Embodiment Construction

[0019] To make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, below in conjunction with the attached Figure 1 ~ Figure 4 The present invention will be further described in detail with specific embodiments.

[0020] The elevator composite hoisting belt adopted in this embodiment is installed in the elevator hoisting mechanism, such as figure 1 As shown, the elevator hoisting mechanism is mainly composed of a composite lifting medium 2 connecting a car 1 and a counterweight 4 through a traction machine 3 . The composite lifting medium 2 is a flat strip, such as figure 2 As shown, in the elevator hoisting mechanism, one side of the surface is attached to the traction machine 3, and the rotation of the traction machine 3 is converted into the linear motion of the composite lifting medium 2 through friction with the composite lifting medium 2, and then the traction force is transmitted to The car 1 realizes the li...

Abstract

The invention discloses a special steel wire rope for an elevator composite lifting belt, and relates to the field of elevator composite lifting belts. The steel wire rope is composed of a central strand and an outer layer strand which surrounds the central strand, and the central strand and the outer layer strand comprise 65 steel wires. Compared with a traditional elevator composite steel stripsteel wire rope, the steel wire rope is lower in cost; the single breaking tensile force reaches 5000N or above, and meanwhile, the steel wire rope has better anti-fatigue performance. An adhesive layer is arranged on the outer surface of the steel wire rope, so that the bonding stability of the steel wire rope and a polyurethane coating layer in a composite steel strip is guaranteed. The specialsteel wire rope for the elevator composite lifting belt is formed by twisting the steel wires with two kinds of diameters at most, and the process complexity is reduced.

Description

technical field [0001] The invention relates to the field of elevator composite hoisting belts, in particular to a special steel wire rope for elevator composite hoisting belts. Background technique [0002] Currently, skeleton wire ropes used in elevator composite hoisting belts need to meet extremely high standards. Due to the high safety requirements of the elevator, the composite hoisting belt is subjected to repeated bending during the elevator's operating life. As the main load-bearing material of the composite hoisting belt, the steel wire rope must have extremely high fatigue resistance. And because the outer layer of the steel wire rope in the composite lifting belt is coated with polyurethane, the steel wire rope also needs to maintain stable adhesion with polyurethane throughout the life cycle. [0003] In 1999, Otis Elevator Company first disclosed a flat belt-shaped lifting medium in PCT / US1999 / 019267, and it has been used so far. The invention uses a 7x7 stru...
