ASSEMBLY TEMPLET FOR UNDERGROUND STEEL PROPPING

摘要

The assembly pattern is intended for underground mine construction for adjustment of mine preparations. It enhances productivity, security and safety and removes the manual labor. The pattern consists of three pairs of metallic segments (1-6), connected in between through transversely located plates (7, 8 and 9). On the intermediate connecting plate (8), an apple-shaped bolt (10) is fitted. Below it sits a flange (11) with a cog front surface. To the external (13) and internal (12) feathers of the metallic segments (1-6), locking mechanisms are fitted.<IMAGE>
