Description

Technical Field

[0001] The utility model relates to the technical field of bridge cranes, in particular to an anti-off-track alarm device for a bridge crane. Background Technique

[0002] A bridge crane is a hoisting device that spans over workshops, warehouses, and yards for material hoisting. Since its two ends are seated on tall concrete columns or metal brackets, it resembles a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on both sides of the elevated racks, and can make full use of the space under the bridge to hoist materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest application range and the largest number.

[0003] When the current bridge crane is in use, since the wire is transmitted through the transmission wheel structure, the wire transmission will form a situation of off-track. After the off-track, it will cause damage to the wire and affect the subsequent transmission and hoisting use. When using a single guide plate structure for guiding to prevent off-track, the effect of guiding and preventing off-track is not good, and the effect of off-track alarm cannot be formed either.

The adjustable structure can meet the anti-slip installation and use of multiple cranes. At the same time, it is combined with the real-time pressure monitoring structure to make the anti-slip alarm more efficient and accurate. BRIEF DESCRIPTION OF THE DRAWINGS
