Description

Technical Field

[0001] The utility model relates to the technical field of accessories for bridge cranes, and particularly relates to an automatic track ash blowing device for a bridge crane. Background Art

[0002] At present, the track cleaning of bridge cranes mainly relies on rail sweepers. Rail sweepers can clean large foreign objects on the crane track, such as stones, iron blocks, etc. If the dust concentration in the crane working environment is relatively high, the crane track is prone to ash accumulation, and the rail sweeper has a poor cleaning effect on the ash accumulation, resulting in idling and slipping phenomena when the crane wheel set passes through the ash accumulation layer, which is not conducive to the safe and stable operation of the crane.

[0003] In the existing track ash blowing technology, it is often necessary to install an air compressor or air pump on the crane to provide a gas source, and only a few multi-functional overhead cranes are equipped with an air compressor or air pump according to their functions. Most bridge cranes cannot rely on an air compressor or air pump to provide a track ash blowing gas source. Content of the Utility Model
