Description

Technical Field

[0001] The utility model relates to the technical field of compensation chains, in particular to a high-stability wear-resistant elevator compensation chain. Background Technique

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. Generally, elevators with a lifting height exceeding 30m will use a compensation chain, whose structure is a steel chain wrapped with a rubber composite material, used to compensate for the weight of the steel wire rope and make the elevator run smoothly. When the elevator is at the top floor, the steel wire rope is on the counterweight side, and the counterweight side has the extra weight of the steel wire rope; when the elevator is at the bottom floor, the steel wire rope is on the car side, and the car side has the extra weight of the steel wire rope. Installing a compensation chain can balance this part of the drop and is used to compensate for dynamic balance. Because the steel wire rope has weight, with the continuous up and down movement of the elevator, dynamic imbalance will occur, so the compensation chain is used.

[0003] When the existing high-stability wear-resistant elevator compensation chain is actually used, although the noise during the operation of the compensation chain has been greatly reduced, its flexibility and durability still need to be improved, which is not conducive to increasing the service life of the compensation chain.

[0004] After searching for existing patents: A high-stability elevator balance compensation chain (publication number: CN212050056U), this utility model discloses a high-stability elevator balance compensation chain. Card slots are respectively opened on both sides inside the lock ring. Block pieces are arranged in the card slots on both sides inside the lock ring, and the block pieces are fixed on both sides of the lock ring through bolts. Two lock rings are connected to each other. Roller columns are also arranged at both ends inside the lock ring at the connection part. After the connection, the outside of the lock ring is wrapped with a rubber composite layer. The structure of this utility model is reasonable. There will be no torsion between adjacent lock rings, avoiding the deformation and tumbling of the lock rings, thus ensuring the stability of the elevator. It will not be like the traditional compensation chain where adjacent lock rings collide with each other and there will be no friction on the inner side of the lock ring, thereby increasing the service life of the elevator balance compensation chain. With the cooperation of the external rubber composite layer, the elevator balance compensation chain will not have the situation that the other two lock rings connected to one lock ring are on the same side, thus ensuring that the overall length of the elevator balance compensation chain is always maximized and also ensuring the stability of the elevator.

[0005] Although the above patent achieves the situation that the other two lock rings connected to one lock ring are not on the same side, there will be vibrations and uneven wear during the lifting and lowering process of the compensation chain, causing the compensation chain to sway back and forth, resulting in abnormal noises or unstable operation, which is not conducive to improving the stability of the compensation chain.

For the highly stable and wear-resistant elevator compensation chain, through the settings of the wear-resistant layer, the protection component and the flexible steel wire rope, when the compensation chain is used for a long time and during the ascending or descending process, wear will occur, which affects the service life of the compensation chain.
