Description

[Detailed description of the invention] This invention relates to covers for skid rails and other rails for mounting and transporting metal pipes, and allows the use of any synthetic resin suitable for the cover, and facilitates attachment to the rail. This makes it possible to easily replace it when it wears out.

When transporting pipes by placing them on rails, it is already common practice to cover the rails with synthetic resin covers in order to protect the pipes being transported and to eliminate noise. It is publicly known. For example, the cover is fixed to the rail by providing a recess in a synthetic resin cover, inserting a bolt that passes through the recess into a hole in the rail, and engaging a nut. It requires a lot of effort to tighten a large number of bolts and nuts. Another problem is that it is inconvenient to replace the cover when it becomes worn. There is also a product disclosed in Japanese Utility Model Publication No. 55-24006, in which a band-shaped synthetic resin is fixed to one side of a bendable metal plate by casting, and it is fixed to the metal by casting. It is impossible to select a synthetic resin that is suitable for the cover. Fixing to the rail is relatively easy as it is done by bending the end of the metal plate, but when the resin wears out, it is necessary to replace the entire cover along with the metal plate, which takes a lot of effort. This is both necessary and uneconomical.

This project solves the above problem, and includes a cover body made of synthetic resin that is shaped like a band plate and has grooves formed on both sides in the width direction along the entire length of the cover body. Insertion parts that can be inserted into the grooves and protrude toward each other are formed on both edges in the width direction of a band-like support part having a width that is approximately the same as the width of the support part, and the support part has: The main feature is that the cover body is made of a base made of a metal plate and provided with fastening parts projecting on both sides in the width direction, and the cover body is attached to the base by inserting the insertion part into the groove.

To explain the embodiment of the cover of the present invention in the drawings, reference numeral 1 is a cover body made of synthetic resin formed in the shape of a band plate, and grooves 2 extending in the length direction are formed on both sides of the cover in the width direction. It is formed over the entire length in the horizontal direction. As the synthetic resin forming the cover body 1, any synthetic resin suitable for a cover such as a small coefficient of friction can be used, and examples thereof include ultra-high molecular polyethylene, cast nylon, and phenolic resin. Reference numeral 3 denotes a mounting pedestal made of a metal plate, which is mounted at intervals in the length direction on both sides of the band-shaped support part 4, which has a width approximately the same as the width of the cover body 1. A fastening part 5 is provided in a protruding manner. 6 is on both ends of the support part 4 in the width direction,
The insertion portions are bent in mutual directions and have a protruding length that can be inserted into the grooves 2, 2 of the cover body 1. That is, in the examples of Figures 1 to 4,
Since the groove 2 is provided at a slight inclination in the length direction of the main body 1, the insertion part 6 is formed by bending the edge of the support part 4 with an inclination in the width direction. There is. In the examples shown in FIGS. 5 to 8, the groove 2 is made substantially perpendicular to the side surface of the main body 1 on which it is formed, so that the cross-sectional shape of the insertion portion 6 is inverted L-shape. . Then, the insertion parts 6, 6 are inserted into the grooves 2, 2, and the cover main body 1 is inserted into the pedestal 3.
It is attached to the support part 4 of. Therefore, the width of the support portion 4 is equal to the width of the insertion portions 6 formed on both ends thereof.
6 may be made to have a width that allows insertion into the grooves 2, 2, or may be made to be the same as, slightly larger or smaller than the width of the cover main body 1, etc.
7 is a rail.

Since the pedestal 3 in the example of FIGS. 1 to 4 is integrally formed from a single metal plate, the insertion portion 6
are formed on both side edges of the support part 4 only in the part between the fastening parts 5 and 5, but the pedestal 3 in the example of FIGS.
Since the support part 4 and the fastening part 5 are formed separately, and the fastening parts 5 are fixed to both side edges of the support part 4 by welding or the like, the insertion part 6 extends over the entire length of the support part 4. It is formed as follows. However, in the examples shown in FIGS. 5 to 8, it is also possible to make the insertion portion 6 intermittent,
In this example, the fastening parts 5 are fixed to both side surfaces of the support part 4, but they can also be fixed to the bottom wall of the support part 4 in an overlapping manner as shown in FIG. It is also possible to provide the fastening part 5 continuously over almost the entire length of the support part 4, as shown in FIG.

To fasten this cover to the rail, place the base 3 on the rail 7 side, stack it on the rail 7, bend the fastening part 5 toward the rail, and fasten it to the rail 7, as shown in FIG. Furthermore, the cover body 1 is fixed onto the rail 7 by fixing the fastening portion 5 to the rail by welding or the like. Fixation to rail 7 is as follows:
It is optional to leave the main body 1 attached to the pedestal 3, or to first fix only the pedestal 3 to the rail 7 and then attach the cover main body 1 thereto.

As mentioned above, the cover of the present case consists of the cover body 1
However, by inserting the insertion portions 6, 6 of the pedestal 3 from the ends into the grooves 2, 2 formed on both sides in the width direction over the entire length of the pedestal 3, the pedestal 3 can be removed.
Since the cover body 1 is attached to the pedestal 3, it is easy to attach the cover body 1 to the pedestal 3, and the work can be carried out efficiently. In addition, since the cover body 1 can be formed by selecting any synthetic resin suitable for its intended use, it is possible to smoothly convey objects, and it is easy to extend the service life of the cover body 1. It is.

Since the base 3 is fixed to the rail 7 by bending the fastening portion 5 toward the rail 7 as described above, the cover can be easily fixed to the rail 7. Moreover, the pedestal 3 is fixed to the rail 7 when it is separated from the cover body 1.
Alternatively, since it can be carried out in any state with the cover main body 1 attached, it can be appropriately selected depending on the conditions of execution, etc., and this can contribute to facilitating the attachment work. If the fastening parts 5 are formed intermittently in the length direction of the support part 4 as shown in FIGS. 2 and 6, the fastening parts 5 can be bent more easily and the cover can be attached to the rail 7 easily. The work can be made easier and it is also suitable for attachment to curved portions of the rail 7.

The cover body 1 and the base 3 can be separated from each other by pulling one of them in the length direction. Therefore, when the cover main body 1 becomes worn due to transporting a pipe or the like, it is pulled in its length direction and separated from the pedestal 3, and a new cover main body 1 is attached to the pedestal 3 that is already fixed to the rail 7. Since the rail body 1 can be attached easily and there is no need to replace the existing pedestal 3, the rail body 1 can be replaced easily, efficiently, and economically.

As in the example shown in FIGS. 2 and 3, the fastening part 5 is
On the other hand, if they are formed intermittently in the length direction, the pedestal 3 can be easily bent in the thickness direction of its support part 4, and the cover body 1 can be bent in the thickness direction. Therefore, even if the rail 7 is curved in the vertical direction, it is easy to attach it along the curve.
