Description
Technical field
The present invention relates to combined job that requires special skills equipment technical field, particularly relate to a kind of highway and railway two-purpose rail and to remove sand car sand discharge apparatus.
Background technology
From since the establishment of the nation, China railways system obtains to improve and develops fast, and relevant transport goods and materials are also varied.From coal, oil and metal to timber, the dispensing of grain, chemical fertilizer and other items, be all born by the railway traffic of prosperity without exception.Moreover, the prosperity of these relevant to railway up to a hundred industries is all firmly known by the railway system of China with decline.In addition, according to related data statistics, China has the colliery choice for use train transport of 10 tons nearly, accounts for more than 4/5ths of the total colliery of China.Steel industry has the choice for use train transport more than 5 tons.Petroleum industry has the selection train transport more than 1 tons.The goods and materials such as agriculture and animal husbandry chemical fertilizer have 70,000,000 tons of use train transports nearly.Further, the related building moneys such as cement have 2 tons of use train transports nearly, and these crucial goods and materials total over 20 tons, occupy 3/4ths of China Railway.These service objects, against China railways system, also react on rail facility simultaneously, make it more improve with facility flourishing.In addition, China's power system also be unable to do without colliery.Every year, cause because of these resources cannot be transported timely and effectively national electric power system nervous, cause the event of heavy economic losses to happen occasionally.Much more as far as possible how must improve conevying efficiency, to increase national delivery, realizing China's rapid industrial development has become the important evidence that the railway system upgrades upgrading.As can be seen here, the railway system is as the foundation stone of China's economic base, and its importance is obvious to all.
But because NORTHWEST CHINA portion is subject to the impact of the correlative factor such as weather and environment, wind erosion problem in traffic route receives increasing concern day by day.Expand the planning of western road network coverage rate according to China's Eleventh Five-Year Plan, nearly 20 newly built railway sections in wind erosion district, transport development construction comes into one's own on the problem that affects of engineering day by day on Effects of Soil Wind Erosion and wind erosion.Even so, in the area that dust storm is serious, late, the time delay of train is also often caused even to turn on one's side.
The harm of dust storm to railway is also subject to people's attention day by day.Dust storm one side heap sum hinders railway equipment to be made outside its cisco unity malfunction, these railway infrastructure of wearing and tearing year in year out on the other hand.Add the danger that the train was derailed, cause major traffic accidents, cause jogging or stop transport.Many troubles are brought to the normal operation of railway.
Railway transportation ensures that national economy can stablize the basic of sustainable development.The west area of China comprises the ground such as Shaanxi, Gansu, the Inner Mongol, Yunnan, Tibet by the area that sandstorm is comparatively serious.Wherein the Qinghai-Tibet Railway is by the comparatively serious section of railway track main line of sandstorm, is in the impact of the composite factor such as aggravation, excessive and random lumbering of severe cold areas and mankind's activity due to the ecological environment frailty in Qinghai-Tibet own and physical features.The segment section of Qinghai-Tibet Railway is buried rail due to dust storm and is caused 3452 shipping derails, and 125m circuit is ruined, and the time of cutting off traffic reaches more than 25 hour.Qinghai-Tibet Railway causes withdrawal of train 34 times due to dust storm buried line very many years ago.
No matter be domestic and international, various large-scale sand eliminator all be unable to do without Automated condtrol.The raising of human life quality is depend on the generation of automatic technology in human historical development and develop rapidly with developing very major part.So not only reduce relevant staff's quantity and corresponding working strength, bring innovation and the distillation of production technology and quality simultaneously.For this reason, the automation realizing sand eliminator has very important significance.Along with the raising of social Mechanization Technique level and the development of modernized railway Maintenance Machinery, develop a kind of efficient, energy-conservation, that automaticity is higher sand elimination machine and replace traditional artificial or small-sized sand eliminator to have profound significance and engineering practical value to remove railway sand.
Summary of the invention
