Description

Technical Field

[0001] The utility model relates to the technical field of large-scale equipment maintenance, in particular to a tooling structure suitable for turning over a motor rotor. Background Art

[0002] A vertical motor is a motor whose output shaft is perpendicular to the chassis or the speed change mechanism. Large motor equipment requires regular maintenance and inspection to ensure its normal operation. For vertical motors, it is often necessary to first remove the rotor when disassembling it, and then perform corresponding work arrangements on the stator and rotor, such as maintenance, inspection, repair, and testing. After completion, the rotor is inserted back to continue the next work cycle.

[0003] Therefore, there are currently two ways to extract the rotor of a vertical motor:

[0004] One is to lift the rotor by a crane and place it on the bracket in a vertical state. However, due to the long rotor, it is impossible to conduct a comprehensive inspection when it is placed in a vertical state. The other is to install a flip anchor on the foundation, and use the crane and the anchor to flip the rotor and place it on the bracket in a horizontal state. However, this method has certain requirements for the foundation, and the anchor cannot be removed.

[0005] In view of the above deficiencies in the prior art, the utility model designs a tooling structure suitable for flipping a motor rotor, which can flip the motor rotor from a vertical state to a horizontal state with the cooperation of only one lifting tool, thereby performing inspection and maintenance on the motor rotor. Summary of the invention

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a tooling structure suitable for turning over a motor rotor, which can turn over the motor rotor from a vertical state to a horizontal state with the cooperation of only one lifting tool, thereby enabling inspection and maintenance work to be performed on the motor rotor.

[0007] In order to achieve the above purpose, the utility model provides a tooling structure suitable for flipping a motor rotor, one end of the rotor is connected to a hoist a at the lower end of a triangular tooling through a lifting tooling, the other end of the rotor is connected to a hoist b at the lower end of the triangular tooling through a flipping tooling, and the top of the triangular tooling is connected to a crane.

[0008] The positions of gourd a and gourd b can be interchanged.

[0009] Hoist a and hoist b are provided with hooks for contraction or extension.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model connects the two ends of the rotor to the two ends of the bottom of the triangular tooling in sequence, thereby realizing the function of lifting the rotor from a vertical state to a horizontal state, during which the angle of the rotor can be flexibly controlled by adjusting the hook lengths of the hoist a and the hoist b.

[0012] By using the triangular fixture, even if the center of gravity of the rotor changes in real time, the self-balancing property of the triangular fixture can keep the center of gravity of the rotor from shifting too much as much as possible, reducing the phenomenon of the rotor swinging back and forth. This makes it possible to quickly lift the rotor, and after the rotor is flipped horizontally, it can be placed on the bracket. In this process, the rotor is stable, easy to control, with a high safety factor and low operating difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is now further described with reference to the accompanying drawings.

[0018] See also Figures 1-2 The utility model provides a tooling structure suitable for flipping a motor rotor. One end of a rotor 7 is connected to a hoist a5 at the lower end of a triangular tooling 1 through a lifting tooling 2, and the other end of the rotor 7 is connected to a hoist b6 at the lower end of a triangular tooling 1 through a flipping tooling 3. The top end of the triangular tooling 1 is connected to a crane 4.

[0019] The positions of gourd a5 and gourd b6 can be interchanged.

[0020] Hoist a5 and hoist b6 are provided with hooks for contraction or extension.

[0021] Working principle:

[0022] The utility model does not need much debugging when in use. The lifting tool 2 is installed on one side end face of the rotor 7, one corner of the triangular tool 1 is installed on the hook of the crane 4, one corner of the triangular tool 1 is installed with a hoist a5, and the hook of the hoist a5 is connected to the lifting tool 2.

[0023] The rotor 7 is hoisted in a vertical state as a whole by the crane 4. After the rotor 7 is hoisted out of the motor, the flip tool 3 is installed at the other end of the rotor 7, and the hoist b6 is installed at the remaining corner of the triangular tool 1, and the hook of the hoist b6 is connected to the flip tool 3.

[0024] The hoist a5 hook is slowly extended while the hoist b6 hook is retracted to slowly flip the rotor 7 from a vertical state to a horizontal state. When the rotor 7 is in a horizontal state, the rotor can be moved to a bracket and placed.
