Description

Technical Field

[0001] The utility model relates to the technical field of drag chain cables, in particular to an anti-breakage reinforced drag chain cable. Background Art

[0002] In occasions where equipment units need to move back and forth, in order to prevent cable entanglement, abrasion, pulling off, hanging and scattering, the cable is often placed in a cable drag chain to protect the cable, and the cable can also move back and forth with the drag chain. A drag chain cable is a highly flexible special cable that can move back and forth with the drag chain without being easily worn. Generally, the drag chain cable relies on an external drag chain for protection, but the wear resistance and tensile resistance of the internal cable are difficult to guarantee.

[0003] Chinese Patent CN216597021U discloses a wear-resistant and flame-retardant composite drag chain cable, which includes an outer rubber sleeve for protecting the whole cable. An inner rubber sleeve is arranged inside the outer rubber sleeve, and copper inner cores for power transmission are evenly arranged inside the inner rubber sleeve. A wear-resistant layer is evenly arranged on the outer surface of the outer rubber sleeve, a crack-proof layer is fixedly arranged on the inner side surface of the outer rubber sleeve, and a flame-retardant layer is arranged inside the crack-proof layer. The wear-resistant and flame-retardant composite drag chain cable adopts a new structural design, so that the device uses the outermost protruding strips to avoid direct contact between adjacent two cables during operation, thereby reducing the friction during work. And the grid-shaped crack-proof layer on the inner side can improve the overall ductility, thereby preventing breakage during use. At the same time, the internal flame-retardant layer can block the spread of fire when there is an open fire, and its elasticity and the support of the support rod can protect the inner core when being squeezed, but its tensile resistance is still limited, and the inside is too empty and is easily damaged when being squeezed.
