Description

Technical Field

[0001] The utility model relates to the field of open-pit blasting hole protection, and specifically to a safety plug for mine blasting. Background Technique

[0002] Mine blasting technology is mainly used to break rocks so as to more easily extract ores. This technology plays a crucial role in mine exploitation, which can improve the exploitation efficiency and promote resource utilization. The economic benefit of blasting is related to the hole diameter of the blast hole and the loss of equipment. The drilling diameter is generally between 40 mm and 90 mm, and can reach 300 mm when large. During the blasting process, the larger the blast hole diameter, the smaller the equipment loss, and better benefits can be generated.

[0003] In safety production, if the hole diameter is too large and the hole opening protection is insufficient, electronic devices such as mobile phones and walkie-talkies may accidentally slip into the blast hole; equipment such as detonators may be damaged due to being trampled by subsequent construction workers if placed beside the hole opening as Figure 2 shown. Currently, to prevent the occurrence of the above situations, some packaging bags or stones are generally used to temporarily seal the blast hole for too large hole diameters, and only the awareness can be improved for preventing the trampling of equipment.

[0004] The existing safety plug for mine blasting is not easy to effectively block the hole opening, and its compressive capacity is very poor. More dangerously, accidents are likely to occur when equipment such as detonators is trampled. The existing safety plug for mine blasting is not easy to achieve convenient disassembly, assembly and adjustment of the device, which may lead to a reduction in the safety and stability of the device.

[0005] Therefore, a safety plug for mine blasting is proposed for the above problems. Content of the Utility Model

The bottom end of a connecting piece is fixedly connected to the top of the sealing plug. The top end of the connecting piece is fixedly connected to a conical placement net. The top of the conical placement net is fixedly connected to an installation ring. A rotating shaft is rotatably connected above the installation ring. A cover plate is snap-fitted inside the rotating shaft. A handle is fixedly connected to the top of the cover plate. An installation frame is sleeved on the surface of the connecting piece, and a threaded column is in threaded cooperation with the surface of the installation frame.

[0008] Preferably, a pressing rod is fixedly connected to one side of the rotating shaft, and the bottom surface of the pressing rod abuts against the top surface of the cover plate.

[0009] Preferably, a number of collars are fixedly connected to the surface of the connecting member at equal distances, and the size of the upper bottom surface of the plug is larger than the size of the lower bottom surface of the plug.

[0010] Preferably, clamping grooves are formed on both sides of the cover plate, and the shape of the clamping groove fits the shape of the inner side of the rotating shaft.
