DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail device for running a guide track vehicle along a track, and a guide rail connecting device for connecting the guide rails of the device in an axially continuous manner.

[0002]

2. Description of the Related Art Referring to FIG. 4 showing a track guide portion of a conventional guide track vehicle, a vehicle body 31 on which a passenger is loaded is provided with an air spring 49 capable of controlling the internal air pressure according to the load amount. Axle body 3 that forms part of the carriage 30
2 mounted on.

[0003] At both ends of an axle 33 passing through an axle body 32, wheels 34a and 34b made of ordinary tires are rotatably mounted.
While carrying the total weight of the vehicle 1 and the carriage 30, the vehicle 1 travels on a track 35 made of concrete to a specified width.

A steering device 37 is rotatably mounted on the front surface of the carriage 30 via pins 39a and 39b via a rotating arm 36. Further, guide wheels 38a and 38b are rotatably provided at both ends of the steering device 37.

A guide rail device 40 is disposed in parallel along the track 35 with a pair of tracks 35 interposed therebetween and a steering device 37 interposed therebetween. The guide rail device 40 is formed by connecting a plurality of guide rails 40a fixed to posts 41a or 41b erected at appropriate intervals by a guide rail connecting device 50. A power supply line 42 for introducing drive power to the guideway vehicle is provided on one post 41b, and power is introduced from the power supply line 42 to the guideway vehicle via a current collector 43.

[0006] Each guide rail 40a is formed of H-shaped steel. The outer surface of the outer flange 40ao of the rail 40a is attached to the post 41a or 41b, and the outer surface of the inner flange 40ai near the track 35 is used as a guide surface. These many guide rails 40 a are connected to each other in the axial direction, and are installed over the entire track 35.

The operation of the steering device 37 will be described. Normally, when the vehicle body 31 is traveling in the center with respect to the track 35 without shifting, an appropriate gap is secured between the guide wheels 38a, 38b and the inner flange 40ai of the guide rail 40a. Have been. However, when the guide track vehicle is approaching a curve or traveling in one direction due to other reasons, for example, leaning rightward in FIG. 4B, the right guide wheel 38b is moved to the right guide rail device 40.
Is in contact with the inner flange 40ai of the guide rail 40a provided and receives a pressing force from the guide rail 40a. Due to this pressing force, the steering device 37 is displaced to the left, and at the same time, the connecting plate 44 connecting the bogie 30 and the steering device 37 via the pin 48 is also displaced to the left.

For this reason, as the fulcrum of the tie rod 45 rotatably supported by the pin 44a on the connecting plate 44 moves to the left, the lever 4 interlocks with the rod 45.
By operating 6a to the left, the direction of the right wheel 34b is changed to the left. At the same time, through the other lever 46b and the other tie rod 47 interlocked with it, the left lever 46
By displacing c in the right direction, the direction of the left wheel 34a is changed in the same direction as the right wheel 34b by the same angle.

When the vehicle body 31 travels to the left, the steering operation is reversed from the guide rail 40a provided on the left guide rail device 40, contrary to the above steering operation.
Via 8a, the steering device 37 is displaced rightward, and the direction of the wheels 34a, 34b is changed rightward.

That is, as described above, the steering device 37 is displaced by the action force from the guide rail device 40, and the steering is performed by changing the angles of the wheels 34a and 34b in proportion to the amount of displacement to the left and right.

As described above, the guide rail device 40
Plays an important role in stably driving the guided track vehicle on the prescribed track 35. The guide track vehicle keeps the guide wheels 38a, 38b in contact with and separates from the inner flange 40ai of the guide rail 40a of the guide rail device 40 as the vehicle travels, and particularly in the case of a sharp curve or the like, the guide wheels 38a, 38b. Is the inner flange 4 of the guide rail 40a.
I am traveling while repeatedly touching the 0ai.

Therefore, in order to improve the riding comfort by eliminating vibrations and noises and to suppress the wear of the mechanical components such as the guide wheels 38a and 38b, the surface of the inner flange 40ai of the guide rail 40a must be smooth. It is necessary to maintain a vertical surface without deformation. In particular, guide rail 4
It is important to eliminate a step due to a displacement in the width direction between the inner flanges 40ai at the connection portions of the 0a and a difference in the inclination angle of the mounting of the guide rail 40a.

Usually, a guide rail 40a having a length of several meters to about 10 m or more is used. When the track 35 is relatively straight, a long guide rail 40a is used.
A short guide rail 40a is used in a curved portion or the like.

Each of the guide rails 4 adjacent in the axial direction
0a are connected to each other using a connecting device 50 shown in FIGS. The conventional guide rail connecting device 50 shown in FIGS. 5 to 8 includes connecting fittings 51a and 51b, a sliding fitting 52, a liner 53, a connecting bolt 54, and a nut 55.

The connecting fittings 51a and 51b are U-shaped in cross section and have machine-finished surfaces on the bottom plate and the inner side plate that directly contact the web 40au of the guide rail 40a made of H-shaped steel. Seats 56a, 56 having
b is provided, and a hole 57 (see FIG. 9) provided on the web 40au and through which the connecting bolt 54 passes is connected to the connecting fitting 51.
guide rails 40 so that the positions of a and 51b can be adjusted.
It is a long hole long in the width direction of a.

As shown in FIGS. 7A and 7B, the slide fitting 52 is formed in an L shape, and its rising plate portion is machined with an appropriate taper so as to become thinner toward the tip. ing.

As shown in FIGS. 8A and 8B, the liner 53 is a plate having a length of approximately half the length of the slide bracket 52, and has a thickness of 0.5 mm to about 10 mm. Many are prepared for each. The connecting bolt 54 is provided with a lock nut for preventing loosening due to vibration or the like.

When the guide rails 40a, 40a adjacent to each other in the axial direction are to be joined together as shown in FIG. 9, the guide rail 40a (for example, as shown in FIG. A step M is formed between a vertical inner flange 40ai contacting the guide wheels 38a and 38b of the left guide rail 40a) and an inner flange 40ai of the guide rail 40a to be connected (for example, the right guide rail 40a in FIG. 9). May occur. Further, there may be a dimensional difference due to manufacturing variations in the inner dimensions H and H 'between the inner and outer flanges 40ao and 40ai of the guide rail 40a adjacent in the axial direction.

In order to connect and connect the guide rails 40a adjacent in the axial direction under such conditions, a guide rail having a large inner dimension as shown in FIGS. 5 and 6, for example, a connection at the right position in FIG. A liner 53 combined with an appropriate thickness is inserted into the guide rail 40a side, and the connecting metal fittings 51a and 51b are tightened with a connecting bolt 54 and a nut 55 via a sliding metal fitting 52. As a result, a force (horizontal force) for spreading is applied, and the inner surface of the flange 40ai of the guide rail 40a to be connected is connected to the connection fitting 5.
By contacting the seats 56b of 1a and 51b closely, it is possible to eliminate a step due to a displacement in the width direction between the flanges 40ai to which the guide wheels 38a or 38b can contact.

At this time, in order to fix the right guide rail 40a to be connected to the left guide rail 40a which is a reference in FIG.
b is a guide rail 4 made of H-section steel.
It is necessary to clamp and fasten the web 40au of 0a.

However, if the thickness of the liner 53 is too large, the connecting fitting 51a stops in the middle of the tapered portion of the slide fitting 52, and the seat 56a of the bottom plate cannot be in close contact with the web 40au. If the thickness of the combination 53 is too thin, a gap remains between the seat 56b of the connection fittings 51a, 51b and the inner surface of the inner flange 40ai of the guide rail 40a, and the flange 40ai of the adjacent guide rail 40a.
The step between them will not be eliminated.

Therefore, in the actual connection operation, an appropriate thickness of the liner 53 is selected, the connection fittings 51a and 51b, the slide fitting 52 and the connection bolt 54 are set, the nut 55 is tightened, and the connection fittings 51a and 51b are connected. The crimping state of the bottom plate portion 56a and the side plate portion 56b with the guide rail 40a and the step between the inner flanges 40ai are checked. Then, the nut 55 is loosened, the thickness of the liner 53 is adjusted, and the nut 55 is re-formed. , And the work of checking the pressure-bonded state of the seats 56a and 56b to the guide rail 40a and the step between the flanges 40ai is repeated to make corrections.

Also, as shown in FIG. 10A, even when the right guide rail 40a to be connected to the reference left guide rail 40a is inclined, the same as the above-described step M correction work. , Can be modified by the coupling device 50. That is, as shown in FIG. 10 (B), a liner 53 having an appropriate thickness is selected, and the seat 56 of each of the connecting fittings 51a and 51b is selected.
The connecting bolt 54 and the nut 55 are fastened and corrected so that the webs 40au and 56b of the guide rail 40a made of H-shaped steel are in close contact with the inner surface of the inner flange 40ai. As described above, the working method is as described above, while adjusting the thickness of the liner 53, tightening or loosening the nut 55 while pressing the seats 56a, 56b on the guide rail 40a, and the guide wheels 38a or 38b. Is performed in a repetitive operation of confirming a step on the guide surface (outer surface) of the inner flange 40ai with which the contact can be made.

In addition, in the connection operation, the slide fitting 52 is connected to the lower connection fitting 51b similarly to the upper connection fitting 51b.
The reason why the liner 53 cannot be adopted is that the work is difficult and impractical, for example, the liner 53 is dropped even if the liner 53 is set.

Therefore, the operation of connecting the guide rails 40a requires skill and requires a great deal of time and labor.
