AI Technical Summary
In existing technologies, adjusting the height of rail clamping wheels is inconvenient and they are prone to loosening due to vibration, resulting in low efficiency in railway line maintenance.
An adjustment groove is opened at the bottom of the clamp shaft, and the clamp shaft is hard-locked by a stop plate. Combined with the L-shaped stop plate and limit pin, the stability of the clamp shaft and the ease of operation are ensured.
This improved the adjustment speed and stability of the clamp shaft, reduced the risk of loosening, and enhanced the efficiency and safety of railway line maintenance operations.
