The present invention relates to a jig device for straightness measurement in the field of geodetic surveying technology and a straightness measurement method using the same, and more particularly, to a movable body installed on the rail for measuring the straightness of various rails such as a rail of an overhead crane It relates to a jig device for straightness measurement and a straightness measurement method using the same, which can be accurately performed in a state in which the interference of the moving body is excluded without separating the jig device.

In general, in a factory handling large and heavy items, an overhead crane is installed inside the factory building for easy movement of the items.

It is common for such an overhead crane to perform hoisting work while driving along the rail by installing a driving rail on a structure such as a factory building and then placing a crane body thereon.

In addition, in order for the crane body of the overhead crane to run stably and smoothly along the rail, the straight state of the rail (hereinafter referred to as “straightness”) must be well maintained. In other words, if the straightness of the rail is not well maintained, the risk of the crane body derailing from the rail increases, and the derailment of the crane body may lead to a serious accident.

Therefore, it is necessary to check the rail straightness of the overhead crane regularly, but there are always difficulties in operation due to the crane body of the overhead crane being always installed on the rail while covering some sections of the rail. In other words, you can see from one end of the length of the rail (hereinafter referred to as “start point”) to the other end of the length direction (hereinafter referred to as “end point”) due to the crane body always installed on the rail while covering some sections of the rail. Therefore, it was not possible to check the straightness of the rail of the overhead crane.

Accordingly, the present applicant has proposed the present invention as a technology capable of accurately measuring the straightness of a corresponding rail even when the crane body of the overhead crane is positioned on the corresponding rail while covering a portion of the rail.
