The power of the driving device is transmitted to the cycloidal pinwheel reducer through the belt through the adjusting motor, and then from the reducer to the driving spindle through the chain sprocket. Finally, the driving wheel directly drives the conveyor chain to move in the closed rail cavity to transport suspended objects forward. When a fault occurs during operation and the traction force is overloaded, the adjustable safety clutch set on the drive device immediately automatically disengages, and at the same time, its movable half-clutch presses the electrical travel switch, causing the motor to stop and the entire line to stop running. After the fault is eliminated, re-engage the clutch end face. At this time, the engine can be started and run normally without any adjustment.
