That is, the lift device 2 raises the traveling carriage 1 by extending the rod of the hydraulic cylinder 2a, and at the raised position,
This serves to freely change the direction of the traveling carriage 1.

In FIGS. 2a and 2b, what is composed of a mounting table portion arranged between the rails R and R and an inclined plate portion arranged on the side of the rails R and R is as follows: A travel switching auxiliary device 12 used when moving the traveling carriage 1 between the rails R and R and from the rails R and R to the outside of the rails R and R. It works smoothly. However, the travel switching auxiliary device 12 is not always necessary in the travel carriage 1 having the rubber crawler belt 1b that does not damage the rail R. This is because, for example, a sloped road is formed by a ballast ballast, a ballast ballast is laid between the rails R and R, and then removed after the work is completed. Further, in order to travel freely on the rails R, R outside the crawler belt 1b of the traveling carriage 1 and before and after in the traveling direction, the structure described later can be raised / lowered, that is, flipped up. A driven side rail traveling device 3 and a driving side rail traveling device 4 are provided respectively.

A driven wheel support shaft 3b, which has a square cross-section having a polygonal bracket 3c at its tip and is provided with locking grooves at two positions in the longitudinal direction, slides in the longitudinal direction from both openings of the rectangular tube 3a. The lock screw 3 is freely fitted and is provided in these lock grooves on the upper surface side of the rectangular tube 3a.
The tip of k is engaged.

A wheel support leg 3d, which is electrically insulated from the rails R and R and has a driven wheel 3e for rolling the rails R and R on the free end side, is swingable on each of the brackets 3c. As shown in FIG. 1, when the driven wheel 3e is rollingly contacted with the rails R and R, the wheel support leg 3d is fixed by the lock pin 3f at the position swinging downward, as shown in FIG. Further, even when the wheel support leg 3d is swung upward, the lock pin 3f is configured to maintain the same state. The driven wheel support shaft 3b
Is slidable, and is configured to be fixed by the lock screws 3k at the two lock groove positions, respectively, by adopting a configuration that can correspond to both narrow gauge and wide gauge,
The aim is to increase its versatility.

A wheel support leg 4 in which a power transmission mechanism 5 is internally provided and a tubular body 4b is horizontally mounted on the free end side.
a and 4a are provided. These wheel support legs 4a,
On opposite sides of 4a, the cylindrical body 4b is slidably fitted in the longitudinal direction, and the rails R, R are respectively provided on the protruding end sides.
A drive wheel support shaft 4c, to which a drive wheel 4d that is electrically insulated is fitted, is mounted. Although not shown, the wheel supporting legs 4a, 4a are held in a state of being swung downwards and in a state of being swung upwards so that the wheel supporting legs 3d of the driven side rail traveling device 3 are held. It is done by inserting and removing the lock pin in the same manner as in.

Next, the structure of the power transmission mechanism 5 provided in the wheel support legs 4a, 4a will be described. However, since the power transmission mechanism 5 has the same structure as the left and right hands, the structure of only one side will be described. The power transmission mechanism 5 drives the drive sprocket 1c as shown in FIG. An input shaft 5b rotated by a sprocket drive shaft 1g via a coupling 5a is fitted into a shaft hole of a large-diameter V belt pulley 5c supported by a wheel support leg 4a via a bearing B. . Further, the drive wheel support shaft 4c is disposed at a position distant from the input shaft 5b, and a spline is formed on the drive wheel support shaft 4c, which is attached to the wheel support leg 4a. It is slidably fitted into a shaft hole having a spline of a small-diameter V belt pulley 5d supported through a bearing B.

A V-belt 5e having a length that can be loosened is mounted on these V-belt pulleys 5c and 5d, and the transmission of power from the large-diameter V-belt pulley 5c to the small-diameter V-belt pulley 5d is as shown in FIG. 6, the belt tension roller 5f is pressed against the V belt 5e. When the traveling carriage 1 is driven by driving the crawler belts 1b and 1b, the belt tension roller 5f does not press the V belt 5e. It is configured to be released. In addition, a lock groove is circumferentially provided (only one place is shown) at two places on the side opposite to the drive wheel mounting side of the drive wheel support shaft 4c, and the tip of the lock screw 5g provided on the cylindrical body 4b is engaged. Drive wheels 4
By maintaining the spacing of d and 4d at the rail spacing,
Similar to the driven-side rail traveling device 3, the rail-side traveling device 3 is adapted to handle both narrow gauge and wide gauge.

By the way, the driven wheels 3e and the driving wheels 4d are electrically insulated from the rails R, R. The reason is that the operation of the traffic light is prevented by insulating the traveling carriage 1 from the rails R, R, and the occurrence of the abnormality of the traffic light due to the operation of the traveling carriage 1 in the non-steady state is prevented, so that the normal traveling of the vehicle is prevented. This is to prevent any trouble.

Further, as shown in FIG. 1, a fixed pole 6 having a structure described later is erected on one side in the width direction of the traveling carriage 1. The fixed pole 6 includes a base end side pillar 6a which is erected on the traveling carriage 1 and a base end side pillar 6a.
And a telescopic support column 6b which is slidably fitted from above and fixed with a lock pin 6c and an illumination lamp L is mounted. A crane beam 7 to be described later that reciprocally supports an electric winch 8 that is a suspension device that suspends a switch that operates by receiving electric power from an on-board generator.
One end side of the is pivotable about a vertical axis and is horizontally connected. Although the electric winch 8 is configured to be supplied with electric power from the generator mounted on the traveling vehicle 1, it is not necessary to mount the generator when electric power can be supplied from an external power source. Of course, during nighttime work, electric power is also supplied from the generator to the illumination lamp L. Further, in this example, the electric winch 8 is adopted, but a chain block may be used.

As shown in FIG. 7, the crane beam 7 includes a base end beam 7a attached to the tip end of the telescopic column 6b of the fixed pole 6 and a connecting pin 7c which can be inserted and removed on the opposite side. And a bendable joint beam 7b which is connected and has a bent portion 7d on the lower side at an intermediate position in the longitudinal direction, and the upper surface of the bent portion 7d is in contact with the bendable joint beam 7b to keep the straight state. On the side opposite to the connecting side of the additional beam 7b, a moving pole 9 having a configuration described later is formed.
Are connected to each other, and the crane beam 7 is supported thereby. In addition, the reason why the crane beam 7 is constructed as described above is in consideration of the manual loading and unloading.

The movable pole 9 is removably laid parallel to the rails R, R at an outer position on the side opposite to the fixed pole of the rail R on which the traveling carriage 1 travels, and has a groove-like rolling motion for rolling wheels. It is adapted to be moved along a guide rail 10 having a surface 10a. The moving pole 9 is provided with a trolley portion 9a having a plurality of wheels rolling on the rolling surface 10a of the guide rail 10 at a lower portion thereof, and a rectangular tubular base end erected on the trolley portion 9a. Side support 9b, telescopic support 9c slidably fitted from above the base end support 9b, and fixed by a lock pin 9e, and the height of the crane beam 7 provided on the top of the support support 9c. And a jack 9d for finely adjusting. By the way, the guide rail 10
In the case of rough terrain where it is difficult to install, the wheel portion of the moving pole 9 is removed, and this pole is erected instead of the fixed leg, so that at least loading and unloading of the switch can be performed.

The mode of use of the switching device exchange work system will now be described. A repaired switching device (not shown) is loaded on the loading platform 1a at the repairing factory, and the track R 1b is driven to drive the rail R, When the traveling carriage 1 is moved during R and the rod of the hydraulic cylinder 2a of the lift device 2 is extended downward between the rails R and R, the ground plate 2d is grounded and the traveling carriage 1 is lifted. Then, in the raised state, the main body is pushed to rotate the traveling carriage 1 so that the front-back direction of the traveling carriage 1 coincides with the rails R, R. Further, while the traveling carriage 1 is being raised, the driven wheel support shaft 3b and the drive wheel support shaft 4c are pushed and pulled to move the driven wheels 3e and 3e and the drive wheels 4d and 4d. Fit to width. Of course, since it is known before work whether the rail has a narrow gauge or a wide gauge, the distance between these wheels may be adjusted in advance.

Next, the driven wheels 3e, 3e and the drive wheel 4
The wheel supporting legs 3d and 4a of the driven-side rail traveling device 3 and the driving-side rail traveling device 4 are swung downward until they are in contact with the rails R and R, respectively. When the rod of the hydraulic cylinder 2a of the device 2 is contracted, the traveling carriage 1 can travel on the rails R and R by the driven wheels 3e and 3e and the driving wheels 4d and 4d. Then, the belt tension roller 5f causes the V-belt 5e.
By pressing to apply tension to the V-belt 5e and rotate the sprocket drive shaft 1g, the drive wheel support shaft 4c is rotated via the power transmission mechanism 5 and the drive wheels 4d, 4d roll. The traveling carriage 1 travels on rails R and R. Of course, if the V-belt 5e is not pressed by the belt tension roller 5f, the drive wheels 4d and 4d rotate freely, so that the traveling carriage 1 can be pushed and freely moved.

In this way, the traveling carriage 1 is caused to travel to a desired place, and at that position, the guide rail 1 is provided in parallel to the rails R, R at positions sandwiching the switch disposition position to be replaced.
0 is laid and the carriage 9a of the moving pole 9 is arranged on the guide rail 10. In parallel with this, while turning the direction of the base end beam 7a in a direction orthogonal to the front-rear direction of the traveling carriage 1, while connecting the beam 7b to the free end of the base end beam 7a by a connecting pin, Form the crane beam 7 by straightening the added beam 7b,
The tip of the additional beam 7b is connected to the top of the jack 9d of the moving pole 9.

Then, the jack 9d is rotated to finely adjust the height of the moving pole 9 so that the crane beam 7
Adjust so that it becomes horizontal. Of course, before making fine adjustments, the height of the fixed pole 6 can be adjusted by raising and lowering the telescopic column 6b.
The height of the moving pole 9 is roughly adjusted in advance by raising and lowering the telescopic column 9c. Therefore, by the assembly / adjustment work described above, the switch operating system is brought into a state as shown in FIG. 1, for example. Therefore, first, the repaired switch which has been loaded is suspended by the hook 8a of the electric winch 8 and is unloaded from the loading platform 1a to a position near the position where the switch to be replaced is arranged. In the empty state, it is moved to the position where the switch to be replaced is arranged, and here the switch to be replaced is hung by the hook 8a, loaded on the bed 1a, and then unloaded. The repaired switch is suspended, set at a predetermined position and mounted, and the switch is replaced.

In this way, when the switch has been replaced, the crane beam 7 is disassembled, the moving pole 9 is removed, the laid guide rail 10 is removed, and both of them are loaded on the loading platform 1a for a predetermined period. Self-propelled back to the position.
At a predetermined position, the rod of the hydraulic cylinder 2a of the lift device 2 is extended to raise the traveling carriage 1, and the wheel support leg 3d of the driven-side rail traveling device 3 and the wheel support leg 4a of the driving-side rail traveling device 4 are connected. Swing it up and secure with a lock pin. Then, if the traveling carriage 1 is turned by 90 degrees by manpower and the rod of the hydraulic cylinder 2a is contracted, the crawler belt 1b can travel. After that, track 1b
After returning to the factory by self-propelled vehicle, unloading the switch mounted on the loading platform 1a for repair, transporting the repaired switch, replacing the switch, and recovering the removed switch A series of work related to is completed.

Therefore, as described above, it is possible to easily transport a switch which has been repaired as described above, replace the switch, and recover the removed switch without the need to change the installation of the gate crane as in the conventional case. Since a series of operations relating to (1) can be performed, the conventional switch exchanging work requires 4 to 5 workers, whereas in the present embodiment, two workers are sufficient. In addition, since the switch, which is a heavy object, is suspended by the electric winch, the traveling carriage 1 is swung, the position of the wheel support legs 3d and 4a is adjusted, the crane beam 7 is disassembled and assembled, and the guide rail 10 is laid or removed. Light work such as loading and unloading the replenishment beam 7b, moving pole 9, guide rail 10 etc. can be done, and since there is no need to move the switch manually, the risk of switch operation is reduced. It has a great effect on labor saving, light work, and improvement of safety.

[0029]

As described in detail above, according to the switching device exchanging work system according to the first and second aspects of the present invention, the traveling carriage can travel both on the ground and on the rails. , The switch can be freely transported from the repair shop to the work site, and it is supported by the crane beam that is laid horizontally on the fixed pole that is erected on the traveling carriage and the movable pole that is movably supported. Since it is possible to suspend and move the switch from the loading and unloading work of the switch with the lifting device that is provided, the work of changing the installation of the gate-type crane, which was necessary in the past, is no longer necessary. Unlike conventional models, a small number of workers can easily and safely perform the work from transporting the switch to the replacement, saving labor and light work for the switch. Extremely effective in improving efficiency and safety
