Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high-flexibility, torsion-resistant and tension-resistant cable. Background Art

[0002] Tensile cable is a specially designed cable designed to withstand high mechanical stress, drag, twisting, and high abrasion and torsion resistance. This cable is typically used in applications where the cable is subject to reciprocating motion and mechanical stress, such as cable tracks, transport lines, handling machines, cranes, elevators, and more. It can be used indoors or outdoors in dry or humid environments. Its special design allows it to remain stable under frequent movement and operation, effectively preventing cable rotation and deformation, thereby ensuring the normal operation of equipment and improving work efficiency. Furthermore, tensile cable is also suitable for applications with high mechanical stress resistance, particularly those subject to both tensile and torsional stresses, such as shipyards, ports, warehouses, steel logistics, and loading and unloading machines, drilling rigs, and coal mining machines.

[0003] However, during the use of existing cables, since the outer insulating sheath is sheathed outside the cable core, the insulating sheath and the cable core are in a certain degree of mobility, and the friction resistance generated between them improves the tightness of the connection between the two, so that when subjected to torsional force, there will be separation between the two, resulting in poor torsion resistance and subsequent tensile strength, thereby reducing the utilization rate. Utility Model Content

[0004] The purpose of the utility model is to provide a highly flexible, torsion-resistant and tensile-resistant cable in order to solve the problem that when subjected to torsional force, separation occurs between the insulating sheath and the cable core, resulting in poor torsion resistance and subsequent tensile resistance, thereby reducing its utilization rate.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a highly flexible, torsion-resistant and tensile-resistant cable, comprising:

[0006] Cables are used for power connections in various equipment, devices and instruments that require DC high-voltage power cables;

[0007] A reinforcement component is located outside the connection end and is connected to the cable by clipping;

[0008] The cable includes an insulating sheath, a filling layer is arranged inside the insulating sheath, and multiple groups of cable cores are evenly arranged inside the filling layer. The reinforcement component includes a reinforcement ring, and both ends of the reinforcement ring are provided with ends to be extruded. Both ends of the reinforcement ring and the end close to the end to be extruded are evenly provided with multiple groups of pressing teeth.

[0009] As a further solution of the present invention, the pressing teeth are all inclined upward, and the pressing teeth are in pressing contact with and clamped to the two ends of the exterior of the insulating sleeve.

[0010] As a further solution of the present invention: multiple groups of friction lines are evenly arranged on the outside of the end to be extruded.

[0011] As a further solution of the present invention: a plurality of connection ends are evenly arranged on the outer side of the cable.

[0012] As a further solution of the present invention: connecting seams are provided at the top and bottom of both ends of the reinforcement ring, and the end to be extruded is bent and connected to the reinforcement ring through the connecting seams.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting up the cable and reinforcement assembly, when in use, the reinforcement ring is put on the outside of the cable, and a group of reinforcement rings are set at a certain distance, and then the end to be squeezed is squeezed with the help of external pliers. The end to be squeezed is deformed by force, and the reinforcement ring is slightly carried counterclockwise during the squeezing process, so that the pressure teeth inside the reinforcement ring are better clamped on the outside of the insulating sheath (conversely, the reverse clockwise operation can be used to remove the reinforcement ring from the outside of the cable, which is convenient for operation and reduces the difficulty of operation), and the original arc shape is changed into a straight plate, and the pressure teeth inside the reinforcement ring are tightly clamped on the outside of the cable, and the pressure teeth squeeze the insulating sheath, so that the insulation sheath at the force position and the cable core fit more tightly, so that the firmness between the insulation sheath and the cable core is stronger, so that it is tighter when subjected to torsional force, so that its torsion resistance and subsequent tensile strength are better, thereby improving the utilization rate.
