Description

Technical Field

[0001] The present disclosure relates to the technical field of generator rotor disassembly, and particularly to a cushion block for supporting a generator rotor. Background Art

[0002] During the overhaul and disassembly, and reinstallation of a generator, the most important nodes are the processes of extracting and inserting the rotor, which are jointly completed by two overhead cranes. When the center of the rotor is moved out of the stator chamber, the two overhead cranes need to release the hooks simultaneously for position exchange. At this time, the steam side of the rotor is supported by the rotor bracket, and the excitation side moved out of the stator chamber is supported by the rotor arc cushion block. Before the overhead crane releases the hook, the left - right position and height of the excitation - side rotor arc cushion block are adjusted. After the overhead crane releases the hook, the excitation side of the generator rotor is completely supported by the arc cushion block, and the rotor is kept horizontal. However, the cushion blocks in the related art are integral, and one type of cushion block can only be applicable to one type of rotor and cannot be universal. Summary of the Utility Model

[0021] The following will describe in detail the specific implementation of the present disclosure with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0022] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" generally refer to the upper, lower, top, and bottom of the corresponding component in the gravity direction under the use state, and "inner, outer" refer to the inner and outer relative to the contour of the component or structure itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another, and do not have sequence and importance. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0023] As Figure 1-2 shown, the present disclosure provides a spacer for supporting a generator rotor, including: a base 1; and a support member 2 disposed on the top of the base 1. There are multiple types of support members 2, and the base 1 can be selectively detachably connected to multiple types of support members 2.

[0024] Through the above technical solution, the base 1 is configured as a block with a flat bottom for placing on the ground. The support member 2 is disposed on the base 1. The support member 2 is detachably connected to the base 1 and there are multiple types of support members 2. According to different rotor models, the base 1 can selectively install different support members 2. In this way, the spacer can be applicable to multiple different models of rotors, with better versatility, and there is no need to replace the entire spacer, saving costs. When the rotor is disassembled, the excitation side of the rotor, that is, the side of the rotor close to the exciter, is moved out of the stator bore and placed on the spacer, and the spacer plays a role of bearing weight and leveling.

[0025] As an optional implementation manner, as Figure 1 shown, the support member 2 is configured as a plate-like structure, and the plate-like structure is horizontally disposed on the top of the base 1. The plate-like structure is convenient for processing, and the plate-like structure has a certain surface area, which can be in full contact with the rotor to increase the support.

[0026] Optionally, the plate-like structure can be set to have multiple different thicknesses to form multiple support members 2. Since the part of the rotor moved out of the stator bore needs to be level with the part located on the rotor bracket, and the outer diameters of each type of rotor are different, it is necessary to adjust the height of the spacer. The thicknesses of the multiple support members 2 in the present disclosure are different, so that the heights of the support members 2 are different. By installing support members 2 with different thicknesses to adjust the overall height of the spacer, so as to be applicable to different models of rotors.

[0027] As an optional implementation manner, as Figure 1 shown, a first positioning groove 21 is provided on the upper surface of the support member 2. The first positioning groove 21 is an arc-shaped groove for fitting with the side wall of the rotor to position the rotor and prevent the rotor from translating and swaying left and right.

[0028] Optionally, the plate-like structure can be bent into first positioning grooves 21 with various different radian values to form various support members 2. The radian values of the first positioning grooves 21 of the various support members 2 are different and are used to adapt to the side walls of various rotors.

[0029] At this time, there can be multiple implementation manners, and the specific implementation manner can be determined according to the actual situation:

[0030] In the first implementation manner, the thicknesses of the various support members 2 are the same, and the radian values of the first positioning grooves 21 are different;

[0031] In the second implementation manner, the thicknesses of the various support members 2 are different, and the radian values of the first positioning grooves 21 are the same;

[0032] In the third implementation manner, the thicknesses of the various support members 2 are different, and the radian values of the first positioning grooves 21 are also different.

[0033] Optionally, a second positioning groove 11 is provided at the top of the base 1. The bottom of the support member 2 is configured to be arc-shaped, and the radian values of the bottoms of the various support members 2 all match the second positioning groove 11. Since the base 1 is fixed, the arc shapes of the bottoms of the various support members 2 need to be consistent. Since the first positioning groove 21 is formed by bending the plate-like structure, the bottom of the plate-like structure is also arc-shaped. A second positioning groove 11 is provided at the top of the base 1, and the arc-shaped bottom of the support member 2 is placed in the second positioning groove 11 to fix the support member 2 and prevent the support member 2 from shaking. Since the radian values of the first positioning grooves 21 of the various support members 2 are different, while the arc radian value of the bottom of the support member 2 is fixed, secondary processing needs to be performed on the first positioning groove 21 or the arc shape of the bottom of the support member 2. For example, the bending angle of the support member 2 is fixed, and the first positioning groove 21 is processed by means such as cutting. Alternatively, the bending angles are different, and the arc shape of the bottom of the support member 2 is processed to match the second positioning groove 11. In other implementation manners, the top of the base 1 can also be set to be a plane, and the bottom of the support member 2 is also a plane, and the first positioning groove 21 is machined on the upper surface of the support member 2.

[0034] As an optional implementation manner, as Figure 1-2 shown, a first screw hole 12 is provided at the top of the base 1, and a second screw hole 22 corresponding to the first screw hole 12 is provided on the support member 2. The support member 2 and the base 1 are detachably connected by a bolt 3. The support member 2 is detachably connected to the base 1 by the bolt 3. The bolt 3 passes through the second screw hole 22 on the support member 2 from top to bottom and is threadedly connected to the first screw hole 12 on the base 1. Of course, in other implementation manners, detachable connection can also be achieved by other means, such as by means of a buckle.

[0035] Optionally, connection edges 23 extending in the horizontal direction are provided at both ends of the support member 2. A lapping platform 13 corresponding to the connection edge 23 is provided on the base 1. The first screw hole 12 is provided on the lapping platform 13, and the second screw hole 22 is provided on the connection edge 23. The support member 2 is lapped on the lapping platform 13 on the base 1 through the connection edge 23 and is connected by a bolt 3. The connection edge 23 is horizontally arranged, which is convenient for opening screw holes and installing the bolt 3.

[0036] Optionally, the second screw hole 22 is configured as a stepped hole. The diameter of the end of the stepped hole close to the base 1 corresponds to the diameter of the first screw hole 12, and the diameter of the end far from the base 1 is larger than the diameter of the first screw hole 12 and larger than the diameter of the screw head of the bolt 3, so that the screw head of the bolt 3 can be accommodated in the second screw hole 22, so that the bolt 3 can completely extend into the support member 2, preventing the bolt 3 from protruding from the support member 2 and interfering with the placement of the rotor.

[0037] As an alternative embodiment, the support member 2 can be made of any suitable material, and usually a material with a hardness less than that of the outer wall of the rotor is used to prevent damage to the rotor. Exemplarily, in the present disclosure, the support member 2 is made of copper or aluminum.

[0039] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable manner. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0040] In addition, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
