Abstract
A high strength large size steel wire rope sling, which is twisted by a metal rope core and eight outer strands in one time, wherein, the metal rope core is formed by a metal strand core, six outer big strands and six outer filling small strands, the rope core employs injection molding. The steel wire rope sling has merits of big bearing capability, high anti-fatigue performance, corrosion resistance, flexible capability and long service life, using the steel wire rope sling on the suspension bridge can reduce the bearing load on the top structure of the bridge, enhance the service life of the bridge, reduce build cost of bridge and enhance product efficiency.
Description
One, technical field
The utility model relates to a kind of high strength and large specification wire rope sling, belongs to the metallic article technical field.
Two, background technology
Existing wire rope sling, structure is 6 * 37 classes, wire rope core be six strands metal-cored, the steel wire rope internal structure is not tight, metal filled coefficient is little, the wire rope sling bearing capacity is low, corrosion-resistant and fatigue performance is poor, large-span suspension bridge uses this structure wire rope sling, for reaching load bearing requirements, correspondingly will increase wire rope sling intensity level and diameter, reduced the fatigue performance of wire rope sling, increased the weight loading of suspension bridge superstructure, increased cost simultaneously, 6 * 37 class wire rope slings have been not suitable for the large-span suspension bridge instructions for use.
Yet there are no the wire rope sling that is better than 6 * 37 class formations in the market.
Three, summary of the invention
The purpose of this utility model is in order to overcome deficiency of the prior art, provide a kind of metal filled coefficient and the rupture pull force coefficient is big, bearing capacity is big, corrosion-resistant, flexility and anti-fatigue performance height, improve service life simultaneously, reduce production costs the high strength and large specification wire rope sling of enhancing productivity.
The technical scheme that the utility model adopted is:
The wire rope sling structure is 8 * 37 classes, steel wire rope is formed by a metal core (IWR) and eight outer layer strand primary twistings, metal core is by a metal thigh core, the metal-cored outer shallow bid primary twisting of filling of big strand of the metal-cored skin of the six roots of sensation and the six roots of sensation forms, metal thigh core, big strand of metal-cored skin and outer layer strand are formed by 19-55 root steel wire twisting, and the outer shallow bid of filling is formed by 7-31 root steel wire twisting.Metal core adopts injection mo(u)lding, also can not injection moulding.
But the steel wire rope of steel wire radical or diameter twisting different-diameter in the change steel wire rope, the steel wire rope lay pitch is 7.0～8.5 times of its nominal diameter.
Adopt the beneficial effect of such scheme to be:
1, the metal core outer surface is full in the wire rope sling, and structure is tight, and metal filled coefficient, rupture pull force coefficient and bearing capacity are big;
2, wire rope sling anti-fatigue performance height, flexility is good;
3, the wire rope sling corrosion resistance is good, high life;
4, reduce the bridge construction cost, enhance productivity.
Four, description of drawings
Accompanying drawing 1 is a high strength and large specification wire rope sling cross section structure schematic diagram.
Among Fig. 1: 1-metal thigh core, big strand of the metal-cored skin of 2-, metal-cored outer shallow bid, the 4-outer layer strand of filling of 3-.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated: accompanying drawing 1 is a kind of high strength and large specification wire rope sling specific embodiment of the utility model, it is formed by a metal core and eight outer layer strand primary twistings, wherein metal core is again by a metal thigh core 1, six roots of sensation isostructure, with the outer big thigh 2 of diameter metal core, six roots of sensation isostructure, form with the outer shallow bid 3 of filling of diameter metal core, typical structure is 6 * 16W+6 * 36WS+1 * 55SWS (41WS), metal thigh core 1 in above-mentioned each strand, outer big strand 2 of the six roots of sensation, eight steel wire rope outer layer strand 4 are formed by 19-55 root steel wire twisting, and the outer shallow bid of filling is formed by 7-31 root steel wire twisting.Steel wire rope outer layer strand typical structure is 36WS, 41WS, 49SWS, 55SWS etc.But during processing and fabricating by change wherein the steel wire radical or the wire rope sling of diameter twisting different-diameter, the wire rope sling lay pitch is 7.0～8.5 times of its nominal diameter.The typical structure of this wire rope sling is 8 * 55SWS (or 41WS)+IWR.
Claims (6)
