Description

A kind of lifting is with compacting thigh steel cable casting rigging

Technical field

The utility model relates to a kind of rigging, is meant that specifically a kind of lifting is with compacting thigh steel cable casting rigging.

Background technology

Along with lifting being growing more intense of industry competition, market is to the also raising day by day of requirement of aspects such as the bearing capacity of rope rig and anti-fatigue life.At present, it is common round strand contact steel rope that the rigging on the market uses steel rope, and its rupture pull force coefficient is 0.356, and strength grade is 1770MPA, and bearing capacity is low.In addition, that common rigging heats in the course of processing is inhomogeneous, the socket deflection is big, and the intensity of rigging approximates the 85%-90% of steel rope intensity, and service life is short.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides all good liftings of a kind of resistance to abrasion, crush resistance and resistance to shock loads performance with compacting thigh steel cable casting rigging.

The technical scheme that solves the problems of the technologies described above is:

A kind of lifting comprises casting socket, steel rope with compacting thigh steel cable casting rigging, and steel rope and socket adopt the mode of casting to be formed by connecting; Said casting socket adopts cast iron materials; Said steel rope uses compaction-strand steel wire rope, and said steel rope comprises central strand, internal layer thigh, fills thigh and outer layer strand, and the internal layer thigh of said steel rope wraps the sth. made by twisting central strand symmetrically; The said strand external series gap that is positioned at adjacent two internal layer thighs of filling, said outer layer strand is wrapped sth. made by twisting symmetrically in the steel rope outermost.

Further, be line contact shape between the steel wire of said central strand, internal layer thigh, filling thigh and connect, and be twisted together.

Moreover said central strand comprises core wire, 18 thicker wires and 6 finer wires; 6 said thicker wires wrap symmetrically twists with the fingers said core wire, and 6 said finer wires are positioned at the external series gap of adjacent two thicker wires, and 12 said thicker wires wrap sth. made by twisting symmetrically in the central strand outermost.

Moreover said internal layer thigh comprises core wire, 10 finer wires, 5 middle finer wires and 10 thicker wires; 5 said finer wire bags are twisted with the fingers said core wire, and its outer staggered bag is twisted with the fingers and is provided with 5 middle finer wires and 5 finer wires, and 10 said thicker wires wrap sth. made by twisting symmetrically in internal layer thigh outermost.

Moreover said filling thigh comprises core wire and 6 cover wires; Said 6 cover wires wrap the sth. made by twisting core wire symmetrically.

Moreover; The core wire cross section of said outer layer strand is approximate regular hexagon; 6 section of steel wire of the skin of said outer layer strand are approximate trapezoid shapes 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.

Because the structure of steel rope outer layer strand is face contact shape through the mould extruding, has improved steel rope metal payload space, the rupture pull force coefficient of steel rope is high, resistance rotation performance is good, has stronger resistance to abrasion, crush resistance and resistance to shock loads performance.Simultaneously, rigging homogeneous heating, socket deflection in the course of processing is little, and the intensity of steel rope casting rigging intensity and used steel rope is identical; Compare common casting rigging; It is nearly 36.9% that its load-carrying capacity can improve, and therefore whole rope rig has higher capacity, long service life.

Mark is illustrated as among Fig. 1-6, and 1 casting socket, 2 steel ropes, 3 central strand, 4 internal layer thighs, 5 are filled thigh, 6 outer layer strand.

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.

Shown in Fig. 1-6, a kind of lifting comprises casting socket 1, steel rope 2 with compacting thigh steel cable casting rigging.Casting socket 1 adopts cast iron materials, and steel rope 2 uses compaction-strand steel wire rope.

Steel rope 2 comprises central strand 3, internal layer thigh 4, fills thigh 5 and outer layer strand 6.The internal layer thigh 4 of steel rope 2 wraps symmetrically twists with the fingers central strand 3, fills the external series gap that thigh 5 is positioned at adjacent two internal layer thighs 4, and outer layer strand 6 is wrapped symmetrically and twisted with the fingers in the steel rope outermost.

Be line contact shape between the steel wire of central strand 3, internal layer thigh 4, filling thigh 5 and connect, and be twisted together.

Central strand 3 comprises core wire, 18 thicker wires and 6 finer wires; 6 thicker wires wrap the sth. made by twisting core wire symmetrically, and 6 finer wires are positioned at the external series gap of adjacent two thicker wires, and 12 thicker wires wrap sth. made by twisting symmetrically in the central strand outermost.

Internal layer thigh 4 comprises core wire, 10 finer wires, 5 middle finer wires and 10 thicker wires; 5 finer wire bags are twisted with the fingers core wire, and its outer staggered bag is twisted with the fingers and is provided with 5 middle finer wires and 5 finer wires, and 10 thicker wires wrap sth. made by twisting symmetrically in internal layer thigh outermost.

Fill thigh 5 and comprise core wire and 6 cover wires; 6 cover wires wrap the sth. made by twisting core wire symmetrically.

The core wire cross section of outer layer strand 6 is approximate regular hexagons; 6 section of steel wire of the skin of outer layer strand 6 are approximate trapezoid shapes and connect into ring through trapezoidal side edges, the trapezoidal end face of these 6 steel wires is connected with six contacts of core wire respectively, the trapezoidal bottom of 6 steel wires towards outside.

Its method for making is:

On sth. made by twisting thigh car, arranged steel wire through distributing terminal board, process is closed up mouth and is compressed, and the stress of process post-former actv. elimination thigh is received on the I-beam wheel then again, gets central strand 3, internal layer thigh 4, filling thigh 5.The making of outer layer strand 6; On sth. made by twisting strand car, arranged steel wire through distributing terminal board; Through close up mouthful with the wolfram steel mould be compacted to steel rope be deformed to desired structure, through the stress that post-former is effectively eliminated strand, be received on the I-beam wheel, carry out (cold-)drawn (steel)wire with mould again and restrict; Change wire shape in the outer layer strand 6, make the interior steel wire of outer layer strand be face contact shape.

Close when restricting, on entire vehicle, arrange central strand 3, internal layer thigh 4, filling thigh 5 and outer layer strand 6 through distributing terminal board, through pre-former, compress through closing up mouth again, the process post-former is effectively eliminated the stress of thigh again, is received on the I-beam wheel then.

Scattered in the steel rope termination, clean, penetrate in the socket, to the socket preheating, with the tin-lead alloy casting cooling of fusion, be prepared into compacting thigh steel cable casting rigging again with diathermic heating.

Because the structure of rope strand is face contact shape through the mould extruding, has improved steel rope metal payload space, the rupture pull force coefficient of steel rope is high, resistance rotation performance is good, has stronger resistance to abrasion, crush resistance and resistance to shock loads performance.
