2. Description of the Related Art Two tunnels for laying a single-rail track in the ground
In the work to excavate, after excavating one outward side tunnel from the starting shaft to the reaching shaft, this time while excavating the returning tunnel parallel to the tunnel from the reaching shaft to the starting shaft. Rails are laid inside each tunnel, and excavated earth and sand are discharged by running traveling vehicles such as Toro trains on the rails that are laid as the tunnel is advanced.

The excavated earth and sand is discharged to the ground side through the earth and sand discharge facility installed in the starting shaft during the tunnel excavation on the outward path, and the transportation of the segment for tunnel lining is also started. The vertical shaft is used as a work base. It is not only costly to relocate such equipment to the arrival shaft when excavating the return tunnel from the inside of the arrival shaft to the starting shaft, but it is also difficult to discharge earth and sand from the arrival shaft to the ground. Since it may not be possible due to road conditions on the ground, the starting shaft will be used as a work base with the above-mentioned facilities at all times. The transfer device provided in the above has transferred a traveling vehicle such as a Toro train or a segment trolley from a rail end in one tunnel to a rail end in the other tunnel.

As such a transfer device, a straight guide rail is laid in the reaching shaft in a direction orthogonal to the opening ends of both tunnels, and a short rail is laid on the upper surface of the underframe on the straight guide rail. The moving carriage is arranged so as to be capable of reciprocating in a direction orthogonal to the tunnel. The moving carriage is moved to one tunnel opening end, and the short rail on the underframe is opened to the tunnel opening. After joining the rail end in the tunnel laid at the end and moving the traveling vehicle on that rail on the short rail, move it on the straight guide rail toward the other tunnel to move the short rail. It is joined to the rail end laid in the tunnel so that the traveling vehicle can be moved from the short rail to the rail in the tunnel.

[0005]

However, since the space in the reaching shaft is small, the rail on the moving carriage can be set to a length such that several traveling carriages can be mounted while the traveling carriages are connected. Therefore, when moving the traveling vehicle from the rail end on the tunnel side to the short rail on the truck, first disconnect the connection between the traveling vehicles and then move one traveling vehicle on the short rail. As described above, the traveling vehicle is moved to the other rail on the side of the tunnel by linear movement of the traveling vehicle, and this is repeated to transfer a plurality of traveling vehicles to the other rail on the tunnel and then to connect them. Not only the procedure is required and the work is extremely troublesome, but the work efficiency such as the discharge of the earth and sand is reduced, which in turn affects the tunnel excavation process.

Instead of the transfer device as described above, the rail ends in both tunnels are connected by a semicircular rail, and the traveling vehicle makes a U-turn between the rails in both tunnels on this bent rail. It could be configured to move, but
Since the distance between the rails in both tunnels is narrow, it is not possible to lay rails with a degree of bending that allows traveling vehicles to travel. SUMMARY OF THE INVENTION It is an object of the present invention to provide a reversing transfer device for a traveling vehicle between the ends of a double-track rail that can completely eliminate the above-mentioned problems.

[0007]

In order to achieve the above-mentioned object, a reversing transfer device for a traveling vehicle between double-track rails according to the present invention is designed so that a rail is moved from one rail end to the other rail end of the double-track rail. Is a device for reversing and transferring the traveling vehicle in a U-turn shape, wherein a reciprocating carriage is disposed between both rail ends, and a curve of a fixed length having a radius of curvature on which the traveling vehicle can travel. A rail is laid, and an arc-shaped running path having a radius smaller than the radius of curvature of the curved track on the moving carriage is provided between both ends of the moving carriage, and the moving carriage is moved on the arc-shaped running path. One end of the upper curved rail is joined to one rail end of the double-track rail, and the other end is joined to the other rail end.

[0008]

[Operation] The moving carriage is moved along the arcuate running path, one end of the curved track laid on the upper surface thereof is joined to one end of the double track, and then the running vehicle on the track is run. It is transferred on the lever track. At this time, the curved rail on the moving carriage has a radius of curvature that allows the traveling vehicle to travel,
In addition, since several traveling vehicles can be laid on the truck so that the traveling vehicle has a length that can be placed, the several traveling vehicles can be transferred onto the curved track of the traveling vehicle while being connected. be able to.

Then, when the moving carriage is moved toward the other rail end on the arcuate traveling path, the radius of the arcuate traveling path is smaller than the radius of curvature of the curved rail, so that the space between the two rails is narrow. Also in the above, the other end of the curved rail can be joined to the other rail end of the double-track rail while moving the movable carriage so as to be largely inverted in a small space. After joining, the traveling vehicle on the rail is run and transferred on the other rail.

The vehicle is returned to the work base 11 such as the earth and sand discharging section and the segment loading section in the starting shaft 1 by reversing the rail 3 toward the rail 3 side. In this case, the distance between the rails 3 and 4 ends of the both tunnels 6 and 7 is narrow,
Even if a semi-circular rail for laying the traveling vehicle 10 directly from one rail 3 to the other rail 4 is laid, the radius of the rail should be less than the minimum radius that the traveling vehicle 10 can travel. It cannot be done. It should be noted that the traveling vehicle 10 also includes a starting vehicle that pulls excavated earth and sand or transported earth and sand such as segments.

The reversing transfer device 9 has a curved rail 12 laid and fixed on the upper surface thereof, which has a radius of curvature larger than the minimum radius of travel of the traveling vehicle 10, that is, a curvature radius of travel of the traveling vehicle 10.

And the width of the reaching shaft 2 in the tunnel length direction, that is, the width of the reaching shaft 2 longer than the distance between the facing inner and outer wall surfaces 2a and 2b and perpendicular to the tunnel length direction. It is formed in a curved oblong plate shape along a short plane rectangular shape or arcuate running path 14.

The curved rail 12 on the moving carriage 13 is laid and fixed at the same height as the rails 3 and 4 in the tunnel, one end of which is the end of the rail 3 on the outward path and the other end of which is Each of the rails 4 on the return path can be brought into and out of contact with the other end thereof, and the rail width of the curved rail 12 is the same as that of the both rails 3 and 4,
The movable carriage 13 is installed in a state of being gently curved in the length direction, and both ends thereof are aligned with one end edges of both end surfaces of the movable carriage 13. On the other hand, the arcuate path 14 for guiding the moving carriage 13 is formed so that its radius of curvature is smaller than that of the curved rail 12 and is lower than the double track rails 3 and 4 on the bottom of the reaching shaft 2. It is formed on the upper side, and its both ends are faced in the vicinity of the ends of the double-track rails 3 and 4, and both ends are curved in a direction separating from the extension line of the double-track rails 3 and 4 to the outside, and then bent in a semicircular shape. It is in the state of doing.

The wheels 15 and 16 which are rotatably supported on the lower surfaces of both ends of the moving carriage 13 are placed on the traveling path 14 so that the rotation direction thereof is directed to the tangential direction of the arcuate traveling path 14. is there. In addition, the width of the traveling path 14 may be wide, and the point is that the wheels are
It suffices if 15 and 16 can roll. Also, a mobile trolley
Wheels traveling on the traveling path 14 may be provided on the lower surface of the central portion of the length direction 13.

When the long moving carriage 13 is movably arranged on the arc-shaped running path 14 having a small radius of curvature laid in this way, as shown in FIG. 2, it reaches one end side of the moving carriage 13. The curved track 12 on the truck is brought close to the inner wall surface 2a of the vertical shaft 2.
In a state in which one end of the vehicle is joined to the end of the outward rail 3, the moving carriage 13 is inclined from the outgoing rail 3 toward the center of the outer wall surface 2b of the reaching shaft 2, and from this state When 13 is made to travel on the arc-shaped running path 14, one end side of the running path 3 once moves to the outside from the extension of the outward-direction rail 3 and then approaches the central portion of the inner wall surface 2a in the reaching shaft 2 while The end side moves toward the return-side rail 4 and joins the other end of the curved rail 12 on the moving carriage 13 to the end of the forward-side rail 4.

In order to drive the moving carriage 13 on the arcuate traveling path 14, as shown in FIG. 4, the wheels 15, 16 of the moving carriage 13 are moved.
Mounted so that it rotates in the tangential direction of the arc of the road 14,
It may be rotationally driven by a motor 17 installed in the moving carriage 13, or another means may be used. 1 to 3, the vertical rotating shaft 18 is rotatably erected on the bottom surface of the reaching shaft 2 at the center position of the arc-shaped running path 14 in order to reliably move the moving carriage 13 on the arc-shaped running path 14. The vertical rotation shaft 18 and the movable carriage 13 are integrally connected to each other by an arm member 19 so that the vertical rotation shaft 18 and the movable carriage 13 can travel about the rotation shaft 18. In this case, it is possible to eliminate the wheels 15 and 16 of the moving carriage 13 and slide on the smooth strip-shaped running path 14. Also,
The arc-shaped traveling path 14 may be an arc-shaped guide rail, and the flanged wheels of the moving carriage 13 may travel on the guide rail. In this case, the number of guide rails may be one or more, and the interval is arbitrary, and the interval is set by the distance between the wheel attached to the moving carriage 13 and the arc center of the guide rail.

Next, the rails 3 laid in both tunnels 6 and 7 opening toward the reaching shaft 2 as described above,
The trajectory setting of the arcuate traveling path 14 for enabling the curved rail 12 on the movable carriage 13 to be joined to the end of 4 will be described with reference to FIG. First, a radius equal to or larger than the minimum radius that the traveling vehicle 10 can travel is R, and an appropriate number of traveling vehicles 10 can be loaded into a movable carriage.

Further, after finding a point M equal to the radius R from the point a on the extension line of the line segment aO (or line segment bO), the length L of the moving carriage 13 from the point a centering on the point M is obtained.
An arc having a radius R corresponding to is drawn, and the other end point is d. Then, bisectors of the angle formed by the angles aMd and aOb are drawn respectively, and the intersection point of the two bisectors is defined as E. This point E becomes the center of the arcuate traveling path 14, and the line segment aE or d
If the arcuate path 14 is set on an arc having a radius of E, the line segment bE becomes equal to the line segment dE, and when the moving carriage 13 moves between the rails 3 and 4, the curved rail 12 on the carriage 13 Both ends can be joined so as to match the ends of the rails 3 and 4, respectively.

With this structure, after the outward tunnel 6 is built between the starting shaft 1 and the reaching shaft 2, the starting tunnel 2 is moved from the reaching shaft 2 side toward the starting shaft 1 while the returning tunnel 7 is being excavated. As shown in FIG. 1, on the rail 3 laid in the tunnel 6 on the outward path from the shaft 1 side, the starting vehicle 10a
