Characteristics and maintenance methods of high strength lifting chain

RELEASE TIME :

2020-09-19

High strength lifting chain is an indispensable lifting lifting machinery and equipment, for expanding the scope of work, improve the speed of work has a very great effect. High strength lifting chain is the use of the world's most excellent chain making machinery and equipment and the most excellent chain making process, using the world's highest quality alloy steel, referring to DIN5685, EN818-2, GB/T12718, GB/T20946 and other specifications manufacturing, its category is: Φ 6-48, can also be made according to user requirements of different diameters of high strength lifting chain.

Characteristics of high strength lifting chain:

★ Application: sling chain, hoist chain reuse, hanging beam;

Raw materials: high quality alloy steel;

★ Surface: polishing, blackening, dipping paint, spraying, hanging plastic, hot dip zinc, electroplating process, dacro;

Manufacturing specifications: ISO, DIN, BS, JIS, GB*;

★ Compressive strength level: 100, 80, 70, 63, 50, 40 *;

★ Safety guarantee: 4 times safety performance, 2.5 times test load *;

★ Product identification: link surface gum "ZC" or product model *;

★80 grade to ring chain each 1 is a unique serial number, printed in the ring chain sealed on the end of the identification plate;

High strength lifting chain maintenance methods:

1. Sprocket chain mounted on the shaft should not tilt and shake. In the same transmission system components of the two sprocket chain ports should be located in the same plane, sprocket chain core distance within 0.5 meters, tolerance error of 1 mm; When the core distance of sprocket chain is above 0.5 m, the tolerance error is 2mm. But do not allow friction sprocket chain tooth side problem, if the two wheel braiding shift is too easy to lead to slip chain and speed up the damage. Be sure to check the adjustment deviation regularly when removing and replacing the sprocket chain.

2. The tightness of the lifting chain should be suitable, too tight to increase the output power consumption, rolling bearing is easy to damage; Very loose chain is prone to quiver and slip. The tightness level of the chain is: put forward or pressed down from the middle of the chain, and the core distance of the two sprocket chain is about 2%-3%.

3. The new lifting chain is too long or extended after application, can not be adjusted, depending on the situation to remove the chain segment, but be sure to be even. The chain segment needs to cross from the opposite side of the chain, the lock piece is inserted outside, and the opening of the clamping piece should be the opposite direction of the rotation.

4. After the sprocket chain is seriously damaged, the new sprocket chain and the new chain should be dismantled at the same time to ensure excellent meshing. It is not possible to replace the new chain or sprocket chain independently. Otherwise it will cause the meshing is not very good and accelerate the damage of the new chain or the new sprocket chain. Sprocket chain tooth surface damaged to the corresponding level should be immediately turned over to apply (refers to the adjustable surface application of sprocket chain). To increase the usage time.

5. The old lifting chain can not be mixed with part of the new chain application, otherwise it is very easy to cause impact in the transmission system, pull the chain.

6. The lifting chain should remember to fill lubricating oil immediately in the work. The lubricating oil must enter the matching gap between the roller and the inner sleeve in order to improve the working conditions and reduce damage.

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
