Description
Technical field
The utility model belongs to large-size machine mounting technique, and in particular to the pumping of Large Rotor wears specific purpose tool.
Background technique
When carrying out large-size machine pumping now, wearing the work of rotor, the tool of use includes L-type dummy shaft, suspender, overhead traveling crane, tool
Body method is: L-type dummy shaft is installed first on rotor；It is affixed on the outside of L-type dummy shaft bottom end and rotor that dummy shaft and rotor is made to become one
Body structure, top cross-bar are suspended from the surface for outside motor stator and being in rotor, lifting point are arranged on crossbeam；Take out/wear construction
The preceding position for needing to adjust lifting point on dummy shaft crossbeam, enables lifting point to be overlapped with rotor c.g.；After leveling, day garage is utilized
Vehicle is taken out, wears rotor.
Existing this mode, which takes out, wears rotor has the disadvantage in that
(1) rotor c.g. must be accurately looked for, and needs to keep a close eye on gap of the rotor in bore of stator in lifting,
It avoids colliding with mutually between motor stator and rotor when taking out, wearing rotor, damages motor.
(2) this mode also relies on the tight fit between staff and overhead traveling crane driver, if mismate, is easy damage
Bad motor.
(3) when taking out, wearing rotor and proceed to half, if it find that gap is too small, center of gravity adjusting has deviation, can not be in process
In secondary carry out that center of gravity is looked for work.
(4) when taking out, wearing rotor, only rotor side is lifted by crane, stability is poor.
Utility model content
To solve problems of the prior art, the utility model provides a kind of steady when can be improved pumping, wearing rotor
Qualitative and safety reduces the construction tool special of the risk of damage equipment when taking out, wearing rotor.
To achieve the above object, technology official documents and correspondence provided by the utility model is:
A kind of large-size machine is taken out, wears rotor specific purpose tool, it includes the dummy shaft being fixedly mounted on rotor, the dummy shaft packet
Include the first dummy shaft, the second dummy shaft；First dummy shaft and rotor left end are affixed, and length is equivalent to rotor length, and the first dummy shaft is hung
Decorate setting end to the left；Second dummy shaft and rotor right end are affixed, its right-hand end is arranged in the lifting point of the second dummy shaft；Also
Horizontal shore is set including moving door frame, at the top of moving door frame, sets that there are three chain blocks on horizontal shore；Positioned at two sides
Chain block is connect with the first dummy shaft, the second dummy shaft respectively, is located in the middle hand-held cucurbit equipped with hanging belt；Hanging belt works as rotor
When extraction section is far beyond its position of centre of gravity, it is mounted on the rotor.
The utility model can effectively improve pumping, stability and safety when wearing rotor, reduce damage when taking out, wearing rotor and setting
Standby risk.
Detailed description of the invention
Fig. 1 is in the prior art for taking out the structure for wearing rotor；
Fig. 2 the utility model structure；
Fig. 3 is preliminary installation diagram；
Fig. 4 is largely to extract rotor out state；
Fig. 5 is installation hanging belt state diagram；
Fig. 6 is that rotor is fully drawn out state.
In figure, rotor 1, stator 2, dummy shaft 3, the first dummy shaft 31, the second dummy shaft 32, moving door frame 4, horizontal shore 5, hand
Draw cucurbit 6, hanging belt 7.
Specific embodiment
The technical solution of the utility model is described in detail below with reference to figure:
Shown in Figure 1, lifting device uses overhead traveling crane in the prior art, and overhead traveling crane belongs to large scale equipment, and operating room is in
Place far from rotor mounting location.Turn to need field personnel and the close cooperation of overhead traveling crane driver using overhead traveling crane lifting.
Link up it is very inconvenient, be very easy to generate because delay caused by operating error.
And Fig. 2-Fig. 6 show large-size machine described in the utility model take out, wear rotor specific purpose tool structure and it
Operating process show.It include moving door frame 4, horizontal gird 5, chain block 6, the first dummy shaft 31,32 and of the second dummy shaft in figure
Rotor 1, motor stator 2.
First dummy shaft 31 and 1 left end of rotor are affixed, and length is equivalent to 1 length of rotor, and left end is provided with lifting
Point；
Second dummy shaft 32 and 1 right end of rotor are affixed, and the right-hand end of the second dummy shaft 32 is provided with lifting point；It further include movement
Door frame 4 sets horizontal shore 5 at the top of moving door frame 4, sets that there are three chain blocks 6 on horizontal shore 5；Hand positioned at two sides
It draws cucurbit 6 to connect respectively with the first dummy shaft 31, the second dummy shaft 32, is located in the middle hand-held cucurbit 6 equipped with hanging belt 7；Hanging belt 7
When 1 extraction section of rotor is far beyond its position of centre of gravity, it is mounted on rotor 1.
Take out using above-mentioned tool the operation of rotor are as follows:
1) first by moving door frame 4 across standing on above motor；
2) the first dummy shaft 31 is sleeved on 1 left end of rotor, the second dummy shaft 32 is sleeved on 1 right end of rotor；
3) 6 position of chain block of two sides is adjusted respectively, and lifting point is installed and is fixed, the lifting direction of chain block 6
It is vertical with rotor 1；
4) two sides chain block 6 is played, rotor 1 and 2 gap of stator are adjusted；
5) after gap is uniform, moving door frame 4 is pushed, rotor 1 is extracted out outward, finds gap mistake during such as pumping rotor
Hour, 6 Secondary Control gap of chain block can also be used；
6) when 1 extraction section of rotor is far beyond its position of centre of gravity, rotor is caught with the hanging belt 7 of intermediate chain block
1, the first dummy shaft 31 is removed later, with intermediate chain block and right side chain block hoisting rotor 1, continues to push away moving door frame 4, it is complete
Full extraction rotor.
Operating for rotor, which is worn, using this tool is using sequentially, here for three chain blocks with pumping rotor operation difference
It repeats no more.
As can be seen that this tool is taken out, wear that rotor takes always is two o'clock lifting, to the pumping of rotor, wear construction when it is inevitable
It is more more stable than original some lifting；Using this specific purpose tool, during taking out, wearing rotor, rotor can be adjusted at any time and is determined
The gap of sub- chamber can effectively reduce colliding between stator and rotor, the precision and stability for improving pumping, wearing rotor, drop
The low risk that motor is damaged during taking out, wearing rotor.
