However, there are steep slopes in the route (mineway) between the starting base and the work place, and it takes time to transport with one driving vehicle, the amount of transportation is limited, and the operation itself is difficult. In some cases,

Therefore, it has been considered to carry out transportation by a vehicle (train) formed by connecting two driving vehicles to at least one (usually a plurality of) bogies.

In view of such an actual situation, the present invention uses two drive cars in one train to speed up transportation and return (shorten transportation and return time), while using two drive cars. In some cases, it is an issue to provide an optimum operation method.

The operation method of the construction transport vehicle according to the present invention includes the following steps (1) to (5).
(1) A vehicle composed of two drive vehicles connected to the front and rear of at least one bogie for material transportation, and transports materials from the starting base to the work place with one drive vehicle at the head. At the same time, the transport and return step of returning to the starting base side with the other driving vehicle at the head (2) During the transport and returning step, at least one other bogie at the loading position on the starting base side. Loading step of loading materials (3) The first driving vehicle is separated from the returned trolley and connected to the leading side of the loaded trolley that has finished loading the materials at the loading position. Start preparation step (4) The loaded trolley and the returned trolley are towed or pushed by one drive vehicle, respectively, the loaded trolley is moved to the starting position, and the returned trolley is moved to the starting position. Second start preparation step of moving to the loading position (5) The loaded trolley moved to the starting position by separating another driving vehicle from the returned trolley moved to the loading position. A third start preparation step, which is connected to the tail side and enables the loaded bogie to be started by two driving vehicles.

According to the present invention, when traveling between a starting base and a work place (long-distance traveling), the vehicle is towed and pushed by two front and rear driving vehicles to speed up transportation and return (transportation and return time). ), Increase the amount of transportation, etc.
Also, if you are carrying out loading work on another trolley during transportation and returning, and you return to the starting base, you can replace the returned empty trolley with the loaded trolley and restart quickly. , The transportation cycle time can be shortened by the amount of loading time.
In addition, since high-speed driving is not required to replace the returned empty trolley and the loaded trolley at the starting base, each trolley is towed or pushed by one driving vehicle.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic view of a traveling route of a construction transport vehicle showing an embodiment of the present invention, and FIG. 2 is a diagram showing an example of organization of a construction transport vehicle.

The construction transport vehicle 1 of the present embodiment is a shield tunnel construction transport vehicle, and is a track composed of a pair of rails laid in the tunnel 110 between the starting base 100 including the shaft and the work place 120 near the face. It travels along R and mainly carries in the segment (S in FIG. 2), which is a material for shield tunnel construction. That is, the segments are loaded at the starting base 100, traveled to the work place 120, and unloaded.

As shown in FIG. 2, the construction transport vehicle 1 has two drive vehicles A and B connected in front of and behind the bogie C of at least one (usually a plurality of vehicles, two in the figure) for segment transportation. It is a vehicle (train) of the formation.

The two drive vehicles A and B have the same structure as each other, and the drive vehicle A will be described as a representative.
The driving vehicle A is symmetrical in the front-rear direction and has a driver's seat 11 in the center in the front-rear direction so that the vehicle A can travel in either the front-rear direction.
The drive vehicle A also has, for example, a self-propelled motor 12 that is operated by electric power supplied from a generator (not shown) that uses a diesel engine as a drive source, and the motor 12 causes the wheels (rail wheels) 13 to be driven by the motor 12. Drive and run on the rails.
The drive vehicle A is also configured so that the rotation direction of the wheels 13 can be switched by the motor 12, whereby the traveling direction can be switched without switching the front and rear.
The drive vehicle A also has a coupler (unsigned) in the front and rear, and the bogie C can be connected in any of the front and rear directions.
The driver is boarded in the driver's seat 11 of at least the driving vehicle on the leading side in the traveling direction among the two driving vehicles A and B.

The trolley C loads and transports the segment S, which is a material for shield tunnel construction, and is towed and pushed by the driving vehicles A and B.
Therefore, the driving vehicles A and B can pull the bogie C when it is on the leading side in the traveling direction and push (boost) the bogie C when it is on the trailing side in the traveling direction.

Further, in the operation of the construction transport vehicle 1 in the present embodiment, in addition to the vehicle 1 formed by connecting two drive vehicles A and B in front of and behind at least one bogie C, FIG. As shown, at least one trolley D (two in the figure) is used. The dolly D has the same structure as the dolly C. When the trolley C is used for transporting the segment, the trolley D stands by at the loading position of the segment for the next transport.

Next, the configuration of the starting base 100 will be described with reference to FIG.
In the present embodiment, the loading position 101, the starting position 102, and the returning position 103 are set on the starting base 100 side.

The loading position 101 is set near the start end of the track R in the inner part of the starting base 100. The upper part of the loading position 101 is connected to the shaft. An elevator (segment lift) that supplies segments from the ground side is provided in the shaft above the loading position 101, and the segments can be loaded on the carriage D at the loading position.

The starting position 102 and the returning position 103 are provided in parallel by branching the track R in parallel in front of the loading position 101 in the starting base 100 (front on the face side).
Specifically, the orbits at the loading position 101 in the starting base 100 are two parallel orbits in front of the loading position 101, that is, the orbits on the starting position 102 side and the orbits on the return position 103 side. It branches to. The orbit on the starting position 102 side and the orbit on the return position 103 side merge into one orbit on the exit side of the starting base 100.

Therefore, it is possible to start from the track on the starting position 102 side and travel to the work place 120, and when returning from the work place 120 side to the starting base 100, it is possible to enter the track on the return position 103 side.
Further, the orbit on the return position 103 side can enter the orbit on the loading position 101 side, and the orbit on the loading position 101 side can enter the orbit on the starting position 102 side.

Next, the operation method when two driving cars are used for one train will be described with reference to FIG.
In the operation example of FIG. 3, as shown in FIG. 2, a vehicle 1 formed by connecting two drive vehicles A and B in front of and behind the two bogies C, and the vehicle 1 being transported and returned. Two other trolleys D, which are loaded on the trolley D, are used.

In FIG. 3A, the vehicle 1 is formed by connecting two drive vehicles A and B in front of and behind the two segment-loaded bogies C, and is towed by the drive vehicle A on the front side and on the tail side. The segment is transported from the starting base 100 to the work place 120 by being pushed by the driving vehicle B of the above.

In FIG. 3B, the segment is unloaded after the vehicle 1 arrives at the work place 120.

In FIG. 3C, after the unloading, only the traveling direction is switched, the driving vehicle B is on the front side, the driving vehicle A is on the rear side, the driving vehicle B is towed, and the driving vehicle A is pushed to perform the work. Return from the place 120 to the starting base 100. At this time, the vehicle heads for the return position 103 of the starting base 100. At this time, the trolley C is basically an empty trolley because it has been unloaded. However, the returning trolley C may be used for loading unnecessary materials (including equipment) at the work place 120 and transporting the materials (including equipment) to the starting base 100 side.

On the other hand, in parallel with the transportation and return steps of FIGS. 3A to 3C, the segment is loaded onto another empty carriage D at the loading position 101 on the starting base 100 side. Therefore, the transport and return steps and the loading steps are performed in parallel.

In FIG. 3D, the vehicle 1 returns to the return position 103 of the starting base 100. At this time, the loading of the segment into another trolley D at the loading position 101 has been completed, and the trolley D that has already been loaded is waiting at the loading position 101.

Then, as shown in FIGS. 3 (e) to 3 (h), preparation for restart (reorganization of the vehicle) is performed.
In FIG. 3 (e), one drive vehicle B on the front side at the time of return is separated from the returned trolley C and connected to the front side of the loaded trolley D at the loading position 101 (first start preparation). Step).
In other words, one drive vehicle B separated from the carriage C that has returned to the return position 103 is moved from the return position 103 to the loading position 101 and connected to the leading side of the loaded carriage D.
As a result, the returned trolley (empty trolley) C can be moved by the driving vehicle A, and the loaded trolley D can be moved by the driving vehicle B.

In FIGS. 3 (f) and 3 (g), the loaded trolley D and the returned trolley C are towed or pushed by one drive vehicle, respectively, and the loaded trolley D is moved to the starting position 102. The returned carriage C is moved to the loading position 101 (second start preparation step).
Specifically, first, as shown in FIG. 3 (f), the loaded carriage D is towed by the driving vehicle B and moved from the loading position 101 to the starting position 102.
Next, as shown in FIG. 3 (g), the returned carriage C is pushed by the driving vehicle A to move from the return position 103 to the loading position 101.

In FIG. 3 (h), another drive vehicle A is separated from the returned trolley C that has been moved to the loading position 101, and is connected to the tail side of the loaded trolley D that has been moved to the starting position 102. The loaded bogie D can be started by two drive vehicles B and A (third start preparation step).
In other words, another drive vehicle A separated from the returned trolley C that has been moved to the loading position 101 is moved from the loading position 101 to the starting position 102 and connected to the tail side of the loaded trolley D. ..
As a result, the two drive vehicles B and A are connected to the front and rear of the loaded carriage D that has been moved to the start position 102, and the construction transport vehicle 1 is reorganized so that the vehicle can start.

In FIG. 3 (i), a vehicle 1 formed by connecting two drive vehicles B and A to the front and rear of the loaded bogie D is towed by the front drive vehicle B and is towed by the rear drive vehicle A. To carry the segment from the starting base 100 to the work place 120. This is only the front and rear of the driving vehicles A and B being exchanged with respect to FIG. 3A. Then, during such transportation, loading of the segment on the returned carriage (empty carriage C) at the loading position 101 is started.

Therefore, according to the present embodiment, when traveling between the starting base 100 and the work place 120 (long-distance traveling), the trolley C is towed and pushed by the two front and rear driving vehicles A and B. It is possible to speed up transportation and return (shorten transportation and return time), increase the amount of transportation, and so on. In addition, since there is always a driving vehicle on the leading side in the traveling direction and a driver can be assigned to the leading vehicle, it is possible to drive while checking the front, which is also advantageous in terms of safe operation.

Further, according to the present embodiment, during the transportation and the return, the loading work is performed on another trolley D, and when the vehicle returns to the starting base 100, the returned empty trolley C and the loaded trolley D are used. Since it is possible to start quickly by exchanging with, the cycle time of transportation can be shortened by the amount of loading time.

Further, according to the present embodiment, since high-speed running is not required to replace the returned empty trolley C and the loaded trolley D at the starting base 100, each trolley is used as a driving vehicle. Since it is towed or pushed more, it can be carried out efficiently with the minimum number of driving vehicles and therefore in a small space.

Next, a case of carrying out with a plurality of trains will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing an example of organization in that case, and FIG. 5 is an explanatory diagram of an operation method in that case.

In the formation example of FIG. 2, one vehicle 1 consisting of at least one bogie C and two drive vehicles A and B is used, and further, the rolling stock 1 is loaded at the starting base while the vehicle 1 is running. , Another dolly D is used.
On the other hand, in the formation example of FIG. 4, the vehicle 1 consisting of at least one bogie C and the two driving vehicles A and B, and at least one bogie E and the two driving vehicles A and B A vehicle 2 composed of the above is used, and these two vehicles 1 and 2 are driven between the starting base 100 and the work place 120. Further, another bogie D is used for loading at the starting base while the vehicles 1 and 2 are traveling.

In the operation example of FIG. 5, while the vehicle 1 composed of the driving vehicles A and B and the bogie C is being transported to the work place 120, the vehicle 2 composed of the driving vehicles A and B and the bogie E is the starting base. Return to 100.

However, when two trains 1 and 2 are used, it is necessary to allow the vehicles 1 and 2 to pass each other between the starting base 100 and the work place 120. As a method of enabling the passing, the double tracking of the track R, the setting of the passing point by the branch line, and the like can be mentioned.

In the operation example of FIG. 5, the vehicle 1 and the vehicle 2 pass each other at a branch line (passing point) provided in the middle of the tunnel 110.

In the case of the operation example of FIG. 5, when the vehicle 2 (trolley E) returns, the empty trolley E and the loaded trolley D are exchanged to start, and the trolley E is loaded.
Next, when the vehicle 1 (trolley C) returns, the empty trolley C and the loaded trolley E are replaced with each other to start the vehicle, while loading the trolley C.
In this way, by using the two trains 1 and 2, the total amount of transportation can be increased.

It is also possible to carry out with two or more trains of n trains. In this case, it is preferable that the number of drive cars is 2 × n and the number of bogies is n + 1 as a whole. In the present embodiment, the bogies C to E are formed of two bogies, but the bogies are not limited to two and may be one or more. Further, although the number of driving cars is the same (two cars) in each formation, the number of bogies may be different.

It should be noted that the illustrated embodiments merely illustrate the present invention, and the present invention includes various improvements and improvements made by those skilled in the art within the scope of claims, in addition to those directly shown by the described embodiments. It goes without saying that it involves changes.
For example, in the above embodiment, the vehicle runs on the track, but it may run on the road surface by the tire wheels, and in this case as well, it can be carried out without providing a turning space.
