Abstract
A kind of high lift lifting compacting stock steel cable pressure-welded rigging, structure include steel wire rope, crimping noose, and for the crimping noose using steel bushing without polar ring, rigging uses compaction-strand steel wire rope with steel wire rope.The steel wire rope includes central strand, internal layer stock, secondary outer layer strand and outer layer strand, and steel wire contacts shape in face in each stock.The internal layer stock of the steel wire rope, which symmetrically wraps, twists central strand.The secondary outer layer strand includes that thicker secondary outer layer strand and relatively thin outer layer strand, their alternatings symmetrically wrap twirl in internal layer thigh lateral.The outer layer strand symmetrically wraps twirl in steel wire rope outermost.
Description
Technical field
The present invention relates to a kind of rigging and preparation method thereof, in particular to a kind of high lift lifting compacting stock steel cable crimping
Rigging.
Background technology
With the competition in lifting market, lifting increasingly emphasizes stability and high-mechanic with rigging.Currently,
Lifting rigging uses aluminium alloy casing, steel wire rope to justify stock structure steel wire rope using 35W*7.Breaking force of rope coefficient
0.36, strength grade 1770MPA, rigging bearing capacity are low.
Invention content
In order to solve the above technical problem, the present invention provides all good lifting riggings of a kind of stability and bearing capacity.
Solving the technical solution of above-mentioned technical problem is：
A kind of high lift lifting compacting stock steel cable pressure-welded rigging, structure include steel wire rope, crimping noose, the crimping
For noose using steel bushing without polar ring, rigging uses compaction-strand steel wire rope with steel wire rope.The steel wire rope include central strand, internal layer stock,
Secondary outer layer strand and outer layer strand, steel wire contacts shape in face in each stock.
It is further improved as the steel bushing uses 1Cr17Ni steel, the rigging to use 1*7-6*7-6*7/6* with steel wire rope
7-16*7 structures.
Furthermore the compaction-strand steel wire rope intensity of steel wire selects 1960MPA, rupture pull force coefficient 0.41.
Furthermore the internal layer stock of the steel wire rope, which symmetrically wraps, twists central strand.The secondary outer layer strand includes thicker secondary outer layer
Stock and relatively thin outer layer strand, alternately symmetrically packet is twisted in internal layer thigh lateral for they.The outer layer strand symmetrically wraps twirl in steel wire rope
Outermost.
Furthermore the central strand, internal layer stock, secondary outer layer strand and outer layer strand core wire section be approximate regular hexagon
Shape, 6 section of steel wire of the outer layer connect cyclization in approximate trapezoid shape and by trapezoidal side edges, 6 steel wires it is trapezoidal
Top surface is connected with six faces of the core wire respectively, and the trapezoidal bottom of 6 steel wires faces out.
Furthermore 6 internal layer stocks of the steel wire rope, which symmetrically wrap, twists central strand, described 6 thicker secondary outer layer strands and 6
Thinner secondary outer layer strand symmetrically wraps twirl in internal layer thigh lateral, and 16 outer layer strands symmetrically wrap twirl in steel wire rope outermost.
Beneficial effects of the present invention are as follows：
Since the steel bushing uses 1Cr17Ni steel, the rigging to use 1*7-6*7-6*7/6*7-16* with steel wire rope
7 structures.The compaction-strand steel wire rope intensity of steel wire selects 1960MPA, rupture pull force coefficient 0.41.This rigging bearing capacity ratio
The rigging commonly suppressed improves 26.1%, and rigging does not rotate in the state of not carrying.
Specific implementation mode
Embodiment 1
A kind of high lift lifting compacting stock steel cable pressure-welded rigging, including steel wire rope, crimping noose, the crimping noose make
With steel bushing without polar ring, rigging uses compaction-strand steel wire rope with steel wire rope.Steel bushing uses 1Cr17Ni steel.Rigging includes with steel wire rope
Central strand, internal layer stock, secondary outer layer strand and outer layer strand, steel wire contacts shape in face in each stock.The rigging uses 1*7- with steel wire rope
4*19S/4*7-8*26WS structures, strand wire is using compacting stock.Compaction-strand steel wire rope intensity of steel wire selects 1960MPA, fracture
Tension coefficient 0.41.
Its production method is：
Carry out cold-drawn steel cord rope strand with mold when twisting stock using the mode of production of die drawing, change in stock wire shape but
Substantially the cross-sectional area for not changing steel wire makes to contact shape in face between steel wire and steel wire in rope strand, is prepared into strand wire.It is per share equal
A core wire 1 is twisted by 6 cover wire packets to form, wherein cover wire approximate trapezoid, approximate positive six side of core wire
Shape contacts shape in stock between steel wire and steel wire in face.
When closing rope, first central strand is twisted by 6 internal layer stock packets and arranged by noseplate on finished car, by predeformation
Device, then compressed by closing up mouth, the stress of stock is effectively eliminated using post-former, is then received in I-beam wheel and is formed son
Rope, then arranged by noseplate on finished car by 6 time outer layer strands and 6 filling stock packet spill ropes, by pre-former,
It is compressed again by closing up mouth, the stress of stock is effectively eliminated using post-former, be then received in I-beam wheel and form son rope, most
It is arranged afterwards by noseplate on finished car by 16 outer layer strand packet spill ropes, by pre-former, then by closing up mouth pressure
Tightly, the stress of stock is effectively eliminated using post-former, is then received in I-beam wheel and is formed steel wire rope.The twist direction of outer layer strand with
Interior two layers strand of twist direction is opposite.
Steel bushing connector is finally determined according to rigging specification, then determines mold, carries out rope rig compacting.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
With technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
