Description
Technical field
The present invention relates to the combination removal tool and method for dismounting of a kind of generator stator bar and headgear, belong to hair
Motor stator service technique field.
Background technology
The stator bar of generator is evenly distributed on the inside of the silicon steel sheet of generator unit stator, is embedded in and is superimposed by multilayer silicon steel sheet
Slot wedge in；Simultaneously headgear includes upper and headgear and lower and headgear to stator, is made up respectively of copper metal material, boring tin in top layer is in silver
Grey, their effect is will to entangle and weld to connect together above and below stator bar joint, is led so that bar is concatenated to be formed
Logical coil.
The stator maintenance of generator, either changes stator bar, or processing bar joint poor flow etc.
Problem, it is necessary to first by bar and head partial demolition.And head portion includes the metal of outermost epoxy insulation box and internal layer
And headgear.Remove the metal of internal layer and during headgear with conventional method, be that first it is heated at high temperature with heating tool, make it and
Soldering adhesion part fusing between bar, then adds flat chisel to carry out shovel and hits and the auxiliary side with the artificial withdrawing of locking pliers with hammer again
Formula will be removed simultaneously headgear.
This traditional method for dismounting has two：
（1）Operation is dangerous：Removed with traditional method, high temperature and headgear and splash melting welding slag easily cause
Human body is scalded；Simultaneously because bar joint belongs to red copper metal material, soft pliable at high operating temperatures, and this method for dismounting meeting
Make and headgear unbalance stress, the impaired deformation of bar joint can be caused.
（2）Operating efficiency is low：This work needs two people to coordinate progress, and closely people works under the simultaneously headgear condition of high temperature
Industry, personnel are nervous.And simultaneously headgear bite position is not known, it is difficult to firmly, construction speed is slow, or even occur because could not
Impact in time is extracted and causes to repeat scorification, is more taken time and effort.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of simple in construction, use operation side
Just, person scald and the impaired deformation of bar can be effectively prevented, significantly shortens maintenance duration, while significantly improving and headgear dismounting work
Make efficiency, effectively the generator stator bar of release labour and the combination removal tool of headgear and method for dismounting.
The purpose of the present invention is following technical scheme to complete, and the combination of a kind of generator stator bar and headgear is removed
Instrument, described bar and headgear include upper and headgear and lower and headgear, and the combination removal tool includes being respectively used to remove

It is connected in the upper neck of joint below simultaneously headgear；Be inserted in the described upper axis of guide one can in the upper axis of guide on move down
Dynamic upper movement arm hammer；Hammered on described above platform and be further fixed on handle on one；
Described lower and headgear remover includes a lower axis of guide, and the upper end of the lower axis of guide is fixed with a disk
The banking stop of shape, bottom, which is fixed with, hammers platform, and the bottom of the lower hammering platform is fixed with lower bayonet slot operating head, at this
Perpendicular be provided with the top center of lower bayonet slot operating head can be connected in down the lower bayonet slot of joint below simultaneously headgear；The described lower axis of guide
In be inserted in one can be moved up and down in the lower axis of guide lower movement arm hammer；One is further fixed in the lower hammering platform side
Lower handle.
In of the present invention upper and headgear remover, upper movement arm hammer for head upward, sub- tinkling of pieces of jade shape hollow circular cylinder,
Described upper handle is metallic rod shaped handle, and its outer end is provided with flexible glue taper knob；The upper card of the upper neck operating head
It is that can easily be caught in the bell mouth shape of joint below simultaneously headgear at channel opening；
In described lower and headgear remover, lower movement arm hammer for head is directed downwardly, sub- tinkling of pieces of jade shape hollow circular cylinder, it is described under
Handle is metallic rod shaped handle, and its outer end is provided with lower flexible glue taper knob；At the lower bayonet slot opening of the lower bayonet slot operating head
Can to be easily caught in the bell mouth shape of joint below simultaneously headgear, the bottom of lower bayonet slot operating head is provided with headgear in the lump and held
Groove, and it is each provided with before and after the containing tank a piece of baffle plate.
It is a kind of to carry out the method that generator stator bar and headgear are removed, the method for dismounting using the combination removal tool
Removed including upper and headgear and lower and headgear two aspects of dismounting, wherein：
The upper and headgear method for dismounting comprises the following steps：
a）Artificial left hand holds handle, and the right hand holds movement arm hammer, remover is placed in the top of simultaneously headgear, shape
Remover posture is controlled into stable balance；
b）By the lower section joint of the upper simultaneously headgear of the upper neck flare openings alignment of upper neck operating head, upper neck is grasped
The upper neck for making head is caught in and joint below headgear；
c）Left hand is held with a firm grip upper handle, and the right hand puts upper movement arm hammer to bottom；Upper movement arm of holding with a firm grip is hammered into shape, shock of having an effect upwards
Upper hammering platform, multiple impact are until successfully get upper and headgear；
d）The upper and headgear of high temperature is poured onto to the home specified；
Described lower and headgear method for dismounting comprises the following steps：
a）Artificial left hand holds lower handle, and the right hand holds lower movement arm hammer, remover is placed in down to the top of simultaneously headgear, shape
Remover posture is controlled into stable balance；

Under have an effect the lower hammering platform of shock, multiple impact is until successfully get upper and headgear；And got moment in lower and headgear, the right hand
The top that lower movement arm hammer is fixed on rapidly the lower axis of guide is held, remover is balanced, but now lower bayonet slot operation rostral is in
It is angled slightly downward state；
d）The upper and headgear of high temperature is poured onto to the home specified.
The present invention has the following technical effect that：
（1）Removed using specific purpose tool and during headgear, during operation human body and high temperature and headgear maintains enough distances
And security standpoint, neck operating head and containing tank blocked melting welding slag spluttering, and the high temperature pulled down and headgear are stably stayed in
In containing tank, it is to avoid personal scald；When removing specific purpose tool using upper and headgear, staff brandishes movement arm hammer and hit upwards
Hammer hits platform, and axis of guide transmission of the impact through being connected under platform averagely, is stably acted on by neck and on headgear,
Uniform force, it is ensured that bar joint stands intact；When removing specific purpose tool using lower and headgear, staff brandishes movement arm
Hammer slamming down hammering platform into shape, impact directly averagely, is stably acted on by platform and neck and on headgear, equally reached
Uniform force, it is ensured that bar joint intact effect；
（2）Specific purpose tool only needs one can easy manipulation；When in use, as long as staff holds with a firm grip instrument to do hammering dynamic
Make 2 to 5 times, you can quick to remove the high temperature through fusing and headgear, dismounting is time-consuming significantly to be shortened.Compared to traditional dismounting
Method, the net cycle time conversion consumed using specific purpose tool gets up to shorten 3/4ths.
