Dragging and dropping flexible cable used for harbor machinery

Abstract

The invention discloses a dragging and dropping flexible cable used for harbor machinery. The dragging and dropping flexible cable comprises a dragging and dropping flexible cable body, a wind power detection sensor and a rope coiling box, wherein an anticorrosive coating is arranged inside the dragging and dropping flexible cable body; a fire-retardant coating is arranged inside the anticorrosivecoating; an outer sheath is arranged on the side, away from the anticorrosive coating, of the fire-retardant coating; a flax yarn braid layer is arranged on the side, away from the fire-retardant coating, of the outer sheath; an inner sheath is arranged on the side, away form the outer sheath, of the flax yarn braid layer; and a strengthened filling core is arranged on the side, away from the flax yarn braid layer, of the inner sheath. According to the dragging and dropping flexible cable used for harbor machinery, flax yarns are sparsely braided outside the inner sheath, and then the outer sheath is extruded, so that the outer sheath, the flax yarn braid layer and the inner sheath are fused integrally, and the tensile capacity of the cable is greatly enhanced; moreover, the fire-retardant coating and the anticorrosive coating are additionally arranged outside the outer sheath, so that the applicable capacity of the dragging and dropping flexible cable on harbor environment is strengthened, and the dragging and dropping flexible cable is simple in structure, reasonable in design and high in applicability.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a dragging flexible cable for port machinery. Background technique [0002] In recent years, with the rapid development of the national economy, China is ushering in the golden age of port development. Following the addition of two 100 million-ton ports in Nanjing and Suzhou in 2005, China added two 100 million-ton ports in 2006. As of the end of 2006, the number of ports with 100,000,000 tons in mainland China has increased to 12. At present, the world economic structure and industrial layout are in a period of adjustment. Transportation has directly promoted the rapid growth of the port's foreign trade throughput; according to the "Eleventh Five-Year Development Plan for Highway and Waterway Transportation" issued by the Ministry of Communications, by 2010, coastal ports will increase their throughput capacity by 2.1 billion tons, which is the number passed during th...

Problems solved by technology

[0003] There are the following problems in the port machinery dragging flexible cables in the prior art: 1. Due to the frequent hoisting of port machinery, the supporting cables often need to move at high speed, bear large pulling force and bending, and the cables are exposed to the port environment for a long time, withstand With the impact of the strongly changing port climate, the traditional towed flexible cables usually have various broken failures after about half a year of use, which affects the use and increases the cost of port machinery; 2. The wind in the port area is strong, and once the towed flexible cable Blown by strong winds, it is easy to shake from side to side and collide with adjacent port machinery to damage its internal structure, shortening the service life of the towing flexible cable, and it is easy to entangle among multiple towing flexible cables, and even cause some other serious accidents
