Problems solved by technology
Due to the lack of pan positioning and iron core control in the hard pull, there are great safety hazards, and the motor does not have special fixing devices and stator core protection devices. During the process of extracting the coil, the stator core is subjected to irregular tension and the iron core will be deformed.
Therefore, the current motor repair rate is low, and it requires a lot of manpower and time, and the safety is poor. More importantly, the damage of the iron core is difficult to recover, and the damage of the iron core has a great impact on the operating parameters of the motor. Even if it is repaired A good motor cannot meet the original technical requirements, which greatly reduces the service life

The invention relates to a motor coil hydraulic drawing machine, which is mainly composed of a moving trolley, a hoist, a hydraulic system, a trolley track, and a bracket. A bracket is arranged beside the moving trolley, and a hoist is arranged on the bracket. The hoist One end is connected to a hydraulic motor, which is connected to the hydraulic cylinder at the lower end of the hoist, and the hydraulic cylinder is connected to the oil station next to the support. The motor is hoisted to the mobile trolley and the coil on the motor is pulled out by the hoist. Due to the high efficiency and practicality of the invention, considerable economic benefits can be obtained in one year. And it can be mass-produced and promoted to factories all over the country, which has a broad market space.
Description
technical field [0001] The invention belongs to the technical field of non-destructive drawing tools for stator coil iron cores of electric motors, and relates to a hydraulic drawing machine for electric motor coils. Background technique [0002] Every year in Shaoguan Iron and Steel Plant, a large number of motors of various types and sizes need to be repaired and reused. Among them, replacing the winding coils of the stator and rotor is an important part of the motor repair. Before replacing the stator or rotor winding coils, the old coils must be removed. At present, most of the equipment for removing the coils of the motor adopts the direct hooking of the coils and pulling them out one by one. Pull or other electric hoisting machinery to pull the coil at the other end to pull out the coil. Due to the lack of pan positioning and iron core control in the hard pull, there are great safety hazards, and the motor does not have special fixing devices and stator core protecti...
