Elevator traction belt and elevator

Abstract

The invention discloses an elevator traction belt and an elevator with the traction belt. The traction belt comprises a wrapping layer and at least one bearing body sleeved with the wrapping layer. Each bearing boy comprises basalt fibers and a resin matrix which are compounded together. The basalt fibers comprise multiple parallel basalt fiber filaments. Due to the fact that density of the basalt fibers and the density of the resin are both smaller than that of a steel wire, the weight of the traction belt is effectively reduced, the traction belt can be easily used on the elevator with superlarge lifting height, and the range of an existing maximum elevator lifting height can be widened. Meanwhile, the basalt fibers have a good sound absorption effect, the traction belt is made from the basalt fibers, noise generated during operation of the traction belt can be effectively lowered, and elevator taking comfort is improved. The basalt fiber filaments are arranged in the resin matrix in parallel, friction force among the fiber mono-filaments is reduced, the traction belt has the advantages of being free of twisting, resistant to abrasion, resistant to fatigue and the like, the traction performance of the traction belt is improved, and the service life of the traction belt is prolonged.

Description

technical field [0001] The invention relates to the technical field of traction elevators, in particular to an elevator traction belt and an elevator. Background technique [0002] The traction medium of traditional elevators is generally steel wire rope, which is made of twisted and jointed steel wires. The density of the steel wire rope is relatively high. As the lifting height of the elevator continues to increase, the weight of the steel wire rope will cause the weight of the elevator system to be too large, requiring the drive host to provide a larger Shaft load and torque make the elevator system consume a lot of energy, which greatly increases the design cost of the elevator; at the same time, the steel wire rope has poor weather resistance and needs to be lubricated with a certain amount of oil. The elevator needs regular maintenance during use, and the maintenance cost is high. And it is not conducive to environmental protection. [0003] In addition, some elevator...

AI Technical Summary

Problems solved by technology

Although the density of the traction belt is reduced, the fiber adopts a braided structure, and friction and wear between the fiber monofilaments are easy to occur, which affects the service life of the carrier

In addition, other fibers such as carbon fiber have no sound-absorbing effect. When the traction belt runs at high speed, it is not conducive to noise control and affects the comfort of the elevator.
