The lifting device of the utility model has the beneficial effects that: the lifting device is formed through long-term work practice according to work experience for replacing the strain insulator of the power transmission line and characteristics of operation of the power transmission line, and has the advantages of convenient construction operation, simple and convenient fixation, simple operation, capacity for greatly raising labor intensity of operating personnel, and capacity for meeting the requirements of power-off maintenance works of a 110kV line; the lifting device of the utility model can reduce labor intensity of the operating personnel, shorten working time, raise working efficiency, and ensure personal safety of the operating personnel; in addition, the lifting device of the utility model completely overcomes the inconveniences to the operating personnel brought by the old working mode and tool for replacing the strain insulator.
Description
Technical field
The utility model relates to power industry Maintenance of Electric Transmission Line service kit, relates in particular to a kind of device for taking bottle that is convenient for changing the power line tension insulator.
Background technology
Employed in ultra-high-tension power transmission line at present have suspension insulator, strain insulator (vertical string) to have three kinds: porcelain insulator, glass insulator, compound inslation (silicon rubber) insulator.Electric pressure is: lOkV, 35kV, 110kV, 220kV, 330kV, several electric pressures of 550kV.Porcelain insulator, glass insulator are blocks of the compositions, are connected in series certain sheet number according to electric pressure when mounted; 110kV is a string to be 8, and 220kV is a string to be 15.Select than distance according to the creepage of electric pressure.Compound inslation (silicon rubber) insulator is overall structure, waters in a string and outpours several cluster parachutes, and is creepage than apart from requiring with what reach the associated voltage grade.Can often change strain insulator in the high-altitude during maintenance of power industry Maintenance of Electric Transmission Line, one secondary strain insulator weighs tens kilograms, traditional mode is three people operations, it is on the hanging point on porcelain vase or the tower bar that one people is responsible for that a end with strain insulator hangs on the cross-arm, two people are responsible for bearing a heavy burden, and also installation is fixing for strain insulator, old instrument and working method make operating personnel's physical demands huge, and installment work time length is also brought certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of bottle lifter for tension insulators of power transmission line that is convenient for changing insulator is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bottle lifter for tension insulators of power transmission line, it is characterized in that: the end by the tubing of circular steel tubulose connects the first fixed support, the other end of tubing connects the second fixed support and consists of, the first fixed support lower end has an energy lock ring also can to press from both sides along the arc lock ring that wire slides on the maintenance wire, the upper lower clamping piece two ends of arc lock ring folder are connected and fixed by bolt, the second fixed support is a leg-of-mutton fixed support, the second support bracket fastened underframe is by bolt and the fixing lock ring folder that forms of another intermediate plate, be provided with side plate at the first fixed support, between side plate and fixed support, three root posts are set at least, the curved arrangement of three root posts.
Above-mentioned bottle lifter for tension insulators of power transmission line evenly is provided with the ring muscle on column.
Adopt technique scheme, the utility model has following advantage: according to transmission line change the working experience of strain insulator and Research Work of Power Transmission Line characteristics, form through long-term working practice, has construction operation convenient, fixing easy, simple to operate, improved greatly operating personnel's labour intensity, can satisfy the requirement of 110kV line outage upkeep operation; Use neoteric device for taking bottle, can alleviate operating personnel's labour intensity, shortened the operating time, improved operating efficiency, guarantee operating personnel's personal safety.The working method of old replacing strain insulator and the inconvenience that instrument brings to the operating personnel have been overcome fully.
Description of drawings
Fig. 1 is structural representation of the present utility model.
