Description

Continuous sleeper-changing operation train

Technical Field

The application relates to the field of railway engineering operation, in particular to a continuous sleeper-changing operation train.

Background

The railway sleeper replacement is one of the main works in the mechanical maintenance of railway lines. Along with the continuous development of engineering technology, the pillow changing work is changed from the traditional full-manual operation into the operation of small-sized machinery and large-sized road maintenance machinery, the pillow changing time is shortened, the labor intensity of constructors is reduced, the personnel allocation is reduced, and the management is convenient.

At present, there are two main methods for replacing pillows by small machines: firstly, a sleeper is laterally moved out from a line by adopting small machinery matched with rail lifting equipment, and is laterally replaced in a side-pulling manner; and secondly, constructing by matching a highway and railway dual-purpose excavator with a sleeper clamp. In both schemes, a new sleeper needs to be transported to the two sides of a track of a sleeper to be replaced in advance and distributed, and an old sleeper placed on the two sides of the track needs to be transported away after replacement is finished, so that the two sides of the track need to occupy larger space on one hand, and the two sides of the track need to be transported for multiple times on the other hand; and need the manual work to go up the fastener after the sleeper is changed and is accomplished, need a large amount of manual work cooperations, the loaded down with trivial details and efficiency of step is lower. In addition, the railway sleeper replacement in the prior art does not generally treat a sleeper bottom track bed, and the construction quality is not high; therefore, the step of treating the sleeper track bed is needed subsequently, so that the number of processes is large, the continuity is poor, the duration of the whole sleeper replacement process is long, and the normal operation of the railway is greatly influenced.

The sleeper replacement by adopting a large road maintenance machine is carried out by adopting a mode of overhauling a train, the sleeper replacement of the train needs to cut off a track, the sleeper replacement and the track replacement are carried out at the same time, and the construction efficiency is lower. Because the track needs to be cut off during construction, the track needs to be welded to restore the track to a seamless track after construction is finished, and construction steps and maintenance cost are increased.

In view of this, the present application is specifically made.
