Portable live line working line lifter
Technical field
The utility model relates to power construction utensil, is specially a kind of portable live line working line lifter.
Background technology
Along with the continuous construction and development in electric power barrier, old outmoded circuit also gets more and more, incident is the service work relevant with wire and ground wire grown with each passing day, the such as installation of icing supervisory control system, the work such as hitch point displacement, suspension clamp replacing, ground wire repairing.
The repair method generally used now is by coaster, Lever Blocks, the first-class lifting carrying out having turned to overhead ground wire of steel wire rope, not only inefficiency, and considerably increase the time of staying on shaft tower, meanwhile also add the potential safety hazard in work; In addition, use the all-metal Work tools such as Lever Blocks due to said method, and hanging point is more, the requirement of live line working cannot be met.
Utility model content
For the deficiencies in the prior art, technical problem to be solved in the utility model be propose a kind of can efficient in the charged situation of circuit, portable live line working line lifter that safety completes maintenance.
The portable live line working line lifter that can solve the problems of the technologies described above, its technical scheme comprises lifting device, difference is that described lifting device comprises the elevating mechanism and insulation pulling plate that are made up of the screw mandrel mutually screwed and nut, described elevating mechanism is located on the cantilever of jig side, the lower end of the upper end connection wire rod of described insulation pulling plate, the lower end conducting wire hook of insulation pulling plate, the moving runner of rotary screw rod is installed in the upper end of described screw mandrel; Described jig to be installed on the angle steel at cross arm of tower place by draw-in groove and to use bolt fixed position, and described draw-in groove is inwardly vertically offered bottom jig.
The utility model is for current shaft tower type, through the research repeatedly to shaft tower profile, find that all there is angle steel at cross arm of tower place, utilize angle steel as screens point design jig, based on elevating mechanism, insulation pulling plate and wire hook that jig design is made up of feed screw nut, by the charged lifting lead wire of the leading screw of elevating mechanism and ground wire, and no longer need with uncontrolled all-metal Work tools such as Lever Blocks, effectively ensure that the safety of live line working is carried out.
A kind of plan of establishment of described elevating mechanism: described screw mandrel is placed in the vertical groove on cantilever, arranges bayonet socket corresponding to groove position in the top of cantilever, and described nut clamps and is fixed in bayonet socket.
The preferred generation type of described groove is: groove is inwardly offered perpendicular to draw-in groove from cantilever side.
Driving-belt is conventionally adopted to rotate moving runner.
The beneficial effects of the utility model:
The utility model portable live line working line lifter mainly applies in the hotline maintenance work of daily transmission line, by jig, screw mandrel, nut and the assembly such as insulation pulling plate and wire hook, the wire of complete paired transmission line and the charged castering action of ground wire, thus meet when circuit does not have a power failure, complete the installation of icing supervisory control system safely and efficiently, the work such as hitch point displacement, suspension clamp replacing, ground wire repairing, effectively reduce interruption duration, improve power supply reliability.

Figure number identifies: 1, screw mandrel; 2, nut; 3, insulation pulling plate; 4, wire hook; 5, moving runner; 6, jig; 6-1, draw-in groove; 6-2, cantilever; 6-3, groove; 6-4, bayonet socket; 7, driving-belt.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the technical solution of the utility model is described further.
The portable live line working line lifter of the utility model, comprises elevating mechanism, insulation pulling plate 3 and wire hook 4 that jig 6, screw mandrel 1 and nut 2 are formed.
Described jig 6 (band steel can be adopted to be welded) is with double flute, one is draw-in groove 6-1 (slightly larger than angle steel width), for blocking the angle steel at cross arm of tower place and being fixed with bolt, another is groove 6-3, for installing elevating mechanism.
Described draw-in groove 6-1 is inwardly vertically formed from the bottom of jig 6, be triangle cantilever 6-2 on the right side of jig 6, described groove 6-3 is inwardly vertically formed in cantilever 6-2 right side central, groove 6-3 is mutually vertical with draw-in groove 6-1, the front and rear sides of groove 6-3 top cantilever arm 6-2 is provided with bayonet socket 6-4, as shown in Fig. 2 (a), Fig. 2 (b).
Described nut 2 clamps and is fixed between forward and backward bayonet socket 6-4, described screw mandrel 1 to be placed in groove 6-3 and to screw installation with nut 2, the upper end of screw mandrel 1 is stretched out jig 6 and is installed moving runner 5, described moving runner 5 holds driving-belt 7 is installed, the lower end of screw mandrel 1 is stretched out jig 6 and is connected with the upper end of insulation pulling plate 3, described wire hook 4 is arranged on the lower end of insulation pulling plate 3, as shown in Figure 1.
The utility model has the advantage of:
1, can carry out the work when circuit does not have a power failure, meet the requirement of live line working completely, effectively reduce interruption duration, improve power supply reliability.
2, structure is simple, and quality is light, and installation method is simple, can increase work efficiency.
3, improve the condition of work of transmission line workman, cater to the trend that following live line working increases increasingly, there is larger promotional value.
