Description

Conveyor belt type two-way desanding and desanding device

technical field

The invention relates to the technical field of track sand cleaning, in particular to a belt-type two-way sand removal device for a road-rail dual-purpose track sand removal vehicle.

Background technique

Due to the impact of climate and environmental factors in Northwest my country, wind erosion of traffic lines has attracted more and more attention. According to my country's plan to expand the coverage of the western road network, there are about 20 newly-built railway sections in the wind erosion area, and the impact of traffic construction on soil wind erosion and the impact of wind erosion on engineering have been paid more and more attention. 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.
