AI Technical Summary
When large cranes are running on rails, foreign objects on the rails can cause severe wear on the wheel flanges, which may even lead to derailment accidents. Existing rail guide wheels cannot effectively remove foreign objects, affecting the safe operation of the cranes.
A special cleaning fixture for crane trolley traveling mechanism has been designed, which includes a cleaning box, a cleaning mechanism and a flexible moving mechanism. The cleaning motor drives the cleaning brush to clean foreign objects on the track, and the cooperation of the moving wheels and the lifting frame ensures that the cleaning equipment does not conflict with the crane traveling mechanism, thus achieving automatic cleaning.
It enables automatic removal of foreign objects from the track, avoiding wear and tear and safety hazards during crane movement, and ensuring the normal operation of the crane.
