As an example, the balance chain of an elevator is demonstrated for demonstrating this invention.

In general, the balance chain of the elevator is connected to each other at the bottom of the elevator cage and the bottom of the count weight, as shown in Figure 6, the top of the elevator cage when the elevator cage is moved to the top or bottom Compensation for the weight imbalance caused by the movement of the wire rope connected to the top of the and the count weight.

However, the balance chain of the elevator is made of a metal ring and the ring is connected, so if the elevator cage moves up or down, the balance chain is moved accordingly, the ring and the ring of the balance chain hit each other to generate noise.

In order to solve the above problems, the prior art is typically used 1) rope insert link chain, 2) synthetic resin shrink coated link chain, and 3) synthetic resin immersion coated link chain.

By the way, 1) the rope insertion type link chain is to prevent the occurrence of noise by passing the manila rope between the ring and the ring of the link chain as shown in Figure 7 to prevent the collision between the ring and the ring, but the manila rope Since the work between the link chain and the link is purely done by hand, it takes a lot of labor, and during the above operation, manila powder is blown from the manila rope, which not only harms the health of the workers, but also links the manila rope. During the work put into the ring of the chain to prevent the corrosion of the link chain, the coated asphalt layer is peeled off due to friction with the manila rope, causing the corrosion.

And, 2) the synthetic resin shrink-coated link chain is a synthetic resin coating on the link chain by cooling the molten synthetic resin coated on the link chain, as shown in Figure 8, the work process for coating the synthetic resin on the link chain is simple And the raw material cost is relatively inexpensive, but due to the frequent movement of the link chain, the coating of the ring and the connecting portion of the ring is easily peeled off, there was a problem that excessive damage to the coating caused by the change in winter temperature.

In addition, the 3) synthetic resin immersion-coated link chain is formed so that the link chain is embedded in the cylindrical synthetic resin as shown in Figure 9 has a strong and semi-permanent advantage, but the synthetic resin is consumed a lot and is now entirely dependent on imports Therefore, the price is expensive, the bending radius is large, it is difficult to fix the elevator cage, there was a problem such as giving a strong impact to the surrounding structure due to irregular movement during installation and running.

Accordingly, the present invention is to solve the problems described above, it is easy to install on the link chain, easy to maintain, provides an elevator balance chain and industrial link chain coupling sphere excellent in noise prevention effect and safety. There is a purpose.
