[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] The motorized roller bracket for rotor maintenance of this embodiment is shown in FIG. Figure 1-Figure 4The design features of the bracket are that the single piece is small in size, occupies a small area, the whole set is neat and beautiful, the positioning and placement are accurate, the support is stable and safe, the operation is convenient and the maintenance is simple. It includes a base frame 1, and a moving component 11 is arranged on both sides of the base frame 1. The moving component 11 includes a plurality of through holes 111 opened on both sides of the base frame 1. Two roller frames 2 are detachably arranged on the base frame 1. Matching through holes are opened on the bottom of both sides of the roller frame 2 to move and match the through holes 111 on both sides of the base frame 1. The moving component 11 also includes bolts 112, and the bolts 112 fix the roller frame 2 after adjustment. The moving component 11 is arranged between the base frame 1 and the roller frame 2, so that the position of the roller 41 can be moved and adjusted on the base frame 1, and then fixed for use. The moving component 11 ensures that the support center of the roller 41 coincides with the center of the rotor, and the positioning and placement are accurate.

[0029] In order to better limit the roller, in this embodiment, see Figure 2 , the tops of both sides of the two roller racks 2 are provided with matching grooves 21, and roller assemblies 4 are mounted on the matching grooves 21 on both sides. The tops of both sides of the roller racks 2 are detachably fixed with limiting plugs 3 to cooperate with the matching grooves 21 to limit the roller assemblies 4. The roller assemblies 4 include rollers 41, and both sides of the rollers 41 are mounted in the matching grooves 21. One side of the rollers 41 is axially detachably provided with connecting disks 42, and the inner ring of the connecting disks 42 is provided with internal teeth. The easy-to-disassemble design of the rollers 41 and the roller racks 2 allows the staff to clean and maintain the brackets themselves more conveniently, which can keep the brackets in good condition, extend their service life, and make it faster to replace parts and repair equipment. The rollers 41 are nylon rollers, which will not damage the rotor journals, and there is no need to install fake tile sleeves on the journals.

[0030] In order to drive the roller to make the device run, in this embodiment, see Figure 1 and Figure 3 , support plates 22 are welded on the sides of the two roller frames 2, and power components 5 are arranged on the support plates 22 to drive the roller components 4. The power components 5 include a reducer 51, which is detachably fixed on the side support plates 22 of the roller frames 2, and a driving motor 53 is connected to one side of the reducer 51. The output shaft of the reducer 51 passes through the roller frames 2 and a driving tooth column 52 is fixedly arranged at its end, and the driving tooth column 52 meshes with the internal teeth on the connecting plate 42.

[0031] A placement slot 23 is provided on one side of the roller frame 2 to place maintenance tools, which is convenient for the staff to use and improves maintenance efficiency.

[0032] The method of using the electric roller bracket for rotor maintenance of the utility model is as follows: after using the moving component 11 on the bracket to move the roller 41 on the roller frame 2 to the required position, use the bolt 112 to fix the adjusted roller frame 2, and adjust it as needed, place the rotor on the roller 41, and ensure that the placement position is stable, and use the corresponding tools and equipment placed in the placement groove 23 of the roller frame 2 to inspect, repair and repair the rotor. When it is necessary to repair the high part of the rotor, the roller 41 can be driven to rotate by controlling the drive motor 53. The rotation of the roller 41 can drive the rotor to rotate at a low speed. When the rotor rotates to the appropriate position, the drive motor 53 can be turned off, which greatly facilitates the maintenance of the motor rotor. After the inspection, maintenance and repair are completed, the rotor and the bracket are moved to the original position, and ensure that they are placed firmly, and then the next rotor is inspected, repaired and repaired, and the above steps are repeated until all the repair work is completed.
