Desand removal device for highway and railway dual-purpose track desanding vehicle

technical field

The invention relates to the technical field of special operation equipment for road and rail, in particular to a sand removal device for a road and rail rail desanding vehicle.

Background technique

Since the founding of the People's Republic of China, my country's railway system has been perfected and developed rapidly, and related transportation materials are also diverse. The distribution of goods ranging from coal, oil, and metals to timber, grain, and fertilizers is all undertaken by well-developed railway transportation without exception. Not only that, the prosperity and decline of these hundreds of industries related to railways are firmly controlled by my country's railway system. In addition, according to relevant statistics, nearly one billion tons of coal mines in my country choose to use train transportation, accounting for more than four-fifths of my country's total coal mines. More than 500 million tons of iron and steel industry choose to use train transportation. The oil industry has more than 100 million tons to choose train transportation. Nearly 70 million tons of agricultural, animal husbandry, chemical fertilizers and other materials are transported by train. Moreover, nearly 200 million tons of cement and other related construction materials are transported by train, and these key materials total more than 2 billion tons, accounting for three quarters of my country's railway transportation. These service objects rely on my country's railway system, and at the same time react to the railway facilities, making them more perfect, convenient and developed. In addition, my country's power system is also inseparable from coal mines. Every year, due to the inability to transport these resources in a timely and effective manner, the national power supply system is tense, causing major economic losses from time to time. How to improve transportation efficiency as much as possible, increase the national power supply, and realize the rapid development of my country's industry has become an important basis for the renewal and upgrading of the railway system. It can be seen that the importance of the railway system as the cornerstone of our country's economic foundation is obvious to all.

However, due to the impact of climate and environmental factors in the northwest of my country, the problem of wind erosion of traffic lines has attracted more and more attention. According to my country's "Eleventh Five-Year Plan" plan to expand the coverage of the western road network, there are about 20 new railway sections in the wind erosion area. Even so, in areas with severe wind and sand, it often causes delays, delays and even rollovers of trains.

The harm of wind and sand to the railway has also been paid more and more attention by people. On the one hand, the wind and sand accumulate and hinder the railway equipment so that it cannot work normally, on the other hand, it wears down these railway infrastructures for many years. Increased the risk of train derailment, causing major traffic accidents, resulting in delay or outage. It has brought many troubles to the normal operation of the railway.

Railway transportation is fundamental to ensure the stable and sustainable development of the national economy. In the western part of our country, the areas affected by wind and sand disasters are relatively serious, including Shaanxi, Gansu, Inner Mongolia, Yunnan, Tibet and other places. Among them, the Gela section of the Qinghai-Tibet Railway is a section of the main railway line that has been severely affected by wind and sand disasters. Due to the fragility of the ecological environment of Qinghai-Tibet itself, the terrain is in an alpine region, the intensification of human activities, and deforestation and other comprehensive factors. Some sections of the Qinghai-Tibet Railway caused 3,452 freight trains to derail due to the burial of rails by wind and sand, and the 125m line was damaged, and the interruption of travel time reached more than 25 hours. Many years ago, the Qinghai-Tibet Railway was shut down 34 times due to the burial of the line by wind and sand.

Whether at home or abroad, all kinds of large-scale sand removal equipment are inseparable from automatic control. The improvement and development of the quality of human life largely depends on the emergence and rapid development of automation technology in the course of human history. This not only reduces the number of related staff and the corresponding work intensity, but also brings innovation and sublimation of production technology and quality. For this reason, it is of great significance to realize the automation of sand removal equipment. With the improvement of social mechanization technology and the development of modern railway maintenance machinery, it is of far-reaching significance to develop a high-efficiency, energy-saving, and highly automated sand removal machine to replace traditional manual or small sand removal equipment to remove railway sand. Engineering practical value.
