Pendulum type accumulated sand cleaning device for railway roadbed in gobi gale area
The invention discloses a pendulum type accumulated sand cleaning device for a railroad bed in a gobi gale area. The pendulum type accumulated sand cleaning device comprises a sand blocking and guiding plate and a supporting mechanism. The sand blocking and guiding plate is connected to the supporting mechanism through a rotating shaft, the lower end of the sand blocking and guiding plate is a free end, and when the wind speed of the main wind direction is larger than a set value, the lower end of the sand blocking and guiding plate can rotate under the action of wind power, so that a first airflow channel is formed between the windward side of the sand blocking and guiding plate and the road shoulder of the roadbed; the first airflow channel is used for guiding airflow to a sand accumulation surface of a ballast bed and forming sweeping wind, and when the wind speed of the main wind direction is smaller than or equal to the set value, the lower end of the sand blocking and guiding plate makes contact with a road shoulder and is matched with the road shoulder to form a sand blocking wall structure. According to the pendulum type accumulated sand cleaning device for the railway roadbed in the gobi gale area, the double functions of the sand blocking wall and the sand guiding plate are integrated, the angle of the sand blocking and guiding plate can be automatically adjusted under different wind speed conditions, and accumulated sand is automatically cleaned and quicksand is blocked in time.
本发明揭示了一种用于戈壁大风区铁路路基的钟摆式积沙清理装置，包括阻沙导沙板和支撑机构；所述阻沙导沙板通过旋转轴连接在支撑机构上，并且所述阻沙导沙板下端为自由端，在主风向的风速大于一设定值时，所述阻沙导沙板下端能够在风力作用下旋转，使所述阻沙导沙板的迎风面与路基的路肩之间形成第一气流通道，所述第一气流通道用于将气流导向道床的积沙面并形成清扫风，在主风向的风速小于或等于所述设定值时，所述阻沙导沙板下端与路肩接触并配合形成阻沙墙结构。本发明用于戈壁大风区铁路路基的钟摆式积沙清理装置，集中了阻沙墙和导沙板的双重功能，可以在不同风速状况下，自动调整阻沙导沙板角度，适时自动清理积沙和阻截流沙。
