Description
Technical field
The utility model relates to the power station hydraulic turbines to repair field, i.e., after axial-flow Kaplan runner bucket connection bolt is killed
Taking-up tool.
Background technique
In the prior art, axial-flow Kaplan turbine runner dismounting maintenance belongs to complexity, risk, technical difficulty
Very big work easily causes the damage of personnel and equipment.Rotary wheel of water turbine is ZZ560-LH800 axial-flow Kaplan runner, is turned
Wheel is mainly made of components such as blade, web, pivot, pivoted arm, piston cylinder, crosshead, draft cones, runner totally 4 blades, often
9 fixing bolts of a blade, blade fixing bolt are M120*390.It is repaired in work in the expansion of all previous unit, occurred three respectively
Turbines vane bolt kills phenomenon, takes the process of bolt extremely complex, and time consumption is more, and the most serious is once No. 1 machine
During expansion is repaired, is killed there are two bolt, take the bolt used time 23 days, seriously affect the unit maintenance duration.Taking-up is killed bolt and was operated
Cheng Zhong also easily causes personnel, equipment injury, to find out its cause, being that tool is not professional, rigidity is insufficient, and positioning is inaccurate.To prevent in not
So, manufacture and design a set of bolt and take out tool, in case of need.
Utility model content
The purpose of this utility model is in view of the above deficiencies and provides a kind of axial-flow Kaplan that laborsaving time saving safety is handy
Runner bucket connection bolt takes out tool after killing.
The technical solution of the utility model is: axial-flow Kaplan runner bucket connection bolt takes out tool after killing,
It is characterized by comprising a set of adjustable fixings and the bench drill milling machine being fixed on adjustable fixing；Adjustable fixing
Including the immobilizing foundation plate being fixedly connected with pivot and the adjustable trestle being connect with immobilizing foundation plate；Drilling and milling machine with bore library and
Drilling tool (drill bit, lathe tool or milling cutter).
Immobilizing foundation plate is plectane, is circumferentially equipped with 12 screw bottom outlets by the setting of connection bolt orientation, and confession is adjustable
Bracket positioning, corresponding blade connection bolt carry out position and fix, and mode bracket bottom plate is correspondingly provided with screw hole, on base plate not
Screw bottom outlet with position connects.
The utility model has the advantages that: 1, this tool operation easy, greatly reduces the investment of human and material resources, shortens
Blade connection bolt takes out the maintenance duration of work after killing.It simplifies blade connection bolt and kills rear removal method, be suitble to complete
The similar turbines vane connection bolt of state takes out work after killing.2, it economic benefit: by using this specific purpose tool, does not need to turn
Wheel body carries out returning factory and office's reason or is transported to the processing of big machinery processing factory or external coordination machining Chang Ru factory and office reason, saves a large amount of
Equipment processing cost transports large scale equipment traffic expense and cooperation processing personnel's One-Shift Costs, save take out kill screw when
Between, increasing unit can be using hourage, above several total more than 10 ten thousand yuan of saving.3, safety benefit: this specific purpose tool is used
Afterwards, simple because designing, installation is facilitated, reduces installation and operator, reduces the generation of personal injury thing.Due to this
Specific purpose tool adjustability and (can fill drill bit, lathe tool and milling cutter) vdiverse in function makes to take out and kills screw accurate positioning, is not susceptible to
Rotatable parts burst apart, and have prevented the generation hurted sb.'s feelings that flies out to apparatus body damage and component.4, social benefit: make suitable for all
Taking-up work is killed with axial-flow Kaplan and bulb through-flow turbine runner bucket bolt, after being killed for blade bolt, is taken out
Tool making provides a kind of feasible, reliable solution, has vast promotional value.
The embodiments of the present invention is described in further detail below in conjunction with attached drawing.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is base plate structure diagram.
Specific embodiment
Referring to Fig. 1,2, parts title is as follows: adjustable fixing 1, pivot 2, base plate 3, adjustable trestle 4, bores milling
Bed 5, special jewel library 6, drill bit 7, blade connect bolt 8, screw bottom outlet 9.
Referring to Fig. 1, axial-flow Kaplan runner bucket connection bolt takes out tool, including a set of adjustable fixing after killing
1 and a Miniature drilling-milling machine 5 being fixed on adjustable fixing 1；Adjustable fixing 1 includes being fixedly connected with pivot 2
Immobilizing foundation plate 3 and the adjustable trestle 4 being connect with immobilizing foundation plate 3；Drilling and milling machine 5 is with library 6 and drilling tool 7 is bored, such as drill bit, vehicle
Knife or milling cutter.The present apparatus is used to take out work after killing blade connection bolt 8.
Referring to fig. 2, immobilizing foundation plate 3 is plectane, is circumferentially equipped with 12 screw bottom outlets by the setting of connection 8 orientation of bolt
9, it is positioned for adjustable trestle 4, corresponding blade connection bolt 8 carries out position and fixes.4 bottom plate of mode bracket is correspondingly provided with screw
Hole is connect with the screw bottom outlet 9 of different location on base plate 3, adjustment is realized, convenient for connecting bolt 8 with the blade of different location
It is corresponding, work is taken out after being killed.
After the blade connection bolt 8 that blade is killed first is removed bolt head with gas welding, blade is removed, pivot is leaked out and stings
Dead blade connects bolt 8.Immobilizing foundation plate 3 is connect with adjustable trestle 4, it is with bridge machine that adjustable fixing 1 is whole solid
It is scheduled on runner pivot 2, adjustable fixing 1 is fixedly connected securely with drilling and milling machine 5, loads onto and bore library 6 and drilling tool 7(drill bit),
Blade connection bolt location is pressed on adjustment adjustable trestle 4(base plate 3 and is equipped with 12 screw bottom outlets, by adjusting adjustable branch
Frame 4 fixes position, can correspond the blade connection bolt 8 killed), so that drilling and milling machine 5 is directed at the blade connection bolt 8 killed
Behind center, by 4 fixation of adjustable trestle.Start drilling and milling machine 5, is connected by the blade that one man operation drilling and milling machine 5 is killed
Bolt 8 takes out operation, can replace drilling tool 7(according to need of work in operation process and install lathe tool, milling cutter), complete the leaf killed
Piece connects bolt 8 and takes out operation.
It is described above, only specific embodiment of the present utility model, various illustrations are not to the reality of the utility model
The limitation of matter Composition of contents.
