Description
Technical field
The present invention relates to a kind of homework of supplying power device, particularly relate to a kind of even mode Multifunctional sleeve.
Background technology
Distribution uninterrupted operation is using gradually as the major way of State Grid Corporation of China's urban distribution network upkeep operation.According to " distribution wire
Road livewire work fire protection technology " regulation, distribution network live line work one is divided into 3 classes: the first kind (insulating bar working system) is repaiied
Poll, removing foreign body, dismounting used facilities and common defect elimination, breaking and connecting fuse switch goes between, and wiring is propped up in breaking and connecting
Pass line；Going between on Equations of The Second Kind (insulating glove working system) breaking and connecting fuse switch, link lead-in wire is propped up in breaking and connecting,
Change linear rod insulator；3rd class (insulating bar working system) changes linear rod insulator, and group is vertical or removes straight-line wire pole.
Hard work amount brings high requirement to the configuration of Work tool, and therefore the development of specialized live working tools is imperative.
Bolt involved in the middle of distribution line and transmission line of electricity and screw rod are of a great variety, only hex bolts just have from Φ 10mm to
15 kinds of Φ 302mm.Bolt and the kind of screw rod that first kind livewire work relates to have 3 kinds, and Equations of The Second Kind livewire work relates to
To bolt and the kind of screw rod have 4 kinds, bolt and the kind of screw rod that the 3rd class livewire work relates to have 4 kinds, and more than
Data be also not included in tearing open old during the erose bolt screw rod that seriously formed of the corrosion met.
The most it is not applicable to the Work tool of case above, only pipe wrench and can tentatively meet regulation various sizes bolt spiral shell
The function of bar, but pipe wrench size is relatively big, cannot meet the requirement that livewire work movement range is little in use.Carry out the most every time
Work is intended to prepare a series of sleeve barrel tool.And a set of conventional set sleeve barrel tool and spanner nearly weigh greatly 5 kilograms, carry and use
All will bring sizable physical consumption to operating personnel.
Summary of the invention
For the problems referred to above of the prior art, the present invention proposes a kind of even mode Multifunctional sleeve, to be applicable to distribution wire work
