Description
Technical field
The present invention relates to a kind of tower end load jig that is used for the live line working of power system high tension power line tangent tower.
Background technology
Traditional ultra-high-tension power transmission line tangent tower live line working tower end load jig adopts that the version structure of insulated hanger bar and cross-arm support is complicated, overall dimension is bigger.When being used for charged work high above the ground, for jig cross-arm support and insulated hanger bar are realized being connected, the operating personnel must penetrate the cross-arm support earlier from top to bottom on the tower in the two main material two angle-iron frame slits of lead hanging point, the cross-arm support is connected with insulated hanger bar bolt, personnel must be stretched in body part (hand) cross-arm master material below on the tower, finish a complete set of lead load device assembles, traditional power tool and operating type make the air gap between human body short circuit earth electrode and the electrified body, shortened the live line working safe distance, bring certain hazards for the safe operation of live line working operating personnel personal safety and transmission line charging equipment, and increased (high-altitude) work operations amount on the tower, the input manpower is more, operating time is longer, and efficiency descends thereupon.
Summary of the invention
Technical problem to be solved by this invention provide a kind of quick and easy for installation, safe and reliable can effectively increase work efficiency entirely be used for ultra-high-tension power transmission line tangent tower live line working tower end load jig.
The present invention adopts following technical scheme:
The present invention includes jig, jig leading screw, can drive leading screw lowering or hoisting gear that the jig leading screw moves up and down and the insulated hanger bar that is arranged on jig leading screw lower end.
Jig of the present invention both sides are provided with the jig wing plate, and the jig wing plate is provided with the reinforcement gusset.
The width of jig wing plate of the present invention is 40-60mm, and the optimum width of jig wing plate is 45-59mm.
The invention has the beneficial effects as follows: use the transmission of a complete set of load instrument of the present invention once to finish, avoid repeating work, reduce workload, reduce manpower, time input, increase work efficiency, method of operation of the present invention is easy, and practical function is obvious, can be applied to 110kV～500kV transmission line tangent tower live line working work.
The present invention is particularly useful for the contest of live line working technical ability.
Use the simplification of operating procedure of the present invention, can reduce the probability that the hazard events such as falling object from high altitude of instrument in transmittance process takes place, guarantee safety.Personnel need not be stretched in body part (hand) cross-arm master material below on the tower.The person and shielding clothing can the short circuit electrified body and earth electrode between the air gap.Guarantee charging equipment and personal safety, improve the job safety level.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
In the accompanying drawings: 1 jig, 2 jig leading screws, 3 jig wing plates, 4 are strengthened gusset, 5 leading screw lowering or hoisting gears, 6 iron tower main materials, 7 insulated hanger bars, 8 insulator strings, 9 leads, 10 hooks, 11 operating grips.
Concrete real examination mode
As shown in drawings, the present invention includes jig 1, jig leading screw 2, can drive leading screw lowering or hoisting gear 5 that jig leading screw 2 moves up and down and the insulated hanger bar 7 that is arranged on jig leading screw 2 lower ends.Jig of the present invention 1 both sides are provided with jig wing plate 3, and jig wing plate 3 is provided with strengthens gusset 4.The width of jig wing plate 3 of the present invention is 40-60mm, and the optimum width of jig wing plate 3 is 45-59mm.
Jig 1 of the present invention, jig leading screw 2 and insulated hanger bar 7 connect as one, be passed on the tower jig leading screw 2 bottom-up penetrating in hanging point iron tower main material 6 slits, treat that jig rises to hanging point iron tower main material 6 tops, personnel's rotary fixture 1 on the tower, make it evenly stressed on iron tower main material 6 leading role's steel, can tighten up leading screw lifting lead 9 and carry out operation.The width of jig wing plate 3 of the present invention is 40-60mm, and the optimum width of jig wing plate 3 is 45-59mm, and the spacing between the iron tower main material 6 is 60mm, can penetrate in the slit between the two main materials of 500kV ultra-high-tension power transmission line tangent tower lead hanging point like this.As shown in drawings, jig 1 of the present invention is of a size of 58 * 58 * 45mm.
Adopt the operating procedure of jig of the present invention as follows:
1, jig 1 of the present invention, jig leading screw 2 and insulated hanger bar 3 are connected on ground.
2, use jig 1, jig leading screw 2 and insulated hanger bar 3 integral body transmitted after rope will connect to be delivered on the tower.After adopting jig of the present invention, a complete set of stressed equipment can the disposable installation on ground, and stressed equipment can once be passed on the tower.
3, the width of jig wing plate 3 of the present invention is 40-60mm, the optimum width of jig wing plate 3 is 45-59mm, can make on the tower personnel auxiliary like this is bottom-up penetrating iron tower main material 6 slits (two main materials are that the spacing between the iron tower main material 6 is 60mm) with jig 1 and jig leading screw 2 from lead 9 hanging wire points pair main materials, when treating that jig 1 rises to iron tower main material 6 tops, jig wing plate 3 revolved turn 90 degrees, make it evenly stressed on iron tower main material 6.After adopting jig of the present invention, on the tower personnel hand need not to be extended cross-arm master material be iron tower main material 6 belows.Avoid the air gap between the person and shielding clothing short circuit electrified body and the earth electrode.Guarantee charging equipment and personal safety.Avoid required workload of repetitive operation and time.Jig of the present invention 1 both sides are provided with jig wing plate 3, and jig wing plate 3 is provided with strengthens gusset 4, can improve the bearing capacity of jig 1 greatly, makes jig 1 more sturdy and durable.
