Sewage suction port structure suitable for ballast beds at two sides of ballastless track steel rail of high-speed rail and sewage suction truck

Abstract

The invention relates to a sewage suction port structure suitable for ballast beds at two sides of a ballastless track steel rail of a high-speed rail and a sewage suction truck. The sewage suction port structure comprises an air pipe, an air outlet is formed in the upper end of the air pipe, an air suction port is formed in the lower end of the air pipe, the air outlet is configured to be communicated with an external negative pressure air source, and the air suction port is configured to suck sewage on the ballast beds through negative pressure; and the portion, provided with the air suctionport, of the lower end of the air pipe is a flexible suction pipe, the height of the flexible suction pipe is larger than that of a sleeper, and therefore the flexible suction pipe can be impacted bythe sleeper to deform and cross the sleeper. By means of the sewage suction port structure, the distance between the lower end of a sewage suction port and the ballast beds can be reduced, and dirt at the ballast beds can be conveniently removed.

Description

technical field [0001] The disclosure belongs to the technical field of sewage suction vehicles, and in particular relates to a sewage suction port structure suitable for ballastless track rails on both sides of high-speed railways and a sewage suction vehicle. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the vigorous development of high-speed railways, more and more high-speed railways are put into operation. For the safe operation of high-speed railways, it is necessary to grind the rails regularly. The rail grinding vehicles will produce a lot of iron powder and dust after grinding, and the grinding vehicles themselves are not enough to vacuum A lot of iron filings will be left behind. More dust poses a threat to the safety of rail vehicles, line signal displays, trackside equipment, public works maintenance and even high-speed rail. ...

AI Technical Summary

Problems solved by technology

[0004] The inventor has learned that the technical difficulty of developing a ballast-absorbing truck for collecting the iron filings on the ballastless track bed of high-speed rail lies in the outer track bed of the rail. Due to the existence of sleepers and fasteners, the dirt-absorbed surface is not flat. For the safety of the vehicle, the dirt-suction The distance between the mouth and the road bed surface is more than 300mm, the suction power will decrease rapidly, and the suction effect is difficult to guarantee
