A special cable for slag tanker

Abstract

The invention discloses a special cable for slag tank trucks, which includes several insulating electric cores arranged in parallel, the insulating electric cores include several conductors, each conductor is extruded and provided with a rubber insulating layer, and the outer covering of the insulating electric cores is provided with a protective The protective cover is provided with a via hole for accommodating the insulated electric core, and an isolation part is provided between two adjacent via holes, and an I-shaped elastic part is arranged in the isolation part, and the I-shaped elastic part is evenly distributed in the length direction of the protective cover; The protective cover is also provided with a bending-resistant skeleton, which is made of metal with elasticity, and the bending-resistant skeleton is located on one side of the plane formed by several insulating electric cores. The C-shaped bone piece supporting the protective cover has a hole passing through the center of the C-shaped bone piece, and the C-shaped bone piece is evenly distributed in the length direction of the protective cover. Through the above arrangement, it can withstand frequent movement and bending and pulling, and can be used normally in a high temperature environment.

Description

technical field [0001] The invention relates to the field of dust monitoring, in particular to a special cable for slag tank trucks. Background technique [0002] Tanker, also known as slag tanker or slag packer, is a special transport vehicle for metallurgical slag treatment, with a load capacity of 25 tons to 120 tons. It is mainly used to handle slag, molten steel or other solid objects with a high temperature of about 1300 degrees. Its load capacity, length and width can be determined according to the size, volume and on-site operating environment of the user's slag tank. [0003] The slag tanker cable is used in the iron and steel smelting industry for the electrical connection between the slag tanker and the electrical cabinet. Since the slag tanker is often in a state of frequent movement and bending and dragging, the cable has a short service life and frequent replacement, which not only increases the economic cost, but also once In the event of an economic accident...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the long-term frequent bending and movement of the slag tank truck cable in a high-temperature environment, the cable sheath layer is easy to cause damage, and the damage to the insulation causes breakdown, which greatly shortens the service life of the cable; 2. The conductor of the cable has been stretched for a long time and bending, it is easy to break and deform and cause insulation "bulge"; 3. After the cable is subjected to strong impacts such as tension, pressure, bending, and friction during operation, the mechanical properties of the cable will decline; 4. After long-term bending of the cable, the cable core It is easy to slide and dislocate, and the cable core is not easy to restore the original position, causing permanent deformation of the cable insulation, and this deformation will immediately lead to the breakage of the core wire

[0005] Since the above defects cannot meet the requirements of the current steel mills, it is urgent to seek a special cable for slag tank trucks to meet the needs of the development of my country's iron and steel smelting industry
