Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a protective device for tubular bodies such as steel pipes.

[Prior art]

Conventionally, methods for protecting the surface, threaded parts, etc. of steel tubular bodies such as seamless pipes include attaching steel sockets, semi-cylindrical spacers made of synthetic resin, etc. Methods such as wrapping the body are being implemented.

[Problem that the invention attempts to solve]

However, in such a protection method, a steel socket not only increases production cost but also has a large weight, while a semi-cylindrical spacer needs to be attached to the lower and upper halves of the tubular body, respectively. In addition, in the case of a string-like body, the work of winding it around a tubular body is troublesome, and the disposal of cutting waste after use is troublesome, among other problems.

[Means for solving problems]

Therefore, in order to solve the above-mentioned problem, in this invention, a round bar-shaped body made of flexible synthetic resin is formed into a spiral shape with a predetermined diameter, and the surface of this round bar-shaped body is formed in an embossed shape to provide protection. By adopting the tool, manufacturing costs including material costs can be reduced, and handling operations can be made easier.

[Effect]

Since the tubular body protector according to this invention uses flexible synthetic resin as the material, manufacturing costs can be reduced, and it can be attached to and removed from the tubular body by simply increasing the diameter of the helical shape with your fingers. This can be done easily, and since the surface is embossed, it will not shift after installation.

〔Example〕

Next, preferred embodiments of the tubular body protector according to the present invention will be described in detail below with reference to the accompanying drawings.

1 and 2, a tubular body protector 10 according to the present invention is constructed by forming a flexible rod-shaped body 12 made of synthetic resin into a spiral shape having a predetermined diameter. ing. In this case, the flexible rod-shaped body 12 is made by mixing and melting synthetic resin materials having different melting temperatures, such as a cross-linked product of polyethylene and polyethylene, and then melting this melted mixture under predetermined temperature and pressure conditions. It is preferable to form the flexible rod-shaped body 12 from a synthetic resin having a circular cross section with an embossment 14 formed on its surface by extrusion molding. It is preferable to adopt a method in which a rod-shaped body having a surface is wound around a wrapped body having a predetermined diameter, cooled, and then cut into a desired number of turns.

When using the tubular body protector according to the present invention constructed as described above, the diameter of the protector 10 is increased by twisting both ends 12a and 12b of the rod-like body 12 in opposite directions using fingers or the like. In this state, it is attached to a predetermined location on the tubular body A (see Fig. 3).
Further, a large number of tubular bodies to which protective equipment 10 is attached in this manner can be easily transported by using these protective equipment as spacers as they are and appropriately binding them with string members 16, etc., as shown in FIG. can.

In addition, when removing the protector 10 attached to the tubular body A, it is sufficient to appropriately pull out the protector 10 while increasing its diameter by the same operation as when attaching the protector 10.

[Effect of idea]

As mentioned above, the tubular body protector according to the present invention has an extremely simple structure, so it can not only significantly reduce manufacturing costs, but also facilitates handling operations because it can be attached and detached using its flexibility. . In addition, since the surface of the protective gear is embossed, there is no risk of it slipping off after being worn, so it not only protects the designated areas, but also can be used as a cushioning material or spacer, which prevents noise generation. It has various advantages such as the ability to simplify packaging operations, and its practical effects are extremely large.

Although the preferred embodiment of the tubular body protector according to the present invention has been described above, the present invention is not limited to this embodiment. Of course, various modifications can be made without departing from the spirit of the present invention, such as adjusting the diameter or the number of spiral turns.
