| 简介 |
The present invention relates to a guide device for cutting a cast iron pipe, which is provided : to prevent a generation of a flaw due to a water leak because of a poor cutting such as sliding a cutting surface or forming a stepped pulley or a curvature in the cutting surface etc. when a worker cuts a cast iron pipe manually by using a hand grinder; to use the guide device conveniently in a work field since a worker carries and moves the guide device conveniently; to perform easily that an unskilled worker cuts the cast iron pipe at a right angle; and to shorten a working time and to minimize a risk on a task because a post-process is not necessary. The guide apparatus of the present invention comprises : a first and a second guide main body, where a guide member having a cylindrical guide surface which is perpendicular to a length direction is equipped in both ends, and which is formed to surround an outer circumference of a cast-iron pipe; a hinge member for connecting one end of the first and the second guide main body to be able to be rotated mutually; a combining apparatus for combining and separating the other end of the first and the second guide main body; and a fixating member for fixating a second guide main body to the cast-iron pipe by being screw-combined with the second guide main body. Multiple guide members are divided and formed, and fixated to be able to be attached and detached by each fixing screws, and a rectangular abrasion-confirming groove is formed. |
