The present invention provides a standard inspection table for the inspection and repair of the 15 series couplers of passenger cars. At present, the inspection of the 15 series couplers of passenger cars is mainly done on the ground, and the operators place the couplers on the ground for operation, and lay rubber mats on the ground.

[0003] The current working mode has the following characteristics:

For example, the crack inspection of key parts such as the hook ear and hook tail pin hole of the coupler may not be detailed enough, leading to potential safety hazards.

[0006] 3. Limitations of maintenance equipment and tools: Traditional coupler maintenance tools may not be precise or efficient enough. For example, using a rubber hammer to tap the trigger to test the triggering effect of an automatic coupler is not only difficult to operate, but also poses a risk of harm to the personal safety of on-site maintenance workers.

The rodless cylinder of the horizontal drive mechanism drives the coupler clamping device fixing frame to approach the end of the coupler, and the coupler clamping device and the coupler are precisely aligned. This precise alignment ensures that the clamping component can correctly contact the coupler, thereby facilitating the subsequent effective transmission of the clamping force. The coupler clamping component of the coupler clamping device is driven by the clamping cylinder to clamp the coupler, which can ensure that there is sufficient friction with the contact surface of the coupler, thereby preventing the coupler from moving or sliding. When the coupler is clamped, the coupler is driven to rotate by the coupler rotating component, thereby realizing precise control of the all-round automated maintenance operation of the passenger car coupler, thereby improving the operation efficiency and safety.

The system ensures the stability of the coupler during the inspection and repair process and prevents it from sliding through pneumatic or hydraulic clamping, precise alignment, and controlled rotation. It reduces the need for manual operation and operational risks through automated control, and can improve the accuracy and consistency of inspection and repair. The present invention can be applied to the fields of bus manufacturing, repair, and maintenance, and can ensure the stability and safety of the coupler during inspection and repair, while also improving operational flexibility and efficiency.
