The description will be made with reference to FIG. 6 of the drawings, FIG. 7 of the crane beam connection state explanatory diagram, and FIG. 8 of the emergency drive device configuration explanatory diagram.

That is, reference numeral 1 shown in FIG. 1 is a traveling carriage on which an electric generator (not shown) is mounted and which runs on an engine. The traveling carriage has a loading platform 1a on the upper side and crawler belts 1b on both sides in the width direction. I have it. These crawler belts 1b, 1b are hung across a drive sprocket 1c provided on one side in the traveling direction, a driven sprocket 1d provided on the other side, and a plurality of idle rollers 1e provided therebetween. It is equipped. As described above, the traveling carriage 1 is of the crawler type because it is possible to travel on the ballast in the track bed without any trouble. In addition, what is erected at one end in the width direction on one side in the front-rear direction of the traveling carriage 1 is:
It is a control post 1f provided with a control lever or the like for controlling the traveling vehicle 1.

As shown in FIG. 2, a hydraulically operated lift device 2 for raising and lowering the traveling carriage 1 is provided between the lower crawler tracks 1b, 1b of the traveling carriage 1 as described below. There is. As shown in FIGS. 3a and 3b, the details of the lift device 2 are as follows: four hydraulic cylinders 2a whose rods extend and contract downwards, and lifting plates 2b which are pin-connected to the lower ends of the rods, The grounding plate 2d is rotatably mounted by a vertical swivel support pin 2c provided at the center of the plate 2b. 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 disposed between the rails R and R and an inclined plate portion disposed 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, the sloped road is formed by the ballast ballast, the 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.

First, in the driven-side rail traveling device 3, as shown in FIGS. 1, 4a and 4b, the rectangular tube 3a is horizontally arranged on the side opposite to the steering post of the traveling carriage 1, that is, in the front portion of the traveling carriage 1. Is stuck to. 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, extends from both openings of the rectangular tube 3a in the longitudinal direction. Is slidably fitted to the lock tube, and the lock groove is provided with a rectangular tube 3a.

Further, 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 rail R, the wheel support leg 3d is fixed by the lock pin 3f at the position of swinging downward. Even when 3d is swung upward, the lock pin 3f maintains the same state. The structure in which the driven wheel support shaft 3b is slidable and fixed by the lock screws 3k at the two locking groove positions is adapted to both narrow gauge and wide gauge. Therefore, the purpose is to increase its versatility.

Further, the wheel supporting leg 3d is provided with a conducting device 3g having a configuration described later. A case 3h is attached to the conduction device 3g so as to be orthogonal to the wheel support legs 3d, and the coil spring 3i is attached to the case 3h.
And a contactor 3j which is operated by being pushed by the elastic force of the coil spring 3i. That is, when the contactor 3j is rotated about the axis by a predetermined angle, the lock is released and the tip of the contactor 3j abuts on the inner surface of the driven wheel 3e. In this way, when the tip of the contactor 3j comes into contact with the inner side surface of the driven wheel 3e, the electrically insulated state between the traveling carriage 1 and the rails R, R is released, and the rails R, R with respect to the traffic signal are released. Since a signal indicating that there is a traveling vehicle is transmitted and becomes a red light, it is possible to prevent a collision accident or the like due to the entry of another vehicle.

As shown in FIGS. 1, 5 and 6, the drive-side rail traveling device 4 is swung around the extension shaft center of the sprocket drive shaft 1g for driving the drive sprocket 1c, and has a structure described later. 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 downward and in a state of being swung upward so that the wheel supporting legs 3d of the driven-side rail traveling device 3 are fixed. As with the method, it is performed by inserting and removing the lock pin.

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,
Explaining only the structure on one side, the power transmission mechanism 5
As shown in FIG. 5, a large diameter in which an input shaft 5b rotated by a sprocket drive shaft 1g for driving a drive sprocket 1c via a coupling 5a is supported by a wheel support leg 4a via a bearing B is shown. Is fitted in the shaft hole of the V belt pulley 5c. The drive wheel support shaft 4c is disposed at a position away from the input shaft 5b.
The drive wheel support shaft 4c is provided with a spline, which is slidable in a shaft hole having a spline of a small-diameter V belt pulley 5d supported by the wheel support leg 4a via a bearing B. It is fitted.

A V-belt 5e having a length that can be loosened is mounted on these V-belt pulleys 5c and 5d, and the power transmission 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. Further, a lock groove is circumferentially provided (only one position is shown) at two positions on the side opposite to the drive wheel mounting side of the drive wheel support shaft 4c, and a lock screw 5g which is a lock mechanism provided on the tubular body 4b is provided. By engaging the tips and maintaining the distance between the drive wheels 4d, 4d at the rail distance, as in the case of the driven-side rail travel device 3,
It is designed to be compatible with both narrow gauge and wide gauge.

By the way, as described above, the driven wheels 3e and the driving wheels 4d are electrically insulated from the rails R and R. The reason for this is to prevent the operation of the traffic signal by insulating the traveling vehicle 1 from the rails R, R, and to avoid the occurrence of an abnormality in the traffic signal due to the operation of the traveling vehicle 1 in an unsteady state.

Further, as shown in FIG. 1, a fixed pole 6 having a structure described later is provided upright on one side in the width direction of the traveling carriage 1. The fixed pole 6 is slidably fitted to a base end side pillar 6a of a rectangular tube shape which is erected on the traveling carriage 1 from the upper side of the base end side pillar 6a, and the lock pin 6 is provided.
It is composed of a telescopic column 6b fixed by c. At the tip of the telescopic column 6b, a switch which is operated by being supplied with electric power from a generator mounted on the traveling carriage 1 is suspended. A base end beam 7a, which constitutes a part of a crane beam 7 to be described later, which supports an electric winch 8 which is a suspension device so as to be reciprocally movable, is pivotable about a vertical axis and is horizontally connected. Although the electric winch 8 is used in this example, a chain block may be used.

As shown in FIG. 7, the crane beam 7 is connected to a base end beam 7a attached to the distal end of the telescopic support column 6b and a connecting pin 7c which can be attached to and detached from the opposite end of the extension beam 6b. Bent portion 7 on the lower side at the intermediate position in the direction
It is provided with a bendable joint beam 7b which is provided with d and whose straight state is held by abutting the upper facing surfaces of the bent portion 7d. The joint beam side of this joint beam 7b will be described later. The movable poles 9 to be configured are connected at their tips to support the crane beam 7. The crane beam 7 is assembled to facilitate the transportation by reducing the weight of each part.

The movable pole 9 is movably laid parallel to the rails R and R on the side opposite to the fixed poles of the rails R and R on which the traveling carriage 1 travels, and has a groove shape for rolling wheels. It is movably supported along a guide rail 10 having a rolling surface 10a. And this moving pole 9
A trolley portion 9a provided with a plurality of wheels rolling on the rolling surface 10a of the guide rail 10 at the lower portion, a base end side column 9b standing on the trolley portion 9a, and a base end side column 9b. Of the telescopic column 9c which is slidably fitted from above and fixed by a lock pin 9e, and a jack 9d which is provided on the top of the telescopic column 9c and finely adjusts the height of the crane beam 7. It has become. In the case of rough terrain where it is difficult to install the guide rail 10, the wheel switch can be unloaded by removing the wheel portion of the moving pole 9 and replacing it with a fixed leg.

The traveling vehicle 1 is provided with an emergency drive device which is a self-propelled means for self-propelling the traveling vehicle 1 in the event of an emergency such as running out of fuel or engine trouble. As shown in FIG. 8, this emergency drive device 11 outputs the output shaft 1 of a transmission that transmits the drive force of the engine to the sprocket drive shaft 1g of the traveling vehicle 1 via a drive pulley 1i that is a power transmission unit.
A pulley 11b equipped with a one-way type clutch 11a mounted on h, a motor 11c mounted on the lower portion of the traveling truck 1 on the side of the control post 1f, and driven by being supplied with electric power from a battery (not shown), and this motor It is composed of a V belt 11d which is a motor power transmission member for transmitting the driving force of 11c to the pulley 11b.

That is, when the traveling vehicle 1 is driven by the engine, the pulley 11 is engaged even if the clutch 11a is disengaged and the transmission output shaft 1h is rotated.
b is not rotated, but the transmission output shaft 1h
Is transmitted to the drive wheel 4d via the output shaft 1h of the transmission, the drive pulley 1i, and the sprocket drive shaft 1g. When the engine cannot run due to some trouble, the clutch 11a is engaged and the motor 1
The rotation of 1c is transmitted to the drive wheel 4d via the pulley 11b, the drive pulley 1i, and the sprocket drive shaft 1g. In this case, a parking brake (not shown) that brakes the rotation of the output shaft 1h of the transmission
Is canceled.

The mode of use of the switching device exchanging vehicle having the above structure will be described below. A repaired switching device (not shown) is loaded on the loading platform 1a at the repair factory and driven by the crawler belt 1b to drive itself. The traveling carriage 1 is moved between the rails R and R, and the hydraulic cylinder 2a of the lift device 2 is moved between the rails R and R.
When the rod is extended downward, the ground plate 2d comes into contact with the ground and the traveling carriage 1 is raised. Then, in the raised state, the main body is pushed to rotate the traveling carriage 1 so that the front-rear 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 so that the distance between the driven wheels 3e and 3e and the drive wheel 4d,
The width of each of the traveling rails R and R is adjusted to the interval of 4d. 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 reduced, the traveling carriage 1 is allowed to travel on the rails R, R by the driven wheels 3e, 3e and the driving wheels 4d, 4d. When the belt tension roller 5f presses the V belt 5e to apply tension to the V belt 5e and rotates the sprocket drive shaft 1g, the drive wheel support shaft 4c is rotated via the power transmission mechanism 5, Since the drive wheels 4d roll, the traveling carriage 1 travels on the rails R, 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 moved.

Then, the traveling carriage 1 is caused to travel to a desired place, and at that position, guide rails 10 are laid parallel to the rails R, R at positions sandwiching the switch disposition position to be replaced. The carriage 9a of the moving pole 9 is arranged on the guide rail 10. In parallel with this, the proximal beam 7a
Is rotated in a direction orthogonal to the front-rear direction of the traveling carriage 1, while the joint beam 7b is connected to the free end of the base end beam 7a by a connecting pin 7c, and the joint beam 7b is straightened. The crane beam 7 is formed, and the tip of the additional beam 7b is connected to the top of the jack 9d of the moving pole 9.

Next, by rotating the jack 9d and finely adjusting the height of the moving pole 9, 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 above-mentioned assembly / adjustment work, the switchboard exchanging work vehicle is brought into a state as shown in FIG. 1, for example. Therefore, first, replace the loaded switch with the repair by the hook 8 of the electric winch 8.
It is hung by a and is unloaded from the loading platform 1a in the vicinity of 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 switching device has been replaced, the crane beam 7 is disassembled, the moving pole 9 is removed, the laid guide rail 10 is removed, and both are loaded on the loading platform 1a to a predetermined position. 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, when the traveling carriage 1 is swung 90 degrees by pushing manually and the rod of the hydraulic cylinder 2a is contracted, the crawler belt 1b can travel. After that, by returning to the factory by self-propelled by the crawler 1b and unloading the switch on the loading platform 1a for repair, the repaired switch was transported, the switch was replaced, and the switch was removed. A series of work related to the recovery of the switch is completed.

As described above, it is easy to carry the repaired switch, replace the switch, and recover the removed switch without the need to change the installation of the gate crane. Since a series of work can be performed, it is 4
Although ~ 5 workers were required, two workers were sufficient in this embodiment. In addition, since the switch, which is a heavy load, 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.

During such a switching operation of the switch,
For example, there is a possibility that the traveling vehicle 1 cannot run on its own due to lack of fuel, engine trouble, or the like. As is well understood from the above description, if the pressing force of the V-belt 5e by the belt tension roller 5f is released, the traveling carriage 1 can be pushed and moved. However, when the switch 1 is loaded on the loading platform 1a and it is necessary to move it for a long distance, it is extremely difficult and dangerous to move the traveling vehicle 1 by pushing it. Therefore, the emergency drive device 11 and the conduction device 3g are activated.

Therefore, according to the emergency drive device 11, by engaging the clutch 11a and supplying electric power from the battery to the motor 11b, the drive wheels 4d are driven via the sprocket drive shaft 1g and the power transmission mechanism 5. The traveling vehicle 1 can be self-propelled and can be quickly moved by power. Furthermore, according to the conduction device 3g, when the contactor 3j is rotated about the axis to release the lock, the coil spring 3
The tip of the contactor 3j comes into contact with the side surface of the driven wheel 3e by the elastic force of i, so that the traveling carriage 1 and the rails R, R are brought into conduction, and the signal indicating that the traveling carriage 1 is on the rails R, R. Will be sent to the traffic light, and the blinking red signal will stop the entry of other vehicles. As described above, the switching device exchanging vehicle is provided with the emergency drive device 1 in order to ensure safety in an emergency.
Since the switch 1 and the conduction device 3g are provided, the switch operation can be safely performed.

[0040]

As described in detail above, according to the switching device exchanging work vehicle according to claims 1, 2, 3, and 4 of the present invention, the traveling carriage has both ground and wide / narrow gauge rails. Since it can be self-propelled, the switch can be freely transported from the repair shop to the work site, and it is supported by a crane beam that is laid horizontally between a fixed pole and a moving pole that are erected on the traveling carriage. 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. Moreover, since it is equipped with an emergency drive device and a continuity device, it does not require a large number of workers as in the conventional case, and a small number of workers can easily and safely perform the work from transport to replacement of the switch. Because it can be done, labor saving of switch operation and
It has an extremely great effect on light work and improvement of safety.
