Introduction of ring chain for mining

RELEASE TIME :

2020-06-02

Mining ring chain called mining circular chain or circular chain, is mainly used for scraper conveyor, conveyor and shearer transmission chain.

Integration and failure analysis of mining ring chain

1. Qualified mining ring chain parts are: (1) withstand tension; (2) fatigue caused by pulsating load; (3) Friction and wear between the chain ring and the chain ring, between the chain ring and the sprocket, between the chain ring and the intermediate plate and the groove side; (4) Corrosion caused by pulverized coal, stone powder and humid air. 2. Failure analysis The fracture forms of mining ring chains can be roughly divided into: (1) the load of the chain exceeds its own static fracture load, resulting in premature fracture. This fracture mainly occurs in the shoulder or straight arm of the chain defect. , such as crack welding heat affected zone and single crack; (2) After running for a period of time, the chain has not reached the breaking load and breaks due to fatigue. This fracture occurs mainly at the straight arm and arc of the link.

Requirements for ring chains for mining

(1) In the same material and section, must have a high bearing capacity; (2) At the same time has a large fracture load, must have a large elongation; (3) Small deformation under load to ensure good meshing; (4) high fatigue strength; (5) High wear resistance; (6) High toughness, strong ability to absorb shock load; (7) The geometric size conforms to the requirements of the drawing.

What does mine ring chain need to notice?

This fracture occurs mainly at the shoulder or straight arm of the link, such as the heat affected zone of crack welding and the crack of a single steel bar. Before the chain reaches breaking load, it will break due to fatigue. This fracture mainly occurs at the junction of the straight arm and the chain joint arc.

Analysis of Chinese chain industry quality work

Since 2003, Chinese chain industry still maintains rapid development speed. In 2004, under the guidance of the state macro-control policy, the Chinese chain industry changed the previous development thinking of heavy production and heavy market, adjusted and optimized the product structure, and gradually realized the transformation of economic growth mode. At the same time, Chinese chain industry has been developing high-tech content and high value-added new products, improving product quality and enhancing the competitiveness of Chinese chain industry in the international market as an important development strategy of enterprises. In recent years, in the chain drive association, chain drive standardization technical committee, the national chain quality supervision

The chain driving mechanism includes a chain

The utility model relates to a chain drive mechanism on a NC drilling machine used for blind hole processing in a perforating gun barrel. The utility model relates to a chain drive mechanism to solve the problem that the distance between the cutter head and the main sprocket on the NC drilling machine used for blind hole processing in a perforating gun barrel is long, and the single chain drive is easy to loosen and break the chain. The transmission motor drives the transmission pair gear to rotate through the transmission gear shaft and the transmission main gear, and the main sprocket shaft then rotates and drives the main sprocket to rotate. The chain drive and the centralized heating mechanism of the plastic bottle blowing machine, the chain drive mechanism comprises a chain and a number of transmission gears, the chain is fixed with a number of chain block components, including the chain block, each chain block

Force analysis and structure optimization of connecting link

The connecting link is the connecting part of the scraper chain of coal mine scraper conveyor, which plays an important role in the traction chain. Due to the special working conditions, traction chain link often occur fracture phenomenon, once the chain link is broken, the whole equipment is in a state of paralysis, seriously affecting the normal production of coal mine. Not only the economy suffered serious losses, but also the search for the broken chain and link are carried out on the side of the coal wall, there is a certain risk, and even cause personal accidents. The connecting link has a high breaking capacity, and a high reliability is required in the work. So the study of connecting link link change. Previous analyses of the butt link did not consider the effect of the cylindrical pin, and
