Embodiment 1

[0040] Such as figure 1 As shown in the figure, the traction rope for the elevator device shown in the figure is composed of an elastic body 1 constituting the main body of the traction rope and six independent bearing bodies 2. The cross section of the elastic body is circular, and the non-metallic elastic Material, specifically polyurethane rubber.

[0041] Six independent carriers 2 are directly embedded in the elastic body 1 and are completely covered by the elastic body 1 . Considering the isotropy and compact structure of the traction rope, the six independent bearing bodies 2 are evenly distributed on the same circumference, and the angle formed by the center of the adjacent independent bearing body 2 and the center of the elastic body 1 is 60° .

[0042]Each independent carrier 2 is made of metal material, specifically, each independent carrier 2 is made of high-strength carbon steel wire twisted into a steel wire rope with a diameter of 0.5mm-3.5mm, specifically 1+9...

Embodiment 2

[0046] In order to increase the breaking force of the traction rope and provide support for the independent carrier 2 of the outer layer, such as figure 2 As shown, all the independent carriers of this embodiment are distributed in two layers of concentric circles in the radial direction in the elastic body 1, and the independent carriers of each layer are evenly spaced on the same circumference. Considering the compactness of the structure, the independent The diameter of the carrier body 3 is smaller than the diameter of the independent carrier body 2 of the outer layer, and every adjacent two independent carrier bodies 3 in the independent carrier body 3 that are evenly spaced on the same circumference of the outer layer form a trough with the center of the cross section of the elastic body 1, The independent carriers 2 in the inner layer that are evenly spaced on the same circumference fall into these troughs respectively.

[0047] The distance d from the center of each i...

Embodiment 3

[0049] Such as image 3 As shown, the difference between the traction rope for the elevator device of this embodiment and Embodiment 1 and Embodiment 2 is that the elastic body 1 is made of neoprene rubber reinforced with nylon short fibers, which can enhance the wear resistance of the elastic body, and can Effectively prolong the service life of the traction rope.

Abstract

The invention discloses a hoisting rope for an elevator device. The hoisting rope is formed by an elastic body forming a hoisting rope body and a plurality of independent bearing bodies arranged in the elastic body and parallel to the hoisting rope body. The hoisting rope is of a round structure, tension exerted on the rope is focused in a small dimension, and uneven stress of a flat stretching member in the width direction and eccentric abrasion caused by the uneven stress are avoided. The hoisting rope has the advantage that the service life of a hoisting wheel and the independent bearing bodies in the hoisting rope is prolonged due to the fact that the abrasion-resistant elastic body wraps the surfaces of the plurality of independent bearing bodies compared with a traditional hoisting rope; the diameter of the hoisting wheel is reduced, rotating torque of an elevator main machine is reduced, the size of the main machine is reduced, and manufacture cost and building cost of the main machine are reduced accordingly; the hoisting rope is not twisted during installation by means of symmetrical distribution of the independent bearing bodies, and installation quality and elevator operation quality can be improved.

Description

technical field [0001] The invention relates to a traction rope used in an elevator system. Background technique [0002] A traditional traction elevator system includes a traction machine, a car and a corresponding counterweight, and more than two traction ropes suspended on the traction machine to support and drive the car and the counterweight. The traction rope is a supporting and transmission safety component in the traction elevator system, and its performance directly determines the safety of the elevator operation. Due to economy and excellent performance, natural hemp core wire rope is usually used as traction medium. However, traditional steel wire ropes have some disadvantages and limitations. [0003] Generally, the traction sheave is made of cast iron. The unbalanced friction and wear between the steel wire rope and the cast iron often leads to premature scrapping of the traction sheave or the steel wire rope. At the same time, the elevator wire rope has a h...
