Abstract
The utility model discloses a high breaking load traction steel belt for an elevator, and provides a steel belt with high breaking load and long service life. A plurality of galvanized steel wire ropes are arranged and coated in a composite material layer at equal intervals; 6 to 24 galvanized steel wire ropes are arranged; and the diameter of each galvanized steel wire rope is 1.6-5.0mm; the galvanized steel wire ropes have a structure of 6*7+IWS or 6*19S+IWR; and the surface of each galvanized steel wire rope is provided with a polyurethane coating in the thickness of 1-2mm. According to the steel belt, the steel wire ropes with special structures have high strength, and the number of the steel wire ropes can be reduced under the requirement on the same breaking force, so that the breaking load is improved and the service life is long. In the steel belt, 6 to 24 galvanized steel wire ropes in the diameter of 1.6-5.0mm are arranged at equal intervals, the rope-diameter ratio of the steel wire ropes to a traction sheave can be effectively reduced, and the flexible life of the steel wire ropes is greatly prolonged.
Description
Technical field
The utility model relates to the steel rope technical field, particularly relates to a kind of high Breaking load elevator traction steel band.
Background technology
Along with increasing of high-rise, the consumption of elevator continues to increase.Traditional towed elevator all is to adopt steel rope to carry out traction.Steel rope weares and teares easily, service life short, needs lubricated.In order to overcome above-mentioned defective, adopt composite steel band to replace steel rope at present.Because steel rope is coated in the composite material, steel rope and traction sheave directly do not produce friction, and improve the service life of composite steel band greatly, and noise reduces greatly.
The traction steel band is overlayed in the composite material by the many equidistant arrange packets of galvanized steel wire rope to be formed.
Adopt the steel wire strand of 1 * 7 structure to form steel band at present.Because the intensity of this structure steel rope is lower, the used wirerope diameter of traction steel band is subjected to the dimensional restriction of steel band own, and rupture pull force is less, can only satisfy the higher loading requirement of traction steel band itself by increasing radical.But the steel rope radical is more to cause in the production process each tension force to be difficult to regulate consistent easily, causes steel band Breaking load defect of insufficient, the service life of having reduced steel band.
The utility model content
The purpose of this utility model is at the technological deficiency that exists in the prior art, and provides a kind of cripping load height, the high Breaking load elevator traction steel band of long service life.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of high Breaking load elevator traction steel band, the many equidistant arrange packets of galvanized steel wire rope overlay in the composite layer, the quantity of described galvanized steel wire rope is 6 to 24, the diameter of every described galvanized steel wire rope is 1.6-5.0mm, and the structure of every described galvanized steel wire rope is 6 * 7+IWSC or 6 * 19S+IWRC.
The surface of every described galvanized steel wire rope is provided with the polyurethane coating that thickness is 1-2mm.
Compared with prior art, the beneficial effects of the utility model are:
1, steel band of the present utility model is by adopting the steel rope of ad hoc structure, and the intensity height of steel rope under the requirement of same rupture pull force, can reduce the usage quantity of steel rope, thereby improves cripping load, long service life.
2, in the steel band of the present utility model, be that the galvanized steel wire rope of 1.6-5.0mm is equidistantly arranged by 6 to 24, diameter, the rope that can actv. reduces steel rope and traction sheave directly than, improve the armored rope bending fatigue life-span greatly.
3, in the steel band of the present utility model, at steel rope surface coating one deck polyurethane material, can improve steel rope surface corrosion stability and resistance to abrasion, can effectively improve simultaneously and traction sheave between friction coefficient, reduce the noise in the use.
Description of drawings
Figure 1 shows that the high Breaking load elevator of the utility model section-drawing of traction steel band;
Figure 2 shows that the structural representation of 6 * 7+IWSC structure steel rope;
Figure 3 shows that the structural representation of 6 * 19S+IWRC structure steel rope.
Among the figure: 1. composite layer, 2. galvanized steel wire rope.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The scheme drawing of the high Breaking load elevator usefulness of the utility model traction steel band as shown in Figure 1, many galvanized steel wire rope 2 equidistant arrange packets overlay in the composite layer 1, the quantity of described galvanized steel wire rope 2 is 6 to 24, the diameter of every described galvanized steel wire rope is 1.6-5.0mm, the structure of described galvanized steel wire rope 2 is 6 * 7+IWS or 6 * 19S+IWR, its scheme drawing such as Fig. 2, shown in Figure 3.
The surface of every described galvanized steel wire rope is provided with the polyurethane coating that thickness is 1-2mm.
Specification with the utility model structure is that 3 * 30 traction steel band minimum breaking force can reach 32kN, and the rupture strength of the steel band that the steel rope of the existing structure of comparing is formed improves about 25%.
The above only is preferred implementation of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. one kind high Breaking load elevator traction steel band, the many equidistant arrange packets of galvanized steel wire rope overlay in the composite layer, it is characterized in that, the quantity of described galvanized steel wire rope is 6 to 24, the diameter of every described galvanized steel wire rope is 1.6-5.0mm, and the structure of every described galvanized steel wire rope is 6 * 7+IWSC or 6 * 19S+IWRC.
2. high Breaking load elevator traction steel band according to claim 1 is characterized in that the surface of every described galvanized steel wire rope is provided with the polyurethane coating that thickness is 1-2mm.
