Abstract
Description
Technical Field
[0001] This utility model relates to an elastomeric drag chain cable suitable for complex paths, belonging to the field of cable technology. Background Technology
[0002] Drag chain cables: In applications where equipment units need to move back and forth, to prevent cables from becoming tangled, worn, pulled out, snagged, or scattered, cables are often placed in cable drag chains. This provides protection for the cables, and the cables can also move back and forth with the drag chain. These highly flexible, specialized cables that can move back and forth with the drag chain without easily wearing out are called drag chain cables, also commonly known as towing cables or tank chain cables. Drag chain cables cannot be twisted during installation, have long laying periods, and lack anti-bending structures at turning points in complex laying paths. Utility Model Content
[0003] The purpose of this invention is to provide an elastomer drag chain cable suitable for complex paths, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: an elastomeric drag chain cable suitable for complex paths, comprising an outer sheath, a shielding layer, an inner sheath, a cable core, a horizontal plate, positioning mounting blocks, a cable threading frame, a central support, and an anti-twist cable release rod. The sheath, shielding layer, inner sheath, and cable core are arranged concentrically from the outside to the inside. Positioning mounting blocks are welded to both sides of the upper surface of the horizontal plate, and a central support is installed at the center of the lower surface of the horizontal plate. The cable threading frame is positioned on both sides of the horizontal plate and at the center of the central support by bolts. The outer sheath is connected to the inner groove of the anti-twist cable release rod.
[0005] Preferably, the central support consists of a guide rod, a buffer spring assembly, and an arc-shaped frame, with the guide rod positioning and installing the arc-shaped frame via the buffer spring assembly.
[0006] Preferably, the anti-torsion wire feeding sleeve is composed of a sleeve, an arc-shaped pressure cap, and a front buffer guide roller. The arc-shaped pressure cap is installed at the front end of the sleeve cut, and the front buffer guide roller is welded to the front end of the sleeve.
[0007] Preferably, the threading frame has a built-in rotating shaft.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] The anti-twist cable laying sleeve consists of a sleeve, an arc-shaped pressure cap, and a front buffer guide roller. The outer sheath is connected to the inner groove of the anti-twist cable laying sleeve. The arc-shaped pressure cap limits the position of the cable during the cable laying process, and the front buffer guide roller provides guidance and support during the cable laying process, thereby releasing the elastic torque of the rubber layer of the cable's outer sheath and preventing the cable from twisting during the laying process.
[0010] At large-angle turning nodes, cables are installed sequentially through the cable tray and central support to form an arc-shaped installation, with buffer springs used to cushion the cable laying structure. Attached Figure Description
