Flat link for mining is also called chain link or block link on the market, which can only be used for flat link. In terms of design, flat link adopts a special design for the special structure of sprocket wheel, greatly increasing the thickness of the vulnerable parts of the link, thus greatly improving the service life of the link. In addition, it is fixed by a locking bolt, which is very convenient for installation and disassembly.
It is mainly used for the connection of the chain head and tail vertical ring between the mining ring chain specified in GB / t1218 and the mining high strength compact chain specified in MT / T 929 used by the scraper conveyor, transfer machine and coal plough in the coal mine. The standards for product design, manufacturing and inspection are MT / t99-1997 flat link for mining chain, MTT 463-1995 flat link inspection specification for mining chain and Q / aid01-2013 flat link technical specification for mining.
Process design of chain link
In order to connect the reinforced mining chain and have the corresponding strength, the chain link is designed specially. The strength of the link is 25% higher than that of the ring chain or flat chain of DIN standard grade 2. Through careful selection of materials and special heat treatment process, the performance of this reinforced chain connecting ring meets the second part of din2258:2003 standard. This type of connecting link can only be installed and used on the horizontal plane. The installation specification design makes the chain and sprocket wheel mesh safely.
