Abstract

The invention belongs to a measuring tool, in particular to a multifunctional lift inspection ruler which is used for lift acceptance, installation, regular inspection and repair and maintenance. The inspection ruler comprises a main ruler and an auxiliary ruler, wherein the main ruler is in a J-shaped structure; the auxiliary ruler is in a T-shaped structure and installed on the main ruler and can longitudinally slide along a ruler bar of the main ruler to enable the ruler body of the auxiliary ruler and the ruler body of the main ruler to be abutted with each other; a digital display grating ruler is installed on a ruler bar of the auxiliary ruler; and a gauge stand at the end part of the ruler body of the auxiliary ruler and a gauge needle at the end part of the ruler body of the main ruler form a depth gauge. The invention has the advantages of reasonable design and artful concept, has multiple measurement functions and is a special tool during lift safety detection. The ruler can complete detection on various data during lift safety detection. The unique structure design can ensure that lift detection personnel are not limited by lift structure space during detection, saves the time and the labour, improves the work efficiency and reduces the labour intensity of working personnel.
