Description

The present invention relates to a moving device for a railroad rail used for moving a short railroad rail.

Conventionally, when moving a railway rail of about 1 m to 2 m to a desired place, if the moving distance is relatively short and it takes time to arrange a small mobile crane, etc., it is lifted and moved by two workers. I tried to make it, but the railroad rail has a shape that is difficult to grasp, and even a short railroad rail of about 1 m to 2 m weighs about 50 kg to 120 kg, so drop it by any chance. In consideration of injury, I try to refrain from such work.

On the other hand, it is complicated to use heavy machinery such as a small mobile crane to move a railroad rail that is heavy enough to be lifted by two workers, so a short railroad rail can be easily used. A method of moving is being studied.
Then, as a technique for easily moving a heavy object, for example, a fork inserted into the front side of the lower part of the heavy object is rotated around the wheel as a fulcrum by operating a handle to lift the front side of the heavy object. There is known a heavy object lifting / moving device that rubs and moves a heavy object in a state where the front side is lifted (see, for example, Patent Document 1).

JP-A-2010-37062

However, the heavy object lifting / moving device of Patent Document 1 cannot be used for moving a railroad rail because it is difficult to support a railroad rail having a narrow width and an elongated shape in a stable posture.

An object of the present invention is to provide a moving device for a railroad rail capable of easily moving the railroad rail.

In order to achieve the above object, the present invention
A moving device for railroad rails used to move railroad rails placed on the ground.
A holder portion that holds the rail head on the end face side of the railroad rail, and
A frame portion rotatably attached to the holder portion via a horizontal axis orthogonal to the longitudinal direction of the railway rail, with a handle provided on one end side sandwiching the horizontal axis and wheels provided on the other end side. When,
With
The handle is separated from the railroad rail, the frame portion is rotated in a direction in which the wheel is close to the railroad rail, and the wheel that rolls in contact with the ground is closer to the railroad rail than the end face of the railroad rail. The holder portion is configured to be located above the original position when the position is closer to the center side.

With the holder portion of the railroad rail moving device having such a configuration holding the rail head of the railroad rail placed on the ground, the handle is separated from the railroad rail and the wheel is framed in a direction close to the railroad rail. When the portion is rotated, the wheels of the railroad rail moving device come into contact with the ground. Even after the wheels come into contact with the ground, if the frame portion is rotated so as to separate the handle from the railroad rail, the wheels that come into contact with the ground roll, and the rolled wheels come from the end face of the railroad rail. Will also enter to a position closer to the center side of the railroad rail.
As the wheels of the railroad rail moving device enter the center side of the railroad rail from the end face of the railroad rail, the holder portion rotatably attached to the frame portion is located above the original position. It is possible to lift the end of the railroad rail held by the holder from the ground.

In other words, if a pair of railroad rail moving devices are attached to both ends of the railroad rail and both ends of the railroad rail are lifted from the ground by the pair of railroad rail moving devices, the railroad rail is lifted and held from the ground. can do.
Then, by pulling the handle of one of the railroad rail moving devices and moving the railroad rail moving device having wheels, the railroad rail that is floated and held from the ground by a pair of railroad rail moving devices is held. It can be moved to the desired location.
In this way, by using a pair of moving equipment for railroad rails, the railroad rails can be easily moved without arranging heavy machinery such as a small mobile crane.

Also, preferably
The distance from the horizontal axis to the end of the handle is longer than the distance from the horizontal axis to the wheel.
If the distance from the horizontal axis that is the fulcrum to the end of the handle that is the force point is longer than the distance from the horizontal axis that is the fulcrum to the wheel that is the point of action in the moving equipment for railway rails, use the "lever principle". The end of the railroad rail can be lifted from the ground with less force.

Also, preferably
The wheel is a free wheel that can turn the axle of the wheel.
If the wheels of the railroad rail moving device are free wheels, it becomes easy to move the railroad rail moving device in a desired direction.

Also, preferably
The holder portion is provided with an engaging means for anchoring the railroad rail.
If the railroad rail is fastened to the holder portion by the fastening means, the railroad rail is less likely to come off from the holder portion while the railroad rail is moving, so that the railroad rail can be suitably carried to a desired location.

Also, preferably
The frame portion is provided with a handle portion for carrying the railroad rail moving device.
If the railroad rail moving device is attached to a railroad rail having a shape that is difficult to grasp, the railroad rail can be easily lifted by grasping the grip portion thereof, so that the railroad rail can be carried to a desired place.

According to the present invention, the railroad rail can be easily moved.

By rotating the frame portion 30 in this way, the wheels 50 of the railroad rail moving device 100 come into contact with the ground G.

Then, even after the wheel 50 abuts on the ground G, when the frame portion 30 is rotated so as to separate the handle 40 from the railroad rail R, the wheel 50 abutting on the ground G rolls and rolls. The wheel 50 enters to a position closer to the center side of the railway rail R than the end surface of the railway rail R (see FIG. 3).
Further, at this time, if the worker puts his / her foot on the handle portion 34 and pushes it toward the railway rail R side, the wheel 50 is easily rolled, and the wheel 50 is easily moved toward the center side of the railway rail R. Become.

Then, as shown in FIG. 3, as the wheel 50 of the railroad rail moving device 100 enters the center side of the railroad rail R with respect to the end surface of the railroad rail R, the holder portion 10 connected to the frame portion 30 is formed. Since it is raised so as to be located above the original position, the end portion of the railroad rail R held by the holder portion 10 can be lifted from the ground G.
In particular, since the distance from the horizontal axis 20 as the fulcrum to the grip 41 of the handle 40 as the force point is longer than the distance from the horizontal axis 20 as the fulcrum to the wheel 50 as the point of action in the moving device 100 for railway rails. , It is possible to lift the end of the railroad rail R from the ground G with a small force by using the "lever principle".
