Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway rail exchanging device and an exchanging method suitable for exchanging an existing rail with a new rail due to aging or damage.

[0002]

2. Description of the Related Art In a railway in which rails are laid on a roadbed, when replacing existing rails with new rails, conventionally, a new rail is provided on a roadbed outside the existing rails in a direction substantially parallel to the existing rails. Temporarily put, set the state that the gantry frame type crane Yamagoshiki straddled the existing rail, and after removing the existing rail with this yamagoshi,
The method of moving the new rail to the position where the existing rail was laid was adopted. However, with such a method, when replacing a long rail having a rail length of 500 meters or more, a large number of Yamakoshi are required, which requires a great deal of cost and labor, and the operation of these many Yamakoshi is required. It was difficult to replace the rails by matching them. Further, when replacing the rails laid on the elevated structure, it is necessary to lift up a large number of the Yamakoshi devices from the ground and carry them in, which is disadvantageous in that it takes time and labor.

Therefore, a rail replacement method and a rail replacement device disclosed in Japanese Patent Application Laid-Open No. 1-299901 have been proposed. This is to run the front guide device on the existing rail, guide the new rail temporarily placed outside the existing rail to the inner rail laying position, and run the subsequent guide device on this new rail. An existing rail is removed to the outside by a rear guide device.

[0004]

According to the replacement method using the above-described replacement device, the new rail can be smoothly moved in a series of operations by running the front and rear guide devices without the need for a large number of Yamagoshi devices. There is an effect that the laying of the existing rail and the removal of the existing rail can be performed at the same time. However, even in the case of using this exchange device, the Yamakoshi device is still required when supplying a new rail to the preceding guide device and supplying an existing rail to the subsequent guide device. Therefore, there still remains a problem that it takes time to carry in and operate the Yamakoshi device. Also,
Since the guide devices at the front and rear stages have different configurations from each other, it is necessary to determine these configurations and set them on the rail so that the order before and after is not mistaken.
Requires complicated work and precise management. Further, there is also a problem in that the overall weight of each of the front and rear guide devices is increased, which makes it difficult to transport them to the site.

The present invention has been made in view of the above circumstances, and by not requiring a Yamakoshi device, the labor therefor can be reduced, the usage and management of the exchange device can be simplified, and the transport device can be more easily transported. It is an object of the present invention to provide a rail rail replacement device and a rail replacement method using the same, which facilitates delivery to the site.

Then, the guide portions 4 on both sides are slid to the removal position outside the main line rail, and thereafter, the new rail introduction mechanism 32 of the preceding apparatus 1A grasps the new rail R2 and guides it to the guide roller 31 as described above. Similarly, the new rail introducing mechanism 32 of the subsequent device 1B guides the old rail R1 to the guide roller 31 of the subsequent device 1B. At this time, the scrubber 50 of the pre-stage device 1A
Is operated to peel off the pat adhering to the bottom surface of the old rail R1, and to smoothly introduce the old rail R1 into the guide roller 31.

[6] From this state, both the upstream device 1A and the downstream device 1B are advanced by self-propelled at an appropriate constant speed. Then, the new rail R2 is laid on the roadbed D by passing through the wheels 13a and 13b and the clamp roller 14 of the subsequent device 1B via the guide portion 4 of the preceding device 1A, and at the same time as the laying of the new rail R2, The old rail R1 passes through the wheels 13a and 13b of the preceding device 1A and the guide portion 4 of the subsequent device 1B via the clamp roller 14, thereby being removed on the roadbed D outside the newly laid new rail R2. To go. FIG. 1 shows such a state, in which the old rail R1 and the new rail R2 are connected to the front stage device 1.
A new rail R2 intersects the old rail R1 between A and the downstream device 1B. The newly laid new rail R2
To the sleepers M sequentially.

According to the method of exchanging the old and new rails by the two rail exchanging devices 1 as described in the above [1] to [6], the former device 1A moves on the old rail R1 and the latter device 1
The new rail R2 is newly laid by sequentially traveling on the new rail R2 led by the front device 1A, and the old rail R1 is removed on both sides of this new rail R2, and the old and new rails are replaced. Is smoothly performed by a series of operations. Then, in order to set the new rail R2 in the preceding apparatus 1A, the new rail introducing mechanism 3 of the guide portion 4 of the preceding apparatus 1A is used.
2 does not require a Yamagoshi device as in the prior art. In other words, the rail can be replaced without using any Yamagoshi equipment, which is always necessary in the related art. Therefore, it is possible to solve the problem that it takes time to carry the Yamagoshi equipment to the site and to operate it.

Further, two rail exchanging devices 1 having the same structure are used.
It suffices to set one of them as the front-stage device 1A and the other as the rear-stage device 1B by using, and it is possible to save the trouble of deciding different configurations and setting them on the rail so as not to make a mistake in the front-back order. That is, the complexity of setting the rail exchanging device 1 is eliminated and the management of the rail exchanging device 1 is simplified.

Further, the rail exchanging device 1 includes a bogie unit 2
And a frame 3 mounted on the cart 2
And guide portions 4 attached to both ends of the frame portion 3
And the traveling drive unit 5, that is, they can be divided and transported individually. If the individual components are divided and transported one by one as described above, the components are reduced in weight and easily transported, and can be easily transported to the site without using a large-scale transport device.
