摘要:
侧边带有双排联网钩的菱形金属网适用于厚煤层分层综采机械铺联网、或高挡普采、炮采工作面用做人工假顶。它是在编网时,在网片侧边的丝头弯成双排联网钩。在铺网时,网片侧边联网钩与相邻网片侧边上相对应的网孔勾联,并压倒和压实联网钩,联网可靠强度高、省工、省时。
摘要(英):
The utility model relates to a rhombic metal net with side having double rows net-connecting hook, and is suitable for a slicing comprehensive mining machinery to pave and couple a net in thick coal seam, or being used as an artificial roof in the working face of ordinary mining and blast mining. When in net braiding, spinning heads on the side edge of a net sheet are bent to form two row net-connecting hooks; when in net paving, the net-connecting hook in the side edge of the net is connected by hooking with a corresponding net hole on the side edge of an adjacent net sheet, and the net-connecting hook is pressed down and compacted. The utility model has the advantages of high strength, labor saving and time saving.
