Dragging belt of composite materials

Abstract

The invention discloses a dragging belt of composite materials. The dragging belt is light in weight and good bending performance. The dragging belt comprises a plurality of inner bearing body layers and abrasion-resisting elastic bodies wrapped outside the inner bearing body layers. The inner bearing bodies are in a sheet shape which is continuous in the single length direction of the dragging belt. Each inner bearing body comprises a base body. A plurality of nonmetal non-twist continuous fiber monofilaments are arranged in the base bodies, the nonmetal non-twist continuous fiber monofilaments are not in contact, the base bodies of inner bearing body layers are made of thermosetting resin materials or thermoplastic resin materials, the abrasion-resisting elastic bodies are thermoplastic polyurethane or rubber elastic bodies. At least two inner bearing body layers are arranged in the thickness direction of the dragging belt. The thickness of the inner bearing body layers of the sheet-shaped structure of the dragging belt is small, under the premise that good bearing is achieved, bending curvature radius is greatly lowered, the obtained dragging belt is light in weight, high in intensity and easy to bend, abrasion resistance and whether resistance are achieved, anti-fatigue performance is achieved, service life is long, maintaining cost is low, and the dragging belt can be used for lifting of long-distance heavy objects.

Description

technical field [0001] The invention relates to a traction belt of composite material. Background technique [0002] The density of traditional steel wire ropes for elevators is high. When the lifting height increases, its self-weight will lead to a serious decline in lifting capacity. Moreover, the weather resistance of steel wire ropes is not good, requiring regular inspection and maintenance, and the maintenance cost is high. Composite materials have ultra-high specific strength, fatigue resistance, and weather resistance. Excellent performance, can well achieve weight reduction to replace the traditional steel wire traction rope and traction belt. [0003] The patent document with publication number CN102002872A and invention titled "Fiber Braided Flexible Composite Traction Belt for Elevator and Manufacturing Method" discloses a composite traction belt, which is woven from steel wire or synthetic fiber. The braid has a tightly bonded plastic wrap around and inside. Al...

AI Technical Summary

Problems solved by technology

Due to the high modulus of the load-bearing phase and the limitation of large thickness, its bending property is extremely poor, so it is not suitable for use as elevator traction belt, and its fatigue performance is also under experimental verification
