Abstract
The utility model discloses a surface contact type wear-resistance ground wire fitting. The fitting comprises a suspension clamp, a connecting rod and a U-shaped screw, wherein the suspension clamp is movably connected with the lower end of the connecting rod through a scroll of the suspension clamp; the upper end of the connecting rod is movably hung at the lower end of the U-shaped screw; and the contact between the U-shaped screw and a U-shaped suspension plate is surface contact. According to the surface contact type wear-resistance ground wire fitting, the contact mode between the U-shaped screw and the rigid buckle is improved into a surface contact mode, so that the contact area of an abrasion part is effectively increased, and the abrasion is effectively reduced. The surface contact type wear-resistance ground wire fitting is suitable for a power transmission circuit.
Description
Technical field
The utility model relates to the gold utensil for transmission line, particularly relates to a kind of face contact type wear-resistant ground wire hardware tool.
Background technology
At present, China's mountain area 500kV transmission line is in running, find that in succession the wearing and tearing of overhead ground wire XGU type suspension clamp hull hanging scroll and U-shaped link are up to the critical defective of sectional area 50%-70%, the only 4-5 and the newly-built circuit of part puts into operation, the safe operation of 500kV extra high voltage network constituted a serious threat, and in a single day ground wire hardware tool wear and rupture fault appears in the 500kV circuit, will bring huge economic loss, its reason mainly contain following some:
The one, the U-shaped screw of former gold utensil is that point contacts with the way of contact of U-shaped link, is subjected to like this force intensity high, easily wearing and tearing;
The 2nd, easily wear and tear in suspension clamp hanging scroll place.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of wear-resisting face contact type wear-resistant ground wire hardware tool to be provided.
In order to realize above purpose, a kind of face contact type wear-resistant ground wire hardware tool that the utility model provides, comprise: suspension clamp, connecting rod and U-shaped screw, described suspension clamp is flexibly connected by the lower end of suspension clamp hanging scroll and described connecting rod, the upper end of described connecting rod is articulated in the lower end of described U-shaped screw by U-shaped link plate activity, the way of contact of described U-shaped screw and U-shaped link plate is that face contacts.Be improved to face by the way of contact with described U-shaped screw and U-shaped link plate and contact, effectively increased the contact area of abrading section, effectively reduce wearing and tearing.
In such scheme, the cross section that interconnects end of described U-shaped screw and U-shaped link plate is rectangle, and four jiaos of described rectangle are rounded down respectively, are convenient to like this swing between described U-shaped screw and the U-shaped link plate.
In such scheme, described suspension clamp hanging scroll is set with anti-wear sleeve outward, has improved the wearing and tearing at suspension clamp hanging scroll place.
In such scheme, described suspension clamp is the handbag type wire clamp, lags behind the deflection of wire because of the rotation of handbag type wire clamp, so the relative center steering formula of rate of depreciation wire clamp has reduced much.
The utility model is improved to face by the way of contact with described U-shaped screw and U-shaped link plate and contacts on the one hand, has effectively increased the contact area of abrading section, effectively reduces wearing and tearing; On the other hand, the cross section that interconnects end of described U-shaped screw and U-shaped link plate all is designed to rectangle, and at four jiaos of described rectangle roundings respectively, is convenient to the swing between described U-shaped screw and the U-shaped link plate; On the one hand, outside described suspension clamp hanging scroll, add anti-wear sleeve again, improved the wearing and tearing at suspension clamp hanging scroll place; At last, by selecting the handbag type wire clamp to reduce rate of depreciation.
The utility model is compared with the prior art, and shows that fully its superiority is: wear-resisting and simple in structure etc.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1.
Among the figure: suspension clamp 1, connecting rod 2, U-shaped screw 3, suspension clamp hanging scroll 4, U-shaped link plate 5, anti-wear sleeve 6.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
The present embodiment provides a kind of face contact type wear-resistant ground wire hardware tool, comprise: suspension clamp 1, connecting rod 2 and U-shaped screw 3, described suspension clamp 1 is flexibly connected by the lower end of suspension clamp hanging scroll 4 with described connecting rod 2, the upper end of described connecting rod 2 is articulated in the lower end of described U-shaped screw 3 by U-shaped link plate 5 activities, the way of contact of described U-shaped screw 3 and U-shaped link plate 5 is that face contacts.Be improved to face by the way of contact with described U-shaped screw 3 and U-shaped link plate 5 and contact, effectively increased the contact area of abrading section, effectively reduce wearing and tearing.
The cross section that interconnects end of above-mentioned U-shaped screw 3 and U-shaped link plate 5 is rectangle, and four jiaos of described rectangle are rounded down respectively, are convenient to like this swing between described U-shaped screw 3 and the U-shaped link plate 5.Be set with anti-wear sleeve 6 outside the described suspension clamp hanging scroll 4, improved the wearing and tearing at suspension clamp hanging scroll 4 places, and suspension clamp hanging scroll 4 is carried out the carbo-nitriding low-temperature tempering heat treatment, improve its hardness and anti-wear performance.Described suspension clamp 1 is the handbag type wire clamp, lags behind the deflection of wire because of the rotation of handbag type wire clamp, so the relative center steering formula of rate of depreciation wire clamp has reduced much.
The utility model is improved to face by the way of contact with described U-shaped screw 3 and U-shaped link plate 5 and contacts, and has effectively increased the contact area of abrading section, effectively reduces wearing and tearing; The cross section that interconnects end of described U-shaped screw 3 and U-shaped link plate 5 all is designed to rectangle, and at four jiaos of described rectangle roundings respectively, is convenient to the swing between described U-shaped screw 3 and the U-shaped link plate 5; Outside described suspension clamp hanging scroll 4, add anti-wear sleeve 6, improved the wearing and tearing at suspension clamp hanging scroll 4 places; At last, by selecting the handbag type wire clamp to reduce rate of depreciation.
