Abstract
The utility model relates to a protective steel sleeve for a large-section lead, which is applied to pre-twisted carborundum wire locations and is arranged on the outer side of a lead. The protective steel sleeve is characterized by consisting of two semicircular arc manganese steel components, and connection parts of the two semicircular arc manganese steel components are respectively provided with engraved openings so as to be mutually embedded in use and to form a whole circular arc steel sleeve at the peripheral of the lead. When a pre-twisted carborundum wire is used for tightening the lead, an extrusion force of the pre-twisted carborundum wire on the lead is acted on the lead protective steel sleeve through the protective steel sleeve disclosed by the utility model and is buffered and dispersed by the protective steel sleeve, and thus a problem that the large-section lead is broken by the pre-twisted carborundum wire is solved.
Description
Technical field
The utility model relates to the transmission line field, and particularly, the utility model relates to a kind of large-section lead with the protection steel bushing, and said large-section lead is used for the wire-protecting of transmission line construction with the protection steel bushing.
Background technology
Along with social economy's high speed development, the need for electricity amount also increases greatly, and the conductor cross-section of transmission line is also progressively increasing.Large-section lead because its cross section, weight are bigger, has brought certain inconvenience to operation in maintenance, construction.
Though large-section lead can adopt the diamond dust preformed armor rods to tighten up lead in maintenance, construction, it is better to tighten up effect, when adopting the diamond dust preformed armor rods to tighten up lead, because the contour structures of diamond dust preformed armor rods, and very easily under big stressing conditions, damage wires.
The utility model content
For addressing the above problem; The purpose of the utility model is: provide a kind of simple in structure; Low cost of manufacture, easy to operate large-section lead are with the protection steel bushing, and above-mentioned large-section lead is with protecting steel bushing in transmission line construction; When tightening up lead, can sustain damage under big stressing conditions owing to the contour structures of diamond dust preformed armor rods by guardwire with the diamond dust preformed armor rods.
In addition, adopt the large-section lead of the utility model laborsaving, save time with the work of protection steel bushing.
For achieving the above object, the large-section lead of the utility model is following with the technical scheme of protection steel bushing:
A kind of large-section lead is with the protection steel bushing; Be used for diamond dust preformed armor rods occasion, be installed in the lead outside, it is characterized in that; Said large-section lead is made up of two semicircular arc manganese steel parts with the protection steel bushing; Said two semicircular arc manganese steel parts junctions have the mouth of carving respectively, and are chimeric each other with in use, are combined into as a whole circular arc steel bushing in the lead periphery.
Use the protection steel bushing according to a kind of large-section lead of the utility model; It is characterized in that; The mouth of carving that is formed at said two semicircular arc manganese steel parts junctions forms the groove with gradient respectively, so that fastening after the lead periphery is combined into as a whole circular arc steel bushing.
Use the protection steel bushing according to a kind of large-section lead of the utility model, it is characterized in that, the groove gradient of carving mouth that is formed at said two semicircular arc manganese steel parts junctions is 15-20 °.
According to the utility model, the length of said wire-protecting steel bushing is 180-250mm.
The wire-protecting steel bushing of the utility model is processed by manganese steel, is divided into two semicircular feature, is installed in the lead outside.Wire-protecting steel bushing diameter can be processed according to diameter of wire, two semi-circular features have respectively carve mouthful can be when combination relative fixed, be a cylinder after the combination.
According to the utility model, the length of wire-protecting steel bushing confirms that according to the lead scope of required protection generally getting 180-250mm can meet the demands.
Use the protection steel bushing according to a kind of large-section lead of the utility model; Be prone to by the occasion of diamond dust preformed armor rods damage at large-section lead; When but the diamond dust preformed armor rods tightens up lead; Make the diamond dust preformed armor rods act on the wire-protecting steel bushing, extruding force is cushioned, disperses, thereby solve large-section lead by the problem of diamond dust preformed armor rods damage through the protection steel bushing to the extruding force of lead.
Use the protection steel bushing according to a kind of large-section lead of the utility model, this protection steel bushing structural volume is little, in light weight, easy for installation, uses flexibly, can protect fully when use diamond dust preformed armor rods tightens up large-section lead conscientiously.Overall dimension can customize according to the lead of need protection, and highly versatile is applied widely.
Description of drawings
Fig. 1 is the wire-protecting steel bushing sketch map of the utility model.
Embodiment
Be described further below in conjunction with accompanying drawing and embodiment wire-protecting steel bushing the utility model.
Embodiment
A kind of simple in structure, low cost of manufacture, easy to operate large-section lead is used in the transmission line construction occasion when tightening up lead with the diamond dust preformed armor rods with the protection steel bushing.
A kind of large-section lead is installed in the lead outside with the protection steel bushing; Said large-section lead is made up of two semicircular arc manganese steel parts with the protection steel bushing; Said two semicircular arc manganese steel parts junctions have the mouth of carving respectively; Chimeric each other with in use, be combined into as a whole circular arc steel bushing in the lead periphery.
The mouth of carving of said two semicircular arc manganese steel parts junctions forms the groove with gradient respectively, and the groove gradient of carving mouth that is formed at said two semicircular arc manganese steel parts junctions is 15-20 °.
In addition, in the present embodiment, the length of said wire-protecting steel bushing is 200mm.
Use the protection steel bushing according to a kind of large-section lead of the utility model, this protection steel bushing structural volume is little, in light weight, easy for installation, uses flexibly, can protect fully when use diamond dust preformed armor rods tightens up large-section lead conscientiously.Overall dimension can customize according to the lead of need protection, and highly versatile is applied widely.
