Assembled steel band for elevator tractors

Abstract

The invention discloses an assembled steel band for elevator tractors. The assembled steel band is characterized in that the assembled steel band for the elevator tractors comprises a surface layer, a middle layer and a bottom layer. A plurality of steel wires are arranged in the middle layer; side edges of the surface layer and the bottom layer respectively extend along the side surface of the middle layer to respectively form a surface layer extension portion and a bottom layer extension portion; and the surface layer extension portion is detectably connected with the bottom layer extension portion. The assembled steel band for the elevator tractors is easy to maintain and low in use cost.

Description

technical field [0001] The invention relates to an elevator traction machine, in particular to an assembled steel belt for the elevator traction machine. Background technique [0002] At present, with the increasing number of high-rise buildings, the demand for high-speed elevators is gradually increasing. Most elevator manufacturers in my country provide elevator traction and hoisting to the market using steel wire ropes for elevators. After long-term use, it is found that the There are still many deficiencies in the use of the product, as follows: [0003] 1) Since the wire rope is easy to swing during use, the elevator is noisy during operation; [0004] 2) In order to reduce the wear of the steel wire rope, lubricating grease is usually coated on the steel wire rope. Since the steel wire rope swings greatly during use, the lubricating grease in the steel wire rope will splash out and pollute the machine room; [0005] 3) After the steel wire rope has been used for a per...

AI Technical Summary

Problems solved by technology

[0003] 1) Since the wire rope is easy to swing during use, the elevator is noisy during operation;

[0004] 2) In order to reduce the wear of the steel wire rope, lubricating grease is usually coated on the steel wire rope. Since the steel wire rope swings greatly during use, the lubricating grease in the steel wire rope will splash out and pollute the machine room;

[0005] 3) After the wire rope has been used for a period of time, there will be broken wires and strands, which will cause the elevator to vibrate and shut down, resulting in an increase in the maintenance cost of the elevator

[0006] Due to the existence of the above shortcomings, more and more elevator traction lifts begin to use steel belts to replace the role of steel wire ropes. However, because the existing steel belts are an integral structure, when any part is worn or cracked, it will Resulting in the entire steel belt being unusable
