Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of expanding and contracting so as to intersect a railroad track in a substantially orthogonal direction in order to move the workvehicle from the storage location of the workrail provided on the side of the railroad track to the railroad track. The present invention relates to a rail device provided in.

[0002]

2. Description of the Related Art Conventionally, as a telescopic rail device for railway work vehicles, a manual type is known. This is a type in which a worker manually pulls out a movable rail placed on a base rail fixed to a storage location of a work vehicle to extend the rail to a predetermined position when necessary. The storage location of the work vehicle may be provided on either side of the up train line or the down train line, and may be provided on each side of the up train line and the down train line. In either case, the telescopic rail device is provided for moving the work vehicle onto the ascending train line or the descending train line.

[0003]

When the storage location of the work vehicle is provided on either side of the up train track or the down train track, the vehicle on which the work is completed has been completed on the track on the side without the storage location. Must be moved to the intersection of the upper and lower tracks, the work vehicle must be moved to the track on the side where the storage is located, and then to the storage. When the storage place of the work vehicle is provided on each side of the ascending train track and the descending train track, many storage site sites and facilities are required.

Therefore, according to the present invention, even when the storage place is provided on either side of the up train line or the down train line, the work vehicle is transferred from the storage place to both the up train line and the down train line. An object of the present invention is to provide a relatively small-sized telescopic rail device capable of moving a rail.

In the present invention, in order to solve the above-mentioned problems, a base rail 1 is provided on a base B, and the base rail 1 is installed on a storage place P of a work vehicle C from its original position to a railway line R1. A base rail moving means such as a motor M1 and a chain 6 for making the base rail 1 reciprocate in the axial direction is provided while being movable to an advance position extending upward, and the movable rail 2 is used as a base. It is provided so that it can be placed on the rail 1, and this is the basic rail 1
A motor that allows the movable rail 2 to reciprocate in the axial direction while allowing the movable rail 2 to move from the original position in the axial direction to a forward position in which the tip of the base rail 1 is continuously extended onto the railroad tracks R1 and R2. M2 and a movable rail moving means such as a chain 8 are provided, and an auxiliary rail 3 is further provided on the base B, and the auxiliary rail 3 is continuously connected to the base rail 1 at the forward position from the original position located on the side of the base rail 1. To the forward movement position, which is movable in the direction orthogonal to the axis, an auxiliary rail moving means such as a hydraulic device 4 for reciprocating the auxiliary rail 3 is provided to construct a telescopic rail device for a railway work vehicle.

[0006]

The telescopic rail device for a railway work vehicle of the present invention is in a contracted state when not in use so as not to obstruct a train passing over the railroad tracks R1 and R2. In this state, the base rail 1 is in the original position retracted from the lines R1 and R2, and the movable rail 2 is in the original position where the movable rail 2 is overlaid on the base rail 1. The work vehicle C is stored with the traverse wheels W placed on the movable rails. In order to move the work vehicle C onto the nearer track R1, the vehicle C is first lifted by the attached lift device, and then the movable rail 2 is moved.
The movable rail 2 on the base rail 1 is moved in the axial direction by the movable rail moving means such as the motor M2 and the chain 8 in a state where it is free, and is lowered onto the base B to be continuous with the tip of the base rail 1. . With this, the movable rail 2
Extends on the nearer line R1 so as to intersect with it. Next, the vehicle body of the work vehicle C is lowered, the traverse wheels W are lowered onto the basic rail 1, and the rolling wheels W are rolled with the basic rail 1 and the movable rail 2 and moved onto the track R1. Here, the vehicle body is lifted again, the movable rail 2 is returned, and then the vehicle body is lowered to lower the traveling wheels onto the track R1. Then, the work vehicle C moves on the railroad track R1 to a predetermined work place. When the work vehicle C is returned to the storage location P, the work is performed in the opposite procedure.

In order to move the work vehicle C to the distant track R2, after extending the movable rail 2 by the above procedure, the basic rail moving means such as the motor M1 and the chain 6 moves the basic rail 1. Move both rails 2 forward.
With this, the base rail 1 extends so as to intersect the nearer line R1 and the movable rail 2 at the farther line R2 so as to intersect with each other. In this state, since there is an empty space on the base end side of the base rail 1, the drive device such as the hydraulic device 4 is operated to move the auxiliary rail 3 forward so that the base rail 1 is continued to the base end side. In this state, the vehicle body of the work vehicle C is lowered, the traverse wheels W are lowered onto the auxiliary rails 3, and the auxiliary rails 3, the foundation rails 1, and the movable rails 2 are used.
Roll it and move it to the top of the track R2. Then, the work vehicle C is arranged on the track R2 in the same procedure as described above, and is returned to the storage location in the reverse procedure.

(A), FIG. 2 (A), and FIG. 3). In the contracted state, the movable rail 2 is laid on the base rail 1. In this state, the work vehicle C is in the storage location P,
Wheels W for traverse are placed on the movable rail 2 and stored. When the work vehicle C is used, first, the vehicle C is lifted by an attached lift device (not shown), and the movable rail 2 is freed, and the chain 8 is pulled around by the motor M2. Since the chain 8 is connected to the movable rail 2 via the pin 9 and the elongated hole 10, the movable rail 2 moves on the base rail 1 in the axial direction and extends so as to intersect with the railroad track R1.
