Description
Technical field
The present invention relates to a kind of power maintenance tool, more particularly to a kind of insulator section replacing device and replacing options.
Background technology
Insulator chain is responsible for the suspension wire and vital task to tower insulation, be transmission line of electricity visual plant it
One.Once insulator chain is damaged, it is necessary to change in time.There is pulling force between each sub-pieces on insulator chain, if
Sub-pieces are changed, it is necessary to first lay down the pulling force suffered by sub-pieces to be replaced.Existing sub-pieces are more
Method is changed, is to connect closed fixture respectively at sub-pieces both ends to be replaced, hydraulic screw rod, hydraulic pressure is connected on two closed fixtures
Leading screw is gradually shortened, and lays down the pulling force in sub-pieces, so as to remove sub-pieces and changed.This substitute mode one
It is secondary to carry out monolithic replacing, it is less efficient.
The content of the invention
It is less efficient in the presence of prior art it is an object of the invention to overcome the shortcomings of, there is provided one kind can be carried out
The insulator section replacing device and replacing options that sub-pieces segmented is changed.
In order to realize foregoing invention purpose, the invention provides following technical scheme:
A kind of insulator section replacing device, including first end assembly, middle part shackle member, load component and tensile elements,
Load component includes pulley and drawstring, and pulley is connected with middle part shackle member, and drawstring one end is connected with first end assembly, and drawstring is another
One end is connected around pulley with tensile elements, and tensile elements can pull drawstring, so as to apply middle part shackle member by middle part shackle member
The pulling force of first end assembly is pointed to, first end assembly and middle part shackle member are used to be connected to one section of insulator to be replaced
Both ends.
The first end assembly and middle part shackle member of insulator section replacing device provided by the invention are used to be connected to treat
The both ends for the one section of insulator changed, apply pulling force to load component by tensile elements.Due on load component include pulley and
Drawstring, by the effect of pulley, the drawstring positioned at pulley both sides can transmit and bear pulling force, so that putting on middle part
The pulling force that shackle member is subject to can be several times as much as the pulling force that tensile elements apply to drawstring, tensile elements is disclosure satisfy that insulator segmented
The needs of replacing.
