Abstract
The invention provides a light-type high-strength steel wire rope core conveyor belt and solves the problems that a steel wire rope of a steel wire rope core is great if an existing steel wire rope core conveyor belt needs to achieve certain high strength so that the thickness of the conveyor belt is great and the weight is heavy. The light-type high-strength steel wire rope core conveyor belt comprises core rubber, the steel wire rope core, upper covering rubber, lower covering rubber and edge rubber; and the steel wire rope of the steel wire rope core comprises a rope core and a plurality of threads of steel wires A, and further comprises a thread of a steel wire B which is spirally entwisted at the periphery of the plurality of threads of steel wires A around the length direction of the steel wire rope. According to the conveyor belt, the strength of the single steel wire rope is enhanced and the diameter is reduced; the tight arrangement of the steel wire ropes in the steel wire rope core can be realized; compared with the existing conveyor belt, the conveyor belt with the same belt width and the same strength, the quantity of the steel wire ropes is greatly increased so that the thickness of the conveyor belt is greatly thinned and the unit weight is greatly reduced; and all performance parameters of the conveyor belt are optimized and the material cost and the transportation cost are saved.
Description
Technical field
The present invention relates to rubber conveyer belt, be specifically related to steel cable core conveying belt.
Background technology
Rubber conveyer belt has the characteristics such as heatproof zone, wear-resistant strip, the band of resistance to calcination, oil resistant band, alkaline-resisting band, alkaline-resisting band, heatproof zone, cold-resistant band.The solid material that is mainly used in the enterprises such as each mine, metallurgy, iron and steel, coal, water power, building materials, chemical industry, grain is carried.
Steel cable core conveying belt is a kind of in rubber conveyer belt, because its pulling strengrth is large, shock resistance is good, the life-span is long, use extend little, groove forming character good, flexible resistance good, is suitable for long distance, large length of run, high-speed convey materials.As shown in Figure 1, steel cable core conveying belt consists of core glue 1, Steel cord, upper rubber cover 3, lower rubber cover 4 and limit glue 5, by Steel cord, provides the required brute force of load-transfer device (being intensity).
In prior art, the Steel cord of steel cable core conveying belt steel rope 2 used consists of the steel wire strand of wire rope core and wire rope core periphery conventionally, first by multilayer steel wire, is twisted thigh, then centered by wire rope core, by some thighs, twists with the fingers helically wound rope.Because the brute force of steel cable core conveying belt is mainly provided by Steel cord, if reach the high-tenacity requirement of certain load-transfer device, to be applicable to long distance, large length of run, high-speed convey materials, the steel rope general diameter larger (being generally 4-18mm) that Steel cord is used, the spacing of the adjacent wires rope of the steel wire rope core of conveyer belt after moulding large (being generally 10-20mm), load-transfer device thickness and larger from weight average, correspondingly, load-transfer device carrying resistance, become into a tension force, antivertex tension force is all larger, thereby make the productive costs of steel cable core conveying belt, carry cost all higher, and so thick and heavy batching of load-transfer device deposited, turnings in course of conveying etc. are all more difficult.Take model as ST3500(be that steel rope brute force is 3500KN) steel cable core conveying belt be example, its each parameter value is as shown in the table.
Steel cable core conveying belt parameter (model: ST3500)
Summary of the invention
The invention provides a kind of light-duty high-strength power steel cable core conveying belt, if can solve prior art steel cable core conveying belt, will reach certain high-tenacity, the wirerope diameter of Steel cord is large, causes the problem that load-transfer device thickness is large, weight is large.
For reaching above-mentioned technical purpose, the present invention is achieved by the following technical solutions: a kind of light-duty high-strength power steel cord conveyor belt, comprise core glue, Steel cord, upper rubber cover, lower rubber cover and limit glue, the steel rope of described Steel cord comprise wire rope core and centered by wire rope core along wire rope core length direction twist with the fingers around steel wire strand A, the periphery that the steel rope of described Steel cord is also included in described steel wire strand A along the length direction spiral turn of steel rope around one steel wire B.
Described steel wire B spiral turn around pitch be 4-6mm, the diameter of described steel wire B is 0.2-0.8mm, the wirerope diameter of described Steel cord is 3-6mm.
The spacing of the adjacent wires rope of described Steel cord is 1-3mm.
The thickness of described load-transfer device is 8-16mm.
When bandwidth is 1000mm, the unit weight of described load-transfer device is 9-33kg/m.
Compared with prior art, light-duty high-strength power steel cable core conveying belt of the present invention, because the peripheral spiral turn of the steel wire strand A of Steel cord is wound with another gang of steel wire B, thereby make the whole winding of steel rope tightr, greatly strengthened its intensity, if thereby reach the intensity same with existing steel rope, can make the diameter of single wire rope greatly reduce, thereby can realize the close-packed arrays of steel rope in Steel cord, same band, the load-transfer device of the present invention of identical brute force is compared with existing load-transfer device, steel rope radical increases greatly, the thickness that makes load-transfer device is attenuate greatly, unit weight reduces greatly, optimized each performance perameter of load-transfer device, saved material cost, traffic cost.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
With reference to shown in Fig. 2 to Fig. 4, the present embodiment light-duty high-strength power steel cable core conveying belt, comprise core glue 1, Steel cord, upper rubber cover 3, lower rubber cover 4 and limit glue 5, Steel cord is between upper rubber cover 3 and lower rubber cover, it comprises along the many steel ropes 2 of load-transfer device Width arrangement in parallel, is described core glue 1 between adjacent wires rope 2.Steel rope 2 comprise wire rope core 2.1 and centered by wire rope core 2.1 along wire rope core 2.1 length directions twist with the fingers around steel wire strand A2.2, for meeting on the basis of steel rope 2 requirement of strength, reduce as far as possible steel rope 2 diameters, steel rope 2 also comprises one steel wire B2.3, steel wire B2.3 in the periphery of steel wire strand A2.2 along the length direction spiral turn of steel rope around, steel wire B2.3 at the outer sth. made by twisting of placing of steel wire strand A2.2 around the sth. made by twisting of same steel wire strand A2.2 around mode.
Concrete, steel wire B2.3 the peripheral spiral turn of steel wire A2.2 around pitch t be 4-6mm, the diameter range of steel wire B2.3 is 0.2-0.8, thereby make the whole winding of steel rope tightr by twisting with the fingers around steel wire B2.3, greatly strengthened its intensity, compare existing steel rope, if reach identical intensity, in the present embodiment, the diameter of Steel cord steel rope 2 used can be decreased to 3-6mm greatly.
The spacing L of adjacent wires rope 2 is 1-3mm.
