AI Technical Summary
In the existing technology, the design specifications of traction motors for different types of trains in the railway transportation system vary greatly, which means that each type of motor requires a maintenance platform with specific size parameters, resulting in low utilization of maintenance workstations and long maintenance time.
A maintenance platform for train traction motors was designed, featuring an arc-shaped clamping plate and an adjustable support structure. This allows it to adapt to motors of different sizes and center of gravity distributions. Automatic clamping and stabilization are achieved through cylinder drive, while rubber protective blocks and casters ensure the stability and compatibility of the motors.
It enables adaptation to a variety of motors without manual adjustment, improving maintenance efficiency, preventing motor tipping and damage, and enhancing the versatility and safety of the maintenance platform.
