Description

Technical Field

[0001] This utility model relates to the field of drag chain cables, and in particular to a naturally cross-linked energy-saving drag chain cable. Background Technology

[0002] Drag chain cables are common structures used for electrical conduction and communication in the field of mechanical engineering. They generally include a drag chain assembly and multiple cable bodies installed in the drag chain assembly. The cable bodies can move back and forth with the drag chain assembly, making them suitable for applications where equipment needs to move back and forth. The cable bodies are located inside the drag chain assembly, which can prevent the cable bodies from getting tangled or worn.

[0003] Chinese Patent CN218678392U discloses a conveniently installed drag chain cable, including drag chain blocks and drag chain cables. Key technical features include a lower support plate fixed between two drag chain blocks, an upper support plate symmetrically hinged between the two blocks, symmetrical insertion slots and locking slots on opposite sides of the two upper support plates, an insertion plate spring fixedly installed at the bottom of the insertion plate slot, an insertion plate spring tube fixedly connected to the insertion plate, a pull plate slot extending through the side wall of the upper support plate, and a pull plate fixedly connected to the side wall of the insertion plate within the pull plate slot. Adjacent drag chain blocks intersect to form a drag chain. When installing the drag chain cable, simply open the upper support plate and place the drag chain cable into the cable installation slot. A limiting block restricts the drag chain cable, making installation convenient.

[0004] The existing technical solutions described above have the following drawbacks: the drag chain cable is secured in the cable installation groove by two adjacent sets of limiting blocks. Since the drag chain blocks can bend with the drag chain cable, problems arise when the cable is installed and bent under force. Additionally, the outer side of the limiting blocks is relatively sharp, making it easy for the drag chain cable to overcome the elastic force of the limiting spring and slide out of the cable installation groove. This results in unreliable fixing of the drag chain sprocket or the limiting blocks being squeezed outwards when removed. The sharp part of the limiting blocks can easily damage the drag chain cable. To address these issues, a natural cross-linking energy-saving drag chain cable is proposed. Utility Model Content

[0005] Based on this, it is necessary to address the technical problem that drag chain cables easily overcome the elastic force of the limiting spring when bent under stress, thus slipping out of the cable installation groove, resulting in unreliable fixation of the drag chain sprocket. The proposed solution is a naturally cross-linked energy-saving drag chain cable, comprising: a chain block and a conductor body. The conductor body includes a wear-resistant layer, a sheath, a wrapping layer, a braided layer, an oxygen barrier layer, fishing line, a filler layer, a metal core, and an insulation layer. The wear-resistant layer has a sheath on its inner wall, the sheath has a wrapping layer on its inner wall, the wrapping layer has a braided layer on its inner wall, the braided layer has an oxygen barrier layer on its inner wall, the oxygen barrier layer contains a filler layer, the filler layer contains fishing line, and several insulation layers are arranged around the fishing line within the filler layer. Each insulation layer contains a metal core. The chain block includes a top cover, two symmetrical guide grooves on its upper surface, limit grooves on opposite surfaces of its inner wall, and several bases within the chain block.

[0006] The bottom surface of the upper cover is provided with several pressure seats, and the pressure seats are provided with anti-slip pads II and the base is provided with anti-slip pads I.

[0007] The upper cover has movable grooves on both opposite surfaces. A spring is provided on one side of the inner wall of the movable groove. A guide groove is provided on both opposite surfaces of the inner wall of the movable groove. A sliding groove is provided on the upper surface of the inner wall of the movable groove. A pull plate is provided in the sliding groove. A slider is slidably connected in the guide groove. A limit block is provided on the left side of the pull plate and a pull plate is provided on the right side of the pull plate.

[0008] In one embodiment, the free end of the spring is fixedly connected to the left side of the pull plate, the opening on one side of the movable groove communicates with the limiting groove, the shape and size of the limiting block are adapted to the limiting groove, the guide groove is connected to the limiting groove, and the shape and size of the guide groove are adapted to the limiting block.

[0009] In one embodiment, the insulating layer is a polyester elastomer, the abrasion-resistant layer is an EVA abrasion-resistant material, the sheath is a polyester elastomer, the wrapping layer is foamed polyethylene, the braided layer is provided with a woven metal mesh, the oxygen barrier layer is a highly flame-retardant elastomer, and the filling layer is a PP tear-resistant mesh.

[0010] It should be noted that, during operation, the centrally positioned fishing line of the aforementioned naturally cross-linked energy-saving drag chain cable effectively improves the swaying performance of the drag chain cable, thereby extending its service life. Furthermore, the wrapping layer, made of foamed polyethylene, possesses excellent impedance and good impedance stability, enhancing the impedance stability of the drag chain cable. Simultaneously, the filler layer, made of PP tear-resistant mesh, features low density, good filling effect, reduced cable weight, and convenient construction and maintenance, while also improving the cable's resistance to torsion and tensile strength. The oxygen barrier layer, made of highly flame-retardant elastomer, isolates external oxygen from the core, significantly improving the cable's flame-retardant performance. The sheath, made of polyester elastomer, offers superior temperature resistance, chemical resistance, and stress crack resistance compared to traditional cables, effectively improving the cable's resistance to torsion and tensile strength. The wear-resistant layer, made of EVA, is melt-extruded onto the sheath, tightly wrapping it and protecting the drag chain cable body, effectively improving the cable's outer sheath wear resistance, preventing wear and damage due to long-term use, preventing outer sheath cracking, and extending service life.

[0011] When the conductor body needs to be replaced or repaired, pull the second pull plate on the surface of the top cover to move it to the middle. The second pull plate pulls the first pull plate to move together. The first pull plate drives the limiting block to disengage from the limiting groove and retract into the movable groove, so that the top cover can be removed. During installation, align the limiting block with the guide groove and press the top cover together. When the movable groove and the limiting groove are aligned, the limiting block will spring back into the limiting groove to complete the limiting. Attached Figure Description
