Following with reference to description of drawings one embodiment of the present of invention, Fig. 1 is the end view of wedge shape anchor clamp of the present invention, and Fig. 2 is its cross-sectional side elevational view, and Fig. 3 is the cutaway view along the III-III line of Fig. 1.
Wedge shape anchor clamp 1 is provided with the connecting plate 2 that the insulator frame accessory G that is connected in iron tower uses, with the chimeric rotationally body 4 of bolt 3 that is fixed on this connecting plate 2, inboard and the chimeric rotationally wedge support piece 5 of bolt 3 at this body 4, at the chimeric reinforcement plate 6 of the outside of body 4 and bolt 3, voussoir 7, and cross-over connection accessory 8.
Connecting plate 2 is made of two steel plates, clips stringing in substantial middle and fixes with drag hook 10 usefulness bolts 9, is formed with in its end and installs with bolt hole 11.One end of bolt 3 has hemispherical nose, twists intrinsic nut on the other end.Body 4 is formed by aluminium alloy, and section is the U font, and the side is roughly triangular in shape, is formed with the groove 12 that electric wire W inserts usefulness in its bottom.Reinforcement plate 6 is made for light-alloy, and section forms the U font, so that contact with the lateral wall of body 4, and is fixed on the outside of body 4 by screw 6a.Wedge support piece 5 is leg-of-mutton flat aluminium alloy plates, is formed with the interval of regulation between the bottom side 12a of the slot part 12 of its bottom side 5a and body 4.
To shown in Figure 6, voussoir 7 is made up of top thin 7a of wedge portion and clamping part 7b, runs through 7a of wedge portion and clamping part 7b at downside, is formed with the groove 13 of circular arc as Fig. 4.The radius of this groove 13 roughly equates with the radius of the electric wire W that is fixed.This groove 13 has slightly the lug boss 13a to lower convexity at the clamping part 7b place of voussoir 7.In addition, the clamping part 7b of voussoir is shown in Fig. 5,6, and upper width narrows down, and the both sides, bottom are formed with a pair of extension 15a, 15b and 16a, 16b respectively, and the centre is provided with breach 14a, 14b.
To shown in Figure 9, cross-over connection accessory 8 is crooked downwards as Fig. 7, and the surface is formed with the same groove 17 relative with the groove 13 of voussoir 7 along curved surface thereon.Be formed with the relative recess 17a of lug boss 13a with the groove 13 of voussoir 7 with the groove 17 of the cross-over connection accessory 8 of the clamping part 7b corresponding position of voussoir 7, so that clamping electric wire W reliably.At the sidepiece of cross-over connection accessory 8, corresponding with the clamping part 7b of voussoir 7, be formed with a pair of extension 19a, 19b and 20a, 20b respectively, be provided with breach 18a, 18b in the centre.On each extension 19a, 19b and 20a, 20b, be respectively equipped with hole 22a, 22b and 23a, the 23b of the pin 21 that is fixed with as shown in figure 10.
Make the 24a of annulus portion of band eyelet I type bolt 24 1 ends of being located at shown in Figure 10 and 11 embed breach 18a, 18b respectively, and eyelet 25 is alignd respectively with hole 22a, 22b, 23a, 23b, pin 21 insertions are fixed in these holes 22a, 22b, 23a, the 23b.Because the internal diameter of the eyelet 25 of I type bolt 24 is bigger than the diameter of pin 21, thus I type bolt 24 be connected on the cross-over connection accessory 8 by pin 21, and can be to lateral rotation shown in the arrow of Figure 10.Packing ring 27 and nut 26 are installed on the I type bolt 24.In addition, also can be arranged on hole 22a, 22b, 23a, the 23b of steady pin 21 usefulness on the extension 15a, the 15b that are located at voussoir clamping part 7b both sides, 16a, the 16b, the pin 21 of the eyelet 25 that passes I type bolt 24 is fixed on the hole of voussoir 7, and breach 18a and 18b only are set on cross-over connection accessory 8.
Figure 13 shows the variation of clamping part.Both sides at the clamping part 7b of voussoir 7 are formed with extension 15a, 15b and 16a, 16b, this extension is formed with breach 14a, the 14b to both-side opening, on extension 16a, the 16b, be provided with hole 30a, the 30b of pin 21 usefulness that fixedly pass across breach 14b therein.
As shown in figure 14,, be provided with the extension 28 of L font as illustrated in fig. 15, form porose 29 at this in the position suitable of cross-over connection accessory 8 with the clamping part 7b of voussoir 7.The extension of other sides is identical with last example.
Like this, voussoir 7 all is connected with I type bolt with fastening with cross-over connection accessory 8, can prevent that each part scatters and disappears.In addition, on voussoir clamping part 7b, L font extension as shown in figure 15 is set, this extension is articulated on the pin that is fixed on the extension of being located in cross-over connection accessory 8 both sides, formation extension jaggy and steady pin are set in the other side, be articulated in I type bolt on this pin by an end,, also can receive same action effect at cross-over connection accessory side configuration nut and fastening.
As shown in Figure 1, be provided with the clamping device 41 of jumper in the top ends of cross-over connection accessory 8.Promptly shown in Figure 16,17, be provided with extension 32a, the 32b that is formed with breach 31 at a sidepiece in the top ends of cross-over connection accessory 8, be formed with the extension 34 of the L font the same with Figure 15 in the other side, form porose 35 on it.
Clamping device 41 places of cross-over connection accessory 8 use relative supporting member 42.This supporting member is not made concrete diagram, but has the shape roughly the same with the clamping part 7b of voussoir shown in Figure 13 7.Therefore, identical with the relation of cross-over connection accessory 8 and I type bolt with voussoir shown in Figure 15 7, the extension of supporting member 42 and cross-over connection accessory 8 34 is connected by pin free to rotately, in the other side, by inserting, being fixed on the pin in hole 33a, the 33b, connecting I type bolt free to rotately.
The fixing means of electric wire W to anchor clamp then is described.At first voussoir 7 is fixed in electric wire W, meanwhile, also carries out the fixing of cross-over connection accessory 8.
Electric wire W is inserted in the body 4 in advance.Than position slightly left, position shown in Figure 1, voussoir 7 is placed on the electric wire, and cross-over connection accessory 8 is resisted against under the electric wire.Hold up a pair of I type bolt 24 of cross-over connection accessory 8 then as shown in figure 10, in breach 14a, the 14b of the clamping part 7b of the part of packing ring 27 downsides insertion voussoir 7.Then by screwing nut 26, packing ring 27 is crimped on extension 15a, 15b, 16a, the 16b, and voussoir 7 and cross-over connection accessory 8 are securely fixed on the electric wire W.Similarly, the clamping device 41 on cross-over connection accessory 8 tops also is bolted on the electric wire by supporting member 42 and I type.By electric wire W is drawn to right-hand, voussoir 7 is pushed into the downside of wedge support piece 5 then, and electric wire is fixed on the anchor clamp.
Figure 18 is the front view that anchor clamp second embodiment of the present invention is shown.In the part identical, put on the symbol identical, and omit explanation with this figure with first embodiment.In first embodiment, I type bolt 24 is set at a place, but in a second embodiment, is provided with two U-bolts 43,44 at Liang Chu.The downside of the inner bottom part of each U-bolt and cross-over connection accessory 8 projects upwards run through the hole of extension 46 of voussoir 45 against, the top of bolt after, loads onto double nut 47 and tightens at this, and cross-over connection accessory 8 promptly is fixed on the voussoir 45.Other structure is identical with first embodiment.If adopt present embodiment, because with U-bolt fixedly cross-over connection accessory and voussoir, so simple in structure, the connection operation is also easy.
As seen from the above description, if adopt the present invention, can utilize anchor clamp simple in structure to hold electric wire reliably.Have again, can prevent to cause the distortion and the transverse runout of jumper because of the cross-over connection accessory.
