Further, described first arc hoop plate is provided with the first mounting ear, and the first mounting ear is provided with half slot, and the second arc hoop plate is provided with the second mounting ear; Detachable fastener is made up of secondary stepped stem and handle, and secondary stepped stem is made up of minor diameter part and large-diameter portion, and minor diameter part diameter is identical with half slot width size, and minor diameter part is by screw thread switching on the second mounting ear, and handle is fixed on large-diameter portion.Be convenient to the installation and removal of detachable fastener.
Further, described first arc hoop plate is fixed on pedestal, or the first arc hoop plate and pedestal are wholely set, or the switching of the first arc hoop plate is on pedestal.
Further, described insulation cross bar is hollow section.Alleviate the weight of insulation cross bar, decrease labour intensity.
Further, described insulation cross bar is expansion link.Be convenient to the length of the spacing adjustment insulation cross bar according to two wire jumpers.
Further, rubber pad is equipped with on each first arc hoop plate inside wall He on each second arc hoop plate inside wall.Be conducive to reducing the wearing and tearing to wire jumper.
Compared with prior art the utility model has the advantages that: in the utility model, some eradication edge cross bars are arranged on two bar lines by detachable fastener and form step ladder, be arranged on wire jumper by a section for insulation cross bar in the process of swashing towards equipotential, when getting off, a section cross bar to be disassembled; Climbing is convenient, reduces risk and the labour intensity of staff; Staff does not need along two insulator strings, and according to " trick synchronous horizontal moves " of " short by three across two " technical requirements, when solving that in prior art, two insulator string spacing are more than 60cm, staff passes in and out the problem of equipotential difficulty.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of cross bar and mount pad in the utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the location diagram of the utility model and shaft tower.
Detailed description of the invention
Consult Fig. 1 and Fig. 2, a kind of insulation step ladder, the insulation cross bar 2 comprising two wire jumpers 1 and be arranged between two wire jumpers 1, often thoroughly do away with two ends on edge cross bar 2 and be all fixed with mount pad 3, each mount pad 3 include be fixed on insulation cross bar 2 on pedestal 4, first arc hoop plate 5, second arc hoop plate 6 and detachable fastener 7, first arc hoop plate 5 is arranged on pedestal 4, second arc hoop plate 6 is transferred on pedestal 4, and the first arc hoop plate 5 and the second arc hoop plate 6 are held tightly on wire jumper 1 by detachable fastener 7.Described first arc hoop plate 5 is provided with the first mounting ear 8, first mounting ear 8 and is provided with half slot 81, and the second arc hoop plate 6 is provided with the second mounting ear 9; Detachable fastener 7 is made up of secondary stepped stem 10 and handle 11, secondary stepped stem 10 is made up of minor diameter part and large-diameter portion, minor diameter part diameter is identical with half slot 81 width size, and minor diameter part is by screw thread switching on the second mounting ear 9, and handle 11 is fixed on large-diameter portion.Described first arc hoop plate 5 is fixed on pedestal 4, or the first arc hoop plate 5 is wholely set with pedestal 4, or the first arc hoop plate 5 is transferred on pedestal 4.Described insulation cross bar 2 is hollow section.Described insulation cross bar 2 is expansion link.Rubber pad 12 is equipped with on each first arc hoop plate 5 inside wall He on each second arc hoop plate 6 inside wall.
During work, when mount pad 3 is arranged on wire jumper 1, first by the first arc hoop plate 5 and the second arc hoop plate 6 armfuls on wire jumper 1, the minor diameter part of secondary stepped stem 10 is connected in half slot 81 simultaneously, by rotary handle 11, first mounting ear 8 and the second mounting ear 9 are drawn close gradually, the large-diameter portion of secondary stepped stem 10 is limited on the first mounting ear 8, thus mount pad 3 is arranged on wire jumper 1.
