Description
Technical field
The present invention relates to a kind of hot line maintenance auxiliary device, the lifting of a kind of large-tonnage live wire
Device.
Background technology
In recent years, the most perfect along with electric network composition, 500kV transmission line of electricity progressively increases, along with carrying of conveying capacity
Height, mode of movement is divided in the many employings of wire more, and line footpath also synchronizes to strengthen, thus causes the increase of shaft tower vertical load.Meanwhile,
The path of general 500kV transmission line of electricity is many through mountain area, owing to the shaft tower between two hilltops crosses over distance relatively greatly, causes wire shelves
Away from increase, the vertical load of shaft tower is made to strengthen further.In the ordinary course of things, the shaft tower bigger to bearing vertical load, for carrying
The weight capacity of high insulator chain, all considers double insulator string hang during design.Secondly 500kV transmission line of electricity is to crossing over weight
Want facility, such as power circuit, the military and important communication of highway, railway, high ferro, river, 110kV and above

Submode, its vertical load up to 6.5 tons and more than, as used conventional Work tool livewire work, because Work tool allows load not
Meet to promote and require and livewire work cannot be realized.
If 2 by strengthening the load of lifting Work tool, its metal tools will increase lifting tonnage, then certainly will be heavy,
Thus strengthen the difficulty of operator, it is unfavorable for job safety, increases operating risk.Simultaneously to insulation hoisting tool, realize
The biggest loading promotes, and all brings bigger difficulty in design and manufacture.
3, not being plane owing to cross-arm head is many, during hot line job, the bending resistance of insulant, anti-twisting property are more weak, so
Raised position is proposed high requirement, it is impossible to the most arbitrarily use according to the requirement of power failure operation, to promote big loading simultaneously and bear
Carry, insulant mechanical strength it is difficult to ensure that.
4, to the lifting weight livewire work more than more than 5 tons, in operation process, the insulation standby fallen at anti-wire is protected
Protect in measure, there is presently no the insulant of such performance.
Analyze according to above, need to study a kind of new lifting operational method and Work tool, to promote large-tonnage wire,
And realize promoting and back-up protection integration, change the defect elimination work such as 500kV insulator chain in the case of solving big loading.It is correlated with and carries
The equipment of liter need to reach easy and simple to handle, and Work tool is installed simple, thus improves the risk control of livewire work and work high above the ground, reduces
The labor intensity of operating personnel, strengthens the safety of operation, and this case is given birth to therefrom.
