Description

[Apparatus to unload rails]

The present invention relates to a rail rail lifting device used for raising a replacement rail to a ground in a railroad car loaded with a rail during a rail replacement operation in which an existing rail and an exchange rail are exchanged during maintenance work on a railway track.

In general, a trailer for a railway track, which is capable of transporting a replacement rail, is provided with a car body to which the replacement rail is to be shipped, and a wheel for the railway which is provided on the car body and is mounted on the railway. The vehicle body is generally flat and arranged at a relatively low height on the ground to facilitate loading and unloading the replacement rail.

In the process of transporting the replacement rail to replace the existing rail in the railway track, the replacement rail is loaded on the trailer for the railway track and the rail is used to transport the rail to the destination. Then, the operator uses the lever to move the replacement rail to both sides .

At this time, the replacement rail mounted on the trailer falls to the ground, and is hit by the floor or the pedestal, thereby causing damage or generating a large noise. In addition, such a replacement rail requires a large amount of labor to work, resulting in poor workability and safety accidents.

In some cases, trailers for railway orbits on which replacement rails are loaded may need to be moved on public roads. However, conventional trailer trailers have a structure that can be moved only from a railway, and after the railway is used, There is a problem that the work cost and the cost are increased.

The third guide rail portion 17 includes a pair of guide portions 55 arranged in pairs and extending upward in the width direction of the second body 15.

The guide portion 55 extends upwardly and is provided with a groove passing through the guide portion 55 in the longitudinal direction of the rail R. [ These grooves serve to guide the rails R and can be inclined in the side direction of the second body 15 (in a direction inclined toward the railroad track on a plane basis).

The guide portion 55 is provided with a guide extension portion 57 extending from the guide portion 55 (see FIG. 5). It is preferable that the guide extension portion 57 is extended to the rear side of the second body 15 and is disposed downwardly inclined. The guide extension 57 is preferably longer than the rear end of the second body 1.

The guide extension 57 guides the end of the rail R to the ground when the rail R is lowered to prevent the rail R from being damaged by impact with the ground, .

A process of lowering the rail R mounted on a wagon using the rail rail lifting equipment of the embodiment of the present invention will be described as follows.

First, when the railway reclamation equipment moves on the land, the elevating and lowering portion 7 is adjusted so as to keep the road moving wheel 3 in contact with the road so that the rail moving wheel 5 is moved to the road moving wheel 3, Keep it higher on the ground.

That is, the connection hole 25a provided in the middle portion of the variable link 25 of the ascending and descending portion 7 is made to correspond to the connection hole 19a provided in the first link 19 and the connection pin 27 is connected to the connection hole 25a, and 19a. Then, the railroad moving wheel 5 is disposed at a position farther away from the ground than the road moving wheel 3, so that the railway raising and lowering equipment can be driven on the road.

These railway rail harnesses can be easily towed using trucks or SUVs.

In order to operate the railway raising equipment of the embodiment of the present invention in the railway, the connecting hole 25b provided at the end of the variable link 25 of the ascending and descending part 7 and the connecting hole 25b provided in the first link 19 19a, and the connection pin 27 is inserted into the connection holes 25b, 19a and fixed.

Then, the road-moving wheel 3 is disposed at a position farther away from the ground than the railway rolling wheel 5, and the railway railway warming equipment can travel on the railway.

In this manner, the railway railway reclamation equipment capable of traveling on a railway track is connected to a separate truck (not shown) carrying a replacement rail.

When the luggage car carrying the replacement rail moves along the railway, the railway rail lifting equipment of the embodiment of the present invention can move along the railway.

When the replacement rail reaches a place for lowering the replacement rail, the replacement rail can be installed on the side of the first guide rail part (9), the second guide rail part (11) and the third guide rail part To the rail portion 17 side. Then, the rail R is placed on the first guide rail part 9, and arranged so as to be fitted on the second guide rail part 11 and the third guide rail part 17. The rail R moves on the guide rollers 31 of the first guide rail portion 9 and at the same time is guided by the second guide rail portion 11 and the third guide rail portion 17, To the side of the rail rail harvesting equipment of the embodiment of the present invention).

As described above, according to the embodiment of the present invention, the rail R is smoothly moved along the guide roller 31 in the longitudinal direction, thereby reducing noise and preventing it from being damaged by colliding with the ground.

Particularly, since the guide extension portion 57 guides the end portion of the rail R to a position close to the ground, impact and noise can be remarkably reduced when the rail R is lowered.

In addition, since the embodiment of the present invention naturally raises the rail R without applying excessive force, it is possible to prevent a safety accident of the operator and increase the working efficiency.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
