Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a view suspension bridge main push-towing rope moulds wire rope with filling out package, as shown in fig. 1, including steel core strand 1, steel core strand 1 periphery is provided with the outer thigh 2 of steel core with the contact of steel core strand 1, and the outer thigh 2 outside cladding of steel core has many owner thigh 3.
A first plastic filling layer 4 is arranged between the steel core strand 1 and the steel core outer strand 2, and a second plastic filling layer 5 is arranged between the steel core outer strand 2 and the main strand 3.
The outer side of the main strand 3 is provided with a plastic coating layer 6.
The first plastic filling layer 4, the second plastic filling layer 5 and the plastic coating layer 6 are all made of modified polyethylene.
The outer thigh 2 of steel core is provided with 6 thighs, and main thigh 3 is provided with 6 thighs.
The thickness of the plastic-coated layer is not less than 6.0 mm.
The utility model relates to a view suspension bridge main push-towing rope moulds wire rope with filling out interior thigh 1 of steel core, first fill out and mould layer 4, the steel core is outer thigh 2 and the second is filled out and is moulded layer 5 and once injection moulding through the extruding machine, the package is moulded the layer and is passed through extruding machine secondary injection moulding, the whole outline of wire rope is glossy circular cross section, the steel core is constituteed to strand 1 in the steel core and the outer thigh 2 of steel core, the steel core structure shows to be 6 x 7-1 x 7, wire rope includes steel core and main thigh 3, wire rope overall structure shows to be: EP 6X 37S-EP 6X 7-EP 1X 7 or EP 6X 36WS-EP 6X 7-EP 1X 7.
Taking an EP (6 multiplied by 37S-IWRC)52.0mm suspension bridge main cable steel wire rope as an example, a main strand 3 comprises six twisted strands, the strand structure is (1-6/15-15), the steel wire rope is twisted twice by a tubular stranding machine, firstly, the (1-6) structural strand twisting is carried out, and then, the (15-15) structure is twisted once on the periphery of the (1-6) strand. The steel wire rope is twisted by a basket type rope combining machine, and the twisting pitch multiple of the steel wire rope is not less than 8.0. After the steel wire rope is twisted, pre-tensioning treatment is carried out on pre-tensioning equipment, and the actually measured elasticity of the pre-tensioned steel wire rope is not less than 110 GPa. And (2) performing injection molding on a plastic-coated line after pre-tensioning treatment, wherein the injection molding is performed twice by using the special modified polyethylene for the bridge cable, the plastic is extruded out of the space between each strand of the steel wire rope after the first injection molding and slightly extends to the outer surface of the steel wire rope to form a plastic filling layer 4, and the plastic filling layer 4 forms a net-shaped integral structure in the steel wire rope. After the secondary injection molding, the polymer is uniformly coated on the outer surface of the primary injection molding steel wire rope to form a plastic coating layer 5, the thickness of the plastic coating layer reaches more than 6.0mm, and the polymer subjected to the primary injection molding and the secondary injection molding is ensured to be tightly combined through the preheating of the steel wire rope and the heating temperature control of the polymer.
The utility model discloses wire rope lay length multiple is not less than 8.0, and wire rope is handled through the stretch-draw technology in advance, and actual elastic modulus can reach more than 110GPa, and the extension of wire rope structure is little, has guaranteed the structural stability of suspension bridge, fills out to mould the layer and the special modified polyethylene of bridge cable is adopted to the layer polymer is moulded to the package, has guaranteed that the layer polymer is moulded to the package has good anticorrosive, ageing resistance, through twice injection moulding, fills out to mould the layer and the layer combination is inseparable is moulded to the package.
The utility model discloses a fill out and mould layer and can alleviate wearing and tearing, the extrusion between strand and the thigh, guaranteed that wire rope has good fatigue resistance ability and shock resistance, the package is moulded the layer and is kept apart wire rope and external environment, can seal and protect the inside grease of wire rope, prevents the grease polluted environment to prevent that wire rope from receiving external environment pollution or corruption, improve main push-towing rope anticorrosion, antifouling characteristic, and the coating colour is bright-colored, has strengthened the sight of view suspension bridge.
