Description
Technical field
The utility model belongs to power industry, charged for replacement 220kV transmission line linear string bunch of insulator tool device technical field of structures.
Background technology
At present, domestic charged for replacement 220kV straight line bunch of insulator is changed the cross-arm jig adopted and is generally 2 cross-arm cards and combines.Because electric power line tower structure is different, tower is different, former cross-arm cannot normally use after being stuck in the installing of multiple tower, as: excessive because bearing pulling force, cause cross-arm tower material to be out of shape; Because screw mandrel length is long, cause live wire and steel tower tower body distance deficiency after adjustment cross-arm jig installation position mentions wire, the serious threat person and device security.Even original cross-arm jig cannot normally be installed on some steel tower.Project development of " changing 220kV straight line bunch of insulator cross-arm jig " be the special cross-arm jig of charged for replacement 220kV linear string bunch of insulator, this jig is by scalable jig main body, screw mandrel, flexible handle and fastening means are formed, can be carried by single, install and remove easy, decrease Work tool carrying quantity, be applicable to various types of steel tower cross-arm, and agree with closely with cross-arm, stressing conditions is evenly good, fundamentally solve charged for replacement 220kV straight line bunch of insulator cross-arm card not general, available stress is little, the problems such as potential safety hazard is large, the work of charged for replacement 220kV straight line bunch of insulator is made to become safer, more stable, more convenient, operate simpler.
Summary of the invention
The utility model provides and a kind ofly can agree with the cross-arm jig of use with various tower, when specifically using, is placed on cross-arm by the jig assembled, adjust scalable part bolt, jig closely, is firmly contacted with cross-arm, and operating personnel's rotary screw rod, mentions wire.Simple, convenient, respond well.
The purpose of this utility model is achieved by the following technical solution:
A kind of charged for replacement 220kV linear string bunch of insulator cross-arm jig, the utility model is characterised in that, this device comprises flexible jig, screw mandrel, flexible handle and connecting rod; Wherein scalable jig comprises two pieces of symmetrically arranged clamps, and clamp comprises two pieces of base plates connected vertically and backup plate, is connected with two pieces of gussets between base plate and backup plate; Offer in the outside of clamp base plate for the link slot through screw mandrel, and be provided with screw hole in base plate link slot end, after adopting screw mandrel access link slot, adopt screw spacing to screw mandrel by screw hole; Junction button is provided with on the top of screw mandrel, junction button is arranged with flexible handle, connecting rod is connected with by connector in the lower end of screw mandrel, connector laterally offers link bolt hole, inserts the connecting hole A on connecting rod by the connecting bolt through link bolt hole and adopt screw mandrel to realize the adjustment of connecting rod length; Offer for the connecting hole B through retract bolt on the top of clamp backup plate; Retract bolt is adopted to be each passed through the connecting hole B of two pieces of clamps and with fastening nuts, to coordinate by retract bolt and nut the distance adjusting two pieces of clamps.
The connection of screw mandrel, connector and connecting rod all adopts prior art.
The beneficial effect using this instrument to carry out the work of charged for replacement 220kV straight line bunch of insulator is: 1, this jig can freely adjust flexible, makes it to be applicable to various types of cross-arm, and contacts with cross-arm tightr; 2, pulling force needed for all size span can be born when this jig uses; 3, original two cross-arm jigs are simplified into a set of light telescopic cross-arm jig, change the forced position of cross-arm, make the work of charged for replacement 220kV straight line bunch of insulator become more convenient, safer.
The utility model content is set forth further below in conjunction with Figure of description and embodiment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
See Fig. 1, Fig. 2, a kind of charged for replacement 220kV linear string bunch of insulator cross-arm jig, the utility model is characterised in that, this device comprises flexible jig 1, screw mandrel 2, flexible handle 3 and connecting rod 4; Wherein scalable jig 1 comprises two pieces of symmetrically arranged clamps 1.1, and clamp 1.1 comprises two pieces of base plates 1.2 connected vertically and backup plate 1.3, is connected with two pieces of gussets 1.4 between base plate 1.2 and backup plate 1.3; Offer in the outside of clamp base plate 1.2 for the link slot 5 through screw mandrel 2, and be provided with screw hole 6 in base plate link slot 5 end, after adopting screw mandrel 2 to access link slot 5, adopt screw 7 pairs of screw mandrels 2 spacing by screw hole 6; Junction button 8 is provided with on the top of screw mandrel 2, junction button 8 is arranged with flexible handle 3, connecting rod 4 is connected with by connector 9 in the lower end of screw mandrel 2, connector 9 laterally offers link bolt hole 9.1, inserts the connecting hole A 4.1 on connecting rod 4 by the connecting bolt 9.2 through link bolt hole 9.1 and adopt screw mandrel 2 to realize the adjustment of connecting rod length; Offer for the connecting hole B 1.6 through retract bolt 1.5 on the top of clamp backup plate 1.3; Adopt retract bolt 1.5 to be each passed through the connecting hole B 1.6 of two pieces of clamps 1.1 and fastening with nut 1.7, coordinate by retract bolt and nut the distance adjusting two pieces of clamps.
