Each group of the second metal chain comprises 3 large chain rings and 1 small chain ring, and each group of the chain rings is sequentially and mutually fastened and connected according to the arrangement sequence of the 2 large chain rings, the 1 small chain rings and the 1 large chain rings. The invention designs a conventional single metal chain into a combination of two sub metal chains so as to improve the load bearing capacity of the elevator balance compensation chain and ensure that the elevator balance compensation chain is not easy to twist.
As another example, chinese patent CN102242508A discloses a braided elevator balance compensating cable, which comprises a high-strength soft steel wire rope, a soft elastic inner layer and a braided layer, wherein the steel wire rope is arranged in the inner layer, and the steel wire rope and the braided layer form a whole on the surface of the inner layer. The high-strength chain ring is arranged between the inner layer and the braiding layer, wherein the braiding layer is directly braided or wound on the surface of the chain ring to form a whole; the inner layer is also provided with metal particles. The steel wire rope is a stainless steel wire rope, a polished steel wire rope or a galvanized steel wire rope, and the number of the steel wire ropes is single or multiple.

Specifically, in order to enhance the connection strength of the snap-in connection of the anchor chain 1, the chain ring 3 has a tapered structure, and the end of the movable rod 33 is thicker than the end of the vertical rod 32. In the use process of the elevator balance compensation chain, the stress points between the chain links are positioned at the connecting positions of two adjacent chain links, when the buckle type connecting structure is used, if the thickness degree of the whole chain link is the same, the connecting positions between the two chain links can be easy to deform and bend, so that the chain links fall off, and the chain link 3 is designed into a cone-shaped structure, the movable rod 33 end is thickened, the stress points are concentrated at the movable rod 33 end after the movable rod 33 is sleeved on the vertical rod 32, the strength of the chain link 3 is enhanced, and the bending and falling off of the chain link 3 are avoided.
Further specifically, the movable rod 33 includes a movable body 331 and two connection ends 332, the two connection ends 332 are respectively connected with the upper and lower cross bars 31, the movable body 331 is located between the two connection ends 332, the two connection ends 332 are provided with a torsion device, and the torsion angle of the torsion device is 0-90 °. The movable body 331 is of a hollow structure in the middle, the hollow part in the middle is spherical, and the movable body 331 is in a geometric body with a smooth surface. In the actual use process, in order to avoid the anchor chain being too stiff to be hung and bent, the anchor chain is usually designed into an independent movable chain ring, and the chain ring is connected with the chain ring end to end and has mobility; however, the excessive movement range can cause the loose slipping between the chain links, which can cause the elevator balance compensation chain to generate noise and twist easily during operation. In the invention, when the movable main body of the movable rod is sleeved with the vertical rod of the previous chain ring, the vertical rod is in a cylindrical structure, and the movable main body is in a spherical structure with a hollowed-out middle, and the vertical rod can rotate at a large angle in the movable main body, so that the invention designs the torsion device at two connecting ends, and limits the rotation angle of the movable main body 331 to a certain extent. Through experimental researches by those skilled in the art, when the torsion angle of the torsion device is set to be 0-90 degrees, the anchor chain can be ensured to have certain suspension flexibility, and the slipping between the chain links of the anchor chain can be effectively avoided.
