刮板输送机技术发展历程(二)——国内技术

The development history of scraper conveyor technology(Part two):technologies in China

我国生产刮板输送机始于1950年,以仿制苏联刮板输送机为主。1954年开始定型生产SGD-11型、SGB-11、SGB-15型刮板输送机;1958年试制出可弯曲链板输送机。1970年,国产SGW-150型刮板输送机与MLQ1-80型采煤机、TZ140型液压支架组成中国第一个采用自主装备的综采工作面。截至2020年底,我国累计生产煤矿刮板输送机19.43万台,其中张家口煤矿机械公司生产60 360台,宁夏天地奔牛公司生产24 840台。自2010年起,智能化刮板输送机开始起步,2011年研制成功国内首台初级智能化刮板输送机成套设备,2012年研制成功变频一体电机驱动的中双链刮板输送机,2014年研制成功世界首台具有装载量监测和自适应调速的智能控制刮板输送机。2022年研发出500 m长运距智能刮板输送成套装备,输送能力达3 000t/h;2023年研制出世界首套10m超大采高智能刮板输送机成套装备,输送能力为8 000t/h。我国刮板输送机单机平均吨位呈现指数型增长,20世纪50年代的单机平均吨位仅为5.3t,之后40年的刮板输送机处于小型化阶段;2000年单机平均吨位达到45t,进入重型化时期,2010年达到75t;之后进入超重型机型阶段,2020年单机平均吨位达161t。

The production of scraper conveyor in China began in 1950,mainly imitating the scraper conveyor of Soviet Union.China began to produce the SGD 11,SBG 11,SBG 15 scraper conveyor in 1954,and a flexible chain plate transport aircraft was developed in 1958.The domestic SGW 150 scraper conveyor was made in 1970,which formed China's first fully mechanized mining face with MLQ180 shearer and TZ140 hydraulic support.By the end of 2020,China had produced a total of 194300 scraper conveyors,of which 60360 were produced by Zhangjiakou Coal Mine Machinery Company and 24840 were produced by Ningxia Tiandi Benniu Company.Since 2010,intelligent scraper conveyor put into practical application,the first complete sets of primary intelligent scraper conveyor equipment in China was successfully developed in 2011,the world's first intelligent control scraper conveyor with load monitoring and adaptive speed regulation was developed in 2014,a complete set of intelligent scraper conveyor equipment with a transportation length of 500 m and a conveying capacity of 3000 t/h was developed in 2022,the world's first complete set of intelligent scraper conveyor equipment for 10 m super-high mining face was developed with a conveying capacity of 8000 t/h in 2023.The average tonnage of a single scraper conveyor in China showed exponential growth,the average tonnage of a single machine in the 1950s was only 5.3 t,and the scraper conveyor in the following 40 years was in the miniaturization stage;in 2000,the average tonnage of a single machine reached 45 t,entering the heavy period by reaching 75 t in 2010;after that,the scraper conveyor came to the super-heavy model stage,the average tonnage of a single machine reached 161 t in 2020.
