Abstract
The invention discloses a wire lifting device for replacing a plus and minus 800 kilovolt electric transmission line composite insulator string in a charged mode. The wire lifting device comprises a wire grip and an insulation pull rod connected with the lower end of the wire grip. The lower end of the insulation pull rod is connected with a wire lifting component. The wire lifting component comprises a clamping connector and a connecting board, wherein the clamping connector is connected with the upper end of a linkage board; the upper end of the connecting board is used for being connected with the insulation pull rod. The upper end of the linkage board connecting the insulator string and a guide line is clamped by the U-shaped clamping connector, the connecting board at the upper end of the clamping connector is in clamped connection with the insulation pull rod, and the wire grip connected with the upper end of the insulation pull rod drives the insulation pull rod to move upwards, so that the linkage board ascends through motion transferring, and the insulator string is replaced after being loosened. One wire lifting assembly replaces two heavy six-wire lifting hooks, a fastener directly penetrates through connecting holes in the upper end of the linkage board and the wire lifting assembly for fastening, and then six wires can be lifted. The wire lifting device has the advantages of being simple in structure, and easy, rapid and convenient to operate, and the safety of personnel working high above the ground is improved.
Description
Technical field
The present invention relates to the replacing insulator string instrument on a kind of transmission line, be specifically related to a kind of line apparatus of carrying of changing ± 800 kilovolts of straight line list V string composite insulators.
Background technology
The line components of carrying of changing at present ± 800 kilovolts of straight line list V string compound inslation period of the day from 11 p.m. to 1 a.m adopts six line thread-lifting hooks, be clipped in the both sides of yoke plate and be connected with it with two six line thread-lifting hooks, the upper end of six line thread-lifting hooks connects respectively insulation pull-rod, insulation pull-rod is connected with hydraulic line tightening system, drive insulation pull-rod up to move by hydraulic line tightening system, thereby will on yoke plate, carry, make insulator string lax, then carry out follow-up replacing insulator string operation.This defect of putting forward two aspects of line structure existence: be the complex structure of six line thread-lifting hooks on the one hand, the time-consuming material that takes of processing and fabricating, increase cost, the weight that is on the other hand single six line thread-lifting hooks is just large, also need two six line thread-lifting hook docking, each dog hole is aimed to wire, and complicated operation, brings very large potential safety hazard to work high above the ground personnel.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, simple to operate line apparatus of carrying, change safely and efficiently ± 800 kilovolts of straight line list V string composite insulators.
This charged for replacement ± 800 disclosed by the invention KV transmission line composite insulator string carry line apparatus, comprise wire grip and be connected in the insulation pull-rod of its lower end, the lower end of insulation pull-rod is connected with carries line components.The described line components of carrying comprises that the clamping joint that is connected with yoke plate upper end and clamping joint upper end are for connecting the connecting plate of the pull-rod that insulate.
Described clamping joint is u shaped connector, and there is the notch of indent at its length direction center, has the through hole vertical with notch, notch to block after yoke plate and connect by the securing member through its two side through hole on the entity of notch both sides.
The connecting hole of two through-thickness is arranged at described connecting plate top, and two connecting holes are about the length direction center line symmetry of connecting plate.
Described insulation pull-rod has two, and its lower end is U-shaped draw-in groove, has the through hole of Vertical U-type draw-in groove on its two side entity, insulate between pull-rod and described connecting plate by being connected through the securing member of through hole and described connecting hole.Between two insulation pull-rods, there is angle, mutually vertical between pulling force face between the lifting plane forming between two pull-rods and two insulator strings, and adopt 90 degree conversions to promote, stressed having avoided of connecting plate concentrated, can relatively reduce on the one hand the thickness of connecting plate, alleviate its weight, can also expand on the other hand operating space, improve safety in utilization.
Described wire grip is oil cylinder, and described insulation pull-rod is connected in the piston-rod lower end of described oil cylinder.
Operation principle of the present invention is as follows: by U-shaped clamping joint, the yoke plate upper end of connecting insulator string and wire is clamped, connecting plate by clamping joint upper end is connected with insulation pull-rod, drive insulation pull-rod up to move by the wire grip being connected with insulation pull-rod upper end, thereby transmit and make yoke plate increase by motion, change operation after making insulator string lax.
Carry line components with one and replaced two six heavy line thread-lifting hooks, directly promote through yoke plate upper end and fastening six lines of can realizing of connecting hole of carrying on line components with securing member, the troublesome operations having promoted together again after having avoided existing employing six line thread-lifting hooks that each root wire is hooked, there is simple in structure, simple and quick advantage, operating process is shortened greatly, improved work high above the ground personnel's fail safe.
