Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle loading/transporting device for transporting a vehicle on a special electric transport vehicle through a tunnel or the like.

Generally, when a car or the like is driven under its own power in a tunnel, the exhaust gas emitted by the internal combustion engine remains in the tunnel, and unless strong ventilation is performed, the air inside the tunnel becomes contaminated and becomes extremely dangerous.
For this reason, the tunnel is equipped with a powerful ventilation system,
In the case of long tunnels, the tunnel used for this ventilation air passage may be much larger, which increases the amount of tunnel excavation, which is directly linked to the tunnel construction cost.
It has become a very big problem. At this point, people are beginning to think of ways to use electric drive to transport cars inside tunnels, but development is still in its infancy and there are many unresolved problems.

The purpose of the present invention is to stop the internal combustion engine of a car in a long tunnel etc. and transport it using a special electric transport vehicle. The purpose of this project is to provide a vehicle structure and a guiding structure for its running route, thereby reducing air pollution within the tunnel, reducing the required volume of the ventilation tunnel, and reducing the overall construction cost.

An embodiment of the present invention will be described below with reference to the drawings.
First of all, in Figs. 1 to 3, 1 indicates an electric transport vehicle, and 2 is a loading platform of the transport vehicle 1 for loading automobiles. Only the outline is shown. This loading platform 2 has a size that allows a vehicle A such as a bus as shown in FIGS.

The auxiliary guide wheels 15a and 16b are arranged below the guide wheels 15a and 16b.

In addition, the loading platform 2 has both sides 2a, 2 on the left and right upper surfaces.
Banks 17 and 18 are provided along b to prevent the automobile A from falling off the loading platform 2 during transportation, and at the same time, the loading platform 2 is configured to have the strength to withstand the load of the automobile A. The structure is such that the height of the floor surface on which A rides is made as low as possible. In addition, a spring mechanism (not shown) is incorporated into the spindles of the core plate mechanisms 5, 6 and the running wheels 9..., 10 of the trolleys 3, 4 in order to receive the load of the loading platform 2 evenly. It is preferable to do so. Furthermore, the above-mentioned running wheels 9...10...... and guide wheels 13
a, 13b, 14a, 14b auxiliary guide wheel 15a,
15a, 15b, and 15b are all made of rubber tires for reasons such as noise prevention.

On the other hand, talking about the running path on which the electric transport vehicle 1 described above runs, the running path 19 shown in FIGS. 1 to 3 is provided in a tunnel, for example, other than the terminal zone for getting on and off the car, which will be described later. It has a narrow cross-sectional shape with left and right guide walls 20 and 21 facing each other with a small interval 1 on both sides, and the left and right guide wheels 13a of the front and rear bogies 3 and 4 are attached to the left and right guide walls 20 and 21, respectively. 13a, 14a, 1
4a and 13b, 13b, 14b, and 14b can be brought into contact at the same time. The running path 22 shown in FIG. 4 is provided within a terminal zone for getting on and off cars, and the left and right guide walls 23 and 24 provided on both sides are spaced apart from each other by a large distance L, that is, approximately twice the above-mentioned small distance l. The left and right guide walls 2 face each other with a certain distance from each other and have a wide cross section.
Auxiliary guide rails 25 and 26 are provided on the outside of the upper portions of the guide rails 3 and 24, and platforms 27 and 28 for getting on and off the vehicle are provided outside of the wide running path 22.

Therefore, the above-mentioned electric transport vehicle 1
To describe the state of running on the narrow running road 19, first of all, when running on the narrow running road 19, the conditions shown in Figs.
As shown in the figure, the left and right guide wheels 13 of the front and rear bogies 3 and 4
a, 13a, 14a, 14a and 13b, 13
b, 14b, 14b are simultaneously the left and right guide walls 20, 2
1, both the front and rear carts 3 and 4 are guided along the same trajectory on the traveling path 19, and the transport vehicle 1 travels with the loading platform 2 facing straight in the direction of travel. Here, as shown in Fig. 4, there is a wide running road 2.
2. When driving on the narrow road 19 in Figure 1,
It exhibits a completely different driving function than when driving on top. In other words, Figure 4 shows the appearance when the electric transport vehicle 1 enters the terminal zone for loading or unloading the automobile A, and at this time, the traveling path 2
The distance L between the left and right guide walls 23 and 24 of the vehicle 1 has been widened, and the auxiliary guide rails 25 and 26 that protrude above the left and right guide walls 23 and 24 are installed. In the front bogie 3, the guide wheels 13a, 13a on the left side in the direction of movement roll into contact with the guide wall 23 on the left side, and at the same time, the auxiliary guide wheels 15a, 15a arranged downward on the left side are on the outside of the auxiliary guide rail 25 on the left side. The rotational engagement engages with the guide wheels 14b and 14 on the right side of the traveling path 22, and the rear bogie 4 is guided on the left side of the traveling path 22.
b comes into rolling contact with the right guide wall 24, and at the same time, the auxiliary guide wheels 16b, 16b disposed downward on the right side come into rolling contact with the outside of the right auxiliary guide rail 26, guiding the right side of the running path 22. It will start running.
In other words, the front and rear carts 3 and 4 travel on trajectories shifted left and right from each other on the wide travel path 22. At this time, since the front and rear carts 3 and 4 are connected to the loading platform 2 via center plate mechanisms 5 and 6, respectively, the loading platform 2 is oblique to the direction of travel, and the front and rear ends 2c are cut off obliquely. , 2d can be stopped facing the platform 27 or 28 for boarding and disembarking provided outside the running path 22 with an extremely small gap, and the automobile A can be placed on the platform 2 from the platform 27 from the rear edge 2d. It becomes possible to get on the cargo platform 2 and get off the vehicle from the front edge 2c of the platform 2 to the disembarking platform 28. In this case, the right guide wheels 13b, 13 of the front truck 3
b and auxiliary guide wheels 15b, 15b, rear truck 4
The left guide wheels 14a, 14a and the auxiliary guide wheel 1
6a and 16a are completely idle, but
The aforementioned guide wheels 13a, 13 on opposite sides of each
a, 14b, 14b and auxiliary guide wheels 15a, 15
a, 16b, 16b, the guiding walls 23, 24, and the auxiliary guiding rails 25, 26, the front and rear bogies 3, 4 can be accurately guided, and the loading platform 2 can move along its front and rear ends 2.
c, 2d always proceed diagonally to face the platforms 27, 28 for getting on and off.
If it is a section where a car A is provided, it is possible to get on and off the car A no matter where it stops.For this purpose, a large number of transport vehicles 1 are stopped within the section of the boarding and alighting platforms 27 and 28, and each car A can get on and off at the same time. You will be able to get on and off the vehicle.

In addition, when the electric transport vehicle 1 travels on the general running path mentioned above, the front and rear bogies 3 and 4 are connected by the loading platform 2 and run on the same rail, so the front and rear bogies 3 and 4 are Run at the same speed as nature. Furthermore, when the loading platform 2 travels in an oblique position as shown in FIG. They are guided by rails 25 and 26 and are mutually connected to the loading platform 2, and run on trajectories that are deviated from each other to the left and right in a state that is shifted back and forth. each trolley 3 and 4 without delay or delay.
Both vehicles can travel at the same speed without having to control their speeds with high precision, and the platform 2 of the carrier vehicle can be maintained at an inclined position at a constant angle with respect to the traveling path.

Here, what kind of track structure should be used to shift the transport vehicle 1 from the running position on the narrow running track 19 shown in FIG. 1 to the running position on the wide running track 22 shown in FIG. 4? The problem is how to use it, but this can be done by gradually expanding the width as shown in FIG. That is, FIG. 5 shows the entrance part 22' to the running road 22 to the terminal zone for getting on and off cars, and the left and right guide walls 2 that continue to the narrow running road 19 outside the terminal zone.
The distance between the ends of 3' and 24' is the same l as that of the running path 19, and it gradually widens from that part to the same large distance L as the left and right guide walls 23 and 24 in the terminal zone. Subsequently, the left and right auxiliary guide rails 25', 26' are arranged so that the distance between them gradually becomes wider so that they continue to the auxiliary guide rails 25, 26 in the terminal zone. With this, the front bogie 3 is placed on the auxiliary guide rail 25' on the left side in the direction of travel.
Auxiliary guide wheels 15a, 15 arranged downward on the left side of
Only a is rollingly engaged, and the right auxiliary guide rail 26'
The auxiliary guide wheels 16b, 16b arranged downward on the right side of the rear bogie 4 are engaged with each other, so that the front bogie 3 continues along the left side of the running path 22, and the rear bogie 4 moves toward the right side. The robot can be guided to the position shown in FIG. 4.

Next, the above-mentioned electric transport vehicle 1 and its running path 1
An example of actual operation using 9 and 22 will be roughly described according to Figure 6 and below. In Figure 6, A indicates a zone other than the terminal zone for getting on and off a car, such as a tunnel zone, and B indicates both ends of the tunnel zone A. Inside the terminal zone and tunnel zone for vehicles located at the entrance/exit (one end is shown and the other end is omitted), there are two lanes 19, 19 with the same narrow width as shown in Figure 1, with two lanes in both directions. The running road 22 is arranged in parallel within the terminal zone, and in anticipation of the busy road, the running road 22 has a branching section 2 for two lanes, one for the inner and one for the inner and outer lanes.
9 and the confluence part 30 so as to continue to the reciprocating routes 19, 19 of the tunnel zone I,
The first half of each of the travel routes 22 and 22 is the arrival route 22.
The latter half of a and 22b are the departure routes 22c and 22d, and the arrival routes 22a and 22b and the departure route 22
c, 22d have left and right guide walls 23, 24 which are gradually widened and have a large interval L as shown in FIGS. 4 and 5, and auxiliary guide rails 2 on both sides.
5, 26, and disembarkation platforms 28, 28 are provided on the left side of the arrival routes 22a, 22b in the direction of travel, and boarding platforms 27, 28 are provided on the right side of the departure routes 22c, 22d in the direction of travel. 27 are provided. Many transport vehicles1 are on these routes.
...... to run. Then, since both the reciprocating paths 19 and 19 are narrow in the tunnel zone I, the transport vehicle 1 travels with the loading platform 2 facing straight in the direction of travel, so the frontal area of the entire vehicle becomes extremely small, and the tunnel etc. The cross-sectional area of can be small. Therefore, the transport vehicle 1 that has traveled on one of the outgoing routes 19 of tunnel zone A... is stopped by a branching mechanism 31, which will be described later, at a branching part 29, so that the arrival route 22a of the traveling route 22 on one of the inner and outer routes of terminal zone A is activated. The cargo platform 2 travels in a state in which it is inclined with respect to the traveling direction as shown in FIG. Then, the transport vehicles 1...... stop from the back of the arrival road 22a section in the order in which they arrive, and in the order of their stops, the vehicles A, which have been loaded on the loading platform 2, are unloaded onto the unloading platform 28. . In order to disembark the vehicle, the driver of the vehicle A drives the vehicle A diagonally from the front edge 2c of the loading platform 2 to the disembarkation platform 28. While doing this, when a suitable number of transport vehicles 1...... accumulate on one arrival route 22a, the branching mechanism 31 switches and transfers the next coming transport vehicle 1 to the other arrival route 22a.
The vehicle A enters the vehicle A, stops the vehicle in order from the back, and exits the vehicle in the same manner as described above. In addition, get off platform 28
is at the same height as the top surface of the loading platform 2 of the transportation vehicle 1, and the diagonal front edge 1c of the loading platform 2 of the transportation vehicle 1 is placed there.
Since these are opposed to each other with a small gap, the car A on the loading platform 2 can freely get off to the unloading platform 28 from the front end of the loading platform 2 by running under its own power, without having to increase the width of the unloading platform 28. The driver can easily change direction as shown by the arrow, get off at the exit platform 28, and travel from the connecting road 32 toward a general motorway (not shown).

Furthermore, when the automobile A gets off from the transport vehicle 1 that has stopped on one of the arrival roads 22a, the transport vehicles 1 sequentially go around the curved road from the arrival road 22a to the one departure road 22c. It runs and is sent away.

In this way, one of the arrival routes 22a becomes empty in preparation for the next arrival of the transport vehicle 1.
When the other arrival route 22b becomes full, the switching mechanism 31 causes the carrier vehicle 1 to enter the one arrival route 22a again, and at the same time, the carrier vehicle 1 on the other arrival route 22b enters the vehicle A. and are sent to the other departure route 22d in order.

The transport vehicle 1, which was alternately sent to the departure roads 22c and 22d, then travels from the general motorway (not shown) to the boarding platform 2 via the connecting road 33.
7, place the car A on the loading platform 2 from the rear end side 2d of the loading platform 2 in the almost reverse procedure of getting off the vehicle, and
In the order in which they were loaded, transport vehicle 1......departure road 22c,
22d and passes through the merging section 30 by a merging mechanism 34, which will be described later, to the other return route 1 of the tunnel zone 1.
I drive to 9.

Here, from the arrival route 22a, 22b to the departure route 22
When forwarding the transport vehicle 1 to destinations c and 22d, the traveling paths 22 and 22 between them are narrowed and the loading platform 2
Connecting road 3 that connects to the above general motorway by facing straight in the direction of travel and reducing the frontal area.
Make it pass under 2,33.

Further, the branching mechanism 31 of the branching section 29 that divides the transport vehicle 1 coming from the traveling route 19 into the traveling routes 22, 22 will be explained with reference to FIGS. 7 and 8. Road 35
A fixed rail 37 is provided above the left guiding wall 36, and a fixed rail 40 is provided above the right guiding wall 39 of the branch path 38 toward the right. A hinge 41 is provided at the starting end of the fixed rails 37 and 40 in the traveling direction.
42 is installed vertically, and these hinges 41, 42
The movable rails 43, 44 connect to the fixed rails 37,
It is attached so as to be rotatable and continuous toward the starting end of 40. These fixed rails 37, 40 and movable rails 43, 44 are each made of lip groove type steel or the like and have a C-shaped cross-section and open on the inside of the running path. Also,
At the lower ends of the hinges 41, 42 are arms 45, 4.
6 is attached, the arms 45 and 46 are connected to each other by a link 47, and the piston cylinder 4
8, and this piston cylinder 4
Arms 45, 46 and hinges 41, 42 are moved by step 8.
The movable rails 43 and 44 are configured to rotate simultaneously in the same direction. For example, as shown in FIG. 7, when the left movable rail 43 is rotated to a normal position near the edge of the running road, the right movable rail 44 is rotated to a position far outside the running track. ing.

When the carrier vehicle 1 enters the branching portion 29 in the state shown in FIG.
15a, 16a, 16a successively move upward and downward within the left movable rail 43 at the normal position as shown in FIG.
With this, the front and rear bogies 3 and 4 are connected to the left guide wheel 13.
a, 13a, 14a, and 14a are connected to the left guide wall 36 while being branched and guided toward the left branch path 35. At this time, the auxiliary guide wheels 15b, 15b, 16b, 16b on the right side in the direction of movement of the front and rear bogies 3, 4 are completely free because the movable rail 44 on the right side has rotated to a far away position. I am not guided in any direction. Therefore, the transport vehicle 1 is smoothly guided to the left branch road 35 and runs. Here, if the piston cylinder 48 is operated to rotate the left movable rail 43 far outward and to rotate the right movable rail 44 to the normal position, the transport vehicle 1 traveling from now on will be The right side auxiliary guide wheels 15b, 15b, 16b, 16b of the front and rear bogies 3, 4 are engaged with the movable rail 44 on the right side and proceed, and the carrier vehicle 1 is branched and guided towards the right side branch road 38. I get to go.

Next, in FIG. 9, the merging mechanism 34 of the merging section 30
Specifically, a fixed rail 51 is provided above the left guide wall 50 of the merging path 49 coming from the left side in the direction of travel, and a fixed rail 54 is provided above the right guide wall 53 of the merging path 52 coming from the right side in the direction of travel. It is being Hinges 55, 56 are vertically attached to the terminal ends of the fixed rails 51, 54 in the traveling direction, and movable rails 57, 58 are connected via the hinges 55, 56.
are attached to the terminal ends of the fixed rails 51, 54 so as to be rotatable and continuous. These fixed rails 5
1, 54 and the movable rails 57, 58 are made of lip groove type steel or the like and have a C cross-sectional shape, similar to the foregoing branch portion. Further, arms 59, 60 are attached to the lower ends of the hinges 55, 56, and the arms 59, 60 are attached to the lower ends of the hinges 55, 56.
0 are connected to each other by a tension spring 61, and the arms 59, 60 are connected by this spring 61.
and movable rails 57, 5 via hinges 55, 56.
8 are both rotatably held at their normal positions near the edge of the running path.

However, I suddenly saw merging road 49 on the left side of the direction of travel.
When the transport vehicle 1 comes running, the auxiliary guide wheel 15 on the left side in the direction of travel of the front and rear carts 3 and 4 of the transport vehicle 1
a, 15a, 16a, 16a advance in rolling engagement with the upper and lower parts of the fixed rail 51, enter the movable rail 57 on the left side, and at the same time, the left guide wheels 13a,
13a, 14a, and 14a also move in tandem along the left guide wall 50, thereby guiding the carrier vehicle 1 to pass through the merging section 30. In addition, at this time, the guide wheels 13b, 13b, on the right side in the traveling direction of the front and rear bogies 3, 4,
14b, 14b are temporarily free, but soon they are guided to the right guide wall 53 of the merging section 30, and the right auxiliary guide wheels 15b, 15b, 16b, 16b of the front and rear bogies 3, 4 The movable rail 58 on the right side is rotated outwardly against the spring 61 so as to be pushed away, and it passes without any problem. Conversely, when the transport vehicle 1 comes from the merging path 50 on the right side of the traveling direction, the right side auxiliary guide wheels 15b, 15b, 16b, 16b of the front and rear trucks 3, 4 are connected to the fixed rail 5.
4. The left auxiliary guide wheels 15a, 15a, 16a, 16a are guided by rolling engagement in the movable rail 58.
passes by pushing aside the left movable rail 57. In this way, no matter which side the transport vehicle 1 comes from at the merging part 30, it is easily guided to the merging part 30 and can run smoothly. Although this merging mechanism 34 holds both movable rails 57 and 58 with one spring 61, it is also possible to use independent compression springs 61a and 61b, respectively, as schematically shown in FIG. .

As explained above, in the device of the present invention, the front and rear carts of the electric transport vehicle can be guided along the right or left guiding wall, thereby minimizing the frontal area on a general running road. By reducing the cross-sectional area of tunnels, etc. through which electric transport vehicles pass, the cost of tunnel construction can be reduced.In the terminal area, the front and rear bogies pass on different trajectories, making the loading platform slanted and installed toward the vehicle side. Cars can be loaded and unloaded from the drop-off or pick-up platform extremely easily, the structure of the terminal section is simplified, the process can be carried out in a small space, and the time required to board and unload a car is extremely short. Therefore, operational efficiency is extremely high, resulting in an overall economical system.
