Technical Field
[0001] The utility model relates to the technical field of ladle car cables, in particular to a high temperature resistant, tensile resistant and drag resistant ladle car cable. Background Art
[0002] As the name suggests, a ladle car is an electric flat car with a freely controllable running speed for transporting ladles. It is often used in the metallurgical manufacturing industry to solve problems that cannot be solved by manpower, such as the transportation of high-temperature molten steel and slag, thereby improving the overall processing efficiency and safety.
[0003] However, the reciprocating stretching and high temperature environment during the operation of the ladle car also pose a great challenge to the supporting cables. Therefore, scientific researchers in related fields are also constantly improving the cables of the ladle car. For example, the authorized patent with announcement number CN216697887U and the subject name of a tensile and wear-resistant cable for a ladle car states that "the utility model adopts a multi-layer protective design to effectively protect the internal wires. The cable is equipped with mounting parts on the outside, which can be used for cables of different diameters and can also be fixed on the ladle car to effectively avoid damage caused by dragging the cable on the high-temperature ground."
[0004] From the above disclosed technical contents, the additional auxiliary structure for the ladle car cable in the above prior art only improves the compressive and tensile strength of the connection between the ladle car cable and the ladle car, and the scope of use is limited. Secondly, the cable in the above prior art still adopts hard collision tensile resistance for the stretching caused by the reciprocating movement of the ladle car, which has poor protection effect on the internal components of the cable. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a high temperature resistant, tensile resistant and drag resistant ladle car cable, which solves the problems raised by the above background technology.

[0007] An elastic folding sleeve is arranged between one ends of the two outer protection kits, and the elastic folding sleeve covers and protects the structure of the linkage bar located between the two outer protection kits.
[0008] Preferably, the linkage bar is located between one ends of the two outer protection kits and is a folded structure, and the linkage bar is mainly composed of spring steel wire.
[0009] Preferably, the surfaces of one ends of the two outer protection kits are provided with external threads, and the inner sides of the two ends of the elastic folding sleeve are respectively threadedly connected with the surfaces of one ends of the two outer protection kits.
[0010] Preferably, the two outer protection kits each include a first combined arc plate and a second combined arc plate, the first combined arc plate is assembled and connected to the second combined arc plate, and the inner wall of the first combined arc plate and the inner wall of the second combined arc plate are both fitted and connected to the surface of the high temperature resistant cable body.
[0011] Preferably, the first combined arc plate and the second combined arc plate are assembled symmetrically to each other, and an assembly gap between the first combined arc plate and the second combined arc plate is filled and sealed by strong glue.
[0012] Preferably, an elastic hook plate is fixedly connected to the planar end face of the first combined arc plate, and a clearance groove which is clamped with the elastic hook plate is opened on the planar end face of the second combined arc plate. The first combined arc plate and the second combined arc plate are assembled and coated on the surface of the high temperature resistant cable body by clamping the elastic hook plate with the clearance groove.

[0016] 1. The utility model forms a protective ring structure on the surface of the high temperature resistant cable body by means of the linkage strip, the outer protective kit and the damping ring. When used together with the high temperature resistant cable body and the ladle car, the protective ring structure not only shares the dragging force suffered by the high temperature resistant cable body with its own structure and improves the wear resistance, but the outer protective kit inside the protective ring structure will also move under pressure, and then shrink the open structure in the linkage strip and collide with the damping ring structure to achieve multiple buffers, and finally avoid the high temperature resistant cable body from being tensilely resisted by hard collision, thereby fully protecting the internal components of the high temperature resistant cable body.
[0017] 2. The internal and external protection kits of the environmental protection structure proposed by the utility model are composed of assembled structures, which not only ensures its own strength of use, but also creates favorable conditions for subsequent material recovery, replacement and maintenance of some areas, etc. BRIEF DESCRIPTION OF THE DRAWINGS
