Description
Technical field
The utility model relates to elevator detection fields, and in particular to a kind of elevator door deflection detector.
Background technique
Along with the great-leap-forward development of Urbanization in China, the living standard of the people is continuously improved, elevator conduct
A kind of convenience means of transport is widely used in a variety of applications, and has become the necessity in people's life, and elevator is related to as one kind
And the high tool of frequency of use of passenger's personal safety, safety just seem increasingly important, the stability of operation conditions with
Safety is increasingly paid close attention to by people, and about the report of elevator safety accident, the moment reminds special inspection personnel lift peace
Full inspection surveys the importance of work, and the data from State General Administration for Quality Supervision show that common elevator accident is mainly rushed to summit in life
Accident, crouching bottom accident, door system accident and totally 4 kinds of other accidents, wherein door system accident proportion is maximum (accounting for about 80%),
It followed by rushes to summit or crouching bottom accident (accounting for about 15%), other accidents 5%, and the main reason for door system accident is then passenger's shock layer
Door causes layer door to damage, therefore the inspection of door system intensity is particularly important.
In elevator safety standard GB/T 7588-2003 7.2.3.1 section, it is desirable that elevator door mechanical strength need to expire
Sufficient the following conditions: with being evenly distributed on 5cm2Round or rectangular area on 300N power, act perpendicularly to be detected elevator
Any position on any one face of layer door, elevator door should be able to meet without permanent deformation, elastic deformation no more than 15mm, and
And it is unaffected with the security function of elevator door after test during testing.
However, the power of the 300N required in elevator safety national standard, is only merely an average adult in positive reason
The average thrust that can apply under condition, but often hit generated impact force by personnel and can achieve 1000N, for this purpose, European Union
In the elevator manufacture and installation safety standard prEN81-20:2014 of newest revision, the electricity for personnel's impact force is increased
Terraced layer door mechanical strength new demand standard, 2014, China also increased original elevator safety standard GB/T 7588-2003
Add No. 1 modification single, modified and provide to point out in list, waits stop direction to act perpendicularly to electricity from elevator with the static(al) of 1000N
Any position on terraced door leaf or doorframe, applied force are evenly distributed in 100cm2Round or rectangular area on when, elevator layer
Door would not influence the obvious permanent deformation of operation function and safety, the formulation of new standard, it is contemplated that due to personnel's impulsive contact force
It may be influenced caused by elevator door, greatly improve elevator safety standard, although new elevator door safety standard
The generation that personnel fall casualty accident will be efficiently reduced, but also to the method for staff's on-site test layer door mechanical strength
More stringent requirements are proposed with equipment.
The mechanical strength of elevator door is usually to be determined by the result of pendulum impact test at present.The dress of Charpy impact test
The pendulum for setting the shot built in pendulum bracket and moccasin with certain altitude forms, pendulum to the impact force of elevator door by
The gravitional force of pendulum converts during the pendulum bottom, wants to make the impact force of pendulum reach national safety standard
It asks, pendulum needs to be pulled to corresponding height, therefore the general volume of pendulum bracket is larger, in order to guarantee that pendulum fills in impact process
The stability set, pendulum bracket are generally also heavier.Have the characteristics that volume is big and quality weight according to pendulum test device, it is portable
Property it is bad, on-site test suffers from the limitation of room and time factor, and Installation And Test has inconvenience, therefore, elevator door machine
Tool intensity still lacks efficient in-situ check and test method.
