Description

A kind of universal crossover sub for livewire work
Technical field
The invention belongs to power industry, a kind of specific purpose tool structure technology neck of charged for replacement 220kV straight line bunch of insulator Domain.
Background technology
At present, Work tool used in charged for replacement 220kV linear insulator chains is complete by ideal cross arm of tower and conducting wire It is complete to manufacture and design at an angle of 90, but cross-arm in actual motion equipment and the angle of conducting wire are not the right angle of standard, there is one Fixed differential seat angle.Work tool stress is undesirable in operation process, is easily damaged, and installation exercise tool is difficult, increases operating personnel Labor intensity in addition be unable to charged for replacement replacement, line outage can only be forced to and overhauled, increase operating risk, increase Equipment power off time seriously reduces the availability coefficient of equipment, reduces the reliability of power supply.
During charged for replacement 220kV linear insulator chains, using equipotential and ground potential combined techniques.Tool has:Lifting rope, Rope ladder frame, insulated flexible ladder, insulation pulling plate, insulation coaster, line lifter, screw etc..Due to the diversification of cross arm of tower, caused peace It is difficult to fill power tool, increases operating personnel's labor intensity, is even unable to charged for replacement.
Invention content
The purpose of the present invention is to overcome the problems of the above-mentioned prior art and design it is rotatable, can solve Cross-arm and conducting wire angle problem, the replacement that can be suitably used for all linear insulator chains, operating risk value are low, safe and reliable and time saving The specific purpose tool of labour-saving overhead transmission line replacing linear insulator string under electrification.The purpose of the present invention is pass through following technical side Case is realized:
A kind of universal crossover sub for livewire work, the invention is characterised in that, including under a upper connective plate and one Yoke plate;Connected between upper connective plate and lower linking plate by the nut segment thread fitting connected in the bolt section and lower linking plate of upper connective plate It connects, small screw hole M is offered in bolt section, small screw hole N is offered in nut segment, bolt section and nut segment spiral reach certain Position makes small screw hole M, small screw hole N form coincidence;It is screwed in the small screw hole after overlapping with bolt, prevents from loosening during use; The bolt section is set with one section of endoporus;
Nut segment is passed through when being equipped with intermediate axis connection in lower linking plate axial direction and is extend into the endoporus;
First line of a couplet hole is laterally offered on upper connective plate to connect with livewire work specific purpose tool insulation pulling plate, it is horizontal on lower linking plate It is connect to second line of a couplet hole is offered with livewire work specific purpose tool line lifter;
Between the nut segment and lower linking plate one is connected and composed by the bearing and lower linking plate that are fixed on jackshaft It is whole;Bearing is enable to make 360 ° of rotations around axial line, while bears corresponding pulling force.
The beneficial effects of the invention are as follows:The present invention can solve former charged for replacement 220kV linear insulator chains Work tool by The problem of power is undesirable, is easily damaged, and installation exercise tool is difficult, and operating personnel's labor intensity is big or even is unable to charged for replacement, It greatly improves work efficiency, operating risk value is made to reduce, is safe and reliable and time saving and energy saving, makes replacement transmission line of electricity linear string Upkeep operation is more standardized, standardization.

Specific embodiment
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of universal crossover sub for livewire work, the invention is characterised in that, including One upper connective plate 1 and a lower linking plate 4;By connecting in the bolt section 2 and lower linking plate of upper connective plate between upper connective plate and lower linking plate 3 thread fitting of the nut segment connection connect, small screw hole M is offered in bolt section 2, small screw hole N, spiral shell are offered in nut segment 3 Bolt section 2 and 3 spiral of nut segment, which reach certain position, makes small screw hole M, small screw hole N form coincidence;It is screwed in bolt 8 small after overlapping In screw hole 7, prevent from loosening during use;The bolt section 2 is set with one section of endoporus 10;
Nut segment 3 is passed through when being equipped with jackshaft 11 in 4 axial direction of lower linking plate and connecting and is extend into the endoporus 10;
It laterally offers first line of a couplet hole 9 on upper connective plate 1 to connect with livewire work specific purpose tool insulation pulling plate, in lower linking plate 4 Upper transverse direction offers second line of a couplet hole 6 and is connect with livewire work specific purpose tool line lifter;
Structure is connect with lower linking plate 4 by the bearing 5 being fixed on jackshaft 11 between the nut segment 3 and lower linking plate 4 Into an entirety;Bearing 5 is enable to make 360 ° of rotations around axial line, while bears corresponding pulling force.
The present invention is made of metal material, and can bear the working pulling force of daily 80KN, and maximum can bear the drawing of 200KN Power.
In livewire work, replace transmission line of electricity 220kV linear string bunch of insulator when, can only using equipotential with Ground potential combined techniques.Tool has:Lifting rope, rope ladder frame, insulated flexible ladder, insulation pulling plate, insulation coaster, line lifter, screw etc..Due to These Work tools are manufactured and designed, but with conducting wire in actual motion equipment at an angle of 90 completely by ideal cross arm of tower The angle of cross-arm and conducting wire is not the right angle of standard, there is certain differential seat angle.The present invention is reached with a crossover sub Change the effect of this angle, prevent in replacement process that Work tool stress is undesirable, be easily damaged, installation exercise tool difficulty etc. Problem.The present invention installs a crossover sub additional on tool, is used cooperatively with insulation pulling plate, during by equipotential electrician's installation operation It is more time saving and energy saving.After specific purpose tool use of the present invention, the labor intensity of equipotential live line work personnel can be reduced, greatly shortens operation Time, so as to fulfill the risk reduced during operating personnel's Equipotential live working.
2. tool materials, structure technology require
Material is 40 aluminum alloy materials of LuCr-60, φ, and surface is smooth and carries out preservative treatment, and live load is 80kN, bearable load 200kN safety coefficient are 2.5 times.
