High strength lifting chain in industry, construction, machinery industry is an essential part, in the use of high strength lifting chain to pay attention to their own safety, as well as the safety of people around, let's talk about the use of high strength lifting chain should be used First of all, we have to check the inside/outside chain piece has no deformation, cracks, embroidery corrosion, and so on, and then check the dowel has no deformation or rotation, roller is crack, damage, excessive wear; Finally, check whether the joint of the key bar is loose and deformed.

First of all, we have to check the inside/outside chain piece has no deformation, cracks, embroidery corrosion, and so on, and then check the dowel has no deformation or rotation, roller is crack, damage, excessive wear; Finally, check whether the joint of the key bar is loose and deformed.

If the high strength lifting chain in use when running abnormal sound or abnormal vibration, immediately stop using, immediately check whether the lubrication condition of the chain is good, if the lubricating oil is too little, add lubricating oil, and then work.

Before each high strength lifting chain is used, precision measurement should be carried out otherwise it cannot guarantee the safety of construction personnel and construction site personnel. Before the measurement to clean the chain, and then the lifting chain around the two sprockets, lifting chain on both sides should have a certain support. Before measurement, 1/3 of the lifting chain should be applied, and the stability of the lifting chain should be tested for one minute under the state of minimum tensile load. This is to remove the clearance of the whole chain, so as to increase the accuracy of measurement.

And in the measurement, should be imposed on the lifting chain a certain amount of measurement load, so that the upper and lower sides of the chain tightening, the chain in the sprocket should ensure the normal engagement state, the final measurement of the center distance between the two sprockets. Measure chain elongation.

It is worth noting that when measuring the lifting chain, in order to reduce more errors, should be selected in the 6-10 section of the place measurement.

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
