Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branching system for an ultra-high-speed railway for performing high-density transportation.

[0002]

2. Description of the Related Art Conventionally, transportation carriers (vehicles) traveling on railroads or roads are separated from each other by a predetermined distance before and after to ensure safety. In recent years, in order to increase the transport density, efforts have been made to increase the speed of transport carriers, to reduce the distance between the front and rear carriers by computer control, and to improve transport efficiency.

[0003]

[Problems to be solved by the invention] However, in the case of railways, for example, although automated ticket gates and ticket gates and computerized operation management are performed, technological innovation has not yet been thoroughly implemented in other parts. It is. As a result, the congestion of rush hour is not resolved even in the case of overcrowding on railway lines in large cities, and traffic congestion is becoming routine on roads in the center and surrounding areas of the city. No solution has been proposed to drastically improve this situation.

On the other hand, the development of a linear motor car using both the superconducting system and the normal conducting system has been successfully developed. For this purpose, application to a suburban line (including an airport line) or a metropolitan line (for example, a bullet train) is proposed. However, application to intra-urban routes has not yet been studied, and no comprehensive study of a nationwide ground transportation system based on a linear motor car has been made so far.

[0005] Of the conventional ground transportation systems, railways and motorways have the following advantages and disadvantages, respectively, but these disadvantages make it difficult to solve the above-mentioned urban traffic problems. a. While railroads have the advantage of space-efficient mass safe transport with good space efficiency, they have the disadvantages of time loss due to stopping and transferring at each station, restrictions on the distance between stations, and low speed. b. The motorway has the advantage of being able to select an arbitrary route, but has the disadvantages of poor space efficiency per person, time loss due to stoppage of traffic lights, and low speed. Among them, the disadvantage of low speed is realized by a magnetic levitation type linear motor car capable of realizing a high speed of 200 to 500 km / h, so that this disadvantage can be greatly reduced and approached to that of an aeronautical system. However, even if high-speed performance is realized, stopping large vehicles at each station not only prevents loss of stopping time, but also avoids the contradiction that unless the distance between stations is long, the advantage of high speed cannot be used. Can not do.

In order to solve the above-mentioned problems, a large number of small magnetically levitated linear motor cars are used to drive the vehicle unattended to a destination in an unmanned operation (except when manned for safety reasons) by completely computer control. What is necessary is just to build a mass transit urban transport network. Although the details of the concept are omitted, unstopped traveling not only eliminates the time loss associated with stopping at each station, which was a drawback of the conventional railway system, but also the route from the parking lot at the boarding point to the route (trackway). By making the shortest route to the destination parking lot go straight by computer command while transiting, the loss of transfer time can be eliminated and the restriction on the distance between stations can be eliminated. However, the greatest technical difficulty in realizing such a transportation system is the route branching method. Hereinafter, the reason will be described in detail.

FIG. 6 is a front sectional view of an example of a magnetic levitation type linear motor car using a superconducting system according to the prior art. Generally, in a superconducting magnetic levitation type linear motor car, the maximum speed is about 500 km / h, but the vehicle floats at 150 km to 200 km / h.
h, and when the vehicle is stopped or running at a low speed, no levitation force is generated, and the running is performed exclusively through the supporting auxiliary wheels 12 and the guiding auxiliary wheels 10. In the figure, reference numerals 20 and 20 'denote superconducting coils for levitation, propulsion and guidance, which are vertically mounted on both sides of a bogie 9 supporting a vehicle V by an air spring S, and 1 and 1' are levitations having the same shape and dimensions.・ Conductor coil for both propulsion and guidance
The conductor coils 1, 1 'connect the upper coils 2, 2' and the lower coils 3, 3 'in a figure eight shape, respectively.
It is composed of a closed circuit (null flux connection) connected to each other via connection lines 4 and 5 (two reciprocations). The conductor coils 1, 1 'are spaced apart from each other by a predetermined distance along the vehicle traveling direction on both inner sides of the guide side wall 14 of the track path 13 having a U-shaped cross section so as to be electromagnetically coupled to the superconducting coils 20, 20'. , Are arranged vertically and continuously. that time,
When the vehicle V is seated on the wheel running path 15 of the track 13 via the auxiliary wheels 12, the superconducting coils 20, 2
The vertical center of 0 'and the vertical centers of the conductor coils 1, 1' are set to be on the same horizontal line.
A three-phase or multi-phase frequency-controlled propulsion power supply (not shown) is connected to the connection lines 4 and 5. The operation principle of the superconducting magnetic levitation type linear motor car according to the related art configured as described above is as follows.

When the vehicle V is traveling at low speed on the wheel running path 15 via the supporting auxiliary wheels 12, the positional relationship between the superconducting coils 20, 20 'on the vehicle and the conductor coils 1, 1' on the ground is This is set as described above. In this positional relationship, no sensitive current is induced in the conductor coils 1, 1 'due to the electromagnetic induction of the magnetic flux of the superconducting coils 20, 20'.
There is no levitation force. At the time of levitation traveling with the support auxiliary wheel 12 of the vehicle V retracted, the vertical center of the superconducting coils 20, 20 'shifts below the vertical center of the conductor coils 1, 1', and the upper coil 2, 20 '. A difference is generated between the magnetic flux linking 2 'and the lower coils 3, 3', and a current is induced. At this time, the lower half of the figure-eight coil (lower coil 3, 3 ') has the same polarity as the superconducting coil 20, 20', so that the lower coil 3, 3 'and the superconducting coil 20,
A repulsive force is generated between the repulsive force and the pressure 20 '. On the other hand, the upper half of the figure 8 coil (upper coil 2, 2 ') has a lower coil 3,
A current flows in a direction opposite to that of 3 ′, and the superconducting coils 20, 20 ′
, A suction force is generated. The repulsive force and attractive force generated between the superconducting coil on the vehicle and the conductor coil on the ground as described above cause the superconducting coil 2 on the vehicle to move.
A levitation force is generated to return 0 and 20 'upward, and the vehicle is stabilized at a position balanced with the weight of the vehicle.

When the vehicle V is located at the center of the track 13, the conductive coils 1, 1 ′ on the ground are arranged symmetrically with respect to the longitudinal center line of the track and opposing upper coils 2, 1. 2 'and the lower coils 3 and 3' are connected (null flux connection) via the connection wires 4 and 5 as described above to form the conductor coils 1 and 1 '. 0, and no induced current is generated in the conductor coils 1 and 1 '. However, if the vehicle V is displaced in either direction during the levitating operation, a difference is generated in the magnetic flux linking between the upper coils 2 and 2 'and between the lower coils 3 and 3', and a current is induced. Therefore, the superconducting coils 20, 20 'on the vehicle
As a result, a guiding force for returning the vehicle V to the center is generated. In the drawing, reference numeral 10 denotes a guide auxiliary wheel pivotally connected at one end to the other end of the shaft 11 fixed to the vehicle V, and assists the guide while rotating along the side surface of the guide side wall 14 of the track 13.

The conductor coils 1 and 1 'are continuously formed at predetermined intervals on both inner sides of the guide side wall 14 of the track path 13 having a U-shaped cross section at a predetermined interval in the vehicle traveling direction. An upper coil 2, 2 'and a lower coil 3, 3' are arranged and connected via connection lines 4, 5, and a three-phase or polyphase power supply (not shown) is connected via connection lines 4, 5. )
When an AC voltage whose frequency is controlled is supplied from
An alternating current in the same direction flows through each of the coils 2, 3, 2 ', 3', and magnetic fields (N pole, S pole) are generated alternately. On the other hand, in the superconducting coils 20 and 20 'on the vehicle V, the north pole and the south pole are alternately arranged, so that the attractive force between the north pole and the south pole is
A repulsive force is generated between the N-pole and the S-pole, and suction is generated alternately between each coil on the ground and the superconducting coils 20, 20 'on the vehicle V according to the principle that the rotary induction motor is linearized. A propulsive force for moving the vehicle V forward is generated by the force and the repulsive force.

FIG. 7 is a front sectional view of an example of a magnetic levitation type linear motor car using a normal conduction system according to the prior art. Generally, in a normal-conduction type magnetically levitated linear motor car, the maximum speed is about 200 km / h, but since the vehicle V is levitated even in a stopped state, no auxiliary wheels are required. In the figure, reference numerals 21 and 21 'denote floating / guide and normal conducting coils horizontally mounted on both sides of a bogie 9 supporting a vehicle V with an air spring S, and 6, 6' denote track paths 13.
Levitation and guide rails horizontally mounted on both inner sides of the left and right guide side walls 14, and as shown in the figure, the levitation and guide rails 6 and 6 'are levitation and guide / normal conductive coils 2.
It is located above and opposite to 1, 21 ', and 7, 7'.
Reference numerals 8 and 8 'denote propulsion reaction plates horizontally mounted on both insides of the right and left guide side walls 14 of the track 13 and are shown in the figure. As shown, the propulsion reaction plates 8, 8 'are located opposite to and below the propulsion normal conducting coils 7, 7'. The operation principle of the conventional normal-mode linear motor car constructed as described above is as follows.

Floating / Guide Normal Conducting Coil 21, 21 '
A current is made to flow to the electromagnet to form a normal electroconductive magnet, and the rails 6, 6 'for both floating and guiding are attracted from below. The reaction force of the suction becomes a floating force that lifts the vehicle V. At this time, a current flowing through the normal conducting coils 21 and 21 'is controlled by a gap sensor (not shown) so that the attracted normal conducting coils 21 and 21' do not contact the rails 6 and 6 '. Is maintained.

At this time, if the position of the vehicle V deviates from the center of the track 13, the positions of the normal conducting coils 21, 21 ′ and the rails 6, 6 ′ are also shifted to increase the gap between the two. Controls the current to the normal conducting coils 21 and 21 'to increase, the attraction force increases, and a guide force is generated in a direction to bring the position of the vehicle V closer to the center, thereby correcting the displacement of the vehicle V.

When a moving magnetic field is generated by passing a moving magnetic field generating current from a power source on the vehicle V to the propulsion normal conductive coils 7, 7 ', an aluminum reaction plate 8, 8 on the rails 6, 6' is formed. The eddy current flows through the ′, and a thrust for moving the vehicle V forward is generated according to the principle that the rotary induction motor is linearized.

FIG. 8 or FIG. 9 is generally considered as the orbital path branching method of the magnetic levitation type linear motor car as described above. FIG. 8 is a plan view of an example of a track branching method of a magnetic levitation type linear motor car using a superconducting method or a normal conducting method according to the prior art, and shows a concrete girder of a track on which a vehicle travels (track 13 shown in FIG. 6). A part of the guide side wall 14 and a part of the wheel running path 15) is cut off to form a switch 35, which is turned around a part of one end 36 thereof. One end 36 of the switch 35 is connected to a main line 37, and the other end 38 is connected to a main line 39 or a branch line 40. The switching method shown in Fig. 8 relies on the mechanical movement of heavy concrete girders to perform the switching operation, and is not suitable for high-speed switching required for high-density operation with short intervals between trains or automation requiring high reliability. Has disadvantages.

FIG. 9 is a plan view of another example of a conventional magnetically levitated linear motor car using a superconducting type, which is a track branching method of a linear motor car. Switching to low-speed traveling according to FIG. 6), a switch 42 is provided in the middle of the main line guide rail 41 provided on the wheel traveling path 15 (FIG. 6), and switching operation to the branch line guide rail 43 is performed. I have. Guide side walls 14 on both left and right sides of the turnout (FIG. 6)
Has been removed. The branching method shown in FIG. 9 switches to low-speed traveling at the branching point, preventing high-speed operation.
It has a drawback that it is not suitable for automation requiring high reliability because it relies on the mechanical movement of the guide rail by a switch machine.

The method of branching the track path of a magnetically levitated linear motor car shown in FIGS. 8 and 9 in a horizontal plane is a track path composed of a heavy object such as a concrete girder or a guide rail having a delicate shape. However, it has a drawback that it is not suitable for high-speed operation and automation, and does not satisfy the requirements for realizing the traffic system as described above. This is especially true when the switch is operated manually.

Accordingly, an object of the present invention is to provide a branching system for an ultra-high-speed railway which solves the following problems in the prior art. (1) A branching method that does not require mechanical movement of the track path or guide rails by performing switching vertically instead of switching within a horizontal plane. (2) A mechanism that is not suitable for high-speed switching and automation, such as the mechanical movement of a track path consisting of a heavy object such as a concrete girder or a guide rail with a delicate shape or mechanical operation by hand, but high-speed switching and automation. Branching system with a mechanism suitable for (3) Instead of switching to low-speed traveling at a branch point, a branching method is used in which switching can be performed while traveling at high speed.

[0019]

In order to achieve the above object, an invention according to claim 1 is a branching system for an ultra-high-speed railway for branching a railway vehicle from a main line during an ultra-high-speed operation,
The main track running track, the branch track running track, and a vehicle traveling on the main track running track and the branch track running track, the main track running track has an opening wider than the width of the vehicle. The branch track traveling path is provided at a position opposed to the path, and both ends are within the opening, and at the transition portion from the main line to the branch line, the arc gradually loosens downward from the main line traveling path as it proceeds. The vehicle has a first hydraulic cylinder and a first arm having a lower arm and a lower arm extending and contracting from the width of the main track track to a width smaller than the inner space of the opening. A main line running means provided opposite to each tip of both arms of the telescopic mechanism and each inner side surface of the guide side wall of the main line track path, further comprising: The telescopic mechanism is located below,
A second hydraulic cylinder and a second telescopic mechanism having both arms extending and contracting from a width wider than the branch line traveling orbital path to a width of the branch line traveling orbital path; Branch line running means are provided opposite to both ends of both arm portions and both outer side surfaces of the center wall of the branch line running track path, respectively. When the vehicle is running on the main line, the first line is provided. The two arms of the first telescoping mechanism extend in a state where both arms of the second telescoping mechanism extend to the main-track traveling orbital path, and the two arms of the second telescopic mechanism extend wider than the branch line traveling orbital. Each part of the main line running means provided at each end of the main line and each part of the main line running means provided on each inner side surface of the guide side wall of the main line track path cooperate with each other to levitate, propell and guide the vehicle. In the section where the vehicle transitions from the main line to the branch line, it extends to a wider width than the branch line traveling track during main line travel The arm portions of the second telescopic mechanism are reduced to the width of the branch line traveling orbital path, and the branch line traveling means provided at each end of both arm portions of the second telescopic mechanism and the branch line traveling. The respective parts of the branch line running means provided on both outer surfaces of the center wall of the orbital path for each other cooperate with each other to lift the vehicle,
While the vehicle is being propelled and guided, and the arms of the first telescoping mechanism, which has been extended to the main track running path during main road running, are reduced to a width smaller than the inner space of the opening, the vehicle is moved along the branch line running track. In the section where the vehicle transitions from the branch line to the main line, the vehicle reverses the above process, and the vehicle moves up and down from one main line to the branch line and from the branch line to the other main line. Then, the transfer from one main line to another main line is completed.

Therefore, in the present invention, the method of branching the track of the magnetically levitated linear motor car in a horizontal plane as in the prior art is not adopted, and the vehicle is provided with a means for traveling on the main line,
The main line running means and the branch line running means have a structure in which the length (width) can be freely expanded and contracted. At the transition from the main line to the branch line, the main line travel track path as a track path branching device is three-dimensionally intersected so as to gradually move downward from the main line as the vehicle traveling on the track path advances. A track track for branch line travel is provided. Further, in the transition from the branch line to the main line, there is provided a branch line traveling trackway which three-dimensionally intersects as the vehicle traveling on the branch line gradually approaches the upper main line from below as the vehicle proceeds. Note that the branch line traveling track path is sufficiently narrower than the main line traveling track path and intersects the vicinity of the center of the main line traveling track path.

As described above, in the prior art, since the switching operation is performed by relying on the mechanical movement of a heavy concrete girder or guide rail, high-speed switching or high reliability required for high-density operation with a short interval between trains is required. It is not suitable for automation which requires high reliability, it is not suitable for automation which requires high reliability because it relies on mechanical operation of a switch, and switching to low speed running at a branch point hinders high speed operation. Was.

Therefore, the present invention does not employ the method of branching the track of a magnetically levitated linear motor car in a horizontal plane as in the prior art, and vertically shifts from a main line to a branch line and from a branch line to another main line. In this method, the switching operation is not performed by relying on the mechanical movement of a heavy object such as a concrete girder.

In the vehicle of the present invention, at the entrance of the transition section from the main line to the branch line, the main line traveling means extends to the main line traveling track, and the branch line traveling means is connected to the branch line traveling track. Since the vehicle is extended to a wider width, the vehicle travels only by the main road traveling means. At this time, since the branch line running means extends to a wider width than the branch line running track, it does not come into contact with the branch line running track. As the traveling section progresses, the branch line traveling means decreases in width to the width of the branch line traveling track, and the width of the main line traveling means becomes shorter than the inner space between the openings of the main line traveling track. When passing through the transition section and entering the branch line, the role of the main line traveling means ends, and the vehicle travels only with the branch line traveling means, and the vehicle gradually moves downward from the main line on the branch line traveling track. Come away. At this time, since the mainway running means is already shorter than the inner space of the opening of the mainway running track, it does not come into contact with the mainway running track.

As described above, according to the first aspect of the present invention, the main line traveling means and the branch line traveling means are provided at the distal ends of both arms of the first telescopic mechanism and the second telescopic mechanism, respectively. It has a structure that allows the (width) to expand and contract freely. When traveling on the main line, the main line traveling means extends to the main line traveling track, and when traveling on the branch line, the branch line traveling means reduces to the width of the branch line traveling path. It is supposed to. By the way, the content of claim 1 excluding the above-mentioned telescopic structure of the branch line traveling means is known from Japanese Patent No. 1900792. However, the invention of Japanese Patent No. 1900792 includes a telescopic structure of the main line traveling means, but does not include a telescopic structure of the branch line traveling means. Therefore, Patent No. 19
In the content of the invention of No. 00792, the length of the branch line traveling means is fixed to the width of the branch line traveling track, and when the main line is shifted to the branch line, the branch line traveling means and the branch line traveling There was a risk of collision of the orbital route. The invention of claim 1 includes the first invention included in the invention of Japanese Patent No. 1900792.
In addition to the telescopic mechanism described above, a second telescopic mechanism having an arm that expands and contracts on both sides from the width wider than the track path for branch line travel to the width of the track path for branch line travel is provided. By providing the branch line running means provided to be opposed to both the front end and both outer side surfaces of the center guide wall of the branch line running track path, the length of the branch line running means is also configured to be expandable and contractable, as described above. This eliminates the risk of collision between the branch line traveling means and the branch line traveling track path when shifting from the main line to the branch line. In Japanese Patent No. 1900792, there is no description about the mechanism of the telescopic structure of the means for traveling on the main line, but the invention of claim 1 is based on the main line provided at each end of both arms of the first telescopic mechanism. Hydraulic cylinders are used as the extendable and retractable mechanisms of the length of the branch line traveling means provided at the respective distal ends of both arms of the traveling means and the second telescopic mechanism. The hydraulic cylinder has a main line running means provided at each tip of both arms of the first telescopic mechanism and a branch line provided at each tip of both arms of the second telescopic mechanism due to the following features. It is suitable for high-speed switching and automation as an extendable mechanism of the length of the traveling means. 1) It is easy to control the speed, direction, and force of the control target. 2) Small size, light weight, high power and good responsiveness. 3) Stable speed control over a wide range. 4) Easy to combine with electrical equipment.

According to a second aspect of the present invention, when one end of the branch line is at the end point, the transition from the main line to the branch line is performed downward so that the vehicle enters the branch line from the main line to the end point, and When one end is the starting point, the transition from the branch line to the main line is performed upward so that the vehicle enters the main line from the starting point via the branch line. As described above, in the present invention, the transfer of vehicles from one main line to a branch line, from a branch line to another main line is performed up and down, and the transfer from one main line to another main line is completed. In the case of transition from the main line to the branch line, the transition is performed downward, and when the transition is performed from the branch line to the main line, the transition is performed upward. The invention of claim 2 is
When one end of the branch line is the end point, it shifts downward from the main line to the branch line, and when one end of the branch line is the starting point, it shifts upward from the branch line to the main line. Things.

According to a third aspect of the present invention, optical position detecting devices D and D 'are provided at the entrance and the exit of the transition section from the main line to the branch line and from the branch line to the main line, respectively. As described above, in the present invention, according to the position of the vehicle traveling in the transition section, the length of the main line traveling means provided at each end of both arms of the first telescopic mechanism and the second telescopic The length of the branch line running means provided at each end of both arms of the mechanism is expanded and contracted. The optical position detectors D and D 'detect the time at which the vehicle passes through the entrance and exit of the transition section from the main line to the branch line and from the branch line to the main line, and adjust the travel time of the vehicle to the transition section. For calculating the position information of the vehicle running on the vehicle.
