Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a track simple articulated branching device for a normal conductive magnetically levitated vehicle that travels by a linear motor while levitating and guiding the vehicle using the attractive force of a normal conductive electromagnet.

Many types of branching devices for normally conducting magnetically levitated vehicles have already been proposed before the present invention. Among them, this patent application was first proposed in 1973.
−113340, a joint flexible branching device for a track for a normal conductive magnetically levitated vehicle, connects a large number of short joint tracks jointly so that their necks touch each other, and only the left and right guide rails are flexible. As it is long and has a structure that can be deformed in a curved manner, the left and right guide rail regulating device that is passed between each joint track allows the guide rail to be curved to suit bifurcation in two directions such as right, left, or straight. Even if a large lateral force is applied, the guide rail can maintain its linear shape accurately and a stable branching action can be obtained. However, with the device of the earlier application mentioned above, it is impossible to perform branching operations in many directions such as 3 directions and 4 directions, and it is very difficult to perform branching operations in many directions at once, such as in a garage. Unfortunately, there was a problem that made it impossible to apply it to convenient locations.

The present invention was developed in view of the above circumstances, and its purpose is to provide a simple type of articulated branch that can branch in many directions, such as 3 or 4 directions, in places such as garages where vehicle speed is low and large guiding forces are not required. The purpose is to provide equipment.

Before providing a detailed explanation of the present invention, the concept of a normal conductive magnetic levitation vehicle will be explained using a basic cross section of a normal conductive magnetic levitation vehicle shown in FIG.

In the figure, 1 is the vehicle body, 2 and 3 are levitation electromagnets, 4 and 5
are the left and right guiding electromagnets, and these electromagnets 2, 3,
4 and 5 face the levitation rails 6 and 7 and the guide rails 8 and 9 of the orbit, respectively, and a gap sensor (not shown) detects the gap between each electromagnet and each rail, and if necessary, detects the acceleration. The movement of each electromagnet is detected by a sensor, and the current of each electromagnet is controlled by a control device (not shown) so that the electromagnet is levitated, guided and held with a certain gap.
These electromagnets are attached to the bogie frame 10, and are adapted to receive the load of the vehicle body by air springs 17 and 18. Solid tires 11 and 12 are attached to the front and rear ends of the bogie frame 10, and when the levitation electromagnet is demagnetized, the solid tire running tread 1 on the track
3 and 14 to support the weight of the vehicle body. Moreover, on the inner lower surface of the bogie frame 10,
SLIM primary (single side linear induction motor primary) 15 was installed on the beam 19 that connects the rails for left and right guidance of the track, etc.
It faces the SLIM secondary conductor 16 and is designed to obtain the thrust necessary for running and decelerating the vehicle. The beam 19 is now fixed on the girder 20 with a relatively short pitch. The beams 20 are supported via supports 21 on piers 22 provided at regular intervals.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 6.

Figure 2 shows the simple joint flexible branching device of the present invention.
An explanatory diagram for performing a direction branching action is shown, in which 23 indicates a track on the single track side, and 24, 25, and 26 indicate tracks in three directions that branch. Rails 30a, 30 are provided between this single track side track and the branch track in three directions.

7a, 27b...27d are the respective support stands 28a, 2
8b......A lateral movement mechanism (not shown) provided in 28d bends and moves along a broken line to freely connect any of the branch tracks 24, 25, and 26 in three directions to the single track side track 23. It's getting old. In this case, a mechanism is required in which each joint short track 27a, 27b...27d moves so as to connect with the branch track in three directions, stops, and then locks accurately at that position. As the mechanism, a locking device of a known structure that has been widely used in the past may be used, and since it is outside the scope of the present invention, detailed structural explanation will not be given, but the explanation will proceed assuming that a locking device is provided as a matter of course.

Here, the configuration of the joint short trajectory and the relationship of the left and right guide rails to the joint short trajectory will be described with reference to FIGS. 3 and 4. First, 27b, 27c in Fig. 3,
As shown at 27d, each joint short track is connected to a connecting pin 29.

As shown at 27c in FIG. 4, the joint short track has a cross-sectional form that is approximately the same as the general track shown in FIG. 1, except that it is mounted on a support platform 28c that can run on rails 30c. . That is, the short beam 20a is fixed on the support stand 28c, and the beam 1 is placed on the short beam 20a.
9a is fixed, floating rails 6a and 7a are fixed to the lower part of both ends of the beam 19a, and solid tire running treads 13a and 14a are fixed to the upper part,
In addition, a SLIM secondary conductor 16 is placed at the middle upper part of the beam 19a.
a is fixed, and these short girders 20a, beams 19a,
The floating rails 6a, 7a, the solid tire running treads 13a, 14a, and the SLIM secondary conductor 16a are integrally moved together with the support base 28c on the rail 30c in either the left or right direction. Here, the left and right levitation rails 6 of the above-mentioned short joint tracks
a, 7a and solid tire running treads 13a, 14
a and guide pins 32 and 33 by connecting them vertically.
As shown in FIG. 3, two right and left guide pins 31a and 31b are fixed at a distance of about half the length of the short track, and left and right guide rails 31a and 31b are installed so as to abut on the outside of these left and right guide pins 32 and 33. ing. The left and right guide rails 31a, 31b are arranged separately from the short joint tracks, and the left and right guide rails 31a, 31b are continuous with the entire length of the plurality of short joint tracks 27a, 27b...27d, respectively. The left and right guide rails 31a and 31b are arranged in brackets 38a and 38 to maintain a constant distance from each other.
b and links 39 at multiple locations, and the brackets 38a, 38b are slidably mounted on sliding pieces 46a, 46a fixed to the upper surfaces of the floating rails 6a, 7a, as shown in FIG. and each joint short trajectory 27a, 27b......27
As d moves in the left and right direction, it is guided from the inside by guide pins 32 and 33, two on each side, and elastically curves. Here, the ends of the left and right guide rails 31a, 31b connected to the three-way branch tracks 24, 25, 26 are fixed metal fittings 36, 37 that fit into the guide pins 34, 35 of the joint short track 27d. has been fixed through.

Moreover, on the other hand, the above-mentioned left and right guide rails 31a, 31b
The end portion on the side connected to the single-wire side track 23 has a structure shown in FIGS. 5 and 6. Here, since they are bilaterally symmetrical and have the same structure, only the end structure of the right guide rail 31a is illustrated and the left side is omitted. As shown in FIG. 5, the guide rail 31a
A short guide rail 40b is connected to the end of the hinge metal fittings 41e and 41d, and the hinge metal fitting 41
A short guide rail 40a is connected via c and 41b. On the other hand, 43 is a guide rail of the single track side track 23, and a guide fitting 44 having a guide groove 45 protrudes from this guide rail 43, and the hinge fittings 41b, 41c and 41d of the short guide rails 40a, 40b, 41e and guide rollers 42a, 42b, 42c held by the end metal fittings 41a, respectively.
is slidably fitted into the guide groove 45. Note that the guide groove 45 is curved in the vicinity of the guide rail 43 and formed in a substantially slanted shape toward the center of the track. Here, Fig. 5 shows a state in which the short guide rails 40a and 40b are connected to the guide rail 43 of the single track side track, and the guide rail 31a is further connected, and in the case of Fig. 6, the short guide rail 43 is connected to the guide rail 43 of the single track side track. 40a is stored near the center of the track along the guide groove 45, and is used as the guide rail 4 of the single track side track.
3 is the guide rail 31 via the short guide rail 40b.
It shows the state where it is connected to a. In such a structure, two short guide rails 40a and 40b are used.
are both stored inside the track in the guide groove 45, and the guide rail 43 can be connected to the guide rail 31a.

To describe the operation of the branching device having the above-mentioned configuration, each of the support stands 28a, 28b...28d runs on the rails 30a, 30b...30d, and each joint short track 27a, 27b...27d bends and moves in a broken line. At this time, those short orbits 27a, 2
Connecting pins 29a, 29 connecting 7b...27d
Joint short tracks 27a, 27b, in which left and right guide pins 32, 33, and 33, which are arranged at approximately half the spacing between pins b...29d, are bent in a polygonal manner.
...They will be arranged along the curved line of 27d.
Here, since the left and right guide rails 31a and 31b are held at a constant distance from each other by the brackets 38a and 38b and the link 39, they are forced to move along the left and right guide pins 32 and 33. It is curved to form a smooth curved line. In this case, the guide rails 31a and 31b have a considerable thickness in order to allow the flux of the guide electromagnet to pass through, but since the radius of the curve is large, the force that causes them to curve along the track is not very large. Not,
Moreover, the guide electromagnet is subjected to distributed load and does not reach a force that would cause abnormal deformation between the guide pins 32 and 33, which are arranged at short intervals, so that a smooth curve shape can be easily maintained. Furthermore, when the branching device is switched to the right or left, the required guide rail length changes between the inner and outer rail sides of the curve. In this case, in the case of a three-way branch, it is necessary to adjust the length of the guide rail in three steps on each side, and the length adjustment is performed using two short guide rails 40a and 40b, as shown in Figures 5 and 6.
By moving forward and backward along the guide groove 45, the length of the guide rail at the required stage can be obtained. In this way, the guide rails 31a, 31b have a large number of joint short tracks 27.
a, 27b, 27c, and 27d can each be constructed of a single long piece, and the short guide rails 40a, 40b can advance or retreat between the single track side guide rail 43 depending on the required shaft length. Therefore, even if the branching device is switched to the right or left, there will not be a large gap at the joint of the guide rail, and the gap sensor will not receive an erroneous signal at the joint of the track, which will improve the guidance control. can be performed extremely stably.

FIG. 7 is an explanatory diagram showing another embodiment of the present invention,
In this case, the left and right guide rails 31a', 31b' are divided rails 31c, 31d, 31e, 31f, 31g having approximately half the length of the short joint tracks 27b, 27c, 27d.
...... connected by a hinge 47, and the left and right divided rails 31c, 3 in the middle
1c and 31e, 31e to brackets 38a, 3
8b by a link 39. In this way, it is not possible to construct a guide rail with a smooth curve as shown in FIG. 3, but the short joint tracks 27b, 27c,
It is possible to construct a polygonal broken linear guide rail that connects each of the 7d tracks at an angle that is half the fold angle formed by each track, thereby eliminating the force required to bend the guide rail against elasticity. Therefore, less driving force is required when operating the branching device. Furthermore, since the vehicle runs along the guide rails 31a' and 31b' which are bent into a polygonal shape, the riding comfort is not good to some extent, but it can be used without any problem for low-speed running in a garage or the like. In this case as well, a plurality of short guide rails as shown in Figs. 5 and 6 are arranged at the ends of the left and right guide rails 31a' and 31b' so that they can move forward and backward to adjust the required length. conduct.

As described above, according to the present invention, the necessary guide rail shape can be obtained without using a special mechanism with a branching device that bends and moves a large number of joint short tracks in a broken line shape. It is possible to provide features that could not be obtained conventionally, such as the ability to branch in three or more directions.
