A large-scale annular motor rotor electrode block symmetric assembling method comprises a first step of scaffold platform establishment for establishing a scaffold platform in a to-be-installed rotor and setting an installing position based on a site condition; a second steps of first electrode block installation for craning a first electrode block to the installing position for installation, and carrying out centralized positioning according to a flange center; a third step of rotating the rotor for 180 degrees to enable the symmetrical position of the first electrode block to enter the installing position and carrying out rapid installation of a second electrode block; a fourth step of rotating the rotor for 90 degrees and carrying out installation of a third electrode block according to the first and second steps; a fifth step of rotating the rotor for 180 degrees and carrying out installation of a fourth electrode block; a sixth step of rotating the rotor in sequence based on the steps 2 to 6, and sequentially finishing installation of all the electrode blocks according to a symmetrical principle; a seventh step of carrying out rounding adjustment for all the electrode blocks. According to the large-scale annular motor rotor electrode block symmetric assembling method, occurrence of accumulated errors can be reduced, and the centrifugal force in a rotor rotation process is reduced to the minimum value.
Description
Technical field
The present invention relates to annular generator, particularly relate to the rotor of annular generator.
Background technology
Large-sized annular motor is a kind of comparatively novel motor, and its rotor is made up of electric electrode block and machinery tubular equipment, and electrode block is dispersed into scene, and the rotor of a motor is generally divided into tens cube electrode blocks, and every piece has 4～6 groups of windings.Usual rotor windings is installed and is adopted installation method clockwise or counterclockwise, and this method exists the problem of cumulative error, generally requires to refund and readjusts.Owing to rotor electric machine block Heavy Weight can produce bigger eccentric centrifugal power when using conventional mounting arrangements to rotate, slewing and workmen are damaged.
Summary of the invention
It is contemplated that overcome the defect of prior art, it is provided that a kind of large-sized annular rotor electrode block symmetry assemble method.The present invention can reduce the appearance of cumulative errors, and in rotor rotation process, centrifugal force is minimized value.
In order to solve above-mentioned technical problem, a kind of large-sized annular rotor electrode block symmetry assemble method, described rotor is circular, and described assemble method includes:
Step one, the landing stage of scaffold is built, and builds the landing stage of scaffold in rotor to be installed, sets installation position according to field condition；
Step 2, the installation of the first electrode block, the first electrode block handling is installed to installation position, and according to flange hole centralized positioning；
Step 3, revolves turnback by rotor so that the symmetric position of the first electrode block enters installation position, and carries out the installation that the second rotor is fast；
Step 4, by rotor 90-degree rotation, such as step one and two, carries out the installation of the 3rd electrode block；
Step 5, revolves turnback by rotor, carries out the installation of the 4th electrode block；
Step 6, according to step 2 to five successively rotor, according to symmetrical principle, is sequentially completed the installation of all electrode blocks；
All electrode blocks are advised circle adjustment by step 7.
Described a kind of large-sized annular rotor electrode block symmetry assemble method, including, before described step 2, adopting rubber slab to protect on all electrode block surfaces.
Described a kind of large-sized annular rotor electrode block symmetry assemble method, described step 2 to step 6, each electrode block install time four bolts hole in two be used for positioning two for fixing.
Described a kind of large-sized annular rotor electrode block symmetry assemble method, when described step 2 installs first piece, first two bolts in the middle of rotor electrode block are penetrated and fasten 30% fastening force, the deviation of the bolt hole according to both sides and flange hole, use hydraulic jack is adjusted, it is ensured that bolt hole is concentric with flange hole.
The present invention adopts the installation method that equal portions are symmetrical, and the effective appearance reducing cumulative errors, in rotor rotation process, centrifugal force is minimized value.The present invention has the advantages that time saving and energy saving reliability is high, is effectively improved the safety in rotor rotation process.
Detailed description of the invention
A kind of large-sized annular rotor electrode block symmetry assemble method, described rotor is circular, and described assemble method includes:
One cube electrode block is lifted into installation site, and electrode block surface adopts 5mm rubber slab to protect, and places required instrument, including the specific purpose tool such as hydraulic jack, hydraulic spanner on the landing stage of scaffold built.Electrode block install time 4 bolts hole in 2 be used for positioning 2 for fixing.According to flange hole centralized positioning when installing first piece, first penetrating and fasten 30% fastening force by two bolts in the middle of rotor electrode block, the deviation according to the bolt hole of both sides Yu flange hole, use hydraulic jack is adjusted, it is ensured that bolt hole is concentric with flange hole.Ball mill barrel is revolved turnback after installing by the first cube electrode block installs the second cube electrode block, second piece of mounting means and first piece identical.Second cube electrode block installs rear ball mill barrel 90-degree rotation and installs the 3rd cube electrode block, after 3rd cube electrode block installs, ball mill barrel rotation turnback installs the 4th cube electrode block, after being installed to the tenth cube electrode block, possibly cannot install electrode block as requested, at this time will finely tune according to on-the-spot eccentric situation.Adjust etc. electrode block being advised circle after whole rotor electrode block installations.
