Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is connected with external yoke plate and load instrument.
Embodiment
As depicted in figs. 1 and 2, of the present utility model pair of insulator string balance hanging point fastening means comprises two high density aluminium alloy plates 1 that up and down parallel stack is provided with, two high density aluminium alloy plate 1 one end openings and the corresponding fixed bolt hole 2 that is provided with, fixed bolt hole 2 is used for being connected with external yoke plate (comprising three yoke plates 8 and tetrad plate 9 as shown in Figure 2), two high density aluminium alloy plate 1 other ends link together and are fixed with the high strength shackle, this high strength shackle comprises U-shaped bar 5 and shackle bolt 6, nut 4, and the body of rod of U-shaped bar 5 openend both sides is provided with through hole 5A.Shackle bolt 6 is located in the through hole 5A during use, and its right part is passed the through hole 5A on right side and by nut 4 it is locked in the through hole 5A, and fastening nut 4 will make nut 4 compress the body of rod 5 of U-shaped bar.Shackle bolt 6 is used for and external load instrument 7 clasp joint mutually, and the closing end of U-shaped bar 5 is connected on the high density aluminium alloy plate 1.Wherein, the gap between all thick 10 millimeters of two the high density aluminium alloy plates 1, two high density aluminium alloy plates 1 is 15 millimeters; The maximal destruction power of high strength shackle is 50KN, and the diameter of U-shaped bar 5 is 18 millimeters.
As shown in Figure 2, external yoke plate comprises three yoke plates 8 on top and the tetrad plate 9 of bottom.The utility model needs to use in pairs when changing insulator string, one of them is fixedlyed connected with three yoke plates 8 that are plugged between two high density aluminium alloy plate 1 by the nut bolt pin 11 that is located in its fixed bolt hole 2, another is fixedlyed connected with the tetrad plate 9 that is plugged between two high density aluminium alloy plate 1 by the nut bolt pin 11 that is located in its fixed bolt hole 2, with load instrument 7 two link up with 12 difference clasp joints on the shackle bolt 6 of two two insulator string balance hanging point fastening meanss then, make this pair insulator string balance hanging point instrument in two bunch of insulator centers like this, exist together on the straight line with wire tension, play the stressed balanced action of strain insulator shaft tower cross-arm during traction.Insulator string is lax when tightening up load instrument 7, just can take off and change insulator, need not use too much utensil, and efficiency of construction is higher, can promote the operation utilance of transmission line.
Certainly, the utility model includes but not limited to present embodiment, not necessarily will be 15 millimeters as the gap between two high density aluminium alloy plates 1, needs only the plate body thickness greater than external yoke plate; Concrete numerical value such as the diameter of other U-shaped bars 5 also can be set to other concrete numerical value under the condition of satisfying the demand, this type of conversion all drops within the protection range of the present utility model.
