DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch girder of a straddle-type monorail, and more particularly to a device for jointly displacing a traveling plate for receiving a guide stable wheel of a wheel at the same time as a branch point. .

[0002]

2. Description of the Related Art FIGS. 1 and 2 show a conventional structure. At the same time as the branch girder is turned, the link mechanism is pushed by the cylinder 5 installed below the branch girder, so that the guide stabilizer bending driving device 6 installed inside the branch girder operates. In this driving device, several cams 7 are provided on one branch girder, and the cam grooves are rotated by the force of a cylinder to thereby connect the guide plate and the stabilizer plate 8 to the right and left and up and down. Is a device that moves in the pivoting direction, curves the guide stable surface, and curves to a reliable curved line R.

[0003]

In the above prior art, no consideration has been given to assembly, maintenance and replacement of parts.

That is, in order to replace the cam mechanism 7 installed inside the branch girder and the cam follower 9 installed on the connecting rod 3a, the guide plate stabilizer 8 is removed and the components inside the branch are replaced. Was. In addition, it takes a considerable amount of time to assemble, and it is difficult to adjust and work inside the branch girder. Therefore, work efficiency is low and the number of parts is large.

[0005]

The bend angle between the branch girders is reduced, and the problems of the strength of the bogie and the right and left riding comfort are solved. ADVANTAGE OF THE INVENTION According to this invention, a guide stable surface is broken without power, and a bending angle becomes about 1/2, and it is possible to drive | run more smoothly than before. Moreover, assembly, maintenance and maintenance can be easily performed, and the efficiency of assembly work and the number of parts can be reduced to reduce costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows an articulated guide stable surface bending device of a straddle-type monorail turnout device. The branch girder has a box-shaped cross section, and the connection system is a T-shaped shaft with 10 pins. The guide stabilizing plate 8 at the middle part of the branch girder is a completely fixed type of a welding attachment structure to the girder body, and the end of the branch girder is a guide stabilizing plate 8a.
Separately, and make the bending angle θ of the branch girder about １ ／. The basic line shapes of the branching devices are θ, 3θ, 5θ, and 7θ, which are the mechanisms for forming the relaxation curve. The bend angle is a difference in the bend angle between the branch girders when the branch girder is turned. The smaller the branch plane curve R, the larger the bend angle. If the angle of bend is large or the plane curve R is small, the running speed of the monorail vehicle is affected. Therefore, the angle of bend is reduced to improve the operation of the monorail vehicle. The guide stabilizing surface folding device is provided with a detachable guide plate stabilizer 8a which is easy to assemble,
The mounting method is a pin connection, and one side is a fixing pin 1 and the other side is a mechanism 2 capable of performing an escape operation. For the fixing pin, a mounting seat is installed on the branch girder main body, a receiver is mounted, a pin is inserted inside the receiver, and a retaining seat is installed. The receiving inside incorporates a bush whose rotation mechanism is easy. On the movable side, the left and right guide stabilizers are connected by a connecting rod, and a penetrating elliptical hole is provided in the branch girder to enable firm relief operation. In order to eliminate the step between the guide stabilizing surfaces after the turning operation of the branch girder, the connecting rod is fixed at the center of the branch girder and follows the branch girder as a mechanism for supporting the movable side connecting rod. As in the case of the conventional finger plate, importance is placed on the riding comfort of a monorail vehicle, as in the conventional finger plate, in the gap between the guide stable surfaces. Detachable guide stabilization surface is connected with a connecting rod to maintain the girder width,
The connecting rod is of a turnbuckle type in consideration of the workability of assembly, and the connecting rod, the guide plate, and the stabilizer are provided with spherical bushings to allow for allowable rotational movement. This detachable guide stabilizer is no.
One digit and No. Between two digits, No. 2 digits and No. Between three digits,
No. 3 digits and No. Install between 4 digits.

[0007]

According to the present invention, the number of parts is reduced, maintenance and assembly are facilitated, the cost of the switch is reduced, and the reliability is improved.
