Abstract
The utility model relates to a double-compaction steel wire rope for hanging and belongs to the field of the steel wire rope. The double-compaction steel wire rope for hanging comprises a center sub rope and an outer layer strand, wherein the outer layer strand surrounds the center sub rope, the center sub rope comprises a center strand and an inner layer strand surrounding the center strand, the outer layer strand comprises an inner layer wire, a secondary outer layer fine wire, a secondary outer layer thick wire and an outer layer wire which are distributed layer by layer by using a center wire as the center and mutually surround, the center sub rope and the outer layer strand are in surface contact, the center strand and the inner layer strand are in surface contact, and the outer layer strand is in a trapezoidal shape. The double-compaction steel wire rope has the advantages that the strand compaction is firstly adopted, and then, the rope compaction technology is adopted for changing the line contact between the rope and the strands as well as between the strands into the surface contact, and the problem that the line contact exists in the steel wire rope is solved, so the bearing capability of the steel wire rope is improved by 40 percent, and the service life is prolonged by more than 60 percent.
Description
Technical field
The utility model relates to a kind of lifting with two compacting steel wire ropes, belongs to the steel wire rope field.
Background technology
The at present domestic 6*36WS series linear contact lay wire rope that generally uses of lifting steel wire rope; This steel wire rope is owing to unreasonable structure, and the rupture pull force coefficient only has 0.356, and bearing capacity is poor; Anti-wear performance is undesirable; Service life is low, when lifting, is easy to occur production accident based on above reason, and because the undesirable product rejection rate of anti-wear performance is also very high.
The utility model content
The purpose of the utility model, poor in order to solve above-mentioned lifting steel wire rope bearing capacity exactly, anti-wear performance is undesirable, and the problem that service life is low provides a kind of novel lifting with two compacting steel wire ropes.
In order to achieve the above object, the utility model adopts following technical scheme:
The two compacting steel wire ropes of a kind of lifting; Comprise middle center rope and be enclosed in middle center rope outer layer strand on every side; The center rope comprises central strand and is enclosed in central strand internal layer thigh on every side in said, and said outer layer strand comprises with central hair being internal layer silk, inferior outer filaments, inferior outer crin and the outer silk of successively arranging and surround each other in the center.
As preferably, middle center rope is that face contacts with outer layer strand.
As preferably, central strand is that face contacts with the internal layer thigh.
As preferably, it is trapezoidal that outer layer strand is.
The utility model makes it compared with prior art owing to adopted above technical scheme, has the following advantages and characteristics:
1. the rupture pull force coefficient obviously improves.Bearing capacity strengthens.
2. ABRASION RESISTANCE has had large increase, and prolong service life.
3. increase coefficient safe in utilization.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model.
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.
The two compacting steel wire ropes of a kind of lifting; Comprise middle center rope and be enclosed in middle center rope outer layer strand 3 on every side; Middle center rope comprises central strand 1 and is enclosed in central strand internal layer thigh 2 on every side outer layer strand 3 comprises with central hair being internal layer silk, inferior outer filaments, inferior outer crin and the skin silk of successively arranging and surround each other in the center.
Middle center rope is that face contacts with outer layer strand.Central strand 1 contacts for face with internal layer thigh 2.It is trapezoidal that outer layer strand is.
Outer layer strand is contacted by line through the extrusion process processing with middle center rope and becomes face contact shape.In the central strand of center rope cross extrusion process with the internal layer stock-traders' know-how that is enclosed in around the central strand, also be face contact shape each other.When outer layer strand is twisted with the fingers burst also extrusion process be face contact shape it comprise central hair, internal layer silk, inferior outer filaments, inferior outer crin and outer silk.Each strand is extruded after closing rope once more, and outer layer strand is approximate ladder type shape.Handling the steel wire rope effective bearing area through extrusion process increases, and activity coefficient increases, and bearing capacity improves 40%, and improve more than 60% service life.
What should explain at last is: the above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (4)
1. a lifting is with two compacting steel wire ropes; It is characterized in that: comprise middle center rope and be enclosed in middle center rope outer layer strand on every side; The center rope comprises central strand and is enclosed in central strand internal layer thigh on every side in said, and said outer layer strand comprises with central hair being internal layer silk, inferior outer filaments, inferior outer crin and the outer silk of successively arranging and surround each other in the center.
2. based on the two compacting steel wire ropes of the described a kind of lifting of claim 1, it is characterized in that: middle center rope is that face contacts with outer layer strand.
3. a kind of lifting according to claim 1 is with two compacting steel wire ropes, and it is characterized in that: central strand is that face contacts with the internal layer thigh.
4. a kind of lifting according to claim 1 is with two compacting steel wire ropes, and it is characterized in that: outer layer strand is trapezoidal.
