Description

Technical Field

[0001] The utility model belongs to the technical field of drill bit hangers, in particular to a drill bit hanger which can avoid falling off. Background Art

[0002] In engineering construction operations, some large equipment and large auxiliary tools are often needed. For example, drill bits are used for drilling large holes in engineering construction. Such drill bits have a large volume and mass. In order to better transport them, most of them will use cranes and hoisting tools to hoist the drill bits. However, the commonly used drill hoists cannot fix the drill bits well, which may cause the drill bits to fall off during the hoisting process. The fall of a large-volume and high-mass drill bit poses a great safety hazard, which directly causes great personal injury. After falling, it will hit other objects, which will also cause other objects to be shattered or splashed, which also poses a great safety hazard.

[0003] Secondly, the falling of the drill bit may cause certain bumps and damages to the drill bit itself, causing its key parts to break, making it unusable. Moreover, after falling, it needs to be hoisted again, which increases the hoisting time and the labor intensity of the operator.
