiment is achieved in that
The special-purpose releasing pulley of a kind of Bundling conducting wire comprises: main body and the opening clip that is arranged at said bottom part body.
Preferably, the quantity of said opening clip is at least one.
Preferably, said main body comprises: support body; The hook, left side baffle plate, right side baffle plate, the side that are arranged on the support body help wheel and bottom roller.
Can find out from above-mentioned technical scheme; In the utility model embodiment; The opening clip has been installed in the support body bottom of the special-purpose releasing pulley of Bundling conducting wire; Can main body be fixed on the cross-arm through the opening clip during use, thereby when having solved unwrapping wire, the problem that existing releasing pulley is blocked by cross-arm or other goods.
Description of drawings
In order to be illustrated more clearly in and to describe the technical scheme of prior art and the utility model, provided the accompanying drawing of prior art and the utility model specific embodiment below.Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, to those skilled in the art, under the prerequisite of not paying creative work, can also obtain other embodiment according to these accompanying drawings.
The special-purpose releasing pulley structural front view of Bundling conducting wire that Fig. 1 provides for the utility model embodiment;
Special-purpose another structural representation of releasing pulley of Bundling conducting wire that Fig. 2 provides for the utility model embodiment;
The hook structure sketch map that Fig. 3 provides for the utility model embodiment.
Embodiment
The accompanying drawing that will combine the utility model embodiment below carries out clear, intactly description to the technical scheme among the utility model embodiment, and obviously, described embodiment only is the part embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those skilled in the art are not paying the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The full name of Bundling conducting wire is a bunched aerial insulated cable, is with compact the linking together of many (being generally 4) insulated cables during manufacturing with the insulating material dowel.It has parallel (flat row) and side's row by integrated mode, is the compact cable bundle with built on stilts mode work.
The 380/220V network of supplying power with plain conductor in the rural power grids at present is owing to receive effects limit such as investment, circuit corridor and safety; Having formed backbone is three phase supply; Branch line and house lead in are essentially the powering mode of single phase power supply; According to transformed rural power grids statistical analysis, branch line and house lead in account for 70% of total circuit length.
And after adopting the Bundling conducting wire power supply, not only backbone, branch line can be used three phase supply, the also available 4 relatively cheap * 6mm of house lead in
2Or 4 * 10mm
2Lead constitute the three-phase line power supply, make whole network all form three phase supply like this.Can know according to electrotechnics; Under identical load, identical lead physical parameter condition; Adopting the line loss of three phase supply is 1/3 of single phase power supply, and three-phase/two phase networks that the network that therefore adopts the Bundling conducting wire lead to supply power is supplied power than conventional plain conductor reduce the wastage and are 1/3*70%=23%.
Under the pattern of the whole three phase supplies of Bundling conducting wire, load can be accomplished mean allocation basically, and the electric current of the neutral line is zero basically, thereby has eliminated the power loss of the neutral line basically, and load evenly can make the neutral point potential drifting reduce in addition, has improved quality of voltage.
And Bundling conducting wire has that the line is busy corridor, road effectively prevents electric leakage, stealing, and is safe and reliable, handsome in appearance, practices thrift gold utensil, electric pole and backguy, easy construction, advantages such as investment value.
Therefore, Bundling conducting wire is used by a large amount of in the upgrading of rural power grids.And existing releasing pulley is when carrying out unwrapping wire to Bundling conducting wire, the time regular meeting releasing pulley occurs and blocked by cross-arm or other goods, and then cause the insulating barrier of Bundling conducting wire to be damaged, also can cause the accident of falling the bar when serious.
For this reason, the utility model embodiment provides Bundling conducting wire special-purpose releasing pulley, the problem that existing releasing pulley is blocked by cross-arm or other goods when solving unwrapping wire.
Fig. 1 shows a kind of structure of the special-purpose releasing pulley of above-mentioned Bundling conducting wire, and it comprises: main body 101, and the opening clip 1 that is arranged at main body 101 bottoms.The quantity of opening clip 1 can be one or more.
Can main body 101 be fixed on the cross-arm through opening clip 1 in use, when unwrapping wire, be prone to the problem blocked by cross-arm or other goods thereby solved existing releasing pulley.
Concrete, referring to Fig. 2, aforementioned body comprises support body, and is arranged on the support body:
Hook 6 (concrete structure of hook 6 sees also Fig. 3);
Left side baffle plate 2;
Side helps wheel 3;
Right side baffle plate 4;
In use, only need open right side baffle plate 4, parallel Bundling conducting wire is put into support body, utilize hook 6 that main body is hung on the somewhere then, and utilize opening clip 1 that main body is fixed on the cross-arm, just can carry out setting-out work.
Need to prove that each embodiment adopts the mode of going forward one by one to describe in this specification, what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.It will be easy to do concerning those skilled in the art that the non-creativeness of these embodiment is revised, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will protect principle disclosed herein and features of novelty the wideest corresponding to scope.
