Multifunctional elevator inspection ruler

Abstract

The invention relates to a multifunctional elevator inspection ruler, including a door lock engagement depth inspection ruler and inspection rulers for other items of an elevator which is hinged or detachably connected to one end of the door lock engagement depth inspection ruler; and the inspection rulers for other items of an elevator include an extension scale, a filler gauge and / or a comb plate engagement depth inspection ruler, where one ends of the door lock engagement depth inspection ruler is hinged or detachably connected to one end of the extension scale, filler gauge and / or comb plate engagement depth inspection ruler. According to the multifunctional elevator inspection ruler provided by the invention, the door lock engagement depth inspection ruler is hinged or detachably connected to one end of the extension scale, the filler gauge and the comb plate engagement depth inspection ruler through a locknut A, the multifunctional elevator inspection ruler can be carried conveniently, and one of rulers can also be dismounted to be used alone, any two or more of the door lock engagement depth inspection ruler and the extension scale, the filler gauge and the comb plate engagement depth inspection ruler can be separately hinged or detachably connected, and can be matched and mounted by a user himself according to work requirements, and both time and labor are saved during work.

Description

technical field [0001] The invention relates to an elevator multifunctional inspection ruler. Background technique [0002] In modern high-rise buildings, elevators are infrastructure closely related to people's lives. The safety of elevator operation is related to the safety of people's lives and property. The state attaches great importance to elevator safety, implements mandatory management, and continues to explore, gradually forming an effective safety supervision system to ensure normal production and living order. However, the elevator accident rate in my country is still relatively high at present, and the momentum of general safety accidents has not been fundamentally reversed. Major accidents occur from time to time, and the safety situation is still severe. [0003] With the rapid growth of the number of elevators, elevator accidents such as falling, shearing, extrusion, impact, electric shock and burns have increased in recent years. [0004] For the locking o...

Problems solved by technology

The meshing depth of the comb teeth of the comb plate and the tooth groove of the pedal surface should be at least 4mm, and the clearance between the comb teeth of the comb tooth plate and the tooth groove of the pedal surface should be within 4mm. There is no special measuring tool for on-site measurement of this data. Combining measurement with a steel ruler is time-consuming and labor-intensive

[0012] In order to ensure the safe operation of the elevator, accurate, convenient and efficient inspection instruments are required. However, there are many types of inspection instruments currently used, and they are inconvenient to carry. Uncertainty, and the measurement is time-consuming and laborious, and the repetition is cumbersome
