Multifunctional lift inspection ruler

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.

Description

1. Technical field [0001] The invention belongs to measuring tools, in particular to a detection ruler used for elevator inspection, installation, regular inspection and maintenance. 2. Background technology [0002] At present, the country has strict inspection standards for the safe operation of elevators. The current inspection content and requirements of the "Elevator Supervision and Inspection Regulations" issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China stipulate that the safety inspection of elevators should ensure that such things as: door lock hook, lock arm and moving parts The contact action is flexible, and the minimum engaging length of the locking element before the electrical safety device acts is 7mm; in normal operation and the car does not stop in the unlocking area, the landing door cannot be opened, if a landing door or car door (or multiple landing doors Any one of the doors) is open...

AI Technical Summary

Problems solved by technology

Due to the tight and complex internal structure of the elevator, the existing measurement tools are difficult to use due to the limited position and space of the measured object, and the sight of the inspectors is limited so that accurate readings cannot be made, which makes the measurement extremely difficult, not only time-consuming and laborious, but also difficult to guarantee the measurement data. the accuracy of
