Detailed Description

The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not to be construed as limiting the present invention.

As shown in fig. 1, the utility model provides a quick grounding device for a cable of a mobile electrical device in a metal mine underground, which selects angle steel 2 of 40mm × 40mm, cuts the angle steel into a length of 100mm, fixedly welds an M10 bolt 1 on the outer side of one side of the cut angle steel, installs an open wire nose on a grounding wire of a shell of the mobile electrical device, connects and fixes the wire nose on an M10 bolt, and is fixedly screwed by a nut; an M12 nut is fixedly welded on the inner side of the welded M10 bolt angle steel, and the M12 bolt 3 is screwed through the M12 nut. The device is placed on an underground grounding ring net, the inner side of the angle steel on one side of the unwelded bolt and the nut is tightly attached to the grounding flat iron 4, the M12 bolt is screwed through the fixing nut, and the inner side of the angle steel is ensured to be in good contact with the grounding flat iron without loosening. When the equipment is moved, the M12 bolt is loosened, the device is moved to the next proper position, and the M12 bolt is screwed and fixed, so that the process is repeated.

When in use, the grounding wire of equipment such as an electric welding machine and the like is fixed on the position 1 and is screwed and fixed by a nut; loosening the bolts at the 3 parts, placing the device 2 on the grounding flat iron of the main grounding ring network, tightly attaching the inner sides of the 2 parts to the grounding flat iron of the main grounding ring network, then screwing the 3 parts tightly, tightly attaching the device 2 to the grounding ring network, ensuring a good contact area, and starting construction operation after confirmation of completion.
