Sand suction method in non-central track bed area

Abstract

A method for sucking sand in a non-central ballast bed area, which includes: a. walking the sand suction operation vehicle to the road section to be operated, installing a hand-held suction pipe in the 0-3m work area according to the scope of the required operation, and placing the long boom and the short boom Above the non-central ballast bed area; b. The operator enters the non-central ballast bed area that needs to be operated, and the operator in the 0‑3m non-central ballast bed area controls the hand-held straw to make it in place through the handle; f. The operator controls the hand-held straw to make it in place position; g. Turn on the cyclone dust collector, and the operator in the 0-3m operation area controls the hand-held suction pipe and the hand-held suction pipe to sweep over the track bed in sequence, so that the sand in this area is sucked up. It adopts a sand suction working device, which uses a combination of two suction ports, and cooperates with two sets of suction pipes with different lengths to achieve long and short distance sand suction without dead ends, and has high sand suction efficiency.

Description

technical field [0001] The invention relates to a sand suction method for a non-central ballast bed area, in particular to a sand suction method suitable for high-speed railway lines, and belongs to the technical field of railway maintenance machinery. Background technique [0002] The sand suction operation in the non-central ballast bed area is one of the main tasks in the mechanized maintenance of railway lines. The high-speed rail line will inevitably be built in areas with frequent sandstorms. The sand on the high-speed rail line and nearby areas has accumulated seriously for a long time, which affects the driving safety of the line. The cross-section of the ballast bed in the central ballast bed area is very regular, and a good sand removal effect can be achieved by using conventional sand removal machines. However, the non-central ballast bed area of ​​the line refers to the area where the radius from the guardrail to the ballast bed of the high-speed railway line is ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to remove the sand in the non-central ballast bed area of ​​the high-speed railway line, and eliminate the hidden danger of the residual sand to the driving safety.
