Abstract
The utility model relates to a wire extraction device for wire clamp maintenance, which comprises a clamp provided with a vertical groove in the middle, housings mounted on two sides of the clamp through supporting rods, and a wire extraction screw rod; shaft seats with internal threads are mounted in the housings; external threads matched with the internal threads on the shaft seats are set on the wire extraction screw rod; and a wire hook is arranged at the lower end part of the wire extraction screw rod. The wire extraction device can be fixed through the clamp, and the clamp can be conveniently fixed at the multiple parts of the wire clamp or a steel tower; moreover, when the wire extraction device is fixed, the ground wire can be built on stilts so long as the wire extraction screw rod is screwed on.
Description
Technical field
The utility model relates to a kind of line lifter of using when keeping in repair wire clamp, the line lifter of using when particularly keeping in repair the overhead ground wire wire clamp.
Background technology
Ground wire is to be used for electric current is introduced the lead of the earth.The power supply ground wire is to draw backbone after transformer neutral point ground connection, generally speaking, and every 20-30 rice iterative earthing, circuit is played the safeguard protection effect.The top of ground wire is by wire clamp that it is built on stilts, and the lower end requires the resistance value of earth electrode to approach zero by being connected with buried earthing device to form earth electrode.Because ground wire is to the influence to it of the draw of the wire clamp of overhead ground wire and external environment, mechanical deformation and chemical corrosion can take place after using a period of time in wire clamp, so the incident of maintenance wire clamp takes place often.
Yet, when maintenance or replacing wire clamp, for avoiding taking place electric shock accidents, need ground wire is built on stilts.In the prior art, the parts of overhead ground wire comprise the fixedly wooden rod member and the pulley or the assembly pulley that are suspended on this wooden rod member of certain altitude, ground wire is hung, treat again ground wire to be put back to after the binding clip maintenance is finished or changed by the suspension hook on pulley or the assembly pulley.Though the parts structure of this kind overhead ground wire is simple relatively, because when keeping in repair or change wire clamp, fixing wooden rod member is very difficult with hanging pulley or assembly pulley, not only labour intensity is relatively large, and operating efficiency is low.
Summary of the invention
The line lifter of using when the purpose of this utility model provides a kind of maintenance wire clamp of can handled easily and increasing work efficiency.
The line lifter of using during maintenance wire clamp that the utility model proposed comprises that the middle part is provided with the anchor clamps of vertical slot and is installed in the housing of these anchor clamps both sides by pole, tapped axle bed is installed in housing, and carry the line screw rod, this carry on the line screw rod be provided with axle bed on the external screw thread that is complementary of internal thread, carry line screw rod bottom at this wired hook be set.
The upper area of the sidewall of described anchor clamps is provided with through hole and inserts the interior alignment pin of this through hole.Described housing is upper and lower surfaces open rectangular frames, is respectively arranged with the recessed groove of a downward extension at the upper top of two relative sidewalls of this rectangle frame; Described axle bed has an external surface shape and size and the cuboid that shell inner surface shape and size are complementary, and is respectively arranged with the position-limiting ear that can extend in the recessed groove in the both sides of this cuboid.The described upper end of carrying the line screw rod is equipped with screws handle.
The line lifter of using during maintenance wire clamp that the utility model proposed is by the fixing line lifter of anchor clamps, and anchor clamps can be fixed on a plurality of positions on wire clamp or the iron tower easily, after line lifter is fixed, as long as screw carry the line screw rod can ground wire is built on stilts, so, operation is very easy to adopt this line lifter overhead ground wire, and operating efficiency is higher relatively.
Description of drawings
Accompanying drawing 1 be the utility model propose the maintenance wire clamp time embodiment of line lifter that uses the surface structure schematic diagram;
Embodiment
Referring to Fig. 1 and Fig. 2, the overall appearance structure of an embodiment of line lifter who uses when these two accompanying drawings provide the maintenance wire clamp that the utility model proposes.This line lifter comprises anchor clamps 1, housing 2, axle bed 3 and carries line screw rod 4.Anchor clamps 1 comprise a rectangle plate 11, and the open so that vertical slot 12 that wire clamp can insert below rectangle plate 11 thickness directions are provided with is provided with through hole and inserts alignment pin 13 in this through hole at the upper area of the sidewall of rectangle plate 11.Be separately installed with two poles 14 and 15 that are used for support housing 2 on two sidewalls of rectangle plate 11.Housing 2 is upper and lower surfaces open rectangular frames 21, is respectively arranged with a recessed groove 22 that extends downwards at the upper top of two relative sidewalls of this rectangle frame 21.Axle bed 3 has an external surface shape and size and housing 2 inner surface configurations and the big or small cuboid 31 that is complementary, be respectively arranged with the position-limiting ear 32 that can extend in the recessed groove 22 in the both sides of this cuboid 31, axle bed 3 vertically be provided with through hole, the inwall of through hole is provided with internal thread 33.The outer surface of carrying line screw rod 4 be provided with axle bed 3 on the external screw thread 41 that is complementary of internal thread 33, wired hook 42 is set in the bottom of carrying line screw rod 4, the end is equipped with and screws handle 43 thereon, handle 43 is screwed in rotation can make line hook 42 move the side downward or upward, hook ground wire with line hook 42, thereby ground wire is broken away from or the wire clamp of packing into.
