Abstract

The invention discloses a fixture for spacers of 500-kilovolt power transmission lines and a method for disassembling the spacers. Operational inspection and maintenance and defect elimination on the spacers which are important protective fittings for the power transmission lines are critical work for maintaining safe and stable operation of the power transmission lines, faults such as collision of conducting wires and strand breakage of the conducting wires can be possibly caused if defects of the spacers are not timely eliminated by the aid of live operation or power-off maintenance operation, and safe operation of the lines can be severely threatened. The fixture for the spacers of the 500-kilovolt power transmission lines comprises a lead screw (1), an upper spacer clamp (2) and a lower spacer clamp (3). The upper spacer clamp and the lower spacer clamp respectively sleeve the positions close to the middle of the lead screw, the upper end of the lead screw is connected with a ratchet wrench (4), a spacer ratchet fixture (5) is arranged in a circular through hole of the ratchet wrench, an upper and lower spacer clamp positioning rod (6) is arranged between the upper spacer clamp and the lower spacer clamp in a connected manner, and a lead screw wrench (7) is inserted in a through hole in the lower end of the lead screw. The fixture and the method are mainly applied to power transmission lines.

Description

500 KV transmission line conductor spacer fixture and assembly and disassembly methods
The present invention relates to a kind of 500 KV transmission line conductor spacer fixture and assembly and disassembly methods, be quickly accomplished between defect Every more changing jobs of rod, significantly shorten the working time of livewire work, improve work efficiency and the safety of livewire work Performance.
Background technology:
As the important protection gold utensil of transmission line of electricity, the operational inspection of conductor spacer and maintenance defect elimination be safeguard transmission line of electricity safety, The key job of stable operation.If utilizing livewire work or interruption maintenance operation to eliminate the defect of conductor spacer not in time, may Cause the faults such as wire whiplash, wire strand breakage, run to line security and cause serious threat.
At present, the defect processing conductor spacer all uses the method removed old part, install new part, mainly has following two to work Pattern:
For individual defects, livewire work is utilized to complete more changing jobs of conductor spacer;
For the centrality problem such as product quality, ageing equipment, utilize interruption maintenance plan, to transmission line of electricity all fronts or a certain district More changing jobs of Duan Jinhang conductor spacer.
But, by with in the engineerings such as transmission line equipment detail design, overhaul technological transformation, it is respectively adopted different design lists Position, unit in charge of construction and manufacturer, cause power transmission line spacer pattern, model in fortune various, even same or same The conductor spacer of different types, model is there is on transmission line of electricity in span.For installation and the replacing of different model conductor spacer, fortune Dimension unit would generally design, customized, purchase corresponding different types of conductor spacer fixture, the production that improve service work becomes This.During the upkeep operation of 500 KV transmission line conductor spacers, operating personnel need to carry multiple difference according to task The conductor spacer fixture of type carries out stepping on the upkeep operation such as tower, cabling, adds complexity and the labor intensity of upkeep operation, fall The safety coefficient of low upkeep operation and work efficiency.
Summary of the invention:
It is an object of the invention to provide a kind of 500 KV transmission line conductor spacer fixture and assembly and disassembly methods.
Above-mentioned purpose is realized by following technical scheme:
A kind of 500 KV transmission line conductor spacer fixtures, its composition includes: block under card and conductor spacer on leading screw, conductor spacer, described Leading screw be inserted in respectively on described conductor spacer under card and described conductor spacer near middle position and block, described leading screw Upper end is connected with ratchet spanner, is provided with conductor spacer ratchet fixture, described interval in the manhole of described ratchet spanner On rod, card blocks location bar up and down with the conductor spacer that is connected with of card under described conductor spacer, and the through hole of the lower end of described leading screw is inserted into There is leading screw spanner.
The assembly and disassembly methods of 500 described KV transmission line conductor spacer fixtures, the method comprises the steps:
By ratchet spanner, conductor spacer ratchet fixture with degree of tightness conductor spacer bolt, with fixture from as the arm of force, to complete between dismounting Work every rod;On conductor spacer, under card, conductor spacer, card, leading screw, conductor spacer block location bar up and down and leading screw spanner is respectively leading screw Formula conductor spacer fixture, wherein blocks under card and conductor spacer on conductor spacer
Represent the upper card of screw type conductor spacer fixture and lower card respectively, blocked bar fixed position, location, work by conductor spacer up and down Time by rotational lead screw spanner, loosen, tighten leading screw to adjust the upper and lower card of conductor spacer, block and wring conductor spacer support arm, to help and to take Pin down or at installation interval rod support arm, is quickly completed dismounting conductor spacer work.
Beneficial effects of the present invention:
1. existing different types of conductor spacer fixture function is merged by the present invention, it is achieved that multiple types changed by single fixture The design object of type conductor spacer, ratchet-type conductor spacer fixture and the use experience of screw type conductor spacer fixture, for tool construction Carry out appropriate design, and by the test of transmission line of electricity work on the spot and improvement, effectively by ratchet-type conductor spacer fixture and silk The function of thick stick formula conductor spacer fixture merges.
The function of ratchet-type conductor spacer fixture and screw type conductor spacer fixture is merged by the present invention, and structure is simplified, model machine weight 1.5kg, and traditional ratchet-type conductor spacer fixture and screw type conductor spacer fixture always weigh about 5kg.Therefore the design subtracts effectively Weigh 70% so that just carry with operating personnel in actual service work, be effectively reduced the labor intensity of upkeep operation, promote The work effect of upkeep operation and security performance.Meanwhile, the economic performance that power transmission line spacer more changes jobs is promoted.
The present invention is tested in being worked by actual field, and this project achievement is convenient for carrying, simple to operate, is suitable for and O&M list Fortune more the changing jobs of conductor spacer in the administrative circuit in position, operating personnel during upkeep operation without changing conductor spacer fixture, The work efficiency of 500 KV transmission line conductor spacer upkeep operations is promoted more than 2 times, can be widely 500,000 through demonstration Volt power transmission lines overhauling work is promoted and uses.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the left view of accompanying drawing 1.
