Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rail replacement vehicle for renewing and replacing tracks or rails constituting an existing track of a railway vehicle.

[Conventional technology] To replace the rails that make up the track of a railway vehicle, new rails are loaded onto trolleys or special freight cars and transported to the site, and after the new rails are arranged in the predetermined positions, they are replaced by a rail replacement machine or a new rail replacement machine. This was done by deploying a mountain passer for rail replacement and calling in a large number of workers on another day.

In addition, in recent years, track structures such as rail welding technology and weighted sleepers have been developed, and more than 1 m of seamless rails are being replaced and laid every day. There is a method of welding around 200 m of rail transported to IKm and replacing this welded rail, and a method of replacing the welded rail.
There is a method in which rails in meters are once replaced and laid, and then welded. However, either method requires a large number of workers. In other words, the longer the rail to be transported or replaced, the more workers are required, and the transportation and replacement of the rail, the placement of equipment, the cleaning up of traces, etc., require dedicated transportation vehicles and replacement workers each time. equipment, etc. are used, but it is also carried out by a large number of workers.

In addition, the rail replacement equipment includes a rail replacement machine method that continuously replaces old and new rails from the end, and a small gantry crane (so-called Yamakoshi crane) that measures the entire length of the rail to be replaced. There is the Yamakoshi machine method, which lifts and moves the material all at once using a machine (machine), and then replaces it. The former rail replacement method requires a long time to replace the rails, but it has the characteristic that the number of workers can be reduced to about half of the number of workers in the Yamakoshi method, while the latter Yamakoshi method can perform replacement work in just a few minutes. However, the number of workers required is more than double that of the rail exchange system. However, both methods had problems.

[Problem to be solved by the invention]

Conventional rail replacement is carried out as described above, and because it assumes the presence of a large number of workers, there is a problem that it is not compatible with the current situation where only a small number of workers can be secured and the future. In other words, the conventional work method using equipment requires a large number of workers, but as the number of workers engaged in track maintenance work is gradually decreasing due to the aging of the population and changes in work motivation in recent years, it is no longer fully functional. I no longer do it. In reality, subdivision of the length of replacement rails is being considered in various places, and it has become almost impossible to replace long rails at once as was the case up until now. Furthermore, as it is predicted that it will become more difficult to secure a workforce in the future, there is an even greater need than ever for mechanization to significantly eliminate track maintenance work.

The present invention has been made in view of the above, and an object of the present invention is to provide a rail changing vehicle that can significantly omit and mechanize track maintenance work.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, a traveling platform is supported by a traveling platform movable in the gauge direction, and this traveling platform is equipped with a guide provided with outriggers on both sides. In addition to mounting a platform, an elevating body movable in the gauge direction is placed on this guide platform, and this elevating body is capable of vertically transporting the track or rail that constitutes the track on the opposing rotating body. It is characterized by the provision of a rail catch that allows it to be held in place.

[Effect]

According to the present invention, the traveling platform is supported by a traveling platform that is movable in the gauge direction, and a guide platform having outriggers on both sides is mounted on the traveling platform, and a guide platform is mounted on the guide platform in the gauge direction. A movable elevating body is placed on the
A rail catch is installed on the opposing rotating bodies to clamp the track or rail that makes up the track so that it can be moved vertically, so the rail can be transported by being suspended within or outside the track by a rail replacement vehicle. It's quiet. In addition, the old and new rails can be alternately lifted and moved laterally at the position where the new rail has been lowered, allowing the rail to be replaced or laid. In addition, the replaced old rail can be immediately hung up and transported home.

In addition, during preparatory work, new rails and a rail replacement vehicle may be placed outside the local construction limits, and the rail replacement vehicle may be moved onto the track at the same time as track closure begins. By using a rail replacement vehicle, rail replacement work can be carried out by a small number of people in a short period of time. Furthermore, it becomes possible to vertically feed the track or rail, and the position of the rail catch and the installation position of the vertically fed rail can be freely adjusted, especially in curved sections.

This has the effect of reducing the number of workers who previously required more than 10 Å to one person, as well as making it possible to complete the work reliably within the conventional working time. . Furthermore, by using a plurality of rail replacement vehicles, the entire process of replacement work, except for tightening and tightening the old and new rails, can be carried out automatically and continuously by a small number of people in a short period of time. The vertical feed roller, which is the rotating body of the rail catch, clamps the old and new rails so that they can be fed vertically in the track direction, making it possible to feed the rail vertically, making it especially easy to adjust the position of the rail catch and the installation position on curved sections. It has the effect of allowing you to do it freely.
