High strength mine ring chain and compact chain link are the key components of mine scraper conveyor. It's also the weakest link in the whole machine. It not only bears frequent impact loads, but also comes into direct contact with the material.

High strength mine ring chain and compact chain link are the key components of mine scraper conveyor. It's also the weakest link in the whole machine. It not only bears frequent impact loads, but also comes into direct contact with the material.
Improvement measures of ring chain used in mine
In order to realize the high reliability and long life of the mine ring chain operation, it is necessary to do a good job in the repair and maintenance of the chain link, in order to ensure the normal operating environment of the chain link and avoid the abnormal stress of the chain link, among which it is essential to ensure the normal engagement of the ring chain, the chain link chain and the sprocket.
The meshing relationship between the chain, sprocket, and link is constantly changing as it wears out during use. In the operation and maintenance of the equipment, attention should be paid to the three operating conditions. If the ring chain and chain link for mining do not mesh properly, the reason should be carefully analyzed. If necessary, replace the chain link or sprocket. If there are frequent outages due to chain breaks, it will be necessary to replace all chains and sprockets.
Other matters needing attention in the repair and maintenance of mine ring chain
1. Ensure that the ring chain for mining is installed in the correct direction. Install the gasket in the correct position and mark the position with a straight line. At the same time, do not insert any parts between the connecting links
2. If there are bolts on the ring chain, ensure that the bolts are in the correct position and locked state.
3. Check the mine ring chain regularly to avoid accidental damage and corrosion of the influence of the strength of the butt link, timely replace the damaged link, prevent chain breaking and shutdown accidents, and avoid the damage of the broken chain to the whole machine.
4. The manufacturing quality of mining ring chain is one of the causes of chain fracture accidents. For example, in the design of the link, there are material jerry-cutting or processing technology problems, or in the processing of the link, there are impurities and other manufacturing quality problems, these will lead to scraper operation accidents. It is recommended that coal mining enterprises put equipment into storage, choose high-quality link products and forbid people to store unqualified products.

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
