Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a trackbed changing machine transport vehicle for transporting a trackbed changing machine used for complete and partial railway bed changing to a work site.

(Prior art) In general, on railway trackbeds, the surfaces directly below the sleepers harden due to mud blowing caused by rail vibrations and other causes.
It begins to lose its elasticity. If the trackbed solidifies and loses its elasticity, not only will the ride comfort of the vehicle deteriorate, but there is also the risk of early track deviation.
Therefore, if consolidation occurs on a railway track bed, it is necessary to replace the track bed as soon as possible.

Up until now, most of the partial replacement of railway trackbeds has been done by input, but as it has become difficult to secure labor, some railways have replaced hydraulically driven crawler type replacements. A method of replacing the track bed using a track bed replacement machine (for example, a power shovel) has been introduced. That is, the track bed replacement machine is moved by itself on the track bed to the track bed replacement point, and a hydraulic excavator excavates and scoops out gravel to replace the track bed.

(Problem to be solved by the invention) However, in the above case, when the trackbed changing machine enters the track from the level crossing and moves on the trackbed, the rubber belt is attached to the trackbed in order to prevent the crawler running device from damaging the concrete sleepers. The system is being installed one after another up to the replacement point and driving on top of it. As a result, the progress speed of the bed changing machine becomes slow, and it takes time to move to the work site, resulting in a problem that workability becomes extremely poor.

Also, after the work is completed, the track bed changing machine must be moved off the railroad tracks from the level crossing one hour before the first train arrives.
In this case as well, since it had to run on a rubber belt, rapid movement was not possible.

Furthermore, even when rubber belts were laid, concrete sleepers were often damaged.

This invention was devised to solve the above-mentioned problems, and its purpose is to create a trackbed changing vehicle that can quickly and smoothly move a trackbed changing machine to a work site or from a work site to off-track. is to provide.
