Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rail for running a trolley for transporting a load such as a hoist, and relates to a nine-power feed-built-in rail that has a built-in nine-way O power feed line for feeding power to the hoist or trolley.

As shown in Fig. 1, the rail 1 has a substantially cross-sectional shape at right angles to the length direction and has a longitudinal opening groove in the center of the lower wall, and the rail 1 carries loads along the inner surface of the lower wall on both sides of the opening groove. The hoisting machine 3t is used so that the trolley 2 is run and the hoist 3t is suspended from a part of the trolley that protrudes downward from the opening groove. When a cable power supply system is adopted for power supply to the Toro IJ 3 or the hoisting machine 3, the power supply cable 5 is configured to be supported by a large number of cable carriers 4 running on the same range 1.

In such a load transfer device, since a large number of cable carriers 4 run on the same rail 1, it is impossible to run the trolley 2 to the end of the rail 1, and the running of the trolley 2 is difficult considering the length of the rail 1. The disadvantage is that the distance is short. Furthermore, when the rail 1 is lengthened, the power supply cable 5 is correspondingly lengthened and the number of cable carriers 4 is also increased, so that a large traction force is applied to the power supply cable 5.

There was also a device along the length of the rail l. Furthermore, since only one power supply cable S can be wired from each end of the rail 1, two or more trolleys 2 can be connected to one rail 1.
I couldn't get it to run. - In order to eliminate the above-mentioned inconveniences, there is a trolley power supply method in which a power supply contact wire is installed parallel to the rail L, but it is necessary to install the power supply contact wire separately from the rail L. Because it is a loincloth wire, there is a high risk of electric shock and short circuit accidents, and it also has the disadvantage that it cannot be used in areas with a lot of dust.

Therefore, an object of the present invention is to effectively utilize the length of the rail of a load-transferring trolley, to reduce the risk of electrical shock and short-circuit accidents during facility work on power supply contact wires, and to reduce the risk of electrical shock and short-circuit accidents.
To provide a power feeding bundle internal rail which can be used at any place and can be lengthened as necessary to allow a large number of load carrying trolleys to run at the same time.

To achieve this objective, the present invention has a cross-sectional shape perpendicular to the length direction of the rail, which is approximately in the shape of an opening, and has an opening groove extending in the length direction at the center of the lower wall, and loads are applied along the inner surface of the lower wall on both sides of the opening groove. The transport trolley is made to run, and a plurality of power supply conductors whose left and right sides and top surfaces are coated with an insulating material are arranged in the upper part of the inner space of the rail at predetermined intervals in a direction perpendicular to the length direction of the rail. The insulating snout of each power supply conductor is fixed to the inner wall of the rail at predetermined intervals in the length direction via supporting members, and the power supply conductor and rail are integrated, eliminating the need for separate installation work. Insulating coating is placed above the internal space of the rail to reduce electric shocks, short circuits, and dust build-up, and the current collector of the load carrying trolley running on the rail or the separately prepared power supply trolley is placed inside the rail. Since it is possible to supply power to the load carrying trolley or hoisting machine by contacting the power supply conductor with the rail, the rail length can be set relatively long, and it can be effectively used for running the load carrying trolley. Accordingly, a large number of load conveying trolleys can be run simultaneously.

The following will explain the embodiments shown in the drawings. FIG. 2 is a cross-sectional view at right angles to the longitudinal direction of the rail showing a state in which seven power feeding trolleys are running on the rail, and FIG. 3 is a partially cutaway view.

The rail 1 has a substantially cross-sectional shape perpendicular to the length direction, and has an opening #1 layer in the length direction at the center of the lower wall.

It is supported as follows. Each insulator 1G-

JG on power supply trolley 15! When the brushes 22 to 25 come into contact with the power supply conductors 6 to 9 within the rail, power can be supplied to the load transport trolley 156 or the hoisting machine 3. 15, and if necessary, the rail length can be increased to allow a large number of load conveying trolleys 2 to travel. In addition, since each of the power supply conductors 6 to 9 is covered with insulators 10 to 13 on both left and right side surfaces and the top surface, the strength is reinforced and the spacing between the supporting members 14 can be increased. Furthermore, it is possible to prevent electrical short circuit accidents caused by deflection of the rail 1 and the power supply conductors 6 to 90 due to the load.

In the above embodiment, the brushes 22 to 25 are provided on the power feeding trolley 15, but the same power feeding can be achieved even if they are provided on the load conveying trolley 2. Control signal communication with an external control circuit or the like is also possible by similarly adding 9 control signal lines in which part of the 9 power supply conductors 6 to 9 are used as control signal lines.

As described above, according to the rail with a built-in power supply line of the present invention, the cross-sectional shape perpendicular to the length direction of the rail is approximately in the shape of an opening, and the opening groove in the length direction is provided at the center of the lower wall, and the inner surface of the lower wall on both sides of the opening groove. At the same time, a power supply conductor whose left and right sides and top surface are covered with an insulating material is placed at a predetermined interval in the direction perpendicular to the length direction of the rail in the upper part of the inner space of the rail. By arranging a plurality of power supply conductors and fixing the insulators of each power supply conductor to the inner wall of the rail at predetermined intervals in the length direction via supporting members, the power supply conductor and the rail are integrated, so they can be separated from each other. There is no need for installation work, and the power supply conductor is insulated and stored in the upper part of the internal space of the rail, reducing electric shocks, short circuits, and dust accumulation. By bringing the current collector of the power supply trolley into contact with the power supply conductor within the rail, it is possible to supply power to the load transport trolley 01J or the hoisting machine, so the rail length can be set long and the load transport trolley travels effectively. Furthermore, it is possible to run a large number of load conveying trolleys at the same time if necessary.
