Wind power generation has been rapidly developed in recent years as a clean energy source, a generator is an indispensable component of a wind generating set, a winding and a magnetic flux core of the generator generate heat in operation, and the generated heat rises with the increase of power generation, so the generator needs to be provided with a heat dissipation device. At present, a cooling fan is adopted to drive air to circulate so as to realize heat exchange between the inside and the outside of the generator. Because the running environment of the wind driven generator is poor, the motor driving the cooling fan of the generator can be damaged when running for a long time, and the wind driven generator can not run to generate electricity after the motor of the cooling fan of the generator is damaged, so the wind driven generator must be replaced in time.
The outer cooling fan motor is located between generator upper surface and the cabin cover, and the space only is about half meter, and the maintainer must lie prone on the generator upper surface, just can dismantle the cooling fan motor of damage, and the effort is difficult. The shaft of the external cooling fan motor is tightly matched with the fan connecting sleeve, rust and a small amount of deformation can occur at the joint after long-time operation, and the binding force is very high, so that the external cooling fan motor is very difficult to disassemble and assemble. The patent with the publication number of CN217452845U discloses a yaw motor disassembly tool, an arc-shaped positioning clamping seat of the yaw motor disassembly tool needs to be clamped at a gap where a motor is connected with a speed reducer, the flatness requirement on the clamping seat is very high, the phenomenon that part of the clamping seat cannot be clamped in place due to slight deformation, the device cannot be used, the arc-shaped positioning clamping seat is a bearing part during disassembly, and an opening of an inner inclined plane is thinner and is easy to deform and lose efficacy. Meanwhile, the yaw motor is pulled and detached by the two-jaw pulling machine, and a conventional motor like an external cooling fan does not have a reliable position structure for the two-jaw pulling machine to fixedly pull, and the yaw motor can only be detached by the yaw motor. The patent with the publication number of CN218110661U discloses a motor disassembly drawing tool, the device utilizes the inertia of an impact hammer to disassemble a drawing motor, the impact force of the impact hammer is limited, the disassembly efficiency of an external cooling fan motor with larger weight is extremely low, and particularly, some external cooling fan motors with larger binding force cannot be disassembled at all, and meanwhile, the device can only disassemble the motor and cannot be used for motor installation. Therefore, the inventor provides a disassembly and assembly tool for an external cooling fan motor of a fan generator.
