High strength lifting chain in the crane lifting large heavy engineering operation is essential, but also vital, high strength lifting chain is related to the taking device to improve the efficiency of the crane, the problem of expanding the efficiency of the crane plays a vital role. It is mainly used in the crane or other lifting equipment above, is one of the important lifting rigging lifting and pulling work. At present, it has been widely used in manufacturing, construction, transportation and other fields.
High strength lifting chain in the crane lifting large heavy engineering operation is essential, but also vital, high strength lifting chain is related to the taking device to improve the efficiency of the crane, the problem of expanding the efficiency of the crane plays a vital role.
It is mainly used in the crane or other lifting equipment above, is one of the important lifting rigging lifting and pulling work. At present, it has been widely used in manufacturing, construction, transportation and other fields.
Because of the high strength lifting chain work industry, many are high-risk industries, so how to ensure the safety of the people around the operation process is also very important, once the high strength lifting chain appears in this situation, must be timely replacement of the new lifting chain, otherwise there will be irreparable consequences.
1. The allowable wear value of the lifting chain shall not exceed 10% of the diameter of the ring chain rod or the thickness of the auxiliary tools;
2. Starting from the plane of the main ring that does not bend, if the main ring bends more than 10 degrees, the lifting chain should be abandoned and no longer used;
3. Any part of the lifting chain crack phenomenon, bending or twisting phenomenon and ring hinge between the stuck or stiff astringency, unable to rotate phenomenon, and artificial can not be excluded, prohibited the use of the lifting chain.
4. The permanent elongation of lifting chain and single ring shall not exceed 5% of the original length. If the deformation degree is too large, heavy loads cannot be safely loaded and accidents may occur.
5 If the lifting chain use time is too long, wear is very serious, has been unable to normal and gear mesh, but also immediately replace the new lifting chain.

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
