Description

Technical Field

[0001] The utility model relates to the technical field of underground drill rod protection equipment, in particular to an underground drill rod anti-electric shock device. Background Art

[0002] In mining production, whether underground scrap loaders can load and unload ore safely and normally has become a restrictive factor for the operation area to complete production tasks. At present, scrap loaders need to set and fix old anchor rods on the walls of both sides of the tunnel opening during the ore unloading process. The surrounding rock of the Huashugou underground iron ore is relatively hard, and the veins are not supported after excavation, resulting in a large number of protrusions. If old anchor rods are not set during ore extraction, the cables will directly rub against the protrusions, which will shorten the cable service life; secondly, the cable is easily discharged when it is damaged, causing the cable to be energized and cause electric shock.

[0003] There is no device that can solve the above-mentioned technical problems at present. Utility Model Content
