Abstract

The invention discloses a special wear-resistant tensile cable for pile foundation equipment, and a preparation process thereof. The cable comprises a power cable core, a control cable core and a protective layer, the power cable core and the control cable core are wrapped in a cabling structure layer, and the protective layer is wrapped outside the cabling structure layer. Reinforcing elements are arranged in the middle of the power cable core and in the cabling structure layer, meanwhile, and the protective layer is made of a high-performance elastomer material and is provided with a reinforcing structure, so the wear-resisting and dragging-resisting performance of the cable is improved; and through close fit of all the layers, the problems that due to uneven stress of the mining cable, friction force among all layers of materials is different, and consequently a cable core is twisted off and a protective layer is broken are solved, the service life of the mining cable is prolonged, and meanwhile the preparation technology is simple, easy to operate and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a special wear-resistant tensile cable for pile foundation equipment and a preparation process thereof. Background technique [0002] Special cables for pile foundation equipment are mainly used for cables for mechanical equipment such as mine excavation equipment, drilling, and shield machines. It is a cable type with high performance requirements, technical difficulties, and harsh operating environments among cables for pile foundation equipment in the mining industry. One, this kind of drag cable is called "worship line" in the industry, which means that the service life is about seven days a week. Why is the service life so short? The main reason is that during the high-speed, violent, and high-frequency reciprocating dragging of the cable in a harsh environment, the cable is easily subjected to lateral or longitudinal tension, causing the control wire core ...
