Description

[Detailed Description of the Invention] The present invention relates to the structure of a guide rail that guides the running of a bogie equipped with a welding torch or fusing torch nozzle, and in particular, the rail is provided with a rack that engages with the pinion of the bogie to run. The rail is constructed so that bending along the travel curve can be easily performed.

As the automation and efficiency of welding and fusing are progressing, these torch support carts are being moved along welding lines and fusing lines.

Further, in welding, vertical and inclined welding are also increasingly automated, and guide rails are used to ensure the carriage moves in each of these positions.

These guide rails include those that only guide the trolley and have other traction chains or wires run on them, or
There are some models in which the drive wheel installed on the trolley contacts the surface of the guide rail and causes the trolley to run by friction, but these are only used in special cases, and most have long racks on the guide rail side. A device is used in which a pinion is fixedly installed and engages with a pinion formed on the truck to move the truck.

Further, these racks are provided on the top side of the guide rail, and are arranged approximately in the center thereof so as to engage with the pinion on the truck side.

On the other hand, guide rails are designed to facilitate handling.
It is made of a light metal material such as aluminum, and has a complicated cross-sectional shape in order to maintain strength to support the bogie and guide wire.

FIG. 1 is a sectional view showing a typical example of such a conventional guide rail, in which a guide rail 1 has guide grooves 2, 2 formed on both sides thereof to engage guide wheels (not shown) of a bogie, A rack mounting portion 3 is formed on the top surface (the top surface in the figure, but may also be the side surface during installation), and the rack 4 is fixedly installed.

The rack 4 is detachably provided on the mounting portion 3 and is fixed with a set screw 4' (FIG. 2).

By the way, such a guide rail needs to be formed along the welding or fusing line, and there is no problem when these running lines are straight, but when the running line is curved, the guide rail 1 must be formed. It is necessary to bend it to follow these travel curves.

These bending processes are performed manually using tools or mechanically using bending rolls, but the rack 4 fixed to the rail is often made of a metal material different from the rail material. Since it is provided at the center of the width and on the upper side, it is away from the bending center line in plan view, and the amount of strain caused by bending is large, causing the rack 4 to be stretched or tightened.

As a result, the rack 4 may be damaged or the running may be hindered, so when bending the rail, do not
The rack 4 is then bent in a separate process to inspect the pitch and correct any irregularities.

Therefore, bending the guide rail required a long time and labor, and could not be easily carried out.

That is, as shown in the sectional view of FIG. 8, the rack 4 is removed from the guide rail 1, and the rack 4 is bent using a press or a bending roll or the like, and the rack 5 is bent along the guide rail 1.

In addition, the rack 4 is bent in a separate process using similar equipment and tools, and in some cases, the bending process is performed while being heat-treated, which is time-consuming.

The present invention has been made with attention to these points, and aims to provide a guide rail that can be bent with the rack attached when bending the guide rail, and that does not disturb the pitch of the rack.

However, in this invention, the rack is provided on a guide rail having a horizontally elongated cross section and is arranged on the side surface of the guide rail, and is located approximately in the center of the rail in the thickness direction. It is structured like this.

The present invention will be described below based on the drawings, but the drawings show one example of specific implementation, and the present invention is not limited to these illustrated examples, but can be applied to guide rails with other configurations in accordance with the spirit of the descriptions described above and later. can be similarly applied.

Furthermore, the embodiments described in the claims for utility model registration are not limited to the present invention.

FIG. 4 is a cross-sectional view of the present invention applied to a solid thick-walled rail body 6, and FIG. forming the teeth 9'.

The toothed portion 9 is formed approximately in the center of the rail body in the thickness direction, and forms rack teeth 9' having an appropriate tooth width and pitch.

And on both sides of the rail body 6, there are sliding surfaces 7 on the top and bottom respectively.
is formed and serves as a guide surface for a guide roller 8 which is freely supported on a cart (not shown).

Reference numeral 10 denotes a leg, and the rail main body 6 is fixed to the top of the leg with a bolt 10', and a permanent magnetic force 11 for attraction is attached to each end of the leg 10 with a mounting screw 11.

The main part of the present invention lies in the configuration of the guide rail, and the shape of the legs 10, the means for attaching them, and the permanent magnets are as follows:
Other configurations and other means may be used.

FIG. 6 is a sectional view in which the present invention is applied to a medium-thin rail 16 in which the central portion of the rail width is formed with a thin wall, and the thick wall portions 17 on both sides.
．． 17 are each formed with a sliding surface 7, and rack teeth 18 are provided on one side of the thick walled portion.

When attaching the rack teeth 18, a fitting groove is formed in the center of the thick wall portion 17 in the thickness direction, and the rack teeth 18 are fitted into the groove to penetrate through the thick wall portion (1) 7. Constructed to be detachable using fixing screws, etc.

If necessary, as shown in the example in Fig. 4, the rack tooth 1
It is also possible to form the eight parts integrally and then carve the teeth.

In addition, in such a rail, the rack teeth 18 can be placed on either the left or right side by changing the mounting surface of the legs 10, but if necessary, rack teeth can be provided on both sides (see Fig. 7). ).

The guide rail of the present invention, in which rack teeth are formed on the side surface of the guide rail and at the center in the thickness direction of the rail, has a stress line surface that attempts to bend the rail body and a stress line surface that attempts to bend the rack. In almost the same way, the rack does not undergo any expansion or contraction that would cause it to curve up or down with respect to the bending plane, and since the difference between these is small, the rail can be bent while the rack teeth are formed or attached.

In addition, since it can be bent at the center of the rack tooth width, there is almost no expansion or contraction, and the cart can be moved smoothly as it is.

Furthermore, since the rack teeth are thinner than the rail body, there is less pitch difference (inclination) in the tooth width direction, allowing the pinion to rotate and move smoothly even with a small bending radius. Can be done.

In addition, in these examples, the tooth width direction of the rack teeth attached to or carved on the rail was along the thickness direction of the rail, but the rack tooth width direction was set along the width direction of the rail. Even if it is formed, it can be implemented in the same way.

FIG. 8 shows this applied to the rail main body 6 shown in the preceding FIG. 4, and FIG. 9 shows a part of its right side.

That is, the teeth 20 formed on the rack toothed portion 9 are directed upward (
(in the figure).

The textbook 20 is formed by a suitable method such as forging, and the pinion is engaged as shown at 19.

Further, the same operation can be carried out even if the textbook 20 is formed facing downward.

Even with this configuration, the rack is located at the center in the thickness direction of the rail body and is disposed on the side, so that it can be bent along with the rail body without disturbing the pitch of the rack, as described above. Can be processed.

As described above, according to the present invention, the rail can be bent with the rack attached, making the bending work extremely easy and can be done in a short time without the need for special tools.
