TECHNICAL FIELD

[0001] The present application relates to the technical field of cable, in particular to a shearing-resistant protective cross-linked polyethylene aluminum alloy cable. BACKGROUND

[0002] The shearing-resistant protection of aluminum alloy cable is a crucial problem in industry. Part of the cable will move with the equipment during the operation of the equipment. When the equipment moves, the cable will be squeezed, and the cable will be subjected to shearing force, which may cause the insulation layer to be damaged, the internal conductor to be broken, and a short circuit to occur. In severe cases, it may cause equipment failure and shutdown. In terms of shearing-resistant protection of the cable, the cable is given priority to be avoided, but the cable still needs to be protected in positions where the cable may be squeezed and bumped.

[0003] Traditional shearing-resistant protection of the cable is to set a physical protection on the outside of the cable, which is the most intuitive protection method. Currently, corrugated pipes, spiral pipes or woven mesh pipes are commonly used, which are wrapped on the cable. The flexibility of the cable can be ensured, and the impact resistance and shearing resistance of the cable can be improved. However, in order to wrap the cable with the pipe body, the diameter of the pipe body should not be larger than the cable. Sometimes, the pipe body cannot pass through the plug on the cable, which makes it difficult to wrap the pipe body on the cable. In addition, when the cable is connected to the equipment at both ends, it is difficult to wrap the pipe body on the cable at one end of the cable. SUMMARY

[0004] The present application provides a shearing-resistant protective cross-linked polyethylene aluminum alloy cable to solve the problem that it is difficult to wrap the protective pipe body on the cable when the cable is connected to the equipment at both ends.

[0007] The sliding ring group is detachably combined by a plurality of sliding rings arranged in an arc shape, and the sliding rings are in sliding connection with the sliding grooves when the sliding ring group is sleeved on the clamping assembly.

[0008] A plurality of rotating shafts are connected to the sliding rings, and the two ends of the spiral sheath assembly are rotatably connected to the rotating shafts on the two sliding rings.

[0009] The spiral sheath assembly comprises a fixed plate, a rubber layer and a metal corrugated sheet, the two fixed plates are detachably rotatably connected to the rotating shafts, the rubber layer is fixedly connected to the fixed plate, both ends of the rubber layer are fixedly connected to the fixed plate, the metal corrugated sheet is fixedly connected to the rubber layer, and both ends of the metal corrugated sheet are fixedly connected to the two fixed plates.

[0013] When the cable body is bent, the spiral sheath assembly can drive the sliding ring group to slide on the clamping assembly, and the lap joint groove and the lap joint pressing plate slide relative to each other.

The clamping assembly and the sliding ring group are detachably assembled. When the cable is fixed on the equipment at both ends, the clamping assembly and the sliding ring group can also be fixed. It is not necessary to disconnect the cable and then sleeve it. The spiral sheath assembly is spirally wound on the cable body 1. Through the number of spiral windings and the distance, one spiral sheath assembly can protect cables of various lengths. Since the plurality of spiral sheath assemblies are spirally twisted and sleeved on the cable body 1, the overlapped spiral sheath assemblies can bend by sliding when the cable body 1 is bent. When the cable sheath assembly is damaged due to extrusion, it is convenient to replace and maintain.

[0020] As shown, Figs. 1-4 The clamping assembly comprises a plurality of clamping rings 2, which are arranged in a circular arc shape and can be detachably assembled into a circular shape.
