Trailer type sand elimination machine for railway

Abstract

The invention discloses a trailer type sand elimination machine for a railway, which comprises a lift hydraulic cylinder (1), a sand collecting and scraping device (2), a bidirectional sand blowing mechanism (3), a sand blowing transmission mechanism (4), a hydraulic system (5) and a vehicle body (6). When being used, the trailer type sand elimination machine is dragged to a working place by a locomotive, the sand collecting and scraping device (2) is descended to a working position by the control of the lift hydraulic cylinder (1), and the sand blowing transmission mechanism (4), a sand blowing belt (33) and a sand scraping mechanism (22) are sequentially started; and the trailer type sand elimination machine runs forwards with the dragging of the locomotive, a sand collecting box (21) is used for stacking accumulated sand at the middle and at the two sides of a steel rail to a certain height, a hydraulic motor (222) of the sand scraping mechanism is used for driving a drive chain wheel shaft to rotate, a scraper (229) is used for scraping the accumulated sand to a hopper (216), and the accumulated sand falls onto the sand blowing belt (33) and are blown out from the left side or the right side of the steel rail by the positive rotation or reverse rotation of a hydraulic motor (37) of the snow blowing mechanism. The trailer type sand elimination machine is simple in structure and high in automation, and is convenient to operate and easy to promote.

Description

technical field [0001] The invention belongs to railway track maintenance machinery, which is used for emergency dredging of buried railways in windy and sandy areas. It is trailer-type and does not need to be driven independently. It is used with locomotive hooks during work. The sand accumulation in the middle and both sides of the rails is automatically removed through the hydraulic system and control system. . Background technique [0002] At present, the emergency desanding methods of my country's main railway lines mainly use tools such as loaders, bulldozers and artificial shovels to clean up the accumulated sand. The environment is harsh and the work efficiency is low. Efficient special railway desanding machinery is still blank in my country. In recent years, some small special equipment for sand removal have also begun to appear. At an international railway equipment exhibition held in Beijing, several new types of equipment with snow and sand removal and blowing f...

Problems solved by technology

The railway desanding machine proposed in another document "Research on a New Type of Railway Desanding Machine" by the applicant of this patent is a completely independent engineering vehicle that needs to be driven by itself. The desanding function requires shoveling, The three-level device for sand transmission and sand blowing. The sand blowing device needs a hydraulic steering mechanism to realize left and right swing. The whole vehicle needs to be driven by a diesel engine, and a special cab and driving power transmission system are required. The disadvantage is that the maintenance of the sand blowing steering mechanism is difficult, and the volume of the whole vehicle big, expensive
