Steel wire rope type balance and compensation cable for elevator

Abstract

The invention provides a steel wire rope type balance and compensation cable for an elevator. The cable comprises high-strength soft steel wire ropes, a soft elastic inner layer, a braid and a soft elastic outer cladding, wherein the steel wire ropes are arranged in the inner layer; the braid is arranged on the surface of the inner layer; and the outer cladding forms a whole on the surface of the braid. Compared with the prior art, the cable has the following advantages: the cable has reasonable structure, high bearing load under the condition of the same weight per unit length, good flexibility and good suspension perpendicularity, is flexible in bending, is not easy to crack or fall off, can effectively remove the noises during using the elevator, prolong the service life and improve the safety property of the elevator and has simple manufacturing process and cost lower than that of the presently used compensation cables.

Description

technical field [0001] The invention relates to an elevator balance compensation cable, in particular to an elevator balance compensation cable used in high-speed (elevator speed greater than 3m / s) elevators. Background technique [0002] The elevator balance compensation cable is used to connect the elevator car and the counterweight, mainly used to balance the weight of the traction rope, and to balance and compensate the operation of the elevator. It is required to have the characteristics of large load bearing, low running noise, suitable weight per unit length, and flexible bending. [0003] The chains currently used for elevator balance compensation have the following deficiencies: first, metal light chains are used to thread the ropes. During the operation of the elevator, the chains collide with each other, the noise is loud when the elevator is in use, and the chains are easy to rust; It is a layer of plastic cover on the metal light chain. Although the impact of t...

Problems solved by technology

[0003] The chains currently used for elevator balance compensation have the following disadvantages: first, metal light chains are used to thread the ropes. During the operation of the elevator, the chains collide with each other, the noise is loud when the elevator is in use, and the chains are easy to rust; It is a layer of plastic cover on the metal light chain. Although the impact of the chain link is slowed down, the plastic cover of the compensation chain is easy to crack and fall off, and the service life is short; the third is to add a layer of rubber and plastic material on the metal light chain, and the shape is round. , the suspension verticality of the compensation chain is not enough during the operation of the elevator, it is easy to twist, it is easy to generate noise during operation, and the running comfort is poor; Fourth, the above several compensation chains are all used in elevators with a lifting speed of less than 3m / s, which is not applicable at present High-speed elevator requirements restrict the development of domestic elevators
