DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a traverser for a rail car installed mainly in a railway tunnel such as a subway.

[0002]

2. Description of the Related Art As means for arranging railcars for work or track maintenance in a railway tunnel such as a subway, there are a means using a drop-in line and a means using a traverser. Of these, those that use drop-in lines are laid with a drop-in line extending from the track to branch off, and the connecting rail and main line rail are intermittently connected using a tent machine, so that the railroad car is connected to the drop-in line and the main line. It is intended to be replaced.

[0003] However, this requires a large space for laying the drop-in line, which not only increases the construction cost of the tunnel, but also causes the main rail to be cut off at the connection point with the drop-in line, which causes vibration of the vehicle. Problem. On the other hand, in the case of using a traverser, a rail car with a rail on which the rail car can run is installed so that it can move laterally from the evacuation area toward the main track, and the rail car is moved in the track. It is designed to be replaced with a main rail and a bogie. With this traverser, the evacuation area requires much less space than the drop-in type, so tunnel construction costs can be greatly reduced,
In addition, there is an advantage that it is not necessary to cut the rails of the track, which contributes to stable running of the vehicle.

[0004]

However, when the railcar is transferred to the main rail using the traverser in this way, the traverser staying at the evacuation area may move into the track for some reason when not in use. That would lead to a major accident. The present invention, in order to solve the problem
When providing locking means, the locking means may cause an accident.
Or drive with the trolley locked
The purpose is to prevent the user from doing so.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a state in which the traverser 1 is moved into the track L inside the tunnel, FIG. 2 is a side view taken along the line II-II of FIG. 1, FIG. 3 is a sectional view taken along the line III-III of FIG. 4A is a partially enlarged view of FIG. 1, FIG. 4B is a cross-sectional view of FIG. 4A taken along line BB, FIG. 5 is a cross-sectional view of FIG. 4 taken along line VV, and FIG. 7A is a cross-sectional view, and FIG. 7A shows VII in a state where the traverser 1 is parked outside the track L.
-VII sectional view, (B) is BB sectional view of (A),
(C) is a CC cross-sectional view of (A).

The traverser 1 is provided with a bogie 3 which moves on two moving rails 2 extending perpendicular to the main rail R on which the vehicle runs. As shown in FIG. 3, the moving rail 2 is divided at the location of the main rail R,
The moving rail 2 is set at a height higher than the main rail R so that the carriage 3 can travel without interfering with the main rail R. The moving rail 2 extends long toward the retreat area 4 provided on one side of the track L.

As shown in FIGS. 3 and 5, the cart 3 is
It has a structure in which a deck plate is stretched on the upper surface of a frame 5 made of channel steel or the like, and wheels 6 that roll on the moving rail 2 are provided. In this case, as shown in FIG. 3, by providing two pairs of front and rear wheels 6 along the traveling direction, it is possible to stably move even if the moving rail 2 is divided. The wheels 6 are driven by a motor (not shown).

As shown in FIG. 1 and FIG. 3, the carriage 3 is provided with a transfer rail 8 on which a rail car 7 for work or track maintenance is mounted so as to run freely. Needless to say, the transfer rails 8 are arranged at the same interval as the main line rails R and extend in parallel with the main line rails R. Since the carriage 3 runs on the moving rail 2, the upper surface of the carriage 3 is necessarily higher than the main rail R. Therefore, as shown in FIG. 1, FIG. 2, FIG. 4, etc., a pair of tong rails are provided at both left and right ends of the bogie 3 to guide the rail car 7 to move between the bogie 3 and the main rail R. The tongue-like rail 9 is mounted so as to be pivotable. The tongue rail 9 is formed in a tapered shape so that the height decreases toward the tip.

For example, as shown in FIG.
At the base of the truck 3 with the bracket 10 and the pin 11
Is pivoted to. A pair of tong rails 9 are integrally connected by a reinforcing bar 12 and a shaft 13, and a hydraulic cylinder 14 is mounted between the shaft 13 and the truck 3. The hydraulic cylinder 14 is pivotally connected to a bracket 15 provided on the carriage 3 by a pin 16 so as to be freely rotatable. The hydraulic cylinder 14 is located above the center of rotation of the tongue rail 9.

As shown in FIG. 4 (B), the rear end face 9a of the tongue rail 9 is pivoted so that the tongue rail 9 can rotate without interfering with the tip of the transfer rail 8. (Pin 16) is formed on an arc surface.
Therefore, if the piston rod 14a of the hydraulic cylinder 14 is protruded while the carriage 3 is advanced into the track L, the pair of tongue rails 9 can be tilted down on the main line rail R and rotated, and the piston rod 14a retreats. When this is done, the tongue rail 9 jumps up and turns upright.

As in this embodiment, a hydraulic cylinder 14 for rotating the tong rail 9 is connected to a pair of tong rails 9.
When disposed between the hydraulic cylinders, there is an advantage that the workability and safety can be improved because the hydraulic cylinder 14 does not obstruct the operator. As schematically shown in FIG. 1, a hydraulic unit 18 for driving the hydraulic cylinder 14 is provided at an edge of the truck 3.

As shown in FIG. 1, FIG. 3, FIG.
At the left and right ends of the vehicle, the railcar 7 is moved from the main rail R to the bogie 3
Pulleys 20 for pulling up are respectively arranged, and a drum 22 for winding a wire 21 wound around the pulley 20 is provided on a side edge of the carriage 3. The drum 22 is driven by a motor 23 with a speed reducer. FIG. 4 (A)
As shown in FIG. 5, the pulley 20 is mounted on a holder 25 so as to be freely rotatable horizontally.
Is mounted to be rotatable up and down by pins 27. Accordingly, the pulley 20 is horizontally rotatable around the axis of the rotating shaft 26 as shown in FIG. 4A, and is vertically rotatable about a pin 27 as shown in FIG.

When the pulley 20 is configured in this manner, even if the hooking position of the wire 21 on the rail car 7 is shifted, the shift is automatically corrected by the rotation of the pulley 20, and the rail car 7 is moved. Since the holder 25 rotates so as to be raised as approaching the pulley 20, no excessive force is applied to the pulley 20. Therefore, the rail car 7 is safely pulled up onto the bogie 3 in a comfortable state. be able to. There is also an advantage that the tongue rail 9 can be made compact.

The holder 2 of the pulley 20 has a wire 2
Pin 25 for preventing 1 from coming off pulley 20
Project downward. As shown in FIG. 1, an operation box 28 for moving the carriage 3, driving the winding drum 22, operating the tong rail 9, and the like is provided on an edge of the carriage 3 opposite to the winding drum 22. A portion near the operation box 28 is used as a boarding area 20 for workers. As shown in FIGS. 6 and 7, a lock hole 31 through which the lock pin 30 can be inserted and removed from above, and a lock pin 30 that is removed from the lock hole 31 as part of the lock means are provided at the edge of the boarding area 29. And a temporary insertion hole 32 for inserting the same.

In this case, by lowering the upper surface of the place where the lock hole 31 is formed, the lock pin 30 is inserted into the lock hole 31.
When the lock pin 30 is inserted into the temporary insertion hole 32, the lock pin 30
0 is set so that it hardly projects from the lower surface of the cart 3. An annular groove 33 is formed at an intermediate height of the lock pin 30, while the bogie 3 has a first limit switch 34 which is turned on when the lock pin 30 is inserted into the lock hole 31, and a temporary insertion hole 32. A second limit switch 35 which is turned ON when the lock pin 30 is inserted is attached, and the contacts 34 a and 35 b of the limit switches 34 and 35 are set so as to fit into the annular groove 33 of the lock pin 30.

Then, as shown in FIG.
On the ground G, the lock member 36 which does not interfere with the bogie 3 is fixed to the portion located below the lock hole 31 in the night-car state where the bogie 3 is retracted with the anchor bolt 38,
The lock member 36 has an engagement hole 37 through which the lock pin 30 inserted into the lock hole 31 can be inserted and removed.
The engagement hole 37 is formed as a long hole that extends long in a direction orthogonal to the moving direction of the carriage 3. This is to absorb an installation error of the moving rail 2 and a dimensional error of the carriage 3.

In the present embodiment, the ground G of the evacuation area 4 has a downward gradient of about 1/30 in tangent display (may be flat) so as to become lower as it goes away from the orbit L. When the first limit switch 34 is ON, the traveling motor is not driven, and the first limit switch 34 is turned off.
The FF is related so that the traveling motor (and other devices) can be driven only when the second limit switch 35 is ON.

Therefore, it is possible to reliably prevent an unexpected situation in which the truck 3 moves into the track L due to some mistake or an earthquake while the truck 3 is staying in the evacuation area 4. In this case, the driving motor or the like is not energized unless the first limit switch 34 is turned off and the second limit switch 35 is turned on. Therefore, the bogie 3 is driven while the lock pin 30 is inserted into the lock member 37 in the locked state. An erroneous operation can be reliably prevented. Further, loss of the removed lock pin 30 or erroneous placement of the lock pin 30 on the track L, the moving path of the traverser 1, or the like can surely be prevented from causing an accident.

The above embodiment is a was the case of using a locking pin as a movable locking member constituting the locking means, the movable locking member may be in other forms, also fixed to the movable locking member engages lock member may be in the form of merely providing a groove or hole in the ground. That is, the movable lock member and the fixed lock member may be in other engagement forms.
Further, the position where the locking means is provided may be anywhere. However,
When the locking means is manually operated, it is preferably provided near the work area as in the embodiment.

The movable lock means such as a lock pin may be remotely driven by a power drive means such as a hydraulic cylinder or a pneumatic cylinder. Further, it goes without saying that the detection means is not limited to the limit switch as in the embodiment, and various other sensors such as a photoelectric switch can be used. In addition, it is desirable to lock the traverser in a state where the traverser is advanced to the track. In this case, a movable lock member such as a lock pin for a night car lock is used, and this is fitted to a receiving portion provided on the ground or the like. (In this case, the movable lock member may be manually operated, or may be remotely operated using a sensor or the like).
In this way, there is an advantage that locking can be performed both at the time of forward movement and at the time of backward movement without complicating the structure.
