Composite type rope and production process thereof

Abstract

The invention provides a composite type rope. The composite type rope comprises a carbon fiber rope core composed of a plurality of carbon fiber bundles, and an aramid fiber layer wrapping the carbon fiber rope core. The carbon fiber rope core is formed in a twisting mode and comprises two or more carbon fiber bundles. The aramid fiber layer is of a net structure formed by weaving a plurality of aramid fiber ropes. The rope core of the composite type rope is the carbon fiber rope core, the external wrapping layer is composed of aramid fibers, carbon fibers have the tensile property so that the tensile property of the composite type rope can be improved, and wear of the carbon fibers can be prevented due to the wear resistance of the aramid fiber layer. Meanwhile, the carbon fibers have the self-lubricating property and do not need to be lubricated independently, so that the rope is convenient to maintain. The invention further discloses a production process of the composite type rope. The production process is simple and high in operability, and can effectively prevent the carbon fibers from being broken in the processing process.

Description

technical field [0001] The invention relates to the technical field of ropes, in particular to a composite rope and its production process. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take people or carry goods. In the current urbanization process is getting faster and faster, urban land area is in short supply, high-rise buildings Emerging continuously, the elevator has become a very important auxiliary tool in people's life, and its safety and comfort during use, and the economy of elevator operation have received more and more attention from users. [0003] The lift of the elevator is usually pulled by a steel wire rope. The steel wire rope is a flexible rope twisted with multiple or multiple thin steel wires. the rope. In material handling machinery, it is used for lifting, pulling, tensioning and carrying. [0004] The rope core of the steel wire ...

AI Technical Summary

Problems solved by technology

Although the steel core can increase the strength, its unique physical characteristics make it too rigid to break easily, and it is easy to be stretched. A sudden change in speed during use will cause a certain elongation of the steel wire rope, which will cause a certain amount of elongation in the elevator. The phenomenon that causes the elevator to plummet

[0005] The steel wire rope needs to be lubricated during use. Generally, the steel wire rope is oiled once every 4 months. When oiling, it is best to soak the rope core with hot oil (about 50°C), and then wipe off the excess grease. This kind of maintenance for the steel wire rope There will be a lot of maintenance costs and the use will be suspended during the maintenance period, which will affect the continuity of use

[0006] Therefore, the production enterprises and scientific research units of elevator ropes have done a lot of research and development, but they have not been able to obtain satisfactory results, and the installers and users of elevators also hope to have an electrical appliance with high strength, good lubrication and shaping, and long service life. with rope
