Abstract

PURPOSE:To carry out necessary maintenance promptly by laying rails of the length at which a vehicle is easily removed from a rail, on a running path main body frame, in order, in line, by a bolt, and by forming the rails into one body, and by enabling removal of the rail at any one point. CONSTITUTION:Two rails 2, 2 running in parallel to one another, are provided and supported on and with a running path main body The cross section of the rail 2 is an L-shape, and its length is determined so that the rail can be easily laid on the running path main body frame 1 by a bolt 3, while it can be removed, and that a vehicle is removed. The rails are added until they are formed into one line, while a vertical piece 21 is put on the inner surface of the running path main body frame 1, and a mounting bolt 4 is inserted between the frame and the rail, and is fastened. The rail of a point at which a vehicle incapable of running stops, can be removed from the main body frame, and replacement and maintenance and the like of batteries can be carried out promptly and easily.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail device in which a vehicle can be easily removed at an arbitrary position on the rail in a magnetic levitation transport device.

[0002]

2. Description of the Related Art An apparatus for magnetically levitating a vehicle (transportation vehicle) used in a system for transporting various articles along a transportation route to drive the vehicle is disclosed, for example, in JP-A-60-17.
Nos. 0401 and 61-102105 are disclosed.

A conventional magnetic levitation carrier is equipped with a power source such as a storage battery, a permanent magnet and an electromagnet for magnetic levitation, and a controller for controlling an exciting current flowing through the electromagnet on the vehicle side. The vehicle is floated by magnetism so as to have a required gap, and the gap is detected by a gap sensor so that the vehicle always travels while maintaining an appropriate gap. However, if the storage battery installed in the vehicle is exhausted, you can replace the battery,
In the case of maintenance, it is necessary to transfer the vehicle from the rail to a removable station or to the end of the rail using human power or other power other than the vehicle.

It is an object of the present invention to easily remove the vehicle from the rail and perform maintenance or the like at a position where the vehicle cannot run by itself due to exhaustion or failure of the battery.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and the vehicle is run along the rails of the traveling path by being excited by an electromagnet mounted on the vehicle to levitate. In the magnetic levitation transport device, the rails of a length that allows the vehicle to be easily removed from the rails are attached to the runway body frame in a row one by one with bolts in sequence, and the rails can be removed at any position That is the summary.

[0006]

[Operation] A fixed-length rail is attached to the main frame of the roadway with bolts to form a single rail. For this reason, when the vehicle runs out and the battery becomes inoperable due to a malfunction when the vehicle is running, the rails at the stopped position of the vehicle can be easily removed from the body frame by removing the bolts, and battery replacement maintenance is possible. It can be done quickly and easily. Also, it is easy to attach the vehicle to the rail.

The present invention will be described below with reference to the illustrated embodiments. In the figure, reference numeral 1 is a main frame of a runway in a system for transporting articles between a plurality of points in a building, which is composed of a non-excitable magnetic material such as aluminum or aluminum alloy Two parallel rails 2 and 2 are disposed on and supported by 1.
This rail 2 is made of iron or other magnetizable material and has an L-shaped cross section, and other shapes such that at least the inner end surface and the lower bottom surface are flat. The mounting bolts 3 project and support them so as to face each other.

This rail 2 has an L-shaped cross section, and its length is appropriately determined so that it can be easily attached to and detached from the runway body frame 1 with bolts 3 and the vehicle can be detached. So, as an example, 2m-3
It can be about m, and the rails 21 of this rail 2 are aligned along the inner surface of the main body 1 of the roadway as shown in the drawing, and the mounting bolts are installed between the frame and the rail. Screw 4 through. In this case, if the protrusion is not projected on the inner surface of the rail, a screw hole is formed in the rail hanging piece 21 and a bolt 4 inserted from the outside of the main body frame 1 is screwed into the screw hole of the rail. Can be fixed. Further, the rails 2 and 2 projecting from the inner surfaces of the traveling path main body frame 1 facing each other are parallel to each other at equal height positions.

A vehicle (transportation vehicle) 3 traveling along the rail 2 of this traveling path has a pallet or cassette case pedestal 3 having a required size and shape on a vehicle body 31.
2, the reaction plate 33 of the linear motor is arranged on the lower surface, and when the vehicle 3 travels, when the vehicle 3 passes above the driving linear motor 4 arranged at a required interval on the side of the traveling path main body frame 1. , A required thrust is applied to the vehicle, and electromagnets 34 for levitation are installed at both front and rear end positions of the vehicle main body 3.
The magnetomotive force surface of No. 4 is made to face the lower bottom surface of the rail 2, and the vehicle is also provided with a guiding electromagnet 35.

A plurality of levitation electromagnets 34 are arranged so that the vehicle 3 floats substantially horizontally, for example, one each on the left, right, front and back, as shown in the drawing, and the gap between the lower bottom surface of the rail 2 and the magnetomotive force surface of the electromagnet 34. It is electrically connected to the control device and power supply (battery) mounted on the vehicle so that the set value can be maintained at The exciting current is controlled to adjust its magnetomotive force so that a predetermined gap is always maintained.

Further, the guide rollers 35 for guiding are attached to each rail 2
A plurality of rollers are provided so as to come into contact with the inner surface of the rail or open a required gap, and are guided by the guide rollers 35, 35 ... . Further, when the magnetic levitation force due to the electromagnet disappears in the vehicle body 31, support rollers 36, 36, ... For supporting the vehicle 3 on the rail 2 are provided at both front and rear positions of the vehicle.

[0012]

According to the present invention, the rail on which the magnetic levitation vehicle travels is set to a predetermined length, and this rail is fixed to the frame of the main body of the roadway by bolts so that rails of fixed size can be successively added. Because it is a rail shape,
If the battery needs to be replaced due to exhaustion of the battery or a failure occurs, the rail at that position can be removed from the main frame at the position where the vehicle is stopped, so that the vehicle can be easily removed from the rail for quick maintenance. It has the advantage that
