Described insulating bar has three, along on the outer peripheral face that radially is fixedly mounted on steel ring of steel ring.
Further: described steel ring is by three sections arc steel plates successively hinged the forming of head and the tail, and described three insulating bars are separately fixed on three sections arc steel plates.
Further: the bottom of described three sections arc steel plates is equipped with the reinforced region of widening that extends to form downwards, described widen reinforced region respectively corresponding be positioned at every insulating bar under.
Further: described locking device comprises button, lock body, level is provided with and can passes the second with holes of locking strip on the lock body, be provided with a longitudinal hole second above with holes on the lock body, described button can slide up and down and is installed in this longitudinal hole, spring by vertical setting between button bottom and the lock body is connected, level is provided with and can passes the first with holes of locking strip on the button, on the described button when being subjected to compressive load the described first second top with holes that is positioned at holes.
Further: also comprise a ratchet-type tightener, described ratchet-type tightener and described locking device are fixed on the same end of steel ring opening part.
The beneficial effects of the utility model are: this apparatus structure is simple, and fitting operation is convenient, has saved the set-up time, is conducive to rapid rush-repair.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of locking device in the utility model;
Fig. 3 is another view of locking device in the utility model;
Among the figure: 1 ratchet-type tightener, 2 locking devices, 21 buttons, 22 lock bodies, 23 springs, 24 first is with holes, and 25 second is with holes, 3 restraint zones, 4 insulating bars, 5 steel rings, 51 arc steel plates, 52 widen reinforced region.
Embodiment
As shown in Figure 1, fix on this bypass flexible cable bar and use insulator crossarm, mainly comprise steel ring 5, insulating bar 4, restraint zone 3 and locking device 2, ratchet-type tightener 1.
Described steel ring 5 is for being provided with the annular of opening; This steel ring 5 is by three sections arc steel plates 51 successively hinged the forming of head and the tail.Three insulating bars 4 are separately fixed on three sections arc steel plates 51.Insulating bar 4 is provided with three, along on the outer peripheral face that radially is fixedly mounted on steel ring 5 of steel ring 5.The bottom of three sections arc steel plates 51 be equipped with extend to form downwards widen reinforced region 52, described widen reinforced region 52 respectively corresponding be positioned at every insulating bar 4 under.
One end of described restraint zone 3 is stiff end, and this stiff end is fixed on the end of steel ring 5 opening parts; The other end of restraint zone 3 is free end.
Described locking device 2 is installed on the other end of steel ring 5 opening parts, is used for cooperating with the free end of restraint zone 3 and locking restraint zone 3, ties tight on bar to realize restraint zone 3.
As shown in Figure 2, described locking device 2 comprises button 21, lock body 22, level is provided with and can passes second with holes 25 of restraint zone 3 on the lock body 22, above second with holes 25, be provided with a longitudinal hole on the lock body 22, described button 21 can slide up and down and is installed in this longitudinal hole, spring 12 by vertical setting between button 21 bottoms and the lock body 22 is connected, level is provided with and can passes the first with holes 24 of restraint zone 3 on the button 21, described first with holes 24 is positioned at second with holes 25 top when being subjected to compressive load on the described button 21.
This insulator crossarm also comprises a ratchet-type tightener 1, and described ratchet-type tightener 1 is fixed on the same end of steel ring 5 opening parts with described locking device 2.The structure of this ratchet-type tightener 1 is prior art, repeats no more.
During use, at first steel ring 5 is wrapped on the shaft tower, press the button 21, the free end of restraint zone passes first with holes 24, second with holes 25 of locking device, and the free end of restraint zone continues across ratchet-type tightener 1, the depressed state of hold button 21 (as shown in Figure 3), utilize ratchet-type tightener tension restraint zone 3, then release button 21, the first with holes 24, second 25 dislocation with holes, thereby to the locking of the free end of restraint zone 3, and ratchet-type tightener 1 also plays the locking effect to restraint zone 3, and double locking is so that locking effect is more reliable like this.After restraint zone 3 lockings, this insulator crossarm namely is packed on the shaft tower.
Because steel ring 5 adopts three sections arc steel plate 51 hinged forming, again in conjunction with soft restraint zone 3, so this insulator crossarm can be fixed in any position of shaft tower, and is not limited to a place of shaft tower, is not subjected to the restriction of shaft tower diameter.
After the installation, again the bypass flexible cable is utilized respectively the cable static line to be fixed on the corresponding insulator crossarm 4 and get final product.Because the bypass flexible cable is heavier, be provided with and widen reinforced region 52, can increase the support performance of steel ring 5.
