Abstract
The utility model relates to a U-shaped hanging ring for a transmission line, belonging to the metal wares of the transmission line. A coupling segment (4) of the U-shaped hanging ring is formed by an elliptical cylinder with an inner hole (7), and the axial lead of the elliptical cylinder is identical with a coupling bolt (5). A long axis of which the surface forms an elliptical shape is arranged along a long direction of the U-shaped hanging ring so as to increase the longitudinal edge thickness of the coupling segment (4), and thus, the utility model has the advantages of high longitudinal tensile strength, and long service life. The utility model is suitable for using when a high-voltage transmission line is erected in districts of bad weather condition and bad natural environment.
Description
The utility model relates to transmission line hardware, particularly is connected in the U type link between hanging point gold utensil and the link plate.
At present the U type link that uses in China's ultra-high-tension power transmission line all as shown in Figure 4, it connects the Cylinder that section is the band endoporus, connecting section, to go up endoporus vertically the same with horizontal edge thickness along U type link.Because U type link in use, coupling bolt (5) is subjected to respectively from the opposite pulling force of the direction of hanging point gold utensil and link plate, thereby the connection section also mainly is subjected to the opposite longitudinal pulling force effect of a pair of direction, usually be that tensile strength is limited is longitudinally broken because of connecting section in the use, shortened the useful life of U type link.
Thereby the purpose of this utility model provides a kind of link connecting section tensile strength and make it be difficult for being broken the U type link that prolongs its useful life longitudinally that strengthens just in order to overcome above-mentioned weak point of the prior art.
The purpose of this utility model is achieved by the following technical solution.
The connecting section of this transmission line U type link is the ellipse Cylinder of the axial line band endoporus identical with attachment bolt, and the major axis of ellipse garden face is along vertical setting of U type link.
Because the link connecting section makes ellipse garden shape, its longitudinal edge thickness increases, and can strengthen its tensile strength longitudinally greatly, thereby makes it be difficult for being broken and prolonged useful life.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a front view of the present utility model,
Fig. 2 is a left view of the present utility model,
Fig. 3 is the front view of prior art,
Fig. 4 is the left view of prior art.
U type link main body 1 and connecting section 4 usefulness carbon constructional quality steel solid forgings form, key is connecting section 4 to be forged the ellipse Cylinder of band endoporus as shown in Figure 2, link main body 1 is swaged into arc transition with the place of connecing, street of connecting section 4 and is connected, damage in order to avoid cause stress to concentrate herein, main board with the hanging point gold utensil inserts in the opening at U type link connecting section place then, coupling bolt 5 is passed the endoporus 7 of U type link connecting section and the bunch-hanged hole of hanging point gold utensil main board successively, the other end at coupling bolt 5 is equipped with nut 6 again, and closed pin 8 gets final product.
Through verification experimental verification, the utility model along U type link longitudinally tensile strength substantially exceed prior art, prolong useful life greatly.Be particularly suitable for setting up in the ultra-high-tension power transmission line and use in weather conditions and the abominable area of natural environment.
Claims (1)
1, transmission line U type link, comprise U type ring main body (1), with main body (1) monobloc forging be that its lateral surface (2), (3) of one are the connecting section on plane (4), attachment bolt (5) and nut (6), it is characterized in that, connecting section (4) is the oval cylinder of the axial line band endoporus (7) identical with attachment bolt, and the major axis of ellipsoid is along vertical setting of U type link.
