Abstract
The utility model provides a polyurethane steel cord conveyor belt which has the advantages of improved abrasion-resistant, shock-resistant and dynamic fatigue-resistant performances and prolonged service life. The utility model adopts the technical scheme that the conveyor belt comprises upper covering adhesive (1) and lower coating adhesive (2), and is characterized in that both the upper covering adhesive (1) and the lower coating adhesive (2) are polyurethane adhesive; and a wire rope core (3) serving as a framework material is arranged between the upper covering adhesive (1) and the lower coating adhesive (2), and comprises wire ropes arranged longitudinally at equal intervals.
Description
Technical field
The utility model belongs to steel cord conveyor belt device field, especially a kind ofly improves the polyurethane steel wire rope load-transfer device that wear and shock-resistant performance and dynamic fatigue resistance can and increase the service life.
Background technology
Steel cord conveyor belt is the major part of belt conveyer, is mainly used in the large-scale continuous transportation of departments such as coal, mine, metallurgy, chemical industry, building and traffic, and the material of transportation is divided into bulk, powdery, pasty state and member article etc.
Effort through over half a century; Modern load-transfer device has solved insoluble problem of many past, and be considered to solve in modernized material transporting and the processing that environment, the energy, traffic, space are crowded, one of labour power and the most cost-effective mode of production security.Along with continuous progress in science and technology, universal gradually and the application of up-to-date technology, new installation, industrial degree of automation significantly improves, and the range of use of load-transfer device is more and more wider, and the market demand will increase year by year.
China is that world's load-transfer device is produced and consumption big country.According to the industry rough Statistics, about 2.5 hundred million m of the yearly capacity of present national load-transfer device
2, productive capacity ranks the first in the world.In general, the load-transfer device product of China is to be self-sufficient and achieve a surplus, and section port is arranged, but because description and defect level are limit and other factors, all needs the part import every year.
Since the recent two decades, China's load-transfer device production development is very fast, and except that individual product, kind series is synchronous with the world basically, and in line with international standards.On product quality level, note timely adoption of international standard and advanced oversea standard.The load-transfer device that present China makes skeleton with syntheticfibres and Steel cord has accounted for 90% of load-transfer device output, near international most advanced level.Country had implemented the production licence system to the fire retarding conveying band product again in 2003, and this defect level to China's load-transfer device product is one again and promotes greatly.But in general, the intensity of China's load-transfer device and width series, presentation quality and service life, than international most advanced level still have gap.
Polyurethane (composite material) is made with heat-curable urethane.This composite material has superior tensile, impact resistance and corrosion stability.The about 880kg/cm of its typical pulling strengrth
2, the about 30230kg/cm of tensile modulus
2, breaking elongation is more than 7.5%.Through the foaming polyurethane (composite material) but also loss of weight reach 20%.Compare with other resins such as unsaturated polyester (UP), vinyl esters, polyurethane has improved the physical property of product comprehensively.
The main dependence on import of China's rubber in addition, and load-transfer device industry is the important industry that is only second to tire industry in the rubber industry.We adopt polyurethane conduct wear-resisting layer covering up and down, are not only a great change of load-transfer device industry, also and for entire society positive benefit are arranged all.
The utility model content
The purpose of the utility model provides a kind of polyurethane steel wire rope load-transfer device that wear and shock-resistant performance and dynamic fatigue resistance can and increase the service life that improves.
The technical scheme of the utility model is: polyurethane steel wire rope load-transfer device; Comprise rubber cover (1), following rubber cover (2); It is characterized in that said upward rubber cover (1) and following rubber cover (1) are polyurethane adhesive, are provided with Steel cord (3) as framework material between the rubber cover (2) down at last rubber cover (1).
The steel rope that described Steel cord (3) is arranged by vertical determining deviation is formed.
The effect of the utility model is: polyurethane steel wire rope load-transfer device, last rubber cover is polyurethane adhesive with following rubber cover, is being provided with Steel cord as framework material between the rubber cover under the last rubber cover.The steel rope that Steel cord is arranged by vertical determining deviation is formed.
The steel rope that the utility model adopts vertical determining deviation to arrange is a core, and with polyurethane as elastic body, bulk strength is high, the stretch-proof performance is good, shock-resistant, wear-resisting, water-fast, oil resistant can significantly improve the in-use performance and the service life of load-transfer device.Have flame retardance in addition in addition, antistatic property is applicable to convey materials under high strength, long distance, the large conveying quantity occasion, is particularly suitable for convey materials under the coal mine.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
Description of drawings
Fig. 1 is the utility model structural representation;
The construction of wire rope scheme drawing that the vertical determining deviation of Fig. 2 the utility model is arranged.
The specific embodiment
Among Fig. 1; Polyurethane steel wire rope load-transfer device; Comprise rubber cover 1, following rubber cover 2; Last rubber cover 1 is polyurethane adhesive with following rubber cover 1, between 1 time rubber cover 2 of last rubber cover, is provided with Steel cord 3 as framework material, and the steel rope that Steel cord 3 is arranged by vertical determining deviation is formed (referring to Fig. 2).The spacing of steel rope, diameter, radical all are to adjust according to requirement of strength.
Claims (2)
1. polyurethane steel wire rope load-transfer device comprises rubber cover (1), following rubber cover (2), it is characterized in that said upward rubber cover (1) and following rubber cover (1) are polyurethane adhesive, are provided with Steel cord (3) as framework material between the rubber cover (2) down at last rubber cover (1).
2. polyurethane steel wire according to claim 1 rope load-transfer device is characterized in that the steel rope that described Steel cord (3) is arranged by vertical determining deviation forms.
