Ballast blowing device and method for ballast bed

Abstract

The invention provides a ballast blowing device and method for a ballast bed, which can realize high-efficiency blowing. The ballast blowing device of the ballast bed includes: a base part; two collecting boxes, respectively corresponding to the two bases, for holding the ballast to be replenished; two mounting frames, corresponding to the two collecting boxes, respectively The collecting boxes are erected on two bases respectively; two ballast blowing pipes are respectively connected with the outlets of the two collecting boxes, each ballast blowing pipe includes: The material guide tube extending downwards, the air guide tube connected with the air inlet located on the upper part of the material guide tube, is rotatably sleeved outside the main body section of the material guide tube, extends downward, and is provided with a guide tube on the bottom side wall. The outer casing of the ballast outlet connected to the outlet of the material pipe is connected with the outer casing, and the rotation angle of the outer casing is adjusted to adjust the direction of the ballast outlet; and two lifting mechanisms correspond to the two ballast blowing pipes respectively .

Description

technical field [0001] The invention belongs to the technical field of railway track maintenance, and in particular relates to a ballast blowing device and method for a ballast bed. Background technique [0002] After the railway has been in operation for a period of time, the ballast bed needs to be maintained. The most common maintenance methods include ballast tamping and ballast cleaning. Among them, tamping operation is the most common, but tamping operation has more and more obvious "memory effect", and it is difficult to cure it. The root cause of the so-called "memory effect" is that the ballast is broken into powder during the ballast tamping process, and the tamping operation cannot introduce additional ballast to make up for it, so the ballast bed is difficult to return to the pre-maintenance position under repeated train loads and tamping operations . [0003] Early researchers found that laying an extra layer of ballast material on the bottom of the sleeper ca...

AI Technical Summary

Problems solved by technology

At present, tamping equipment used in railways has been widely used, but there are few related ballast blowing equipment on the market, and there is no effective ballast blowing equipment for X-type sleepers at home and abroad. There are many problems such as blowing in, blocked pipes, and insufficient filling volume. There are a large number of unfilled areas at the bottom of the sleeper, and the efficiency of ballast blowing is much lower than that of tamping, which leads to high costs. Therefore, although the maintenance effect of ballast blowing is better than tamping in theory Good, but these problems in the actual ballast blowing operation prevent it from being widely used
