Description

Technical Field

[0001] The utility model relates to the technical field of blasting engineering, in particular to a detonator foot line fixing warning device. Background Art

[0002] When conducting open-air blasting operations, several blastholes will be dug on the blasting surface, and detonators will be placed in the blastholes to prepare for blasting. After the detonators are loaded with explosives, the detonator leg wires and busbar clamps will be at the hole mouth, waiting for inspection and confirmation, and then all detonators will be connected through a busbar. During the charging and inspection period, especially when the scale of one-time blasting is relatively large, there will be many detonator leg wires and busbar clamps waiting at the hole mouth. In order to prevent the detonator leg wires from slipping into the hole, workers usually reserve more leg wires for prevention, or simply use stones to wrap or press them. Although it has a certain effect, it still exists to prevent the detonator leg line from accidentally falling or sliding into the hole due to gravity or external force. Not only does it take a lot of time to salvage it, but more importantly, the hole is narrow and slender, which makes it extremely difficult to salvage it, and it is often impossible to salvage it, which creates safety hazards, affects project production and increases management burden. When the blasting range is large, more blastholes will be dug, and workers may place multiple detonators in the same blasthole if they are not careful, affecting the quality of the blasting. At the same time, since the number of detonators is fixed, when they are placed incorrectly, they need to be re-checked, which will take a lot of time. Utility Model Content
