Abstract
The invention relates to lifting gear with a concrete rod grounded downlead, which is characterized by comprising a ratchet wrench and a support column, wherein the support column is arranged in the ratchet sleeve of the ratchet wrench in a penetrating mode; and the support column is fixed with a winding wire rope and a lifting wire rope, the winding wire rope can wind on the concrete rod, and the lifting wire rope is used for lifting the grounded downlead. The upper end of the lifting gear winds the winding wire rope on the concrete rod, the lower end of the lifting gear is connected to the flat iron of the grounded downlead through the lifting wire rope, and the grounded downlead can be lifted by rotating the ratchet wrench. By using the lifting gear, one person can measure the resistance value of a ground net, thereby saving the human resources, enhancing the working efficiency and greatly reducing the labor intensity.
Description
Technical field
The present invention relates to the Maintenance of Electric Transmission Line instrument, particularly relate to a kind of lifting device of gear with concrete rod grounded downlead.
Background technology
Down conductor is the bare metal conductor that connects concrete bar body and buried ground network; Its effect is the resistance measurement of being convenient to ground network; And the resistance measurement of ground network is defeated line circuit operation and the main measuring quantifier order when checking and accepting, its measuring period according to electric pressure be 1～2 year once.
110kV～2200kV transmission line concrete rod type is mainly two bars; Must open a side (reservation opposite side) down conductor during measurement and measure, through after geology variation, the rain penetration, backfill soil takes place to sink circuit in running; Just can give downward pulling force of down conductor; After grounding nut was opened, down conductor just can sink, after grounding resistance measurement finishes; Because the height of down conductor descends, cause the bolt of down conductor can't recover (fastening) to original state.At present; Must two people carry out simultaneously when carrying out this work, promptly after measurement of Grounding Resistance finished, operating personnel made a call to a knot with thinner rope sling on the band iron of down conductor; Mention down conductor; Another operating personnel recover (fastening screw) down conductor, the time-consuming effort of taking a lot of work of the method, inefficiency.
Summary of the invention
The object of the invention just is to overcome the defective of above-mentioned prior art, provides a kind of and effectively increases work efficiency, and saves human resources, reduces the lifting device of the gear with concrete rod grounded downlead of labour intensity.
The present invention realizes through following technical proposals:
A kind of lifting device of gear with concrete rod grounded downlead; It is characterized in that: comprise ratchet spanner and support column; Support column is through in the ratchet carriage of ratchet spanner, be fixed with on the said support column can be on the concrete bar around steel wire rope and the boom hoist cable that is used to promote down conductor;
Above-mentioned ratchet spanner has two, is symmetrical set;
The end of above-mentioned boom hoist cable is provided with dop.
The lifting device upper end of gear with concrete rod grounded downlead of the present invention will be wrapped on the concrete bar around steel wire rope; The lower end is connected on the band iron of down conductor with boom hoist cable (or dop), just can down conductor be promoted through rotating ratchet spanner (tightening up steel wire rope).Use lifting device one people of the present invention just can accomplish the resistance measurement work of ground network, saved human resources, high efficiency, and greatly reduce labour intensity.
Description of drawings
Fig. 1 is the structural representation sketch of the lifting device of gear with concrete rod grounded downlead of the present invention;
Fig. 2 is the user mode sketch map of apparatus of the present invention.
Embodiment
The lifting device of gear with concrete rod grounded downlead of the present invention comprises two ratchet spanneres 1 and a support column 2 made from round steel; Support column 2 is through in the ratchet carriage of two ratchet spanneres 1 successively; Respectively weld an annulus 7 at the two ends of support column 2; The adjustment position is located at two ratchet spanner 1 symmetries and is fixed on the support column 2.The two ends symmetry perforating of support column 2 will be used to pass around steel wire rope 4, and each plays a glance about the center of support column 2 simultaneously, is used to pass boom hoist cable 6.During use; Buckle 9 around being installed with a wedge on the steel wire rope 4, will pass wedge again and buckle 9 knotting systems and drag for around the concrete bar 3 of walking around of steel wire rope 4, boom hoist cable 6 ends are provided with dop 10; Block with the band iron 11 of dop 10 the down conductor upper end; Rotating ratchet spanner 1 (tightening up steel wire rope) just can promote down conductor 5, and in the 8 corresponding last times of pole-footing screw on the screw 12 to the band iron 11 and the concrete bar, last nut is fastening to get final product.
