Description

Technical Field

[0001] This utility model relates to the field of motor repair technology, specifically a high-voltage motor winding disconnection tool. Background Technology

[0002] When a motor winding is burned out or short-circuited between turns and requires major repair, the motor components must be recorded and disassembled. Removing the motor winding is an essential part of the major repair. It is crucial to ensure that the motor core and slots are intact and undamaged, making the winding removal process particularly important.

[0003] Because the high-voltage motor windings are very firmly fixed in the iron core slots, it is very difficult to remove the motor windings by hand. Usually, a self-made extended wedge is used to knock and pry the windings at the bottom of the iron core slots to make the windings expand out of the iron core slots. The labor cost of the maintenance process is relatively large. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a high-voltage motor winding disconnection tool, which solves the problem of high workload for maintenance personnel.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A high-voltage motor winding disconnection tool is characterized by comprising a rotating shaft, which is horizontally mounted on a bracket, the bracket being mounted on a fixed platform, a limiting groove at both ends of the rotating shaft, and a roller assembly at each end of the rotating shaft, the limiting groove and the roller assembly being fitted together, an iron chain on the rotating shaft, and a hook at the end of the iron chain for hooking the motor winding.

[0006] One end of the rotating shaft is connected to the output shaft of the reducer via a universal joint, and the reducer is connected to the main shaft of the motor.

[0007] The beneficial effects of this utility model are: when the winding is removed, the limiting groove and the roller group on the bracket are installed together to prevent the shaft from running off-center. The mechanical rotation changes the linear force of the motor winding into a vertical winding force, and the motor winding is lifted and removed one by one, reducing labor intensity.

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0011] like Figure 1 As shown, a high-voltage motor winding disconnection tool is characterized by comprising a rotating shaft 8, which is horizontally mounted on a bracket 7, the bracket 7 being mounted on a fixed platform 4, a limiting groove 9 at both ends of the rotating shaft 8, and a roller assembly at each end of the rotating shaft 8, the limiting groove 9 and the roller assembly being fitted together, a chain 5 on the rotating shaft 8, and a hook 6 at the end of the chain 5 for hooking the motor winding.

[0012] like Figure 1 As shown, one end of the rotating shaft 8 is connected to the output shaft of the reducer 2 via the universal joint 3, and the reducer 2 is connected to the main shaft of the motor 1.

[0013] When using this utility model, a YE4160L-411KW motor 1 is equipped with a reducer 2 with an output ratio of min71 rpm. A 5M*100mm rotating shaft 8 is connected through a universal joint 3. The hook 6 hooks the end of the coil. The motor 1 is started to drive the rotating shaft 8 to rotate. The mechanical rotation changes the linear force of the motor winding into a vertical winding force, and the motor winding is disassembled one by one.

[0014] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
