1results about How to "Not fall off" patented technology

This invention discloses a large-hole blasting charging device, belonging to the technical field of charging devices. It includes a nylon rope, which hooks a bomb via a hooking mechanism. The hooking mechanism includes a first arc-shaped block and a second arc-shaped block; a connecting mechanism; and a replacement mechanism. By setting up the hooking mechanism, the second arc-shaped block hooks the explosive. During charging, after the explosive cartridge is placed at the bottom of the hole, the nylon rope is quickly pulled up. Due to inertia, the force on the spring is much greater than the weight of the explosive, causing the spring to deform. Rotation occurs between the first and second arc-shaped blocks, and the second arc-shaped block separates from the explosive, thus unhooking the explosive. The spring force is selected to be greater than the weight of a single emulsion explosive. During the charging process, the explosive is prevented from falling off, avoiding affecting the blasting effect. This method avoids the problem of the rope becoming entangled after detaching from the explosive, improving operational safety and construction efficiency. This method is applicable to all large-hole blasting charging operations, both on the surface and underground.
