Description

Adjustable connecting device for mine monorail crane track Technical Field The utility model relates to the technical field of monorail cranes, in particular to an adjustable connecting device for a mine monorail crane track. Background The rail hanging rail transportation system is one of the most important auxiliary transportation equipment systems of the coal mine, and the installation quality of the single rail hanging rail directly determines the running speed and the running safety of a single rail crane of the single rail hanging rail transportation system. The monorail crane rail is characterized in that a plurality of I-steel monorails are connected by a monorail crane rail hanging device and hung on a roadway or other fixed structures. Monorail crane tracks are usually formed by splicing multiple sections of tracks, however, at present, the traditional track connection mode is generally fixed by bolts.
