Description

[Detailed description of the invention] The present invention relates to a work trolley equipped with a rail cleaning device, and in particular, by providing the work trolley with a rotating brush that rotates and brushes the running rail as it travels.
The present invention relates to a work trolley equipped with a rail cleaning device capable of removing foreign matter falling or adhering to the running rail while traveling.

Conventionally, in the case of work carts on which welding machines and the like used in welding lines are mounted, slag, etc. that falls or adheres to the running rails during welding can cause the running wheels to run over, abnormal wear of the rails or wheels, etc. A problem had occurred.

For this reason, the work cart required a rail sweeper for cleaning slag and the like on the traveling rails.

As a work vehicle equipped with such a rail sweeper, a work vehicle 1 as shown in FIG. 1 is conventionally known.

As shown in the figure, in this work trolley 1, a trolley 4 is placed on running rails 2 via running wheels 3, and in front of the running wheels 3 in the traveling direction of the working trolley 1 (the direction indicated by the arrow in the figure). A sweeper 5 is provided in the.

This sweeper 5 is composed of a rubber plate 6 for cleaning that slides on the surface of the running rail 2, and a support member 7 that supports this rubber plate 6 from the bottom of the trolley 4, and moves as the work trolley 1 moves. Foreign matter such as slag that has fallen onto the rail 2 is cleaned by a sweeper 5.

However, in such a sweeper 5, as described above, the rubber plate 6 and the traveling rail 2 are in sliding contact and the contact surface is always kept constant, so that the worn portion of the rubber plate 6 is fixed.

For this reason, the amount of wear on the rubber plate 6 increases, and the amount of wear on the rubber plate 6 increases.
Improper installation could lead to uneven wear.

Furthermore, as the rubber plate 6 wears out, its function as a sweeper for the running rail decreases or disappears altogether, so it is necessary to correct the mounting position of the rubber plate 6 depending on the wear status. Ta.

The present invention has been proposed to effectively solve these conventional problems.

The purpose of the present invention is to provide a rotating brush for cleaning slag, etc. on the running rail while automatically rotating as the work trolley travels, so that the contact surface or brush surface of the rotating brush, which is a sweeper, can be removed. To provide a work cart equipped with a rail cleaning device capable of always cleaning the tread surface of a traveling rail uniformly and preventing uneven wear of a rotating brush.

Another purpose of the present invention is to automatically bring the rotating brush into contact or pressure contact with the running rail surface by its own weight, so that even if the rotating brush wears out, it can function as a sweeper without having to adjust its mounting position. The purpose of the present invention is to provide a work trolley equipped with a rail cleaning device that can maintain the rails.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

In FIG. 2, reference numeral 11 is a work cart on which a welding machine, a cutting machine, etc. are mounted, and this work cart 11 has running wheels 13 on the bottom, and a running rail 1
It is movably placed on 2.

The work cart 11 has a rotating shaft 1 hanging therefrom.
A rotating brush 14 as a sweeper is provided via the brush 7 so as to be rotatable and movable up and down with its brush surface pressed against the upper surface (tread surface) of the traveling rail 12 due to its own weight.

A rotary brush 14 ('!, a brush 16 such as a nylon brush or a wire brush is planted downward at the bottom of a circular brush scrap 15, and a rotating shaft 11 is loosely inserted into the center of the brush scrap 15. A sleeve 18 is integrally provided therethrough.

The rotating brush 14 is attached to the rotating shaft 1T with the brush 16 facing downward, and is supported so as to be rotatable and movable up and down, and its own weight presses the brush surface onto the tread surface of the running rail 12.

In order to prevent the rotating brush 14 attached to the rotating shaft 17 from falling off, a stopper 19 is provided at the lower end of the rotating shaft 17 to lock the lower end of the sleeve 18.

An appropriate gap is provided between this stopper 19 and the lower end of the sleeve 18, so that when the brush 16 is worn out, the rotating brush 14 can be lowered by the gap due to its own weight. There is.

In order to rotate the rotating brush 14 with such an attachment configuration by contact friction with the running rail 12, the rotating shaft 17 is provided eccentrically from the center of the tread of the running rail 12 in the width direction.

In the illustrated example, the rotating shaft 17 is eccentrically moved toward the outside of the traveling carriage 11 (see FIG. 2), but it may be eccentrically moved toward the inner side.

Note that the corner of the tread of the traveling rail 12 is designated b, and the rotating brush 14 is
When the radius of R1 is defined as the eccentric distance from the tread center y of the R1 running rail 12 to the center 0 of the rotating shaft 17, rotational force is efficiently applied to the rotating brush 14, and the running rail 12
In order to uniformly clean the tread surface, it is preferable that the eccentric distance X is greater than or equal to the width of the tread surface, and the radius R of the rotating brush 14 is greater than or equal to the width of the tread surface.

By setting in this way, rotational moment acts on the rotating brush 14 in only one direction due to contact friction with the running rail 12, so rotational force can be efficiently applied to the rotating brush 14, and the rotational force can be efficiently applied to the rotating brush 14. brush 16
Since this covers the entire tread surface of the running rail 12, the tread surface can be uniformly cleaned.

In the illustrated example, the rotating brush 14 is disposed in front of the running wheels 13 in the traveling direction of the work cart 11 (in the direction of the arrow in FIG. 3), but as shown by the imaginary line in FIG. may be provided behind the running wheels 13a in the opposite direction.

In this case, as the work cart 11 moves backward, the traveling rail 1
You can perform the above cleaning.

Next, the operation of the present invention constructed as described above will be explained.

As shown in FIGS. 2 and 3, a work cart 11 carrying a welding machine or the like is movably placed on a traveling rail 12 such as a welding line, and the brush surface of the rotating brush 14 is When all the work carts 11 move in the direction of the arrow shown in FIGS. 3 and 4 from the state in which they are in pressure contact with the tread surface of the traveling rail 12 due to their own weight, the rotating brush 14
As the work cart 11 moves, a rotational force is applied to the brush 16 due to contact friction between the brush 16 and the running rail 12, thereby causing the rotating brush 14 to rotate in the direction of the arrow.

As a result, the rotating brush 14 brushes the tread surface of the running rail 12, so that foreign matter such as welding slag that has fallen or adhered to the surface of the running rail 12 can be removed.

In addition, foreign matter can be swept away by the centrifugal force of the rotation of the rotating brush 140, and no foreign matter will be left behind.

In this way, the traveling rail 12 on which the work cart 11 moves
Since foreign matter such as slag on the top can be cleaned, it is possible to prevent the traveling wheels 13 of the work cart 110 from riding on the foreign matter, and also prevent the traveling wheels 13 and the traveling rails 12 from being abnormally worn. .

In summary, the present invention provides the following excellent effects.

(1) The work trolley is equipped with a rotating brush that automatically rotates as it travels and cleans slag, etc. on the running rail, so the brush surface of the rotating brush is uniformly spread over the tread surface of the running rail by rotation. This makes it possible to evenly clean the tread surface and prevent uneven wear of the rotating brush.

(2) Furthermore, since the rotating brush is driven to rotate by utilizing the contact friction between the brush surface and the running rail as the work cart travels, a motor is not required, which is economical.

(3) Since the rotating brush is automatically pressed against the running rail surface by its own weight, even if the rotating brush wears out, its function as a sweeper can be maintained for a long period of time without having to adjust its mounting position. .

(4) Furthermore, since the structure is extremely simple, it can be manufactured at low cost, has few failures, and can be widely used in this type of conveyance equipment.
