Configured as possible.

  Next, the cart removing method of the present embodiment will be described based on FIGS. 9 (a) to 9 (c).

  In the cart removing method of the present embodiment, the traveling path at the cart removing position in the station 11 is previously set as a lifting structure including the cart pallet 6 and the table lifter 7.

  When removing the carriage 4, the vehicle body 3 is supported by a vehicle stopper 8 (jack device), and the table 71 of the table lifter 7 is placed on the maintenance floor one level below the station 11 with the carriage pallet 6 sandwiched under the carriage 4. The truck pallet 6 is pulled out sideways by the forklift 14 together with the truck 4 on the maintenance floor S.

  Thereby, the carriage 4 is removed from the vehicle body 3. Further, the removed cart 4 is transported to a predetermined maintenance position in the maintenance floor S by the forklift 14, and heavy maintenance such as overhaul is performed on the cart 4.

  As described above, according to the present embodiment, even in the case of a new transportation system in which sufficient space (land) for constructing a garage cannot be obtained and a maintenance track cannot be provided, the maintenance floor S is provided at a level below the station building. Thus, the maintenance of the vehicle 2 becomes possible.

  More specifically, as shown in FIG. 9A, during normal times when maintenance is not performed (such as when the vehicle travels), the key member 631 of the pallet stopper 63 extends back and forth, and the cart pallet 6 moves along the travel path 5. Is spanned across the gap portion G. The table 71 of the table lifter 7 contacts the lower surface of the cart pallet 6.

  At this time, the load on the cart pallet 6 and the vehicle 2 is mainly supported by the pallet stopper 63. The key member 81 of the vehicle stopper 8 is accommodated in the stopper box 82 so as not to contact the vehicle 2.

  When removing the carriage 4 during maintenance, the vehicle 2 is first stopped above the maintenance floor S. The stop is performed so that the carts 4 before and after the vehicle 2 are positioned on each cart pallet 6.

  Next, as shown in FIG. 9 (b), a cart cradle 9 is arranged on the cart pallet 6. Specifically, the key member 81 of the vehicle stopper 8 is extended to support (hold) the vehicle 2 from below so that the vehicle 2 does not descend. With the vehicle 2 held, the key member 631 of the pallet stopper 63 is retracted to separate the cart pallet 6 from the front and rear traveling paths 5. The separated cart pallet 6 is lowered by the table lifter 7 to a predetermined height in the maintenance floor S (for example, substantially the same height as the floor). On the lowered cart pallet 6, the cart pedestal 9 is positioned and placed by a forklift 14 or the like. The cart pallet 6 is returned to the height of the traveling path 5 by the table lifter 7, and the cart cradle 9 is brought into contact with the cart 4 from below.

  Next, as shown in FIG. 9 (c), the vehicle body 3 (vehicle frame 31) and the carriage 4 are disconnected, and the carriage 4 is placed on the carriage pallet 6 while being supported by the carriage holder 9. The carriage pallet 6 on which the carriage 4 is placed is lowered to the predetermined height in the maintenance floor S by the table lifter 7. When the cart pallet 6 is lowered, the vehicle stopper 8 remains in the extended state, and the vehicle body 3 is held by the vehicle stopper 8 so that the vehicle body 3 does not descend.

  As described above, the carriage 4 can be detached from the vehicle body 3 without lifting (or lifting) the vehicle body 3. The removal of the carriage 4 may be performed simultaneously or sequentially on the front and rear carriages 4.

  As described above, according to the present embodiment, since the conventional lifting and pulling-out operation of the vehicle body 3 is not performed, a garage or the like for performing the lifting and pulling-out operation is not necessary. Further, since a garage is not required, a maintenance track for drawing the vehicle from the main track to the garage is also unnecessary. As a result, the carriage 4 can be removed from the vehicle body 3 without requiring a large site for constructing a garage or a maintenance track.

  Next, an attachment method for attaching the carriage 4 to the vehicle body 3 will be described.

  When the carriage 4 is attached to the vehicle body 3 after the carriage is removed as described above, first, the carriage 4 that has undergone maintenance is supported by the carriage base 9, and the carriage pallet 6 is lowered to the maintenance floor S. Place on top.

  Next, the cart pallet 6 is raised to the height of the traveling path 5 by the table lifter 7, and the cart 4 on the cart pallet 6 is coupled to the vehicle frame 31. Thereby, the carriage 4 is attached to the vehicle body 3.

  Next, the carriage pallet 6 is lowered to the maintenance floor S, the carriage cradle 9 is removed from the carriage pallet 6, and the empty carriage pallet 6 is raised to the height of the traveling path 5 again. After the key member 631 of the pallet stopper 63 is extended to engage the cart pallet 6 with the front and rear traveling paths 5, the key member 81 of the vehicle stopper 8 is retracted to open the vehicle 2. As a result, the traveling path 5 and the vehicle 2 can travel.

  Thus, according to the present embodiment, not only the carriage 4 is removed, but also when the carriage 4 is attached to the vehicle body 3, it is not necessary to lift the vehicle body 3.

  In addition, this invention is not limited to the above-mentioned embodiment, Various modifications and application examples can be considered.

  For example, in the above-described embodiment, the new transportation system vehicle is targeted. However, the present invention is not limited to this, and other rubber tire type vehicles or rail vehicles that run on rails may be used.

  The cart is not limited to a single-shaft cart and may be two or more shafts, or may be a slave cart without a driving means such as a driving motor.

  In the above-described embodiment, the station is provided on two or more floors, but the present invention is not limited to this. For example, the route may be provided in the basement or flat ground, and the station may be provided in the basement or the first floor. In this case, the maintenance floor S is provided in the basement. Moreover, you may provide a trolley | bogie removal facility in places other than a station (for example, main line track between stations).

  In the above-described embodiment, the cart pallet 6 is engaged with the travel path 5 by the pallet stopper 63, but the present invention is not limited to this. For example, it is conceivable that a cylinder device having a structure similar to that of the pallet stopper 63 is provided in the front and rear traveling paths 5 and the carriage pallet 6 is supported on the key member of the cylinder device. In this case, it is preferable to form a groove for inserting the key member of the cylinder device on the lower surface of the cart pallet 6. According to this, since the cylinder device is fixed to the travel path, the cylinder device can be easily connected to a power source (power source, hydraulic pressure source, etc.).

  It is also conceivable to omit the pallet stopper 63 and hold the cart pallet 6 at the height of the travel path 5 by the table lifter 7. For example, it is conceivable that the arm 73 of the table lifter 7 is provided with a lock means for restricting the operation of the pantograph type link mechanism (that is, raising and lowering of the table).

  In the above-described embodiment, the maintenance travel path is configured by the cart pallet 6, but the present invention is not limited to this. For example, as shown in FIG. 10, the cart pallet 6 may be omitted, and the table 71 of the table lifter 7 may be used as the maintenance travel path 6. In this case, a tire route portion is provided on the upper surface of the table 71. Further, in the example of FIG. 10, a groove for transport by the forklift 14 is formed in the cart cradle 9, or maintenance of the cart 4 is performed on the table 71 which is lowered to the maintenance floor S by omitting the transport of the cart 4. Can be considered.

  In addition, when the carriage is attached to the vehicle body, the carriage 4 that has been maintained in advance is prepared on the maintenance floor S, and when the carriage pallet 6 with the carriage 4 removed from the vehicle body 3 is lowered to the maintenance floor S, The cart 4 on the cart pallet 6 may be replaced with the cart 4 that has been maintained and attached to the vehicle body 3 on the cart 4 that has been maintained. Thus, when exchanging the trolley | bogie 4 which needs a maintenance with the trolley | bogie 4 which has been maintained, the traveling path 5 and the vehicle 2 can be returned to the state which can drive | work rapidly.

  In addition, it is also conceivable to maintain the carriage 4 on the carriage pallet 6 with the table lifter 7 being lowered to the maintenance floor S without using the forklift 14. In this case, since the table lifter 7 and the cart pallet 6 are used as work tables, there is no need to provide a work table in the maintenance floor S, and maintenance is possible even when the maintenance floor S is narrow. Note that the vehicle is not moved during the maintenance period.

  Moreover, in the above-mentioned embodiment, although the gap part G, the trolley | pallet pallet 6, and the table lifter 7 were provided in the same number as the number (two) of the trolley | bogie 4 per vehicle, it is not limited to this, It shows in FIG. Thus, the gap part G, the cart pallet 6 and the table lifter 7 may be one each.

  A method of replacing the carriage 4 according to the embodiment according to FIG. 11 will be described. In FIG. 11, reference numeral 4 </ b> A is attached to the maintenance target carriage requiring maintenance, rubber tires are indicated by bold lines, and reference numeral 4 </ b> B is assigned to the new carriage. Moreover, the same code | symbol is attached | subjected to the member similar to FIGS. 1-9, and description is abbreviate | omitted. For convenience of explanation, the left side of FIG.

  In this replacement method, first, as shown in FIG. 11 (a), the vehicle 2 is stopped so that the maintenance cart 4A on the front side of the vehicle 2 is positioned on the cart pallet 6, and the front side of the vehicle 2 is stopped. Remove maintenance target carriage 4A. In addition, a new carriage 4B is prepared in the maintenance space S.

  Next, as shown in FIG. 11B, a new carriage 4B is attached to the front portion of the vehicle 2 instead of the removed carriage 4A. In addition, the removed maintenance cart 4A is carried out for maintenance.

  Next, as shown in FIG. 11 (c), the vehicle 2 is moved and stopped so that the rear maintenance target cart 4 </ b> A is positioned on the cart pallet 6. Further, as shown in FIG. 11 (d), the rear maintenance target carriage 4 </ b> A is removed from the stopped vehicle 2, and a new carriage 4 </ b> B is attached to the rear portion of the vehicle 2 instead of the removed maintenance target carriage 4 </ b> A.

  As described above, the maintenance cart 4A before and after the vehicle 2 is replaced with a new cart 4B. In the embodiment of FIG. 11, since only one cart pallet 6 and one table lifter 7 are provided, the space for the maintenance space S can be saved, and the installation cost of the cart removal equipment can be reduced. .
