The beneficial effect of the utility model is; Can make insulating bar and hook form the angle structure through angle regulator; Hang on the line during use, under the action of gravity of earth connection, make between insulating bar and the earth connection also shape in an angle; Insulating bar can remain heeling condition and point operation personnel, thereby earth connection is separated with insulating bar.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said grounding assembly has two at least; Earth connection in wherein said each grounding assembly intersects at a point, and extends to form a total earth connection, and said total earth connection is connected with said grounded metal bar.
Further, said grounding assembly also comprises the earth connection termination, and an end of said earth connection termination is connected with said hook, and the other end of said earth connection termination is connected with said earth connection.
Further, the junction of said earth connection termination and said earth connection is provided with the anti-spring of losing.
Adopt the beneficial effect of above-mentioned further scheme to be, for preventing earth connection damage, the junction in earth connection and earth connection termination adds and prevents losing spring, utilizes the tension force of spring to control copper cash and the dead angle do not occur and breakage.
Further, said angle regulator comprises rail groove, maintenance axle and fixed screw, and said fixed screw is connected with said hook, and said maintenance axle is connected with said insulating bar, and said rail groove is connected with said maintenance axle.
Description of drawings
Fig. 1 is the structural representation of the utility model overhead transmission line maintenance with earthing device;
Fig. 2 comprises the structural representation of three grounding assemblies with earthing device for the maintenance of the utility model overhead transmission line;
In the accompanying drawing, the list of parts of each label representative is following:
1, hook, 2-1, fixed screw, 2-2, rail groove, 2-3, maintenance axle, 3, the earth connection termination, 4, earth connection, 5, the anti-spring of losing, 6, insulating bar, 7, the grounded metal bar.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1, earthing device is used in a kind of overhead transmission line maintenance, comprises grounding assembly and the grounded metal bar 7 that is connected with said grounding assembly, and said grounding assembly comprises hook 1, earth connection 4, insulating bar 6, angle regulator; One end of said earth connection 4 is connected with said hook 1, and the other end of said earth connection 4 is connected with said grounded metal bar 7, and said hook 1 is connected with said insulating bar 6 through said angle regulator.
Said grounding assembly also comprises earth connection termination 3, and an end of said earth connection termination 3 is connected with said hook 1, and the other end of said earth connection termination 3 is connected with said earth connection 4.Said earth connection termination 3 is provided with the anti-spring 5 of losing with the junction of said earth connection 4.
Said angle regulator comprises rail groove 2-2, maintenance axle 2-3 and fixed screw 2-1, and said fixed screw 2-1 is connected with said hook 1, and said maintenance axle 2-3 is connected with said insulating bar 6, and said rail groove 2-2 is connected with said maintenance axle 2-3.
As shown in Figure 2; Earthing device is used in a kind of overhead transmission line maintenance, comprises three identical grounding assemblies, and each assembly comprises hook 1, earth connection 4, insulating bar 6, angle regulator and anti-spring 5 compositions of losing; Insulating bar 6 and link up with 1 between be provided with angle regulator; Angle regulator is made up of rail groove 2-2, maintenance axle 2-3 and fixed screw 2-1, and earth connection termination 3 is fixedly installed on the hook 1, and 3 lower ends, earth connection termination are fixed with earth connection 4; Earth connection termination 3 is peripheral with earth connection 4 junctions; Be provided with anti-spring 5, the three winding ground wires of losing and intersect at a point and extend outward a total earth connection, total earth connection end is connected with grounded metal bar 7.
The concrete operation principle of the utility model is following:
During use, operating personnel are earlier with grounded metal bar 7 reliable grounds, adjustment hook 1 angle then, 2-1 fix through fixed screw, treat that the operator identifies the true no-voltage of maintenance circuit after, immediately with earth connection 4, link up with 1 and be hung on the overhead transmission line.When hanging earthing device, will link up with 1 as far as possible and push a distant place to.Because the special angle existence of the action of gravity of earth connection 4 and ground connection hook 1 design itself, the insulating bar 6 that is hung on the lead can remain heeling condition point operation personnel, earth connection 4 then vertically downward, away from operating personnel.
During dismounting, the operator holds insulating bar 6 tail down tight in one's hands on the other hand with defeating, and upwards firmly lift hand-held insulating bar 6 middle and lower parts of another, and earth connection 4 just is easy to break away from lead like this.After finishing using, can will link up with 1 through angle regulator and be adjusted to and insulating bar 6 same rectilinear directions, thereby help transportation and storage.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the utility model.
