Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a branching device for controlling the course of tracked vehicles such as those in new transportation systems.

For example, the trajectory of this type of vehicle will be explained with reference to FIG. 4. The running wheels 2 supporting the weight of the vehicle 10 and traveling
There is one that consists of a receiving surface 3 and left and right guide walls 5 that are in contact with guide wheels 4 provided on both sides of the vehicle 1, respectively.

Conventionally, as a means for branching the running of the vehicle 1 at such a branch S of the track R, a means for moving the guide wall 5 of the branch in parallel in the branching direction, a floating type or a 180 There are those with a rotating guide wall, and those with a switch plate similar to a railway turnout.

However, since both have movable parts on the track H, it is necessary to install the drive device on the track R side, which poses a problem in terms of maintenance.

Therefore, as described in Japanese Unexamined Patent Publication No. 48-29174, in the part where the track R branches to the left and right, a rail that branches to the left and right in the same way as the track R is provided, and on the left and right sides of this rail, the vehicle can A technique has been devised in which a provided contactor is selectively brought into contact with the vehicle to selectively drive the vehicle on the left-hand track and the right-hand track.

However, in the technique described in the above publication, the contact and the guide wheel are integrated, and when switching the contact surface of the contact, the guide wheel moves away from the guide wall and comes into contact with the guide wall on the opposite side. During that time, there is nothing to restrict the left-right movement of the vehicle, and if the vehicle enters the branch while swaying left and right, the contactor will not come into contact with the desired side of the rail.
There is a problem that the running of the vehicle is not branched in a desired direction.

There is also the problem that the guide wheels move due to the reaction force from the rail against the contactor, causing the vehicle to sway.

This invention takes the above points into consideration, and makes contact with the branch rail with a wheel that operates separately from the guide wheel.
The purpose is to solve the above problems.

That is, the branching device of the present invention has a track consisting of a receiving surface for the running wheels that support the weight of the vehicle as described above, and left and right guide walls in which the front and rear guide wheels provided on both sides of the vehicle are laterally in contact with each other. In the part where the wheel branches left and right, a branch rail that branches left and right in the same way as the track is provided at the center between the two guide walls, and the center line is used as a boundary between the front and rear of the center between the two guide wheels on the underside of the vehicle. Auxiliary guide wheels movable left and right are provided so as to move independently of the guide wheels, and the front and rear auxiliary guide wheels are moved left and right to contact selected surfaces on the left and right sides of the branch rail. The vehicle is equipped with a drive device that causes the vehicle to move.

With this configuration, the auxiliary guide wheels are selectively moved left and right and come into contact with the left and right sides of the branching rail to determine the running direction of the vehicle, so a fixed guide wall is installed at the branching section of the track. Just by installing it, there are no moving parts at all.

Therefore, the structure of the branch part on the track side becomes extremely simple.

In addition, since the guide wheels and the auxiliary guide wheels are made to operate separately, that is, the vehicle's guiding action and branching action are made independent, so that branching is performed while the left and right movement of the vehicle is restricted by the guide wheels. be able to.

Therefore, the branching action is also smooth and reliable.

Furthermore, since a guide wheel and an auxiliary guide wheel are provided at the front and rear, and a total of four wheels are used for branching, the vehicle is reliably controlled and does not sway even during branching.

Hereinafter, embodiments will be described based on the accompanying drawings.

As shown in FIG. 4, the track R has left and right receiving surfaces for receiving the running wheels 2 on both sides of the vehicle 10, and left and right guide walls 5 with which the front and rear guide wheels 4 on both sides of the vehicle 1 laterally contact. As shown in FIGS. 1 and 2, it branches left and right into a main line side track R1 and a side line side track R2 at any arbitrary point.

In this branching part S, a branching rail 6 that branches left and right like the track R is provided at the center of the left and right guide walls 3, and this rail 6 runs from the tip 7 at the center of the entrance to the branching part S of the track R. , the width gradually becomes wider before the branch S, and the width gradually increases until the branch S
It branches into a main line side 8 and a side line side 9 before the branch, and after the branch S, it gradually becomes narrower and ends slightly inward.

A bogie A is rotatably attached to the front and rear of the vehicle 1, and traveling wheels 2 are attached to both sides of the central member 10 of the bogie A.
Guide wheels 4 are attached to both ends of both end members 11.

These wheels have rubber tires.

12 is an auxiliary guide wheel with rubber tires provided at the front and rear of the vehicle 10, and this wheel 12 is connected to a guide cover 14 at the tip of a guide arm 13.
It is installed at the bottom of the

The rear portion of each arm 13 is attached to the central member 10 by a shaft 15 so as to be rotatable back and forth.

A guide shaft 16 is provided at the center of the both end members 11 as shown in FIG.
A U-shaped guide cover 14 is placed over this shaft 16 to prevent the guide arm 13 from moving up and down.
A book reinforcement material 17 is provided.

Furthermore, stoppers 18 are provided at both ends of the guide shaft 16 to limit the range of left and right movement of the guide arm 13.

Reference numeral 19 denotes an actuating member attached to the lower side of the central member 10 so as to be able to move left and right.The inner ends of the guide arms 13 are connected to both sides of the actuating member with pins 20, etc., so that when the actuating member 19 moves, the guide arms 13 move left and right. The auxiliary guide wheel 12 is configured to rotate to the left and right with the rail 6 as a boundary.

Further, a drive device 21 such as an air or hydraulically operated cylinder is provided at the lower part of the central member 10, and a control circuit is provided to freely operate this drive device 21 by a branch switching signal.

The embodiment is configured as described above, and its operation will be explained next.

First, before entering the branch S, the auxiliary guide wheel 12 on the vehicle 1 side has moved to a position where it can contact either the left or right side of the rail 6.

That is, first, when the drive device 21 of the front and rear bogies A of the vehicle 1 receives a branching command and moves the actuating member 19 to a desired side, the guide arm 13 rotates via the pin 20, and the guide cover 14 is moved to the stopper 18. It rotates until it hits.

In this state, when the vehicle 1 approaches the branch S, if the front and rear auxiliary guide wheels 12 are on the main line side, the wheels 12 enter from the main line side of the tip 7 of the rail 6 as shown in FIG. Since the vehicle 1 runs in contact with the side surface of the main line side 8, the vehicle 1 is guided by the guide wheels 12 and runs toward the main line side rail R1.

Further, when the front and rear auxiliary guide wheels 12 are switched to the side track side as shown in FIG. 2, the wheels 12 move along the side track side 9 of the rail 6, so the vehicle 1 is not guided to the side track side rail R2. Ru.

During this branching action, the auxiliary guide wheel 12 moves independently of the guide wheel 4, and a guide wheel and an auxiliary guide wheel are provided at the front and rear, respectively, so that a total of four wheels are used to branch.
The wheels 4 are always in contact with the guide wall 5, so that the truck A does not sway from side to side and reliably runs on a desired trajectory.
