It is a schematic sectional drawing of a connection part.
The transportation vehicle according to the reference example of the present invention is configured to travel while being guided along the traveling track 1 by rolling the guide wheels 3 constituting the guide device in contact with the guide rails 2. Therefore, as shown in FIG. 1 and FIG. 2, the guide device includes guide rails 2 installed on both the left and right sides along the traveling track 1 that is the route of the new traffic system, and front and rear body parts of a traffic vehicle (not shown).

  Such a guide rail 2 is composed of two types of main guide rails 21 and branch guide rails 22 which are installed in the traveling track 1 in a related manner. The main guide rail 21 is formed using, for example, a rigid H-shaped steel material, and is provided on both the left and right sides on the track surface of the traveling track 1. Further, the branch guide rail 22 is formed using, for example, a steel material having an L-shaped cross section having rigidity, and is installed at a branch point 1a that is located in the middle of the travel track 1 and leads to another travel track. The support member 23 is erected on the lower inner raceway surface of the main guide rail 21.

On the other hand, the guide wheels 3 of the guide device according to the reference example of the present invention are rotatably provided at the left and right end portions of the front and rear guide cross beams (not shown) extending in the vehicle width direction of the traffic vehicle, It is composed of a main guide wheel 31 and a branch guide wheel 32 which are arranged vertically via a wheel shaft 33 with the shaft center displaced. The main guide wheel 31 is positioned above the branch guide wheel 32 and is in contact with the side surface of the main guide rail 21. When the main guide wheel 31 comes into contact with the main guide rail 21, the main guide wheel 31 has an outer main wheel. A lateral load inward from the guide rail 21 is applied.
The branch guide wheel 32 is positioned below the main guide wheel 31 so as to be in contact with the side surface of the branch guide rail 22. A lateral load from the branch guide rail 22 toward the outside is applied. In this way, when the main guide wheel 31 or the branch guide wheel 32 receives a lateral load from the main guide rail 21 or the branch guide rail 22, the traffic vehicle can travel on the travel track 1 of the predetermined operation route.

A mounting hole 14 to be inserted and mounted is formed corresponding to the pin hole of the stay 12. Further, the buffer member 11 is formed in a cylindrical shape, and its outer diameter is set to a size that can be inserted into the pin hole of the stay 12 and the mounting hole 14 of the rolling rod 41, 42, and its inner diameter can be inserted into the pin 13. Is set to a large size.
Therefore, the support member 23 and the stay 12 of the branch guide rail 22 and the end portions of the rolling rods 41 and 42 are shock-absorbing by inserting the buffer member 11 and the pin 13 into the mounting hole 14 and the pin hole. They are connected to each other with their functions.

  In the transportation vehicle branching device according to the reference example of the present invention configured as described above, the support member 23 and the stay 12 of the branch guide rail 22 and the ends of the rolling rods 41 and 42 of the rolling machine 4 are connected to the buffer member 11.
