Description

  The present invention relates to a substrate adjustment tool for removing rust and coating film on the surface of a long metal body such as a steel pipe or a conduit, or for grinding the surface.

  Steel pipes, which are structural elements of steel towers, and electric pipes for the purpose of protecting electric wires, are generally coated with anticorrosive coatings that prevent the occurrence of rust, etc. Therefore, it was necessary to perform a regular repainting work.

  In this repainting work, as a pretreatment, it is essential to prepare a base material that cleanly removes the old paint film adhering to steel pipes and conduits. It is common to work with tools.

  However, in the conventional substrate adjusting tool such as the disk sander described above, the polishing surface of the polishing body is configured to be a flat surface, so that the outer peripheral surface is curved like a cylindrical long body such as a steel pipe or a conduit. In this case, since the contact is not a surface contact but a line contact, the polishing area when the polishing body is brought into contact is very narrow and the working efficiency is poor.

  In addition, when a plurality of long bodies are arranged side by side in a narrow place like a bridge conduit, the arrangement interval between the long bodies is narrow. An electric substrate adjusting tool such as a disk sander cannot be disposed in the gap between the scales, and therefore, an efficient substrate adjusting operation using an electric substrate adjusting tool such as a disk sander cannot be performed. An operator manually adjusts the base material, and such a manual operation is very troublesome because it requires enormous labor and cost, and the burden on the operator is large.

  The present invention solves such problems of the substrate adjustment work, can perform the substrate adjustment operation of a long body extremely efficiently, and is arranged in a narrow space at a narrow interval in parallel. It is an object of the present invention to provide a substrate adjustment tool that can easily perform substrate adjustment work even with a long body such as a conduit or steel pipe.

  The gist of the present invention will be described with reference to the accompanying drawings.

  Since the present invention is configured as described above, the contact area between the polishing body and the elongated body is widened, and the polishing area is widened, so that the working efficiency is dramatically improved as compared with the conventional case.

  That is, the conventional substrate adjusting tool such as a disk sander grinds the outer peripheral surface of a cylindrical long body such as a steel pipe or a conduit tube with a line, not a surface, so that the polishing area is very narrow. Although the working efficiency was extremely poor, the present invention fits a long body, specifically, abutting and fitting so as to surround the outer peripheral surface of the long body. It becomes a very large polishing area, and the substrate adjustment work can be performed efficiently.

  Moreover, even for long bodies such as electric pipes and steel pipes that are arranged side by side in a narrow space in a narrow space, conventional power tools such as disc sanders (base adjustment tools) can be used for base adjustment work. Parts that have been manually adjusted and cannot be adjusted manually can be adjusted very easily using the substrate adjustment tool of the present invention. It will be a revolutionary substrate adjustment tool with extremely high practicality, such as shortening and construction cost reduction.

  Further, in the present invention, since the polishing is reliably performed in a state where the polishing body is in good pressure contact with the outer peripheral surface of the long body, the substrate adjustment of the outer peripheral surface of the long body can be performed extremely effectively, In addition, since this pressure contact is made by the elasticity of the polishing body itself, it is not necessary to provide pressing means for pressing the polishing body against the long body, and the fitted body has a simple and slim structure. Therefore, even if the gap between the elongated bodies is narrow, the fitted body can be fitted into the elongated body through the fitted half through the narrow gap. Even if the adjustment tool cannot perform the substrate adjustment work and the operator manually adjusts the substrate, the substrate adjustment operation can be performed very easily.

  Further, in the present invention, since the fitted body is fitted so as to surround the entire outer peripheral surface of the long body, it is efficiently and evenly distributed without moving the fitted body in the circumferential direction of the long body one by one. It becomes a substrate adjustment tool that is more practical and capable of performing substrate adjustment.

  Further, in the invention described in claim 4, the operability is further improved, and the substrate adjustment tool having excellent practicality capable of performing the substrate adjustment work efficiently can be obtained.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  In the present invention, since the sheet-like polishing body 5 surrounding and contacting the outer peripheral surface of the long body 1 is provided on the inside of the fitting body 3 to be fitted to the long body 1, the sheet-like polishing body 5 is provided. The provided body 3 is fitted on the long body 1, and the driving body 4 is driven to reciprocate and move the fitted body 3 so that the fitted body 3 of the long body 1 is fitted. Since the outer peripheral surface of the portion can be evenly polished without moving the fitted body 3 in the circumferential direction, the length of the long body 1 can be extremely efficiently compared to a base material adjusting tool such as a conventional disk sander. The substrate adjustment work can be performed.

  In addition, in the case where a plurality of long bodies 1 are arranged side by side in a narrow space, the arrangement interval between the long bodies 1 is narrowed. An electric base material adjusting tool such as a disk sander cannot be disposed in the gap 9 between them. Therefore, the operator manually adjusts the base material. The base material to be adjusted is obtained by separating the mating body 3 made of 3b from the other half half 3b with respect to one mating half 3a or turning in the opening direction into a half-cracked state. Even if the gap 9 between the long bodies 1 is narrow, the fitted body 3 can be easily fitted to the long body 1.

  That is, according to the present invention, the other half half 3b is provided so that it can be freely opened and closed with respect to the half half 3a, and the half half 3b is pivoted in the opening direction. Since the other half 3a is in a half-cracked state with respect to the half 3a, the half-cracked half-cracked half-body 3a, 3b can be obtained by making the half-cracked half-cracked. On the other hand, specifically, the side that is not on the moving base 2 side has a slim shape that can pass through the narrow gap 9 between the long bodies 1 and can easily pass through the gap 9 between the long bodies 1. The to-be-fitted body 3 can be fitted to the scale body 1.

  In addition, the sheet-like polishing body 5 that surrounds and contacts the outer peripheral surface of the long body 1 provided inside the fitting body 3 by being fitted to the long body 1 in this way is the long body 1. When the driving device 4 is driven, the fitted body 3 reciprocates along the long body 1 with respect to the moving base 2, and the fitted body 3 reciprocates. By sliding, the sheet-like polishing body 5 pressed and adhered to the outer peripheral surface of the long body 1 reciprocates the outer peripheral surface of the long body 1. 1 basis adjustment will be made.

  Therefore, by moving the moving base 2 little by little along the long body 1 while the driving device 4 is driven, the base of the long body 1 is continuously adjusted in the length direction.

  Therefore, if the substrate adjustment tool of the present invention is used for the substrate adjustment work of the long body 1 such as a wire pipe or a steel pipe arranged in a narrow space in a narrow space, the operator can manually perform the substrate. It is possible to avoid the adjustment work, and therefore, the work efficiency is remarkably improved, and the groundwork adjustment tool is extremely excellent in practicality. For example, the work period can be greatly shortened and the construction cost can be reduced.
