Problems solved by technology

[0002] At present, the chains used for elevator lifting balance compensation: one is to use metal light chains. During the operation of the elevator, the chains directly collide with each other, making noise and easy to rust; second, the metal light chains are covered with a plastic layer. It can slow down the impact between the chains, but the plastic sheath of this kind of compensation chain is easy to crack and fall off, and the service life is short; the third is to wear hemp rope or copper wire rope between the metal light chains, and the compensation chain is easy to twist during operation. Loud noise and poor security

Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] Such as figure 1 As shown, the new type elevator balance compensation chain includes a metal chain 1, the outside of the metal chain 1 is wrapped with a wrapping layer 2, and the outside of the wrapping layer 2 is provided with an outer sheath 3, and the outside of the outer sheath 3 A fiber layer 4 is provided. Wherein, the outer sheath 3 is a PVC composite material layer. In this embodiment, because the fiber layer has excellent low temperature resistance, it maintains its softness in a low temperature environment and achieves a good balance compensation effect. It is suitable for elevators with a speed of 3 to 4 m / s, and the ambient temperature is -50 ° C to 60℃, long service life.

[0010] Finally, it is noted that the above embodiments are only used to illustrate the technical solution of the present invention without limitation, other modifica...

Abstract

The invention relates to the technical field of elevator parts, particularly to a novel elevator balance compensation chain which comprises a metal chain, wherein the metal chain is wrapped with a coating layer; an outer sheath is arranged outside the coating layer; a fiber layer is arranged outside the outer sheath. With the structure, the novel elevator balance compensation chain has the advantages of high strength, good elasticity, flexibleness, abrasion resistance and low temperature resistance and wide temperature adaptation range, can maintain flexibleness in a low-temperature environment to achieve a favorable balance compensation effect, is suitable for elevators at the speed of 3-4 m / s, is adapted to the environmental temperature of -50 to 60 DEG C and has a long service life.

Description

technical field [0001] The invention relates to the technical field of elevator accessories, in particular to a novel elevator balance compensation chain. Background technique [0002] At present, the chains used for elevator lifting balance compensation: one is to use metal light chains. During the operation of the elevator, the chains directly collide with each other, making noise and easy to rust; second, the metal light chains are covered with a plastic layer. It can slow down the impact between the chains, but the plastic sheath of this kind of compensation chain is easy to crack and fall off, and the service life is short; the third is to wear hemp rope or copper wire rope between the metal light chains, and the compensation chain is easy to twist during operation. Loud noise and poor security. Contents of the invention [0003] The purpose of the present invention is to provide a new elevator balance compensation chain with reasonable design, simple structure, good...
