Utility model content
The utility model is for Problems existing in above-mentioned existing power transmission lines overhauling and checking process, there is provided a kind of can convenient working personnel from the ladder shape shape instrument not injuring synthetic insulator under cross-arm to wire, thus solve existing 220 kilovolts and Above Transmission Lines and cause because synthetic insulator is longer operating personnel cannot directly from the difficult problem to wire under cross-arm.
The technical solution of the utility model is as follows:
Synthetic insulator Simple crawling ladder, it comprises Simple crawling ladder grapple, and Simple crawling ladder grapple lower end is fixedly connected with Simple crawling ladder lifting and tunable arrangement, and Simple crawling ladder lifting and chain place, tunable arrangement lower end are fixedly connected with the mobile jib of Simple crawling ladder.
Described Simple crawling ladder lifting and tunable arrangement are circular, are provided with chain and the spanner for adjusting chain length.
Described chain is wound around and is arranged on Simple crawling ladder lifting and tunable arrangement, and described spanner is movably set in the middle part of the lifting of described Simple crawling ladder and tunable arrangement.
The mobile jib of described Simple crawling ladder is rod shape, and the foot nail being provided with Simple crawling ladder straggly, lower end is provided with the wire hook of the Simple crawling ladder that can catch on wire.
The beneficial effects of the utility model are as follows:
The utility model is applied in 220 kilovolts of Above Transmission Lines replacing synthetic insulators and operating personnel's synthetic insulator carries out checking to wire clamp and changes, drop into little, cost is low, lightweight, application is convenient, under cross-arm, to wire, do not trample synthetic insulator when operating personnel can be helped on tower to carry out upkeep operation, and chain block can be substituted carry out Insulators and suspension clamp is changed, reach the effect of one-object-many-purposes.And use and easy for installation; synthetic insulator Simple crawling ladder material of main part is irony or steel; and the different pulling force born according to different electric pressure and select the material of respective diameters and specification, thus the intensity of the instrument of guarantee, the safety of protection operating personnel and equipment.This Simple crawling ladder is provided with on the straight line pole of synthetic insulator at overhead transmission line and applies, effect one is that two ends can be hung on steel tower cross-arm and wire, thus play the effect of cat ladder and convenient working personnel by under cross-arm on wire, two be Simple crawling ladder itself with the adjusting device being similar to chain block, wire can be lifted by crane, shorten the distance of wire and cross-arm, load transfer, thus can change cross-arm be connected with wire between synthetic insulator, play the hard terraced double action that tradition changes chain block that the composite insulation period of the day from 11 p.m. to 1 a.m uses and lower wire, help line maintenance personnel inspection, change synthetic insulator, suspension clamp, and can not because trampling, scratching synthetic insulator and Insulators causes into damage, reduce circuit fortune inspection personnel and change the number of tools required for the composite insulation period of the day from 11 p.m. to 1 a.m, facilitate operating personnel's Insulators on tower, wire clamp, the inspection of wire and other annexes and maintenance, meet science, practical, economic principle, and reduce the damage of Insulators, ensure that the safe and reliable operation of circuit.
And the utility model is applied in 220 kilovolts of Above Transmission Lines replacing synthetic insulators and operating personnel's synthetic insulator carries out checking to wire clamp and changes, drop into little, cost is low, lightweight, application is convenient, under cross-arm, to wire, do not trample synthetic insulator when operating personnel can be helped on tower to carry out upkeep operation, and chain block can be substituted carry out Insulators and suspension clamp is changed, reach the effect of one-object-many-purposes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state schematic diagram of the present utility model.
In figure, 1, Simple crawling ladder grapple, 2, Simple crawling ladder lifting and tunable arrangement, 3, the mobile jib of Simple crawling ladder, 4, the foot nail of Simple crawling ladder, 5, the wire hook of Simple crawling ladder, 6, wire.
Embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of synthetic insulator Simple crawling ladder, it comprises Simple crawling ladder grapple 1, Simple crawling ladder grapple 1 lower end is fixedly connected with Simple crawling ladder lifting and tunable arrangement 2, Simple crawling ladder lifting and chain place, tunable arrangement 2 lower end are fixedly connected with the mobile jib 3 of Simple crawling ladder, Simple crawling ladder grapple is used for hooking cross-arm, cat ladder is connected with the wire below synthetic insulator with the cross-arm above synthetic insulator with hook by upper and lower grapple, there are adjustable apparatus and the upper and lower cat ladder of convenient working personnel in centre, two, cat ladder top grapple is mainly used for the cross-arm hooked above synthetic insulator.
