[0002] The dip-moulded balance compensation chain is a key component used in the elevator system, mainly used to compensate for the weight of the steel wire rope to ensure the smoothness and dynamic balance of the elevator during operation. As the name implies, the dip-moulded balance compensation chain covers a layer of plastic material on the surface of the chain through the dip-moulding process to achieve specific functions and effects. It usually consists of chain links, a galvanized layer and a dip-moulded layer. The chain links are buckled together to form a long chain. The galvanized layer is adsorbed on the surface of the chain links, and the dip-moulded layer is evenly coated outside the galvanized layer.

[0003] The existing technology chains are prone to rust after long-term use; the dip-moulded layer is not an environmentally friendly material, has poor weather resistance, and high energy consumption during the processing process;

[0004] The existing patent (Publication No.: CN204778161U) discloses a dip-moulded elevator balance compensation chain, which includes a dip-moulded layer, a galvanized layer and chain links. The chain links are buckled together to form a long chain. The galvanized layer is adsorbed on the surface of the chain links, and the surface of the galvanized layer is smooth, uniform and delicate; the dip-moulded layer is evenly coated on the surface of the galvanized layer to keep the shape of the metal light chain. It can not only effectively reduce the elevator operation noise, but also is green and environmentally friendly, not easy to rust, has a simple process, low production cost, convenient operation and long service life.

[0005] In view of the above problems, although the solution given by the existing patent can effectively reduce the elevator operation noise and is green and environmentally friendly, the balance compensation chain may still generate stress during use, and it cannot automatically release the stress, which requires subsequent manual release, increasing the subsequent maintenance cost. Summary of the Invention

One end of the balance chain wear-resistant shell is provided with a fixing piece, and an auxiliary mechanism for eliminating stress of the balance chain is fixed on the side wall of the fixing piece;

[0008] The auxiliary mechanism includes a connecting rod, which is fixed to the side wall of the fixing member. A fixed bearing is sleeved on the outer surface of the connecting rod, and a connecting member is fixed to the outer surface of the fixed bearing. One side of the connecting member is connected with a fixed block.

[0009] Preferably, a fixing bolt is threadedly connected inside the fixed block, and the end of the fixing bolt is threadedly connected with a threaded hole opened on the connecting rod.

[0010] Preferably, two fixing plates are symmetrically fixed to the outer wall of the fixed block, and mounting bolts are installed inside both of the two fixing plates.

[0011] Preferably, balls are installed on the inner wall of the fixed block, and the fixed block and the connecting member form a rotating structure through the balls.

[0012] Preferably, a sound-absorbing inner shell is fixed inside the wear-resistant shell of the balance chain.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4 , a plastic dipping type balance compensation chain with high flexibility, including a wear-resistant shell 1 of the balance chain.

[0028] The auxiliary mechanism includes a connecting rod 3. The connecting rod 3 is fixed on the side wall of the fixed part 2. A fixed bearing 32 is sleeved on the outer surface of the connecting rod 3. A connecting piece 31 is fixed on the outer surface of the fixed bearing 32. One side of the connecting piece 31 is connected with a fixed block 33. The connecting rod 3 and the connecting piece 31 form a rotating structure through the fixed bearing 32. A fixed bolt 34 is threadedly connected inside the fixed block 33. The end of the fixed bolt 34 is threadedly connected with a threaded hole 38 opened on the connecting rod 3. Two fixed plates 35 are symmetrically fixed on the outer wall of the fixed block 33. Installation bolts 36 are installed inside both of the two fixed plates 35. A ball 37 is installed on the inner wall of the fixed block 33. The fixed block 33 and the connecting piece 31 form a rotating structure through the ball 37.

[0029] By adopting the above technical solution, before using the dip-molded balance compensation chain with high flexibility, the balance compensation chain is first assembled. Through the fixing plate 35 provided on the fixing block 33, the fixing plate 35 can be fixed by the mounting bolt 36, and then the balance compensation chain and the elevator are assembled and connected. The other end of the balance compensation chain is fixed in the same way. Due to the fixed bearing 32 provided in the connecting member 31 and the threaded hole 38 opened on the connecting rod 3, the fixing block 33 and the connecting member 31 can be fixed by the fixing bolt 34. Due to the fixed bearing 32 provided in the connecting member 31, the balance compensation chain can rotate, thereby ensuring that the stress generated during the use of the balance compensation chain can be automatically eliminated, improving the practicability. Moreover, due to the balls 37 provided on the fixing block 33, the friction between the fixing block 33 and the connecting member 31 is avoided, which affects the rotation and ensures the stability.

[0030] Specifically, as Figures 1 - 4 shown, a sound-absorbing inner shell 4 is fixed inside the balance chain wear-resistant shell 1, a dip coating layer 5 is fixed inside the sound-absorbing inner shell 4, a balance chain body 6 is arranged inside the dip coating layer 5, and a galvanized layer 7 is coated on the outer surface of the balance chain body 6.

The provided sound-absorbing inner shell 4 can play a certain sound-absorbing effect to avoid generating excessive noise. The provided dip coating layer 5 wraps the balance chain body 6, thereby improving the flexibility of the balance chain. The galvanized layer 7 coated on the surface of the balance chain body 6 can play a role in protection and rust prevention, and has strong practicability.

[0032] Working principle: Through the fixing plate 35 provided on the fixing block 33, the fixing plate 35 can be fixed by the mounting bolts 36, and then the balance compensation chain and the elevator can be assembled and connected. The other end of the balance compensation chain is fixed in the same way. Due to the fixed bearing 32 provided in the connecting member 31 and the threaded hole 38 opened on the connecting rod 3, the fixing block 33 and the connecting member 31 can be fixed by the fixing bolt 34. Due to the fixed bearing 32 provided in the connecting member 31, the balance compensation chain can rotate, so as to ensure that the stress generated during the use of the balance compensation chain can be automatically eliminated, improving the practicability. And due to the balls 37 provided on the fixing block 33, the friction between the fixing block 33 and the connecting member 31 is avoided, ensuring the stability. The provided fixing member 2 fixes the balance chain body 6 and the connecting member 31, and the balance chain wear-resistant shell 1 can play a wear-resistant role, thereby increasing the service life. The provided sound-absorbing inner shell 4 can play a certain sound-absorbing effect. The provided dip coating layer 5 is wrapped around the balance chain body 6, thereby improving the flexibility of the balance chain.
