Carbon fiber bilayer plastic wrapped steel rope specially used for elevator

Abstract

The invention relates to a carbon fiber bilayer plastic wrapped steel rope specially used for an elevator and belongs to the technical field of elevators. The carbon fiber bilayer plastic wrapped steel rope specially used for the elevator is provided with a carbon fiber rope core, wherein a synthetic plastic inner protective layer is wrapped outside the carbon fiber rope core; a suction disc which is densely covered by ranks of micro ridges and slots is wrapped outside the inner protective layer; a braided steel wire rope is arranged outside the suction disc, and a synthetic plastic shell is extruded and wrapped outside the steel wire rope. The carbon fiber bilayer plastic wrapped steel rope disclosed by the invention has a scientific and reasonable structure; an intermediate sizing rope core adopts a carbon fiber plastic wrapped rope; a plastic wrapped surface imitates the mode of the suction disc of a wall gecko, and the suction disc which is densely covered by ranks of micro ridges and slots is arranged, so as to enhance the binding ability of the carbon fiber bilayer plastic wrapped steel rope with other materials; the shell is wrapped by the synthetic plastic; and the tensile strength of the carbon fiber resin composite material is 3500MPa or above and is 7-9 times that of a steel wire while the weight of the carbon fiber resin composite material is one fourth of the weight of the steel wire of the same class, thus the carbon fiber bilayer plastic wrapped steel rope disclosed by the invention has a prospect in application of the elevator and is a replacement product of an elevator hoisting rope.

Description

technical field [0001] The patent of the invention relates to a special carbon fiber double-layer plastic-wrapped steel rope for elevators, which belongs to the technical field of elevators. Background technique [0002] At present, the traction transmission steel ropes of elevators are all braided with steel wires. According to different use environments and functions, some steel wire ropes use hemp cores in the middle, and some steel wire ropes use steel cores in the middle. These two types both play the role of lubricating and shaping (hemp core) and increasing strength (steel core). Although the steel core can increase the strength, it has unique physical characteristics - too rigid and easy to break. Although the hemp core is well lubricated and shaped, its tensile strength is poor. Therefore, the production, installation and users of elevators all hope to have a steel wire rope for elevators with high strength, good lubrication and shaping, and long service life. Co...
