Jig apparatus for straight degree survey and straight degree survey method using the same {Jig apparatus for straight degree survey and straight degree survey method using the same}

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. More specifically, the present invention relates to a straightness measurement method of various rails, such as the rail of an overhead crane, to a moving object installed on the rail. It relates to a jig device for straightness measurement that allows accurate measurement without separating the moving object and to a straightness measurement method using the same.

In general, factories handling large, heavy goods have overhead cranes installed inside the factory building to facilitate the movement of goods.

A common type of overhead crane is to install a traveling rail on a structure such as a factory building, then place the crane body on it and run it along the rail to perform hoisting work.

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

Therefore, regular inspection of the straightness of the rails of the overhead crane is necessary, but there are always difficulties in the work due to the fact that the crane body of the overhead crane is always installed on the rail, covering some sections of the rail. In other words, due to the crane body that is always installed on the rail while covering some sections of the rail, one end of the rail in the longitudinal direction (hereinafter referred to as the “start point”) can be seen from the other end in the longitudinal direction (hereinafter referred to as the “end point”). As a result, the straightness of the rails of the overhead crane could not be confirmed.

Accordingly, the present applicant proposed the present invention as a technology that can accurately measure the straightness of the rail even when the crane body of the overhead crane is located on the rail while covering some sections of the rail.
