Description

[Detailed description of the invention] This invention is designed for use on transportation rails that are difficult to inspect on a daily basis, such as tow truck running rails for model tests used in test water tanks, rails for crane hoists installed in high places, etc. The present invention relates to a device for removing foreign matter.

FIG. 1 shows a foreign matter removal device that has been conventionally used on the towing rail of a model ship in a test tank. That is, running rails 2 are arranged on both sides of the test water tank 1, and a towing truck 4 equipped with drive running wheels 3 runs on the rails, straddling the water tank 1.

The aquarium towing cart 4 travels at a predetermined speed and is used to pull or track a specimen (not shown) supported by the cart 4, and highly accurate speed control is performed.

In addition, in order to accurately measure the hydraulic force applied to the specimen, the vibration of the trolley 4 must be kept as small as possible.

Therefore, the rails 2 are different from ordinary railway rails in order to prevent speed fluctuations and vibrations of the bogie, and are made of highly precisely finished steel rails in order to maintain the levelness of the upper surface of the rails. Moreover, it is necessary to keep the upper surface of the rail clean at all times, maintain precision in controlling the speed of the carriage 4, and prevent vibrations such as vertical movement of the carriage 4.
However, inside the aquarium building, there is a high humidity environment due to the steam evaporating from the aquarium, making it difficult to prevent iron rust from forming on the steel rails. Such minute iron rust or the slightest metal foreign object on the upper surface of the rail can cause speed errors in the towing vehicle and vibrations during running. For this reason, wire brushes 5 are attached to the front and rear lower ends of the towing cart 4 shown in FIG. 1 to scrape off the iron rust on the upper surface of the rail.

This wire brush 5 is a disc made of steel wire planted in a disk, and is rotatably attached to the lower end of the towing cart around a vertical axis, so that the lower end of the wire brush 5 is in contact with the rail 2. There is.

Furthermore, since the wire brush 5 is mounted eccentrically with respect to the center of the rail 2, as the towing vehicle 4 travels, the wire brush 5 generates a frictional force with the rail 2 due to its own weight and rotates. It is designed to have the effect of scraping off iron rust and steel foreign matter on the rail 2.

However, the iron rust and steel foreign matter released from the rail 2 by the wire brush 5 cannot be completely removed from the rail by the wire brush 5 alone, and a considerable amount of foreign matter remains on the rail. .

Further, foreign matter attached to the wire brush 5 may fall onto the rail 2 again. Furthermore, the wire that is a component of the wire brush 5 may fall off and fall onto the rail 2 and remain there.
If the wheels 3 ride on these foreign objects remaining on the rails 2, it not only causes speed errors and vibrations, but also causes problems such as scratches on the surfaces of the rails 2 and wheels 3. Therefore, regular manual inspection and cleaning of the upper surface of the rail are essential, and there is a drawback in that a great deal of effort is required to protect and maintain the rail.

In order to solve the above-mentioned drawbacks of the conventional device, the present invention has been developed by attaching a magnet to the towing cart in close opposition to the rail, and further inserting a rotating belt between the magnet and the rail to scrape it off the rail with a brush. An object of the present invention is to provide a device for removing foreign matter on a rail, which automatically collects and removes iron rust (fine iron rust) and maintains the accuracy of the upper surface of the towing vehicle rail.

For this reason, the device for removing foreign objects on the rail of the present invention is
A wire brush is rotatably attached to the lower end of a bogie that moves on the rail, and is arranged so that its lower end slides on the upper surface of the rail. a rotating belt made of a non-magnetic material that is inserted into a gap between the magnet and the rail and rotates; It is characterized by having a dust collector with a suction port opened on the side and below the rotating belt.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. The wheels 3 of the vehicle 4 are driven to rotate and travel. A vertical shaft 10 is provided on the truck of the tow vehicle 4 in front of the tow vehicle 4 in the direction of movement, with a support frame 6 interposed therebetween. A wire brush 5 is movably attached. Further, a magnet 7 is suspended from the support frame 6 between the trolley of the tow truck 4 and the wire brush 5, that is, at the rear of the wire brush 5, and close enough to apply a magnetic force to the upper surface of the rail 2. ing.

In the gap between the rail 2 and the magnet 7, a rotating belt 8 made of a non-magnetic material with a thickness that is thin enough to pass the magnetic force is disposed, and this rotating belt 8 is attached to the support frame 6.
It is attached to a rotating shaft 9 of a motor 11 fixed to a motor 11, and is hung between rollers 16 and 17 whose both ends are supported by a pair of support frames 15.

12 is a dust collector fixed to the support frame 6,
A suction port at the tip of the suction tube 13 is opened at the side surface of the rail 2 and below the rotating belt 8.

Reference numeral 14 is a brush installed at the suction port at the tip of the suction tube 13, and the tip thereof is in contact with the lower surface of the rotating belt 8.

Now, since the wire brush 5 is attached to the shaft 10 with its center of rotation shifted from the center of the rail 2, its lower end does not contact the upper surface of the rail 2 evenly during running, so it rotates in a direction with fewer contact areas, 2. Remove iron rust or steel foreign matter adhering to the top surface of the rail 2, and remove some of it from the rail 2.
Scrape off the top. Further, fine powdered iron rust remaining on the rail 2 is completely attracted to the lower surface of the rotating belt 8 by the attraction force of the magnet 7 disposed behind it.

When this rotary belt 8 is rotated by the motor 11 while the tow wheel 4 is running, fine powdered iron rust and foreign steel particles adsorbed on the lower surface of the belt 8 rotate together with the belt 8 and move away from the rail 2 and the magnet 7. The effect of magnetic force becomes weaker. Since the suction port at the tip of the suction pipe 13 of the dust collector 12 is installed in that area, iron rust and foreign steel particles that have been magnetically attracted to the belt 8 are scraped off by the brush 14 installed in the suction port. while being automatically and continuously sucked into the dust collector 12.

The device for removing foreign matter on a rail according to the present invention is constructed and operated as described above, and has the following advantages.

1. Since the collection and removal of iron rust and steel foreign matter from the top of the rail is carried out easily and reliably, errors and fluctuations from the set speed of the towing truck are reduced, and the wheels run on steel foreign matter on the rail while running. It is said that it is possible to prevent the vibration of the towing truck that occurs due to this.

2. Even if the wire of the wire brush falls off, the magnet sweeps the wire off the rail, so the wheel 3 will not ride on it and damage the rail or wheel.

3 The speed of the bogie can be controlled with high precision,
In addition, since the vibration can be reduced, the experimental accuracy of the water tank test can be maintained at a higher level, and the accuracy of the rail can be maintained at a high level for a long period of time without requiring much effort.

4. Since the upper surface of the rail and the wheels of the tow truck are no longer scratched or unevenly worn due to steel foreign objects, the service life of the entire water tank tow truck can be significantly extended.

Although the above embodiment shows an example in which the present invention is applied to a towing truck for an aquarium, the present invention is not limited to such an embodiment, and as mentioned above, the present invention is applicable to crane hoists that are difficult to inspect on a daily basis. It is also effective when applied to rails, etc., and in short, it is effective when it is necessary to reliably collect and remove iron rust and steel foreign matter on the rails and protect and maintain the rails.
