  FIG. 13 is a schematic plan view showing an example of the layout of the mobile bogie travel line that is installed when the inside of the tunnel between the subway A station and the subway B station is constructed.

  As shown in FIG. 13, when a subway track is constructed, the following procedure is performed. First, a tunnel 3 that is a subway track is constructed in the horizontal direction from the shaft 1 of the subway A station to the shaft 2 of the subway B station. After the tunnel 3 is constructed, the tunnel 4 is constructed in the horizontal direction in the underground from the shaft 2 of the subway B station to the shaft 1 of the subway A station. In addition, when constructing the tunnel 3 from the shaft part 1 of the subway A station and the tunnel 4 from the shaft part 2 of the subway B station, in order to run a plurality of vehicles for carrying in materials such as segments and carrying out earth and sand, Traveling rails 5a and 5b as traveling paths are sequentially laid in tunnels 3 and 4 in the middle of construction.

  When the tunnel 4 is constructed, a group of vehicles that have traveled on the traveling rail 5a of the tunnel 3 from the shaft 1 of the subway A station and have entered the shaft 2 of the subway B station carry new materials into the tunnel 4. Therefore, in order to load earth and sand, it is transferred to the traveling rail 5b in the tunnel 4 by the traverser device 6 installed at the bottom 2a of the shaft section 2 of the subway B station, and is transferred to the construction position and the earth and sand loading position. .

  FIG. 14 is a schematic enlarged layout view of the traverser device 6 installed at the subway station B shown in FIG. As shown in FIG. 14, the traverser device 6 is installed between a position connecting to the traveling rail 5 a of the tunnel 3 and a position connecting to the traveling rail 5 b of the tunnel 4 at the bottom 2 a of the shaft section 2 of the subway B station.

  Then, the traverser device 6 puts a plurality of vehicles 9, 9... That have been connected and traveled with, for example, a locomotive, which is a powered vehicle, one by one on the traverser 8. The vehicle is stopped so that the vehicle 9 does not move. Next, when the connection between the vehicle 9 on the traverser 8 and the rear side vehicles 9, 9... Is disconnected and the traverser 8 is moved laterally, the vehicle 9 on the traverser 8 and the rear side vehicles 9, 9. The remaining vehicles 9, 9... Are moved rearward to a position where they do not contact.

  Next, the traverser 8 is moved sideways to the position of the traveling rail 5b, and the vehicle stop is removed after the movement. Thereafter, the vehicle 9 on the traverser 8 is transferred onto the traveling rail 5b by a manual push operation, and is connected to the vehicle 9 that has already entered the line. Further, the vehicle 9 is transferred from the traverser 8 to the traveling rail 5 b of the tunnel 4, and the traverser 8 that has been emptied is laterally moved back to the position of the traveling rail 5 a of the tunnel 3. This is repeated sequentially one by one. When all the vehicles 9, 9,... Have moved to the traveling rail 5 b of the tunnel 4, they are further transferred to the construction position and the sediment transport position in the tunnel 4.

  In the above example, the case where the subway track between the subway A station and the subway B station is constructed has been described. However, it may also be applied to a route that makes a U-turn in a middle shaft or the like in a water and sewerage system or a common ditch. The method of passing a vehicle including a motor vehicle on a track including a curved portion that bends in a U-turn shape generally uses a structure called a traverser that can move at right angles as shown in FIGS. Is.

  Moreover, as a method of moving a plurality of movable carriages on a curved track, for example, those described in Patent Documents 1 and 2 are known. However, the moving cart apparatus proposed in Patent Document 1 does not have a structure in which a plurality of moving carts moving on a curve are connected to each other.

  The connecting means 30 is composed of a pair of left and right connecting mechanisms 31 and 32 that are provided separately on the left and right (inner side and outer side of the curve) on the front and rear surfaces of the movable carriages 22, 22. That is, as shown in FIG. 1, the coupling mechanism 31 is provided at an inner portion that is on the inner side of the curve when traveling on a curve, and the coupling mechanism 32 is provided on an outer portion that is on the outer side of the curve when traveling on a curve.

  As shown in FIG. 3, the connecting mechanism 31 is a pair of upper and lower connecting pieces 33 each having a flat shape protruding horizontally from the rear surface 22 a of the front movable carriage 22 toward the front surface 22 b of the rear movable carriage 22. , 33, a plate-like connecting piece 34 projecting horizontally from the front surface 22a of the rear moving carriage 22 toward the rear face 22a of the front moving carriage 22, and the connecting pieces 33, 33 and the connecting piece. 34 is provided with a connecting pin 35 that connects to 34.

  As shown in FIG. 4, the connecting pieces 33, 33 and the connecting piece 34 have mounting holes 36a, 36a and mounting holes 36b penetrating in the vertical direction at positions corresponding to each other. Then, the connecting piece 34 is inserted between the connecting piece 33 and the connecting piece 33, and the connecting pin 35 is inserted into the mounting holes 36a, 36a, 36b in common at the positions corresponding to the mounting holes 36a, 36a, 36b, The connection pins 35 connect the connection pieces 33, 33 and the connection piece 34 so as not to be detached. Moreover, if the connection pin 35 is removed, the connection between the connection pieces 33 and 33 and the connection piece 34 can be released.

  In the connection mechanism 31, contrary to the structure shown in FIG. 3, a pair of upper and lower connection pieces 33, 33 project from the front surface 22b of the rear moving carriage 22 toward the rear surface 22a of the front moving carriage 22, The connection piece 34 may project at a right angle from the rear surface 22a of the front movable carriage 22 toward the front surface 22b of the rear movable carriage 22. Further, the connection pieces 33 may be provided with only the upper or lower connection piece 33 without providing a pair of upper and lower connection pieces.

  As shown in FIG. 5, the connecting mechanism 32 is a pair of upper and lower connecting pieces 37 having a flat shape projecting horizontally from the rear surface 22a of the front moving carriage 22 toward the front surface 22b of the rear moving carriage 22. , 37, a plate-like connecting piece 38 projecting horizontally from the front surface 22a of the rear moving carriage 22 toward the rear face 22a of the front moving carriage 22, and the connecting pieces 33, 33 and the connecting piece. 34 is provided with a connecting pin 39 that connects to 34.

  As shown in FIG. 6, the connecting pieces 37 and 37 have mounting holes 40a and 40a penetrating in the vertical direction at positions corresponding to each other, and a connecting pin 39 is inserted into the mounting holes 40a and 40a. The connecting pin 39 is attached to the connecting pieces 37 and 37. On the other hand, on the side of the connecting piece 38, a half-moon-shaped engaging notch 40b that can be received by contacting the peripheral surface of the connecting pin 39 on the tip side is formed. When the engagement notch 40b is brought into contact with and engaged with the peripheral surface of the connecting pin 39 and the rear moving carriage 22 is pushed against the front moving carriage 22, the connection pin 39 and the connecting piece 38 When the rear moving carriage 22 is braked on a straight line, the connecting pin 39 and the connecting piece 38 are separated to move forward. Only the carriage 22 can be moved forward by inertia.

  In the coupling mechanism 32, a pair of upper and lower coupling pieces 37, 37 project from the front surface 22b of the rear movable carriage 22 toward the rear surface 22a of the front movable carriage 22 in the opposite manner to the structure shown in FIG. The structure in which the piece 38 protrudes at right angles from the rear surface 22a of the front movable carriage 22 toward the front surface 22b of the rear movable carriage 22 may be employed. Further, it is not necessary to provide a pair of upper and lower connecting pieces 37, but only upper or lower connecting pieces 37 may be provided.

  Further, the connecting means 30 when the direction of turning direction is two directions like a crank shape is provided separately on the left and right (inner side and outer side of the curve) on the front and rear surfaces of the movable carriages 22, 22. The left and right pairs may be constituted by the connecting mechanism 32.

  In this case, even if it stops in the middle of the curved portion, the connection is not disconnected due to inertia, but there is a possibility that the straight portion is disconnected. This preventive measure only needs to connect the mobile trolleys 22 with rubber, a spring or the like at the left and right connecting positions.

  Next, the operation will be described. When the vehicle group 11 is transferred from the first traveling rail 5a in the tunnel 3 to the second traveling rail 5b in the tunnel 4, the moving carriages 22, 22. Move to the end of the traveling rail 5a. When the moving carriages 22, 22 ... are moved to the end of the first running rail 5a, the main running rail 5a and the moving carriage upper rails 23, 23 ... on the moving carriages 22, 22 ... correspond to the same height.

  In this state, when the vehicle group 11 is moved to the moving carriage 22 side by the traction force of the power vehicle 25a, one vehicle 25 can be transferred onto each moving carriage 22 without breaking the connection of the vehicle group 11. . In addition, when the vehicle group 11 is transferred onto each of the movable carriages 22, 22..., The direction change running rails 21 are moved to the second traveling rail 5b by moving the connected movable carriages 22, 22. Drive up with a boost drive.

  In the straight running, as shown in FIG. 7, the front and rear portions of the movable carriages 22 and 22 are moved while being in contact with each other with no gap as a result of the connection by the connection mechanisms 31 and 32. On the other hand, in the vertical shaft 2 which is the direction change position, the vehicle travels in a curved shape with a U-turn. In this curved traveling, as shown in FIG. And the rear part moves without contact. On the other hand, on the outside of the curve, the connecting mechanism 32 separates the connecting pin 39 and the connecting piece 38 so that each movable carriage 22 can be bent. Accordingly, the moving carriages 22, 22... Smoothly turn around the curved portion with the vehicle group 11 mounted thereon and head toward the second traveling rail 5b.

  When the moving carriages 22, 22 ... are moved to the end of the second traveling rail 5b, the moving carriage upper rails 23, 23 ... on the moving carriage 22, 22 ... correspond to the second running rail 5b at the same height. . Then, when the vehicle group 11 is moved to the second traveling rail 5b side by the driving force of the driving vehicle 25a, the vehicle group 11 on each movable carriage 22 can be transferred onto the second traveling rail 5b without breaking the connection. it can.

  The above describes the case where the vehicle group 11 is transferred from the first traveling rail 5a in the tunnel 3 to the second traveling rail 5b in the tunnel 4, but the second traveling rail 5b in the tunnel 4 and the second traveling rail 5b in the tunnel 3 In the case of transfer to the one traveling rail 5a, the transfer can be performed by the same method except that the moving direction is opposite.

  After the vehicle group 11 is transferred to the moving carriage 22 from the travel rail 5a or 5b, the moving carriage 22 travels while the vehicle group 11 is connected, or the connection is released and the moving carriage 22 travels. There is a way to do it. When the moving carriage 22 travels in a curved line while the vehicle group 11 is connected, the inner side of the curve approaches because the arc is short, but the outer side of the long arc leaves away, so that the vehicle center interval of each vehicle connecting position of the vehicle group 11 is also different. Although it becomes wide similarly, it can respond to making the pin hole of a connecting rod into a long hole by a connection method.

  Further, when the vehicle group cannot be moved while being connected, such as when the pin hole of the connecting rod cannot be made into a long hole by a connecting pin method with a special connecting device or the like, it is released.

  Therefore, according to this structure, it is necessary to change the direction from the first or second traveling rail 5a, 5b to the second or first traveling rail 5b without disconnecting the connection of the vehicles 25 constituting the vehicle group 11. , 5a can be smoothly transferred, so that the time required for the movement of the connected vehicles 25, 25... Can be shortened. Moreover, it can switch without spending much human power. Furthermore, in the construction of a subway tunnel or the like, when constructing a single-line parallel line portion that makes a U-turn at 180 °, it is necessary as a construction site up to the home portion, but in the present invention, it can be constructed by using only a shaft portion. . Use of the home part does not affect the home part construction process.

The moving cart group 60 shown in FIG. 12 includes a front moving cart 61a, a rear moving cart 61b, and three intermediate moving carts 61c disposed between the front moving cart 61a and the rear moving cart 61b, 61c, 61c.

  The rear part of the front moving carriage 61a is a female arc part 62a recessed in an arc shape, and the front part of the rear moving carriage 61b is formed as a male arc part 62b protruding in an arc shape. Further, the front part of the intermediate moving carriage 61c is formed as a male arc part 62b and the rear part as a female arc part 62a. The radii of the female arc part 62a and the male arc part 62b are formed to be smaller than the radius of the curved part that runs in a curved line.

  The moving carriage 61a, the moving carriages 61c, 61c,... And the moving carriage 61 are arranged at the center of the plane of the circle of each male arcuate part 62b with the male arcuate part 62b in contact with the female arcuate part 62a. Corresponding to the center position of the traveling rail 21 for direction change, the front moving carriage 61c and the rear moving carriage 61c are connected to the center position through a connecting pin 63 in a state of being rotatable in the horizontal direction. ing.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.

  For example, although only two types of moving carts, a rectangular moving cart and an arc shape, have been proposed, the front and rear contact surfaces of each moving cart are perpendicular to the traveling direction of the moving cart only between the two rails of the moving cart upper rail 23. And there is also a method of making the front and rear ends in a state where the outer corners of the rail are dropped into a trapezoidal shape. By using a trapezoidal shape, the outward opening at the curved portion can be reduced.

  In addition, when the connection position in this case is made the center of the traveling rail 21 for direction change, it can respond by making the pin hole of a connection pin into a long hole. In this case, the length of the long hole may be equal to or greater than the distance between the front part and the rear center part of each moving carriage when the moving carriage is running along a curve. The driving method is that each moving vehicle when the vehicle group is transferred from the first traveling rail 5a or the second traveling rail 5b to the moving vehicle and when the vehicle group is transferred to the second traveling rail 5b or the first traveling rail 5a. Since the front part and the rear part of each other need to be in contact with no gap, the boosting operation is performed.

  In addition, the movable carriages 22, 61a, 61b, 61c and the vehicle group 11 are not limited to rails that travel and move while being guided by rails, but have a structure that moves on a passage with tires or that is driven by being pulled by a chain or the like. Therefore, the present invention includes a case where the vehicle is moved by these traveling methods.

  Furthermore, although the connection means 30 showed the Example mainly by the structure in the connection mechanisms 31 and 32, a connection pin is attached to each of the front surface 22b of the rear side mobile trolley 22 from the rear surface 22a of the front side mobile trolley 22.
