Problems solved by technology
[0006] The purpose of the present invention is to provide a compression-resistant underground cable and its laying device, to solve the existing underground cables on the market proposed by the above background technology. Due to the particularity of the underground cable laying environment, other common cables are relatively ratio, it needs to have a certain compression resistance, so as to avoid the underground cable being squeezed by external force and damaged after laying, and after laying the underground cable, due to the limited length of the cable, after the underground cable is connected, it is necessary to pay attention to the alignment of the cable The contact is protected to prevent external force from damaging the joint of the cable, as well as the impact of stretching on the joint of the underground cable

The invention discloses a compression-resistant underground cable and a laying device thereof. The cable comprises an underground cable body, a cable core, an insulating layer, a filling layer, a metal armor layer, the laying device and a rotating shaft, wherein the cable core is arranged in the center of the underground cable body, and the insulating layer made of a rubber material is arranged onthe outer side of the cable core; the outer side of the insulating layer is wrapped with a metal armor layer, guide grooves are formed in the front side and the rear side of the upper end face of thefixing base, guide blocks are slidably connected into the guide grooves, and the upper portions of the guide blocks are in threaded connection with screwing screws. According to the compression-resistant underground cable and the laying device thereof, through improvement of an existing cable structure, the compression-resistant effect of the cable can be improved, the situation that the underground cable is damaged due to extrusion of an external force after being laid is avoided, and through the corresponding laying structure, the connecting position of the underground cable can be furtherprotected, so the connecting part of the underground cable is prevented from being damaged by external force and stretching.
Description
technical field [0001] The invention relates to the technical field of underground cables, in particular to a compression-resistant underground cable and a laying device thereof. Background technique [0002] Cable is a commonly used power connection component in electrical equipment. It is usually made of several or several groups of wires. According to different installation environments, it can be divided into underground cables, outdoor cables and indoor cables. They are composed of single-strand or multi-strand wires and insulation layers, and are mainly used to connect circuits, electrical appliances, etc. When laying underground cables, it is generally enough to lay the underground cables in the pre-dug laying pit through the installation frame. Since the length of each roll of cable is limited, it is necessary to dock multiple rolls of underground cables. After the docking is completed, it is necessary to Protect the butt joints of underground cables to avoid damage...
