Abstract

PURPOSE:To protect an on-vehicle electromagnet from contacting with a ground coil when a vehicle passes through a branch section by bending the movable switch section of a guideboard smoothly with constant curvature and performing switching operation. CONSTITUTION:A flexible board type point switching section 4 is arranged between guideboards 1, 2, 3 supporting a ground coil, where one end of the switching section 4 is secured continuously to the end section of the guideboard 1 and the other end thereof is made movable to the right and left. No ground coil is arranged at the switching section 4. A vehicle moves with the guide tire thereof contacting with the guideboards 1-3. When the guideboard 2 side of a switching board 5 is moved to the side of the guideboard 2, the switching section 4 comprising a flexible board is bent into a circle having radius R and coupled smoothly with the guideboard 1. By such arrangement, on-vehicle electromagnet does not contact with the ground coil when the vehicle moves through the switching section.

Description

[Detailed Description of the Invention] [Industrial Application Field] As shown in FIG. The vehicle is moved by the repulsion or attraction force, and the vehicle load is handled by support tires 14 provided on both sides of the truck.
This invention relates to a turnout (switch) for a type of linear motor transport device supported by a linear motor.

[Conventional technology]

In the above-mentioned transportation device, it is necessary to run the vehicle while maintaining an extremely small constant distance equal to the distance between the on-vehicle magnet 12 and the ground fill 13, for example, 10 mm. When three wheels are placed on a rail as in the past and the vehicle is run using the rail as a guide, the vehicle maintains a constant position with respect to the center line of the track due to the clearance between the seven lunges of the wheels and the rail. Therefore, with the above-mentioned ground-to-ground linear motor, it is not possible to run the vehicle while maintaining a constant distance between the on-board magnet 12 and the ground coil 13. Therefore, if the supporting plate of the ground fill 13 is used as the guide plate 15, and the truck 11 is guided by guide tires 16 suspended from the truck 11 on both sides of the guide plate 15, this problem will be eliminated. By the way, if the guide plate 15 is in the shape of a broken line when viewed from above at the branch point of the vehicle path,
There is a portion where the on-vehicle magnet 12 contacts the ground fill 13 provided at the end of the fixed guide plate 15.

[Problem to be solved by the invention]

In the present invention, the movable point portion of the guide plate 15 can be moved smoothly as a whole. By curving with the same curvature so that connections can be changed, it is possible to prevent the on-board magnet 12 from coming into contact with the ground fill 13 provided at the end of the fixed guide plate 15 when the vehicle passes through a branch. The present invention is intended to provide a turnout as described above.

[Means to solve problems]

Means for solving the above-mentioned problems according to the present invention is that a part of a band-shaped guide plate fixed along the vehicle path in the center of the vehicle path with the width direction perpendicular to the ground is flexible. formed of a material, one end of which is connected to another fixed part;
a point section whose other end is movable in the horizontal direction and is provided separately from the other fixed section; a fixed guide plate connected to the one end; and a point branched at an angle with respect to the guide plate. The point is curved into a circular arc that is in contact with the fixed guide plate, and the point is curved around a fulcrum near the one end on a linear extension from the fixed guide plate that connects the point to the one end. the other end of the part,
A flexible turnout for central guidance, comprising a horizontally movable switch device disposed below the transfer section.

The point is made of a flexible non-magnetic material such as fiber-reinforced plastic.

[Effect]

When the main line is a straight line and the main line is branched at an angle θ, the principle thereof will be explained with reference to FIGS. 1 and 2 as follows.

An arc connecting C and d where the straight section ad separated by the point 4 and the curve mac, which is an arc that touches the main line guide plate 1 and the branch side guide plate 3 at the time of branching, are equal,

One end side is connected to a fixed main line guide plate 1, and the other end is held by a pin 6 on a turning plate 5. If a flexible point part 4 is used in this state, it will become a straight line ad on the main line side,
On the branch side, the point portion 4 can be curved into a circular arc that touches the guide plate 1 having a length equal to the straight line ad.

In the figure, the length of the perpendicular line is determined so that the support tire 14 does not come into contact with the guide plate 3 on the branch side when passing the main line.

The fulcrum p can be found as follows.

In Fig. 1, a straight line connects the guide plate 1.2 from the end point C of the guide plate 3, which branches at an angle θ, with respect to the linear guide plate 1 and the linear guide plate 2 extending on the same straight line. If the length of the perpendicular line dropped above is 0.9 m, and the radius of the circle that touches guide plate 1 is 25 m, then Rcoaθ is R-D DxR-RcosθxR (1-aosθ) casθ-1

The guide plate 3 can be curved into a circular arc touching the guide plate 3.

This curving can also be performed symmetrically with respect to a straight line. By curving in this way, when the point section is moved, the distance between the on-board magnet 12 and the point section 4 is kept constant, and the on-board magnet 12 can be prevented from coming into contact with the ground fill 13. It can be prevented.
