Abstract
The utility model discloses a trolley used for the mounting of a large magnetic pole. The magnetic pole comprises a pole body and a pole shoe with a circular arc-shaped upper end surface; the trolley comprises a trolley body and four wheels assembled on the bottom of the trolley body; the trolley body is a flat plate; a circular arc-shaped bed timber, the upper end surface of which is matched with the circular arc-shaped surface of the pole shoe, is arranged in the middle of the trolley body; the magnetic pole is laid on the bed timber; and four hanging hooks are respectively assembled on the four corners of the trolley body. After the technical scheme of the trolley used for the mounting of the large magnetic pole is adopted, the problem on how to lift, turn over and axially and radially position the large magnetic pole is resolved, and the magnetic pole can be mounted in place in one step.
Description
Technical field
The utility model relates to a kind of dolly that is used for large-scale magnetic pole installation high-power, slow speed of revolution frequency control roughing motor that is suitable for.
Background technology
High-power, slow speed of revolution frequency control roughing motor is the roughing motor of capacity 7200kW, and number of poles is 16P, and voltage is 3000V, and rotating speed is 40～80r/min, and rotor diameter is 3030mm, and length overall is 7407mm.Usually the fixed form of magnetic pole has following several: first magnetic pole bottom is done "T"-shaped or two "T"-shaped, and magnetic pole is packed into and fixed magnetic pole with beating the taper key method behind the corresponding "T"-shaped groove of yoke; It two is that " dove tail " shape is made in the magnetic pole bottom, and magnetic pole is packed into and fixed magnetic pole with beating the taper key method behind yoke correspondence " dove tail " the shape groove.These two kinds of methods all will be slotted in yoke surfaces, are used in hollow shaft wall thickness 160mm and go up obvious insufficient strength.The third method is exactly the most frequently used magnetic pole bottom loading screw method.But loading screw structure magnetic pole can only be used for short iron core and less magnetic pole usually, and this roughing of picture motor pole long 2000mm unshakable in one's determination, the heavy 1880kg of magnetic pole, also need solve the control of magnetic pole axial dimension in the installation, standing screw such as entad adjusts at problem, therefore need to improve the structure of magnetic pole and the installation method of magnetic pole, must supporting employing be installed by frock accordingly.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of dolly that large-scale magnetic pole is installed that is used for of magnetic pole accurate positioning is provided, and it has solved large-scale magnetic pole handling, has stood up; Axially, the difficult problem of radial location.
A kind of technical scheme that realizes above-mentioned purpose is: a kind ofly be used for the dolly that large-scale magnetic pole is installed, described magnetic pole comprises that pole body and upper surface are the pole shoe of arc surface, and described dolly comprises car body and be installed in four wheels under the car body, wherein,
Described car body is a flat board, and the midway location on this car body is provided with the arc surface sleeper of the arc surface coupling of a upper surface and pole shoe;
Described magnetic pole is placed upside down on this sleeper;
On four angles of described car body a suspension hook is installed respectively.
Above-mentioned be used for the dolly that large-scale magnetic pole is installed, wherein, described four wheels are installed in respectively near four bights of car body and can be along 360 ° of rotations of perpendicular line.
After having adopted the technical scheme that is used for the dolly that large-scale magnetic pole installs of the present utility model, solved large-scale magnetic pole handling, stood up; Axially, a radial location difficult problem, magnetic pole is installed one-time-reach-place.
Description of drawings
Fig. 1 is the structural representation that is used for the dolly of large-scale magnetic pole installation of the present utility model;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 and Fig. 2, magnetic pole 1 comprises that pole body 11 and upper surface are the pole shoe 12 of arc surface.
The dolly that is used for large-scale magnetic pole installation of the present utility model comprises car body 2, sleeper 3, suspension hook 4 and four wheels 5, wherein,
The upper surface of sleeper 3 be one with the arc surface of the arc surface of pole shoe 12 coupling;
Four wheels 5 are installed near four bights under the car body 2 and can be along 360 ° of rotations of perpendicular line;
The bottom surface of magnetic pole 1 iron core is equipped with seven dress utmost point screw rods 13
It is dress utmost point screw rod 13 and the dress utmost point nut that axially is distributed on the pole core bottom surface by seven that magnetic pole on the AC/AC (alternating current) variable-frequency steel-rolling motor rotor is connected with rotating shaft.Magnetic pole 1 is with before rotating shaft is connected; elder generation replaces with pilot bar 14 respectively at the dress utmost point screw rod 13 at two of close pole core end; pilot bar 14 is a frock; length is longer than dress utmost point screw rod 13; diameter plays protection product dress utmost point screw rod 13 and the positioning action of magnetic pole 1 in rotating shaft than the little 0.5～0.7mm of magnetic pole screw on the quill shaft (not shown).The dolly that is used for large-scale magnetic pole installation of the present utility model is pulled to adjustment position in back under the rotating shaft when the dress utmost point, the mounting hole that pilot bar 14 is aimed in the rotating shaft, hook suspension hook 4 liftings with hoist cable 6 then, make dress utmost point screw rod 13 and pilot bar 14 enter cooresponding mounting hole in the rotating shaft, dress utmost point nut on the dress utmost point screw rod 13 of elder generation five centres of pretension, remove pilot bar 14 again, the product that changes the outfit dress utmost point screw rod 13, fastening with dress utmost point nut at last.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
