Description

Technical Field

[0001] The utility model relates to the technical field of special cables for drag chains, in particular to a high-flexibility robot bending-resistant drag chain line. Background Art

[0002] Drag chain, also known as wire and cable protection drag chain, is a device that binds cables or wires or air pressure pipes and oil pressure pipes to facilitate their rotation and movement. Drag chain cable is a special cable installed in the drag chain. The drag chain line can effectively protect the cable from damage by external objects, cutting, twisting, wear and other factors. It can withstand mechanical movement, vibration and environmental pressure, ensuring the stability and reliability of cables and conduits.

[0003] Existing drag chain cables are often used in industrial robots. Industrial robots often drive cables to bend and move multiple times. Therefore, it is necessary to ensure that the cables have a certain bending resistance to prevent the cables from being damaged due to excessive bending. At the same time, industrial robots may be used in some harsh environments, so the inside of the cable needs to be protected. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art that cables are easily damaged due to excessive bending times and need to be protected when used in harsh environments, and proposes a highly flexible robot bending-resistant drag chain line.

[0005] In order to achieve the above-mentioned objectives, the utility model adopts the following technical scheme: a highly flexible robot bending-resistant drag chain line, comprising a drag chain cable main body, a group of wire cores are arranged inside the drag chain cable main body, the outer walls of one group of the wire cores are all provided with an insulating layer, the outer walls of one group of the insulating layers are provided with a shielding layer, the outer walls of one group of the shielding layers are provided with a filling layer, non-woven cotton cloth is arranged inside the filling layer, tensile-resistant cotton rope is arranged inside the filling layer, the outer wall of the filling layer is provided with a flame retardant layer, the outer wall of the flame retardant layer is provided with a waterproof layer, and the outer wall of the waterproof layer is provided with an outer sheath.

[0006] Preferably, the outer surface wall of the outer sheath is provided with a wear-resistant layer.

[0007] Preferably, the thickness of the insulating layer is 0.5 mm to 0.6 mm, and the thickness of the shielding layer 3 is 0.5 mm to 0.6 mm.

[0008] Preferably, the flame retardant layer has a thickness of 4 mm to 6 mm.

[0009] Preferably, the waterproof layer has a thickness of 2 mm to 3 mm.

[0010] Preferably, the outer sheath has a thickness of 4 mm to 6 mm.

[0011] Preferably, the wear-resistant layer has a thickness of 3 mm to 4 mm.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, a group of wire cores are arranged inside the main body of the drag chain cable, and a group of wire cores make the transmission stable. At the same time, a filling layer is arranged on the outer wall of a group of wire cores, and non-woven cotton cloth and tensile cotton rope are arranged in the filling layer. The non-woven cotton cloth can play a role of buffering and protection, and can prevent the cable from being damaged by mechanical extrusion or impact of external objects. It can absorb impact force and reduce the pressure and distortion of the cable. The tensile cotton rope plays a role in enhancing strength and stability in the cable. It can increase the tensile resistance of the cable and prevent the cable from being broken or deformed by large tension. The tensile cotton rope also helps to provide additional support and operating space during the installation and maintenance of the cable. The non-woven cotton cloth and the tensile cotton rope can provide better wear resistance for the cable. They can reduce the friction and wear between the cable and other surfaces, and prevent the cable outer skin from being worn or damaged. The cooperation between the two improves the tensile resistance and bending resistance of the cable and extends the service life of the cable.

[0014] 2. In the utility model, a flame retardant layer is arranged inside the main body of the drag chain cable. When the cable catches fire, the flame retardant layer can prevent the fire from expanding and slow down the spread of the flame, thereby protecting the cable from being damaged by the fire. At the same time, an outer sheath and a wear-resistant layer are arranged. The outer sheath can ensure that the cable is not corroded or damaged by the external environment, chemicals, ultraviolet rays, etc., and can also make the cable have a certain resistance to high and low temperatures. The wear-resistant layer is located on the outside of the cable, and is mainly used to increase the wear resistance of the cable, which can prevent the cable surface from being worn or scratched.

The thickness of the waterproof layer 8 is 2mm to 3mm. The thickness of the outer sheath 9 is 4mm to 6mm. The thickness of the wear-resistant layer 10 is 3mm to 4mm.

[0024] The effect achieved by the entire embodiment 2 is that the material of the insulating layer 2 is polyvinyl chloride material, which has good electrical resistance and insulation performance. The shielding layer 3 is composed of a thin layer of aluminum foil material, which can effectively shield most high-frequency electromagnetic radiation and external electromagnetic interference.
