A kind of high-lift lifting is with compacting thigh steel cable crimping rigging, and its structure comprises steel rope, crimping noose, and said crimping noose uses steel bushing not have polar ring, and rigging adopts compaction-strand steel wire rope with steel rope.Said steel rope comprises central strand, internal layer thigh, inferior outer layer strand and outer layer strand, and steel wire is face contact shape in each strand.
Further be improved to, said steel bushing uses the 1Cr17Ni steel, and said rigging adopts the 1*7-6*7-6*7/6*7-16*7 structure with steel rope.
Moreover said compaction-strand steel wire rope intensity of steel wire is selected 1960MPA, rupture pull force coefficient 0.41.
Moreover the internal layer thigh of said steel rope wraps the sth. made by twisting central strand symmetrically.Said time outer layer strand comprises thicker inferior outer layer strand and thin time outer layer strand, and they alternately wrap symmetrically and twist with the fingers at the internal layer thigh lateral.Said outer layer strand is wrapped sth. made by twisting symmetrically in the steel rope outermost.
Moreover; The core wire cross section of said central strand, internal layer thigh, inferior outer layer strand and outer layer strand is approximate regular hexagon shape; Said outer field 6 section of steel wire are the approximate trapezoid shape and connect into ring through trapezoidal side edges; The trapezoidal end face of said 6 steel wires is connected with six contacts of said core wire respectively, the trapezoidal bottom of said 6 steel wires towards outside.
Moreover 6 internal layer thighs of said steel rope wrap the sth. made by twisting central strand symmetrically, and said 6 thicker inferior outer layer strand and 6 thinner inferior outer layer strand are wrapped sth. made by twisting symmetrically at the internal layer thigh lateral, and 16 outer layer strand are wrapped sth. made by twisting symmetrically in the steel rope outermost.
The beneficial effect of the utility model is following:
Because said steel bushing uses the 1Cr17Ni steel, said rigging adopts the 1*7-6*7-6*7/6*7-16*7 structure with steel rope.Said compaction-strand steel wire rope intensity of steel wire is selected 1960MPA, rupture pull force coefficient 0.41.This rigging load-carrying capacity improves 26.1% than common pressure-formed rigging, and rigging does not rotate under the state that does not carry.

The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Embodiment 1
As shown in Figure 1, a kind of high-lift lifting comprises steel rope, crimping noose with compacting thigh steel cable crimping rigging, and said crimping noose uses steel bushing not have polar ring, and rigging adopts compaction-strand steel wire rope with steel rope.Steel bushing uses the 1Cr17Ni steel.
As shown in Figure 2, rigging comprises central strand, internal layer thigh, inferior outer layer strand and outer layer strand with steel rope, and steel wire is face contact shape in each strand.Said rigging adopts the 1*7-4*19S/4*7-8*26WS structure with steel rope, and strand wire adopts the compacting thigh.The compaction-strand steel wire rope intensity of steel wire is selected 1960MPA, rupture pull force coefficient 0.41.
