Problems solved by technology

The traditional operation method mainly has the following problems: 1. When the double-split conductor is lifted, the connecting plate is tilted and shifted due to lack of support. It is difficult to restore the position of the insulator when the connecting plate is in such a state, which requires high technical level of the operators. And there are certain safety hazards; 2. The operation is difficult, the staff work for a long time, and the labor intensity is high; 3. When the wire lifter lifts the wire, it is easy to cause serious wear and tear of the wire and broken strands due to friction between the wire and the wire lifter. and other phenomena

Embodiment Construction

[0015] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 and figure 2 As shown, the special wire lifter for double-split wires of the present invention includes a wire lifter body 1 for replacing insulators of double-split wires. Specifically, the wire lifter body is designed as a left-right symmetrical structure, which can be easily manufactured. The end of the wire lifter body 1 is provided with a wire support hook 2 for supporting the wire, and the inside of the wire support hook 2 is provided with a rubber pad, which can reduce wear on the wire. The middle part of the wire lifter body 1 is connected with a steering joint 3 through a connecting bolt 4 . Pulleys (not shown in the figure) are also arranged on the thread lifter body 1. Specifically, the number of pulleys is two, and the two pulleys are arranged in the vertical direction. The pulleys are set on the thread l...

Abstract

The invention belongs to the technical field of electric power operation and maintenance equipment, and particularly relates to a special conductor lifting device for double-bundled conductors. The special conductor lifting device comprises a conductor lifting device body adopting a bilaterally symmetrical structure, wherein conductor supporting hooks are arranged at ends of the conductor lifting device body, rubber pads are arranged on inner sides of the conductor supporting hooks, the middle of the conductor lifting device body is connected with a steering joint through connecting bolts, the conductor lifting device body is connected with connecting plate supporting frames through two triangular connecting frames, the two connecting frames are parallel to each other, each connecting frame is connected with one connecting plate supporting frame, each connecting plate supporting frame comprises an adjusting screw rod, one end of each adjusting screw rod is connected with the corresponding connecting frame, the other end of each adjusting screw rod is connected with a Y-shaped supporting plate, and a pulley is arranged on the outer side of the conductor lifting device body. The special conductor lifting device has the advantages that connecting plates can be supported, workers can use the device conveniently, and the conductors can be effectively protected.

Description

technical field [0001] The invention belongs to the technical field of electric power operation and maintenance equipment, and in particular relates to a special wire lifter for double-split wires. Background technique [0002] Split conductor refers to a conductor erection method adopted by EHV and UHV transmission lines to suppress corona discharge and reduce line reactance, that is, each phase conductor is composed of several sub-conductors with smaller diameters, and each sub-conductor is separated by a certain distance And arranged in a symmetrical polygon, it can play the role of increasing the diameter of the wire. Compared with the large wire with the same total cross-section, it is not easy to generate corona and has a higher power transmission capacity. Split conductors are mainly used on transmission lines with a voltage level of 220kV and above. my country's 220kV transmission lines use double-split conductors. [0003] The double-split wire insulator needs to b...
