Due to the adoption of the method, the operating safety can be enhanced, the working efficiency is increased, and the operating personnel can fasten a damper fixing bolt by using an insulated operating rod type fastener on a tower with an indirect live working method (ground potential working).
Description
Technical field:
The present invention relates to a kind of method of charged secure wires stockbridge damper bolt.
Background technology:
The lead stockbridge damper is one of important protection gold utensil of transmission line, and significant feature is to avoid lead in running, not receive the damage that is caused by the wind vibration.The installation of lead stockbridge damper all requires to install according to defined through calculating the back; In case stockbridge damper generation slip positioning does not just have its antihunt action; Make hitch point that the vibration of lead constantly has been sent to lead suspension clamp place just; Finally cause lead to produce metal fatigue, and disconnected burst of broken string accident of lead takes place.
In order to prevent that the lead stockbridge damper from continuing to take place the slip positioning; In maintenance process, at first to the stockbridge damper of positioning be resetted; Will the stockbridge damper of not positioning being tightened up then, all is that combined circuit power failure chance establishment officer carries out surprise and tightens up generally speaking.It is the low-down work of a big operating efficiency of labour intensity that but stockbridge damper tightens up in the circuit service work; To hang on and hang up properly rope ladder or vertical ladder behind operating personnel's rod-rising tower; Then down to lead; On lead, hang up properly coaster again, slide into a side stockbridge damper place under the personnel to the coaster and carry out fasteningly, return then under the upper conductor and carry out fastening to opposite side.Four-player group of the many inefficiencys of the Work tool of being with a day accomplish the fastening work of 3-4 base at most.
Summary of the invention:
For overcoming the defective of prior art; The object of the present invention is to provide a kind of method of charged secure wires stockbridge damper bolt; With improve processing safety, increase work efficiency, through indirect live line working method (earth potential working), on shaft tower, carry out fastening to the stockbridge damper set bolt by the operating personnel with insulating bar, fastener.
Technical solution problem of the present invention adopts following technical scheme:
The method of charged secure wires stockbridge damper bolt, it is fastening to adopt bolt tightener that said lead stockbridge damper bolt is carried out, and said fastener comprises:
Front end is provided with the ratchet spanner of ratchet carriage, is provided with the strip groove on the handle of said ratchet spanner along its length;
Can be along the slide block of the slip of the groove on the said handle, said slide block is provided with locking member and can said slide block be lock onto on the handle, and the end of said locking member connects with action bars; Said locking member comprises: the boring nut that is fixed on said slide block lower end; The fastening bolt that cooperates with said snail box thread; The inner chamber that the upper end of said fastening bolt extends into said slide block can contact with the outer wall of said handle, and the lower end of fastening bolt is provided with the cross draw-in groove and connects with action bars;
Said slide block is socketed on the handle of said ratchet spanner with the inner chamber of its hollow, and slide block is provided with the caging bolt that in said groove, passes;
The fastening of lead stockbridge damper bolt carried out according to the following steps:
1) operating personnel carries bolt tightener and gets into the cross-arm position on the bar; Transmit rope by the Ground Operation personnel with insulation action bars is passed to operating personnel on the bar that is in the cross-arm position; The operating personnel carries out positive connection with fastener and action bars on the bar, confirms that the direction adjusting knob on the ratchet carriage is in the tram;
2) operating personnel draws the position near ratchet carriage with square slider on the bar, tightens fixedly square slider by fastening bolt, delivers to the stockbridge damper bolt position by action bars, and ratchet carriage is inserted in the stockbridge damper nut;
3) the rotating operation bar is unscrewed fastening bolt slide block is moved to the groove afterbody of ratchet spanner, promotes action bars back and forth along line direction then and makes the ratchet spanner swing, and ratchet carriage rotates with the interlock of stockbridge damper bolt, the purpose of realization stockbridge damper bolted.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, whether fastening work does not receive the time and has a power failure to influence.
2, be applicable to the single, double loop line road operation of 110 kilovolts of-220 kilovolts of transmission lines.
3, reduce operating personnel's labour intensity, reduce the personnel operation fault rate, the fail safe that has improved operating personnel and equipment.After operating personnel's rod-rising tower is in place, carry out fastening work with regard to ratchet fastener on the available action bar.
4, Work tool reduces, without the lower wire operation, and the several times of can increasing work efficiency.
Description of drawings:
Fig. 1,2 is for the front view of ratchet spanner of the present invention, vertical view; Fig. 3 is socketed on the front view on the pinch bar for slide block among the present invention and locking member thereof, and Fig. 4 is the right view of slide block and locking member thereof among Fig. 3; Fig. 5 is the process chart that action bars cooperates with fastener.
Label among the figure: 1 ratchet carriage, 2 grooves, 3 slide blocks, 4 fastening bolts, 5 caging bolts, 6 boring nuts, 7 action bars.
Below pass through embodiment, and combine accompanying drawing that the present invention is described further.
Embodiment:
Embodiment: combine Fig. 1-5, the stockbridge damper bolt tightener, it comprises:
Ratchet spanner; Its front end is provided with ratchet carriage 1; On the handle of ratchet spanner, be provided with strip groove 2 along its length, the inner chamber of slide block 3 through its hollow is socketed on the handle of ratchet spanner and can on handle, slides, for the sliding stroke to slide block carries out spacing; Anti-limited slip block comes off from handle, is being provided with the caging bolt 5 that in groove 2, passes on the slide block 3.
