Description

A kind of double angle hanging point is changed the instrument and the method for wire jumper string
Technical field
The present invention relates to the technical field of power transmission sequence maintenance, relate in particular to instrument and method that a kind of double angle hanging point is changed the wire jumper string.
Background technology
At present, the single loop strain tower adopts mostly does the font tower, the drainage wire jumper string hanging point of this tower adopts double angle as shown in Figure 1 mostly, and the replacing method of this insulator wire jumper string adopts the palm cucurbit to change at present mostly, adopts the palm cucurbit to change some problems of depositing in practice.
Change the problem that exists with the palm cucurbit:
1, change the operation of need rolling off the production line of insulator wire jumper string with the palm cucurbit, drainage insulator wire jumper string is different with the insulator on the lead not to have tension force effect poor stability, and operating personnel's balanced capacity on line is poor, inefficiency.
2, the wire jumper insulator string that will prevent dust is changed compound wire jumper insulator string, also needs with about the rope ladder, and also there is potential safety hazard in inefficiency.
3, cooperate the lifting of steel wire cover with the palm cucurbit, easily cause the distortion of hanging point angle bar, zinc pull-up to fall, influence the whole stressed and erosion resistance of cross-arm.
4, because drainage thread does not have the tension force promptly can be with the insulator pull-up with the circulation coaster, overlap fixed block with steel wire, because the steel wire cover is respectively reserved the grafting length of 300mm by the security regulations two ends, the stressed back of the inconvenience that is fastened and steel wire loop easily elongation is caused apart from the insulator hanging point far away, can't colligation on the cross-arm in the effective range of lifting, though there is imagination seldom to use at present.
Summary of the invention
Based on change the problem that the wire jumper insulator string exists in real work, the invention provides a kind of double angle hanging point and change the instrument and the method for wire jumper string, personnel's manufactured without inserting winding can be finished more changing jobs of insulator in changing wire jumper insulator string process, improved operating speed, reduced task difficulty, the operating efficiency of changing the wire jumper insulator string is increased substantially.
For achieving the above object, the present invention adopts following technical scheme:
A kind of double angle hanging point is changed the instrument of wire jumper string, comprise: jig, fixedly jackscrew, ring-type screw, hanging point angle bar, circulation coaster, described jig is " U " letter stencil, " U " letter stencil both sides constitute one with the right angle flap respectively, two right angle flap symmetries, and be provided with the connecting hole with the ring-type screw, the ring-type screw passes connecting hole and jig is fixed by nut, and the annulus of ring-type screw links to each other with circulation coaster 5.
A kind of double angle hanging point is changed the method for wire jumper string, and its step is as follows:
1, the double angle hanging point being installed and being changed the wire jumper string tool, is that the jig that the double angle hanging point is changed the wire jumper string tool is installed on the tower bar double angle hanging point, fixes with jackscrew, and fixes with the ring-type screw of an end band; Hang the circulation coaster on the screw ring of the ring-type screw that the jig bottom connects, make the circulation coaster near apart from double angle hanging point distance;
2, the cross-arm maintainer will tear the endless rope colligation open on second porcelain vase of wire jumper insulator string on the tower;
3, colligation finishes, and the cooperation personnel spur rope under the tower, and insulator is not stressed, and personnel take the insulator top that links to each other with hanging point on the tower, and the wire jumper insulator string is fallen on the lead cross-arm together with drainage thread;
4, personnel remove the wire jumper insulator string bottom that links to each other with drainage thread down on the tower to lead cross-arm place, and the wire jumper insulator string of removing is fallen earthward;
5, the new wire jumper insulator string of changing is installed, move the wire jumper insulator string of newly changing to the cross-arm place with the endless rope colligation, load onto the wire jumper insulator string bottom that links to each other with drainage thread, spur endless rope subsequently and move insulator to ground wire cross-arm hanging point place, wire jumper insulator string top loaded onto with the hanging point bulb be connected, finish the replacing of drainage insulator wire jumper string.
A kind of double angle hanging point is changed the method for wire jumper string, the described wire jumper insulator string and the wire jumper insulator string that draws high new replacing that falls dismounting, or adopt and carry out simultaneously, the wire jumper insulator string colligation that to newly change on the ground is good, utilize the wire jumper insulator string weight of the dismounting of falling, the wire jumper insulator string that cooperates manpower newly to change is raised to lead cross-arm place, and the wire jumper insulator string of pulling down is fallen earthward.
Because adopt aforesaid technical scheme, the present invention has following superiority:
1) application of the present invention, cross-arm angle bar force way when having changed the insulator replacing, stressed to change face into stressed with former single-point centralized load, avoided the distortion of cross-arm angle bar, guaranteed the cross-arm overall mechanical strength, improve safety factor of workers, improved the safe operation of electrical network.
2) adopt the application of operational method of the present invention and instrument, substituted the operational method that former steel wire rope sling is hung the palm cucurbit, overcome with the steel wire cover difficulty inconvenient and that need roll off the production line because of colligation position distance is installed.
3) with palm cucurbit operational method, need the circulation coaster to cooperate endless rope equally, also need to transmit steel wire cover and palm cucurbit with endless rope, use this instrument can shorten the distance of circulation coaster apart from the string hanging point that dangles, personnel's manufactured without inserting winding promptly can be finished the colligation to insulator on the realization tower on cross-arm, overcome with steel wire cover difficulty inconvenient and that need roll off the production line because of colligation position distance has been installed, adopt this operational method to simplify working procedure, reduced construction tool, improved the coefficient of safety of operating efficiency and work high above the ground, reduce the transport difficulty of poor transport area instrument, reduced labour intensity.
4) the present invention not only be fit to shown in figure one downward the installing and using in double-angle iron hanging point plane, also be applicable to shown in figure two double-angle iron hanging point plane installing and using up.
5) adopt this method not to be only applicable to dust-proof insulator and change dust-proof insulator, also be suitable for common insulator replacing dust-proof insulator and dust-proof insulator replacing and meet insulator.
6) tool construction of the present invention is simple, and is easy to use, and processing and fabricating is easy, and production cost is lower, is easy to apply.
