Abstract
A steel cable for household small-sized elevators is 6mm in specification and consists of a center strand, eight inner strands and eight outer strands, wherein the center strand is wrapped by the inner strands in a symmetrical linear-contact form and the outer strands are wrapped on the outmost side of the steel cable in a symmetrical linear-contact form. As the steel cables are stranded by eight outer strands wrapping the center strand, the diameter uniformity of the steel cable is improved greatly when compared with a steel cable with a hemp center, has better fatigue resistance, higher breaking force and lower extensibility, and is applicable to household small-sized elevators.
Description
Technical field
The utility model relates to a kind of steel wire rope, specifically is meant household small-size elevator steel wire rope.
Background technology
Along with the continuous progress of society, multiple layer household is increasing, and the household small-size elevator is also popular gradually, and its required steel wire rope specification is little, and diameter poker uniformity will be got well, and it is high that rupture pull force is wanted, and anti-fatigue performance will be got well.At present, the special-purpose hoist ropes production and selling of elevator that does not still have this specification.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of specification little (¢ 6mm), diameter poker uniformity, rupture pull force and anti-fatigue performance all good household small-size elevator steel wire ropes.
The technical scheme that solves the problems of the technologies described above is:
Household small-size elevator steel wire rope, its specification is ¢ 6mm, comprises central strand, 8 internal layer thighs and 8 outer layer strand, described internal layer thigh symmetrically, be line and wrap the sth. made by twisting central strand touchingly, described outer layer strand symmetrically, be line and wrap sth. made by twisting touchingly in the steel wire rope outermost.
Further be improved to, described outer stock internal layer and skin are Wa Lin and gulp down formula; 6 thick wires of described internal layer symmetrically, be line and wrap the sth. made by twisting core wire touchingly; Described skin comprises 6 thick wires and 6 finer wires, and wherein 6 thick wires are the recess that line embeds adjacent 2 steel wire of internal layer touchingly, and 6 finer wires are line and wrap the bossing of twisting with the fingers at 6 steel wire of internal layer touchingly respectively.
Described internal layer thigh be by 6 steel wires symmetrically, be line and wrap touchingly and twist with the fingers core wire and form.
Described center stock internal layer and skin are Wa Lin and gulp down formula; 6 thick wires of described internal layer symmetrically, be line and wrap the sth. made by twisting core wire touchingly; Described skin comprises 6 thick wires and 6 finer wires, and wherein 6 thick wires are the recess that line embeds adjacent 2 steel wire of internal layer touchingly, and 6 finer wires are line and wrap the bossing of twisting with the fingers at 6 steel wire of internal layer touchingly respectively.
Because center rope (combination of central strand and internal layer thigh) is to twist with the fingers a central strand twisting by 8 sub-threads (internal layer thigh) bag to form in described, its each sub-thread be by 6 steel wires symmetrically, be line and wrap touchingly and twist with the fingers core wire and form, the contrast hemp center wireline, so just improve the uniformity of the rupture pull force and the rope footpath poker of steel wire rope greatly, also had fatigue behaviour preferably.8 * 19S+NF steel wire rope of contrast same size, intensity, this structure breaking force of rope has improved 19%, and diameter range requires+1%~+ 4%, because the steel wire rope specification is 6mm, is fit to the household small-size elevator and uses.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the cross section structure schematic diagram of the utility model household small-size elevator with steel wire rope;
Fig. 2 is the central strand cross section structure schematic diagram of the utility model household small-size elevator with steel wire rope;
Fig. 3 is the internal layer thigh cross section structure schematic diagram of the utility model household small-size elevator with steel wire rope;
Fig. 4 is the outer layer strand cross section structure schematic diagram of the utility model household small-size elevator with steel wire rope;
Mark is illustrated as among Fig. 1-4,1 central strand, 2 internal layer thighs, 3 outer layer strand.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, household small-size elevator steel wire rope, its specification is ¢ 6mm, comprises 1,8 internal layer thighs 2 of central strand and 8 outer layer strand 3, internal layer thigh 2 symmetrically, be line and wrap touchingly and twist with the fingers central strand 1, outer layer strand 3 symmetrically, be line and wrap sth. made by twisting touchingly in the steel wire rope outermost.
As Fig. 2, shown in Figure 4, central strand 1 and outer layer strand 3 are all divided internal layer and skin, are Wa Lin and gulp down formula; 6 thick wires of internal layer symmetrically, be line and wrap the sth. made by twisting core wire touchingly; Skin comprises 6 thick wires and 6 finer wires, and wherein 6 thick wires are the recess that line embeds adjacent 2 steel wire of internal layer touchingly, and 6 finer wires are line and wrap the bossing of twisting with the fingers at 6 steel wire of internal layer touchingly respectively.As shown in Figure 3, the internal layer thigh be by 6 steel wires symmetrically, be line and wrap touchingly and twist with the fingers core wire and form.
Its preparation method is: arranged steel wire by noseplate on sth. made by twisting strand car, produce desired structure through closing up to compress mouthful with the line ball punching block, effectively eliminate the stress of thigh again through post-former, be received in then on the I-beam wheel, be prepared into Wa Lin and gulp down formula central strand 1, internal layer thigh 2 and outer layer strand 3.
When closing rope, twisting with the fingers central strand 1 by 8 internal layer thighs, 2 bags earlier arranges by noseplate on finished car, through pre-former, compress by closing up mouth again, eliminate the stress of thigh more effectively through post-former, be received in then and form the son rope on the I-beam wheel, arrange by noseplate on finished car by 8 outer layer strand, 3 bag spill ropes again,, compress by closing up mouth again through pre-former, effectively eliminate the stress of thigh again through post-former, be received in then and form steel wire rope on the I-beam wheel.
Because center rope (combination of central strand and internal layer thigh) is to twist with the fingers a central strand twisting by 8 sub-threads (internal layer thigh) bag to form in described, its each sub-thread be by 6 steel wires symmetrically, be line and wrap touchingly and twist with the fingers core wire and form, so just improved the directly uniformity of poker of the rupture pull force of steel wire rope and rope greatly.8 * 19S+NF steel wire rope of contrast same size, intensity, this structure breaking force of rope has improved 19%, and diameter range requires+1%~+ 4%, because the steel wire rope specification is 6mm, is fit to the household small-size elevator and uses.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
