Description

Technical Field

[0001] This utility model relates to a lifting device for flipping the wired stator of a large motor. Background Technology

[0002] Currently, the wired stator of a motor consists of an iron core and winding coils. The iron core is made of laminated silicon steel sheets. After the coils are embedded in the stator slots, they are wired and the ends are wrapped. After passing inspection, they are transferred to the next process for varnish impregnation and insulation treatment. Then, the wired stator is pressed into the frame to form the stator. In the above process, the wired stator needs to be rotated from horizontal to vertical or vice versa. For example, the wired stator is horizontal when wired, vertical when impregnating, horizontal when stored, and then rotated from horizontal to vertical when pressed into the frame. During operation, the wired stator is rotated horizontally and vertically in this way, which is inconvenient and prone to collisions, damaging the end coils, causing exposed copper, and seriously affecting product quality. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a lifting tool for flipping the wired stator of a large motor. By designing a special clamp and flipping mechanism, it ensures that the wired stator is not damaged during the flipping process, thereby improving flipping efficiency and product quality. The tool has a simple structure and is easy to operate.

Detailed Implementation

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0014] like Figures 1 to 4 The image shows a lifting device used for flipping the wired stator of a large electric motor, comprising: Hanger 2, tilting frame 7 and limiting structure; the tilting frame 7 is rotatably mounted on the hanger 2, and the limiting structure is mounted on the hanger 2 or the tilting frame 7 to enable the tilting frame 7 to be horizontally and vertically positioned after tilting. Rotating shaft 14; the rotating shaft 14 is rotatably mounted on the tilting frame 7, and the rotating shaft 14 is provided with external threads; and The system includes a fixed base 8, a base 13, and two or more sets of support components. The fixed base 8 has an internal thread, is mounted on a rotating shaft 14, and the internal thread of the fixed base 8 meshes with the external thread of the rotating shaft 14, allowing the rotating shaft 14 to move up and down relative to the fixed base 8. The base 13 is mounted on one end of the rotating shaft 14 and can rotate relative to the rotating shaft 14 and move up and down with the rotating shaft 14. The support components include a first connecting plate 9, a second connecting plate 12, a support frame 11, and a support plate 10. One end of the first connecting plate 9 is rotatably connected to the fixed base 8, and the other end of the first connecting plate 9 is rotatably connected to the support frame 11. One end of the second connecting plate 12 is rotatably connected to the support frame 11, and the other end of the second connecting plate 12 is rotatably connected to the base 13. The support plate 10 is mounted on the support frame 11.

[0015] In use, the support assembly extends into the motor stator. After extension, the user rotates the shaft 14. The thread of the shaft 14 rotates within the thread of the fixed seat 8, causing the base 13 to move. This causes the relative distance between the fixed seat 8 and the base 13 to change with the movement, thereby moving the second connecting plate 12, the first connecting plate 9, and the support frame 11. The support frame 11 expands outward, and the support plate 10 supports the inner wall of the motor stator, thus supporting the motor stator. After being supported, the user swings the flipping frame 7 to control whether the motor stator is placed vertically or horizontally.

[0016] In this embodiment, the limiting structure is a positioning protrusion 15 and a positioning pull rod 17, which are installed on the flip frame 7. When the flip frame 7 is horizontally positioned, the positioning protrusion 15 abuts against the hanger 2 to position the flip frame 7 horizontally. When the flip frame 7 is vertically positioned, the user moves the positioning pull rod 17, and the positioning pull rod 17 abuts against one side of the hanger 2 to position the flip frame 7 vertically.

[0017] In this embodiment, a rotating handle 5 is also included; the rotating handle 5 is installed at the other end of the rotating shaft 14. This makes operation convenient.

[0018] In this embodiment, an assistive structure is also included; the assistive structure is an assistive rod 4, the end of which is forked, and a hook 3 is installed at the end of each fork. The hook 3 can hook the rotating handle 5, thereby lengthening the lever arm. In use, the lengthened lever arm makes it easier to rotate and requires less effort.

[0019] In this embodiment, a bushing 16 is provided on the flipping frame 7, and the rotating shaft 14 is rotatably mounted on the flipping frame 7 through the bushing 16.

[0020] In this embodiment, a flipping handle 6 is also provided on the flipping frame 7. In this embodiment, a lifting ring 1 is provided on the upper part of the hanger 2.
