JPS5929722B2 - Crossover point device for guided track vehicles - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the arrangement of guide rails in a point device provided on the track of a guide rail vehicle to form a crossing crossover.

Guided track vehicle means, for example, as shown in FIG.
This is a vehicle that is provided with guide wheels separately from the vehicle, and runs with the guide wheels running along guide rails 2L and 2R laid on both sides of the running path 1 to determine the direction.

As such a switching device for switching the direction of travel of a vehicle, one of the type shown in the figure has been proposed.

In other words, since there must be no obstacles on the running path 1, there is a method in which the guide rail of the point device 3 is bent and replaced over a certain section along with the running path as shown in Figure 2a, or As shown in the figure, there is a method in which guide rails 11, which are necessary for the vehicle's course, are made to protrude above the road surface, while guide rails 12, which obstruct the course, are sunk below the road surface, allowing the vehicle to pass. I've been exposed to it.

However, when considering the case of configuring a crossing wire using these methods, the method shown in FIG.
is required to be able to move by a distance s in a direction orthogonal to the trajectory.

As a result, a free space in the area 5, 5' indicated by diagonal lines in the figure is required, and a large amount of power is required to move the entire large-scale track including the running path, and a large base to support the moving body. , it is uneconomical in terms of construction and operation.

Moreover, since the moving distance S is large and the weight is large, it takes a long time to switch from left-handed to right-handed, for example, resulting in a reduction in operating efficiency.

On the other hand, the method shown in Fig. 3a is detailed in Japanese Utility Model Publication No. 55-55281, but if this method is used to form a crossing wire, the result will be as shown in Fig. 3b, and the switch device 10 will be as shown in Fig. 3a. The switch device 10' is almost the same as the switch device shown in the figure, although there is a difference in linearity. However, in this method, two single-open switch devices are installed between the double tracks, so not only does the double track spacing A become considerably larger than in the area without crossover wires, but in reality, six single-open switch devices are installed between the double tracks. A switching device is required, which is uneconomical in terms of production and operating costs.

Furthermore, since the length L of the crossing section becomes longer, the time taken for the train to pass becomes longer, which reduces the operating efficiency of the train accordingly.

As described above, the conventional cross connecting wire configuration has many drawbacks.

The present invention was made in order to solve these drawbacks of the conventional method, and it simplifies the mechanism by integrating the entire cross connecting wire switch device into one switch device, thereby reducing manufacturing and operating costs. The purpose of this invention is to provide a highly reliable cross-over point device.

Furthermore, the present invention can significantly reduce the installation space compared to conventional methods, increasing the degree of freedom in utilization, and shortening the length of the crossing section, thereby shortening the passing time of trains. It is an object of the present invention to provide a cross-crossing switch device that can enhance the operational effectiveness of a train group.
Next, an example will be described.

Fig. 4 shows the structure of the guide rail of the crossing point device according to the present invention, Fig. 4a shows the normal position, that is, the up and down lines are separated, Fig. 4b shows the left-handed state,
That is, a state in which the connecting wire is formed on the left side, and FIG. 4c shows a right-handed reversed state, that is, a state in which the connecting wire is formed on the right side.

This point device is broadly divided into a fixed guide rail, a vertically movable guide rail, a spiral guide rail, and an opening/closing guide rail. Two tracks with fixed guide rails 2, 2 provided on both sides are arranged close to each other.

Opening/closing guide rails 15 are provided at two locations on the fixed guide rails located on the outside of both rails.

The opening/closing guide rail 15 has one end attached in contact with the outer fixed guide rail, and the other end is a rail that can be opened and closed outward from the rail, and opens and closes in conjunction with the vertical movement of the straight and curved vertical movement guide rails described later.

On the other hand, a part of the inner fixed guide rails 2, 2 which are adjacent to each other between the two tracks is integrally configured as a linear vertical movement guide rail 11 which is movable up and down.

That is, one side 11U of the linear vertical movement guide rail 11 can be used as a movable guide rail for the up lane, and the other side 11D can be used as a movable guide rail for the down lane.

A vertical groove penetrating in the vertical direction is provided at both ends of the linear vertical motion guide rail 11, and the spiral guide rail 14 is positioned within this vertical groove.

This helical guide rail 14 has a hull shape that can rotate by a certain angle around a vertical axis 14a provided at the center, and its both sides serve as guide rails for the curved portions of both the up and down lines. A smooth curved surface connects the fixed guide rail 2 and an intermediate vertically movable guide rail to be described later.

The helical guide rail 14 maintains a state parallel to the track when in the normal orientation state, and in that case is housed in the groove of the ascending linear vertical motion guide rail 11, and when the linear vertical motion guide rail 11 descends, In other words, it can be rotated by a certain angle only to the left and right.

Furthermore, each track is provided with a curved vertical motion guide rail 12. The shape of this rail 12 is such that both free ends 12b are in contact with the outer fixed guide rail (see Figures 4b and 4c), and the planar shape is dogleg-shaped, with the central bent portion 12a located approximately at the center of the track. It is a long guide track.

Then, the inner surface from the free end 12b to the bent portion 12a is formed into a smooth curve along the line of the track, and this surface is used as a guide rail. This rail 12 and the opening/closing guide rail 1
5 operates alternatively, one of the rails connecting with the end of the outer fixed guide rail 2'.

Furthermore, two rails 13L and 13R of the intermediate vertical movement guide rail 13 are provided between the bent portion 12a of the curved vertical movement guide rail 12 of each up and down line and the straight vertical movement guide rail 11.

This rail also has a shape that follows the alignment of the track,
Its inner surface is used as a guide rail, and one end is a bent part 12a.
The other end is connected to that end when the linear vertical motion guide rail 11 descends and the spiral guide rail 14 spirals.

And two adjacent intermediate vertical movement guide rails 13
L and 13R do not rise at the same time, and only when the curved vertical motion guide rail 12 rises, only one of the intermediate vertical motion guide rails rises, and its end connects with the twisted spiral guide rail 14. become.

Next, the operation will be explained.

(B) Orientation (straight line side opening) (Fig. 4a) The linear vertical motion guide rail 11 rises, and both sides 11U, 11
D can be used as a guide rail.

The helical guide rail 14 is accommodated in the vertical groove of the linear vertical guide rail 11.

The opening/closing guide rail 15 is connected to the outer fixed guide rail.

Then, the other guide rails 12 and 13 are lowered so that their upper surfaces coincide with the track road surface and form part of the road surface.

Therefore, the straight side is open.

(b) Reversal (opening on curved side) (Figures 4b and 4c) The linear vertical movement guide rail 11 is lowered, and the opening/closing guide rail 15 is opened outward.

The curved vertical movement guide rails 12, 12 of both the up and down tracks are raised, and straight movement of both tracks is prevented.

Then, one set of opposing rails 13R or 13L among the four intermediate vertical movement guide rails 13 is raised, and the helical guide rail 14 is twisted so as to connect with the raised rail end. Therefore, which set of intermediate vertical motion guide rails 13
Depending on whether you want to raise it, you can choose whether to take the left side (Figure 4b) or the right side (Figure 4c).

Next, a driving device for driving the above-mentioned rail group will be explained.

In FIG. 5, the curved vertical motion guide rails 12, 12 of both the up and down tracks are connected by a common first shaft 11 via cranks 22, 22 in the same phase direction, respectively. Note that connection using cranks in the same phase direction means that they move up and down at the same time, and connection using cranks in different phase directions means that when one goes up, the other goes down.

A clamp 21 is provided on the first shaft 21 in a phase direction different from that of the crank 22. The linear vertical motion rail 11 is connected via a clamp 21, and is connected via another crank 25 to a link 12 that operates the opening/closing guide rails 15, 15.

On the other hand, the second shaft 13 has one end connected to the intermediate vertical motion guide rail 13 via the crank 23, and the other end connected to the intermediate vertical movement guide rail 13 via the crank 24.
will be established.

The crank 24 is configured so as to be able to apply only a horizontal force for spiraling to the spiraling guide rail 14 via the link 24.

When the link 14 is in the normal position, the intermediate vertical motion guide rail 13R,
Both 13L are in a downwardly yielding state, and 13R is configured to be raised in the right lateral position, and 13L is raised in the left lateral position. Two more links! 4 and 14 are connected by a link 15 to a drive device 26
Driven by. Therefore, when the drive device 26 is driven, the intermediate vertical motion guide rail 13 and the helical guide rail 1 which are integrally connected
4 are driven simultaneously to form a rail.

The two first shafts 11 are connected by a link 16 provided parallel to the track, and if a drive device 27 is connected to this, the linear vertical guide rail 11 can be lowered and the curved vertical guide rail 12 can be raised. , a series of operations such as an outward opening operation of the opening/closing guide rail 15, and the opposite operation can be performed simultaneously. On the other hand, as shown in FIG. 6, an example of a drive device for a conventional single-opening switch device shows that there are two cranks 21 that move the linear vertical motion guide rail 11 up and down, and two cranks 21 that move the curved vertical motion guide rail 12 up and down. There are two cranks 222,
Further, a crank 25 for opening and closing the opening/closing guide rail 15 is provided.
It is necessary to install each location individually. According to such a system, the single-opening switch device 1 is used to configure the crossing crossover wire.
Six zeros had to be used, and as mentioned above, the configurations of the guide rails and drive devices were numerous and complex.

The drive device of the present invention has a significantly reduced number of crank devices and is mechanically simpler than the prior art.

In the present invention, since the entire switch device is constituted by one device as described above, it is possible to simplify the mechanism and reduce manufacturing and operating costs.

Since the mechanism is simple, highly reliable operation can be provided.

Furthermore, since the installation space is small, the degree of freedom of use is expanded, and the operating time is shortened, which improves operating efficiency.
It has many advantages such as being able to choose the dimensions.
