Description
Technical field
It the utility model is related to a kind of a kind of assembly and disassembly work of draft tube cone under mounting or dismounting tools, more particularly to bottom dismantling type hydraulic turbine
Tool.
Background technology
Bottom dismantling type structure is a kind of important arrangement form of the hydraulic turbine, this structure can in the case of generator is not dismantled,
To lower leakage stop ring of hydraulic turbine, runner, base ring and stator etc., some flow passage components easy to wear carry out inspection and maintenance, can greatly save
Repair time.The advantages of due to bottom dismantling type structure, more and more it is applied to Francis turbine, pump-storage generator now
With the turbine-generator units on more silt particle rivers.
Torn open under before the consumable accessorys such as lower leakage stop ring of hydraulic turbine, runner, it is necessary to draft tube cone under first dismantling, now upper tail water cone
Pipe and draft tube elbow installation site are motionless, and the lower axially adjustable gap of draft tube cone is smaller, can not use traditional driving or electronic
Cucurbit lifting, the horizontal mode pulled out.
Chinese patent 201320861968.4, a kind of hydraulic turbine horizontal mixed flow runner mounting or dismounting tools, the assembly and disassembly work are disclosed
Tool includes support bar, and one end termination of the support bar is provided with adapter sleeve, is provided with and props up in the rear end of the adapter sleeve
The slip cap of strut connection, contiguous block is provided with the outer wall of the slip cap, and band nut is provided with the contiguous block
Jack-up stud.This structure can not meet existing required performance, operate relative complex.
Utility model content
The utility model mainly solves the deficiencies in the prior art, there is provided a kind of compact-sized degree is high, with jack-up
The lower flange plate of draft tube cone under stud pull-up, and fixed with nut；Lower draft tube cone is removed after slide rail installation to bore with upper tail water
The attachment bolt of pipe, lower draft tube cone can put down 2mm or so, when ensureing lower draft tube cone movement, thereon, lower flange face and upper tail
Water cone pipe and draft tube elbow flange face disengage, and the instrument coordinates chain block to use, and time saving and energy saving, simple in construction and cost is low
The mounting or dismounting tools of draft tube cone under a kind of bottom dismantling type hydraulic turbine.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
The mounting or dismounting tools of draft tube cone under a kind of bottom dismantling type hydraulic turbine, including lower draft tube cone, described lower draft tube cone
Top be provided with upper draft tube cone, the bottom of described lower draft tube cone is provided with draft tube elbow, described lower draft tube cone lower end
Outer wall be provided with lower flange plate, the jack-up stud extended downwardly is provided with described lower flange plate, described jacks up under stud
End is provided with slide plate, and the back of described slide plate outer end is provided with slide rail, and described slide rail carries out displacement along guide rail.
Preferably, described jack-up stud is positioned by adjusting nut and the regulation of lower flange plate, described slide plate top
Outer end be provided with suspension ring, described slide plate is bolted with slide rail.
Preferably, the spacing between described lower draft tube cone and draft tube elbow is 8mm.
Preferably, described guide rail is fixed with draft tube elbow.
During installation, lower attachment bolt between draft tube cone and draft tube elbow is first removed；With jacking up stud by lower draft tube cone
Lower flange pull-up 8mm, and fixed with nut；Slide rail is placed on guide rail, the lower draft tube cone of dismounting couples with upper draft tube cone
Bolt, then lower draft tube cone is put down, it is disengaged 2mm with upper draft tube cone；Chain block one end is fixed on tail water machine
On the basis of cheating exit, other end connection suspension ring, slowly lower draft tube cone is hauled out to tail water machine along guide rail and cheats outlet.By upper
Reversely behaviour can complete the installation of lower draft tube cone to face step.
The utility model provides a kind of mounting or dismounting tools of draft tube cone under bottom dismantling type hydraulic turbine, compact-sized, lifting operation
Performance.
