Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a scissor crossing device constructed using a branching device for a normally conducting magnetically levitated vehicle.

Many branching devices for normal conductive magnetically levitated vehicles have been proposed in the past, and they can be broadly classified as follows.

a Vehicle-mounted branch type branching device In this case, there are no moving parts on the track side, and the vehicle side has a main electromagnet (for levitation and guidance) and an auxiliary electromagnet (for levitation and guidance), and can branch to the right or left. The feature is that the electromagnets are selectively switched and controlled, and branch control is performed from on-board. However, this requires extremely weak electromagnetic control switching while passing through a branch, requires extremely advanced technology and reliability when used in train formations, and requires an electromagnet that can support vehicles even if it is rated for a short time. Even simple branching has such problems, as it increases vehicle weight and construction costs. This therefore precludes application in complex scissors crossings.

b Non-deformable track moving type branching device This method is also seen in monorail branching devices, etc., and is a method of configuring the track alignment by moving the non-deforming track laterally. When we actually drew this up, we found that the track for the normal conductive magnetically levitated vehicle was quite complex, so it was quite difficult to construct, and the branch area required quite a large area, making it difficult to construct a scissors crossing. It is difficult to do so.

c Flexible track type branching device There is a method of constructing a branching device by elastically deforming the entire branching device, but this method is further divided into a completely flexible branching device in which the girder itself is also curved, and a fully flexible branching device in which the girder itself is curved. There are two types of joint flexible branching devices that curve only the rail portion on which the vehicle travels. Of these, the latter method of curving the orbit itself requires less land and has the possibility of forming a scissor crossing. Therefore, we will explain the case in which this flexible track type branching device is actually applied to scissor crossing for a normal conductive magnetic levitation vehicle.Before that, we will provide an outline of a commonly used normal conductive magnetic levitation vehicle using Fig. 1. The configuration will be explained. That is, in the figure, 1 is a vehicle body, 2 and 3 are levitation electromagnets, and 4 and 5 are guide electromagnets, which face levitation rails 6 and 7 and guide rails 8 and 9, respectively. Then, each electromagnet 2, 3, 4, 5 and each rail 6,
7, 8, 9, and if necessary, each electromagnet 2, 3, 4,
A control device (not shown) controls the currents of the electromagnets 2, 3, 4, and 5 so as to detect the movement of the electromagnets 5 and maintain the floating state with a constant gap. These electromagnets 2, 3, 4, and 5 are attached to the bogie frame 10, and are adapted to receive the load of the vehicle body 1 by air springs 17, 18. Here, solid tires 11, 1 are installed at the front and rear ends of the truck.
2 is attached, and when the levitation electromagnets 2 and 3 are demagnetized, the solid tire running treads 13 and 14 are mounted so that the load of the vehicle body 1 can be supported. A single side linear induction motor primary conductor (hereinafter referred to as
A single-side linear induction motor secondary conductor (referred to as SLIM primary) 15 is installed on a beam 19 that connects the rails.
(referred to as SLIM secondary) 16, the vehicle runs,
It is designed to provide the thrust necessary for deceleration.
Here, the beams 19 connecting the left and right rails are provided with relatively short pitches and are fixed on the girders 20. Furthermore, the girder 20 is supported via supports 21 provided on piers 22 provided at regular intervals.

Next, with reference to FIG. 2, problems when constructing a scissor crossing using a conventional flexible track type branching device will be explained. 23a and 23b indicate one double track track, and 24a and 24b indicate the other double track track. During this time 25a, 25b, 25c, 25d
Four normally conductive magnetically levitated vehicle branching devices are provided, and the structure of this branching device is the fully flexible type or joint flexible type branching device in which a single track is deformed to form a branch. shall be used. In this case, as shown in the figure, both tracks 23a and 23b must be able to connect to either of the mating tracks 24a and 24b.

However, this branching device
Since the dimensions are determined so that it can be connected to the track 23b or to the track 24b, the track 23a can be connected to the track 23a.
When trying to cross over to the track 24b via the tracks 25a and 25d, the dimensions A, which are determined by the center gap B of the double-track track, the total length L of the branching device, and the radius of curvature R of the branching device, are insufficient, and this sheath It is impossible to construct crossings. In the case of a normal monorail, long finger plates, etc. are used to forcefully cross the road with rubber tires, but in a normal conductive magnetic levitation vehicle, as explained in Figure 1, the track and the levitation or guide electromagnet 2, 3,4,5
Since the vehicle travels while measuring the gap with a gap sensor, if the track is cut in the middle, the gap between the track and the levitation or guide electromagnets 2, 3, 4, and 5 cannot be measured, making levitation control impossible. Therefore, such scissor crossing becomes impossible to construct.

This invention was made in view of the above circumstances, and its purpose is to prevent the tip of the branching device from crossing over to the diagonal track on the opposite side in scissor crossing for a normal conductive magnetically levitated vehicle. It is an object of the present invention to provide a scissor crossing device for a normally conductive magnetically levitated vehicle having a structure in which no gap is created between them.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 7. 3 and 4 are plan views showing, for example, the tip structure of the normal conductive magnetically levitated vehicle branching device 25d shown in FIG. 2 as the scissor crossing of the present invention. FIG. 3 shows the branching device 25d when it is connected to the branching device 25b, showing the branching device 25d in a contracted state, that is, the parallel double linear state, and FIG. 4 shows the branching device 25d connected to the branching device 25a. Therefore, it shows a state in which it is extended by dimension A, that is, a cross-shaped state. That is, the floating rails 6a, 7a, the guide rails 8a, 9a, the solid tire running surfaces 13a, 14a, and the secondary SLIM 16a are connected by a beam 19a and fixed on the girder 20 in FIG. The part on the right side of the figure constitutes a flexible structure as a branching device. On the other hand, the levitation rails 6b, 7b, the guide rails 8
b, 9b, solid tire running surface 13b, 14b
The secondary SLIM 16b is coupled onto the beam 19b and is slidable on the girder 20 to be displaced in the longitudinal direction of the rail. Insertion rails 26a, 26b are provided here, which function as described below. To explain the function of the insertion rails 26a, 26b, when the branching devices 25b and 24d are connected, the branching device can be short, so the insertion rails 26a, 26b
6b moves inward and levitation rails 6a, 6b,
7a, 7b, guide rails 8a, 8b, 9a, 9
b, solid tire running surfaces 13a, 13b, 14
a, 14b are partially connected across insertion rails 26a, 26b to form a short branching device. Also, when the branching devices 25a and 25d are connected, the length is short by the dimension A, but at this time the floating rail 6
b, 7b, guide rails 8b, 9b, solid tire running surfaces 13b, 14b, and secondary SLIM 16b move in the longitudinal direction of the rails together with the beam 19b. This amount of movement allows the device of the present invention to
If it is attached to both, the A/2 dimension will suffice, but in order to simplify the mechanism, it is considered advantageous to attach it only to the branching device 25d and move it by the required A dimension.
At this time, a gap is created between the fixed side rail and the movable side rail by the A dimension, but the insertion rails 26a and 26b have a total length (depth dimension) of 2A dimension, and the protruding portion is half the A dimension. Since the floating rails 6a, 6b, 7a, 7b,
Guide rails 8a, 8b, 9a, 9b and solid tire running surfaces 13a, 13b, 14a, 14b are constructed continuously. However, SLIM 2nd order 16a, 16
b creates a gap by dimension A, but SLIM secondary 16
Due to the characteristics of a and 16b themselves, they can pass through gaps of this size without any problem, but if you do not want this gap, install a secondary SLIM that is folded downward so that it becomes horizontal and fills the gap as shown in Figure 4. It should be configured as follows.

Next, as shown in FIG.
The configuration of the moving mechanism consisting of the SLIM secondary 16b, and the beam 19b will be explained. That is, at the tip of the girder 20a, the end of the girder upper plate 20b is projected like a flange 28, so that it fits into the bracket 27 provided under the beam 19b, and the bracket 2
Slit 20 provided in the girder upper plate 20b from the center of 7.
A piston cylinder 30 is connected to 29 after being inserted through bs. And girder 20a
is supported by a truck 31 having wheels 32 that are movable along rails 33. Therefore, the piston cylinder 30 is fixed to a fixed part (not shown).
The guide rails 8b, 9b and the floating rails 6b, 1 mounted on the trolley 31 are
3b, the beam 19, and the SLI secondary 16b as a whole move freely in the longitudinal direction of the rail (in the direction of the plane of the drawing). This girder 20a is connected to the rail 3 by means of a truck 31 and wheels 32.
It is now possible to move on 3 and perform branching operations.

Next, the insertion rail drive mechanism for driving the insertion rails 26a, 26b will be explained. As shown in FIG. 6, this includes insertion rails 26a, 26b,
It includes a widening/width widening mechanism for widening/shrinking this, and a piston cylinder 39. The widening/width reducing mechanism connects links 34a, 34b, 34c, and 34d,
The other end is connected to levers 35a and 35b that are rotatable around fixed rotation center pins 36a and 36b,
Furthermore, the levers 35a and 35b are connected by the link 37, and at the same time the piston rod 3 of the piston cylinder 39 is connected.
8, and the other end of the piston cylinder 39 is further fixed to a part of the raceway with a bracket 40. At the same time as this, guides 41a, 41b and support surfaces 42a, 42b, which will be described later, are attached to the insertion rails 26a, 26b. With this configuration, parallelogram links are formed on the left and right by the actions of the links 34a, 34b, 34c, 34d, levers 35a, 35b, and link 37, and the insertion rails 26a, 26
b shows the insertion rails 26a, 2 in the form of parallel movement.
6b The mutual width can be expanded or contracted.

How the insertion rail 26b having such a configuration is actually guided will be explained with reference to FIG. 7. That is, the guide 41b having a guide groove structure provided on the insertion rail 26b fits into the flange 7c provided on the floating rail 7a and the flange 14c provided on the solid tire running surface 14a, and furthermore, the guide 41b having a guide groove structure provided on the insertion rail 26b fits into the flange 7c provided on the floating rail 7a and the flange 14c provided on the solid tire running surface 14a. The support surface 42b provided in
By sliding on the back surface of the floating rail 7b, the insertion rail 26b can be held securely.

Note that the insertion rail structure used in the present invention is not limited to the above-described embodiments, and may be any structure as long as it can fill the rail gap according to the rail gap. In addition, various modifications can be made without changing the gist of the invention.

According to the invention described above, even if there is a slight gap between the rails, the gap is filled by the inserted rail, so it is necessary for the track configuration to be used for normally conducting magnetically levitated vehicles that have problems passing due to the nature of using gap sensors. It will now be possible to create the indispensable scissor crossing, and it will be possible to establish extremely advantageous conditions for the realization of low-pollution railways.
