Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a monorail branch point structure.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a monorail car that travels on a monorail by being guided by guide wheels that roll on the upper and left and right side surfaces of the monorail.
[0003]
[Problems to be solved by the invention]
However, the branch point that changes the destination of the monorail car has a complicated structure in order to avoid interference with the guide wheel. Further, the monorail car refracts and the monorail car swings at the branch point. There is a problem that the ride speed is poor and the speed limit when passing through a branch point has to be lowered due to safety detection.
[0004]
[Means for Solving the Problems]
Therefore, in the present invention, the monorail car has a branching point structure for changing the destination of the monorail car , and the monorail car can be driven by engaging a pinion with a rack attached to the rail, and the end portions of the three rails are A pedestal is installed at the branch point of the concentrated monorail, a bearing is provided on the pedestal, a pivot extending vertically is inserted through the bearing, and the upper end of the pivot is curved in a substantially arc shape in plan view. The center of the point rail is fixed, and racks are attached to both the left and right sides of the point rail. Both ends of the point rail are opposed to the ends of the two rails of each of the rails. In addition, in a state where the point rail is rotated halfway around the pivot, both ends of the point rail can be opposed to the ends of two rails having a different combination from the above. It is intended to provide a monorail branch point structure characterized by the fact that it has been formed.
[0005]
Moreover, it has the following features.
[0007]
A rail connection portion for connecting the three rails to the pedestal is provided, and a lock mechanism is provided between the rail connection portion and the point rail.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention is as follows.
[0009]
A pedestal having a substantially rectangular frame shape in plan view is installed at a branch point of the monorail, a rail connecting portion is provided at the center of one short side of the pedestal, and the end of the first rail is fixed, and the short side facing the short side And rails at the corners of the long sides of the two sides, respectively, and the ends of the second and third rails are fixed to the rail connections, and a bearing is provided at the center of the base. A point rail that is pivotably inserted into the bearing portion in a vertically extending manner, a sliding disc is fixed to the upper end of the pivoting shaft, and the upper surface of the sliding disc is curved in a substantially arc shape in plan view. The both ends of the point rail are oppositely opposed to the end portions of the first rail and the second rail, and the point rail is rotated halfway around the pivot axis. , Both ends of the point rail are butted against the end of the first rail and the third rail And to be able to counter.
[0010]
In this way, a point rail that is curved in a substantially arc shape is used for the branch of the rail, so that the sudden refraction of the rail at the branch point is eliminated and the monorail car is less shaken, so the ride comfort is improved and the branch is made. Speed limitations at points can be relaxed.

[0014]
In the branch point structure, a pedestal 8 that is formed in a substantially rectangular frame shape in plan view is installed on the ground surface of the branch point P, and a first rail 1 is connected to the center of the short side of the upper surface of the pedestal 8. A rail connecting portion 11, a second rail connecting portion 12 for connecting the second rail 2 to the upper surfaces of the corner portions of the short side facing the short side and the long sides on both sides thereof, and the third rail 3 And a third rail connecting portion 13 for connecting the two, and a point rail RP is provided at the center portion of the pedestal 8 so as to be turnable in the left-right direction so that the travel route can be switched.
[0015]
As shown in FIGS. 2 to 4, each rail connecting portion 11, 12, 13 has a substantially rectangular mounting plate 14 stretched on the upper surface of the base 8, and a large-diameter square pipe on the upper surface of the mounting plate 14. 15 is attached in parallel to the rails 1, 2 and 3, and a mounting base 16 is formed on the upper surface of the outer side to attach the ends of the rails 1, 2, and 3. The rails are mounted on the upper surface of the inner side. Short rails 17 formed in substantially the same manner as 1, 2, 3 are laid so that the rails 1, 2, 3 and the short rails 17 are smoothly continuous. Serrations are formed on the upper surface and meshed with serrations formed on the lower surfaces of the end portions of the rails 1, 2, 3 to prevent the rails 1, 2, 3 from shifting in the longitudinal direction.
[0016]
As shown in FIGS. 2, 4 and 5, the point rail RP is provided with a bearing portion 20 at the center of the base 8, and a pivot shaft 21 extending in the vertical direction is inserted into the bearing portion 20 so as to be rotatable. The sliding disk 22 is fixed to the upper end of the pivot shaft 21 and the upper surface of the sliding disk 22 is connected to the upper surface of the sliding disk 22 via the square pipe 15. The center part of the point rail RP that is curved in a substantially arc shape is fixed, and both ends of the point rail RP are abutted against the inner ends of the first rail connecting part 11 and the second rail connecting part 12. And both ends of the point rail RP are connected to the first rail connection portion 11 and the inner end portion of the third rail connection portion 13 in a state where the point rail RP is rotated halfway around the pivot 21. The first and second rails 1 and 2 or the first and third rails 1 and 3 are contiguously opposed so that the first and third rails 1 and 3 are continuous. The rail 1 and the second rail 2 or the first rail 1 and the third rail 3 are made to be continuous with a smooth curve, and sliding plates 23 are respectively stretched on the lower surfaces of both ends of the point rail RP. The lower surface of the sliding plate 23 is in contact with the upper surface of the mounting plate 14 so as to support both ends of the point rail RP from below. The central portion of the point rail RP is supported from below by the contact between the upper surface of the base 8 and the lower surface of the sliding disk 22.
